SANtricity ES Concepts for Version 10.77
These topics provide the conceptual framework necessary to understand the features and functions of the
SANtricity ES Storage Manager for Version 10.77.
SANtricity_10.77 February 2011
LSI Corporation

Storing Your Data
The topics in this section describe the basic storage concepts, methods for managing storage arrays,
including data-protection strategies, and multi-path failover drivers.
For additional information and detailed procedures for the options described in this section, refer to the online
help topics for your version of the storage management software.
Storage Arrays
A storage array has redundant components, including drives, controllers, power supplies, and fans. These
redundant components keep the storage array operational if a single component fails.
The storage array configuration provides a secure and robust system with which to store large amounts
of data and allows for a variety of backup and retrieval scenarios. Administrators can set up the storage
management software to maintain a specific level of security and configuration on the storage area network,
such that the network requires little human interaction to perform its daily functions.
Storage Area Networks
A storage area network (SAN) transfers data between computers and storage systems. A SAN is comprised
of many hardware components. Each hardware component might have a device manager or third-party
management software.
A SAN includes one or more storage arrays that are managed by one or more servers or hosts running the
SANtricity ES Storage Manager.
NOTE The SANtricity ES Storage Manager software is also referred to as the storage management
software.
You can use the storage management software to add, monitor, manage, and remove the storage arrays on
your SAN.
Within the storage management software, you can configure the data to be stored in a particular configuration
over a series of physical storage components and logical (virtual) storage components.
The I/O data and management instructions are sent from a host to the controllers in the storage array. When
the I/O data reaches the controllers, they are distributed across a series of drives, which are mounted in trays.
The SAN can also include storage management stations, which also run the storage management software.
A storage management station manages the storage arrays but does not send I/O data to them. Although
physical storage array configurations vary, all SANs work using these basic principles.
Management Methods
Depending on your system configuration, you can use an out-of-band management method, an in-band
management method, or both to manage a storage array controller from a storage management station or
host.
IMPORTANT A maximum of eight storage management stations can concurrently monitor an out-of-
band managed storage array. This limit does not apply to systems that manage the storage array through the
in-band management method.
SANtricity_10.77 February 2011
LSI Corporation
- 34 -
Out-of-Band Management
You can use the out-of-band management method to manage a storage array directly over the network
through an Ethernet connection, from a storage management station to the ethernet port on the controllers.
This management method lets you manage all of the functions in the storage array.
IMPORTANT Storage management stations require Transmission Control Protocol/Internet Protocol
(TCP/IP) to support the out-of-band management of storage arrays.
In-Band Management
You can use the in-band management method to manage a storage array in which the controllers are
managed through an I/O connection from a storage management station to a host that is running host-agent
software. The I/O connection can be Serial Attached SCSI (SAS), Fibre Channel (FC), or internet SCSI
(iSCSI). The host-agent software receives communication from the storage management client software
and passes it to the storage array controllers along an I/O connection. The controllers also use the I/O
connections to send event information back to the storage management station through the host.
When you add storage arrays by using this management method, you must specify only the host name or IP
address of the host. After you add the specific host name or IP address, the host-agent software automatically
detects any storage arrays that are connected to that host.
NOTE Systems running desktop (non-server) Windows operating systems and desktop Linux operating
systems can be used only as storage management stations. You cannot use systems running desktop
operating systems to perform I/O to the storage array and to run the host-agent software.
RAID Levels and Data Redundancy
RAID is an acronym for Redundant Array of Independent Disks. The storage solution stores the same data or
information about the data (parity) in different places on multiple hard drives. Data can be written in parallel to
multiple drives, which can improve performance. If a drive fails, the redundant data or parity data is used to
regenerate the data on the replacement drive.
RAID relies on a series of configurations, called levels, to determine how user data and redundancy data are
written to and retrieved from the drives. Each level provides different performance features and protection
features. The storage management software offers six formal RAID level configurations: RAID Level 0, RAID
Level 1, RAID Level 3, RAID Level 5, RAID Level 6, and RAID Level 10.
RAID Level 1, RAID Level 3, RAID Level 5, RAID Level 6, and RAID Level 10 write redundancy data to the
drive media for fault tolerance. The redundancy data might be a copy of the data or parity data. Parity data
is derived through a logical operation on the data, and is used for reconstruction of lost data. The parity data
might exist on only one drive, or the parity data might be distributed among all of the drives in a volume group.
The controller logically groups a set of drives together to create a volume group. Each volume group can
contain one or more volumes. You can configure only one RAID level across each volume group. Each
volume group stores its own redundancy data. The capacity of the volume group is the aggregate capacity of
the member drives, minus the capacity that is reserved for redundancy data. The amount of capacity needed
for redundancy data depends on the RAID level used.

Dynamic RAID-Level Migration
Dynamic RAID-Level Migration (DRM) is a modification operation that lets you change the RAID level on
a selected volume group without impacting the I/O. You can continue to access data on volume groups,
volumes, and drives during the migration process.
The volume group must contain sufficient free space and the required number of drives, or the DRM request
is rejected. You cannot cancel the DRM operation after the process begins.
NOTE If RAID Level 6 is a premium feature on your storage array, you must enable RAID Level 6 with
a feature key file before migrating a volume group to RAID Level 6.
RAID Level Configuration Table
RAID Level Short Description Detailed Description
RAID Level 0 No protection against
loss of a drive (non-
redundant), striping
mode
A minimum of one drive is required for RAID
Level 0.
RAID Level 0 can use the maximum number
of drives in a storage array.
You can use RAID Level 0 for high-
performance needs, but it does not provide
data redundancy.
Data is striped across all of the drives in the
volume group.
Do not use this RAID level for high data-
availability needs. RAID Level 0 is better for
non-critical data.
A single drive failure in a volume group causes
all of the volumes associated with the volume
group to fail, and data loss will occur
RAID Level 1
or RAID Level
10
Striping and mirroring
mode A minimum of two drives are required for
RAID Level 1: one for the user data and one
for the mirrored data. If you select four or
more drives, RAID Level 10 is automatically
configured across the volume group: two
drives for the user data, and two drives for the
mirrored data.
RAID Level 1 and RAID Level 10 can use the
maximum number of drives in a storage array.
RAID Level 1 and RAID Level 10 typically
provide the best write performance, but not in
all cases. On a RAID Level 1 volume, data is
written to a duplicate drive. On a RAID Level
10 volume, data is striped across mirrored
pairs.
If one of the drives in a drive-pair fails, the
system can instantly switch to the other drive
without any loss of data or service.
SANtricity_10.77 February 2011
LSI Corporation
- 36 -
RAID Level Short Description Detailed Description
RAID Level 1 and RAID Level 10 use drive
mirroring to make an exact copy from one
drive to another.
A single drive failure causes associated
volumes to become degraded, but the mirror
drive allows access to the data.
Two or more drive failures in a volume group
causes the volumes associated with the
volume group to fail, and data loss will occur.
RAID Level 3 High-bandwidth mode A minimum of three drives is required for RAID
Level 3.
RAID Level 3 is limited to a maximum of 30
drives in a volume group.
RAID Level 3 stripes both user data and
redundancy data (parity) across the drives.
RAID Level 3 uses the equivalent of the
capacity of one drive (in a volume group) for
redundancy data.
RAID Level 3 is used for applications with
large data transfers, such as multimedia or
medical imaging that write and read large
sequential chunks of data.
A single drive failure in a volume group causes
the associated volumes to become degraded,
but the redundancy data allows access to the
data.
Two or more drive failures in a volume group
causes the volumes associated with the
volume group to fail, and data loss will occur.
RAID Level 5 High I/O mode A minimum of three drives is required for RAID
Level 5.
RAID Level 5 is limited to a maximum of 30
drives in a volume group.
RAID Level 5 stripes both user data and
redundancy data (parity) across the drives.
RAID Level 5 uses the equivalent of the
capacity of one drive (in a volume group) for
redundancy data.
A single drive failure in a volume group causes
associated volumes to become degraded,
but the redundancy data allows access to the
data.
SANtricity_10.77 February 2011
LSI Corporation

RAID Level Short Description Detailed Description
Two or more drive failures in a volume group
causes the volumes associated with the
volume group to fail, and data loss will occur.
RAID Level 6 High I/O mode with
simultaneous drive
failure protection
A minimum of five drives is required for RAID
Level 6.
RAID Level 6 is limited to a maximum of 30
drives in a volume group.
RAID Level 6 stripes both user data and
redundancy data (parity) across the drives.
RAID Level 6 uses the equivalent of the
capacity of two drives (in a volume group) for
redundancy data.
RAID Level 6 provides the best data
availability. RAID Level 6 protects against
the simultaneous failure of two volume group
member drives by using two independent
error-correction schemes.
Hardware Redundancy
Data-protection strategies provided by the storage array hardware include controller cache memory, hot spare
drives, background media scans, and channel protection.
Controller Cache Memory
Write caching, or caching a drive segment to a memory buffer before writing to the drive, can increase I/O
performance during data transfers.
Write-cache mirroring protects data during a controller-memory failure or a cache-memory failure. When
you enable write cache, cached data is mirrored across two redundant controllers with the same cache size.
Therefore, if one controller fails, the alternate controller can complete all outstanding write operations.
To prevent data loss or corruption, the controller periodically writes cache data to a drive (flushes the cache)
when the amount of unwritten data in the cache reaches a certain level, called a start percentage, or when
data has been in the cache for a predetermined amount of time. The controller continues to write data to
a drive until the amount of data in the cache drops to a stop percentage level. You can configure the start
percentage and the stop percentage to suit your own storage requirements. For example, you can specify
that the controller start flushing the cache when it reaches 80-percent full and stop flushing the cache when it
reaches 16-percent full.
In case of power outages, data in the controller cache memory is protected. Controller trays and controller-
drive trays contain batteries that protect the data in the cache by maintaining a level of power until the data
can be written to the drive media or a flash memory card.
If the controller supports a flash memory card, the cache data can be written to the flash memory card when a
power outage occurs. For example, the CDE2600 controller-drive tray supports a flash memory card to write
the cache data. The battery is only needed to maintain power while the data in the cache is written to the flash
memory card. The flash memory card provides nonvolatile backup of the cache data in case of long power
outages. When power is restored to the controllers, the cache data can be read from the flash memory card.
SANtricity_10.77 February 2011
LSI Corporation
- 38 -
If a power outage occurs when there is no UPS, and there is no battery or the battery is damaged, the data in
the cache that has not been written to the drive media is lost. This situation occurs even if the data is mirrored
to the cache memory of both controllers. It is, therefore, important to change the batteries in the controller tray
and the controller-drive tray at the recommended time intervals.
Tray Loss Protection
When you create a volume group using the tray loss protection feature, all of the drives in the volume group
are found in different drive trays. Tray loss protection provides more data protection if access to the tray is
lost. This feature is used by default when you choose the automatic configuration option.
Tray loss protection depends on the number of trays that are available, the value set for the Redundant
Array of Independent Disks (RAID) level, and the number of drives in the volume group. For example, tray
loss protection cannot be achieved if a RAID Level 5 volume group is comprised of eight drives, but there
are only three trays. Configuring your volume groups to have tray loss protection is recommended. If your
configuration supports the minimum number of drive trays for your RAID level, create your volume groups to
have tray loss protection.
RAID Level Criteria for Tray Loss Protection
RAID Level 0 No tray loss protection (RAID Level 0 does
not provide redundancy).
RAID Level 1 or RAID
Level 10 For RAID Level 1, the volume group must use
a minimum of two drives found in separate
trays. For RAID Level 10, the volume group
must use a minimum of four drives found in
separate trays.
RAID Level 3 The volume group must use a minimum of
three drives found in separate trays.
RAID Level 5 The volume group must use a minimum of
three drives found in separate trays.
RAID Level 6 The volume group must use a minimum of
five drives, with a maximum of two drives in
any tray.
Drawer Loss Protection
Drawer loss protection is a characteristic of a volume group, which is available only in the DE6900 drive tray.
In drive trays that contain drives in drawers, a drawer failure can lead to inaccessibility of data on the volumes
in a volume group. A drawer might fail because of a loss of power, a failure of an environmental services
monitor (ESM), or a failure of an internal component within the drawer.
The availability of drawer loss protection for a volume group is based on the location of the drives that
comprise the volume group. In the event of a single drawer failure, data on the volumes in a volume group
remains accessible if the volume group has drawer loss protection. If a drawer fails and the volume group is
drawer loss protected, the volume group changes to Degraded status, and the data remains accessible.
To achieve drawer loss protection, make sure that the drives that comprise a volume group are located in
different drawers with respect to their RAID levels as shown in this table.

RAID Level Criteria for Drawer Loss Protection
RAID Level 3 and
RAID Level 5 RAID Level 3 and RAID Level 5 require a minimum of three drives. Place
all of the drives in different drawers for a RAID Level 3 volume group and
for a RAID Level 5 volume group to achieve drawer loss protection. Drawer
loss protection cannot be achieved for RAID Level 3 and RAID Level 5 if
more than one drive is placed in the same drawer.
RAID Level 6 RAID Level 6 requires a minimum of five drives. Place all of the drives in
different drawers or place a maximum of two drives in the same drawer
and the remaining drives in different drawers to achieve drawer loss
protection for a RAID Level 6 volume group.
RAID Level 1 and
RAID Level 10 RAID Level 1 requires a minimum of two drives. Make sure that each drive
in a mirrored pair is located in a different drawer.
If you make sure that each drive in a mirrored pair is located in a different
drawer, you can have more than two drives of the volume group within the
same drawer. For example, if you create a RAID Level 1 volume group
with six drives (three mirrored pairs), you can achieve the drawer loss
protection for the volume group with only two drawers as shown in this
example:
Six-drive RAID Level 1 volume group:
Mirror pair 1 = Drive in tray 1, drawer 1, slot 1, and drive in tray 1,
drawer 2, slot 1
Mirror pair 2 = Drive in tray 1, drawer 1, slot 2, and drive in tray 1,
drawer 2, slot 2
Mirror pair 3 = Drive in tray 1, drawer 1, slot 3, and drive in tray 2,
drawer 2, slot 3
RAID Level 10 requires a minimum of four drives. Make sure that each
drive in a mirrored pair is located in a different drawer.
RAID Level 0 You cannot achieve drawer loss protection because the RAID Level 0
volume group does not have redundancy.
NOTE If you create a volume group by using the Automatic drive selection method, the storage
management software attempts to choose drives that provide drawer loss protection. If you create a volume
group by using the Manual drive selection method, you must use the criteria that are specified in the previous
table. For more information about how to create volume groups, refer to the Using the Create Volume Group
Wizard online help topic in the Array Management Window of SANtricity ES Storage Manager.
If a volume group already has a Degraded status due to a failed drive when a drawer fails, drawer loss
protection does not protect the volume group. The data on the volumes becomes inaccessible.
Hot Spare Drives
A valuable strategy to protect data is to assign available drives in the storage array as hot spare drives. A hot
spare is a drive, containing no data, that acts as a standby in the storage array in case a drive fails in a RAID
Level 1, RAID Level 3, RAID Level 5, RAID Level 6, or RAID Level 10 volume group. The hot spare adds
another level of redundancy to the storage array. Generally, hot spare drives must have capacities that are
equal to or greater than the used capacity on the drives that they are protecting. Hot spare drives must be of
the same media type and same interface type as the drives that they are protecting.

If a drive fails in the storage array, the hot spare can be substituted automatically for the failed drive without
requiring your intervention. If a hot spare is available when a drive fails, the controller uses redundancy data
to reconstruct the data onto the hot spare. After the failed drive is physically replaced, you can use either of
the following options to restore the data:
When you have replaced the failed drive, the data from the hot spare is copied back to the replacement
drive. This action is called copyback.
You can assign the hot spare as a permanent member of the volume group. Performing the copyback
function is not required for this option.
The availability of tray loss protection and drawer loss protection for a volume group depends on the location
of the drives that comprise the volume group. Tray loss protection and drawer loss protection might be lost
because of a failed drive and the location of the hot spare drive. To make sure that tray loss protection and
drawer loss protection are not affected, you must replace a failed drive to initiate the copyback process.
The storage array automatically selects Data Assurance (DA) capable drives for hot spare coverage of DA-
enabled volumes. Make sure to have DA-capable drives in the storage array for hot spare coverage of DA-
enabled volumes.
Security capable drives provide coverage for both security capable and non-security capable drives. Non-
security capable drives can provide coverage only for other non-security capable drives.
If you do not have a hot spare, you can still replace a failed drive while the storage array is operating. If the
drive is part of a RAID Level 1, RAID Level 3, RAID Level 5, RAID Level 6, or RAID Level 10 volume group,
the controller uses redundancy data to automatically reconstruct the data onto the replacement drive. This
action is called reconstruction.
Channel Protection
In a Fibre Channel environment, channel protection is usually present for any storage array. When the
storage array is cabled correctly, two redundant arbitrated loops (ALs) exist for each drive.
I/O Data Path Protection
Input/output (I/O) data path protection to a redundant controller in a storage array is accomplished with these
multi-path drivers:
The Auto-Volume Transfer (AVT) feature and the Multi-Path I/O (MPIO) driver in the Windows operating
system (OS).
The Multi-Path Proxy (MPP) -based Redundant Dual Active Controller (RDAC) multi-path driver in the
Linux OS.
The Multi-Plexed I/O (MPxIO) driver in the Solaris OS.
The native failover driver using Target Port Group Support (TPGS) in the HP-UX OS version 11.31.
The native failover driver in the VMware OS.
The native failover driver using TPGS in the Mac OS X.
AVT is a built-in feature of the controller firmware that permits ownership of a volume to be transferred to a
second controller if the preferred controller fails. When you use AVT with a multi-path driver, AVT helps to
make sure that an I/O data path is always available for the volumes in the storage array.

If a component, such as a controller, a cable, or an environmental services monitor (ESM), fails, or an error
occurs on the data path to the preferred controller, AVT and the multi-path driver automatically transfer the
volume groups and volumes to the alternate “non-preferred” controller for processing. This failure or error is
called a failover.
Multi-path drivers, such as MPIO, RDAC, and MPxIO, are installed on host computers that access the storage
array and provide I/O path failover. The AVT feature is used specifically for single-port cluster failover. The
AVT feature mode is automatically selected by the host type.
Multi-Path Driver with AVT Enabled
Enabling AVT in your storage array and using it with a host multi-path driver helps to make sure that an I/O
data path is always available for the storage array volumes.
When you create a volume in a storage array where AVT is enabled, a controller must be assigned to own the
volume, called the preferred owner. The preferred controller normally receives the I/O requests to the volume.
If a problem along the data path, such as a component failure, causes an I/O request to fail, the multi-path
driver sends the I/O to the alternate controller.
IMPORTANT You should have the multi-path driver installed at all times. You should always enable the
AVT mode. Set the AVT mode to a single port cluster host type.
After the I/O data path problem is corrected, the preferred controller automatically re-establishes ownership of
the volume as soon as the multi-path driver detects that the path is normal again.
Multi-Path Driver with AVT Disabled
When you disable AVT in your storage array, the I/O data path is still protected as long as a multi-path driver
is installed on each host that is connected to the storage array. However, when an I/O request is sent to a
specified volume, and a problem occurs along the data path to its preferred controller, all volumes on the
preferred controller are transferred to the alternate controller, not just the specified volume.
Target Port Group Support
Target Port Group Support (TPGS) is another multi-path driver that is available on specific combinations of
operating systems and failover drivers that can be present on a host. TPGS provides failover for a storage
array. Failover is an automatic operation that switches the data path for a volume from the preferred controller
to the alternate controller in the case of a hardware failure.
TPGS is part of the ANSI T10 SPC-3 specification. It is implemented in the controller firmware. TPGS is
similar to other multi-pathing options, such as Auto-Volume Transfer (AVT) and Redundant Dual Active
Controller (RDAC), which were developed prior to defining a multi-pathing standard. The advantage of TPGS
is that it is based on the current standard, which allows interoperability with multi-pathing solutions from other
vendors. Interoperability with other multi-pathing solutions simplifies administration of the host.
Each host type uses only one of the multi-path methods: RDAC, AVT, or TPGS.
Load Balancing
Load balancing is the redistribution of read/write requests to maximize throughput between the server and the
storage array. Load balancing is very important in high workload settings or other settings where consistent
service levels are critical. The multi-path driver transparently balances I/O workload without administrator
intervention. Without multi-path software, a server sending I/O requests down several paths might operate
with very heavy workloads on some paths, while other paths are not used efficiently.
SANtricity_10.77 February 2011

The multi-path driver determines which paths to a device are in an active state and can be used for load
balancing. The load-balancing policy uses one of three algorithms: round robin, least queue depth, or least
path weight. Multiple options for setting the load-balancing policies let you optimize I/O performance when
mixed host interfaces are configured. The load-balancing policies that you can choose depend on your
operating system. Load balancing is performed on multiple paths to the same controller, but not across both
controllers.
Operating System Multi-Path Driver Load Balancing Policy
Windows MPIO DSM Round robin, least queue depth,
least path weight
Red Hat Enterprise Linux
(RHEL) RDAC Round robin, least queue depth
SUSE Linux Enterprise
(SLES) RDAC Round robin, least queue depth
Solaris MPxIO Round robin
Round Robin with Subset
The round-robin with subset I/O load-balancing policy routes I/O requests, in rotation, to each available data
path to the controller that owns the volumes. This policy treats all paths to the controller that owns the volume
equally for I/O activity. Paths to the secondary controller are ignored until ownership changes. The basic
assumption for the round-robin policy is that the data paths are equal. With mixed-host support, the data
paths might have different bandwidths or different data transfer speeds.
Least Queue Depth with Subset
The least queue depth with subset policy is also known as the least I/Os policy or the least requests policy.
This policy routes the next I/O request to the data path on the controller that owns the volume that has the
least outstanding I/O requests queued. For this policy, an I/O request is a command in the queue. The type of
command or the number of blocks that are associated with the command is not considered. The least queue
depth with subset policy treats large block requests and small block requests equally. The data path selected
is one of the paths in the path group of the controller that owns the volume.
Least Path Weight with Subset
The least path weight with subset policy assigns a weight factor to each data path to a volume. An I/O request
is routed to the path with the lowest weight value to the controller that owns the volume. If more than one data
path to the volume has the same weight value, the round-robin with subset path selection policy is used to
route I/O requests between the paths with the same weight value.

Introducing the Storage Management Software
The topics in this section describe the basic layout of the SANtricity ES Storage Manager software. The
SANtricity ES Storage Manager software has two windows that provide management functionality and a
graphical representation of your storage array: the Enterprise Management Window (EMW) and the Array
Management Window (AMW).
NOTE The SANtricity ES Storage Manager software is also referred to as the storage management
software.
In general, you will use the following process when using the storage management software. You use the
EMW to add the storage arrays that you want to manage and monitor. Through the EMW, you also receive
alert notifications of errors that affect the storage arrays. If you are notified in the EMW that a storage array
has a non-Optimal status, you can start the AMW for the affected storage array to show detailed information
about the storage array condition.
IMPORTANT Depending on your version of storage management software, the views, menu options,
and functionality might differ from the information presented in this section. For information about available
functionality, refer to the online help topics that are supplied with your version of the storage management
software.
Enterprise Management Window
The Enterprise Management Window (EMW) is the first window to appear when you start the storage
management software. The EMW lets you perform these management tasks:
Discover hosts and storage arrays automatically on your local sub-network.
Manually add and remove hosts and storage arrays.
Monitor the health of the storage arrays and report a high-level status by using the applicable icon.
Configure alert notifications through email or Simple Network Management Protocol (SNMP) and report
events to the configured alert destinations.
Launch the applicable Array Management Window (AMW) for a selected storage array to perform detailed
configuration and management operations.
Run scripts to perform batch management tasks on a particular storage array. For example, scripts might
be run to create new volumes or to download new controller firmware. For more information on running
scripts, refer to the online help topics in the EMW.
Upgrade the controller firmware.
A local configuration file stores all of the information about storage arrays that you have added and any email
destinations or SNMP traps that you have configured.
Parts of the Enterprise Management Window
The Enterprise Management Window (EMW) has these areas that provide options for managing your storage
array.

types of nodes:
Discovered Storage Arrays
Unidentified Storage Arrays
Both the Discovered Storage Arrays node and the Unidentified Storage Arrays node are child nodes of the
storage management station node.
The Discovered Storage Arrays node has child nodes that represent the storage arrays that are currently
managed by the storage management station. Each storage array is labeled with its machine name and is
always present in the Tree view. When storage arrays and hosts with attached storage arrays are added to
the EMW, the storage arrays become child nodes of the Discovered Storage Arrays node.
NOTE If you move the mouse over the storage array node, a tooltip shows the controller’s IP address.
The Unidentified Storage Arrays node shows storage arrays that the storage management station cannot
access because the name or IP address does not exist.

The Logical pane provides a tree-structured view of the logical nodes. Click the plus (+) sign or the minus (-)
sign adjacent to a node to expand or collapse the view. You can right-click a node to open a pop-up menu
that contains the applicable actions for that node.
Nodes in the Logical Pane
The storage array, or root node, has three types of child nodes.
Child Nodes of the
Root Node Description of the Child Nodes
Unconfigured
Capacity This node represents the storage array capacity that is not configured
into a volume group.
Volume Group This node has two types of child nodes:
Volume – This node represents a configured and defined volume.
Multiple Volume nodes can exist under a Volume Group node.
Free Capacity – This node represents a region of capacity that
you can use to create one or more new volumes within the volume
group. Multiple Free Capacity nodes can exist under a Volume
Group node.
NOTE Multiple Unconfigured Capacity nodes appear if your storage array contains drives with different
media types (hard drive or Solid State Disk [SSD]) and different interface types. Each drive type has an
associated Unconfigured Capacity node shown under the Total Unconfigured Capacity node if unassigned
drives are available in the drive tray.
Types of Volumes
These types of volumes appear under the Volume Group node:
Standard volumes is the basic structure that you create in the storage array to store data. A volume is
configured from a volume group with a specific RAID level to meet the software application's needs for
data availability and I/O performance. The operating system sees a volume as one drive.
Primary volumes that participate in a mirror relationship in the primary role. Primary volumes are standard
volumes with a synchronized mirror relationship. The remote secondary volume that is associated with
the primary volume appears as a child node.
SANtricity_10.77 February 2011
LSI Corporation
- 49 -
Secondary volumes appear directly under the Volume Group node when the local storage array contains
this volume.
Mirror repository volumes are special volumes in the storage array that are created as a resource for
each controller in both local storage arrays and remote storage arrays. The controller stores duplicate
information on the mirror repository volume, including information about remote writes that are not yet
written to the secondary volume.
Snapshot repository volumes is a volume in the storage array that is used as a resource for a snapshot
volume.
Snapshot volumes are child nodes of their associated base volume.
Source volumes are standard volumes that participate in a volume copy relationship. Source volumes
are used as the copy source for a target volume. Source volumes accept host I/O requests and store
application data. A source volume can be a standard volume, a snapshot volume, a snapshot base
volume, or a Remote Volume Mirroring primary volume.
Target volumes are standard volumes that participate in a volume copy relationship and contain a copy
of the data from the source volume. Target volumes are read-only and do not accept write requests.
A target volume can be created from a standard volume, the base volume of a snapshot volume, or
a Remote Volume Mirror primary volume. The volume copy overwrites any existing volume data if an
existing volume is used as a target.
Properties Pane
The Properties pane provides detailed information about the component selected in the Logical pane. The
information varies depending on what type of component is selected.
You can view the physical components that are associated with a logical component by selecting the Logical
tab, right-clicking a component, and selecting View Associated Physical Components.
Physical Tab
The Physical tab in the AMW contains two panes: the Physical pane and the Properties pane.
NOTE You can resize either pane by dragging the splitter bar, located between the two panes, to the

The Physical pane provides a view of the hardware components in a storage array, including their status. You
can right-click a hardware component to open a pop-up menu that contains the applicable actions for that
component.
NOTE The orientation of the Physical pane is determined by the actual layout of the storage array. For
example, if the storage array has horizontal drive trays, the storage management software shows horizontal
drive trays in the Physical pane.
The Properties pane provides information for the hardware component that is selected in the Physical pane.
The information in the Properties pane is specific to each hardware component. If you select a controller icon

Managing Multiple Software Versions
When you open the Array Management Window (AMW) to manage a storage array, the version of software
that is appropriate for the version of firmware that the storage array uses is opened. For example, you
manage two storage arrays using this software; one storage array has firmware version 6.14, and the other
has firmware version 7.7x, where x represents a number. When you open the AMW for a particular storage
array, the correct AMW version is used. The storage array with firmware version 6.14 uses version 9.14 of the
storage management software, and the storage array with firmware version 7.7x uses version 10.7x of the
storage management software. You can verify the version that you are currently using by selecting Help >>
About in the AMW.
This bundling of previous versions of the AMW provides the flexibility of upgrading the firmware only on
selected storage arrays instead of having to perform an upgrade on all of the storage arrays at one time.

Configuring the Storage Arrays
The topics in this section describe the methods for configuring storage arrays, including managing security,
and premium features.
For additional information and detailed procedures for the options described in this section, refer to the online
help topics in SANtricity ES Storage Manager.
Volumes and Volume Groups
When you configure a storage array for the first time, you must consider which data protection strategy is
most appropriate for your storage array, together with how the total storage capacity must be organized into
volumes and shared among hosts.
The storage management software identifies several distinct volumes:
Standard volumes
Snapshot volumes
Snapshot repository volumes
Primary volumes
Secondary volumes
Mirror repository volumes
Source volumes
Target volumes
Standard Volumes
A standard volume is a logical structure that is created on a storage array for data storage. A standard volume
is defined from a set of drives called a volume group, which has a defined RAID level and capacity. You
can create a volume from unconfigured capacity, unassigned drives, or Free Capacity nodes on the storage
array. If you have not configured any volumes on the storage array, the only node that is available is the
Unconfigured Capacity node.
Use the Create Volume Wizard to create one or more volumes on the storage array. During the volume
creation process, the wizard prompts you to select the capacity to allocate for the volumes and to define basic
volume parameters and optional advanced volume parameters for the volume.
IMPORTANT The host operating system might have specific limits about how many volumes that the
host can access. You must consider these limits when you create volumes that are used by a particular host.

Volume Groups
A volume group is a set of drives that the controller logically groups together to provide one or more volumes
to an application host. All of the drives in a volume group must have the same media type and interface type.
To create a volume group, you must specify two key parameters: the RAID level and the capacity (how large
you want the volume group to be). You can either select the automatic choices provided by the software or
select the manual method to indicate the specific drives to include in the volume group. Whenever possible,
use the automatic method because the storage management software provides the best selections for drive
groupings.
Volume Group Creation
The Create Volume Group Wizard guides you through the steps to create one or more volume groups in a
storage array and to configure basic volume group parameters and optional volume group parameters.
IMPORTANT The storage management software determines the default initial capacity selections
based on whether you select free capacity, unconfigured capacity, or unassigned drives in the Create Volume
Group Wizard. After the wizard begins, you can change the capacity by defining a new volume capacity.
You can organize available capacity on a storage array by using these types of storage spaces:
Free capacity – Free capacity is unassigned space in a volume group that you can use to create a
volume. When you create a volume from free capacity, an additional volume is created on an existing
volume group.
Unconfigured capacity – Unconfigured capacity is available space on drives of a storage array that
has not been assigned to a volume group. One unconfigured capacity node exists for each type of drive
media and drive interface.
Unassigned drive – An unassigned drive is a drive that is not being used in a volume group or is not
assigned as a hot spare.

Dynamic Capacity Expansion
Dynamic Capacity Expansion (DCE) is a modification operation in the storage management software that
increases the capacity of a volume group. This modification operation allows you to add unassigned drives to
a volume group. Adding unassigned drives increases the free capacity in the volume group. You can use this
free capacity to create additional volumes.
This operation is considered to be dynamic because you have the ability to continually access data in the
volume group throughout the entire operation.
Keep these guidelines in mind when you add unassigned drives to a volume group:
The number of unassigned drives that you can select for a DCE modification operation is limited by the
controller firmware. You can add two unassigned drives at a time. However, after you have completed a
DCE operation, you can add more drives again until the desired capacity is reached.
The existing volumes in the volume group do not increase in size when you add unassigned drives to
expand the free capacity. This operation redistributes existing volume capacity over the larger number of
drives in the volume group.
The unassigned drives that you are adding to the volume group must be of the same media type and
interface type. Mixing different drive types within a single volume group is not permitted. Whenever
possible, select drives that have a capacity equal to the capacities of the current drives in the volume
group.
SANtricity_10.77 February 2011
LSI Corporation
- 59 -
In a RAID Level 1 volume group, you must add two drives to make sure that data redundancy is
configured.
Only security capable drives can be added to a security enabled volume group or a security capable
volume group.
In a volume group that is Data Assurance (DA) capable and contains a DA-enabled volume, you can add
only DA-capable drives.
Register the Volume with the Operating System
After you have created all of your volumes and have assigned mappings, use a volume registration utility,
such as the hot_add utility when using RDAC, to scan the mapped volumes and register the volumes with the
operating system.
You can run the hot_add utility to make sure that the operating system is aware of the newly created volumes.
If available for your operating system, you can run the host-based SMdevices utility to associate the physical
storage array name and the volume name.
Premium Features
The storage management software has the following premium features that provide data-protection
strategies:
SANshare Storage Partitioning
Snapshot Volume
Remote Volume Mirroring (this premium feature is supported only in storage arrays with the Fibre
Channel [FC] host ports)
Volume Copy
SafeStore Drive Security and SafeStore Enterprise Key Manager
SafeStore Data Assurance (DA)
Solid State Disks (SSDs)
SANshare Storage Partitioning
SANshare Storage Partitioning lets hosts with different operating systems share access to a storage array.
Hosts with different operating systems that share access to a storage array are called heterogeneous hosts.
A storage partition is a logical entity that consists of one or more storage array volumes that can be shared
among hosts. To create a storage partition after the total storage capacity has been configured into volumes,
you must define a single host or collection of hosts (or host group) that will access the storage array. Then
you must define a mapping, which lets you specify the host group or the host that will have access to a
particular volume in your storage array.
Based on the premium feature key file purchased, the storage management software can support the
maximum storage partitions shown in this table.

You can define a maximum of 256 volumes per partition (except for the HP-UX 11.23 operating system); this
number is limited to the total number of volumes on your storage array.
Snapshot Volume Premium Feature
The Snapshot Volume premium feature creates a logical point-in-time image of another volume. Snapshot
Volume is a premium feature of the storage management software. You or your storage vendor must enable
this premium feature.
Because the only data blocks that are physically stored in the snapshot repository volume are those that have
changed since the time that the snapshot volume was created, the snapshot volume uses less drive space
than a full physical copy.
Typically, you create a snapshot so that an application (for example, a backup application) can access the
snapshot and read the data; meanwhile, the base volume stays online and is user accessible. When the
backup is completed, the snapshot volume is no longer needed.
You can also create snapshots of a base volume and write data to the snapshot volumes to perform testing
and analysis. Before upgrading your database management system, for example, you can use snapshot
volumes to test different configurations. Then you can use the performance data that is provided by the
storage management software to help you decide how to configure your live database system. The maximum
number of snapshots supported by the storage array is shown in this table.
Storage Array Maximum Number of
Snapshots per Volume Maximum Number of
Snapshots per Storage

CE7900 controller tray Up to 16 Up to 1024
CDE2600 controller-drive tray Up to 16 Up to 256
CDE4900 controller-drive tray Up to 8 Up to 512
Creating Snapshot Volumes
When a snapshot volume is created, the controller suspends I/O activity to the base volume for a few seconds
while it creates a physical volume, called the snapshot repository volume. The snapshot repository volume
stores the snapshot volume metadata and the copy-on-write data.
You can create snapshot volumes by using the Create Snapshot Volume Wizard in the Array Management
Window. The first dialog of the Create Snapshot Volume Wizard lets you select either the simple path or
the advanced path to be followed through the wizard. You can choose the simple path to create a snapshot
volume if the volume group of the base volume has the required amount of free capacity. The simple path lets
you specify the basic parameters for the snapshot volume. The simple path accepts the default settings for
the advanced parameters.
SANtricity_10.77 February 2011
LSI Corporation
- 61 -
NOTE If sufficient free capacity is not available in the volume group of the base volume, the Create
Snapshot Volume Wizard uses the advanced path by default.
In the advanced path, either you can choose to place the snapshot repository volume in another volume
group, or you can use unconfigured capacity in the storage array to create a new volume group. The
advanced path lets you customize the advanced settings for the snapshot volume, such as the full conditions
of the snapshot repository volume and the notification settings.
If you want to create a snapshot volume that performs snapshot operations at a later time or at regularly
occurring intervals, specify a schedule. If you do not specify a schedule, the snapshot operation occurs
immediately.
Scheduling Snapshots
If you want to create a snapshot volume that performs snapshot operations at a later time or at regularly
occurring intervals, add a schedule to the snapshot volume. If you do not add a schedule to the snapshot
volume, the snapshot operation occurs immediately. You can add a schedule when you create a snapshot
volume, or you can add a schedule to an existing snapshot volume. Each snapshot volume can have only one
schedule.
Typical Uses of Scheduling Snapshots
Scheduled backups – For example, an application stores business-critical data in two volumes in the
storage array. You back up this data every work day at 11:00 p.m. To accomplish this type of backup, select
the first volume. Create a schedule that runs once a day on Monday, Tuesday, Wednesday, Thursday, and
Friday. Choose a time between the end of your work day and 11:00 p.m. Select a starting date of today
and no end date. Apply this schedule to the second volume, also. Map the two snapshot volumes to your
backup host, and perform the regular backup procedures. Unmap the two snapshot volumes before the next
scheduled snapshot operation time. If you do not unmap the snapshot volumes, the storage array skips the
next snapshot operation to avoid data corruption.
Rapid recovery – In this example, you back up your data at the end of every work day and keep hourly
snapshots from 8:00 a.m. to 5:00 p.m. If data loss or corruption occurs during the work day, you can recover
the data from the snapshots so that the data loss window is smaller than one hour. To accomplish this type
of recovery, create a schedule that contains a start time of 8:00 a.m. and an end time of 5:00 p.m. Select 10
snapshots per day on Monday, Tuesday, Wednesday, Thursday, and Friday. Select a start date of today and
no end date. Create an end-of-day backup as described in the "Scheduled backups" example.
Guidelines for Creating Schedules
Keep the following guidelines in mind when creating schedules for snapshot volumes:
Either you can create a schedule when you create a snapshot volume, or you can add a schedule to an
existing snapshot volume.
Scheduled snapshot operations do not take place when these conditions occur:
The snapshot volume is mapped.
The storage array is offline or powered off.
The snapshot volume is used as a source volume in a Volume Copy operation, and the status of the
copy operation is Pending or In progress.
If you delete a snapshot volume that has a schedule, the schedule is also deleted.
SANtricity_10.77 February 2011
LSI Corporation
- 62 -
Schedules are stored in the configuration database in the storage array. The management station does
not need to be running the Enterprise Management Window (EMW) or the Array Management Window
(AMW) for the scheduled snapshot operation to occur.
Enabling and Disabling Schedules
You temporarily can suspend scheduled snapshot operations by disabling the schedule. When a schedule
is disabled, the schedule’s timer continues to run, but the scheduled snapshot operations do not occur. This
table shows the icons for scheduled snapshots.
Icon Description
The schedule is enabled. Scheduled snapshots will occur.
The schedule is disabled. Scheduled snapshots will not
occur.
Discontinuing the Use of a Snapshot Volume
As long as a snapshot volume is enabled, storage array performance is affected by the copy-on-write activity
to the associated snapshot repository volume. When you no longer need a snapshot volume, you can disable
it, reuse it, or delete it.
Disable – Stops copy-on-write activity. This option keeps the snapshot volume and snapshot repository
volume intact.
Reuse – Creates a different point-in-time image of the same base volume. This action takes less time to
configure than re-creating the snapshot volume.
Delete – Completely removes the snapshot volume and the associated snapshot repository volume. If
you want to re-enable a snapshot volume, you must re-create it.
Disabling and Restarting Multiple Snapshots
If multiple volumes require regular snapshots for backup purposes, keeping the snapshots enabled might
significantly affect storage array performance. In this situation, you can disable the snapshot function for
multiple volumes and then restart the snapshots for all of the volumes before the next backup is scheduled.
The list of snapshots to be restarted is treated as a single operation. The new point-in-time snapshot images
are created from the previously defined parameters. If an error is encountered on any of the listed snapshots,
none of the snapshots on the list are re-created.
Dynamic Volume Expansion
IMPORTANT Increasing the capacity of a standard volume is only supported on certain operating
systems. If volume capacity is increased on a host operating system that is not supported, the expanded
capacity is unusable, and you cannot restore the original volume capacity.
Dynamic Volume Expansion (DVE) is a modification operation that increases the capacity of standard
volumes or snapshot repository volumes. The increase in capacity can be achieved by using any free
capacity available on the volume group of the standard volume or the snapshot repository volume. Data is
accessible on volume groups, volumes, and drives throughout the entire modification operation.
SANtricity_10.77 February 2011
LSI Corporation
- 63 -
If you receive a warning that the snapshot repository volume is in danger of becoming full, you can use the
DVE modification operation to increase the capacity of the snapshot repository volume.
Increasing the capacity of a snapshot repository volume does not increase the capacity of the associated
snapshot volume. The capacity of the snapshot volume is always based on the capacity of the base volume at
the time that the snapshot volume was created.
Remote Volume Mirroring Premium Feature
The Remote Volume Mirroring premium feature is used for online, real-time data replication between storage
arrays over a remote distance. Storage array controllers manage the mirroring, which is transparent to host
machines and software applications. You create one or more mirrored volume pairs that consist of a primary
volume at the primary site and a secondary volume at a secondary, remote site. After you create the mirror
relationship between the two volumes, the current owner of the primary volume copies all of the data from the
primary volume to the secondary volume. This process is called a full synchronization.
There is a base number of defined mirrors that are allowed for each storage array. You can increase the
number of defined mirrors that are allowed per model with the purchase of an optional feature pack upgrade
key. This table shows the maximum number of defined mirrors to which you can upgrade with a feature pack
upgrade key.
Storage Array Maximum Number of Defined
Mirrors
CE7900 controller tray Up to 128
CDE2600 controller-drive tray Up to 16
CDE4900 controller-drive tray Up to 64
The Remote Volume Mirroring premium feature is not supported in a simplex configuration. You must disable
the Remote Volume Mirroring premium feature before converting a storage array from a duplex configuration
to a simplex configuration. The Remote Volume Mirroring premium feature is supported only in storage arrays
with the Fibre Channel (FC) host ports. The Remote Volume Mirroring premium feature also requires a Fibre
Channel network switch.
ATTENTION Possible loss of data access – You cannot create a mirror relationship if the primary
volume contains unreadable sectors. Furthermore, if an unreadable sector is discovered during a mirroring
operation, the mirror relationship fails.
NOTE Because replication is managed on a per-volume basis, you can mirror individual volumes in a
primary storage array to appropriate secondary volumes in several different remote storage arrays.
Disaster Recovery
The secondary, remote volume is unavailable to secondary host applications while mirroring is in progress. In
the event of a disaster at the primary site, you can fail over to the secondary site. To fail over, perform a role
reversal to promote the secondary volume to a primary volume. Then the recovery host is able to access the
newly promoted volume, and business operations can continue.
SANtricity_10.77 February 2011
LSI Corporation

Data Replication
When the current owner of the primary volume receives a write request from a host, the controller first logs
information about the write to a special volume. This volume is called a mirror repository volume. It writes the
data to the primary volume. Next, the controller initiates a remote write operation to copy the affected data
blocks to the secondary volume at the remote site.
Finally, the controller sends an I/O completion indication back to the host system to confirm that the data was
copied successfully to the secondary storage array. The write mode that you selected when you first created
a remote volume mirror determines when the I/O completion indication is sent to the host system.
The storage management software provides two write modes:
Synchronous – When you select this write mode, any host write requests are written to the primary
volume and then copied to the secondary storage volume. The controller sends an I/O completion
indication to the host system after the copy has been successfully completed.
Asynchronous – When you select this write mode, host write requests are written to the primary volume.
Then the controller sends an I/O completion indication back to the host system before the data has been
successfully copied to the secondary storage array.
When write caching is enabled on either the primary volume or the secondary volume, the I/O completion is
sent when data is in the cache on the side (primary or secondary) where write caching is enabled. When write
caching is disabled on either the primary volume or the secondary volume, the I/O completion is not sent until
the data has been stored to physical media on that side.
Host write requests received by the controller are handled normally. No communication takes place between
the primary storage array and the secondary storage array.
Link Interruptions or Secondary Volume Errors
When processing write requests, the primary controller might be able to write to the primary volume, but a link
interruption prevents communication with the remote secondary controller.
In this case, the remote write cannot complete to the secondary volume. The primary volume and the
secondary volume are no longer appropriately mirrored. The primary controller changes the mirrored pair into
Unsynchronized status and sends an I/O completion to the primary host. The primary host can continue to
write to the primary volume, but remote writes do not take place.
When connectivity is restored between the current owner of the primary volume and the current owner of
the secondary volume, a full synchronization takes place. Only the blocks of data that have changed on the
primary volume during the link interruption are copied to the secondary volume. The mirrored pair changes
from an Unsynchronized state to Mirror Synchronization in Progress status.
The primary controller also marks the mirrored pair as Unsynchronized when a volume error on the secondary
side prevents the remote write from completing. For example, an offline secondary volume or a failed
secondary volume can cause the remote mirror to become unsynchronized. When the volume error is
corrected (the secondary volume is placed online or is recovered to Optimal status), a full synchronization
automatically begins. The mirrored pair then changes to Synchronization in Progress status.
Connectivity and Volume Ownership
A primary controller attempts to communicate only with its matching controller in the secondary storage array.
For example, controller A in the primary storage array attempts communication only with controller A in the
secondary storage array. The controller (A or B) that owns the primary volume determines the current owner
SANtricity_10.77 February 2011
LSI Corporation
- 65 -
of the secondary volume. If the primary volume is owned by controller A on the primary side, the secondary
volume is owned by controller A on the secondary side. If primary controller A cannot communicate with
secondary controller A, controller ownership changes do not take place.
The next remote write processed automatically triggers a matching ownership change on the secondary side
if one of these conditions exists:
When an I/O path error causes a volume ownership change on the primary side
If the storage administrator changes the current owner of the primary volume
For example, a primary volume is owned by controller A, and then you change the controller owner to
controller B. In this case, the next remote write changes the controller owner of the secondary volume from
controller A to controller B. Because controller ownership changes on the secondary side are controlled by
the primary side, they do not require any special intervention by the storage administrator.
Controller Resets and Storage Array Power Cycles
Sometimes a remote write is interrupted by a controller reset or a storage array power cycle before it can be
written to the secondary volume. The storage array controller does not need to perform a full synchronization
of the mirrored volume pair in this case. A controller reset causes a controller ownership change on the
primary side from the preferred controller owner to the alternate controller in the storage array. When a
remote write has been interrupted during a controller reset, the new controller owner on the primary side
reads information stored in a log file in the mirror repository volume of the preferred controller owner. It then
copies the affected data blocks from the primary volume to the secondary volume, eliminating the need for a
full synchronization of the mirrored volumes.
Remote Volume Mirroring Premium Feature Activation
Like other premium features, you enable the Remote Volume Mirroring premium feature by purchasing a
feature key file from your storage supplier. You must enable the premium feature on both the primary storage
array and the secondary storage array.
Unlike other premium features, you also must activate the premium feature after you enable it. To activate
the premium feature, use the Activate Remote Volume Mirroring Wizard in the Array Management Window
(AMW). Each controller in the storage array must have its own mirror repository volume for logging write
information to recover from controller resets and other temporary interruptions. The Activate Remote Volume
Mirroring Wizard guides you to specify the placement of the two mirror repository volumes (on newly created
free capacity or existing free capacity in the storage array).
After you activate the premium feature, one Fibre Channel (FC) host side I/O port on each controller is
solely dedicated to Remote Volume Mirroring operations. Host-initiated I/O operations are not accepted by
the dedicated port. I/O requests received on this port are accepted only from remote controllers that are
participating in Remote Volume Mirroring operations with the controller.
Connectivity Requirements
You must attach dedicated Remote Volume Mirroring ports to a Fibre Channel fabric environment. In addition,
these ports must support the Directory Service interface and the Name Service.
You can use a fabric configuration that is dedicated solely to the Remote Volume Mirroring ports on each
controller. In this case, host systems can connect to the storage arrays using fabric, Fibre Channel Arbitrated
Loop (FC-AL), or point-to-point configurations. These configurations are totally independent of the dedicated
Remote Volume Mirroring fabric.
SANtricity_10.77 February 2011
LSI Corporation
- 66 -
Alternatively, you can use a single Fibre Channel fabric configuration for both the Remote Volume Mirroring
connectivity and for the host I/O paths to the controllers.
The maximum distance between the primary site and the secondary site is 10 km (6.2 miles), using single-
mode fiber gigabit interface converters (GBICs) and optical long-wave GBICs.
Restrictions
These restrictions apply to mirrored volume candidates and storage array mirroring:
RAID level, caching parameters, and segment size can be different on the two mirrored volumes.
The secondary volume must be at least as large as the primary volume.
The only type of volume that can participate in a mirroring relationship is a standard volume. Snapshot
volumes cannot participate.
You can create a snapshot volume by using either a primary volume or a secondary volume as the base
volume.
A primary volume can be a source volume or a target volume in a volume copy. A secondary volume
cannot be a source volume or a target volume unless a role reversal was initiated after the copy has
completed. If a role reversal is initiated during a Copy in Progress status, the copy fails and cannot be
restarted.
A given volume might participate in only one mirror relationship.
Volume Copy Premium Feature
ATTENTION Possible loss of data access – The volume copy operation overwrites existing data on
the target volume and renders the volume read-only to hosts. This option fails all snapshot volumes that are
associated with the target volume, if any exist.
The Volume Copy premium feature copies data from one volume (the source) to another volume (the target)
in a single storage array.
Use the Volume Copy premium feature to perform these tasks:
Copy data from volume groups that use smaller capacity drives to volume groups that use larger capacity
drives.
Create an online copy of data from a volume within a storage array, while still being able to write to the
volume with the copy in progress.
Back up data or restore snapshot volume data to the base volume.
Volume Copy is a premium feature of the storage management software and must be enabled either by you
or your storage vendor.

Volume Copy Features
Data Copying for Greater Access
As your storage requirements for a volume change, use the Volume Copy premium feature to copy data to
a volume in a volume group that uses larger capacity drives within the same storage array. This premium
feature lets you perform these functions:
Move data to larger drives; for example, 73 GB to 146 GB
Change to drives with a higher data transfer rate; for example, 2 Gb/s to 4 Gb/s
Change to drives using new technologies for higher performance
Data Backup
The Volume Copy premium feature lets you back up a volume by copying data from one volume to another
volume in the same storage array. You can use the target volume as a backup for the source volume, for
system testing, or to back up to another device, such as a tape drive.
Snapshot Volume Data Restoration to the Base Volume
If you need to restore data to the base volume from its associated snapshot volume, use the Volume Copy
premium feature to copy data from the snapshot volume to the base volume. You can create a volume copy
of the data on the snapshot volume, and then copy the data to the base volume.
ATTENTION Possible loss of data – If you are using the Windows 2000 operating system or the
Linux operating system, use the Volume Copy premium feature with the Snapshot Volume premium feature to
restore snapshot volume data to the base volume. Otherwise, the source volume and the target volume can
become inaccessible to the host.
Types of Volume Copies
You can perform either an offline volume copy or an online volume copy. To ensure data integrity, all I/O
to the target volume is suspended during either volume copy operation. This suspension occurs because
the state of data on the target volume is inconsistent until the procedure is complete. After the volume copy
operation is complete, the target volume automatically becomes read-only to the hosts.
The offline and online volume copy operations are described as follows.
Offline Copy
An offline copy reads data from the source volume and copies it to a target volume, while suspending all
updates to the source volume with the copy in progress. All updates to the source volume are suspended
to prevent chronological inconsistencies from being created on the target volume. The offline volume copy
relationship is between a source volume and a target volume.
Source volumes that are participating in an offline copy are available for read requests only while a volume
copy has a status of In Progress or Pending. Write requests are allowed after the offline copy has completed.
If the source volume has been formatted with a journaling file system, any attempt to issue a read request to
the source volume might be rejected by the storage array controllers, and an error message might appear.
The journaling file system driver issues a write request before it attempts to issue the read request. The
controller rejects the write request, and the read request might not be issued due to the rejected write request.
This condition might result in an error message appearing, which indicates that the source volume is write
protected. To prevent this issue from occurring, do not attempt to access a source volume that is participating
SANtricity_10.77 February 2011
LSI Corporation
- 68 -
in an offline copy while the volume copy has a status of In Progress. Also, make sure that the Read-Only
attribute for the target volume is disabled after the volume copy has completed to prevent error messages
from appearing.
Online Copy
An online copy creates a point-in-time snapshot copy of a volume within a storage array, while still being
able to write to the volume with the copy in progress. This function is achieved by creating a snapshot of the
volume and using the snapshot as the actual source volume for the copy. The online volume copy relationship
is between a snapshot volume and a target volume. The volume for which the point-in-time image is created
is known as the base volume and must be a standard volume in the storage array.
A snapshot volume and a snapshot repository volume are created during the online copy operation. The
snapshot volume is not an actual volume containing data; rather, it is a reference to the data that was
contained on a volume at a specific time. For each snapshot that is taken, a snapshot repository volume
is created to hold the copy-on-write data for the snapshot. The snapshot repository volume is used only to
manage the snapshot image.
Before a data block on the source volume is modified, the contents of the block to be modified are copied to
the snapshot repository volume for safekeeping. Because the snapshot repository volume stores copies of the
original data in those data blocks, further changes to those data blocks write only to the source volume.
NOTE If the snapshot volume that is used as the copy source is active, the base volume performance
is degraded due to copy-on-write operations. When the copy is complete, the snapshot is disabled, and the
base volume performance is restored. Although the snapshot is disabled, the repository infrastructure and
copy relationship remain intact.
The online copy function is enabled with the Snapshot Volume premium feature. To use the online copy
function, you must enable the Snapshot Volume premium feature by purchasing a feature key file from your
storage vendor.
Components of the Volume Copy Premium Feature
The Volume Copy premium feature includes these components:
Create Copy Wizard, which assists in creating a volume copy.
You can use the Create Copy Wizard to guide you through the following steps in creating a Volume Copy:
Selecting a source volume from a list of available volumes and the type of copy you want to perform
(offline or online)
Selecting a target volume from a list of available volumes
Allocating capacity for the snapshot repository volume for online copy types
Setting the copy priority for the volume copy
When you have completed the wizard dialogs, the volume copy starts, and data is read from the source
volume and written to the target volume. Operation in Progress icons appear on the source volume and the
target volume while the volume copy has a status of In Progress or Pending.
Copy Manager, which monitors volume copies after they have been created.
After you create a volume copy with the Create Copy Wizard, you can monitor the volume copy through the
Copy Manager. You can use the Copy Manager to perform the following actions:
SANtricity_10.77 February 2011
LSI Corporation
- 69 -
Monitor the progress of a volume copy
Stop a volume copy
Re-copy a volume copy
Remove copy pairs
Change target volume permissions
Change copy priority
Keep these guidelines in mind when you create a volume copy.
Failed Controller You must manually change controller
ownership to the alternate controller to allow
the volume copy to complete under all of
these conditions:
The preferred controller of the source
volume fails.
The ownership transfer does not occur
automatically in the failover.
Volume Failover for Online Copy Types Ownership changes affect the base volume
and all of its snapshots. The same controller
should own the base volume, the snapshot
volume, and the snapshot repository volume.
The rules that apply to the base volume for
host-driver-based or controller-based failover
modes also apply to the associated snapshots
and snapshot repository volumes. If a failover
situation occurs, all related volumes change
controller ownership as a group.
Volume Copy and Modification Operations
for Offline Copy Types For offline copy operations, if a modification
operation is running on a source volume or
a target volume, and the volume copy has
a status of In Progress, Pending, or Failed,
the volume copy does not take place. If a
modification operation is running on a source
volume or a target volume after a volume
copy has been created, the modification
operation must complete before the volume
copy can start. If a volume copy has a status
of In Progress, any modification operation
does not take place.
Preferred Controller Ownership During a volume copy, the same controller
must own both the source volume and the
target volume. If both volumes do not have
the same preferred controller when the
volume copy starts, the ownership of the
target volume is automatically transferred to
the preferred controller of the source volume.
When the volume copy is completed or is
stopped, ownership of the target volume
is restored to its preferred controller. If
SANtricity_10.77 February 2011
LSI Corporation
- 70 -
ownership of the source volume is changed
during the volume copy, ownership of the
target volume is also changed.
Failed Volume Copy A volume copy can fail due to these
conditions:
A read error from the source volume
A write error to the target volume
A failure in the storage array that affects
the source volume or the target volume,
such as a remote volume mirror role
reversal
When the volume copy fails, a Needs
Attention icon appears in the Array
Management Window. While a volume copy
has this status, the host has read-only access
to the source volume. Read requests from
and write requests to the target volume do
not take place until the failure is corrected by
using the Recovery Guru.
Volume Copy Status If eight volume copies with a status of In
Progress exist, any subsequent volume
copy will have a status of Pending, which
remains until one of the eight volume copies
completes.
Snapshot Volume A volume copy fails all snapshot volumes
that are associated with the target volume,
if any exist. If you select a base volume of a
snapshot volume, you must disable all of the
snapshot volumes that are associated with
the base volume before you can select it as
a target volume. Otherwise, the base volume
cannot be used as a target volume.
A volume copy overwrites data on the target
volume and automatically makes the target
volume read-only to hosts.
Snapshot Failure If a snapshot volume that is serving as an
online copy fails, the volume copy relationship
is still maintained between the snapshot
volume and the target volume. If the snapshot
failure occurs when the physical copy is in
progress, the status of “Failed” is displayed in
the Copy Manager.
Volume Consistency When using the online volume copy
operation, make sure that the source volume
is in a consistent state. If the source volume is
not consistent, the online volume copy is also
inconsistent. An inconsistent volume might be
unusable for its purpose, such as backup.
SANtricity_10.77 February 2011
LSI Corporation
- 71 -
Copy Failure for Online Copy Types A copy failure terminates the copy-on-write
process for the snapshot volume. If a copy
failure occurs due to a snapshot failure
because of snapshot repository volume
overflow, you can correct the failure by
deleting the copy relationship and re-creating
it.
Restrictions on Volume Copy
These restrictions apply to the source volume, the target volume, and the storage array when performing
volume copy operations.
For an offline volume copy, the source volume is available for read requests only while a volume copy has
a status of In Progress or Pending. Write requests are allowed after the volume copy is completed.
You can use a volume as a target volume in only one volume copy at a time.
The maximum allowable number of volume copies per storage array depends on the number of target
volumes that are available in your storage array.
A storage array can have up to eight volume copies running at any given time.
The capacity of the target volume must be equal to or greater than the capacity of the source volume.
For an offline volume copy, a source volume can be one of the following volumes:
A standard volume
A snapshot volume
A snapshot base volume
A remote volume mirror primary volume
For an online volume copy, a source volume can only be a standard volume.
If the source volume is a primary volume, the capacity of the target volume must be equal to or greater
than the usable capacity of the source volume.
You cannot use the snapshot volume copy until after the online copy operation completes.
You cannot use any of the Snapshot Volume options (Disable, Re-create, Create Copy, Delete,
and Rename) or perform host mapping on a snapshot volume that was created using the online copy
operation in the Create Copy Wizard.
A target volume can be one of these volumes:
A standard volume
A base volume of a disabled snapshot volume or a failed snapshot volume
A remote volume mirror primary volume
NOTE If you choose a base volume of a snapshot volume as your target volume, you must disable
all snapshot volumes that are associated with the base volume before you can select it as a target volume.
Otherwise, you cannot use the base volume as a target volume.
Volumes that have these statuses cannot be used as a source volume or a target volume:
SANtricity_10.77 February 2011
LSI Corporation
- 72 -
A volume that is reserved by the host cannot be selected as a source volume or a target volume
A volume that is in a modification operation
A volume that is the source volume or a target volume in another volume copy operation with a status of
Failed, In Progress, or Pending
A volume with a status of Failed
A volume with a status of Degraded

Window.
SafeStore Drive Security and SafeStore Enterprise Key Manager
SafeStore Drive Security is a premium feature that prevents unauthorized access to the data on a Full Disk
Encryption (FDE) drive that is physically removed from the storage array. Controllers in the storage array
have a security key. Secure drives provide access to data only through a controller that has the correct
security key. SafeStore Drive Security is a premium feature of the storage management software and must be
enabled either by you or your storage vendor.
The SafeStore Drive Security premium feature requires security capable FDE drives. A security capable FDE
drive encrypts data during writes and decrypts data during reads. Each security capable FDE drive has a
unique drive encryption key.
When you create a secure volume group from security capable drives, the drives in that volume group
become security enabled. When a security capable drive has been security enabled, the drive requires the
correct security key from a controller to read or write the data. All of the drives and controllers in a storage
array share the same security key. The shared security key provides read and write access to the drives,
while the drive encryption key on each drive is used to encrypt the data. A security capable drive works like
any other drive until it is security enabled.
Whenever the power is turned off and turned on again, all of the security enabled drives change to a security
locked state. In this state, the data is inaccessible until the correct security key is provided by a controller.
The SafeStore Enterprise Key Manager premium feature integrates external key management products.
You can view the SafeStore Drive Security status of any drive in the storage array. The status information
reports whether the drive is in one of these states:
Security Capable
Secure – Security enabled or security disabled
Read/Write Accessible – Security locked or security unlocked
You can view the SafeStore Drive Security status of any volume group in the storage array. The status
information reports whether the storage array is in one of these states:
Security Capable
Secure
This table interprets the security properties status of a volume group.

Secure – no The volume group is composed
of all FDE drives and is in a Non-
Secure state.
The volume group is not
entirely composed of FDE
drives.
When the SafeStore Drive Security premium feature has been enabled, the Drive Security menu appears in
the Storage Array menu. The Drive Security menu has these options:
Security Key Management
Create Security Key
Change Security Key
Save Security Key
Validate Security Key
Import Security Key File
The Security Key Management option lets you specify how to manage the security key. By default, the
security key is managed locally by the controllers. The controllers generate the security key and save the
security key in the nonvolatile static random access memory (NVSRAM) of the controllers. You can use the
SafeStore Enterprise Key Manager to have an external key management server generate the security key.
NOTE If you have not created a security key for the storage array, the Create Security Key option is
active. If you have created a security key for the storage array, the Create Security Key option is inactive
with a check mark to the left. The Change Security Key option, the Save Security Key option, and the
Validate Security Key option are now active.
The Import Security Key File option is active if there are any security locked drives in the storage array.
When the SafeStore Drive Security premium feature has been enabled, the Secure Drives option appears in
the Volume Group menu. The Secure Drives option is active if these conditions are true:
The selected storage array is not security enabled but is comprised entirely of security capable drives.
The storage array does not contain any snapshot base volumes or snapshot repository volumes.
The volume group is in an Optimal state.
A security key is set up for the storage array.
The Secure Drives option is inactive if the conditions are not true.
The Secure Drives option is inactive with a check mark to the left if the volume group is already security
enabled.
SANtricity_10.77 February 2011
LSI Corporation
- 74 -
You can erase security enabled drives so that you can reuse the drives in another volume group, in another
storage array, or if you are decommissioning the drives. When you erase security enabled drives, you make
sure that the data cannot be read. When all of the drives that you have selected in the Physical pane are
security enabled, and none of the selected drives are part of a volume group, the Secure Erase option
appears in the Drive menu.
The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security premium feature and
should not be confused with the pass phrase that is used to protect copies of a security key. However, it is
good practice to set a storage array password before you create, change, or save a security key or unlock
secure drives.
Using SafeStore Enterprise Key Manager
The SafeStore Enterprise Key Manager premium feature lets you specify how to manage the security
key. You can choose to manage the security key locally by the controllers or externally by an external key
management server. By default, the security key is managed locally by the controllers. The controllers
generate the security key and save the security key in the nonvolatile static random access memory
(NVSRAM) of the controllers. You can also use the SafeStore Enterprise Key Manager to have an external
key management server generate the security key. To change the management method, select Storage
Array >> SafeStore Drive Security >> Security Key Management.
ATTENTION Changing the method of managing the security key from local to external requires
creating and saving a new security key. This action makes any previously saved security key for the storage
array invalid.
NOTE External key management must be enabled for both the source storage array, from which the
key is saved, and any target storage array that imports the key. The key management server used by the
source storage array must be accessible to the target storage array.
A copy of the security key must be kept on some other storage medium for backup, in case of controller
failure or for transfer to another storage array. A pass phrase that you provide is used to encrypt and decrypt
the security key for storage on other media. The storage array password protects a storage array from
potentially destructive operations by unauthorized users. The storage array password is independent from
the SafeStore Drive Security premium feature and should not be confused with the pass phrase that is used
to protect copies of a security key. However, it is good practice to set a storage array password before you
change a security key.
Creating a Security Key
Drives with the full disk encryption technology are security capable. This capability enables the controller
to apply security to every security capable drive in the storage array. The controller firmware creates a key
and activates the drive’s security function, which encrypts data as it enters, and decrypts data as it is read.
Without the key, the data written on a drive is inaccessible and unreadable. A security enabled drive can also
be configured to require a password, PIN, or certificate; however, this function is separate from the encryption
and decryption processes.
The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security premium feature and
should not be confused with the pass phrase that is used to protect copies of a SafeStore Drive Security key.
However, it is good practice to set a storage array password before you create a SafeStore Drive Security
key.
SANtricity_10.77 February 2011
LSI Corporation
- 75 -
After the controller creates the key, the storage array moves from a state of security capable to a state of
security enabled. The security enabled condition requires the drives to obtain a key to access their media. As
an added security measure, when power is applied to the storage array, the drives are all placed in a security
locked state. They are only unlocked during drive initialization with the controller’s key. The security unlocked
state allows the drives to be accessible so that read and write activities can be performed.
Changing a Security Key
A new security key is generated by the controller firmware for these reasons:
You need to change the security key.
You need to change the method of managing the security key from local to external.
ATTENTION Changing the method of managing the security key makes any previously saved security
keys invalid.
The new security key is stored in the nonvolatile static random access memory (NVSRAM) of the controllers.
The new key replaces the previous key. You cannot see the security key directly. A copy of the security key
must be kept on some other storage medium for backup, in case of controller failure or for transfer to another
storage array. A pass phrase that you provide is used to encrypt and decrypt the security key for storage on
other media.
The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security feature and should not
be confused with the pass phrase that is used to protect copies of a SafeStore Drive Security key. However, it
is good practice to set a storage array password before you change a SafeStore Drive Security key.
Saving a Security Key
You save an externally storable copy of the security key when the security key is first created and each time
it is changed. You can create additional storable copies at any time. To save a new copy of the security key,
you must provide a pass phrase. The pass phrase that you choose does not need to match the pass phrase
that was used when the security key was created or last changed. The pass phrase is applied to the particular
copy of the security key that you are saving.
Keep these guidelines in mind when you create a pass phrase:
The pass phrase must be between eight and 32 characters long.
The pass phrase must contain at least one uppercase letter.
The pass phrase must contain at least one lowercase letter.
The pass phrase must contain at least one number.
The pass phrase must contain at least one non-alphanumeric character, for example, <, >, @, or +.
The characters you enter are not readable in the Pass phrase text box.
The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security feature and should not
be confused with the pass phrase that is used to protect copies of a security key. However, it is good practice
to set a storage array password before you save a security key.

Unlocking Secure Drives
You can export a security enabled volume group to move the associated drives to a different storage array.
After you install those drives in the new storage array, you must unlock the drives before data can be read
from or written to the drives. To unlock the drives, you must supply the security key from the original storage
array. The security key on the new storage array will be different and will not be able to unlock the drives.
You must supply the security key from a security key file that was saved on the original storage array. You
must provide the pass phrase that was used to encrypt the security key file to extract the security key from
this file.
The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security feature and should not
be confused with the pass phrase that is used to protect copies of a security key. However, it is good practice
to set a storage array password before you unlock secure drives.
Validating the Security Key
You validate a file in which a security key is stored through the Validate Security Key dialog. To transfer,
archive, or back up the security key, the controller firmware encrypts (or wraps) the security key and stores it
in a file. You must provide a pass phrase and identify the corresponding file to decrypt the file and recover the
security key.
NOTE You can also install the security key from an external key management server. External key
management must be enabled for both the source storage array and the target storage array. The key
management server used by the source storage array must be accessible by the target storage array.
Data can be read from a security enabled drive only if a controller in the storage array provides the correct
security key. If you move security enabled drives from one storage array to another, you must also import
the appropriate security key to the new storage array. Otherwise, the data on the security enabled drives that
were moved is inaccessible.
IMPORTANT After 20 consecutive unsuccessful attempts to validate a security key, you might be
blocked from making further attempts at validation. The Recovery Guru guides you to reset the limit and make
additional attempts. Data on the drives is temporarily inaccessible during the reset procedure.
SafeStore Data Assurance Premium Feature
The SafeStore Data Assurance (DA) premium feature checks for and corrects errors that might occur as
data is moved within the controller, such as from cache to the drive. This checking leads to correction of
write errors and increases data integrity across the entire storage system. DA is implemented using the SCSI
direct-access block-device protection information model. DA creates error-checking information, such as a
cyclic redundancy check (CRC) and appends that information to each block of data. Any errors that might
occur when a block of data is transmitted or stored is then detected and corrected by checking the data with
its error-checking information.
Only certain configurations of hardware, including DA-capable drives, controllers, and host interface cards
(HICs), support the DA premium feature. When you install the DA premium feature on a storage array,
SANtricity ES Storage Manager provides options to use DA with certain operations. For example, you can
create a volume group that includes DA-capable drives and then create a volume within that volume group
that is DA enabled. Other operations that use a DA-enabled volume have options to support the DA premium
feature.

For detailed information about this premium feature, refer to the online help topics in the Array Management
Window.
Solid State Disks
Some controllers and drive trays now support Solid State Disks (SSDs). SSDs are data storage devices that
use solid state memory (flash) to store data persistently. An SSD emulates a conventional hard drive, thus
easily replacing it in any application. SSDs are available with the same interfaces used by hard drives.
The advantages of SSDs over hard drives are:
Faster start up (no spin up)
Faster access to data (no rotational latency or seek time)
Higher I/O operations per second (IOPS)
Higher reliability with fewer moving parts
Lower power usage
Less heat produced and less cooling required
SSD support is a premium feature of the storage management software that must be enabled by either you or
your storage vendor.
Identifying SSDs
You can identify SSDs in the storage management software either by the label “SSD” or this icon.
In addition to drive firmware, SSDs have field-programmable gate array (FPGA) code that might be updated
periodically. An FPGA version is listed in the drive properties, which you can see in the storage management
software by selecting a drive on the Physical tab. Also, SSDs do not have a speed listed in the drive
properties like hard drives do.
Creating Volume Groups
All of the drives in a volume group must have the same media type (hard drive or SSD) and the same
interface type. Hot spare drives must also be of the same drive type as the drives they are protecting.
Wear Life
A flash-based SSD has a limited wear life before individual memory locations can no longer reliably persist
data. The drive continuously monitors itself and reports its wear life status to the controller. Two mechanisms
exist to alert you that an SSD is nearing the end of its useful life: average erase count and spare blocks
remaining. You can find these two pieces of information in the drive properties, which you can see in the
storage management software by selecting a drive on the Physical tab.
The average erase count is reported as a percentage of the rated lifetime. When the average erase count
reaches 80 percent, an event is logged to the Major Event Log (MEL). At this time, you should schedule the
replacement of the SSD. When the average erase count reaches 90 percent, a Needs Attention condition
occurs. At this time, you should replace the SSD as soon as possible.
The spare blocks remaining are reported as a percentage of the total blocks. When the number of spare
blocks remaining falls below 20 percent, an event is logged to the MEL. At this time, you should schedule
the replacement of the SSD. When the number of spare blocks remaining falls below 10 percent, a Needs
Attention condition occurs. At this time, you should replace the SSD as soon as possible.
SANtricity_10.77 February 2011

Write Caching
Write caching will always be enabled for SSDs. Write caching improves performance and extends the life of
the SSD.
Background Media Scans
Background media scans are not necessary for SSDs because of the high reliability of SSDs.
Heterogeneous Hosts
Heterogeneous hosts are hosts with different operating systems that share access to the same storage array.
When you change a host type, you are changing the operating system (OS) for the host adapter’s host port.
To specify different operating systems for attached hosts, you must specify the appropriate host type when
you define the host ports for each host. Host types can be completely different operating systems, or can
be variants of the same operating system. By specifying a host type, you define how the controllers in the
storage array will work with the particular operating system on the hosts that are connected to it.
Password Protection
IMPORTANT Running operations that alter the configuration of your storage array can cause serious
damage, including data loss. Configuring a password for each storage array that you manage prevents
unauthorized access to destructive commands.
For added security, you can configure each storage array with a password to protect it from unauthorized
access. A password protects any options that the controller firmware deems destructive. These options
include any functions that change the state of the storage array, such as creating a volume or modifying the
cache setting.
IMPORTANT If you forget the password, contact your Customer and Technical Support representative.
After the password has been set on the storage array, you are prompted for that password the first time you
attempt an operation in the Array Management Window that can change the state of the storage array, such
as modifying the cache settings. You are asked for the password only once during a single management
session.
For storage arrays with a password and alert notifications configured, any attempts to access the storage
array without the correct password are reported.
The storage management software provides other security features to protect data, including generation
numbering to prevent replay attacks and hashing and encryption to guard against client spoofing and
snooping.
Persistent Reservations Management
ATTENTION Customer and Technical Support representative supervision required – Do not
perform this procedure unless you are supervised by your Customer and Technical Support representative.
Persistent reservation management lets you view and clear volume reservations and associated registrations.
Persistent reservations are configured and managed through the cluster server software and prevent other
hosts from accessing particular volumes.
SANtricity_10.77 February 2011
LSI Corporation
- 79 -
Unlike other types of reservations, a persistent reservation performs these functions:
Reserves access across multiple host ports
Provides various levels of access control
Offers the ability to query the storage array about registered ports and reservations
Optionally, provides for persistence of reservations in the event of a storage array power loss
The storage management software lets you manage persistent reservations by performing these tasks:
Viewing registration and reservation information for all of the volumes in the storage array
Saving detailed information on volume reservations and registrations
Clearing all registrations and reservations for a single volume or for all of the volumes in the storage
array.
HotScale Technology
HotScale™ technology lets you configure, reconfigure, add, or relocate storage array capacity without
interrupting user access to data.
Port bypass technology automatically opens ports and closes ports when drive trays are added to or removed
from your storage array. Fibre Channel loops stay intact so that system integrity is maintained throughout the
process of adding and reconfiguring your storage array.
For more information about using the HotScale technology, contact your Customer and Technical Support
representative.

Maintaining and Monitoring Storage Arrays
The topics in this section describe the methods for maintaining storage arrays, including troubleshooting
storage array problems, recovering from a storage array problem using the Recovery Guru, and configuring
alert notifications using the Event Monitor.
For additional conceptual information and detailed procedures for the options described in this section, refer
to the Learn About Monitoring Storage Arrays online help topic in the Enterprise Management Window.
Storage Array Health
IMPORTANT To receive notification of events for the storage arrays, you must configure alert
notifications in the Enterprise Management Window, and the Event Monitor must be running.
The Enterprise Management Window summarizes the conditions of all of the known storage arrays being
managed. Appropriate status indicators appear in the Tree view on the Devices tab, the Table view on the
Devices tab, and the Health Summary Status area in the lower-left corner of the window. To show the status
bar, select View >> Status Bar.
Background Media Scan
A background media scan is a background process that is performed by the controllers to provide error
detection on the drive media. A background media scan can find media errors before they disrupt normal
drive reads and writes. The background media scan process scans all volume data to make sure that it can
be accessed. The errors are reported to the Event Log.
A background media scan runs on all volumes in the storage array for which it has been enabled. You must
enable the media scan for the entire storage array, and for individual volumes. If you enable a redundancy
check, the background media scan also scans the redundancy data on a RAID Level 1 volume, a RAID Level
3 volume, a RAID Level 5 volume, or a RAID Level 6 volume.
Event Monitor
The Event Monitor runs continuously in the background, monitoring activity on a storage array and checking
for problems. Examples of problems include impending drive failures or failed controllers. If the Event
Monitor detects any problems, it can notify a remote system by using email notifications, Simple Network
Management Protocol (SNMP) trap messages, or both, if the Enterprise Management Window is not running.
The Event Monitor is a client that is bundled with the client software. Install the Event Monitor on a computer
that runs 24 hours a day. The client and the Event Monitor are installed on a storage management station or
a host that is connected to the storage arrays. Even if you choose not to install the Event Monitor, you can still
configure alert notifications on the computer on which the client software is installed.
The following figure shows how the Event Monitor and the Enterprise Management Window client software
send alerts to a remote system. The storage management station contains a file with the name of the storage
array being monitored and the address to which alerts will be sent. The alerts and errors that occur on the
storage array are continuously being monitored by the client software and the Event Monitor. The Event
Monitor continues to monitor the client, even after the client software package is shut down. When an event is
detected, a notification is sent to the remote system.
SANtricity_10.77 February 2011
LSI Corporation
- 81 -
Because the Event Monitor and the Enterprise Management Window share the information to send alert
messages, the Enterprise Management Window has some visual cues to assist in the installation and
synchronization of the Event Monitor.
Using the Event Monitor involves these three key steps:
1. Installing the client software
2. Setting up the alert destinations for the storage arrays that you want to monitor from the Enterprise
Management Window
3. Synchronizing the Enterprise Management Window and the Event Monitor
Alert Notifications
You can configure alert notifications by using the storage management software.
Configuring Alert Notifications
You must configure alert notification settings to receive email notifications or SNMP notifications when an
event occurs in a storage array. The notification summarizes the event and details about the affected storage
array, including these items:
The name of the affected storage array
The host IP address (for an in-band managed storage array)
The host name and ID (shown as out-of-band if the storage array is managed through the Ethernet
connection of each controller)
The event error type related to an Event Log entry
The date and the time when the event occurred
A brief description of the event
SANtricity_10.77 February 2011
LSI Corporation
- 82 -
IMPORTANT To set up alert notifications using SNMP traps, you must copy and compile a
management information base (MIB) file on the designated network management station.
Three key steps are involved in configuring alert notifications:
1. Select a node in the Enterprise Management Window that shows alert notifications for the storage
arrays that you want to monitor. You can select every storage array being managed, every storage array
attached to and managed through a particular host, and individual storage arrays.
2. Configure email destinations, if desired.
3. Configure SNMP trap destinations, if desired. The SNMP trap destination is the IP address or the host
name of a station running an SNMP service, such as a network management station.
Customer Support Alert Notifications
If an event occurs in a storage array, the Enterprise Management Window contains options to configure the
system to send email notifications to a specified customer support group. After the alert notification option
is configured, the email alert notification summarizes the event, provides details about the affected storage
array, and provides customer contact information. For more information about setting up this file, contact your
Customer and Technical Support representative.
Performance Monitor
The Performance Monitor provides visibility into performance activity across your monitored storage devices.
You can use the Performance Monitor to perform these tasks:
View in real time the values of the data collected for a monitored device. This capability helps you to
determine if the device is experiencing any problems.
See a historical view of a monitored device to identify when a problem started or what caused a problem.
Specify various reporting attributes, such as time increments and filtering criteria, to examine performance
trends and to pinpoint the cause of availability and performance issues.
Display data in tabular format (actual values of the collected metrics) or graphical format (primarily as line-
graphs), or export the data to a file.
About Metrics
Metrics are measurements of the data that the Performance Monitor collects from the storage devices that
you monitor. Metrics help to pinpoint problems and define their cause. Metrics define the types of data that
you collect as well as the type of data source from which you collect the data.
Performance Metric Data
You can collect the following metric data:
Total I/Os – Total I/Os performed by this device since the beginning of the polling session.
Read Percentage – The percentage of total I/Os that are read operations for this device. Write
percentage can be calculated as 100 minus this value.
Cache Hit Percentage – The percentage of total I/Os that are processed with data from the cache rather
than requiring a read from drive.
I/O per second – The number of I/O requests serviced per second during the current polling interval (also
called an I/O request rate).
SANtricity_10.77 February 2011

KBs or MBs per second – The transfer rate during the current polling interval. The transfer rate is the
amount of data in kilobytes (Table view) or megabytes (Graphical view) that can be moved through the I/
O data connection in a second (also called throughput).
NOTE A kilobyte is equal to 1024 bytes, and a megabyte is equal to 1024 x 1024 bytes (1,048,576
bytes).
Metric Sources
Metrics define how the Performance Monitor collects data from supported data sources called metric sources.
Metric sources are the aspects of a storage array or a controller that provide data. You can configure the
Performance Monitor to report data from the following metric sources:
Volume
Volume group
Controller
Storage array
You can use the data to create reports, and make tuning decisions based on the data values. If a value is
outside of the desired range or is in an undesired state, you can take action to correct the problem.
NOTE The Performance Monitor reports volume metrics and volume group metrics at the storage array
level, regardless of volume controller ownership changes that might occur during monitoring.
Viewing Performance Data
The Performance Monitor provides both real-time analysis and historical context of performance metrics. The
metrics are available in either of two views:
Table view – In the Table view, the data is displayed in a tabular format. The actual numeric values of the
collected metrics are displayed in a data table.
Graphical view – In the Graphical view, the data is presented with a single x-axis and a single y-axis.
The x-axis represents the time for which you selected to view performance data. The y-axis represents
the metric you selected to view for a particular metric source.
Performance Tuning
The Performance Monitor provides you with data about devices. You use this data to make storage array
tuning decisions, as described in the following table. When performance issues are encountered, tuning is
required to alleviate the issues.
Performance
Metric Data Implications for Performance Tuning
Total I/Os This data is useful for monitoring the I/O activity of a specific controller and a
specific volume, which can help identify possible high-traffic I/O areas.
If the I/O rate is slow on a volume, try increasing the volume group size by
selecting Volume Group >> Add Free Capacity (Drives).
You might notice a disparity in the total I/Os (workload) of controllers. For
example, the workload of one controller is heavy or is increasing over time
while that of the other controller is lighter or more stable. In this case, you

Performance
Metric Data Implications for Performance Tuning
might want to change the controller ownership of one or more volumes to
the controller with the lighter workload. Use the volume total I/O statistics to
determine which volumes to move.
You might want to monitor the workload across the storage array. Look at the
Total I/Os column of the Storage Array Totals row in the Performance Monitor
window. If the workload continues to increase over time while application
performance decreases, you might need to add additional storage arrays. By
adding storage arrays to your enterprise, you can continue to meet application
needs at an acceptable performance level.
Read
Percentage Use the Read Percentage for a volume to determine actual application
behavior. If a low percentage of read activity exists relative to write activity,
you might want to change the RAID level of a volume group from RAID Level 5
to RAID Level 1 to obtain faster performance.
Cache Hit
Percentage A higher cache hit percentage is desirable for optimal application performance.
A positive correlation exists between the cache hit percentage and the I/O
rates.
The cache hit percentage of all of the volumes might be low or trending
downward. This trend might indicate inherent randomness in access patterns.
In addition, at the storage array level or the controller level, this trend might
indicate the need to install more controller cache memory if you do not have
the maximum amount of memory installed.
If an individual volume is experiencing a low cache hit percentage, consider
enabling dynamic cache read prefetch for that volume. Dynamic cache read
prefetch can increase the cache hit percentage for a sequential I/O workload.
KB/s or MB/s The transfer rates of the controller are determined by the application I/O
size and the I/O rate. Generally, small application I/O requests result in a
lower transfer rate but provide a faster I/O rate and shorter response time.
With larger application I/O requests, higher throughput rates are possible.
Understanding your typical application I/O patterns can help you determine the
maximum I/O transfer rates for a specific storage array.
IOPS Factors that affect input/output operations per second (IOPS) include these
items:
Access pattern (random or sequential)
I/O size
RAID level
Segment size
The number of drives in the volume groups or storage array
The higher the cache hit rate, the higher I/O rates will be.
You can see performance improvements caused by changing the segment
size in the IOPS statistics for a volume. Experiment to determine the optimal
segment size, or use the file system size or database block size.
Higher write I/O rates are experienced with write caching enabled compared to
disabled. In deciding whether to enable write caching for an individual volume,
look at the current IOPS and the maximum IOPS. You should see higher rates
SANtricity_10.77 February 2011

Performance
Metric Data Implications for Performance Tuning
for sequential I/O patterns than for random I/O patterns. Regardless of your
I/O pattern, enable write caching to maximize the I/O rate and to shorten the
application response time.
For detailed information about the Performance Monitor, refer to the online help topics in the Array
Management Window.
Viewing Operations in Progress
The Operations in Progress dialog displays all of the long-running operations that are currently running in the
storage array. From this dialog, you cannot interact with the operations. You can only view their progress.
The Operations in Progress dialog remains open until you close it or until you close the Array Management
Window (AMW). You can do other tasks in the AMW while the Operations in Progress dialog is open.
You can view the progress for the following long-running operations:
Dynamic Capacity Expansion (DCE) – Adding capacity to a volume group
Dynamic RAID Migration (DRM) – Changing the RAID level of a volume group
Checking the data redundancy of a volume group
Defragmenting a volume group
Initializing a volume
Dynamic Volume Expansion (DVE) – Adding capacity to a volume
Dynamic Segment Size (DSS) – Changing the segment size of a volume
Reconstruction – Reconstructing data from parity because of unreadable sectors or a failed drive
Copyback – Copying data from a hot spare drive to a new replacement drive
Volume copy
Synchronizing a remote mirror
For detailed information about this feature, refer to the online help topics in the Array Management Window.
Retrieving Trace Buffers
NOTE Use this option only under the guidance of your Customer and Technical Support representative.
You can save trace information to a compressed file. The firmware uses the trace buffers to record
processing, including exception conditions, that might be useful for debugging. Trace information is stored in
the current buffer. You have the option to move the trace information to the flushed buffer after you retrieve
the information. You can retrieve trace buffers without interrupting the operation of the storage array and with
minimal effect on performance.
SANtricity_10.77 February 2011
LSI Corporation
- 86 -
A zip-compressed archive file is stored at the location you specify on the host. The archive contains
trace files from one or both of the controllers in the storage array along with a descriptor file named
trace_description.xml. Each trace file includes a header that identifies the file format to the analysis
software used by the Customer and Technical Support representative. The descriptor file has the following
information:
The World Wide Identifier (WWID) for the storage array.
The serial number of each controller.
A time stamp.
The version number for the controller firmware.
The version number for the management application programming interface (API).
The model ID for the controller board.
The collection status (success or failure) for each controller. If the status is Failed, the reason for failure is
noted, and there is no trace file for the failed controller.
For detailed information about this feature, refer to the online help topics in the Array Management Window.
Upgrading the Controller Firmware
You can upgrade the firmware of the controllers in the storage array by using the storage management
software.
In the process of upgrading the firmware, the firmware file is downloaded from the host to the controller.
After downloading the firmware file, you can upgrade the controllers in the storage array to the new firmware
immediately. Optionally, you can download the firmware file to the controller and upgrade the firmware later at
a more convenient time.
The process of upgrading the firmware after downloading the firmware file is known as activation. During
activation, the existing firmware file in the memory of the controller is replaced with the new firmware file.
The firmware upgrade process requires that the controllers have enough free memory space in which the
firmware file resides until activation.
A version number exists for each firmware file. For example, 06.60.08.00 is a version number for a firmware
file. The first two digits indicate the major revision of the firmware file. The remaining digits indicate the minor
revision of the firmware file. You can view the version number of a firmware file in the Upgrade Controller
Firmware window and the Download Firmware dialog. For more information, refer to the Downloading the
Firmware online help topic in the Enterprise Management Window.
The process of upgrading the firmware can be either a major upgrade or a minor upgrade depending on
the version of the firmware. For example, the process of upgrading the firmware is major if the version of
the current firmware is 06.60.08.00, and you want to upgrade the firmware to version 07.36.12.00. In this
example, the first two digits of the version numbers are different and indicate a major upgrade. In a minor
upgrade, the first two digits of the version numbers are the same. For example, the process of upgrading the
firmware is minor if the version of the current firmware is 06.60.08.00, and you want to upgrade the firmware
to version 06.60.18.00 or any other minor revision of the firmware.
You can use the Enterprise Management Window to perform both major upgrades and minor upgrades. You
can use the Array Management Window to perform minor upgrades only.
The storage management software checks for existing conditions in the storage array before upgrading the
firmware. Any of these conditions in the storage array can prevent the firmware upgrade:
SANtricity_10.77 February 2011
LSI Corporation
- 87 -
An unsupported controller type or controllers of different types that are in the storage array that cannot be
upgraded
One or more failed drives
One or more hot spare drives that are in use
One or more volume groups that are incomplete
Operations, such as defragmenting a volume group, downloading of drive firmware, and others, that are
in progress
Missing volumes that are in the storage array
Controllers that have a status other than Optimal
The storage partitioning database is corrupt
A data validation error occurred in the storage array
The storage array has a Needs Attention status
The storage array is unresponsive, and the storage management software cannot communicate with the
storage array
The Event Log entries are not cleared
You can correct some of these conditions by using the Array Management Window. However, for some of
the conditions, you might need to contact your Customer and Technical Support representative. The storage
management software saves the information about the firmware upgrade process in log files. This action
helps the Customer and Technical Support representative to understand the conditions that prevented the
firmware upgrade.
You can view the status of a storage array in the Status area of the Upgrade Controller Firmware window.
Based on the status, you can select one or more storage arrays for which you want to upgrade the firmware.
You also can use the command line interface (CLI) to download and activate firmware to several storage
arrays. For more information, refer to the About the Command Line Interface online help topic in the
Enterprise Management Window.
Monitoring the Status of the Download
Monitor the progress and completion status of the firmware and NVSRAM download to the controllers to
make sure that errors did not occur. After the Confirm Download dialog is dismissed, the file is transferred
to the storage array. Each controller is sent the new file one at a time. If the file transfer to the first controller
succeeds, then the file is transferred to the second controller. The status of the file transfer and the update to
each participating controller appear in the Upgrade Controller Firmware window.
NOTE When the firmware download successfully completes, a dialog might appear stating that the
current version of the Array Management Window (AMW) is not compatible with the new firmware just
downloaded. If you see this message, dismiss the AMW for the storage array, and open it again after
selecting the storage array in the Enterprise Management Window (EMW) and selecting Tools >> Manage
Storage Array. This action launches a new version of the AMW that is compatible with the new firmware.
The progress and status of optimal controllers that are participating in the download appear. Controllers with
statuses other than Optimal are not represented.

During firmware downloads, the storage management software periodically polls the controller to see if the
download has completed successfully. Sometimes, controller problems occur that keep the download from
occurring. This table shows the results of firmware downloads if a controller is failed.
Task Result
You download new firmware to a storage
array. A controller in the storage array fails,
and you replace the failed controller with a
new one.
After the new controller is installed,
the storage array detects the controller
replacement and synchronizes the firmware
on both controllers.
You download new firmware to a storage
array. A controller in the storage array fails,
but you place the controller back online
(assuming the problem was with something
other than the controller).
The firmware synchronization does not occur.
Problem Notification
IMPORTANT To receive notification of events for the storage arrays, the Enterprise Management
Window (EMW) or the Event Monitor must be running. In addition, you must have configured the alert
notifications in the Enterprise Management Window.
Typically, storage array problems are indicated by using these status notifications:
A Needs Attention status icon appears in several locations:
In the Status bar of the EMW
In the Tree view and the Table view on the Devices tab of the EMW
In the title bar of the Array Management Window (AMW)
In the storage array name and status area above the tabs in the AMW
On the Summary tab, the Logical tab, and the Physical tab in the AMW
Event Log Viewer
The Event Log is a detailed record of events that occur in the storage array. You can use the Event Log as
a supplementary diagnostic tool to the Recovery Guru for tracing storage array events. Always refer to the
Recovery Guru first when you attempt to recover from component failures in the storage array.
The Event Log is stored in reserved areas on the disks in the storage array.
You can perform these actions in the Event Log window:
View and filter the events that are displayed in the Event Log.
Update the display to retrieve any new events.
View detailed information about a selected event.
Save selected Event Log data to a file.
Clear the events in the Event Log.

Glossary
A
Auto-Volume Transfer (AVT)
A feature of the controller firmware that helps to manage each volume in a storage array. When used with
a multi-path driver, AVT helps to make sure that an I/O data path always is available for the volumes in the
storage array.
C
configured capacity
Space on drives in a storage array that has been designated for use in a volume group.
controller
A circuit board and firmware that is located within a controller tray or a controller-drive tray. A controller
manages the input/output (I/O) between the host system and data volumes.
copyback
The process of copying data from a hot spare drive to a replacement drive. When a failed drive has been
physically replaced, a copyback operation automatically occurs from the hot spare drive to the replacement
drive.
D
Default Group
A standard node to which all host groups, hosts, and host ports that do not have any specific mappings are
assigned. The standard node shares access to any volumes that were automatically assigned default logical
unit numbers (LUNs) by the controller firmware during volume creation.
duplex
A disk array system with two active controllers handling host input/output (I/O) requests, referred to as dual-
active controllers.
Dynamic RAID-Level Migration (DRM)
A modification operation that changes the Redundant Array of Independent Disks (RAID) level on a selected
volume group. During the entire modification process, the user can access data on volume groups, volumes,
and drives in the storage management software. The user cannot cancel this operation after it starts.
Dynamic Volume Expansion (DVE)
A modification operation in the storage management software that increases the capacity of a standard
volume or a snapshot repository volume. The operation uses the free capacity available on the volume
group of the standard volume or the snapshot repository volume. This operation is considered to be dynamic
because the user has the ability to continually access data on volume groups, volumes, and drives throughout
the entire operation.

F
Fibre Channel (FC)
A high-speed, serial, storage and networking interface that offers higher performance and greater capacity
and cabling distance. FC offers increased flexibility and scalability for system configurations and simplified
cabling. FC is a host interface that is a channel-network hybrid using an active, intelligent interconnection
scheme (topology) to connect devices over a serial bus. The storage management software uses this
connection between the host (where it is installed) and each controller in the storage array to communicate
with the controllers.
firmware
Low-level program code that is installed into programmable read-only memory (PROM), where it becomes
a permanent part of a computing device. The firmware contains the programming needed for boot and to
implement storage management tasks.
Free Capacity node
A contiguous region of unassigned capacity on a defined volume group. The user assigns free capacity space
to create volumes.
full disk encryption (FDE)
A type of drive technology that can encrypt all data being written to its disk media.
H
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the connection between
the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World
Wide Identifier (WWID) and each HBA host port has a unique WWID.
heterogeneous hosts
Hosts with different operating systems that share access to the same storage array.
host
A computer that is attached to a storage array. A host accesses volumes assigned to it on the storage array.
The access is through the HBA host ports or through the iSCSI host ports on the storage array.
host group
A logical entity that identifies a collection of hosts that share access to the same volumes.
hot spare drive
A spare drive that contains no data and that acts as a standby in case a drive fails in a RAID Level 1, RAID
Level 3, RAID Level 5, or RAID Level 6 volume. The hot spare drive can replace the failed drive in the
volume.

I
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
L
logical unit number (LUN)
The number assigned to the address space that a host uses to access a volume. Each host has its own LUN
address space. Therefore, the same LUN can be used by different hosts to access different volumes.
M
media scan
A background process that runs on all volumes in the storage array for which it has been enabled. A media
scan provides error detection on the drive media. The media scan process scans all volume data to verify that
it can be accessed. Optionally, the media scan process also scans the volume redundancy data.
mirror repository volume
A special volume on the storage array that is created as a resource for each controller in both local storage
arrays and remote storage arrays. The controller stores duplicate information on the mirror repository volume,
including information about remote writes that are not yet written to the secondary volume. The controller
uses the mirrored information to recover from controller resets and from accidental powering-down of storage
arrays.
N
network management station (NMS)
A console with installed network management software that is Simple Network Management Protocol (SNMP)
compliant. The NMS receives and processes information about managed network devices in a form that is
supported by the Management Information Base (MIB) that the NMS uses.
SANtricity ES Storage Manager provides information about critical events, using SNMP trap messages, to the
configured NMS.
node
CONTEXT [Network] [Storage System] An addressable entity connected to an input/output (I/O) bus or
network. Used primarily to refer to computers, storage devices, and storage subsystems. The component of a
node that connects to the bus or network is a port. (The Dictionary of Storage Networking Terminology)
O
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
SANtricity_10.77 February 2011

- 94 -
P
parity
A method that provides complete data redundancy while requiring that only a fraction of the storage capacity
of mirroring. The data and parity blocks are divided between the drives so that if any single drive is removed
(or fails), the data on the drive can be reconstructed. Data is reconstructed by using the data on the remaining
drives. The parity data might exist on only one drive, or the parity data might be distributed between all of the
drives in the Redundant Array of Independent Disks (RAID) group.
premium feature
A feature that is not available in the standard configuration of the storage management software.
primary volume
A standard volume in a mirror relationship that accepts host input/output (I/O) and stores application data.
When the mirror relationship is first created, data from the primary volume is copied in its entirety to the
associated secondary volume. The primary volume contains the original user data in a mirroring relationship.
protocol
CONTEXT [Fibre Channel] [Network] [SCSI] A set of rules for using an interconnect or a network so that
information conveyed on the interconnect can be correctly interpreted by all parties to the communication.
Protocols include such aspects of communication as data representation, data item ordering, message
formats, message and response sequencing rules, block data transmission conventions, timing requirements,
and so forth. (The Dictionary of Storage Networking Terminology, 2004)
R
RAID Level 0
A level of non-redundant Redundant Array of Independent Disks (RAID) in which data is striped across a
volume or volume group. RAID Level 0 provides high input/output (I/O) performance and works well for non-
critical data. All drives are available for storing user data; however, data redundancy does not exist. Data
availability is more at risk than with other RAID levels, because any single drive failure causes data loss and a
volume status of Failed.
RAID Level 0 is not actually RAID unless it is combined with other features to provide data and functional
redundancy, regeneration, and reconstruction, such as RAID Level 1+0 or RAID Level 5+0.
RAID Level 1
A redundant Redundant Array of Independent Disks (RAID) level in which identical copies of data are
maintained on pairs of drives, also known as mirrored pairs. RAID Level 1 uses disk mirroring to make an
exact copy from one drive to another drive.
RAID Level 1 offers the best data availability, but only half of the drives in the volume group are available for
user data. If a single drive fails in a RAID Level 1 volume group, all associated volumes become degraded,
but the mirrored drive allows access to the data. RAID Level 1 can survive multiple drive failures as long
as no more than one failure exists per mirrored pair. If a drive pair fails in a RAID Level 1 volume group, all
associated volumes fail, and all data is lost.
SANtricity_10.77 February 2011
LSI Corporation
- 95 -
RAID Level 3
A high-bandwidth mode Redundant Array of Independent Disks (RAID) level in which both user data and
redundancy data (parity) are striped across the drives. The equivalent of one drive's capacity is used for
redundancy data. RAID Level 3 is good for large data transfers in applications, such as multimedia or medical
imaging, that read and write large sequential blocks of data.
If a single drive fails in a RAID Level 3 volume group, all associated volumes become degraded, but the
redundancy data allows access to the data. If two or more drives fail in a RAID Level 3 volume group, all
associated volumes fail, and all data is lost.
RAID Level 5
A high input/output (I/O) Redundant Array of Independent Disks (RAID) level in which data and redundancy
are striped across a volume group or volume. The equivalent of one drive's capacity is used for redundancy
data. RAID Level 5 is good for multiuser environments, such as database or file system storage, where typical
I/O size is small, and there is a high proportion of read activity.
If a single drive fails in a RAID Level 5 volume group, then all associated volumes become degraded, but the
redundancy data allows access to the data. If two or more drives fail in a RAID Level 5 volume group, then all
associated volumes fail, and all data is lost.
RAID Level 6
A further development of Redundant Array of Independent Disks (RAID) Level 5. RAID Level 6 protects
against simultaneous failure of two member drives by using two independent error correction schemes.
Although RAID Level 6 provides ultra-high data reliability, its write penalty is even more severe than that
of RAID Level 5 because redundant information must be generated and written twice for each application
update. As with RAID Level 4 and RAID Level 5, the write penalty in RAID Level 6 is often mitigated by other
storage technologies, such as caching.
RAID Level 10
A striping and mirroring mode used for high performance.
redundancy (data)
Additional information stored along with user data that enables a controller to reconstruct lost data.
Redundant Array of Independent Disks (RAID) Level 1 uses mirroring for redundancy. RAID Level 3, RAID
Level 5, and RAID Level 6 use redundancy information, sometimes called parity, that is constructed from the
data bytes and is striped along with the data on each drive.
redundancy (hardware)
The use of some hardware components that take over operation when the original hardware component fails.
For example, if one power-fan canister fails in a tray, the second power-fan canister can take over the power
and cooling requirements for the tray.
redundancy check
A scan of volume redundancy data, performed as a part of a background media scan.

Redundant Array of Independent Disks (RAID)
CONTEXT [Storage System] A disk array in which part of the physical storage capacity is used to store
redundant information about user data stored on the remainder of the storage capacity. The redundant
information enables regeneration of user data in the event that one of the array's member disks or the access
path to it fails.
Although it does not conform to this definition, disk striping is often referred to as RAID (RAID Level 0). (The
Dictionary of Storage Networking Terminology)
remote mirror
A mirrored volume pair that consists of a primary volume at the primary site and a secondary volume at a
secondary, remote site.
The secondary, remote volume is unavailable to secondary host applications while mirroring is underway. In
the event of disaster at the primary site, the user can fail over to the secondary site. The failover is done by
performing a role reversal to promote the secondary volume to a primary volume. Then the recovery host will
be able to access the newly promoted volume, and business operations can continue.
remote mirroring
A configuration in which data on one storage array (the primary storage array) is mirrored across a fabric
storage area network (SAN) to a second storage array (the secondary storage array). In the event that the
primary storage array fails, mirrored data at the secondary site is used to reconstruct the data in the volumes.
role reversal
The acts of promoting the secondary volume to be the primary volume of a mirrored volume pair and
demoting the primary volume to be the secondary volume.
S
secondary volume
A standard volume in a mirror relationship that maintains a mirror (or copy) of the data from its associated
primary volume. The secondary volume is available for host read requests only. Write requests to the
secondary volume are not permitted. In the event of a disaster or catastrophic failure of the primary site, the
secondary volume can be promoted to a primary role.
Simple Network Management Protocol (SNMP)
CONTEXT [Network] [Standards] An IETF protocol for monitoring and managing systems and devices in a
network. The data being monitored and managed is defined by a Management Information Base (MIB). The
functions supported by the protocol are the request and retrieval of data, the setting or writing of data, and
traps that signal the occurrence of events. (The Dictionary of Storage Networking Terminology)
simplex
A one-way transmission of data. In simplex communication, communication can only flow in one direction and
cannot flow back the other way.
SANtricity_10.77 February 2011

snapshot repository volume
A volume in the storage array that is made as a resource for a snapshot volume. A snapshot repository
volume holds snapshot volume metadata and copy-on-write data for a specified snapshot volume.
snapshot volume
A point-in-time image of a standard volume. A snapshot is the logical equivalent of a complete physical copy,
but a snapshot is created much more quickly than a physical copy. In addition, a snapshot requires less
unconfigured capacity.
SNMP trap
A notification event issued by a managed device to the network management station when a significant event
occurs. A significant event is not limited to an outage, a fault, or a security violation.
Solid State Disk (SSD)
[Storage System] A disk whose storage capability is provided by solid-state random access or flash memory
rather than magnetic or optical media.
A solid state disk generally offers very high access performance compared to that of rotating magnetic disks,
because it eliminates mechanical seek and rotation time. It may also offer very high data transfer capacity.
Cost per byte of storage, however, is typically higher. (The Dictionary of Storage Networking Terminology)
source volume
A standard volume in a volume copy that accepts host input/output (I/O) and stores application data. When
the volume copy is started, data from the source volume is copied in its entirety to the target volume.
standard volume
A logical component created on a storage array for data storage. Standard volumes are also used when
creating snapshot volumes and remote mirrors.
storage management station
A computer running storage management software that adds, monitors, and manages the storage arrays on a
network.
storage partition
A logical entity that is made up of one or more storage array volumes. These storage array volumes can be
accessed by a single host or can be shared with hosts that can be part of a host group.
striping
CONTEXT [Storage System] Short for data striping; also known as Redundant Array of Independent Disks
(RAID) Level 0 or RAID 0. A mapping technique in which fixed-size consecutive ranges of virtual disk
data addresses are mapped to successive array members in a cyclic pattern. (The Dictionary of Storage
Networking Terminology)

T
target volume
A standard volume in a volume copy that contains a copy of the data from the source volume.
topology
The logical layout of the components of a computer system or network and their interconnections. Topology
deals with questions of what components are directly connected to other components from the standpoint
of being able to communicate. It does not deal with questions of physical location of components or
interconnecting cables. (The Dictionary of Storage Networking Terminology)
U
Unconfigured Capacity node
The capacity present in the storage array from drives that have not been assigned to a volume group.
V
volume
The logical component created for the host to access storage on the storage array. A volume is created from
the capacity available on a volume group. Although a volume might consist of more than one drive, a volume
appears as one logical component to the host.
Volume Copy
A premium feature that copies data from one volume (the source volume) to another volume (the target
volume) within a single storage array.
volume group
A set of drives that is logically grouped and assigned a RAID level. Each volume group created provides the
overall capacity needed to create one or more volumes.
W
write caching
An operation in which data is moved from the host to the cache memory on the controllers. This operation
allows the controllers to copy the data to the drives that comprise a volume. Write caching helps improve data
throughput by storing the data from the host until the controller can access the volume and move the data.

Model 3040 40U Cabinet Site Wiring and Power
The AC power distribution units in the cabinet use common industrial wiring.
SANtricity_10.77 February 2011
LSI Corporation
- 110 -
AC power source – The AC power source must provide the correct voltage, current, and frequency that
are specified on the tray and the serial number label.
Protective ground – Site wiring must include a protective ground connection to the AC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. An external, independent AC power source that is isolated from large switching loads
is recommended to run your storage array. The power going to the AC power distribution boxes and other
components in the cabinet should not have air-conditioning motors, elevator motors, or factory loads on
the same circuit.
Tray power distribution – All units attached to the two individual power strip outlets inside the cabinet
must be wide-ranging between 180 VAC and 264 VAC, 50–60 Hz.
Power interruptions – The cabinet and trays can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Maximum frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the trays in the cabinet automatically perform a power#on
recovery sequence without operator intervention.
Model 3040 40U Cabinet Power Requirements
AC Power Requirements for the Model 3040 40U Cabinet
Parameter Requirement
Nominal voltage 200 VAC to 240 VAC
Frequency 50 Hz to 60 Hz
Nominal current (typical)
Varies depending upon the number and type
of trays that are installed in the cabinet.
10.0 A to 24.0 A
The Model 3040 40U cabinet contains power strips that provide either 48A or 72A of usable power.
The 48A power strips provide up to 48A of usable power through four 12A banks of power. This power is
provided to 21 power outlets that are located in the rear of the cabinet.
The 72A power strips provide up to 72A of usable power through six 12A banks of power. This power is
provided by 24 ICE320 power outlets on each power distribution unit (PDU). The 72A power strips are only
used with the DE6900 drive tray.
ATTENTION Risk of exceeding maximum amperage – You must calculate the load of the devices in
the cabinet to make sure that you do not exceed the 24.0 A maximum. As an example, one controller tray (2.2
A) and four drive trays (1.8 A each) would draw approximately 9.4 A (2.2 + 1.8 + 1.8 + 1.8 + 1.8).

Model 3040 40U Cabinet Grounding
To prevent personal injury or electrostatic discharge (ESD), make sure that the cabinet is correctly grounded.
The ground must have the correct low impedance so that there is no build-up of voltage on any equipment or
on any exposed surfaces. Grounding is especially important to eliminate shock hazards, and to facilitate the
operation of circuit-protective devices.
Use good metal-to-metal bonding techniques, such as bared metal washers and internal star washers or
external star washers. It is not enough to provide ground paths through anodized material or hinges. Never
use sheet metal screws to attach a ground. Refer to the Underwriters Laboratory (UL) safety agency for more
information about the correct grounding techniques to use.
Consider a low impedance grounding and lightning protection when you plan for and install an electrical
system. Your electrical contractor must meet local code requirements and national code requirements when
installing an electrical system.
NOTE Local codes and local standards might have more stringent requirements. Always comply with
local codes.
Model 3040 40U Cabinet Power Distribution
The Model 3040 40U cabinet has two identical AC power distribution units, each of which has a separate
power cord. Depending on your configuration, each AC power distribution unit supports either North American
(USA and Canada) components or worldwide (excluding USA and Canada) components. Each AC power
distribution unit includes these parts:
Two cords per side, NEMA L6-30P or IEC 309
Four circuit breakers per side, 15 A each, for 48A PDUs
Six circuit breakers per side, 15 A each, for 72A PDUs
Twenty IEC 320 power outlets per side, plus an additional outlet for the optional fan tray
NOTE For pluggable equipment, the electrical outlet must be installed near the equipment and must be
easily accessible.

CE7900 Controller Tray Site Wiring and Power
The agency ratings for the CE7900 controller tray are 5.40 A at 100 VAC and 2.25 A at 240 VAC. These
ratings are the overall maximum currents for this system.
The CE7900 controller tray uses wide-ranging redundant power supplies that automatically accommodate
voltages to the AC power source. The power supplies operate within the range of 90 VAC to 264 VAC, at
a minimum frequency of 50 Hz and a maximum frequency of 60 Hz. Voltage levels can fluctuate within the
specified range. The power supplies meet standard voltage requirements for both North American (USA and
Canada) operation and worldwide (except USA and Canada) operation. The power supplies use standard
industrial wiring with line-to-neutral or line-to-line power connections.
Keep this information in mind when you prepare the installation site for the controller tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power
and overload protection. To prevent damage to the controller tray, isolate its power source from large
switching loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The controller tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Maximum frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the controller tray automatically performs a power-on
recovery sequence without operator intervention after the power is restored.
NOTE When a power failure occurs, the controller tray uses battery power to back up the data that is in
cache.
If you are installing a large storage array configuration, you must make sure that you are supplying the correct
AC source voltages and not creating an over-current situation.
When calculating the cabinet’s total power requirements, take the controller tray’s 540 W and divide it by
the cabinet’s input voltage. If you are using 240 VAC, you obtain a maximum current of 2.25 A. Then add
the amperage of each drive tray. If each drive tray uses 1.85 A, then 10 drive trays would use 18.5 A. In this
example, your total storage array would use a rated maximum of 20.75 A.

CE7900 Controller Tray Power Cords and Receptacles
Each CE7900 controller tray is shipped with two AC power cords. Each AC power cord connects one of
the power-fan canisters in the controller tray to an independent, external AC power source, such as a wall
receptacle, or to any acceptable uninterruptible power supply (UPS).

5. Rear of the Cabinet
The optional UPS equipment is either placed external from the cabinet, or it is placed at the bottom of the
cabinet. UPS devices provide a continuous supply of electrical power when utility power is unavailable. Some
UPS equipment can also provide power conditioning to protect your storage array from voltage spikes, line
noise, and undesirable power fluctuations, such as brownout. Contact an electrician to help you select and
install the correct UPS equipment.
The switched-rack power distribution unit (PDU) is also available for some customer-supplied cabinets. These
new PDUs are stand-alone, network-manageable devices that allow programmable control of the power
outlets. This capability enables you to control each outlet independently, manage power sequencing, and
monitor the aggregate current draw through the switched-rack PDU. Additional equipment may be used to
support temperature monitoring as well.
Preparing the Network for the Controllers
If you plan to use Ethernet connections from the storage management station to the controllers, you will use
the out-of-band management method. For this configuration, meet with your network administrator before
you order and install the equipment so that you can prepare for the setup and management of the devices
on the IP network. Each controller uses its Ethernet management ports to connect to the IP network and
communicate with the other devices on the IP network (often requiring a special application to set up the
protocol).

Your network administrator can pre-assign the addresses that you need to manage the communication
between the devices on the IP network. Depending on your storage configuration, you will need the following
addresses:
Up to two network IP addresses for each controller
Up to two subnet mask addresses for each controller
Either two IPv4 addresses (one static and one dynamic) or one IPv6 address for each controller
A Dynamic Host Configuration Protocol (DHCP) address for each controller
If switches are used in your storage environment, you must know if zoning will be used, and how it will be
configured.

CDE2600 Controller-Drive Tray Site Wiring and Power
The CDE2600 controller-drive tray uses wide-ranging, redundant power supplies that automatically
accommodate voltages to the AC power source or the optional –48-VDC power source. The power supplies
meet standard voltage requirements for both North American (USA and Canada) operation and worldwide
(except USA and Canada) operation. The power supplies use standard industrial wiring with line-to-neutral or
line-to-line power connections.
NOTE Power for the optional –48-VDC power configuration is supplied by a centralized DC power plant
instead of the AC power source in the cabinet. Refer to the associated manufacturer’s documentation for
specific DC power source requirements.
Keep this information in mind when you prepare the installation site for the controller-drive tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source or
the optional –48-VDC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the controller-drive tray, isolate its power source from large
switching loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The controller-drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the controller-drive tray automatically performs a power-
on recovery sequence without operator intervention.

DC Power Input
Nominal input voltages for the DC power source are as follows:
Low range: –42 VDC
High range: –60 VDC
The maximum operating current is 21.7 A.
CDE2600 Controller-Drive Tray Power Factor Correction
Power factor correction is applied within the power supply, which maintains the power factor of the controller-
drive tray at greater than 0.95 with nominal input voltage.
CDE2600 Controller-Drive Tray AC Power Cords and Receptacles
Each CDE2600 controller-drive tray is shipped with two AC power cords. Each AC power cord connects one
of the power supplies in a controller-drive tray to an independent, external AC power source, such as a wall
receptacle or a UPS.
If you have a cabinet with internal power cabling, such as a ladder cord, you do not need the AC power cords
that are shipped with the controller-drive tray.
DC power is an option that is available for use with youra controller-drive tray and drive trays. For more
information, see CDE2600 Controller-Drive Tray Optional DC Power Connector Cables and Source Wires.
CDE2600 Controller-Drive Tray Optional DC Power Connector Cables and
Source Wires
The CDE2600 controller-drive tray is shipped with –48-VDC power connector cables if the DC power option
is ordered. The –48-VDC power connector cable plugs into the DC power connector on the rear of the
controller-drive tray. The three source wires on the other end of the power connector cable connect the
controller-drive tray to centralized DC power plant equipment, typically through a bus bar above the cabinet.
WARNING (W12) Risk of electrical shock – This unit has more than one power source. To remove
all power from the unit, all DC MAINS must be disconnected by removing all power connectors (item 4 below)
from the power supplies.

WARNING (W14) Risk of bodily injury – A qualified service person is required to make the DC
power connection according to NEC and CEC guidelines.
Two (or, optionally, four) DC power connector cables are provided with each controller-drive tray. Two DC
power connectors are on the two DC power supplies on the rear of each controller-drive tray if additional
redundancy is required.
NOTE It is not mandatory that you connect the second DC power connection on the DC power supplies
of the controller-drive tray. The second DC power connection is provided for additional redundancy only and
can be connected to a second DC power bus.
Preparing the Network for the Controllers
If you plan to use Ethernet connections from the storage management station to the controllers, you will use
the out-of-band management method. For this configuration, meet with your network administrator before
you order and install the equipment so that you can prepare for the setup and management of the devices
on the IP network. Each controller uses its Ethernet management ports to connect to the IP network and
communicate with the other devices on the IP network (often requiring a special application to set up the
protocol).
Your network administrator can pre-assign the addresses that you need to manage the communication
between the devices on the IP network. Depending on your storage configuration, you will need the following
addresses:
Up to two network IP addresses for each controller
Up to two subnet mask addresses for each controller
Either two IPv4 addresses (one static and one dynamic) or one IPv6 address for each controller
A Dynamic Host Configuration Protocol (DHCP) address for each controller
If switches are used in your storage environment, you must know if zoning will be used, and how it will be
configured.

CDE3994 Controller-Drive Tray Site Wiring and Power
The agency ratings for the CDE3994 controller-drive tray are 6.00 A at 100 VAC and 2.50 A at 240 VAC.
These ratings are the overall maximum AC currents for this system.
The CDE3994 controller-drive tray uses wide-ranging, redundant power supplies that automatically
accommodate voltages to the AC power source or the optional –48-VDC power source. The power supplies
meet standard voltage requirements for both North American (USA and Canada) operation and worldwide
(except USA and Canada) operation. The power supplies use standard industrial wiring with line-to-neutral or
line-to-line power connections.
NOTE Power for the optional –48-VDC power configuration is supplied by a centralized DC power plant
instead of the AC power source in the cabinet. Refer to the associated manufacturer’s documentation for
specific DC power source requirements.
Keep this information in mind when you prepare the installation site for the controller-drive tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source or
the optional –48-VDC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the controller-drive tray, isolate its power source from large
switching loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The controller-drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Maximum frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the controller-drive tray automatically performs a power-
on recovery sequence without operator intervention after the power is restored.
NOTE When a power failure occurs, the controller-drive tray uses battery power to back up the data
that is in cache.
If you are installing a large storage system configuration, you must make sure that you are supplying the
correct AC source voltages, and not creating an over-current situation.

AM1532 Controller-Drive Tray Site Wiring and Power
The AM1532 controller-drive tray uses wide-ranging, redundant power supplies that automatically
accommodate voltages to the AC power source. The power supplies meet standard voltage requirements for
both North American (USA and Canada) operation and worldwide (except USA and Canada) operation. The
power supplies use standard industrial wiring with line-to-neutral or line-to-line power connections.
Keep this information in mind when you prepare the installation site for the controller-drive tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the controller-drive tray, isolate its power source from large
switching loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The controller-drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the controller-drive tray automatically performs a power-
on recovery sequence without operator intervention.

DC Power Input
Nominal input voltages for the DC power source are as follows:
Low range: –36 VDC
High range: –72 VDC
The maximum operating current is 17 A.
AM1532 Controller-Drive Tray Power Factor Correction
Power factor correction is applied within the power supply, which maintains the power factor of the controller-
drive tray at greater than 0.95 with nominal input voltage.
AM1532 Controller-Drive Tray AC Power Cords and Receptacles
Each AM1532 controller-drive tray is shipped with two AC power cords. Each AC power cord connects one
of the power supplies in a controller-drive tray to an independent, external AC power source, such as a wall
receptacle or a UPS.
DC power is an option that is available for use with your controller-drive tray and drive tray. For more
information, see “AM1532 Controller-Drive Tray Optional DC Power Connector Cables and Source Wires.”
If you have a cabinet with internal power cabling, such as a ladder cord, you do not need the AC power cords
that are shipped with the controller-drive tray.
AM1532 Controller-Drive Tray Optional DC Power Connector Cables and
Source Wires
The AM1532 controller-drive tray is shipped with –48-VDC power connector cables if the DC power option
is ordered. The –48-VDC power connector cable plugs into the DC power connector on the rear of the
controller-drive tray. The three source wires on the other end of the power connector cable connect the
controller-drive tray to centralized DC power plant equipment, typically through a bus bar above the cabinet.
WARNING (W12) Risk of electrical shock – This unit has more than one power source. To remove
all power from the unit, all DC MAINS must be disconnected by removing all power connectors (item 4 below)
from the power supplies.

Two DC power connector cables are provided with each controller-drive tray. Two DC power connectors are
on the two DC power supplies on the rear of each controller-drive tray if additional redundancy is required.
NOTE It is not mandatory that you connect the second DC power connection on the DC power supplies
of the controller-drive tray. The second DC power connection is provided for additional redundancy only and
can be connected to a second DC power bus.
Preparing the Network for the Controllers
If you plan to use Ethernet connections from the storage management station to the controllers, you will use
the out-of-band management method. For this configuration, meet with your network administrator before
you order and install the equipment so that you can prepare for the setup and management of the devices
on the IP network. Each controller uses its Ethernet management ports to connect to the IP network and
communicate with the other devices on the IP network (often requiring a special application to set up the
protocol).
Your network administrator can pre-assign the addresses that you need to manage the communication
between the devices on the IP network. Depending on your storage configuration, you will need the following
addresses:
Up to two network IP addresses for each controller
Up to two subnet mask addresses for each controller
Either two IPv4 addresses (one static and one dynamic) or one IPv6 address for each controller
A Dynamic Host Configuration Protocol (DHCP) address for each controller
If switches are used in your storage environment, you must know if zoning will be used, and how it will be
configured.

instead of the AC power source in the cabinet. Refer to the associated manufacturer’s documentation for
specific DC power source requirements.
Keep this information in mind when preparing the installation site for the drive tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source or
the optional –48-VDC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the drive tray, isolate its power source from large switching
loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Maximum frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the drive tray automatically performs a power-on recovery
sequence without operator intervention after the power is restored.

FC4600 Drive Tray Site Wiring and Power
The agency ratings for the FC4600 drive tray are 4.44 A at 100 VAC and 1.85 A at 240 VAC. These ratings
are the overall maximum AC currents for this system.
The FC4600 drive tray uses wide-ranging, redundant power supplies that automatically accommodate
voltages to the AC power source or the optional –48-VDC power source. The power supplies meet standard
voltage requirements for both North American (USA and Canada) operation and worldwide (except USA and
Canada) operation. The power supplies use standard industrial wiring with line-to-neutral or line-to-line power
connections.
NOTE Power for the optional –48-VDC power configuration is supplied by a centralized DC power plant
instead of the AC power source in the cabinet. Refer to the associated manufacturer’s documentation for
specific DC power source requirements.
Keep this information in mind when you prepare the installation site for the drive tray:
Protective ground – Site wiring must include a protective ground connection to the AC power source or
the optional –48-VDC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the drive tray, isolate its power source from large switching
loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Maximum frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the drive tray automatically performs a power-on recovery
sequence without operator intervention after the power is restored.

FC2600 Drive Tray Site Wiring and Power
The FC2600 drive tray uses wide-ranging, redundant power supplies that automatically accommodate
voltages to the AC power source. The power supplies meet standard voltage requirements for both North
American (USA and Canada) operation and worldwide (except USA and Canada) operation. The power
supplies use standard industrial wiring with line-to-neutral or line-to-line power connections.
Protective ground – Site wiring must include a protective ground connection to the AC power source.
NOTE Protective ground is also known as safety ground or chassis ground.
Circuit overloading – Power circuits and associated circuit breakers must provide enough power and
overload protection. To prevent damage to the drive tray, isolate its power source from large switching
loads, such as air-conditioning motors, elevator motors, and factory loads.
Power interruptions – The drive tray can withstand these applied voltage interruptions:
Input transient – 50 percent of the nominal voltage
Duration – One-half cycle
Frequency – Once every 10 seconds
Power failures – If a total power failure occurs, the drive tray automatically performs a power-on recovery
sequence without operator intervention.

Power factor correction is applied within the power supply of each FC2600 drive tray, which maintains the
power factor of the drive tray at greater than 0.99 with nominal input voltage.
FC2600 Drive Tray AC Power Cords and Receptacles
Each FC2600 drive tray is shipped with two AC power cords that are appropriate for use in a typical outlet
in the destination country. Each AC power cord connects one of the power supplies in a drive tray to an
independent, external AC power source, such as a wall receptacle or a UPS.

Things to Know – SFP Transceivers, Fiber-Optic Cables, Copper Cables, and
SAS Cables
The figures in this topic display the fiber-optic cables, copper cables, SFP transceivers., and SAS cables with
a SFF-8088 Connector.
NOTE Your SFP transceivers and cables might look slightly different from the ones shown. The
differences do not affect the performance of the SFP transceivers.
The controller-drive tray supports SAS, Fibre Channel (FC), and iSCSI host connections and SAS drive
connections. FC host connections can operate at 8 Gb/s or at a lower data rate. Ports for 8-Gb/s Fibre
Channel host connections require SFP transceivers designed for this data rate. These SFP transceivers look
similar to other SFP transceivers but are not compatible with other types of connections. SFP transceivers
for 1-Gb/s iSCSI and 10-Gb/s iSCSI connections have a different physical interface for the cable and are not
compatible with other types of connections.
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.

Step 3 – Installing the Host Bus Adapters for the CDE2600
Controller-Drive Tray
Key Terms
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the connection between
the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World
Wide Identifier (WWID) and each HBA host port has a unique WWID.
HBA host port world wide name
A 16-character unique name that is provided for each port on the host bus adapter (HBA).
host bus adapter (HBA)
A physical board that resides in the host. The HBA provides for data transfer between the host and the
controllers in the storage array over the I/O host interface. Each HBA contains one or more physical ports.
Things to Know – Host Bus Adapters and Ethernet Network Interface Cards
The CDE2600 controller-drive tray supports dual 6-Gb/s SAS host connections and optional host interface
cards (HICs) for dual 6-Gb/s SAS, four 1-Gb/s iSCSI, two 10-Gb iSCSI, and four 8-Gb/s FC connections.
The connections on a host must match the type (SAS HBAs for SAS, FC HBAs for FC, or iSCSI HBAs or
Ethernet network interface cards [NICs] for iSCSI) of the HICs to which you connect them. For the best
performance, HBAs for SAS and FC connections should support the highest data rate supported by the
HICs to which they connect.
For maximum hardware redundancy, you must install a minimum of two HBAs (for either SAS or FC host
connections) or two NICs or iSCSI HBAs (for iSCSI host connections) in each host. Using both ports of a
dual-port HBA or a dual-port NIC provides two paths to the storage array but does not ensure redundancy
if an HBA or a NIC fails.
NOTE You can use the Compatibility Matrix to obtain information about the supported models of the
HBAs and their requirements. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer
Partner Program link. Check its Compatibility Matrix to make sure you have an acceptable configuration.
Most of the HBAs, as shipped from the vendor, require updated firmware and software drivers to work
correctly with the storage array. For information about the updates, refer to the website of the HBA
vendor.
Procedure – Installing Host Bus Adapters

NOTE If your operating system is Windows Server 2008 Server Core, you might have additional
installation requirements. Refer to the Microsoft Developers Network (MSDN) for more information about
Windows Server 2008 Server Core. You can access these resources from www.microsoft.com.
3. Install the latest version of the firmware for the HBA. You can find the latest version of the firmware for the
HBA at the HBA vendor website.
IMPORTANT The remaining steps are general steps to obtain the HBA host port World Wide Name
from the HBA BIOS utility. If you have installed the host context agent on all of your hosts, you do not need
to perform these steps. If you are performing these steps, the actual prompts and screens vary depending
on the vendor that provides the HBA. Also, some HBAs have software utilities that you can use to obtain the
world wide name for the port instead of using the BIOS utility.
4. Reboot or start your host.
5. While your host is booting, look for the prompt to access the HBA BIOS utility.
6. Select each HBA to view its HBA host port world wide name.
7. Record the following information for each host and for each HBA connected to the storage array:
The name of each host
The HBAs in each host
The HBA host port world wide name of each port on the HBA

WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.
Procedure – Connecting Host Cables on a CDE2600 Controller-Drive Tray
IMPORTANT Make sure that you have installed the HBAs. Refer to the documentation for the HBAs for
information about how to install the HBA and how to use the supplied configuration utilities.
The type of HICs (SAS, FC, or iSCSI) must match the type of the host bus adapters (HBAs) or network
interface cards (for iSCSI only) to which you connect them.
See the examples in the following section for example cabling patterns.
1. Perform one of these actions:
You are using an FC HIC – Go to step 2.
You are using either a SAS or an iSCSI HIC – Go to step 4. Connections for both SAS and iSCSI
use copper cables with RJ-45 connectors and do not require SFP transceivers.
2. Make sure that the appropriate type of SFP transceiver is inserted into the host channel.
3. If a black, plastic plug is in the SFP transceiver, remove it.
4. Perform one of these actions:
You are using either a SAS or an iSCSI HIC – Starting with the first host channel of each controller,
plug one end of the cable into the host channel.
You are using an FC HIC – Starting with the first host channel of each controller, plug one end of the
cable into the SFP transceiver in the host channel.
The cable is either an Ethernet cable with RJ-45 connectors for 1-Gb/s iSCSI or 6-Gb/s SAS connections,
or a fiber-optic cable for FC connections.
IMPORTANT If Remote Volume Mirroring connections are required, do not connect a host to the
highest numbered host channel.

Step 6 – Installing the Drive Trays for the CDE2600 Controller-
Drive Tray Configurations
Things to Know – General Installation of Drive Trays with the CDE2600
Controller-Drive Tray
IMPORTANT If you are installing the drive tray in a cabinet with other trays, make sure that the
combined power requirements of the drive tray and the other trays do not exceed the power capacity of your
cabinet. For more information, refer to the SANtricity ES Storage Manager Installation DVD.
Special site preparation is not required for any of these drive trays beyond what is normally found in a
computer lab environment.
The power supplies meet standard voltage requirements for both domestic and worldwide operation.
Take these precautions:
Install the drive trays in locations within the cabinet that let you evenly distribute the drive trays
around the controller-drive tray.
Keep as much weight as possible in the bottom half of the cabinet.
WARNING (W15) Risk of bodily injury – An empty tray weighs approximately 56.7 kg (125 lb).
Three persons are required to safely move an empty tray. If the tray is populated with components, a
mechanized lift is required to safely move the tray.
For Additional Information on Drive Tray Installation
Refer to the Storage System Site Preparation Guide on the SANtricity ES Storage Manager Installation DVD
for important considerations about cabinet installation.
Procedure – Installing the DE1600 Drive Tray and the DE5600 Drive Tray
WARNING (W08) Risk of bodily injury –
Two persons are required to safely lift the component.
WARNING (W05) Risk of bodily injury – If the bottom half of the cabinet is empty, do not install
components in the top half of the cabinet. If the top half of the cabinet is too heavy for the bottom half, the
cabinet might fall and cause bodily injury. Always install a component in the lowest available position in the
cabinet.
You can install the drive tray into an industry standard cabinet.
This procedure describes how to install the mounting rails into an industry standard cabinet.

Procedure – Installing Drives for the DE1600 and the DE5600 Drive Trays
In some situations, the drive tray might be delivered without the drives installed. Follow the steps in this
procedure to install the drives. If your drive tray already has drives installed, you can skip this step and go to
either “Things to Know – AC Power Cords” or “Things to Know – DC Power Cords.”
ATTENTION Risk of equipment malfunction – To avoid exceeding the functional and environmental
limits, install only drives that have been provided or approved by the original manufacturer. Drives might be
shipped but not installed. System integrators, resellers, system administrators, or users can install the drives.
NOTE The installation order is from top to bottom and left to right. The installation order is important
because the drives might already contain configuration information that depends upon the correct sequence
of the drives in the tray.
1. Beginning with the first drive slot in the upper-left side of the drive tray, place the drive on the slot guides,
and slide the drive all the way into the slot.
2. Push the drive handle to the right (DE1600 drive tray) or down (DE5600 drive tray) to lock the drive
securely in place.

Step 7 – Connecting the CDE2600 Controller-Drive Tray to the
Drive Trays
Key Terms
drive channel
The path for the transfer of data between the controllers and the drives in the storage array.
Things to Know – CDE2600 Controller-Drive Tray
NOTE On the CDE2600 controller-drive tray, each controller has a pair of levers with handles for
removing the controller from the controller-drive tray. One of these handles on each controller is located next
to a host connector. The close spacing between the handle and the host connector might make it difficult to
remove a cable that is attached to the host connector. If this problem occurs, use a flat-blade screwdriver to
push in the release component on the cable connector.
The CDE2600 controller-drive tray supports both the DE1600 drive tray and the DE5600 drive tray for
expansion.
The maximum number of drive slots in the storage array is 96 (expandable to 192, including the 12 or 24
drive slots in the controller-drive tray. Exceeding 96 (or 192) drive slots makes the storage array invalid.
The controllers cannot perform operations that modify the configuration, such as creating new volumes.
Each controller has one dual-ported SAS expansion connector to connect to the drive trays.
Drive Channel Ports on the CDE2600 Controller-Drive Tray – Rear View
1. Controller Canister
2. SAS Expansion Connector
IMPORTANT To maintain data access in the event of the failure of a controller, an ESM, or a drive
channel, you must connect a drive tray or a string of drive trays to both drive channels on a redundant path
pair.
Things to Know – Drive Trays with the CDE2600 Controller-Drive Tray
Each DE1600 drive tray can contain a maximum of twelve 8.89-cm (3.5-in.) drives.
Each DE5600 drive tray can contain a maximum of twenty-four 6.35-cm (2.5-in.) drives.
The ESMs on the DE1600 drive tray and the DE5600 drive tray contain two sets of In connectors and one
set of Out connectors.

Things to Know – Drive Tray Cabling Configurations – Simplex System
The following figure shows an example of cable configurations from the simplex CDE2600 controller-drive tray
to either a DE1600 drive tray or a DE5600 drive tray. Use this example as a guide to connect cables in your
storage array.
IMPORTANT Configurations for connecting cables in a simplex system do not provide for tray loss
protection. Loss of a drive tray that has a second drive tray connected to it means that you cannot access the
second drive tray.

2. If there is a black, plastic plug in the SAS expansion connector of the controller, remove it.
3. Insert one end of the cable into the SAS expansion connector on the controller in slot A in the controller-
drive tray.
4. Insert the other end of the cable into the connector with an up arrow on the ESM in slot A in the drive tray.
5. Are you adding more drive trays?
IMPORTANT Each ESM in a drive tray has three expansion connectors: two on the left-center of
the ESM and one in the upper-right side. When connecting from an ESM in one drive tray to an ESM in
another drive tray, make sure that you connect the connector on the upper-right to one of the connectors
on the left-center. The following figure shows these arrows on an ESM. If the cable is connected either
between the two left-center ESM connectors or between two upper-right ESM connectors, communication
between the two drive trays is lost.
NOTE It does not matter which of the two left-center ESM connectors you use to connect to the
expansion connector on the far-right side.
Connecting a Cable from One ESM to a Second ESM
Yes – Go to step 6.
No – Go to step 9.
6. In the ESM in the first drive tray, insert one end of the cable into the connector on the far-right side.
7. In the ESM in the next drive tray, insert the other end of the cable into one of the connectors in the left-
center of the ESM.
8. Repeat step 6 through step 7 for each drive tray that you intend to add to the storage array.
SANtricity_10.77 February 2011

- 310 -
9. To each end of the cables, attach a label with this information:
The controller ID (for example, controller A)
The ESM ID (for example, ESM A)
The ESM connector (In or Out)
The drive tray ID
For example, if you are connecting controller A to the In connector on ESM A in drive tray 1, the label on
the controller end of the cable will have this information:
CtA-Dch1, Dm1-ESM_A (left), In – Controller End
The label on the drive tray end of the cable will have this information:
Dm1-ESM_A (left), In, CtrlA
10. If you are installing the controller-drive tray with two controllers, repeat step 2 through step 9 for the
controller in slot B in the controller-drive tray.
IMPORTANT To connect cables for maximum redundancy, the cables attaching controller B must be
connected to the drive trays in the opposite tray order as for controller A. That is, the last drive tray in the
chain from controller A must be the first drive tray in the chain from controller B.

Step 8 – Connecting the Ethernet Cables
Key Terms
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
Things to Know – Connecting Ethernet Cables
ATTENTION Risk of security breach – Connect the Ethernet ports on the controller tray to a private
network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array
might be at risk of being accessed from outside of your network.
These Ethernet connections are intended for out-of-band management and have nothing to do with the
iSCSI host interface cards (HICs), whether 1Gb/s or 10Gb/s.
Ethernet port 2 on each controller is reserved for access by your Customer and Technical Support
representative.
In limited situations in which the storage management station is connected directly to the controller tray,
you must use an Ethernet crossover cable. An Ethernet crossover cable is a special cable that reverses
the pin contacts between the two ends of the cable.
Procedure – Connecting Ethernet Cables
Perform these steps to connect Ethernet cables for out-of-band management. If you use only in-band
management, skip these steps.
1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.
2. Connect the other end to the applicable network connection.
3. Repeat step 1 through step 2 for controller B.

Step 9 – Connecting the Power Cords
The CDE2600 controller-drive tray, the DE1600 drive tray, and the DE5600 drive tray can have either
standard power connections to an AC power source or the optional connections to a DC power source (–48
VDC).
IMPORTANT Make sure that you do not turn on the power to the controller-drive tray or the connected
drive trays until this documentation instructs you to do so. For the correct procedure for turning on the
power, see “Step 10 – Turning on the Power and Checking for Problems in a CDE2600 Controller-Drive Tray
Configuration.”
Things to Know – AC Power Cords
For each AC power connector on the drive tray, make sure that you use a separate power source in the
cabinet. Connecting to independent power sources maintains power redundancy.
To ensure proper cooling and assure availability, the drive trays always use two power supplies.
You can use the power cords shipped with the drive tray with typical outlets used in the destination
country, such as a wall receptacle or an uninterruptible power supply (UPS). These power cords,
however, are not intended for use in most EIA-compliant cabinets.
Things to Know – DC Power Cords
If your drive tray has the DC power option installed, review the following information.
DC Power Cable
1. Supply (negative), brown wire, –48 VDC
2. Return (positive), blue wire
3. Ground, green/yellow wire
4. DC power connector
Each power-fan canister has two DC power connectors. Be sure to use a separate power source for each
power-fan canister in the drive tray to maintain power redundancy. You may, optionally, connect each DC
power connector on the same power-fan canister to a different source for additional redundancy.
A two-pole 30-amp circuit breaker is required between the DC power source and the drive tray for over-
current and short-circuit protection.
WARNING (W14) Risk of bodily injury – A qualified service person is required to make the DC
power connection according to NEC and CEC guidelines.
SANtricity_10.77 February 2011

- 313 -
Procedure – Connecting AC Power Cords
1. Make sure that the circuit breakers in the cabinet are turned off.
2. Make sure that both of the Power switches on the drive trays are turned off.
3. Connect the primary power cords from the cabinet to the external power source.
4. Connect a cabinet interconnect power cord (or power cords specific to your particular cabinet) to the AC
power connector on each power canister in the drive tray.
5. If you are installing other drive trays in the cabinet, connect a power cord to each power canister in the
drive trays.
Procedure – Connecting DC Power Cords
WARNING (W14) Risk of bodily injury – A qualified service person is required to make the DC
power connection according to NEC and CEC guidelines.
IMPORTANT Make sure that you do not turn on power to the drive tray until this guide instructs you to
do so. For the proper procedure for turning on the power, see “Turning on the Power”.
IMPORTANT Before turning off any power switches on a DC-powered drive tray, you must disconnect
the two-pole 20-amp circuit breaker.
1. Disconnect the two-pole 20-amp circuit breaker for the storage array.
2. Make sure that all of the DC power switches on the DC-powered drive tray are turned off.
3. Connect the DC power connector cables to the DC power connectors on the rear of thecontroller tray or
controller-drive tray, and drive trays.
NOTE The three source wires on the DC power connector cable (–48 VDC) connect the drive tray
to centralized DC power plant equipment, typically through a bus bar located above the cabinet.
NOTE It is not mandatory that the second DC power connection on each of the drive tray’s DC
power-fan canisters be connected. The second DC power connection is for additional redundancy only
and may be connected to a second DC power bus.
4. Have a qualified service person connect the other end of the DC power connector cables to the DC power
plant equipment as follows:
a. Connect the brown –48 VDC supply wire to the negative terminal.
b. Connect the blue return wire to the positive terminal.
c. Connect the green/yellow ground wire to the ground terminal.

Step 10 – Turning on the Power and Checking for Problems in a
CDE2600 Controller-Drive Tray Configuration
After you complete this task, you can install the software and perform basic configuration tasks on your
storage array. Continue with the Initial Configuration and Software Installation in these electronic document
topics or through the PDF that is available on the SANtricity ES Storage Manager Installation DVD.
Procedure – Turning On the Power to the Storage Array and Checking for
Problems in a CDE2600 Controller-Drive Tray Configuration
IMPORTANT You must turn on the power to all of the connected drive trays before you turn on the
power for the controller-drive tray. Performing this action makes sure that the controllers recognize each
attached drive tray.
NOTE While the power is being applied to the trays, the LEDs on the front and the rear of the trays
come on and go off intermittently.
1. Turn on both Power switches on each drive tray that is attached to the controller-drive tray. Depending on
your configuration, it can take several minutes for each drive tray to complete the power-on process.
IMPORTANT Before you go to step 2, check the LEDs on the drive trays to verify that the power
was successfully applied to all of the drive trays. Wait 30 seconds after turning on the power to the drive
trays before turning on the power to the controller-drive tray.
2. Turn on both Power switches on the rear of the controller-drive tray. Depending on your configuration, it
can take several minutes for the controller-drive tray to complete the power-on process.
3. Check the LEDs on the front and the rear of the controller-drive tray and the attached drive trays.

If a controller canister or a power-fan canister fails and must be replaced, the Service Action Required (Fault)
LED on that canister comes on to indicate that service action is required. The Service Action Allowed LED
also comes on if it is safe to remove the canister. If data availability dependencies exist or other conditions
that dictate a canister should not be removed, the Service Action Allowed LED stays off.
The Service Action Allowed LED automatically comes on or goes off as conditions change. In most cases,
the Service Action Allowed LED comes on when the Service Action Required (Fault) LED comes on for a
canister.
IMPORTANT If the Service Action Required (Fault) LED comes on but the Service Action Allowed
LED is off for a particular canister, you might need to service another canister first. Check your storage
management software to determine the action that you should take.

Things to Know – SFP Transceivers, Fiber-Optic Cables, Copper Cables, and
SAS Cables
The figures in this topic display the fiber-optic cables, copper cables, SFP transceivers., and SAS cables with
a SFF-8088 Connector.
NOTE Your SFP transceivers and cables might look slightly different from the ones shown. The
differences do not affect the performance of the SFP transceivers.
The controller-drive tray supports SAS, Fibre Channel (FC), and iSCSI host connections and SAS drive
connections. FC host connections can operate at 8 Gb/s or at a lower data rate. Ports for 8-Gb/s Fibre
Channel host connections require SFP transceivers designed for this data rate. These SFP transceivers look
similar to other SFP transceivers but are not compatible with other types of connections. SFP transceivers
for 1-Gb/s iSCSI and 10-Gb/s iSCSI connections have a different physical interface for the cable and are not
compatible with other types of connections.
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a

Controller-Drive Tray
Key Terms
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the connection between
the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World
Wide Identifier (WWID) and each HBA host port has a unique WWID.
HBA host port world wide name
A 16-character unique name that is provided for each port on the host bus adapter (HBA).
host bus adapter (HBA)
A physical board that resides in the host. The HBA provides for data transfer between the host and the
controllers in the storage array over the I/O host interface. Each HBA contains one or more physical ports.
Things to Know – Host Bus Adapters and Ethernet Network Interface Cards
The CDE2600 controller-drive tray supports dual 6-Gb/s SAS host connections and optional host interface
cards (HICs) for dual 6-Gb/s SAS, four 1-Gb/s iSCSI, two 10-Gb iSCSI, and four 8-Gb/s FC connections.
The connections on a host must match the type (SAS HBAs for SAS, FC HBAs for FC, or iSCSI HBAs or
Ethernet network interface cards [NICs] for iSCSI) of the HICs to which you connect them. For the best
performance, HBAs for SAS and FC connections should support the highest data rate supported by the
HICs to which they connect.
For maximum hardware redundancy, you must install a minimum of two HBAs (for either SAS or FC host
connections) or two NICs or iSCSI HBAs (for iSCSI host connections) in each host. Using both ports of a
dual-port HBA or a dual-port NIC provides two paths to the storage array but does not ensure redundancy
if an HBA or a NIC fails.
NOTE You can use the Compatibility Matrix to obtain information about the supported models of the
HBAs and their requirements. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer
Partner Program link. Check its Compatibility Matrix to make sure you have an acceptable configuration.
Most of the HBAs, as shipped from the vendor, require updated firmware and software drivers to work
correctly with the storage array. For information about the updates, refer to the website of the HBA
vendor.
Procedure – Installing Host Bus Adapters

Windows Server 2008 Server Core. You can access these resources from www.microsoft.com.
3. Install the latest version of the firmware for the HBA. You can find the latest version of the firmware for the
HBA at the HBA vendor website.
IMPORTANT The remaining steps are general steps to obtain the HBA host port World Wide Name
from the HBA BIOS utility. If you have installed the host context agent on all of your hosts, you do not need
to perform these steps. If you are performing these steps, the actual prompts and screens vary depending
on the vendor that provides the HBA. Also, some HBAs have software utilities that you can use to obtain the
world wide name for the port instead of using the BIOS utility.
4. Reboot or start your host.
5. While your host is booting, look for the prompt to access the HBA BIOS utility.
6. Select each HBA to view its HBA host port world wide name.
7. Record the following information for each host and for each HBA connected to the storage array:
The name of each host
The HBAs in each host
The HBA host port world wide name of each port on the HBA

topology
The logical layout of the components of a computer system or network and their interconnections. Topology
deals with questions of what components are directly connected to other components from the standpoint
of being able to communicate. It does not deal with questions of physical location of components or
interconnecting cables. (The Dictionary of Storage Networking Terminology)
Things to Know – Host Channels on the CDE2600-60 Controller-Drive Tray
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when you handle tray components.
Each controller has from two to six host ports.
Two of the host ports are standard and support 6-Gb/s SAS data rates.
Two to four of the host ports are optional, and, if present, are located on a host interface card (HIC). The
following types of HICs are supported:
NOTE In configurations where a HIC does not exist, the space is covered with a blank faceplate.
Two SAS connectors at 6-Gb/s
Four iSCSI connectors at 1-Gb/s
Two iSCSI connectors at 10-Gb/s
Four FC connectors at 8-Gb/s

2. Host Interface Card (HIC) Connectors (SAS in this Example)
3. SAS Expansion Connector
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.
Procedure – Connecting Host Cables on a CDE2600-60 Controller-Drive Tray
IMPORTANT Make sure that you have installed the HBAs. Refer to the documentation for the HBAs for
information about how to install the HBA and how to use the supplied configuration utilities.
The type of HICs (SAS, FC, or iSCSI) must match the type of the host bus adapters (HBAs) or network
interface cards (for iSCSI only) to which you connect them.
See the examples in the following section for example cabling patterns.
1. Perform one of these actions:
You are using an FC HIC – Go to step 2.
You are using either a SAS or an iSCSI HIC – Go to step 4. Connections for both SAS and iSCSI
use copper cables with RJ-45 connectors and do not require SFP transceivers.
2. Make sure that the appropriate type of SFP transceiver is inserted into the host channel.
3. If a black, plastic plug is in the SFP transceiver, remove it.
4. Perform one of these actions:
You are using either a SAS or an iSCSI HIC – Starting with the first host channel of each controller,
plug one end of the cable into the host channel.
You are using an FC HIC – Starting with the first host channel of each controller, plug one end of the
cable into the SFP transceiver in the host channel.
The cable is either an Ethernet cable with RJ-45 connectors for 1-Gb/s iSCSI or 6-Gb/s SAS connections,
or a fiber-optic cable for FC connections.
IMPORTANT If Remote Volume Mirroring connections are required, do not connect a host to the
highest numbered host channel.

Steps to Install – Drives on the DE6600 Drive Tray
The DE6600 drive tray is shipped with the drive drawers installed, but the drives are not installed. Follow the
steps in this procedure to install the drives.
ATTENTION Risk of equipment malfunction – To avoid exceeding the functional and environmental
limits, install only drives that have been provided or approved by the original manufacturer. Drives might be
shipped but not installed. System integrators, resellers, system administrators, or users can install the drives.
IMPORTANT The installation order within each drawer is from left to right in rows. Slots 1, 4, 7 and
10 must have a drive installed in these locations to make sure there is sufficient air flow to the drives. To
verify these slots, consult the overlay on the front of each of the five drive drawers. Make sure the four drives
in each row are adjacent to each other. The long edge of each drive should touch the drive next to it. To
maintain a uniform airflow across all drive drawers, the drive tray must be configured with a minimum of 20
drives, with four drives in the front row of each of the five drive drawers.

Key Terms
drive channel
The path for the transfer of data between the controllers and the drives in the storage array.
Things to Know – CDE2600-60 Controller-Drive Tray
NOTE On the CDE2600-60 controller-drive tray, each controller has a pair of levers with handles for
removing the controller from the controller-drive tray. One of these handles on each controller is located next
to a host connector. The close spacing between the handle and the host connector might make it difficult to
remove a cable that is attached to the host connector. If this problem occurs, use a flat-blade screwdriver to
push in the release component on the cable connector.
The CDE2600-60 controller-drive tray supports the DE6600 drive tray for expansion.
The maximum number of drive slots in the storage array is 180 drive slots, including up to 60 drive slots in
the controller-drive tray. Exceeding 180 drive slots makes the storage array invalid. The controllers cannot
perform operations that modify the configuration, such as creating new volumes.
Each controller has one dual-ported SAS expansion connector to connect to the drive trays.

IMPORTANT Each ESM in a drive tray has three expansion connectors: two on the left-center of
the ESM and one in the upper-right side. When connecting from an ESM in one drive tray to an ESM in
another drive tray, make sure that you connect the connector on the upper-right to one of the connectors
on the left-center. The following figure shows these arrows on an ESM. If the cable is connected either
between the two left-center ESM connectors or between two upper-right ESM connectors, communication
between the two drive trays is lost.
NOTE It does not matter which of the two left-center ESM connectors you use to connect to the
expansion connector on the far-right side.
Connecting a Cable from One ESM to a Second ESM
Yes – Go to step 6.
No – Go to step 9.
6. In the ESM in the first drive tray, insert one end of the cable into the connector on the far-right side.
7. In the ESM in the next drive tray, insert the other end of the cable into one of the connectors in the left-
center of the ESM.
8. Repeat step 6 through step 7 for each drive tray that you intend to add to the storage array.
9. To each end of the cables, attach a label with this information:
The controller ID (for example, controller A)
The ESM ID (for example, ESM A)
The ESM connector (In or Out)
The drive tray ID
For example, if you are connecting controller A to the In connector on ESM A in drive tray 1, the label on
the controller end of the cable will have this information:
CtA-Dch1, Dm1-ESM_A (left), In – Controller End
The label on the drive tray end of the cable will have this information:
Dm1-ESM_A (left), In, CtrlA
10. If you are installing the controller-drive tray with two controllers, repeat step 2 through step 9 for the
controller in slot B in the controller-drive tray.

Step 8 – Connecting the Ethernet Cables
Key Terms
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
Things to Know – Connecting Ethernet Cables
ATTENTION Risk of security breach – Connect the Ethernet ports on the controller tray to a private
network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array
might be at risk of being accessed from outside of your network.
These Ethernet connections are intended for out-of-band management and have nothing to do with the
iSCSI host interface cards (HICs), whether 1Gb/s or 10Gb/s.
Ethernet port 2 on each controller is reserved for access by your Customer and Technical Support
representative.
In limited situations in which the storage management station is connected directly to the controller tray,
you must use an Ethernet crossover cable. An Ethernet crossover cable is a special cable that reverses
the pin contacts between the two ends of the cable.
Procedure – Connecting Ethernet Cables
Perform these steps to connect Ethernet cables for out-of-band management. If you use only in-band
management, skip these steps.
1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.
2. Connect the other end to the applicable network connection.
3. Repeat step 1 through step 2 for controller B.

Step 9 – Connecting the Power Cords
The CDE2600 controller-drive tray, the DE1600 drive tray, and the DE5600 drive tray can have either
standard power connections to an AC power source or the optional connections to a DC power source (–48
VDC).
IMPORTANT Make sure that you do not turn on the power to the controller-drive tray or the connected
drive trays until this documentation instructs you to do so. For the correct procedure for turning on the power,
see “.”
Things to Know – AC Power Cords
For each AC power connector on the drive tray, make sure that you use a separate power source in the
cabinet. Connecting to independent power sources maintains power redundancy.
To ensure proper cooling and assure availability, the drive trays always use two power supplies.
You can use the power cords shipped with the drive tray with typical outlets used in the destination
country, such as a wall receptacle or an uninterruptible power supply (UPS). These power cords,
however, are not intended for use in most EIA-compliant cabinets.
Procedure – Connecting AC Power Cords
1. Make sure that the circuit breakers in the cabinet are turned off.
2. Make sure that both of the Power switches on the drive trays are turned off.
3. Connect the primary power cords from the cabinet to the external power source.
4. Connect a cabinet interconnect power cord (or power cords specific to your particular cabinet) to the AC
power connector on each power canister in the drive tray.
5. If you are installing other drive trays in the cabinet, connect a power cord to each power canister in the
drive trays.

Step 10 – Turning on the Power and Checking for Problems in a
CDE2600-60 Controller-Drive Tray Configuration
Once you complete this task, you can install the begin to install the software and perform basic configuration
tasks on your storage array. Continue with the Initial Configuration and Software Installation in these
electronic document topics or through the PDF that is available on the SANtricity ES Storage Manager
Installation DVD.
Procedure – Turning On the Power to the Storage Array and Checking for
Problems in a CDE2600-60 Controller-Drive Tray Configuration
IMPORTANT You must turn on the power to all of the connected drive trays before you turn on the
power for the controller-drive tray. Performing this action makes sure that the controllers recognize each
attached drive tray.
NOTE While the power is being applied to the trays, the LEDs on the front and the rear of the trays
come on and go off intermittently.
1. Turn on both Power switches on each drive tray that is attached to the controller-drive tray. Depending on
your configuration, it can take several minutes for each drive tray to complete the power-on process.
IMPORTANT Before you go to step 2, check the LEDs on the drive trays to verify that the power
was successfully applied to all of the drive trays. Wait 30 seconds after turning on the power to the drive
trays before turning on the power to the controller-drive tray.
2. Turn on both Power switches on the rear of the controller-drive tray. Depending on your configuration, it
can take several minutes for the controller-drive tray to complete the power-on process.
3. Check the LEDs on the front and the rear of the controller-drive tray and the attached drive trays.
4. If you see any amber LEDs, make a note of their location.

If a controller canister or a power-fan canister fails and must be replaced, the Service Action Required (Fault)
LED on that canister comes on to indicate that service action is required. The Service Action Allowed LED
also comes on if it is safe to remove the canister. If data availability dependencies exist or other conditions
that dictate a canister should not be removed, the Service Action Allowed LED stays off.
The Service Action Allowed LED automatically comes on or goes off as conditions change. In most cases,
the Service Action Allowed LED comes on when the Service Action Required (Fault) LED comes on for a
canister.
IMPORTANT If the Service Action Required (Fault) LED comes on but the Service Action Allowed
LED is off for a particular canister, you might need to service another canister first. Check your storage
management software to determine the action that you should take.
Things to Know – Sequence Code Definitions for the CDE2600-60 Controller-

Step 1 – Preparing for a CE7900 Controller Tray Installation
The CE7900 storage array consists of a CE7900 controller tray and one or more drive trays in a cabinet. Use
this initial setup guide to install the CE7900 controller tray. This document includes instructions for installing
the DE6900 drive trays or FC4600 drive trays.
Key Terms
storage array
A collection of both physical components and logical components for storing data. Physical components
include drives, controllers, fans, and power supplies. Logical components include volume groups and
volumes. These components are managed by the storage management software.
controller tray
One tray with one or two controllers. The controller tray also contains power supplies, fans, and other
supporting components. The controller tray provides the interface between a host and a storage array. A
controller tray does not have drives for storing data.
controller
A circuit board and firmware that is located within a controller tray or a controller-drive tray. A controller
manages the input/output (I/O) between the host system and data volumes.
drive tray
One tray with drives, one or two environmental services monitors (ESMs), power supplies, and fans. A drive
tray does not contain controllers.
environmental services monitor (ESM)
A canister in the drive tray that monitors the status of the components. An ESM also serves as the connection
point to transfer data between the drive tray and the controller.
Small Form-factor Pluggable (SFP) transceiver
A component that enables Fibre Channel duplex communication between storage array devices. SFP
transceivers can be inserted into host bus adapters (HBAs), controllers, and environmental services monitors
(ESMs). SFP transceivers can support either copper cables (the SFP transceiver is integrated with the cable)
or fiber-optic cables (the SFP transceiver is a separate component from the fiber-optic cable).
Gathering Items
Before you start installing the controller tray, you must have installed the cabinet in which the controller tray
will be mounted.
Use the tables in this section to verify that you have all of the necessary items to install the controller tray.

Step 3 – Installing the Host Bus Adapters for the CE7900
Controller Tray
Key Terms
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the connection between
the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World
Wide Identifier (WWID) and each HBA host port has a unique WWID.
HBA host port world wide name
A 16-character unique name that is provided for each port on the host bus adapter (HBA).
host bus adapter (HBA)
A physical board that resides in the host. The HBA provides for data transfer between the host and the
controllers in the storage array over the I/O host interface. Each HBA contains one or more physical ports.
Things to Know – Host Adapters
Host connections might be Fibre Channel connections through host bus adapters (HBAs), InfiniBand
connections through host channel adapters (HCAs), or iSCSI connections through Ethernet adapters. The
CE7900 controller tray can have host interface cards (HICs) for any of these types of connections. The type of
a host adapter installed in a host must match the type of the HIC to which it connects. When host connections
are made through switches, the switches must support the speed and protocol of the connection.
For maximum hardware redundancy, you must install a minimum of two host adapters in each host. Dual-
ported host adapters provide two paths into the storage array but do not ensure redundancy if the entire
host adapter fails.
Most of the host adapters, as shipped from the vendor, require updated firmware and software drivers
to work correctly with the storage array. For information about the updates, refer to the web site of the
vendor for the host adapter.
NOTE You can use the Compatibility Matrix to obtain information about the supported models of the
host adapters and their requirements. Go to the web page at http://www.lsi.com/CompatibilityMatrix/. In the
search form, choose Host Adapter from the Product drop-down list. Use the search form to make sure you
have an acceptable configuration.
For best performance, cable an 8-Gb/s Fibre Channel HIC to an 8-Gb/s HBA. If the data rate for the HBA
is lower, the data transfer will occur at the lower rate. For instance, if you cable an 8-Gb/s Fibre Channel
HIC to a 4-Gb/s HBA, the data transfer rate is 4 Gb/s.
You cannot mix InfiniBand connections with other types of connections.
It is possible for a host to have both iSCSI (Ethernet) and Fibre Channel (HBA) adapters for connections to a
storage array that has a mix of HICs. Several restrictions apply to such configurations.
The root boot feature is not supported for hosts with mixed connections to one storage array.
Cluster configurations are supported for hosts with mixed connections to one storage array.
When the host operating system is VMware, mixing of connection types within a partition is not supported.
SANtricity_10.77 February 2011
LSI Corporation
- 441 -
When the host operating system is Windows, mixing of connection types within a storage partition is not
supported. A single server that attaches to multiple storage partitions on a single array must not have any
overlap in LUN number assignments given to the volumes.
For other operating systems, mixed connection types from a host to a single storage array are not
supported.
Procedure – Installing Host Bus Adapters
1. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer Partner Program link.
Check its Compatibility Matrix to make sure you have an acceptable configuration.
The Compatibility Matrix provides this information:
The latest hardware compatibility information
The models of the HBAs that are supported
The firmware requirements and the software requirements for the HBAs
2. Install your HBA according to the vendor documentation.
NOTE If your operating system is Windows Server 2008 Server Core, you might have additional
installation requirements. Refer to the Microsoft Developers Network (MSDN) for more information about
Windows Server 2008 Server Core. You can access these resources from www.microsoft.com.
3. Install the latest version of the firmware for the HBA. You can find the latest version of the firmware for the
HBA at the HBA vendor website.
IMPORTANT The remaining steps are general steps to obtain the HBA host port World Wide Name
from the HBA BIOS utility. If you have installed the host context agent on all of your hosts, you do not need
to perform these steps. If you are performing these steps, the actual prompts and screens vary depending
on the vendor that provides the HBA. Also, some HBAs have software utilities that you can use to obtain the
world wide name for the port instead of using the BIOS utility.
4. Reboot or start your host.
5. While your host is booting, look for the prompt to access the HBA BIOS utility.
6. Select each HBA to view its HBA host port world wide name.
7. Record the following information for each host and for each HBA connected to the storage array:
The name of each host
The HBAs in each host
The HBA host port world wide name of each port on the HBA
The following table shows examples of the host and HBA information that you must record.

Step 5 – Connecting the Controller Tray to the Hosts
Key Terms
access volume
A special volume that is used by the host-agent software to communicate management requests and event
information between the management station and the storage array. An access volume is required only for in-
band management.
direct topology
A topology that does not use a switch.
Dynamic Host Configuration Protocol (DHCP)
CONTEXT [Network] An Internet protocol that allows nodes to dynamically acquire ('lease') network
addresses for periods of time rather than having to pre-configure them. DHCP greatly simplifies the
administration of large networks, and networks in which nodes frequently join and depart. (The Dictionary of
Storage Networking Terminology)
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
stateless address autoconfiguration
A method for setting the Internet Protocol (IP) address of an Ethernet port automatically. This method is
applicable only for IPv6 networks.
switch topology
A topology that uses a switch.
topology
The logical layout of the components of a computer system or network and their interconnections. Topology
deals with questions of what components are directly connected to other components from the standpoint
of being able to communicate. It does not deal with questions of physical location of components or
interconnecting cables. (The Dictionary of Storage Networking Terminology)
World Wide Identifier (WWID)
CONTEXT [Fibre Channel] A unique 64-bit number assigned by a recognized naming authority (often using
a block assignment to a manufacturer) that identifies a node process or node port. A WWID is assigned for
the life of a connection (device). Most networking physical transport network technologies use a world wide
unique identifier convention. For example, the Ethernet Media Access Control Identifier is often referred to as
the MAC address. (The Dictionary of Storage Networking Terminology)

Things to Know – Host Channels on the CE7900 Controller Tray
Each controller has four dual-ported host channels.
Each group of two channels is associated with one host interface card.
Controller A is inverted from controller B, which means that its host channels are upside-down and
numbered in reverse order.
Host Channels on the Controllers – Rear View
1. Host Channels
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when you handle tray components.
Things to Know – Host Interface Cards
The CE7900 controller tray supports several types of host interface cards (HICs) for different speeds an
protocol. Keep these guidelines in mind:
20-Gb/s InfiniBand
10-Gb/s iSCSI
8-Gb/s Fibre Channel
4-Gb/s Fibre Channel
1-Gb/s iSCSI
A CE7900 controller tray with InfiniBand HICs must have only InfiniBand HICs.
If you connect a 4-Gb/s Fibre Channel HIC with an 8-Gb/s HBA on a host, the data transfer rate is 4 Gb/s.
A controller might have a mix with one 4-Gb/s Fibre Channel HIC and one 8-Gb/s Fibre Channel HIC or it
might have a mix with one Fibre Channel HIC and one 1-Gb/s iSCSI HIC or one 10-Gb/s iSCSI HIC.
When HICs are mixed, each controller in a duplex system must have the exact same HIC configuration.
SANtricity_10.77 February 2011
LSI Corporation
- 448 -
When Fibre Channel HICs with different data rates are mixed and you are cabling for redundancy, cable
the HBAs on the host to the HICs with the same data rate, one on controller A and one on controller B.
Procedure – Connecting Host Cables on the CE7900 Controller Tray
Make sure that you have installed your host adapters. Refer to the documentation for your host adapters for
information about how to install the host adapter and how to use the supplied configuration utilities.
The figures in this section show Fibre Channel connections as examples and identify HBA1 and HBA2 as
connecting points on the hosts. For other configurations, these connecting points might be host channel
adapters (HCAs) for InfiniBand connections, Ethernet adapters for iSCSI connections, or a combination of
one HBA and one iSCSI Ethernet adapter.
Fibre Channel and InfiniBand connections require fiber-optic cables. Connections for iSCSI require copper
cables with RJ-45 connectors. The cabling patterns are the same for all types of cables and connectors.
IMPORTANT Small Form-factor Pluggable (SFP) transceivers are required for Fibre Channel and
InfiniBand host connections for 20-Gb/s InfiniBand, 10-Gb/s iSCSI, 8-Gb/s Fibre Channel, and 4-Gb/s Fibre
Channel connections, each requires a different type of SFP transceiver. Be sure to use SFP transceivers that
match the data rate and protocol for the connection that you are making.
This procedure is for a direct topology as shown in Figure 1–1. See Figure 1–2 and Figure 1–3 for example
cabling patterns for fabric and mixed topologies. A Fibre Channel host connections require SFP transceivers
in the HIC and in the HBA.
1. If you are cabling a Fibre Channel connection, make sure that an SFP transceiver is inserted into the host
port on the HIC and the corresponding port on the HBA in the host. Make sure that any black plastic plugs
that might be present are removed from the SFP transceivers.
2. Starting with the first host channel of each controller, perform one of these actions:
For a Fibre Channel or an InfiniBand connection, plug one end of the cable into the SFP transceiver
in a port.
For an iSCSI connection, plug the RJ-45 connector on one end of the cable directly into a port.
3. Plug the other end of the cable into one of the host adapter ports in the host.
For a Fibre Channel or an InfiniBand connection, plug one end of the cable into the SFP transceiver
in a port.
For an iSCSI connection, plug the RJ-45 connector on one end of the cable directly into a port.
Make sure that the speed and protocol used by the host adapter match those used by the HIC.
4. Affix a label to each end of the cable with the following information. A label is very important if you need to
disconnect cables to service a controller.
The host name and the host adapter port
The controller ID (for example, controller A)
The host channel ID (for example, host channel 1)
Example label abbreviation – Assume that a cable is connected between port 1 in HBA 1 of a host
named Engineering and host channel 1 of controller A.

NOTE If you are cabling for a fabric or mixed topology, include the appropriate switch name and
port number on the label.
5. Repeat step 2 through step 4 for each controller and host channel that you intend to use.
NOTE If you do not use a host channel, remove the SFP transceiver. You can use a 4-Gb/s SFP
transceiver in a drive channel port or in an ESM on the drive tray.

ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when you handle tray components.
The CE7900 controller tray supports only FC4600 drive trays and DE6900 drive trays. You cannot
connect any other type of drive tray to the controller tray.
Each controller has four drive channels, and each drive channel has two ports, so each controller has
eight drive ports.
Controller A is inverted from controller B, which means that its drive channels are upside-down and
numbered in reverse.
Drive Channel Ports on the Controller Tray – Rear View
1. Drive Channel Ports
A controller tray has eight redundant path pairs that are formed using one drive channel of controller A
and one drive channel of controller B. The following figure shows the redundant pairs in a controller tray.
The following table lists the numbers of the redundant path pairs and the drive ports of the drive channels
from which the redundant path pairs are formed.

Things to Know – Mixing Drive Tray Types
When a mix of FC4600 drive trays and DE6900 drive trays is cabled to the controller tray, the total number of
drives must not exceed 448. If FC4600 drive trays and DE6900 drive trays are mixed on the same loop, the
loop must not have more than two DE6900 drive trays or more than seven FC4600 drive trays.
Things to Know – Connecting the Drive Trays
Cable drive trays to the controller tray by using fiber-optic cables with Small Form-factor Pluggable (SFP)
transceivers for 4-Gb/s Fibre Channel connections. The figures in "Procedure – Connecting DE6900 Drive
Trays and FC4600 Drive Trays to the CE7900 Controller Tray" shows representative configurations for
standard cabling.
You can cable the CE7900 controller tray to DE6900 drive trays, FC4600 drive trays, or a combination of
the two. No more than seven FC4600 drive trays may be cabled to one loop pair and no more than 28 total
FC4600 drive trays may be cabled to the controller tray. No more than two DE6900 drive trays may be cabled
to one loop pair and no more than eight total DE6900 drive trays may be cabled to the controller tray.
If you are adding the drive tray to an existing storage array, look at the storage array profile for your storage
array. The storage array profile shows information about the number of drive trays that are supported by your
storage array. The storage array profile shows this information:
The number of drive trays that are currently attached to the storage array
The number of drive trays that you are allowed to add to the storage array
IMPORTANT Do not add more drive trays than the storage array supports. Adding more drive trays
makes the storage array invalid. You cannot perform configuration operations, but you can continue to
transfer I/O data to the existing volumes.
HotScale™ technology lets you configure, reconfigure, add, or relocate storage array capacity without
interrupting user access to data. Contact a Customer and Technical Support representative before
proceeding. Refer to the on the SANtricity ES Storage Manager Installation DVD for more information.
ATTENTION Possible loss of data access – Contact a Customer and Technical Support
representative if you plan to add a drive tray to an existing storage array under either of the following
conditions: The power is not turned off to the controller tray, or data transfer continues to the storage array.
Procedure – Connecting DE6900 Drive Trays and FC4600 Drive Trays to the
CE7900 Controller Tray
NOTE This procedure describes standard cabling for the DE6900 drive tray and the FC4600 drive
tray. Drive-side trunking for the DE6900 drive tray follows a different pattern. Refer to either the Hardware
Cabling electronic document topics or to the PDF on the SANtricity ES Storage Manager Installation DVD for
information on how to cable for drive-side trunking.
1. Insert an SFP transceiver into the drive channel port, and plug one end of the fiber-optic cable into the
drive channel port.
NOTE Before you use an SFP transceiver, if a black, plastic plug is in the port where the SFP
transceiver will be inserted, remove the plug.
SANtricity_10.77 February 2011
LSI Corporation
- 476 -
2. Insert an SFP transceiver into the applicable In (1A) port or Out (1B) port on the ESM in the drive tray,
and plug the other end of the fiber-optic cable into the applicable In (1A) port or Out (1B) port.
3. Affix a label to each end of the cable using this recommended scheme. A label is useful if you need to
disconnect cables later to service a controller.
The controller ID (for example, controller A)
The drive channel number and the port ID (for example, drive channel 1, port 4)
The ESM ID (for example, ESM A)
The ESM port ID (for example, 1A or 1B)
The drive tray ID
Example label abbreviation– Assume that a cable is connected between drive channel 1, port 4, of
controller A to the Out (1B) port of the left ESM (A) in drive tray 1. A label abbreviation could be as
follows.
CtA-Dch1/P4, Dm1-ESM_A(left), IB
4. Repeat step 1 through step 3 for each controller and drive channel that you intend to use.
NOTE You must connect the cables from one drive tray to the next (daisy-chaining), starting with
the ninth FC4600 drive tray. If only DE6900 drive trays are used, all drive trays up to the maximum of
eight are connected directly to the CE7900 controller tray for standard cabling.
Example: In the cabling configuration figures that follow, the controller tray is placed in the center, and the
controllers are labeled as A and B. The FC4600 drive trays are placed above the controller tray and below
the controller tray. The DE6900 drive trays are placed below the controller tray, beginning at the bottom of the
cabinet. The drive trays are labeled as 1, 2, 3, and so on.

Step 8 – Connecting the Ethernet Cables
Key Terms
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
Things to Know – Connecting Ethernet Cables
ATTENTION Risk of security breach – Connect the Ethernet ports on the controller tray to a private
network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array
might be at risk of being accessed from outside of your network.
These Ethernet connections are intended for out-of-band management and have nothing to do with the
iSCSI host interface cards (HICs), whether 1Gb/s or 10Gb/s.
Ethernet port 2 on each controller is reserved for access by your Customer and Technical Support
representative.
In limited situations in which the storage management station is connected directly to the controller tray,
you must use an Ethernet crossover cable. An Ethernet crossover cable is a special cable that reverses
the pin contacts between the two ends of the cable.
Procedure – Connecting Ethernet Cables
Perform these steps to connect Ethernet cables for out-of-band management. If you use only in-band
management, skip these steps.
1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.
2. Connect the other end to the applicable network connection.
3. Repeat step 1 through step 2 for controller B.

Step 9 – Connecting the Power Cords in a CE7900 Controller Tray
Configuration
The CE7900 controller tray, the DE6900 drive tray, and the FC4600 drive tray have standard power
connections to an AC power source.
IMPORTANT Make sure that you do not turn on the power to the controller tray or the connected drive
trays until this documentation instructs you to do so. For the correct procedure for turning on the power, see
“Step 10 – Turning on the Power and Checking for Problems in a CE7900 Controller Tray Configuration.”
Things to Know – AC Power Cords
For each AC power connector on the drive tray, make sure that you use a separate power source in the
cabinet. Connecting to independent power sources maintains power redundancy.
To ensure proper cooling and assure availability, the drive trays always use two power supplies.
You can use the power cords shipped with the drive tray with typical outlets used in the destination
country, such as a wall receptacle or an uninterruptible power supply (UPS). These power cords,
however, are not intended for use in most EIA-compliant cabinets.
Procedure – Connecting AC Power Cords
1. Make sure that the circuit breakers in the cabinet are turned off.
2. Make sure that both of the Power switches on the drive trays are turned off.
3. Connect the primary power cords from the cabinet to the external power source.
4. Connect a cabinet interconnect power cord (or power cords specific to your particular cabinet) to the AC
power connector on each power canister in the drive tray.
5. If you are installing other drive trays in the cabinet, connect a power cord to each power canister in the
drive trays.

Step 10 – Turning on the Power and Checking for Problems in a
CE7900 Controller Tray Configuration
Once you complete this task, you can install the begin to install the software and perform basic configuration
tasks on your storage array. Continue with the Initial Configuration and Software Installation in these
electronic document topics or through the PDF that is available on the SANtricity ES Storage Manager
Installation DVD.
Procedure – Turning on the Power to the Storage Array and Checking for
Problems
IMPORTANT You must turn on the power to all of the connected drive trays before you turn on the
power for the controller tray. Performing this action makes sure that the controllers recognize each attached
drive tray.
NOTE While the power is being applied to the trays, the LEDs on the front and the rear of the trays
come on and go off intermittently.
1. Turn on both Power switches on each drive tray that is attached to the controller tray. Depending on your
configuration, it can take several minutes for each drive tray to complete the power-on process.
IMPORTANT Before you go to step 2, check the LEDs on the drive tray to verify that the power was
successfully applied to all of the drive trays. Wait 30 seconds after turning on the power to the drive tray
before turning on the power to the controller tray.
2. Turn on both Power switches on the rear of the controller tray. Depending on your configuration, it can
take several minutes for the controller tray to complete the power-on process.
3. Check the LEDs on the front and the rear of the controller tray and the attached drive trays (see “Things
to Know – LEDs on the CE7900 Controller Tray,” "Things to Know – LEDs on the DE6900 Drive
Tray,"and “Things to Know – LEDs on the FC4600 Drive Tray”).

Things to Know – Service Action Allowed LED
Each controller canister, power-fan canister, and interconnect-battery canister has a Service Action Allowed
LED, which is a blue LED. The Service Action Allowed LED lets you know when you can remove a canister
safely.
ATTENTION Possible loss of data access – Never remove a controller canister, a power-fan
canister, or an interconnect-battery canister unless the Service Action Allowed LED is on.
If a controller canister, a power-fan canister, or a interconnect-battery canister fails and must be replaced,
the Service Action Required (Fault) LED (an amber LED) on that canister comes on to indicate that service
action is required. The Service Action Allowed LED also comes on if it is safe to remove the canister. If data
availability dependencies exist or other conditions that dictate a canister should not be removed, the Service
Action Allowed LED stays off.
The Service Action Allowed LED automatically comes on or goes off as conditions change. In most cases,
the Service Action Allowed LED comes on when the Service Action Required (Fault) LED comes on for a
canister.
IMPORTANT If the Service Action Required (Fault) LED comes on but the Service Action Allowed
LED is off for a particular canister, you might need to service another canister first. Check your storage
management software to determine the action that you should take.

Things to Know – SFP Transceivers, Fiber-Optic Cables, Copper Cables, and
SAS Cables
The figures in this topic display the fiber-optic, copper cables, and SFP transceivers.
NOTE Your SFP transceivers and cables might look slightly different from the ones shown. The
differences do not affect the performance of the SFP transceivers.
The controller-drive tray supports SAS, Fibre Channel (FC), and iSCSI host connections and SAS drive
connections. FC host connections might operate at 8 Gb/s or at a lower data rate. Ports for 8-Gb/s Fibre
Channel host connections require SFP transceivers designed for this data rate. These SFP transceivers look
similar to other SFP transceivers but are not compatible with other types of connections. SFP transceivers for
1-Gb/s iSCSI connections and 10-Gb/s iSCSI connections have a different physical interface for the cable and
are not compatible with other types of connections.
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a

Step 3 – Installing the Host Bus Adapters for the CDE4900
Controller-Drive Tray Configuration
Key Terms
HBA host port
The physical and electrical interface on the host bus adapter (HBA) that provides for the connection between
the host and the controller. Most HBAs will have either one or two host ports. The HBA has a unique World
Wide Identifier (WWID) and each HBA host port has a unique WWID.
HBA host port world wide name
A 16-character unique name that is provided for each port on the host bus adapter (HBA).
host bus adapter (HBA)
A physical board that resides in the host. The HBA provides for data transfer between the host and the
controllers in the storage array over the I/O host interface. Each HBA contains one or more physical ports.
Things to Know – Host Bus Adapters and Ethernet Network Interface Cards
The CDE2600 controller-drive tray supports dual 6-Gb/s SAS host connections and optional host interface
cards (HICs) for dual 6-Gb/s SAS, four 1-Gb/s iSCSI, two 10-Gb iSCSI, and four 8-Gb/s FC connections.
The connections on a host must match the type (SAS HBAs for SAS, FC HBAs for FC, or iSCSI HBAs or
Ethernet network interface cards [NICs] for iSCSI) of the HICs to which you connect them. For the best
performance, HBAs for SAS and FC connections should support the highest data rate supported by the
HICs to which they connect.
For maximum hardware redundancy, you must install a minimum of two HBAs (for either SAS or FC host
connections) or two NICs or iSCSI HBAs (for iSCSI host connections) in each host. Using both ports of a
dual-port HBA or a dual-port NIC provides two paths to the storage array but does not ensure redundancy
if an HBA or a NIC fails.
NOTE You can use the Compatibility Matrix to obtain information about the supported models of the
HBAs and their requirements. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer
Partner Program link. Check its Compatibility Matrix to make sure you have an acceptable configuration.
Most of the HBAs, as shipped from the vendor, require updated firmware and software drivers to work
correctly with the storage array. For information about the updates, refer to the website of the HBA
vendor.
Procedure – Installing Host Bus Adapters
1. Go to http://www.lsi.com/compatibilitymatrix/, and select the desired Developer Partner Program link.
Check its Compatibility Matrix to make sure you have an acceptable configuration.
The Compatibility Matrix provides this information:
The latest hardware compatibility information
The models of the HBAs that are supported
The firmware requirements and the software requirements for the HBAs
2. Install your HBA according to the vendor documentation.

NOTE If your operating system is Windows Server 2008 Server Core, you might have additional
installation requirements. Refer to the Microsoft Developers Network (MSDN) for more information about
Windows Server 2008 Server Core. You can access these resources from www.microsoft.com.
3. Install the latest version of the firmware for the HBA. You can find the latest version of the firmware for the
HBA at the HBA vendor website.
IMPORTANT The remaining steps are general steps to obtain the HBA host port World Wide Name
from the HBA BIOS utility. If you have installed the host context agent on all of your hosts, you do not need
to perform these steps. If you are performing these steps, the actual prompts and screens vary depending
on the vendor that provides the HBA. Also, some HBAs have software utilities that you can use to obtain the
world wide name for the port instead of using the BIOS utility.
4. Reboot or start your host.
5. While your host is booting, look for the prompt to access the HBA BIOS utility.
6. Select each HBA to view its HBA host port world wide name.
7. Record the following information for each host and for each HBA connected to the storage array:
The name of each host
The HBAs in each host
The HBA host port world wide name of each port on the HBA

If you are installing the mounting rails above an existing tray, position the mounting rails directly
above the tray.
If you are installing the mounting rails below an existing tray, allow 17.8-cm (7.00-in.) clearance below
the existing tray.
ATTENTION Risk of equipment malfunction – To avoid exceeding the functional and
environmental limits, install only drives that have been provided or approved by the original manufacturer.
Not all controller-drive trays are shipped with pre-populated drives. System integrators, resellers, system
administrators, or users of the controller-drive tray can install the drives.
NOTE Make sure that you place the controller-drive tray in the middle portion of the cabinet while
allowing room for drive trays to be placed above and below the controller-drive tray. As you add drive
trays, position them below and above the controller-drive tray, alternating so that the cabinet does not
become top heavy.
4. With the help of two other persons, slide the rear of the controller-drive tray onto the mounting rails.
Make sure that the top mounting holes on the controller-drive tray align with the mounting rail holes of the
cabinet.
The rear of the controller-drive tray slides into the slots on the mounting rails.
Securing the Controller-Drive Tray to the Cabinet
1. Screws
2. Mounting Holes
NOTE The rear of the controller-drive tray contains two controllers. The top of the controller-drive
tray is the side with the labels.
5. Secure screws in the top mounting holes and the bottom mounting holes on each side of the controller-
drive tray.

topology
The logical layout of the components of a computer system or network and their interconnections. Topology
deals with questions of what components are directly connected to other components from the standpoint
of being able to communicate. It does not deal with questions of physical location of components or
interconnecting cables. (The Dictionary of Storage Networking Terminology)
Things to Know – Host Channels
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when you handle tray components.
Each controller has two or four host ports.
Two of the host ports are standard and support 8-Gb/s, 4-Gb/s or 2 Gb/s Fibre Channel (FC) data rates.
The data rate will auto-negotiate to the highest value supported by the host.
Two of the host ports are optional, and, if present, are located on a replaceable host interface card (HIC).
Two different types of HICs are supported. One option has two FC host ports with the same specifications
as the standard host ports. The second option has two iSCSI host ports. The iSCSI host ports can be
used for 10-Gb/s connections or 1-Gb/s connections. The data rate for the iSCSI ports must be set
manually, and each data rate requires a different type of SFP transceiver.
Labeling on the face plate of the HIC identifies the type of connection: FC or iSCSI. If no HIC is installed,
a blank face plate covers the location for the HIC.
Controller A is inverted from controller B, which means that its host channels are upside-down.

Host Channels on the Controllers – Rear View
1. Standard Host Channels
2. Optional Host Channels
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.
Procedure – Connecting Host Cables
IMPORTANT Make sure that you have installed your HBAs. Refer to the documentation for your HBAs
for information about how to install the HBA and how to use the supplied configuration utilities.
The type of HICs, Fibre Channel (FC) or iSCSI, must match the type of the host bus adapters (HBAs) to
which you connect them. If you are mixing FC host connections and iSCSI host connections, each host
connection of a redundant pair must connect to the same type of host port, one on controller A and one on
controller B.
Fiber-optic connections for 8-Gb/s FC require special SFP transceivers that support the higher data rate.
Similarly, 10-Gb/s fiber-optic iSCSI connections require special SFP transceivers. 10-Gb/s iSCSI connections
require both special SFP transceivers and Ethernet cables. SFP transceivers installed in the controller, the
host, and, optionally, the switch must all support the same data rate to achieve the best performance.
If you are using iSCSI with a fabric topology, the iSCSI connections might require a different type of switch
from the FC connections.
Refer to the figures just below for example cabling patterns.
1. Make sure that the appropriate type of SFP transceiver is inserted into the host channel.
2. If a black, plastic plug is in the SFP transceiver, remove it.
SANtricity_10.77 February 2011
LSI Corporation
- 529 -
3. Starting with the first host channel of each controller, plug one end of the cable into the SFP transceiver in
the host channel.
The cable is an Ethernet cable with RJ-45 connectors for 1-Gb/s iSCSI connections, or a fiber-optic cable
for all other types of connections.
4. Plug the other end of the cable into an HBA in the host (direct topology) or into a switch (fabric topology).
5. Affix a label to each end of the cable with this information. A label is very important if you need to
disconnect cables to service a controller. Include this information on the labels:
The host name and the HBA port (for direct topology)
The switch name and the port (for fabric topology)
The controller ID (for example, controller A)
The host channel ID (for example, host channel 1)
Example label abbreviation – Assume that a cable is connected between port 1 in HBA 1 of a host
named Engineering and host channel 1 of controller A. A label abbreviation could be as follows.
6. Repeat step 1 through step 5 for each controller and host channel that you intend to use.
NOTE If you do not use a Fibre Channel host port, remove the SFP transceiver. You might be able
to use this SFP transceiver in a drive channel port or in an ESM on a drive tray.

Step 6 – Installing the Drive Trays for the CDE4900 Controller-
Drive Tray Configurations
Things to Know – General Installation
IMPORTANT If you are installing the drive tray in a cabinet with other trays, make sure that the
combined power requirements of the drive tray and the other trays do not exceed the power capacity of your
cabinet.
Special site preparation is not required for this drive tray beyond what is normally found in a computer lab
environment.
The power supplies meet standard voltage requirements for both domestic and worldwide operation.
If you are installing drive trays and the controller-drive tray at the same time, take these precautions:
Install the controller-drive tray in a location within the cabinet that lets you evenly distribute the drive
trays around the controller-drive tray.
Keep as much weight as possible in the bottom half of the cabinet.
IMPORTANT After you install the drive tray, you might replace drives or install additional drives. If you
replace or add more than one drive without powering down the drive tray, install the drives one at a time. Wait
10 seconds after you insert each drive before inserting the next one.
For Additional Information on Drive Tray Installation
Refer to the Storage System Site Preparation Guide on the SANtricity ES Storage Manager Installation DVD

NOTE While the power is being applied to the trays, the LEDs on the front and the rear of the trays
come on and go off intermittently.
1. Turn on both Power switches on each drive tray that is attached to the controller-drive tray. Depending on
your configuration, it can take several minutes for each drive tray to complete the power-on process.
IMPORTANT Before you go to step 2, check the LEDs on the drive trays to verify that the power
was successfully applied to all of the drive trays. Wait 30 seconds after turning on the power to the drive
trays before turning on the power to the controller-drive tray.
2. Turn on both Power switches on the rear of the controller-drive tray. Depending on your configuration, it
can take several minutes for the controller-drive tray to complete the power-on process.
3. Check the LEDs on the front and the rear of the controller-drive tray and the attached drive trays.
4. If you see any amber LEDs, make a note of their location.

Cabling Concepts and Best Practices
This chapter has three sections:
The first section, “Cabling Concepts,” provides definitions of the terms used in this document. This section
is intended primarily for reference. Read the entire section to increase your overall understanding of the
storage array and help you to optimize your storage array.
The second section, “Best Practices,” contains information that might affect your choice of cabling
topologies. Read this section to understand the options for cabling your storage array.
The third section, “Common Procedures,” contains procedures that you will need to perform while you
are cabling the storage array. Read this section to understand tasks that might be required to cable your
storage array.
Cabling Concepts
This section defines terms and concepts that are used in this document.
Fabric (Switched) Topologies Compared to Direct-Attach Topologies
Fabric topologies use a switch. Direct-attach topologies do not use a switch. A switched topology is required if
the number of hosts to connect to a controller tray or controller-drive tray is greater than the number available
host ports on the tray.
Host connections might be InfiniBand, Fibre Channel, iSCSI, or a mix of Fibre Channel and iSCSI. Switches
must support the required connection type or types. A combination of switches of different types might be
appropriate for some configurations that support a mixture of connection types.
Drive Tray
A drive tray contains drives but no controllers. Drive trays usually are attached to either a controller tray or
a controller-drive tray so that the controller in the controller tray or the controller-drive tray can configure,
access, and manage the storage space in the drive tray. Drive trays can be differentiated by type, which are
described in the following subsections.
Switched Bunch of Disks
Switched Bunch of Disks (SBOD) is a device that takes all of the drives that are operating in a single Fibre
Channel-Arbitrated Loop (FC-AL) segment and provides each drive with access to one or more controllers in
a point-to-point fashion. This action is accomplished in a way that appears to be compliant with the FC-AL-2
protocol. As a result, system firmware changes are not required.
In this document, the FC2610 drive trays and the FC4600 drive trays are referred to as SBODs in the cabling
diagrams. The AT2655 drive trays are identified as SATA (Serial Advanced Technology). The following figure
shows an example of this type of labeling for drive trays. The DE6900 drive trays and DE6600 drive trays are
SBODs and can be mixed only with FC4600 drive trays. Do not mix FC2600 drive trays with other types of
drive trays on the same loop.
SANtricity_10.77 February 2011

SBOD Labeling in Cabling Diagrams
Controller Tray
A controller tray contains controllers. A controller tray does not contain drives. Controller trays configure,
access, and manage the storage space of attached drive trays.
Controller-Drive Tray
A controller-drive tray contains both controllers and drives. The controllers configure, access, and manage
the storage space of the drives in the controller-drive tray. A controller-drive tray might configure, access, and
manage the storage space of other attached drive trays, depending upon the model.
Host Channels and Drive Channels
In this document, the term channel refers to a path for the transfer of data information and control information
between the host and the controller, or between the drive trays and the controller trays or controller-drive
trays. A data path from a host to a controller is a host channel. A host channel might be Fibre Channel,
InfiniBand, iSCSI, or Serial Attached SCSI (SAS). A path from a drive trays to a controller trays or a controller-
drive trays is a drive channel. Each drive channel is defined by a single Fibre Channel-Arbitrated Loop or by a
series of SAS devices connected through expanders. Controllers have between two and eight available host
channels, and between one and eight available drive channels, depending upon the model. The maximum
number of hosts per host channel and the maximum number of drives per drive channel depends upon the
model. For model-specific information, see the topics under "Product Compatibility."
SANtricity_10.77 February 2011
LSI Corporation
- 560 -
IMPORTANT When you mix different types of drive trays, you must consider the total number of drives
that are available in the final configuration of the storage array. For example, if you mix FC4600 drive trays
with FC2610 drive trays, the total number of drives might be more than the maximum number that each drive
channel can support.
Host Ports and Drive Ports
The ports are the physical connectors on the controller tray or the controller-drive tray that, along with the
cabling, enable the transfer of data. If the port communicates with the host server, it is a host port. If the port
communicates with a drive tray, it is a drive port. The figures in the topics under "Component Locations" show
the connectors on the rear of each of the various trays. These figures will help you differentiate between host
ports and drive ports.
Dual-Ported Drives
Each drive in a controller-drive tray or a drive tray is dual ported. Circuitry in the drive tray or the controller-
drive tray connects one drive port to one channel and the other port to another channel. Therefore, if one
drive port or drive channel fails, the data on the drive is accessible through the other drive port or drive
channel.
SATA drives are not dual ported; however, the electronics in the AT2655 drive tray emulate the behavior of
dual-ported drives. Each SATA drive is available through two paths.
Preferred Controllers and Alternate Controllers
The preferred controller is the controller that “owns” a volume or a volume group. SANtricity ES Storage
Manager automatically selects the preferred controller when a volume is created, or the user can override the
default selection.
Several conditions will force the preferred controller to fail over to the alternate controller. When this event
occurs, ownership of the volume is shifted to the alternate controller. These conditions might initiate failover:
The preferred controller is physically removed.
The preferred controller is being updated with new firmware.
The preferred controller has sustained a fatal event.
The paths used by the preferred controller to access either the drives or the host are called the preferred
paths, and the redundant paths are the alternate paths. If a failure occurs that causes the preferred path
to become inaccessible, the alternate path software detects the failure and automatically switches to the
alternate path.
Alternate Path Software
Alternate path software or an alternate path (failover) driver is a software tool that provides redundant data
path management between the host bus adapter (HBA) and the controller. This tool is installed on the host in
a system that provides redundant HBAs and paths. The tool discovers and identifies multiple paths to a single
logical unit number (LUN) and establishes a preferred path to that LUN. If any component in the preferred
path fails, the alternate path software automatically reroutes input/output (I/O) requests to the alternate path
so that the system continues to operate without interruption.
To learn how alternate path software works with SANtricity ES Storage Manager features to provide data
path protection, refer to the topics under Conecpts or the corresponding PDF document on the SANtricity ES
Storage Manager Installation DVD.
SANtricity_10.77 February 2011
LSI Corporation
- 561 -
Failover
Failover is an automatic operation that switches from a failed component or failing component to an
operational component. In the case of a Redundant Array of Independent Disks (RAID) controller failover, an
operational controller takes over the ownership of volumes. The operational controller processes I/O from the
host in place of the failing component or failed controller. Controller failover is possible only in controller trays
or in controller-drive trays that contain two controllers.
In a system in which the alternate path software tool is installed on the host, the data paths through the failed
HBA are replaced by data paths through the surviving HBA.
For more information, refer to the topics under Failover or to the corresponding PDF on the SANtricity ES
Storage Manager Installation DVD.
Redundant and Non-Redundant
The term redundant means “more than one” and indicates the existence of something more than what is
essential to accomplish a task. In RAID technology, redundancy means that duplicated components or data
exist, or an alternate means can provide essential services. This redundancy ensures the availability of data
in case a component fails.
In most RAID systems, most of the components are redundant, but that the system might not be fully
redundant. In other words, there might be one or two components whose individual failures would cause loss
of access to data. Therefore, a fully redundant system duplicates all components and is configured to make
sure that the duplicate components can be accessed in case of a failure. The manner in which the system is
cabled is an essential component of creating a successfully configured redundant system.
Single Point of Failure
Any component or path that is not duplicated (redundant) or whose failure can cause loss of data access is
called a potential single point of failure. The cabling scenarios in this document note the components that
present a potential single point of failure. Choose a cabling topology that does not create a single point of
failure.
SFP Transceivers, Fiber-Optic Cables, and Copper Cables
Controller-drive trays, controller trays, and drive trays use fiber-optic cables or copper cables for Fibre
Channel connections. For copper Fibre Channel cables, a passive copper Small Form-factor Pluggable (SFP)
transceiver is attached to each end of the cable. InfiniBand connections are made with fiber-optic cables. If
your system will be connected with Fibre Channel or InfiniBand fiber-optic cables, you must install an active
SFP transceiver into each port in which a fiber-optic cable will be connected before plugging in the fiber-optic
cable. Connections for 1-Gb/s iSCSI require SFP transceivers. Connections for 1-Gb/s iSCSI use copper
cables with RJ-45 connectors and do not require SFP transceivers. Connections for SAS use copper cables
with SFF 8088 connectors and do not require SFP transceivers. The following figures show the two types of
cables that use SFP transceivers. Note that your SFP transceivers and cables might look slightly different
from the ones shown. The differences do not affect the performance of the SFP transceivers.
WARNING (W03) Risk of exposure to laser radiation – Do not disassemble or remove any part of a
Small Form-factor Pluggable (SFP) transceiver because you might be exposed to laser radiation.

Host Adapters
Each connection from a host port on a controller tray or a controller-drive tray to a host is made through
a host adapter on the host. A host adapter can be a host bus adapter (HBA) for Fibre Channel or SAS
connections, a host channel adapter (HCA) for InfiniBand connections, or an Ethernet adapter for iSCSI
connections. The host adapter provides the interface to the internal bus of the host. For hardware
redundancy, use two host adapters in each host computer. The two host adapters must be of the same type
(HBAs, HCAs, or Ethernet). For duplex controller trays or duplex controller-drive trays, connect each host
adapter to a different controller in a controller tray or a controller-drive tray to make sure that the server will be
accessible even if one HBA or one controller fails.
ATTENTION Possible loss of data access – Do not use a combination of HBAs from different
vendors in the same storage area network (SAN). For the HBAs to perform correctly, use HBAs from only one
manufacturer in a SAN.
You can obtain information about supported host adapters from the Compatibility Matrix. To check for
current compatibility, refer to the Compatibility Matrix at http://www.lsi.com/compatibilitymatrix/, and click the
Compatibility Matrix link.
Host Interface Cards
Each controller in a CE7900 controller tray has one or two host interface cards (HICs) that contain the host
ports. Each controller in a CDE4900 controller-drive tray has two Fibre Channel host ports built in, as well as
an optional HIC for additional host ports. Each controller in a CDE2600 controller-drive tray or a CDE2600-60
controller-drive tray has two SAS host ports built in, as well as an optional HIC for additional host ports.
SANtricity_10.77 February 2011
LSI Corporation
- 563 -
An HIC is cabled to a host adapter: a host bus adapter (HBA) for Fibre Channel or SAS, a host channel
adapter (HCA) for InfiniBand, or an Ethernet adapter for iSCSI. The host adapter in the host must match the
type of HIC to which it is cabled.
Network Interface Cards
A network interface card (NIC) is an expansion board that is installed in the host server. Some servers are
equipped with an integrated NIC. The NIC supports Ethernet technology. The NIC is required for network
communication. Each Ethernet cable connection for out-of-band storage array management is made through
an NIC (see the topics under "In-Band Management and Out-of-Band Management").
NOTE It is the responsibility of the customer to obtain the required NICs and to install them.
Switches and Zoning
A switch is an intelligent device that connects multiple devices. A switch allows data transfer between
the devices, depending upon the designated source (initiator) and the destination (target) of the data.
Switches can redirect traffic to ports other than the designated destination, if necessary. A switch provides full
bandwidth per port and high-speed routing of data.
Zoning allows a single hardware switch to function as two or more virtual switches. In a zoned configuration,
communication among devices in each zone is independent of communication among devices in another
zone or zones. Zoned switches allow an administrator to restrict access to specific areas within a storage
area network (SAN).
How Initiators and Targets Respond to Zoning
When an initiator first accesses the fabric, it queries the World Wide Identifier (WWID) name server for all
of the attached disks and drive trays and their capabilities. Zoning is like a filter that the WWID name server
applies to the query from the initiator that limits the information returned by the WWID name server to the
initiator. A zone defines the WWID of the initiator and the WWID of the devices that a particular zone is
allowed to access. Devices that are not part of the zone are not returned as accessible devices.
The fabric provides universal access for all initiators and targets. Any initiator can query (probe) the fabric
for all targets, which can affect performance when many targets are connected to the fabric. The querying
process also provides access to devices for which access is not needed. Use zoning to limit the number of
devices that an initiator can access. Within your storage area network, you should zone the fabric switches so
that the initiators do not “see” or communicate with each other.
How Best to Approach Zone Configuration
Some of the cabling topologies shown in this document require the use of a zoned switch. By default, the
switch uses no zoning, which is not sufficiently robust for most applications. You must configure the switch
before you use it.
Zone configuration is managed on a per-fabric basis. While you can administer zone configuration from
any switch, use the best practice of selecting one switch for all zone administration. Give preference to the
primary switches within the SAN, and choose only a switch that has the most up-to-date storage management
software and switch management software installed on it.

In-Band Management and Out-of-Band Management
A system administrator manages a storage array from a storage management station, which is a workstation
on which the SANtricity ES Storage Manager Client is installed. Requests and status information sent
between the storage array and the storage management station are managed in one of two ways: in-band or
out-of-band. A storage array that uses out-of-band management requires a different network topology from a
storage array that uses in-band management.
When you use in-band management, a SANtricity ES Storage Manager agent running on the host receives
requests from the management station. The host agent processes the requests through the host I/O interface
to the storage array. The host I/O interface might be Fibre Channel, serial-attached Small Computer System
Interface (SAS), InfiniBand, or Internet SCSI (iSCSI).

2. User Workstations Sending and Receiving Data
3. Storage Management Station
4. Host
5. Host Adapters
6. Controller A
7. Controller B
8. Controller Tray or Controller-Drive Tray for the Storage Array
When you use out-of-band management, the storage management station is connected, through an Ethernet
network, to each of the controllers in the controller tray or the controller-drive tray.

9. Ethernet Cable from the Controllers to the Ethernet Network
When using out-of-band management, a Dynamic Host Configuration Protocol (DHCP) server is
recommended for assigning Internet Protocol (IP) addresses and other network configuration settings.
A DHCP server provides the network administrators the ability to manage and automatically assign IP
addresses. If a DHCP server is not used, you must manually configure the controllers. For more information,
refer to the Adding a Host or Storage Array online help topic in the Enterprise Management Window.
ATTENTION Risk of unauthorized access to or loss of data – If the out-of-band management
method is used, connect the Ethernet ports on the controller tray or the controller-drive tray to a private
network segment behind a firewall. If the Ethernet connection is not protected by a firewall, your storage array
might be at risk of being accessed from outside of your network.
IMPORTANT Where two Ethernet ports are available on each controller (four total), you can use one of
the ports on each controller for out-of-band Ethernet connections. Reserve the second Ethernet port on each
controller for access by your Customer and Technical Support representative.
For information about how to create a redundant out-of-band topology, see the topics under “Drive Cabling.”
Best Practices
This section explains recommended cabling practices. To make sure that your cabling topology results in
optimal performance and reliability, familiarize yourself with these best practices.

IMPORTANT If your existing storage array cabling does not comply with the best practices described in
this section, do not re-cable your storage array unless specifically requested to do so by your Customer and
Technical Support representative.
Drive Cabling for Redundancy
When attaching the drive trays, use a cabling topology that does not create a single point of failure. A single
point of failure might appear as a drive tray failure or another component failure in the middle of a grouping
of drive trays. If a drive tray fails, you can no longer access the drive trays beyond the point of failure. By
creating an alternate path, you make sure that the drive trays are accessible in the event of a drive tray
failure.
The following figure shows a typical cabling scenario. In this example, each of the eight drive trays has two
connections directly to the controller tray: one from ESM A to controller A and one from ESM B to controller B.
Each redundant path pair on the controller tray connects to one drive tray. The ESM 1B ports are used for all
of the connections.
Cabling for Eight Drive Trays
Note how the controller tray (denoted by A and B in the figure) is conveniently situated in the middle of the
arrangement, which enables you to use cables that are all the same length. Positioning the controller tray
near the middle of the cabinet also helps prevent the cabinet from becoming top heavy as drive trays are
added.
For cabling examples, ranging from simple to complex, see the topics under “Drive Cabling.”
SANtricity_10.77 February 2011

Host Cabling for Redundancy
To ensure that, in the event of a host channel failure, the storage array will stay accessible to the host,
establish two physical paths from each host to the controllers, and install alternate path software on the host.
This cabling topology, when used with alternate path software, makes sure that a redundant path exists from
the host to the controllers.
ATTENTION Possible loss of data access – You must install alternate path software or an alternate
path (failover) driver on the host to support failover in the event of an HBA failure or a host channel failure.
For examples of redundant topologies, see the topics under “Host Cabling.”
Host Cabling for Remote Volume Mirroring
The Remote Volume Mirroring premium feature provides online, real-time replication of data between storage
arrays over a remote distance. In the event of a disaster or a catastrophic failure at one storage array, you
can promote a second storage array to take over responsibility for computing services. See the topics under
“Hardware Installation for Remote Volume Mirroring” for detailed information about cabling for Remote
Volume Mirroring.
The Remote Volume Mirroring premium feature requires a dedicated host port for mirroring data between
storage arrays. After the Remote Volume Mirroring premium feature has been activated, one host I/O port on
each controller is solely dedicated to mirroring operations.
NOTE One of the host ports on each controller must be dedicated for the communication that occurs
between the two storage arrays (primary volumes and secondary volumes). If you are not using the Remote
Volume Mirroring premium feature, these host ports are available for ordinary host connections.
Cabling for Performance
Generally speaking, performance is enhanced by maximizing bandwidth, which is the ability to process more
I/O across more channels. Therefore, a configuration that maximizes the number of host channels and the
number of drive channels available to process I/O will maximize performance. Of course, faster processing
speeds also maximize performance.
The DE6900 drive tray supports drive-side trunking. You can use drive-side trunking with the appropriate
cabling configuration to, potentially, double the bandwidth available by making two drive channels
simultaneously available to the same drive tray or loop.
In addition to planning a topology that provides maximum performance, choose a RAID level that suits
the planned applications. For information on RAID levels, refer to the topics under Concepts or to the
corresponding PDF document on the SANtricity ES Storage Manager Installation DVD.
Fibre Channel Drive-Side Trunking
Drive trays that support drive-side trunking can be cabled to a controller tray through a cabling pattern that
doubles the bandwidth available to the drive trays. Trunking is possible only with drive trays that have Fibre
Channel switch on a chip (SOC) loop-switch technology.
Drive-side trunking is an important feature for high-density drive trays because it enables a configuration
with fewer drive trays connected to a controller tray to take advantage of the maximum bandwidth available
for drive connections. For example, a storage array consisting of four DE6900 drive trays connected using
SANtricity_10.77 February 2011
LSI Corporation
- 568 -
drive-side trunking to a CE7900 controller tray with two controllers can take advantage of all of the available
bandwidth on the controller tray. Without drive-side trunking, the four drive trays can only use half of the
available bandwidth.
Each environmental services monitor (ESM) on a drive tray that is capable of drive-side trunking has four
ports. In the previous example, two ports on each ESM would connect to each of two ports of a dual-ported
drive channel on the controller tray. A new drive tray could be added to the example configuration by cabling
two ports on each ESM of the new drive tray to the two available ports on each ESM of one of the existing
drive trays. The new drive tray would then share Fibre Channel loops with the drive tray to which it is cabled.
Considerations for Drive Channel Speed
When you connect multiple drive trays to the same drive channel, all of the drive trays must operate at the
same speed. If you plan to combine drive trays that operate at different speeds on the same drive channel,
you must set all of the drive trays to operate at the lowest common speed. The following table lists the
operating speeds of each supported drive tray.
Specifications for the Drive Trays

FC4600 drive tray 4 Gb/s 16 7
FC2610 drive tray 2 Gb/s 14 8

DE6900 drive tray 4 Gb/s 60 2
DE5600 drive tray 6 Gb/s 24 7
DE1600 drive tray 6 Gb/s 12 15
Multiple Types of Drive Trays
IMPORTANT Before you create a topology that combines multiple models of drive trays, make sure
that your controller tray or controller-drive tray supports this feature. You must configure the controller tray or
controller-drive tray to support multiple models of drive trays.
You can combine multiple drive tray models in a single storage array topology. Keep the following rules and
guidelines in mind when you plan to cable your storage array with more than one drive tray type:
To achieve maximum throughput performance, distribute drive trays across redundant drive channels in a
controller tray or a controller-drive tray.
Configure FC2610 drive trays and FC4600 drive trays (SBODs) in series as described in “Cabling for
Drive Trays That Support Loop Switch Technology.”
Do not create multiple series of FC2610 drive trays and FC4600 drive trays (SBODs) that are separated
by AT2655 SATA drive trays.
Whenever possible, and with consideration of the previously stated rules and guidelines, place all like
drive trays on the same drive channel.
SANtricity_10.77 February 2011

When you cable drive trays to a CE7900 controller tray, do not mix multiple types of drive trays on the
same loop.
Do not exceed the maximum number of drives that each drive channel can support. Mixing drive trays
that contain 16 drives with drive trays that contain 14 drives can exceed the maximum number of drives
that are supported on a drive channel. Similarly, mixing drive trays that contain 24 drives with drive trays
that contain 12 drives can exceed the maximum number of drives that are supported on a drive channel.
When you cable drive trays to a controller-drive tray, keep in mind that the drives installed in the
controller-drive tray count toward the maximum number of drives supported on a drive channel.
The following table summarizes the supported combinations of controller trays or controller-drive trays with
drive trays.

Single-Controller Topologies and Dual-Controller Topologies
If you are creating a topology for a controller tray or a controller-drive tray that contains only one controller,
you can attach only drive trays that contain a single environmental services monitor (ESM). Do not attach a
drive tray that contains two ESMs to a single-controller controller tray or a single-controller controller-drive
tray.
Copper Cables and Fiber-Optic Cables
You can use a combination of copper cables and fiber-optic cables to connect the drive trays to a controller
tray or to a controller-drive tray. However, when a drive tray communicates with the controller tray (or the
controller-drive tray) indirectly, through another drive tray, the connections between the drive tray and the
controller tray (or the controller-drive tray) and between the two drive trays must use the same type of cable.
Fiber-optic cables are required for host connections.
Cabling for Drive Trays That Support Loop Switch Technology
The FC2610 drive trays and the FC4600 drive trays operate internally as an array of drives that are
connected in a point-to-point configuration by an FC-AL loop switch. These drive trays are referred to as
a Switched Bunch of Disks (SBOD). Drive trays without loop switch support operating as a string of drives
on an arbitrated loop. SBOD drive trays operate more reliably than drive trays that use a traditional loop
configuration. The loop switch also reduces transfer latency, which can increase performance in some
configurations. To operate in Switch mode, you must cluster SBOD drive trays together when they are
combined with other types of drive trays in a storage array topology.
The SBOD drive trays operate in Switch mode either when an SBOD drive tray is connected singly to a
controller tray or a controller-drive tray, or when multiple SBOD drive trays are connected in series to a
controller tray or a controller-drive tray. An SBOD drive tray operates in Hub mode when a single SBOD drive
tray is connected in series with other drive trays that do not support a loop switch. The SBOD drive trays also
operate in Hub mode when multiple SBOD drive trays are interspersed in series with other drive trays that
do not support a loop switch. The SBOD drive tray does not take advantage of the internal switch technology
when operating in Hub mode. Some statistics that are available in switch mode are not available in Hub
mode.
If SBOD drive trays are not clustered together correctly, the SANtricity ES Storage Manager software shows
a Needs Attention status for the SBOD drive trays. A Needs Attention status does not prevent the SBOD
drive trays from processing data; however, the Needs Attention status persists until you change the cabling
topology. To maximize the performance of SBOD drive trays, always cable the SBOD drive trays in a series.
SANtricity_10.77 February 2011
LSI Corporation
- 571 -
The following figure shows a simple block diagram of three recommended topologies for SBOD drive trays.
All three scenarios shown in the figure are arranged to maximize performance. The scenario on the left of the
figure (all SBODs) also offers the advantage of flexible drive cabling; for example, connecting two In ports or
two Out ports. This flexible approach to drive cabling is enabled by the Fibre Channel-Arbitrated Loop feature.
In the figure, the FC2610 drive trays or the FC4600 drive trays are identified as SBODs. The AT2655 drive
trays are identified as SATA (Serial Advanced Technology Attachment).
IMPORTANT When you connect drive trays to the CE7922 controller tray or the CE7900 controller tray,
you must not mix different types of drive trays on the same loop.
IMPORTANT When you mix different types of drive trays, you must consider the total number of drives
that are available in the final configuration of the storage array. For example, if you mix FC4600 drive trays
with FC2610 drive trays, the total number of drives might be more than the maximum number that each drive
channel can support.
Suitable Cabling Topologies for Multiple SBOD Drive Trays
Labeling Cables
Cabling is an important part of creating a robust storage array. Labeling the cables identifies system
components, drive channels, and loops. System maintenance is easier when the cables are correctly
identified. Label both ends of each cable. You can use adhesive office labels that are folded in half over
the ends of each cable. Mark the labels with the port identifiers to which the cable is connected. If you use
the recommended topologies in as described in the topics under “Host Cabling” and “Drive Cabling,” label
SANtricity_10.77 February 2011
LSI Corporation
- 572 -
each cable with the channel number noted in the table that you are following. You can provide additional
information by using color-coded cable straps (or ties) to group all of the cables associated with one
component, drive channel, or loop.
If a component fails, you must disconnect the cables, replace the failed component, and reattach the cables.
Detailed labeling of the cables will simplify the component replacement process.
If you add a new drive tray to an existing configuration, correctly labeled cables will help you identify where to
connect the new drive tray.
Cabling Information Provided by SANtricity ES Storage Manager
After you have completed your cabling topology and installed the SANtricity ES Storage Manager software,
you can view cabling information through the SANtricity ES Storage Manager software. The SANtricity ES
Storage Manager software shows a table that lists all of the connections in the cabling topology and identifies
any incorrectly cabled drive channels or non-redundant drive channels. For more information, refer to the
online help topics in the SANtricity ES Storage Manager software.
Adding New Drive Trays to an Existing Storage Array
HotScale™ technology enables you to add drive trays to an existing storage array without interrupting power
or data transfer to the storage array. See the topics under “Drive Cabling” for the recommended cabling
patterns for various numbers of attached drive trays.
When the number of drive trays exceeds the number or drive ports on a controller, the cabling pattern
changes significantly. At this point, you will start to use the “A” ports on the ESMs, and additional drive trays
connect to the controller tray indirectly, through other drive trays.
If you are adding additional drive trays to an existing configuration so that the total number of attached drive
trays will increase from fewer than the number of drive ports per controller to a total that is greater than that
number, you will need to re-cable some of the drive trays that were previously installed.
Common Procedures
This section provides procedures that are common to most cable installations.
Handling Static-Sensitive Components
Static electricity can damage dual inline memory modules (DIMMs), system boards, and other static-sensitive
components. To prevent damaging the system, follow these precautions:
Move and store all components in the static-protective packaging in which they came.
Place components on a grounded surface before removing them from their static-protective packaging.
Grounded surfaces include static-dissipating mats or grounded workstations.
Always be properly grounded when touching a static-sensitive component. To properly ground yourself,
wear a wrist strap or boot strap made for this purpose.
Handle the component by its edges. Do not touch solder joints, pins, or printed circuitry.
Use conductive field service tools.
Installing an SFP Transceiver and a Fiber-Optic Cable
You must install SFP transceivers into each connector to which you will connect a fiber-optic cable.
SANtricity_10.77 February 2011
LSI Corporation
- 573 -
ATTENTION Possible loss of data access – Fiber-optic cables are fragile. Bending, twisting, folding,
or pinching fiber-optic cables can cause damage to the cables, degraded performance, or possible loss of
data access. To prevent damage, do not twist, fold, pinch, or step on the cables. Do not bend the cables in
less than a 5-cm (2-in.) radius.
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when handling tray components.
1. Put on antistatic protection.
2. Make sure that your cables are fiber-optic cables by comparing them to the fiber-optic cable shown in the
following figure. Your SFP transceivers might look slightly different from the one shown. The differences
do not affect the performance of the SFP transceiver.

Host Cabling
This chapter provides examples of possible cabling topologies between one or more hosts and a controller
tray or a controller-drive tray. Direct-attach topologies, fabric topologies, and mixed topologies are addressed.
You are not limited to using only these topologies. Examples are provided to show basic concepts to help
you define an optimal host-cabling topology. A table that lists the maximum supported number of hosts is
included.
For host port locations on the specific controller tray model or controller-drive tray model that you are
installing, see the topics under “Component Locations.”
IMPORTANT If you are using the Remote Volume Mirroring premium feature, see the topics under
“Hardware Installation for Remote Volume Mirroring” for information on cabling using a host port between two
storage arrays.
Host Interface Connections
The CE7900 controller tray connects to hosts through one or two host interface cards (HICs). The CDE4900
controller-drive tray has built-in (base) Fibre Channel (FC) connectors for host connections and might also
have an optional HIC. The CDE2600 controller-drive tray and the CDE2600-60 controller-drive tray have
built-in (base) SAS connectors for host connections and might also have an optional HIC. All other supported
controller trays and controller-drive trays connect through built-in ports.

A CE7900 controller tray, a CDE4900 controller-drive tray, a CDE2600 controller-drive tray or a CDE2600-60
controller-drive tray can mix host interfaces of different types, with some restrictions. In all cases, when host
interface types are mixed, both controllers in a duplex controller tray or a duplex controller-drive tray must
have the same arrangement of HICs. Each controller must have the same type of HIC in the same relative
position as the other controller.
NOTE On the CDE2600 controller-drive tray, each controller has a pair of levers with handles for
removing the controller from the controller-drive tray. If a controller has a HIC installed, one of these handles
on the controller is located next to a host port on the HIC. The close spacing between the handle and the host
port might make it difficult to remove a cable that is attached to the host port. If this problem occurs, use a flat-
blade screwdriver to compress the release on the cable connector.
A HIC is connected to a host adapter: a host bus adapter (HBA) for Fibre Channel or SAS, or an Ethernet
adapter for iSCSI. The host adapter in the host must match the type of HIC to which it is connected.
For best performance, connect an 8-Gb/s Fibre Channel HIC to an 8-Gb/s HBA. If the data rate for the HBA
is lower, the data transfer rate will be at the lower rate. For instance, if you connect an 8-Gb/s Fibre Channel
HIC to a 4-Gb/s HBA, the data transfer rate is 4 Gb/s.
It is possible for a host to have both iSCSI and Fibre Channel adapters for connections to a storage array that
has a mix of HICs. Several restrictions apply to such configurations:
The root boot feature is not supported for hosts with mixed connections to one storage array.
Cluster configurations are supported for hosts with mixed connections to one storage array.
When the host operating system is VMware, mixing connection types within a storage partition is not
supported.
When the host operating system is Windows, mixing connection types within a storage partition is not
supported. A single server that attaches to multiple storage partitions on a single storage array must not
have any overlap in LUN number assignments given to the volumes.
For other operating systems, mixed connection types from a host to a single storage array are not
supported.

ATTENTION Possible loss of data access – Do not use a combination of HBAs from different
vendors in the same storage area network. For the HBAs to perform correctly, use only HBAs from one
manufacturer in a SAN.
Direct-Attach Topologies
The host-to-controller tray topologies presented in this section do not use switches. The host adapters might
be HBAs for Fibre Channel or SAS, HCAs for InfiniBand, or Ethernet for iSCSI. Some controller trays and
controller-drive trays support more direct host connections than the examples shown. To cable more host
connections, follow the pattern established by the examples in this section.
When a host is cabled to a dual-controller controller-drive tray or a dual-controller controller tray, each
attached host should have two host adapters installed. For redundancy, connect one host adapter to
controller A and the other to controller B.
One Host to a Controller Tray or a Controller-Drive Tray
The following table lists the components in this topology that are non-redundant and present a risk of a single
point of failure. The following figure shows an example of a direct-attach topology with one host and a dual-
controller controller tray or a dual-controller controller-drive tray.
The example in the figure identifies HBA1 and HBA2 as connecting points on the host. For other
configurations, these connecting points might be host channel adapters (HCAs) for InfiniBand connections,
Ethernet adapters for iSCSI connections, or a combination of one HBA and one iSCSI Ethernet adapter.
ATTENTION Possible loss of data access – You must install alternate path software or an alternate
path (failover) driver on the host to support failover in the event of an HBA, an HCA, or an iSCSI Ethernet
adapter failure or a host channel failure.

Switch Topologies
The host-to-controller tray topologies or host-to-controller-drive tray topologies presented in this section
include one or more switches. The host adapters in the hosts might be HBAs for Fibre Channel, HCAs for
InfiniBand, or Ethernet for iSCSI. Switches are not supported for SAS host connections.
When a host is cabled to a dual-controller controller-drive tray or a dual-controller controller tray, each
attached host should have two host adapters installed. For redundancy, attach each of the host adapters
to a different switch (or switch zone) so that one switch (or zone) connects to controller A and the other to
controller B in the controller tray or the controller-drive tray. In the case where a host has one HBA and one
iSCSI Ethernet adapter, the two connections might require two different types of switches.

Switch Topology – Four Hosts and a Controller Tray or a Controller-Drive Tray with Two Zoned
Switches
Mixed Topologies
The following table describes which of the components in this topology are non-redundant and present a risk
of a single point of failure. The following figure shows an example of a mixed topology; that is, a topology that
combines both switch topology and direct-attach topology. This example shows three hosts, a controller tray,
and two switches.
The example in the figure identifies HBA1 and HBA2 on each host as connecting points. For other
configurations, these connecting points might be host channel adapters (HCAs) for InfiniBand connections,
Ethernet adapters for iSCSI connections, or a combination of one HBA and one iSCSI Ethernet adapter.
Switches are not supported for SAS host connections.
When a host is cabled to a dual-controller controller-drive tray or a dual-controller controller tray, each
attached host should have two host adapters installed. The host adapters might be HBAs for Fibre Channel
or SAS, HCAs for InfiniBand, or Ethernet for iSCSI. For redundancy, attach each of the host adapters that
connects through a switch to a different switch (or switch zone) so that one switch (or zone) connects to
controller A and the other to controller B in the controller tray or the controller-drive tray. In the case where a
host has one HBA and one iSCSI Ethernet adapter, the two connections might require two different types of
switches. Redundancy for a host that attaches directly to a controller tray or a controller-drive tray requires
that each host adapter attach to a different controller.
ATTENTION Possible loss of data access – You must install alternate path software or an alternate
path (failover) driver on the host to support failover in the event of an HBA failure or a host channel failure.

Drive Cabling
This chapter provides examples of cabling between a controller tray or a controller-drive tray and the
environmental services monitors (ESMs) of one or more expansion drive trays. This chapter also shows
potential combinations of these products in storage array configurations.
IMPORTANT Every example in this chapter provides redundant access to each drive.
See the topics under “Component Locations” for drive port locations on the specified controller tray or
controller-drive tray and drive tray models that you are installing.
Refer to the section that applies to the controller tray or controller-drive tray to which you are cabling the drive
trays.
Drive Channel Redundancy for the CE7900 Controller Tray and the CE7922
Controller Tray
Each controller has four drive channels, and each drive channel has two ports. Therefore, each controller
has eight drive ports. A controller tray has eight redundant path pairs that are formed using one drive channel
of controller A and one drive channel of controller B. The following figure shows the redundant pairs in a
controller tray. The following table lists the numbers of the redundant path pairs and the drive ports of the
drive channels from which the redundant path pairs are formed.
IMPORTANT To maintain data access in the event of the failure of a controller, an ESM, or a drive
channel, you must connect a drive tray or multiple drive trays on a loop to both drive channels on a redundant
path pair.
IMPORTANT If you are connecting DE6900 drive trays and you plan to use the drive-side trunking
capability, you must connect each drive tray (or multiple drive trays on a loop) to both drive channels on each
of two redundant path pairs to maintain hardware redundancy.

One CE7922 or CE7900 Controller Tray and Nine to 16 FC4600 Drive Trays
When the number of drive trays exceeds eight, the cabling pattern changes significantly. From this point, you
will begin to use the “A” ports on the ESMs, and connect the drive trays beyond the eighth one to another
drive tray.
If you add drive trays to an existing configuration so that the total number of drive trays attached to one
controller tray increases from eight or fewer to a total of more than eight, you must re-cable some of the drive
trays that were previously cabled to that controller tray. For each new drive tray beyond the eighth one, in
addition to adding two cables to attach the new drive tray, you must move one cable on a previously installed
drive tray.
The following figure and table show an example where a ninth and tenth drive tray have been added
to a controller tray that previously had eight drive trays. Cable 1 remains the same as in the previous
configuration. The end of cable 2 that was previously connected to drive tray 1 now connects to drive tray 9.
Cables 17 and 18 are added between drive tray 1 and drive tray 9 so that they now connect in series. Drive
tray 10 is added using connections to drive tray 2 that follow the pattern of the connections between drive tray
1 and drive tray 9. Drive tray 3 is not connected to another drive tray, so its cabling remains the same (as it
does for drive trays 4 to 8, which do not appear in the table).
You can cable up to 16 drive trays by following the pattern shown in this example.

One CE7922 or CE7900 Controller Tray and 17 to 28 FC4600 Drive Trays
You can add drive trays in series to each redundant pair of drive ports up to 28 drive trays. In a configuration
with 28 drive trays, four of the port pairs will have four drive trays each, while the other four will have three
drive trays each. The following figure shows this arrangement schematically. The physical arrangement of the
drive trays in cabinets will depend on your particular installation.
The following table shows an example cabling pattern for adding three drive trays (drive trays 9, 17, and 25)
in series with drive tray 1. Add drive trays in series to each redundant pair of drive ports so that the number
of drive trays for each pair of drive ports remains balanced, to the extent possible. For example, do not add a
third drive tray in series with drive tray 1 on ports 8 and 1 if another pair of drive ports has only one drive tray
connected.

One CE7922 or CE7900 Controller Tray and One to Four DE6900 Drive Trays without Trunking
In the cabling configuration figures that follow, the controller tray is placed on top, and the controllers are
labeled as A and B. Because the DE6900 drive trays are very heavy, they are installed starting at the bottom
of the cabinet. The drive trays are labeled from the bottom upward as 1, 2, 3, and so on. The figures in this
section show representative configurations for cabling.
NOTE The CE7900 controller tray and the DE6900 drive trays do not have to be stacked in this exact
order, and there is no requirement that you label the drive trays in this particular sequence. Just make sure
that the DE6900 drive trays are at the bottom of the cabinet.
One CE7900 Controller Tray and Four DE6900 Drive Trays without Trunking
The following table specifies the cabling pattern for a controller tray that is attached to one to four drive trays.
The “Cable” column indicates that two cables are used for each drive tray. In the rows for cable 1 and cable
2, for example, the “Xs” indicate that the cables are connected to controller A, channel 1, port 8 and controller
B, channel 5, port 1 respectively. The “Bs” in these rows indicate that the other ends of cable 1 and cable
2 are connected to port 1B of the top ESM (ESM A) and port 1B of the bottom ESM (ESM B) of drive tray 1
respectively. This pattern continues, using even-numbered ports on controller A and odd-numbered ports on
controller B for the first four drive trays.

Use the configuration examples in this section as a guide to configure your storage array to receive the
benefits of drive-side trunking cabling. Drive-side trunking uses the right side of the expansion ports on the
rear of the drive trays to allow the full bandwidth potential of the CE7900 controller tray.
Drive-side trunking requires that the ESMs have four ports to support trunked cascading connections to other
drive trays. These cascading connections only apply when eight DE6900 drive trays are connected to a single
controller tray.
The figures in this section show representative configurations for cabling.

One CE6998 Controller Tray and Multiple Types of Drive Trays
If you are cabling more than one type of drive tray to the CE6998 controller tray, read these topics before you
choose a cabling topology:
SANtricity_10.77 February 2011
LSI Corporation
- 622 -
Guidelines for Cabling FC2610 Drive Trays or FC4600 Drive Trays
Guidelines for Cabling AT2655 Drive Trays
Follow these guidelines for cabling multiple types of drive trays to maximize performance and accessibility.
Guidelines for Cabling FC2610 Drive Trays or FC4600 Drive Trays
Follow these guidelines for cabling a topology with multiple types of drive trays, including the FC2610 drive
trays or the FC4600 drive trays.
If your storage array includes FC2610 drive trays or FC4600 drive trays, cable the FC2610 drive trays
or the FC4600 drive trays so that they are the first devices on the drive channel (after controller A). The
first device on the drive channel is distinguished by the fact that the left ESM of the first device is cabled
directly to controller A of the controller tray. Because an optimal redundant cabling topology requires that
the redundant drive channel be cabled in the opposite order, this same device will be the last in the drive
channel when cabled to controller B.
Evenly distribute the FC2610 drive trays or the FC4600 drive trays in pairs or multiples across redundant
pairs of the available drive channels.
Do not cable a single FC2610 drive tray or a single FC4600 drive tray on a drive channel unless it is the
only FC2610 drive tray or FC4600 drive tray in the storage array.
Guidelines for Cabling AT2655 Drive Trays
Follow these guidelines for cabling a topology with multiple drive tray types, including AT2655 drive trays.
If your storage array includes AT2655 drive trays, cable the AT2655 drive trays so that they are the last
devices on the drive channel (from a top-down cabling perspective).
Distribute AT2655 drive trays across redundant pairs of drive channels to equalize the number of drive
trays on the available channels.
In the following figure, the FC2610 drive trays and the FC4600 drive trays are identified as SBODs (Switched
Bunch of Disks). The AT2655 drive tray is identified as SATA (Serial Advanced Technology Attachment).
IMPORTANT When you mix different types of drive trays, you must consider the total number of drives
that are available in the final configuration of the storage array. For example, if you mix FC4600 drive trays
with FC2610 drive trays, the total number of drives might be more than the maximum number that each drive
channel can support.

Drive Cabling Topologies for the CDE3994 Controller-Drive Tray and the
CDE3992 Controller-Drive Tray
This section provides examples of drive cabling topologies that can be used for the CDE3994 controller-drive
tray. The controllers on the lower-cost CDE3992 controller-drive tray have two host ports and two drive ports.
The controllers on the higher-cost CDE3994 controller-drive tray have four host ports and two drive ports.
Each example provides redundant paths to the drives. If one of these examples is suitable for your hardware
and application, complete the cabling connections as described by the tables. However you decide to
implement your cabling, follow the recommendations in the "Best Practices" topic to ensure full availability of
data.

by the firmware.
NOTE If you have drive trays with side-by-side ESM canisters, see “ESM Canister Arrangements.”
One CDE3994 Controller-Drive Tray or CDE3992 Controller-Drive Tray and Multiple Types of
Drive Trays
If you are cabling more than one type of drive tray to the CDE3994 controller-drive tray, be sure to read these
topics before you choose a cabling topology:
“Multiple Types of Drive Trays”
“Cabling for Drive Trays That Support Loop Switch Technology”
Follow these guidelines for cabling multiple types of drive trays to maximize performance and accessibility.
(The first device on the drive channel is distinguished by the fact that the left ESM of the first device is cabled
directly to controller A of the controller tray or controller-drive tray. Because an optimal redundant cabling
topology requires that the redundant drive channel be cabled in the opposite order, this same device will be
the last in the drive channel when cabled to controller B.)

The following figure provides an example of how flexible the cabling can be when you use a CDE3994
controller-drive tray as the controller. The firmware is able to detect, and correctly handle, combinations of
drive trays with both side-by-side ESMs and inverted ESMs. This feature allows you to easily add new drive
trays to your storage environment, while continuing to take advantage of pre-existing drive trays that you own.
If your storage array includes AT2655 drive trays, it is still advisable to cable the AT2655 drive trays so that
they are the last devices on the drive channel (farthest from controller A).
IMPORTANT When you mix different types of drive trays, you must consider the total number of drives
that are available in the final configuration of the storage array. For example, if you mix FC4600 drive trays
with FC2610 drive trays, the total number of drives might be more than the maximum number that each drive
channel can support.

Ethernet Cabling
This chapter provides examples of how to connect your storage array to an Ethernet network for out-of-band
storage array management. If you plan to use in-band storage array management, Ethernet cabling might not
be necessary for management connections.
For illustrations showing the Ethernet port locations on the specific controller tray model or controller-drive
tray model that you are installing, see the topics under “Component Locations.”
ATTENTION Possible loss of data access – If you use out-of-band management, connect the
Ethernet ports on the controller tray or the controller-drive tray to a private network segment behind a firewall.
If the Ethernet connection is not protected by a firewall, your storage array might be at risk of being accessed
from outside of your network.
Direct Out-of-Band Ethernet Topology
The following figure shows storage array management connections from the controller tray or controller-
drive tray to the Ethernet. In this topology, you must install a network interface card (NIC) in the storage
management station in which the client software resides. For dual controllers, you must install two NICs in the
storage management station.
NOTE For more information about NICs, see “Network Interface Cards.”
Network Out-of-Band Ethernet Topology
IMPORTANT In limited situations where the storage management station is connected directly to the
controller tray or the controller-drive tray, you must use an Ethernet crossover cable to connect the storage
management station to the Ethernet port. An Ethernet crossover cable is a special cable that reverses the pin
contacts between the two ends of the cable.

Fabric Out-of-Band Ethernet Topology
The following figure shows two storage array management connections from the controller tray or the
controller-drive tray to two ports on an Ethernet switch. In this topology, you must install a NIC in the storage
management station where the client software resides. You must use Ethernet cables for all storage array
management connections.
Fabric Redundant Out-of-Band Ethernet Topology
For more information, see “In-Band Management and Out-of-Band Management.”
IMPORTANT If you have two available Ethernet ports on each controller, reserve one port on each
controller for access to the storage array by your Customer and Technical Support representative.

Component Locations
This chapter provides shows the rear of each controller tray, controller-drive tray, and drive tray. The figures
identify the locations of controllers, environmental services monitors (ESMs), host ports, drive ports, and
Ethernet ports. The figures also show port identifiers.
Use the figures in the following topics to make sure that you have correctly identified the cable connection
points described under "Host Cabling," "Drive Cabling," and "Ethernet Cabling."
Port Locations on the CE7922 Controller Tray and the CE7900 Controller Tray
The CE7922 and CE7900 controller trays have host channels that you can attach to the hosts, and drive
channels that you can attach to the drive trays. The examples in this section show the CE7900 controller tray.
The port locations are the same for the CE7922 controller tray.
Each of the two controllers in the CE7900 controller tray might have two host cards with four host ports on
each card. This configuration is shown in the following figure. Some CE7900 controller trays might have
controllers with only one host card each.
Controller A is inverted from controller B, which means that its host channels are upside-down.
Host Channels on the CE7922 and CE7900 Controller Trays – Rear View

tray is available in two different controller configurations: simplex and duplex.
Keep these points in mind when you compare the figures in this section to your hardware.
The top of the controller-drive tray is the side with the labels.
The configuration of the host ports depends on which host interface card configuration is installed.
The figures in this section show the AC power option.
NOTE On the CDE2600 controller-drive tray, each controller has a pair of levers with handles for
removing the controller from the controller-drive tray. If a controller has a HIC installed, one of these handles
on the controller is located next to a host port on the HIC. The close spacing between the handle and the host
port might make it difficult to remove a cable that is attached to the host port. If this problem occurs, use a flat-
blade screwdriver to compress the release on the cable connector.

Adding a Drive Tray to an Existing System
This chapter provides information about adding a drive tray to an existing system.
Getting Ready
If you need to add another drive tray to an existing storage array, contact your Customer and Technical
Support representative before proceeding. Your Customer and Technical Support representative might direct
you to complete preparatory tasks before installing and cabling the new drive tray. Some of these tasks might
include:
Creating, saving, and printing a storage array profile for all of the storage arrays that will be affected by
the upgrade
Performing a complete backup of all of the drives in the storage array
Making sure that the volume groups and associated volumes on the storage array have an Optimal status
ATTENTION Possible loss of data access – Contact your Customer and Technical Support
representative if you plan to add a drive tray to an existing storage array under either of the following
conditions: The power is not turned off to the controller tray or the controller-drive tray or data transfer
continues to the storage array.
HotScale Technology
HotScale™ technology lets you configure, reconfigure, add, or relocate storage array capacity without
interrupting user access to data.
Port bypass technology automatically opens ports and closes ports when drive trays are added to or removed
from your storage array. Fibre Channel loops stay intact so that system integrity is maintained throughout the
process of adding and reconfiguring your storage array.
For more information about using the HotScale technology, contact your Customer and Technical Support
representative.
Adding Redundant Drive Channels
If you are working with a storage array that has redundant drive channels, it is easy to add drive trays. Make
sure that you always maintain communication between a functioning controller and the existing drive trays
by only interrupting the continuity of a single drive channel at any one point in time. This precaution avoids
interruption of data availability.
Your Customer and Technical Support representative can provide assistance in maintaining access to data
during the upgrade of your storage array.
Adding One Non-Redundant Drive Channel
If you are working with a storage array that has only one drive channel, add the drive tray to the end of the
series of drive trays in the storage array. You do so while power is still applied to the other drive trays.
SANtricity_10.77 February 2011

ATTENTION Risk of equipment damage – If your FC4600 drive tray, DE1600 drive tray, or DE5600
drive tray uses the optional DC power connection, a different procedure exists for turning on and turning off
the power to a DC-powered drive tray. Refer to the topics under Storage Array Installation for the hardware
you are installing or refer to the corresponding PDF document on the SANtricity ES Storage Manager
Installation DVD.
1. Add the new drive tray to the end of the series of existing drive trays.
2. Install the additional cable.
3. Turn on the power to the new drive tray.

Hardware Installation for Remote Volume Mirroring
This appendix provides information about these topics:
Site preparation
Hardware requirements
Cabling
Review this information and complete the steps before starting any hardware installation procedures. Refer to
the online help system for background information on the Remote Volume Mirroring (RVM) premium feature
and for software-related procedures to set the configuration of the feature and use it.
Site Preparation
The RVM premium feature can be used only with Fibre Channel host connections. You must have Fibre
Channel switches to use RVM and to create a fabric environment for data replication. These switches require
only minimal additional site preparation requirements beyond basic storage array operation.
For additional site preparation considerations for Fibre Channel switches, including power requirements
and physical dimensions and requirements, refer to the documentation that is provided by the switch
manufacturer.
Switch Zoning Overview
Because of possible restrictions at the host level, the supported Remote Volume Mirroring configurations
contain Fibre Channel switches. These Fibre Channel switches are zoned so that a single host adapter can
access only one controller per storage array. Additionally, all configurations use a separate zone for the ports
that are reserved for the Remote Volume Mirroring premium feature.
IMPORTANT Do not zone the uplink port (E_port) that connects (cascades) switches within a fabric.
Switch zoning configurations are typically set up by using the switch management software that is provided
by the manufacturer of the Fibre Channel switch. This software should have been included with the materials
that are provided when the switch was purchased.
When two or more Fibre Channel switches are cascaded together, the switch management software
combines the ports for all of the switches that are linked. For example, if two 16-port Fibre Channel switches
are cascaded with a physical connection using a Fibre Channel cable, the switch management software
shows ports 0 through 31 participating in the fabric rather than two switches each with ports 0 through 15.
Therefore, a zone that is created containing any of these ports can exist on multiple cascaded switches.
The following figure shows both cascaded and non-cascaded switches. The top-half of the figure shows a set
of cascaded switches that are on the same network. Therefore, Zone 1 is the same zone on Switch 1A as
Zone 1 is on Switch 1B. In a single-mode Fibre Channel environment, the two switches are connected by a
single port on each switch that is designated as an E_port, which is not in a zone.
The set of switches in the bottom half of the following figure is on the same network but is not cascaded.
Although both sets contain a Zone 1 (shown as Zone A in Switch 2), these zones are independent of each
other.

Switch Zoning in Cascaded and non-Cascaded Fibre Channel Switches
For more information about Fibre Channel switch zoning or setting up a zone configuration, refer to the
manufacturer’s documentation that is provided with the switch.
Because of the varying Remote Volume Mirroring configurations, the switch zone settings are presented
preceding each configuration in this appendix.
Hardware Installation
Select one of the following configuration options to connect and configure one or more storage arrays for use
with the Remote Volume Mirroring premium feature.

Configuration Options for Remote Volume Mirroring
Configuration Description
Highest availability
campus configuration
(recommended)
This configuration has the greatest redundancy. It is the most stable of
the three configurations.
Two Fibre Channel switches (for a total of four) at both the primary
site and the secondary site provide for complete failover and
redundancy in the Fibre Channel switches and fabrics, in addition
to all storage array components and hosts.
A single point of failure does not exist in this configuration, and it is
the recommended configuration for the Remote Volume Mirroring
premium feature.
Go to "Highest Availability Campus Configuration – Recommended.”
Campus
configuration The campus configuration is a lower-cost configuration than the
highest availability campus configuration. Only one Fibre Channel
switch at the primary site and one at the secondary site exist, for a
total of two switches. This configuration essentially allows the minimum
required components to successfully operate the Remote Volume
Mirroring premium feature between two sites.
The number of Fibre Channel switches is reduced from four to two
and the number of fabrics from two to one.
This configuration is redundant for host bus adapters, controllers,
and Remote Volume Mirroring ports, but it has a single point of
failure for switches and fabric.
A switch failure does not usually result in a loss of data, but it does
affect data synchronization until the error is corrected. Therefore,
the highest availability campus configuration is the recommended
configuration, because data synchronization can continue for any
single switch failure.
Go to “Campus Configuration.”
Intra-site
configuration The intra-site configuration is the lowest-cost configuration of all three
configurations. It is used in environments where a long-distance fabric
is not required because of the close proximity of the hosts and storage
arrays.
Because the intra-site configuration only has two switches, it is
similar to the campus configuration. However, multiple-switch
fabrics do not exist in this configuration.
The configuration is redundant for host bus adapters, controllers,
Remote Volume Mirroring ports, and switches but is a single
point of failure for the site because all of the equipment can be
destroyed by the same disaster.
The highest availability campus configuration is the recommended
configuration, because it is fully redundant, which makes disaster
recovery easier.
Go to “Intra-Site Configuration.”

Highest Availability Campus Configuration – Recommended
NOTE The highest availability campus configuration is the recommended configuration for the Remote
Volume Mirroring premium feature.
This configuration has two Fibre Channel switches at the primary site and two Fibre Channel switches
at the secondary site (four switches total), which provide for complete failover and redundancy. Failures
could involve Fibre Channel switches, Fibre Channel cables, and any host or storage array. Two Fibre
Channel switches at each site also provide redundancy to the local site in addition to a fully redundant remote
configuration. No single point of failure exists in the hardware components.
The following figure shows the highest availability campus configuration. The controller trays are shown
schematically with four host ports on each of two controllers in each controller tray. In this configuration, use
the A4 connection and the B4 connection for remote mirroring traffic instead of the A2 connection and the B2
connection. You can use controller ports A2, A3, B2, and B3 for additional host access if needed.

Switch Zoning for Highest Availability Campus Configuration
The highest availability campus configuration provides a separate zone for each reserved port for the Remote
Volume Mirroring premium feature.
The switches do not need to be zoned exactly as presented in this configuration. However, you must meet the
following requirements when zoning switches for the highest availability campus configuration.
There are a total of four zones in this configuration.
Zone 1 and zone 3 are on fabric 1 (switch 1A at the primary site, and switch 1B at the secondary site).
Zone 2 and zone 4 are on fabric 2 (switch 2A at the primary site, and switch 2B at the secondary site).
SANtricity_10.77 February 2011
LSI Corporation
- 675 -
Configure the zones on the switch so that there is one port per zone for a storage array connection and one
port per zone for each host. Switches are zoned so that a single host bus adapter port can access only one
controller per storage array.
Switches are zoned so that a single host bus adapter port can access only one controller for each storage
array.
NOTE Do not zone the uplink ports (E_ports) on any of the Fibre Channel switches.
The following figure shows how the four switches are zoned for the highest availability campus configuration.
The switches have 16 ports each, which leaves unused ports on each switch when following the preceding
requirements. The remaining ports can be distributed among the other zones. It is recommended, however,
that most of the remaining ports be assigned to the zones containing the host connections: zone 1 and zone
2. This port assignment allows easy setup for additional hosts to connect to the environment.
Switch Zoning for the Highest Availability Campus Configuration
Before you proceed, review the requirements listed in this section and the zoning shown in the figure to make
sure that all four switches are correctly zoned. For more information, see the “Switch Zoning Overview.”
Cabling for the Highest Availability Campus Configuration
IMPORTANT Start the installation at the primary site. Repeat these steps for the secondary site when
instructed to do so.
After the four Fibre Channel switches are correctly zoned, complete this procedure to set up the highest
availability campus configuration for the Remote Volume Mirroring premium feature.
NOTE Complete all connections by using Fibre Channel cables of the correct length.
1. Are you adding equipment for the Remote Volume Mirroring premium feature to an existing storage array
environment?
Yes – Stop I/O activity from all hosts before proceeding. Go to step 2.
No – The storage array installation is new. Go to step 3.

primary site and switch 1B for the secondary site. This representation applies to switch 2 as well.
4. Connect the primary host bus adapter for each local host to an available port in zone 1 of switch 1.
The following figure shows the cabling that is described in step 4 and step 5.
Host Bus Adapter Connections to Fibre Channel Switches
NOTE You can connect the cables to any port in the correct zone of the switch for all of the
controller trays except the CE6998 controller tray. Host port 4 on each controller of the CE6998 controller
trays is reserved for using the Remote Volume Mirroring premium feature. If you are not using the
Remote Volume Mirroring premium feature, host port 4 on a CE6998 controller tray is available for host
connections.
5. Connect the secondary host bus adapter for each host at this site to an available port in zone 1 of
switch 2.

both sites where the power was turned off.
The hardware installation is complete. To configure the storage management software to support mirror
relationships, refer to the online help topics.
Campus Configuration
The campus configuration offers the same functionality as the highest availability campus configuration, but
the campus configuration contains only one switch at each site, rather than two. The configuration is still
redundant for host bus adapters, controllers, and remote mirroring ports, but the configuration has a single
point of failure for switches. If a switch at either site fails, the Remote Volume Mirroring premium feature
cannot operate. For this reason, the highest availability campus configuration is highly recommended for total
environment redundancy.
The following figure shows a complete campus configuration. The controller trays are shown schematically
with four host ports on each of two controllers in each controller tray.

Intra-Site Configuration
The intra-site configuration is used in environments where a long-distance fabric is not required because of
the close proximity of the hosts and storage arrays. The configuration is still redundant for host bus adapters,
controllers, remote mirroring ports, and switches, but the configuration is a single point of failure for the site
because all of the equipment can be destroyed by the same disaster. For this reason, the highest availability
campus configuration is highly recommended for total environment redundancy.
The following figure shows a complete installation of the intra-site configuration.
IMPORTANT A switch failure in this configuration does not affect data access; however, as a result, an
Unsynchronized state might occur for all of the mirror relationships on both the primary storage arrays and the
secondary storage arrays.

Switch Zoning for the Intra-Site Configuration
The intra-site configuration provides switch redundancy, but the switches are not cascaded and are
independent of each other.
NOTE The switches do not need to be zoned exactly as presented in this configuration. However, you
must meet the following requirements when zoning switches for the intra-site configuration.
You must have a total of four zones on each controller in this configuration.
You must configure the zones on the switch so that there is one port per zone for a storage array connection
and one port per zone for each host.
You must zone the switches so that a single host adapter can only access one controller per storage array.
The switches in the following figure contain 16 ports each, which leaves many unused ports per switch.
The remaining ports can be distributed among the other zones. However, it is recommended that most of
the remaining ports be assigned to the zones containing the host connections: zone 1 and zone 2. This
assignment allows for easy setup for connecting additional hosts.

Installing and Using Remote Volume Mirroring with a Wide Area Network
When installing and using the Remote Volume Mirroring premium feature over a wide area network (WAN),
keep these guidelines in mind:
If you are setting up an FCIP router to perform asynchronous Remote Volume Mirroring, go to the
Compatibility Matrix. Select Router-FCIP in the Product field, and select the release of the storage
management software that you use in the Software Release field. Verify that the maximum latency
and distance are supported by referring to the vendor specifications for your router and by checking the
Compatibility Matrix. The Compatibility Matrix is found at http://www.lsi.com/compatibilitymatrix/.
FCIP router vendors and telecommunication vendors are responsible for setting up routing.
The smaller the bandwidth on the WAN, the longer it takes an asynchronous mirror to synchronize.
If the bandwidth does not exceed the average rate, you might not be able to synchronize the data at all.
For example, if the system writes at 1 Mb/s, it needs 2 Mb/s of bandwidth available.
If the mirroring is lagging far behind during production hours, suspend the mirror. During off-peak hours,
resume the mirror.
SANtricity_10.77 February 2011
LSI Corporation
- 689 -
If you need to keep the Remote Volume Mirroring on at all times, keep the mirror physically as close as
possible to the production site.
To determine the average write rate, you should use the available system utilities and should take
measurements during peak times.
If you anticipate adding any applications, determine the bandwidth needs for any future applications.
Acceptable lag times vary depending on the environment and should be determined on an individual
basis.
Line Capacities

The following table shows average write operations in Mb/s with corresponding line capacity calculations.
When the line capacity calculation is below 50 percent, the result is an adequate response-time performance
and a limited need for delta logging (when the mirror lags behind the data). When the line capacity calculation
is above 50 percent, the mirror can never catch up. Any transfers above 50 percent will start to lag.

Step 1 – Deciding on the Management Method
You can manage a storage array using the in-band method, the out-of-band method, or both.
IMPORTANT You need to know the storage management method that you plan to use before you
install the software, connect the cables, and use the storage management software.
Key Terms
access volume
A special volume that is used by the host-agent software to communicate management requests and event
information between the management station and the storage array. An access volume is required only for in-
band management.
Dynamic Host Configuration Protocol (DHCP)
CONTEXT [Network] An Internet protocol that allows nodes to dynamically acquire ('lease') network
addresses for periods of time rather than having to pre-configure them. DHCP greatly simplifies the
administration of large networks, and networks in which nodes frequently join and depart. (The Dictionary of
Storage Networking Terminology)
in-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands to the storage
array through the Ethernet connections on the controller.
stateless address autoconfiguration
A method for setting the Internet Protocol (IP) address of an Ethernet port automatically. This method is
applicable only for IPv6 networks.
World Wide Identifier (WWID)
CONTEXT [Fibre Channel] A unique 64-bit number assigned by a recognized naming authority (often using
a block assignment to a manufacturer) that identifies a node process or node port. A WWID is assigned for
the life of a connection (device). Most networking physical transport network technologies use a world wide
unique identifier convention. For example, the Ethernet Media Access Control Identifier is often referred to as
the MAC address. (The Dictionary of Storage Networking Terminology)
Steps to Decide – Management Method
IMPORTANT If you use the out-of-band management method but do not have a DHCP server, you
must manually configure your controllers. See “Step 10 – Manually Configuring the Controllers” for details.
1. Use the key terms and the following figures to determine the management method that you will use.
2. After reading the information in this section, add a check mark next to the management method that you
will use.

1. Show a list of unconfigured iSCSI initiators.
2. Create an iSCSI initiator.
3. Set the iSCSI initiator.
4. Set the iSCSI target properties.
5. Show the current iSCSI sessions.
Procedure – Configuring and Viewing the Targets
Configure a target and, optionally, persist that target. You must configure each port on the target one time. If
you are using Challenge-Handshake Authentication Protocol (CHAP), you can also establish a CHAP user
name and password when you configure the target.
1. If you are not using CHAP, type this command for each port on the target from the command line:
iscsicli QAddTargetPortal <IP Address Target Controller>
In this command, <IP Address Target Controller> is the IP address for the target port that you
are configuring.
2. If you are using CHAP, type this command for each port on the target from the command line:
iscsicli QAddTargetPortal <IP Address Target Controller> <CHAP Username> <CHAP Password>
In this command:
<IP Address Target Controller> is the IP address for the target port that you are configuring.
<CHAP Username> and <CHAP Password> are the optional user name and password for the target
port that you are configuring.
3. After you have configured all of the ports on the target, you can show a list of all configured targets. From
the command line, type this command:
iscsicli ListTargets
A list of all found targets appears.

Procedure – Establishing a Persistent Login to a Target
You can establish a persistent login to a target. A persistent login is the set of information required by an
initiator to log in to the target each time the initiator device is started. The login usually occurs when you start
the host. You cannot initiate a login to the target until after the host has finished rebooting. You must establish
a persistent login for each initiator-target combination or initiator-target path. This command requires 18
parameters. Several of the parameters use the default values and are indicated with *. Refer to the Microsoft
iSCSI Software Initiator 2.x Users Guide for a description of this command and the parameters.
From the command line, type this command:
iscsicli PersistentLoginTarget <Target Name> <ReportToPNP> <TargetPortalAddress>
<TCPPortNumberofTargetPortal> * * * <Login Flags> * * * * * * * * * <MappingCount>
In this command:
<Target Name> is the name of your target port as shown in the targets list.
<ReportToPNP> is set to T, which exposes the LUN to the operating system as a storage device.
<TargetPortalAddress> is the IP address for the target port.
<TCPPortNumberofTargetPortal> is set to 3260, which is the port number defined for use by iSCSI.
<Login Flags> is set to 0x2, which allows more than one session to be logged into a target at one
time.
<MappingCount> is set to 0, which indicates that no mappings are specified and no further parameters
are required.
* uses the default value for that parameter.
IMPORTANT To make sure that your configuration settings take effect, you must reboot the host before
continuing with these tasks.
Procedure – Verifying Your iSCSI Configuration
After you reboot the host, you can verify your configuration.
From the command line, type this command:
iscsici ListPersistentTargets
A list of persistent targets configured for all iSCSI initiators appears. Make sure that “Multipath Enabled”
appears in the output under Login Flags.
Procedure – Reviewing Other Useful iSCSI Commands
The commands listed in this section are useful for managing the iSCSI targets and iSCSI initiators.
This command shows the set of target mappings assigned to all of the LUNs to which all of the iSCSI initiators
are logged in.

Procedure – Installing the SANtricity ES Storage Manager Software
IMPORTANT Make sure that you have the correct administrator or superuser privileges to install the
software.
1. Insert the SANtricity ES Storage Manager Installation DVD in the DVD drive.
Depending on your operating system, a program autoplays and shows a menu with installation selections.
If the menu does not appear, you must perform these tasks:
a. Manually open the install folder.
b. Locate the installation package that you want to install.
2. Install the software installation packages that are required for your storage configuration.
You might be required to open a window or terminal to run one of these commands.
hsw_executable.exe -i console
hsw_executable.exe -i silent
In the commands, hsw_executable.exe is the file name for the storage management software
installation package.
When using the console parameter during the installation, questions appear on the console that
enable you to choose installation variables. This installation does not use a graphical user interface
(GUI). Contact your Customer and Technical Support representative if you need to change the
installation options.
When using the silent parameter during the installation, the command installs the storage
management software using all of the defaults. A silent installation uses a resource file that contains
all of the required information, and it does not return any windows until the installation is complete.
This installation does not use a GUI. Contact your Customer and Technical Support representative if
you need to change the installation options.
Example: These examples show the actual command used to launch the installation wizard for a particular
operating system.

Windows operating systems – Double-click the executable file. In general, the executable file begins
with SMIA followed by the operating system name, such as SMIA-WS32.exe.
UNIX operating systems – At the command prompt, type the applicable command to start the installer,
and press Enter. For example, type a command that is similar to this command: sh DVD_name.bin. In
this command, DVD_name.bin is the name of the installation DVD, such as SMIA-LINUX.bin.
NOTE If necessary, set the display environment to issue the command.
Example: Use the information in the on-screen instructions to install the software.
Things to Know – Software Packages
Client – This package contains the graphical user interface for managing the storage array. This package
also contains a monitor service that sends alerts when a critical problem exists with the storage array.
NOTE You can add from one to eight clients to your storage configuration.
Utilities – This package contains utilities that let the operating system recognize the volumes that you create
on the storage array and to view the operating system-specific device names for each volume.
Agent – This package contains software that allows a management station to communicate with the
controllers in the storage array over the I/O path of a host (see “Things to Know – In-Band and Out-of- Band
Requirements.”)
Failover driver – This package contains the multi-path driver that manages the I/O paths into the controllers
in the storage array. If a problem exists on the path or a failure occurs on one of the controllers, the driver
automatically reroutes the request from the hosts to the other controller in the storage array.
Java Access Bridge (JAB) – This package contains accessibility software that enables Windows-based
assistive technology to access and interact with the client application.
Support Monitor Profiler – This package gathers, records, and communicates data about the operation of
a storage array. The application is installed with the SANtricity ES Storage Manager if you choose either a
Typical or Management Station Installation.
NOTE The Microsoft Virtual Disk Service (VDS) and Volume Shadow Copy Service (VSS) providers
are a part of the SANtricity ES Storage Manager package for the Windows Server 2003 OS and the Windows
Server 2008 OS.
NOTE Use the figures and tables that follow to determine the software packages that should be
installed on each machine.
IMPORTANT You must install the utilities and the failover driver on each host that is attached to the
storage array.
IMPORTANT If you choose not to automatically enable the event monitor during installation, you will
not receive critical alert notifications.
SANtricity_10.77 February 2011
LSI Corporation

IMPORTANT During the client installation, you are asked whether you want to start the monitor. Start
the monitor on only one host that runs continuously. If you start the monitor on more than one host, you
receive duplicate alert notifications about problems with the storage array.

Step 4 – Configuring the Host Bus Adapters
Procedure – Configuring the HBAs
A host bus adapter (HBA) is an adapter on the information bus of the host computer. This adapter acts as a
bridge and provides connectivity between both the host computer and the storage. Host bus adapters free
up critical server processing time. Depending on the configuration of your storage array, you must set up the
HBA to enable storage access using Fibre Channel, iSCSI or SAS connections.
This section provides information about configuring HBA settings for your Fibre Channel (FC) connections.
For information about configuring HBA settings for iSCSI and SAS connections, refer to the latest Product
Release Notes for SANtricity ES Storage Manager .
For the latest compatibility information about recommended HBA settings for FC, iSCSI, and SAS
connections, refer to the Storage Systems Compatibility Matrix, available at:
http://www.lsi.com/compatibilitymatrix/

Overview electronic document topics or to the PDF on the SANtricity ES Storage Manager Installation DVD.
Retrieving Trace Buffers
Use the Advanced >>Troubleshooting >> Support Data >> Retrieve Trace Buffers option to save
trace information to a compressed file. The firmware uses the trace buffers to record processing, including
exception conditions, that might be useful for debugging. Trace information is stored in the current buffer. You
have the option to move the trace information to the flushed buffer after you retrieve the information. (The
option to move the trace information to the flushed buffer is not available if you select Flushed buffer from
the Trace Buffers list.) Because each controller has its own buffer, there might be more than one flushed
buffer. You can retrieve trace buffers without interrupting the operation of the storage array and with minimal
effect on performance.
NOTE Use this option only under the guidance of your Customer and Technical Support representative.

Step 9 – Adding Controller Information for the Partially Managed
Storage Array
IMPORTANT You only need to perform this step if you have partially managed storage arrays.
Key Terms
partially managed storage array
A condition that occurs when only one controller is defined or can be reached when the storage array is
added to or found by the storage management software. In this case, volume management operations can
be done only on volumes owned by the reachable controller. Many other management operations that require
access to both controllers are not available.
Things to Know – Partially Managed Storage Arrays
You can identify a storage array as a partially managed storage array if you see these indications for the
storage array:
When you close the Add New Storage Array – Manual dialog after adding the storage array, a Partially
Managed Storage Arrays dialog appears.
When you try to manage the storage array using the Array Management Window, a Partially Managed
Storage Arrays dialog appears.
When you select View >> Partially Managed Storage Arrays, the storage array is listed in the Partially
Managed Storage Arrays dialog.
When you place the cursor on the storage array, “partially managed” appears in the tooltip.
NOTE The tooltip indication appears only for out-of-band storage arrays.
Procedure– Automatically Adding a Partially-Managed Storage Array
NOTE These steps are for out-of-band partially managed storage arrays only. For in-band partially
managed storage arrays, verify the connection, and perform the steps in “Procedure – Rescanning the Host
for a New Storage Array” to rescan the host.
1. From the Enterprise Management Window, select View >> Partially Managed Storage Arrays.
2. Select the required partially managed storage array from the list of storage arrays.
3. Click Add More to add the information about the second controller.
The Add New Storage Array – Manual dialog appears.
4. Manually enter the host names or the IP addresses of the controllers (out-of-band management method)
or the host name or IP address of the host running the host-agent software (in-band management
method), and click Add.
The storage array appears in the Enterprise Management Window.
NOTE You can enter IP addresses in either the IPv4 format or the IPv6 format.

Step 10 – Manually Configuring the Controllers
Things to Know – Manually Configuring the Controllers
IMPORTANT You need to perform this step only if you want to use the out-of-band management
method and you do not have a DHCP server to automatically assign IP addresses for the controllers.
See “Step 1 – Deciding on the Management Method” to determine if you need to make any configuration
changes to the controller.
In general, Ethernet port 1 on each controller is used for storage management, and Ethernet port 2 on
each controller is used by the Customer and Technical Support representative.
You should configure Ethernet port 2 only if your Customer and Technical Support representative asks
you to do so.
You can configure a gateway on only one of the Ethernet ports on each controller.
Ethernet port 1 and Ethernet port 2 must be on different sub-networks.
You can select one of the following speed and duplex mode combinations for your Ethernet ports. If
you select the auto-negotiate option, the controller will use the highest speed supported by the Ethernet
connection.
Supported Speed and Duplex Mode Combinations
Speed Duplex Mode
1000BASE-T Duplex
1000BASE-T Half Duplex
100BASE-T Duplex
100BASE-T Half Duplex
10BASE-T Duplex
10BASE-T Half Duplex
Auto-negotiate
NOTE Your controller might not support some of the speed and duplex mode combinations. You can
see the list of speed and duplex mode combinations that are supported on your controller when you change
your network configuration. (For the procedure to change your network configuration, see “Procedure –
Configuring the Controllers.”)
Things to Know – Options for Manually Configuring the Controllers
If you will use the out-of-band method and do not have a DHCP server, you have two options for manually
configuring your controllers.
SANtricity_10.77 February 2011
LSI Corporation
- 728 -
Option 1 – Use the In-Band Management Method Initially (Recommended)
This option requires that you install the host-agent software on one of the hosts that is attached to the storage
array and then use the in-band management method to initially discover the storage array and to manually
configure the controllers.
To discover the storage array and to manually configure the controllers, perform the procedure in “Procedure
– Configuring the Controllers.”
Option 2 – Set Up a Private Network
IMPORTANT This option is recommended only if the host on which you will use the in-band
management method does not support the host-agent software.
This option requires that you install the storage management software on a management station (such as
a laptop computer) and then set up a private network to initially discover the storage array and manually
configure the controllers.
You can either connect your management station directly into Ethernet port 1 on each controller or use a hub
(Ethernet switches or routers are not permitted).
To configure the management station, perform the procedure in “Procedure – Configuring the Management
Station.”
IMPORTANT If you connect the management station directly to the Ethernet ports on the controller-
drive tray, you must use an Ethernet crossover cable. The Ethernet crossover cable is a special cable that
reverses the pin contacts between the two ends of the cable.
Procedure – Configuring the Management Station
1. Change the IP address on the TCP/IP port on the management station from an automatic assignment to
a manual assignment by using the default IP address subnet of the controllers.
Make note of the current IP address of the management station so that you can revert back to it after
you have completed the procedure.
You must set the IP address for the management station to something other than the
controller IP addresses (for example, use 192.168.128.100 for an IPv4 network, or use
FE80:0000:0000:0000:02A0:B8FF:FE29:1D7C for an IPv6 network).
NOTE In an IPv4 network, the default IP addresses for Ethernet port 1 on controller A and
controller B are 192.168.128.101 and 192.168.128.102, respectively.
If your network is an IPv4 network, check the subnet mask to verify that it is set to 255.255.255.0,
which is the default setting.
Refer to your operating system documentation for instructions about how to change the network
settings on the management station and how to verify that the address has changed.
2. After you have configured your management station, perform the procedure in “Procedure – Configuring
the Controllers.”
Procedure – Configuring the Controllers
1. In the Devices tab on the Enterprise Management Window, double-click the storage array for which you
want to configure the controller network settings.

your Ethernet switch also is set to Auto-negotiate. Connectivity issues might occur if Auto-negotiate is
not selected in SANtricity ES Storage Manager and is not set for the Ethernet switch.
6. Depending on the format of your network configuration information, select the Enable IPv4 check box,
the Enable IPv6 check box, or both check boxes.
7. Depending on the format that you have selected, enter the network configuration information (IP address,
subnet mask, and gateway or IP address and routable IP address) in the IPv4 Settings tab or the IPv6
Settings tab.
NOTE You must obtain the network configuration information from your network administrator.
8. Select Controller B, Port 1 in the Ethernet port drop-down list, and repeat step 5 through step 7 for
controller B.

Step 11 – Setting a Password
Things to Know – Passwords
You need to set a password for your storage array to protect it from serious damage, such as data loss.
When you set a password, only authorized personnel are allowed to run the commands that change the
state of the storage array, such as commands to create volumes and the commands to modify the cache
settings.
For increased protection, use a long password with at least 15 alphanumeric characters. The maximum
password length is 30 characters.
Passwords are case sensitive.
You will be asked for a password only when you first attempt to change the configuration (such as
creating a volume) or when you first perform a destructive operation (such as deleting a volume). You
must exit both the Array Management Window and the Enterprise Management Window to be asked for
the password again.
Any type of view operation does not require a password at any time.
If you no longer want to have the storage array password-protected, enter the current password, and then
leave the New password text box and the Confirm password text box blank.
NOTE The storage array is different from the pass phrase used for SafeStore Drive Security.
IMPORTANT If you forget your password, you must contact your Customer and Technical Support
representative for help to reset it.
Procedure – Setting a Password
1. From the Setup tab on the Enterprise Management Window, click Manage a Storage Array.
The Select Storage Array dialog appears.
2. Highlight the storage array for which you want to set a password, and click OK.
The associated Array Management Window is launched.
3. From the Setup tab on the Array Management Window, click Set a Storage Array Password.

Step 12 – Removing a Storage Array
Things to Know – Removing Storage Arrays
When you remove a storage array, multiple storage arrays, or a host, they are removed from the
Enterprise Management Window of your storage management station. They can be viewed from other
storage management stations.
You can delete the storage arrays and hosts from the Tree view or the Table view. These views are
located on the Devices tab on the Enterprise Management Window. However, you can delete only one
storage array at a time from the Tree view.
Procedure – Removing a Storage Array
Use these steps to remove a storage array, multiple storage arrays, or a host to which multiple storage arrays
are connected.
1. From the Tree view or the Table view in the Enterprise Management Window Devices tab, select the
storage array, the storage arrays, or the host that you want to remove.
NOTE Before you try to remove a storage array, multiple storage arrays, or a host, you must close
all of the Array Management Windows and the Script Editor dialogs that are associated with the selected
storage arrays. If the Array Management Window or the Script Editor dialog is open for a storage array,
that storage array is not removed. All of the other storage arrays are removed.
2. Select Edit >> Remove.
3. In the confirmation dialog, click Yes to remove the storage array.
NOTE While removing multiple storage arrays, multiple confirmation dialogs, one for each storage
array, appear.
Depending on what you have selected to be removed, one of these actions occurs:
If you have selected a storage array, the storage array is removed from the Enterprise Management
Window.
If you have selected multiple storage arrays, the storage arrays are removed from the Enterprise
Management Window.
If you have selected a host, the host and its associated storage arrays are removed from the
Enterprise Management Window.

Step 13 – Configuring Email Alerts and SNMP Alerts
Key Terms
Management Information Base (MIB)
CONTEXT [Management] The specification and formal description of a set of objects and variables that can
be read and possibly written using the Simple Network Management Protocol (SNMP). (The Dictionary of
Storage Networking Terminology, 2004)
Simple Network Management Protocol (SNMP)
CONTEXT [Network] [Standards] An IETF protocol for monitoring and managing systems and devices in a
network. The data being monitored and managed is defined by a Management Information Base (MIB). The
functions supported by the protocol are the request and retrieval of data, the setting or writing of data, and
traps that signal the occurrence of events. (The Dictionary of Storage Networking Terminology)
Things to Know – Alert Notifications
Setting alert destinations lets you specify addresses for the delivery of email messages and SNMP trap
messages whenever a critical problem exists with the storage array.
You must have the Event Monitor running on a machine (a management station or a host) to receive
alerts. The machine should be one that runs continuously.
IMPORTANT If you choose not to automatically enable the event monitor during installation, you do not
receive critical alert notifications.
Procedure – Setting Alert Notifications
1. From the Setup tab on the Enterprise Management Window, click Configure Alerts.
The Select Storage Array dialog appears.
2. Indicate on which storage arrays you want the alerts to be set, and click OK.
If you selected the All Storage Arrays choice, the main Alerts dialog appears.
If you selected the Individual Storage Array choice, you must first select the specific storage array
and click OK before the main Alerts dialog appears.
If you selected the Specific Host choice, you must first select a host and click OK before the main
Alerts dialog appears.
3. Specify the alerts that you want by using the tabs on the dialog. Use this information, and click OK when
you are finished setting the alerts.
Mail Server Tab
You must specify a mail server and an email sender address if you want to set email alerts. The mail
server and sender address are not required if you are setting SNMP alerts.
The Sender Contact Information is optional. Include the information if you plan to send alerts to your
Customer and Technical Support representative; otherwise, delete the fields.
Email Tab
Enter the email addresses in standard format, such as xxx@company.com.
If one of the email alerts that you configure is for your Customer and Technical Support
representative, make sure that you select the Event + Profile or Event + Support choice in the
Information to Send column. This additional information aids in troubleshooting your storage array.
The Event + Support choice includes the profile.

Step 14 – Changing the Cache Memory Settings
Key Terms
cache memory
An area of random access memory (RAM) on the controller. This memory is dedicated to collecting and
holding related data until a drive tray or a storage tray is ready to process the data. Cache memory has a
faster access time than the actual drive media.
Things to Know – Cache Memory Settings
If the data requested from the host for a read exists in the cache memory from a previous operation, the
drive is not accessed. The requested data is read from the cache memory.
Write data is written initially to the cache memory. When a percentage of unwritten data is reached, the
data is flushed from or written to the drives.
During a controller failure, the data in the cache memory of the controller might be lost.
To protect data in the cache memory, you can set a low percentage of unwritten data in the cache
memory to trigger a flush to the drives. However, as the number of drive reads and drive writes increases,
this setting decreases performance.
When cache mirroring is enabled, if one controller in a controller tray or controller-drive tray fails, the
second controller takes over. The surviving controller uses its mirrored version of the failed controller’s
cache data to continue reading from and writing to the volumes previously managed by the failed
controller.
Procedure – Viewing the Cache Memory Size Information
1. From the Setup tab on the Enterprise Management Window, click Manage a Storage Array.
The Select Storage Array dialog appears.
2. Select the storage array that you want to manage, and click OK.
The associated Array Management Window is launched.
3. Click the Physical tab.
4. Select controller A in the Physical pane of the Array Management Window, and the Properties view
appears in the left pane.
5. Scroll through the Base tab until you find the cache information and the cache backup device information.

Step 15 – Enabling the Premium Features
IMPORTANT If you did not obtain any premium feature key files from your storage vendor, skip this
step.
Key Terms
premium feature
A feature that is not available in the standard configuration of the storage management software.
Things to Know – Premium Features
You enable a premium feature through a feature key file that you obtain from your storage vendor. The
feature key file is either enabled or disabled. When a premium feature is disabled, it does not appear in the
graphical user interface (GUI).
If your system is a low-tier performance configuration and you want to upgrade to a high-tier performance
configuration, use the following procedure to obtain enhanced performance.
Procedure – Enabling the Premium Features
1. From the Setup tab on the Enterprise Management Window, click Manage a Storage Array.

Step 16 – Defining the Hosts
IMPORTANT You must know the world wide port names of each HBA host port. If you have not already
recorded them, see “Installing Host Bus Adapters” for your particular configuration (CDE2600 Controller-
Drive Tray, CDE2600-60 controller-drive tray, CDE4900 controller-drive tray, or CE7900 controller tray) for
instructions to obtain these world wide port names.
IMPORTANT If you will not use storage partitions or you do not have the SANshare Storage
Partitioning premium feature enabled on your storage array, you can skip the information about “Things to
Know – Host Groups" and “Things to Know – Storage Partitions,” and go to either “Procedure – Defining the
Hosts” or “Procedure – Defining the iSCSI Hosts.”
Things to Know – Hosts
The host adapters in the hosts that are attached to the storage array are known to the storage management
software. However, the storage management software does not know which host adapters are associated
with which hosts. Use these steps to associate each host with its specific host adapters.
Things to Know – Host Groups
A host group is a group (cluster) of two or more hosts that share access, in a storage partition, to specific
volumes on the storage array. You can create an optional logical entity in the storage management
software. You must create a host group only if you will use storage partitions.
If you must define a host group, you can define it through the Define Hosts Wizard described in
“Procedure – Defining the Hosts.”
Things to Know – Storage Partitions
A storage partition is a logical entity that consists of one or more volumes that can be accessed by
a single host or can be shared among hosts that are part of a host group. You can think of a storage
partition as a virtual storage array. That is, take the physical storage array and divide it up into multiple
virtual storage arrays that you can then restrict to be accessible only by certain hosts.
SANshare Storage Partitioning is a premium feature. This premium feature was either already enabled
on your storage array at the factory, or you must purchase a feature key file from your storage vendor to
enable it.
You do not create storage partitions in this step, but you must understand them to define your hosts.
You do not need to create storage partitions if these conditions exist (see the first image below):
You have only one attached host that accesses all of the volumes on the storage array.
You plan to have all of the attached hosts share access to all of the volumes in the storage array.
Note that all of the attached hosts must have the same operating system (homogeneous), and you
must have special software on the hosts (such as clustering software) to manage volume sharing and
accessibility.
You do need to create storage partitions if these conditions exist (see the two images that display with no
partition required below):
You want certain hosts to access only certain volumes.
You have hosts with different operating systems (heterogeneous) attached in the same storage array.
You must create a storage partition for each type of host.

Step 17 – Configuring the Storage
Key Terms
Default Group
A standard node to which all host groups, hosts, and host ports that do not have any specific mappings are
assigned. The standard node shares access to any volumes that were automatically assigned default logical
unit numbers (LUNs) by the controller firmware during volume creation.
free capacity
Unassigned space in a volume group that can be used to make a volume.
full disk encryption (FDE)
A type of drive technology that can encrypt all data being written to its disk media.
hot spare drive
A spare drive that contains no data and that acts as a standby in case a drive fails in a RAID Level 1, RAID
Level 3, RAID Level 5, or RAID Level 6 volume. The hot spare drive can replace the failed drive in the
volume.
Redundant Array of Independent Disks (RAID)
CONTEXT [Storage System] A disk array in which part of the physical storage capacity is used to store
redundant information about user data stored on the remainder of the storage capacity. The redundant
information enables regeneration of user data in the event that one of the array's member disks or the access
path to it fails.
Although it does not conform to this definition, disk striping is often referred to as RAID (RAID Level 0). (The
Dictionary of Storage Networking Terminology)
storage partition
A logical entity that is made up of one or more storage array volumes. These storage array volumes can be
accessed by a single host or can be shared with hosts that can be part of a host group.
unconfigured capacity
The available space on drives of a storage array that has not been assigned to a volume group.
volume
The logical component created for the host to access storage on the storage array. A volume is created from
the capacity available on a volume group. Although a volume might consist of more than one drive, a volume
appears as one logical component to the host.
volume group
A set of drives that is logically grouped and assigned a RAID level. Each volume group created provides the
overall capacity needed to create one or more volumes.
SANtricity_10.77 February 2011

- 744 -
Things to Know – Data Assurance
The Data Assurance (DA) premium feature checks for and corrects errors that might occur as data is
communicated between a host and a storage array. DA is implemented using the SCSI direct-access block-
device protection information model. DA creates error-checking information, such as cyclic redundancy
checks (CRCs) and appends that information to each block of data. Any errors that might occur when a block
of data is either transmitted or stored are then detected and corrected by checking the data with its error-
checking information.
Only certain configurations of hardware, including DA-capable drives, controllers, and host interface cards
(HICs), support the DA premium feature. When you install the DA premium feature on a storage array,
SANtricity ES Storage Manager provides options to use DA with certain operations. For example, you can
create a volume group that includes DA-capable drives, and then create a volume within that volume group
that is DA-enabled. Other operations that use a DA-enabled volume have options to support the DA premium
feature.
If you choose to create a DA-capable volume group, select the Create a Data Assurance (DA) capable
volume group check box. This check box is enabled only when there is at least one DA-capable drive in the
storage array and is, by default, selected if it is enabled.
When the DA premium feature is enabled, the DA Enabled column appears in the Source volume list in the
Create Copy Wizard – Introduction dialog. If you choose to copy a DA-enabled source volume to a target
volume that is not DA enabled, you are prompted to confirm your choice. The copy can be completed, but the
resulting copy is not DA enabled.
IMPORTANT If a volume group is DA-capable and contains a DA-enabled volume, use only DA-
capable drives for hot spare coverage. A volume group that is not DA capable cannot include a DA-enabled
volume.
You can verify that a drive contains DA-enabled volumes by checking that the Data Assurance (DA) capable
property is set to "yes".
Things to Know – Allocating Capacity
You can create volumes from either unconfigured capacity or free capacity on an existing volume group.
If you create a volume from unconfigured capacity, you must first specify the parameters for a new
volume group (RAID level and capacity for a set of drives) before you specify the parameters for the
first volume on the new volume group.
If you create a volume from free capacity, you have to specify the parameters of only the volume,
because the volume group already exists.
As you configure the capacity on the storage array, make sure that you leave some unassigned drives
available. You might need to use these drives for these reasons:
To create additional volume groups for new capacity requirements
For hot spare drive protection
To increase the free capacity on an existing volume group to provide for future capacity needs
For additional storage required for certain premium features, such as Snapshot Volume
If your storage array contains more than one type of drive (such as Fibre Channel or SATA), an
Unconfigured Capacity node will be associated with each drive type. You cannot mix drives of different
types within the same volume group.
SANtricity_10.77 February 2011
LSI Corporation
- 745 -
If you are adding capacity to a Data Assurance (DA) -capable volume group, use only drives that are
DA capable. If you add a drive or drives that are not DA-capable, the volume group no longer has DA
capabilities, and you no longer have the option to enable DA on newly created volumes within the volume
group. The DA Capable column in the Available drives list shows the DA capabilities of each listed drive.
If you are adding capacity to a volume group that is not DA capable, do not use drives that are DA
capable because the volume group will not be able to take advantage of the capabilities of DA-capable
drives. The DA Capable column in the Available drives list shows the DA capabilities of each listed drive.
Things to Know – Volume Groups and Volumes
You can create a single volume or multiple volumes per volume group. Usually, you will create more
than one volume per volume group to address different data needs or because of limits on the maximum
capacity of a single volume.
NOTE If you choose to copy a Data Assurance (DA) enabled source volume to a target volume that is
not DA-enabled, you are prompted to confirm your choice. The copy can be completed, but the resulting copy
is not DA-enabled. For more information about how volume copy is affected by DA-enabled volumes, refer to
Volume Copy Premium Feature electronic document topics or the PDF located on the SANtricity ES Storage
Manager Installation DVD.
While creating volume groups, you must make sure that the drives that comprise the volume group are
located in different drive trays. This method of creating volume groups is called tray loss protection. Tray
loss protection guarantees accessibility to the data on the volumes in a volume group if a total loss of
communication occurs with a single drive tray. Communication loss might occur due to loss of power to
the drive tray or failure of the drive tray ESMs.
The RAID levels supported are RAID Level 0, RAID Level 1, RAID Level 3, RAID Level 5, RAID Level 6,
and RAID Level 10 (1 + 0).
RAID Level 0 provides no data redundancy.
RAID Level 10 is not a separate RAID level choice but is supported when you create a RAID Level 1
volume group that consists of four or more drives.
You can assign RAID Level 1 only to volume groups with an even number of drives.
You can assign RAID Level 3 or RAID Level 5 only to volume groups with three or more drives.
You can assign RAID Level 6 only to volume groups with five or more drives.
NOTE RAID Level 6 is a premium feature. This premium feature was either already enabled on
your storage array at the factory, or you must purchase a feature key file from your storage vendor to
enable it.
Things to Know – Host-to-Volume Mappings and Storage Partitions
Each volume that you create must be mapped to a logical address called a logical unit number (LUN).
The host uses this address to access data on the volume.
When you create a volume manually, you have two choices for mapping:
Default mapping – Choose this option if you do not intend to use storage partitions. The storage
management software will automatically assign a LUN to the volume and make the volume available
to all of the hosts that are attached to the storage array in the Default Group (partition).
Map later (assign specific mapping) – Choose this option if you intend to use storage partitions.
Use the Define Storage Partition Wizard to indicate the host group or host, specify the volumes that
you want the host group or host to access, and access the LUNs to assign to each volume.

Things to Know – Hot Spare Drives
The hot spare drive adds a level of redundancy to your storage array. It is highly recommended that you
create hot spare drives for each type of drive in your storage array.
Hot spare drives do not provide protection for RAID Level 0 volume groups because data redundancy
does not exist on these volume groups.
A hot spare drive is not dedicated to a specific volume group but instead is global, which means that a hot
spare drive will be used for any failed drive in the storage array. The failed drive must be the same drive
type and have a capacity that is equal to or smaller than the particular hot spare drive.
Things to Know – Full Disk Encryption
SafeStore Drive Security and SafeStore Enterprise Key Manager (EKM) are premium features that prevent
unauthorized access to the data on a drive that is physically removed from the storage array. Controllers in
the storage array have a security key. Secure drives provide access to data only through a controller that
has the correct security key. The security key can be managed locally by the controllers or externally by an
external key management server, which is the EKM premium feature. Both SafeStore Drive Security and EKM
must be enabled either by you or your storage vendor.
The SafeStore Drive Security premium feature requires security-capable full disk encryption (FDE) drives.
A security-capable FDE drive encrypts data during writes and decrypts data during reads. Each security-
capable drive has a unique drive encryption key.
When you create a secure volume group from security-capable FDE drives, the drives in that volume group
become security enabled. When a security-capable FDE drive has been security enabled, the drive requires
the correct security key from a controller to read or write the data. All of the drives and controllers in a storage
array share the same security key. The shared security key provides read and write access to the drives,
while the drive encryption key on each drive is used to encrypt the data. A FDE drive works like any other
drive until it is security enabled.
Whenever the power is turned off and turned on again or is removed from the controller-drive tray, all of the
FDE drives change to a security locked state. In this state, the data is inaccessible until the correct security
key is provided by a controller.
You can view the SafeStore Drive Security status of any drive in the storage array from the Drive Properties
dialog. The status information reports whether the drive is:
Security-capable
Secure – Security enabled or disabled
Read/Write Accessible – Security locked or unlocked
You can view the security status of any volume group in the storage array from the Volume Group Properties
dialog. The status information reports whether the storage array is one of the following:
Security-capable
Secure
The following table shows how to interpret the security properties status of a volume group.

When the SafeStore Drive Security premium feature has been enabled, the Drive Security menu appears in
the Storage Array menu. The Drive Security menu has these options:
Create Security Key
Change Security Key
Save Security Key
Unlock Drives
NOTE If you have not created a security key for the storage array, only the Create Security Key option
is active.
If you have created a security key for the storage array, the Create Security Key option is inactive with a
check mark to the left. The Change Security Key option and the Save Security Key options are now active.
The Unlock Drives option is active if any security-locked drives exist in the storage array.
When the SafeStore Drive Security premium feature has been enabled, the Secure Drives option appears in
the Volume Group menu. The Secure Drives option is active if these conditions are true:
The selected storage array is not security enabled but is composed entirely of security-capable drives.
The storage array contains no snapshot base volumes or snapshot repository volumes.
The volume group is in Optimal status.
A security key is set up for the storage array.
The Secure Drives option is inactive if the previous conditions are not true.
The Secure Drives option is inactive with a check mark to the left if the volume group is already security
enabled.
You can erase security-enabled drives instantly and permanently so that you can reuse the drives in another
volume group or in another storage array. You can also erase them if the drives are being decommissioned.
When you erase security-enabled drives, the data on that drive becomes permanently inaccessible and
cannot be read. When all of the drives that you have selected in the Physical pane are security enabled, and
none of the selected drives is part of a volume group, the Secure Erase option appears in the Drive menu.

The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security premium feature and
should not be confused with the pass phrase that is used to protect copies of a SafeStore Drive Security
security key. However, it is good practice to set a storage array password before you create, change, or save
a SafeStore Drive Security security key or unlock secure drives.
Procedure – Configuring the Storage
1. From the Setup tab on the Enterprise Management Window, click Manage a Storage Array.
The Select Storage Array dialog appears.
2. Highlight the storage array on which you want to configure storage, and click OK.
The associated Array Management Window is launched.
3. From the Setup tab on the Array Management Window, click Configure Storage Array.
4. Choose the applicable configuration task:
Automatic configuration – This method creates volume groups with equal-sized capacity volumes
and also automatically assigns appropriate hot spare drive protection. Use this method if you do not
have unique capacity requirements for each volume or you want a quick method to configure volume
groups, volumes, and hot spare drives. You can choose from a list of suggested configurations, or
you can create your own custom configuration.
Create volume groups and volumes – This method creates one volume at a time but gives you
more control over the volume group and volume parameters (such as RAID level, volume group,
volume capacity, and so on). Use this method if you have unique capacity requirements for most of
the volumes that you will create and you want more control in specifying various parameters.
Configure hot spare drives – This method lets you either have the software automatically assign
applicable hot spare protection (which is identical to the automatic configuration method described
previously) or manually create a hot spare drive from an unassigned drive that you select.
5. To create the volume groups, volumes, and hot spare drives, perform one of these actions depending
on your storage partition requirements. Refer to the on-screen instructions and the online help topics for
more information.
No storage partition is required, and you selected the automatic configuration method – Go to
step 6.
No storage partition is required, and you selected the manual configuration method – Verify
whether all volumes are mapped to the Default Group, and go to step 8.
A storage partition is required – Go to step 7.
6. Perform these actions:
a. From the Setup tab on the Array Management Window, click Map Volumes.
b. Select the Default Group, and assign each volume a logical unit number (LUN).
c. Go to step 8.
NOTE To map all volumes into the Default Group, you should have selected the Default
Mapping option while creating the volumes.
7. Perform these actions:
a. Click the Mappings tab.
b. Specify the applicable host or host group, volumes, and LUNs.
c. Select Mappings >> Define, and click SANshare Storage Partitioning.
d. Refer to the on-screen instructions.
SANtricity_10.77 February 2011
LSI Corporation
- 749 -
e. Repeat step a through step d for each storage partition.
f. Go to step 8.
8. After you have created all of the volumes and mappings, use the applicable procedures on your hosts to
register the volumes and to make them available to your operating system.
Depending on your operating system, two utilities are included with the storage management
software (hot_add and SMdevices). These utilities help register the volumes with the hosts and also
show the applicable device names for the volumes.
You also will need to use specific tools and options that are provided with your operating system to
make the volumes available (that is, assign drive letters, create mount points, and so on). Refer to
your host operating system documentation for details.
If you are using the HP-UX OS, you must run this command on each host to change the I/O timeout
value to 120 seconds on each block device (volume) that you created on the storage array, where
cxtxdx is the device name of each volume.
pvchange -t 120 /dev/dsk/cxtxdx
NOTE If you reboot your host, you must run the pvchange command again.
NOTE After you configure the volume, you can change the cache memory settings of the volume.
See “Procedure – Changing the Volume Cache Memory Settings.”

Step 18 – Downloading the Drive and ATA Translator Firmware
for SATA Drives and the DE6900 Drive Tray
Each SATA drive in a DE6900 drive tray is connected to a corresponding ATA translator (12 to a drawer).
The ATA translator provides Fibre Channel (FC) protocol to Serial Advanced Technology Attachment (SATA)
protocol translation for the SATA drives in the storage array.
Use the Drive/ATA Translator Firmware option to transfer a downloadable firmware file to the drives and
the Advanced Technology Attachment (ATA) translators in the storage array only if the drives and the ATA
translators in the storage array are experiencing firmware-related limitations or performance issues. Obtain
drive and ATA translator firmware only from your storage supplier.
You can download firmware files to multiple drives and ATA translators at a time to keep downtime to a
minimum.
ATTENTION Risk of application errors – Stop all I/O activity to the storage array before downloading
the firmware to prevent application errors. Before starting any firmware download, make sure that all data on
the affected drives is backed up.
Keep these important guidelines in mind when you download firmware to avoid the risk of application errors:
Downloading firmware incorrectly could result in damage to the drives or loss of data. Perform downloads
only under the guidance of your Customer and Technical Support representative.
Stop all I/O to the storage array before the download.
Make sure that the firmware that you download to the drives and the ATA translators is compatible with
the drives and the ATA translators that you select.
Do not make any configuration changes to the storage array while downloading the firmware.
ATTENTION Possible loss of data – Perform downloads only under the guidance of your Customer
and Technical Support representative. Downloading firmware files incorrectly could result in performance
problems or loss of data.
ATTENTION Possible damage to drives and loss of data – Do not make any configuration changes
to the storage array while downloading firmware files.
IMPORTANT Before you download firmware to all of the drives, and the ATA translators in the storage
array, consider downloading to just a few drives and ATA translators to make sure that the downloads are
successful and to test the performance of the new firmware. When you are satisfied that the new firmware
works correctly, download the firmware to the remaining drives and ATA translators.

Remote Volume Mirroring Premium Feature
This topic describes how to obtain, enable, activate, and use the Remote Volume Mirroring premium feature
for SANtricity ES Storage Manager Version 10.75.

About the Remote Volume Mirroring Premium Feature
The Remote Volume Mirroring premium feature is for online, real-time replication of data between two storage
arrays in separate locations. When you create a remote volume mirror, a mirrored volume pair is created.
The mirrored volume pair is created from two standard volumes, which are logical structures that are created
on a storage array for data storage. A standard volume can be a member of only one mirrored pair. The pair
consists of a primary volume at a local storage array and a secondary volume at a remote storage array.
If a disaster occurs, or if there is a catastrophic failure in the local storage array, you can promote the
secondary volume in the remote storage array to the role of primary volume to take over responsibility for
maintaining computer operations.
Primary Volumes and Secondary Volumes
Before you can create a remote volume mirror, you must enable and activate the Remote Volume Mirroring
premium feature on both the local storage array and the remote storage array. If a volume does not exist
on either the local storage array or the remote storage array, you must create the volumes. Both the local
storage array and the remote storage array show the primary volume and the secondary volume.
When both the primary volume and the secondary volume are available, you can create a mirrored pair.
When the remote volume mirror is first created, a full synchronization automatically occurs. The data from the
primary volume is copied completely to the secondary volume.
Mirror Repository Volumes
When you activate the Remote Volume Mirroring premium feature on the storage array, two mirror repository
volumes are created in one of the volume groups on the storage array. The controller stores mirroring
information on this volume, which includes information about remote writes that are not yet complete. You can
use this information to recover from controller resets and the accidental shutting down of storage arrays.
Capacity of the mirror repository volumes –
You can create the mirror repository volumes from the unconfigured free capacity of the volume
group.
You can create a new volume group and its member mirror repository volumes from the unconfigured
free capacity of the storage array.
The default names of the mirror repository volumes are Mirror Repository 1 and Mirror Repository 2.
You cannot change these names.
The activation process creates the mirror repository volumes with equal capacity. In a dual controller
storage array, the default capacity for both mirror repository volumes is either 128 MB or 256 MB.
You can neither increase the capacity nor decrease the capacity.
Mirror RAID levels of the mirror repository volumes – When you activate the Remote Volume
Mirroring premium feature and create the volume group and mirror repository volumes from the
unconfigured free capacity of the storage array, you select the RAID level for the volume group. However,
when you create the mirror repository volumes from an existing storage array, you do not select the RAID
level.
ATTENTION Potential loss of data – Because the data stored on the mirror repository volumes is
critical, do not create mirror repository volumes in an existing volume group that has RAID level 0. If you
create a new volume group for the mirror repository volumes, do not select RAID level 0.

Using Other Premium Features with Remote Volume Mirroring
You can use the Remote Volume Mirroring premium feature with the following premium features that are
enabled and active on the primary storage array.
SANshare® Storage Partitioning – Go to Using the SANshare Storage Partitioning Premium Feature
with Remote Volume Mirroring.
Snapshot Volume – Go to Using the Snapshot Volume Premium Feature with Remote Volume Mirroring.
Volume Copy – Go to Using the Volume Copy Premium Feature with Remote Volume Mirroring.
Dynamic Volume Expansion (DVE) – Go to Using the Dynamic Volume Expansion Premium Feature
with Remote Volume Mirroring.
Using the SANshare Storage Partitioning Premium Feature with Remote
Volume Mirroring
The SANshare Storage Partitioning premium feature lets hosts share access to volumes in a storage array.
A storage partition is created when you define a collection of hosts (a host group) or a single host and then
define a volume-to-logical unit number (LUN) mapping. This mapping lets you define which host group or host
will have access to a particular volume in the storage array.
The storage partition definitions for the local storage array and the remote storage array are independent of
each other. If these definitions are put in place while the secondary volume is in a secondary role, it reduces
the administrative effort that is associated with site recovery if it becomes necessary to promote the volume to
a primary role.
Using the Snapshot Volume Premium Feature with Remote Volume Mirroring
A snapshot volume is a point-in-time image of a volume. Do not mount a snapshot volume on the same
server on which the primary volume is mounted in a remote volume mirror.
Using the Volume Copy Premium Feature with Remote Volume Mirroring
The Volume Copy premium feature copies data from a source volume to a target volume within the same
storage array.
A primary volume in a remote volume mirror can be either a source volume or a target volume in a
volume copy.
You can create a volume copy on the primary volume in a mirrored pair, but you cannot create a volume
copy on a secondary volume in a mirrored pair. You can make a copy of a secondary volume in two ways:
• Promote the secondary volume to the role of primary volume.
ATTENTION Potential loss of data access – If a role reversal is started while a volume copy
is in progress, the volume copy fails and cannot be restarted.
• Create a snapshot volume of the secondary volume, and then perform a volume copy on the
snapshot volume.
SANtricity_10.77 February 2011
LSI Corporation
- 757 -
Using the Dynamic Volume Expansion Premium Feature with Remote Volume
Mirroring
Dynamic Volume Expansion (DVE) increases the capacity of a volume. The increased capacity is achieved
by using the free capacity that is available on the volume group of the standard volume or the snapshot
repository volume.
Performing a DVE operation does not interrupt access to data on volume groups, volumes, or drives.
You can perform a DVE operation on a primary volume or a secondary volume of a mirrored pair. However,
you cannot perform a DVE operation on a mirror repository volume.
NOTE To perform a DVE operation, the remote volume mirror must be in an Optimal status. The
Properties pane in Logical view shows the status of a volume.

Switching Zoning Configurations for Remote Volume Mirroring
Because of possible restrictions at the host level, the Remote Volume Mirroring configurations contain Fibre
Channel switches. These Fibre Channel switches are zoned so that a single host adapter can access only
one controller in a storage array. Additionally, all configurations use a separate zone for the ports that are
reserved for the Remote Volume Mirroring premium feature.
IMPORTANT Do not zone the uplink port (E_port) that connects (cascades) switches within a fabric.
Switch zoning configurations are typically set up by using the switch management software that is provided
by the manufacturer of the Fibre Channel switch. This software should have been included with the materials
that were provided when the switch was purchased.
When two or more Fibre Channel switches are cascaded together, the switch management software
combines the ports for all of the switches that are linked. For example, if two 16-port Fibre Channel switches
are cascaded with a physical connection using a Fibre Channel cable, the switch management software
shows ports 0 through 31 participating in the fabric rather than two switches each with ports 0 through 15.
Therefore, a zone that is created containing any of these ports can exist on multiple cascaded switches.

Journaling File Systems and Remote Volume Mirroring
When you are using a journaling file system, you cannot gain read-only access to a remote volume. A
journaling file system does not let you mount the remote volume in Windows (NTFS); however, you can
mount the snapshot of the remote volume.

Prerequisite: Before you select the secondary volume, perform these tasks on the secondary volume
candidate:
1. Back up all data to the volume.
2. Stop all I/O activity to the volume.
3. Unmount the file system of the volume.
After you have selected the remote storage array and the primary volume, perform these steps:
1. In the Select Secondary Volume (Create Remote Volume Mirror) wizard, select the secondary volume.
IMPORTANT The secondary volume must have a capacity equal to or greater than the capacity of
the primary volume.
2. Click Next.
The Set Write Mode (Create Remote Volume Mirror) wizard appears.

Setting the Write Mode
The secondary host ports on the storage arrays are reserved for data synchronization between the primary
volume and the secondary volume in a mirrored volume pair. You can set the remote volume mirror to write
either synchronously or asynchronously.
SANtricity_10.77 February 2011
LSI Corporation
- 766 -
Synchronous mode – In the synchronous mode, the controller on the primary volume on the storage
array sends an I/O completion message back to the host storage array after the data has been
successfully copied to the secondary storage array. The synchronous mode is the preferred mode of
operation because it offers the best chance of full data recovery from the secondary storage array in the
event of a disaster; however, the data recovery can degrade the I/O performance of the host.
Asynchronous mode – In the asynchronous mode, the controller on the primary storage array sends an
I/O completion message to the host storage array before the data has been successfully copied to the
secondary storage array. The asynchronous mode offers faster host I/O performance; however, it does
not guarantee that data was successfully written to the secondary volume or that the write requests were
completed on the secondary volume in the same order they were initiated.
NOTE If you select the asynchronous mode, select whether to add the secondary volume to a write
consistency group.
Add to write consistency group option – A write consistency group makes sure that the secondary
volume receives write requests in the sequence initiated by the controller of the primary volume. You
have the option of adding the secondary volume to a write consistency group.
To set the write mode for the remote volume mirror, perform these steps:
1. In the Set Write Mode (Create Remote Volume Mirror) wizard, select either the Synchronous mode or
the Asynchronous mode.
2. Click Next.
The Select Synchronization Settings (Create Remote Volume Mirror) wizard appears.
3. Go to Setting the Synchronization Priority and the Synchronization Method.
Setting the Synchronization Priority and the Synchronization Method
You can set the priority for allocating system resources to synchronizing the remote volume mirror. When a
remote volume mirror synchronizes, system resources are allocated to the process.
Higher synchronization priorities allocate more resources to the process and might degrade I/O
performance.
Lower synchronization priorities allocate fewer resources to the process and have less impact on normal
I/O performance.
After you set the initial synchronization priority and synchronization method, you can change it. For more
information about resynchronizing volumes in a remote volume mirror, go to Resynchronizing Volumes in a
Remote Volume Mirror.
1. In the Select Synchronization Settings (Create Remote Volume Mirror) wizard, select the synchronization
priority on the Priority slide bar.
2. Select either Manual resynchronization or Automatic resynchronization.
Automatic resynchronization – Resynchronization starts immediately after communication is
restored between unsynchronized mirrored volumes.
Manual resynchronization– The mirrored pair must be manually resynchronized each time
communication is restored between unsynchronized mirrored volumes.
3. Click Next.
The Preview (Create Remote Volume Mirror) wizard appears.

Controller Ownership/Preferred Path in a Remote Volume Mirror
During a remote volume mirroring operation, the same controller must own both the primary volume and the
secondary volume. If both volumes do not have the same preferred controller when a remote volume mirror
starts, the ownership of the secondary volume is automatically transferred to the preferred controller of the
primary volume.
When the remote volume mirror is completed or is stopped, ownership of the secondary volume is
restored to its preferred controller.
If ownership of the primary volume is changed during the remote volume mirror, ownership of the
secondary volume is also changed.
If a controller fails under any of the following conditions, you must manually change controller ownership to
the alternate controller to allow the remote volume mirror to finish.
A remote volume mirror has a status of In Progress.
The preferred controller of the primary volume fails.
The ownership transfer does not occur automatically during a failover.
ATTENTION Possible loss of data – Verify that either the volumes are not in use or a multi-path
driver is installed on the host. If you change the controller ownership/preferred path while an application is
using one of the volumes, I/O activity is disrupted, and I/O errors occur unless a multi-path host is installed on
the host. If a multi-path driver is not installed on the host, or if the multi-path driver is not the RDAC multi-path
driver, you must make operating system-specific modifications to make sure that the moved volume groups
can be accessed on the new path.

Resynchronizing Volumes in a Remote Volume Mirror
There are two resynchronization methods:
Manual resynchronization – Go to Manually Resynchronizing Volumes in a Remote Volume Mirror.
Automatic resynchronization – Go to Automatically Resynchronizing Volumes in a Remote Volume
Mirror.

Resynchronizing Volumes in a Remote Volume Mirror
You might need to periodically test the communication between the primary volume and the secondary
volume in a remote volume mirror, especially after resynchronizing the volumes. For more information, go to
Testing Communication Between the Primary Volume and the Secondary Volume in a Remote Volume Mirror.
Changing the Synchronization Priority and the Synchronization Method of a
Remote Volume Mirror
The synchronization priority defines how much processing time and resources are allocated to synchronizing
the primary volume and the secondary volume of a remote volume mirror relative to system performance.
Increasing the synchronization priority of a remote volume mirror might degrade system performance. You
can set the synchronization priority for a remote volume mirror at any time. Synchronization priorities can
affect these operations:
Performing a copyback
Performing a Dynamic Volume Expansion (DVE)
Reconstructing a volume
Initializing a volume
Changing the segment size of a volume
Defragmenting a volume group
Adding free capacity to a volume group
Changing the RAID level of a volume group
To change the synchronization priority and the synchronization method after a remote volume mirror was
created, perform these steps:
1. In the Array Management Window of the storage array that contains the primary volume of the mirrored
pair, right-click the Logical tab.
2. Select Change >> Synchronization Settings.
The Change Synchronization Settings dialog appears.
3. In the Mirrored pairs table, select the primary volume and the remote volume for which to change the
synchronization priority. To select all volumes, click Select All.

4. On the Select Synchronization Priority slide bar, select the synchronization priority for the mirrored pair.
5. Select either Manual resynchronization or Automatic resynchronization.
Automatic resynchronization – Resynchronization starts immediately after communication is
restored between unsynchronized mirrored volumes.
Manual resynchronization – The mirrored pair must be manually resynchronized each time
communication is restored between unsynchronized mirrored volumes.
6. Click OK.
The Change Synchronization Settings confirmation message appears.
7. Click Yes.
The Change Synchronization Priority - Progress bar shows the progress of the resynchronization priority
change process for a remote volume mirror.
8. Click OK.
Normally Synchronized Volumes in a Remote Volume Mirror
In a normally synchronized remote volume mirror, controller owners manage the transfer of data from the
primary volume to the secondary volume. In a normal remote volume mirror, these events happen:
1. The primary volume receives a write request from a host.
2. The controller owner on the storage array logs information about the write operation to a mirror repository
volume in the storage array.
3. The controller owner writes the data to the primary volume.
4. The controller owner starts a data transfer operation to the secondary volume on the secondary storage
array.
The communication between a primary volume and a secondary volume can be either suspended or become
unsynchronized. If the communication between the primary volume and the secondary volume breaks, these
events happen:
1. The status of the mirrored pair changes to Unsynchronized.
2. A Needs Attention status appears for the storage array.
3. Data is written to the primary volume.
4. Write requests to the primary volume are logged.
5. The controller owner sends an I/O completion to the host sending the write request. Although the host
can continue to send write requests to the primary volume, no data transfer takes place to the secondary
volume. Writes to the secondary volume are suspended pending the restoration of communications
between the primary volume and the secondary volume.
When connectivity is restored between the primary volume and the secondary volume, the mirrored pair is
ready to be resynchronized.
NOTE When the primary volume and the secondary volume are resynchronized, only data that has
changed on the primary volume after the break in communication is transferred to the secondary volume.
ATTENTION Possible loss of data – If communication is broken after resynchronization starts
between the primary storage array and the secondary storage array, the new data might mix with the old data
on the secondary volume and render the data unusable in a disaster recovery situation.

Unsynchronized Volumes in a Remote Volume Mirror
The communication between a primary volume and a secondary volume can either be suspended or become
unsynchronized. If the communication between the primary volume and the secondary volume breaks, these
events occur:
1. The status of the mirrored pair changes to Unsynchronized.
2. A Needs Attention status appears for the storage array.
3. Data is written to the primary volume.
4. Write requests to the primary volume are logged.
5. The controller owner sends an I/O completion to the host sending the write request. Although the host
can continue to send write requests to the primary volume, no data transfer takes place to the secondary
volume. Writes to the secondary volume are suspended pending the restoration of communications
between the primary volume and the secondary volume.
When connectivity is restored between the primary volume and the secondary volume, the mirrored pair is
ready to be resynchronized.
NOTE When the primary volume and the secondary volume are resynchronized, only data that has
changed on the primary volume after the break in communication is transferred to the secondary volume.
ATTENTION Possible loss of data – If communication is broken after resynchronization starts
between the primary storage array and the secondary storage array, the new data might mix with the old data

volume in a remote volume mirror, especially after resynchronizing the volumes. For more information, go to
Testing Communication Between the Primary Volume and the Secondary Volume in a Remote Volume Mirror.
Automatically Resynchronizing Volumes in a Remote Volume Mirror
When automatic resynchronization is selected, the controller owner of the primary volume automatically
starts resynchronizing the data on the remote volume mirror pair immediately after communication is restored
between the primary volume and the remote volume.
ATTENTION Possible loss of data – If a resynchronization is interrupted while in progress, another
resynchronization automatically starts immediately after communication is restored between the primary
volume and the remote volume, which could destroy data integrity.
SANtricity_10.77 February 2011
LSI Corporation
- 778 -
With automatic resynchronization, you cannot add a secondary volume to a write consistency group;
therefore, write consistency during the resynchronization process is not preserved. The write order is not
consistent until the entire write consistency group achieves Optimal status. When the write consistency group
is in an Optimal state, consistency is achieved.

volume in a remote volume mirror, especially after resynchronizing the volumes. For more information, go
to Testing Communication Between the Primary Volume and the Secondary Volume in a Remote Volume
Mirror.
Manually Resynchronizing Volumes in a Remote Volume Mirror
When manual resynchronization is selected, you must manually resynchronize and resume the data transfer
on a remote volume mirror after communication is restored between the primary volume and the remote
volume. Manual resynchronization is the recommended setting for all remote volume mirrors for three
reasons:
You determine when resynchronization starts, so you can manage the process to mitigate the potential
impact on I/O performance.
In a disaster recovery situation, manual resynchronization offers the best chance of retrieving valid data.
When the secondary volume is in a write consistency group, manual resynchronization preserves the
write order.

Reversing the Roles of the Primary Volume and the Secondary
Volume in a Remote Volume Mirror
If the primary volume in a remote volume mirror fails in a disaster situation, you can reverse the roles of the
primary volume and the secondary volume to transfer the data back to the restored volume. Reversing the
roles promotes the secondary volume to the role of primary volume and demotes the primary volume to the
role of secondary volume in a remote volume mirror.
ATTENTION Potential loss of data access – If you try to reverse roles between the secondary
volume and the primary volume while a volume copy is in progress, the role reversal succeeds, but the
volume copy fails and cannot be restarted.
IMPORTANT You cannot perform a volume copy on a secondary volume in a remote volume mirror.
To create a volume copy of a secondary volume, you must reverse the roles of the secondary volume and the
primary volume, and then perform the volume copy on the new primary volume.
NOTE While a remote volume mirror is synchronizing, you cannot perform a volume copy on either the
primary volume or the secondary volume.
NOTE If you reverse roles between a secondary volume with less capacity than the primary volume
has, the role reversal succeeds, but the usable capacity of the new secondary volume (the original primary
volume) equals the total capacity of the new primary volume (the original secondary volume).

About Resumed Remote Volume Mirrors
When a remote volume mirror is suspended, data continues to read to the primary volume, but the data is
not written to the secondary volume. Writes to the primary volume are persistently logged in to the mirror
repository volumes.
After communications are restored in a remote volume mirror, data transfer between the primary volume and
the secondary volume must be resynchronized.
Automatic resynchronization – The data transfer automatically starts immediately after the volumes are
resynchronized.
Manual resynchronization – You must manually resume the remote volume mirror to restart the data
transfer. A suspended remote volume mirror stays in a Suspended status until it is manually resumed.
After the remote volume mirror resumes, data is automatically written to the secondary volume. Only the
regions of the primary volume that changed since the mirrored pair was suspended are written to the
secondary volume
ATTENTION Possible loss of data access – When you resume a remote volume mirror when either
the primary volume or the secondary volume is a member of a write consistency group, all other suspended
remote volume mirrors for mirrored pairs in the write consistency group also resume.
NOTE When the write mode is synchronous, you do not need to resynchronize the primary volume and
the secondary volume after you resume the remote volume mirror.

Volume Copy States
In a volume copy, each copy relationship maintains its state independently. The available volume copy states
follow:
Halted – The initial state of a volume copy request. No data is moving between the source volume and
the target volume. The source volume can accept I/O requests. The target volume can accept read
requests. Based on its permission levels, the target volume can either accept or reject I/O requests.
Copy-Pending – A volume copy operation was requested but has not yet started. Both the source
volume and the target volume reject I/O requests.
Copy-in-Progress – Data is being copied from the source volume to the target volume. Both the source
volume and the target volume reject I/O requests.
Copy Failed – Data copying between the source volume and the target volume has stopped. Host I/O
requests are rejected.
Complete – After the copy operation is complete, all data has been transferred from the source volume
to the target volume. Source I/O requests are available. Based on its permission levels, the target volume
can either accept or reject I/O requests.

Input/Output Performance During a Volume Copy Operation
During a volume copy operation, data is read from the source volume and written to the target volume in the
same storage array. Because the volume copy operation diverts controller processing resources from normal
I/O activity, I/O activity in the storage array can become degraded. You can use the volume copy modification
priority feature to designate how much processing time is allocated for a volume copy operation compared to
normal I/O activity. For more information, go to these topics:
System Performance Factors
Copy Modification Priority Setting
Copy Modification Priority Rate
System Performance Factors
These factors contribute to system performance:
I/O activity
Volume RAID level
Volume configuration – The number of drives in the volume group or cache parameters
Volume type – Snapshot volumes might take more time to copy than standard volumes
Copy Modification Priority Setting
The copy modification priority setting balances I/O activity with volume copy activity on a storage array. You
can select the copy modification priority while you are creating a new volume copy, or you can change it later
by using the Copy Manager.
Higher volume copy priorities allocate more resources to the volume copy operation and might degrade I/
O performance.
Lower volume copy priorities allocate fewer resources to the volume copy operation and have less impact
on normal I/O performance.
Copy Modification Priority Rate
Five copy modification priority rates are available:
Lowest
Low
Medium
High
Highest
I/O activity is prioritized, and the volume copy takes longer, when the copy modification priority is set to the
lowest priority rate. When the volume copy is prioritized, I/O activity for the storage array might be affected.

Volume Copy Restrictions
The maximum allowable number of volume copies in a storage array depends on the number of target
volumes that are available on the storage array. For more specific information about volume copy restrictions,
go to the following topics:
Read/Write Restrictions
Source Volume Restrictions
Target Volume Restrictions
Read/Write Restrictions
During a volume copy operation, the source volume rejects write requests. After a volume copy operation is
finished, the copy request can be removed.
All information about the state of the volume copy is lost.
I/O restrictions are removed.
Both the source volume and the target volume can accept read requests and write requests.
Source Volume Restrictions
You can use these types of volumes as source volumes:
A standard volume
A snapshot volume
The source volume of a snapshot volume
The primary volume in a remote volume mirror
You cannot use these types of volumes as source volumes:
The secondary volume in a remote volume mirror
A volume currently in a modification operation
A volume that is reserved by the host
You cannot use volumes in these statuses as source volumes:
A source volume or a target volume in another volume copy that is in either a Failed status, and In
Progress status, or a Pending status
A volume in a Failed status
A volume in a Degraded status
Target Volume Restrictions
You can use a volume as a target volume in only one volume copy at a time. The capacity of the target
volume must be equal to or greater than the usable capacity of the source volume. You can use these types
of volumes as target volumes:
A standard volume
The source volume of a disabled or a failed snapshot volume

Volume Copy and Data Assurance Restrictions
Volume Copy operations are allowed based on Data Assurance attributes when the Data Assurance premium
feature is enabled on the storage array. When a volume to be copied is Data Assurance protected, the target
volume also should be, but is not required to be, protected. Protection information is supplied and checked for
the source volume and the target volume in the following manner:
Both the source volume and the target volume are Data Assurance protected –
All protection information fields are verified when reading data from the source volume. The Guard
Tag field and the Reference Tag field are propagated from the source volume to the target volume.
The fields are then verified when writing data to the target volume. The application target value
provided by the source volume is verified, and then it is replaced by the value associated with the
target volume as the data is transmitted to the target volume.
IMPORTANT In this case, the I/O controller must be able to verify and replace the Application Tag on
the fly.
The source volume is Data Assurance protected, but the target volume is not Data Assurance
protected – Protection information is verified as the data is read from the source volume. Protection
information is then verified and removed as the data is written to the target volume.
The target volume is Data Assurance protected, but the source volume is not Data Assurance
protected – Data Assurance information is inserted as data is written to the target volume.

Volume Copy and Snapshot Volumes
These topics describe how Volume Copy works with snapshot volumes.
Designating a Source Volume of a Snapshot Volume as the Target Volume of a
Volume Copy
To designate the source volume of a snapshot volume as the target volume of a volume copy, you must
disable all snapshot volumes that are associated with the source volume before you can select it as a target
volume. If any snapshot volumes are associated with the target volume, the volume copy operation fails all of
the associated snapshot volumes.
Restoring Data to a Source Volume from its Associated Snapshot Volume
To restore data to a source volume from its associated snapshot volume, use Volume Copy to copy data from
the snapshot volume back to the source volume.
ATTENTION Possible loss of data access – If you are using the Windows 2000 operating system
or the Linux operating system, use Volume Copy with the Snapshot Volume premium feature to restore
snapshot volume data to the source volume. Otherwise, the source volume and the target volume can
become inaccessible to the host.
To restore the data to the source volume, perform these steps:
1. Create a volume copy of the snapshot volume, and copy the data from the snapshot volume to the target
volume of the volume copy.
2. Copy the data from the target volume back to the source volume.
NOTE Another method for producing a copy of the secondary volume is to create a snapshot volume of
the secondary volume, and then perform a volume copy operation on the snapshot volume.
SANtricity_10.77 February 2011
LSI Corporation
- 801 -
Volume Copy and Journaling File System Formatting
If the source volume was formatted with a journaling file system, the storage array might reject a read request
to the source volume, and an error message might appear. The journaling file system driver issues a write
request before it tries to issue the read request. The controller rejects the write request. This situation might
result in an error message that states that the source volume is write protected.
To prevent rejected write requests, do not try to access a source volume that is participating in a volume
copy operation while it is in an In Progress status.
To prevent an error message from appearing, make sure that the read-only permission for the target
volume is disabled after the volume copy has finished.
SANtricity_10.77 February 2011
LSI Corporation
- 802 -
Creating a Volume Copy
Before you can create a volume copy, the premium feature must be enabled on the storage array. When
you create a volume copy, make sure that the capacity of the target volume is equal to or greater than the
capacity of the source volume.
ATTENTION Potential loss of data – A volume copy overwrites all existing data on the target
volume, automatically makes the target volume read-only to the hosts, and fails all snapshot volumes that are
associated with the target volume.
Selecting the Source Volume and the Target Volume in a Volume Copy Pair
IMPORTANT A target volume must have a capacity equal to or greater than the source volume. Only
volumes that meet that criteria are candidates to be the target volume.
1. In the Array Management Window, select the Logical tab.
2. In the Logical pane, select the volume to copy.
3. On the menu bar, select Volume >> Copy >> Create.
The Introduction (Create Copy) wizard appears. The Source volume table shows the available volumes
you can select as the source volume. The volume you selected in the Logical pane is highlighted, but you
can select any volume in the list.
4. Select the source volume, and click Next.
One of these actions occurs:
When one or more volumes meet the criteria to be a target volume, the Target volume table appears.
If no volumes meet the criteria to be a target volume, the No Target Volume Candidates Found
message appears. Click OK to return to the Source volume table, and select another source volume.
5. In the Target volume table, select the target volume.
6. On the Select copy priority slide bar, select the priority for allocating system resources to the copy
operation, and click Next.
The Preview (Create Copy) wizard appears.
7. In the text box, type Yes to confirm starting the copy operation, and click Finish.
The volume copy starts, and data is read from the source volume and written to the target volume.
In the Logical pane in the Array Management Window, Operation in Progress icons appear on the
source volume and the target volume and show that the volume copy is in either a Pending status or
an In Progress status.
After the copy operation has finished, the Copy Started (Create Copy) message appears asking
whether you want to copy another source volume.
About the Controller Ownership/Preferred Path
During a volume copy, the same controller must own both the source volume and the target volume. If both
volumes do not have the same preferred controller when the volume copy starts, the ownership of the target
volume is automatically transferred to the preferred controller of the source volume.
When the volume copy is completed or is stopped, ownership of the target volume is restored to its
preferred controller.
SANtricity_10.77 February 2011
LSI Corporation
- 803 -
If ownership of the source volume is changed during the volume copy, ownership of the target volume is
also changed.
If a controller fails under any of the following conditions, you must manually change controller ownership to
the alternate controller to allow the volume copy to finish.
A volume copy has a status of In Progress.
The preferred controller of the source volume fails.
The ownership transfer does not occur automatically during a failover.
ATTENTION Possible loss of data – Verify that either the volumes are not in use or a multi-path
driver is installed on the host. If you change the controller ownership/preferred path while an application is
using one of the volumes, I/O activity is disrupted, and I/O errors occur unless a multi-path host is installed on
the host.
If a multi-path driver is not installed on the host, or if the multi-path driver is not the RDAC multi-path driver,
you must make operating system-specific modifications to make sure that the moved volume groups can be
accessed on the new path.
After a volume copy has been created, you can change its controller ownership and preferred path settings.
Go to Changing the Controller Ownership/Preferred Path for a Volume Copy.
Changing the Controller Ownership/Preferred Path for a Volume Copy

Re-Copying a Volume Copy
You can create a new volume copy from a source volume to its target volume.
A volume re-copy starts the volume copy again from the beginning.
You can use the re-copy feature to start a failed volume copy operation or a stopped volume copy
operation or to re-copy an already completed volume copy.
ATTENTION Possible loss of data – A volume re-copy operation overwrites existing data on the
target volume. If the hosts have been mapped to the source volume, the data that is copied to the target
volume when you perform the re-copy operation might have changed since the previous volume copy was
created.
To re-copy a completed volume copy, perform these steps:
1. Stop all I/O to the source volume and the target volume.
2. Unmount any file systems on the source volume and the target volume.
3. In the Array Management Window, select the Logical tab.

Changing the Target Volume Permissions for a Volume Copy
Read requests and write requests to the target volume do not take place while the volume copy is in either
a Pending status or an In Progress status, or if the volume copy fails. After the volume copy operation is
complete, the target volume automatically becomes read-only to the hosts.
To allow changes to the data on the target volume after the volume copy operation is complete, disable
the read-only permissions for the target volume.
To prevent changes to the data on the target volume after the volume copy operation is complete, enable
the read-only permissions for the target volume. You should preserve the data on the target volume under
the following circumstances:
You are using the target volume for backup purposes.
You are copying data from one storage array to a larger storage array for greater accessibility.
You are using the data on the target volume to copy back to the base volume of a disabled volume or
failed flashcopy volume.
To change target volume permissions, perform these steps:
1. In the Array Management Window, select the Logical tab.
2. On the menu bar, select Volume >>Copy >> Copy Manager.
The Copy Manager appears.
3. In the Copy Manager, select one or more copy pairs.
4. Select Change >> Target Volume Permissions.
5. Perform one of these actions:
Disable Read-Only permissions – Select Disable Read-Only. Read-write permissions are enabled
on the target volume and are automatically available to hosts after the volume copy has finished.
Make the target volume read-only to hosts – Select Read-Only. Read-only permissions are
enabled on the target volume. Write requests to the target volume are rejected even after the volume
copy has finished.

Volume Copy Troubleshooting Tips
Troubleshooting Modification Operations
If you try to create a volume copy at the same time a modification operation is running on either the source
volume or the target volume, and the volume copy is in a Pending status, an In Progress status, or a Failed
status, the volume copy cannot start.
If a modification operation is running on a source volume or a target volume after a volume copy has been
created, the modification operation must complete before the volume copy can start.
While a volume copy is in an In Progress status, no modification operation can take place on either the source
volume or the target volume.
Troubleshooting Failed Volume Copy Operations
A volume copy can fail under these conditions:
A read error from the source volume occurs.
A write error to the target volume occurs.
A failure in the storage array occurs that affects the source volume or the target volume, such as a remote
volume mirror role reversal.
When a volume copy fails, a critical event is logged in the Event Log, and a Needs Attention icon appears in
the Array Management Window.
When a volume copy is in a Needs Attention status, the host has read-only access to the source volume.
Read requests from and write requests to the target volume are rejected until the failure is corrected by
using the Recovery Guru.

System Requirements
This section describes the operating system requirements needed to install and run Support Monitor.
Memory requirements – When installing Support Monitor combined with other host software (HSW)
components, including Client, Utilities, failover driver, and Java runtime, the memory requirement with
HSW components is 1.5 GB minimum (2 GB preferred); otherwise, 1 GB minimum (1.5 GB preferred) is
sufficient.
Hard drive space requirements – When installing Support Monitor combined with other HSW
components, including Client, Utilities, failover driver, and Java runtime, the hard drive space requirement
with HSW components is 2 GB; otherwise, 1 GB minimum (1.5 GB preferred) is sufficient.
Installation duration – 15 to 20 minutes, on average.
IP address – Static IP address required for the SANtricity ES host.
SMTP IP address – SMTP IP address required for emailing support data.
My SQL database – A pre-existing MySQL database on the host must be manually uninstalled before
you can install Support Monitor with SANtricity ES.
Server system resources – Support Monitor does not limit the amount of devices an agent can monitor.
You can set up an agent to monitor as many storage arrays as you want. However, the server system
needs to provide sufficient resources for monitoring a large number of storage arrays.
SANtricity_10.77 February 2011

Software Restrictions
This section describes some of the restrictions that you might encounter while using Support Monitor.
Installation restrictions – Support Monitor installation files include the Apache Tomcat® webserver
application. Support Monitor uses Apache Tomcat to provide information to the user interface. Any other
pre-existing applications on the host that use Apache Tomcat must be uninstalled before you install the
Support Profiler.
Make sure that the Support Monitor directory structure is removed from anti-virus and backup
applications.
Any pre-existing MySQL® database on the host that was not a part of Support Monitor installation
must be uninstalled before you install Support Monitor.
Due to library incompatibility, Support Monitor cannot be installed on Red Hat 6, x64 architecture (non
Itanium).
IP address restrictions – You must install Support Monitor on a host equipped with a static IP address.
DHCP server IP addresses are not supported by Support Monitor.
File size restrictions – If you monitor a large number of storage array systems, gathering support data
takes longer, and the compressed files are larger. Support Monitor compresses the collection data file to
be between 2 MB and 5 MB.
Data gathering restrictions – Support Monitor typically takes five minutes to seven minutes to collect
data. The data collection time can be as high as 20 minutes for a storage array with more than 100 drives.
For scheduled collection, this is a background process that does not affect the performance of Support
Monitor. When performing an on-demand collection, the GUI shows that collection has been completed.
Monitoring restrictions – No mechanisms exist that prevent multiple Support Monitor instances from
trying to find data from the same storage array; therefore, monitor each storage array from only one
Support Monitor instance. Gathering data from a storage array with multiple Support Monitor instances
can cause problems. You can prevent these problems if you selectively disable the support data
collection when multiple Support Monitor instances have access to the same storage array. You can
change the frequency of data gathering or turn off data gathering for a particular storage array from
Support Monitor.
Polling mechanism restriction – The data collection process of Support Monitor is multi-threaded with a
polling mechanism in place to find the maximum number of storage arrays at pre-defined timing intervals.
Storage array restrictions – You cannot use the Support Monitor application to add a storage array.
You must use the features in SANtricity ES Storage Manager to add a storage array, or use other storage
array management methods.
Storage array definition restrictions – To avoid redundant monitoring and data collections, define the
storage arrays only within one SANtricity ES session, where Support Monitor is installed. For example,
when installing multiple client instances of SANtricity ES, select one of the following options:
Choose to install Support Monitor on only one of the SANtricity ES clients.
Do not define the same set of storage arrays within multiple SANtricity ES sessions, if all of those
SANtricity ES sessions do have Support Monitor installed.
Storage array management restrictions – In-band management is not supported.
Uninstalling restrictions – When a profiler agent is uninstalled, all of the storage arrays that were
discovered via the agent still are present within the Support Monitor GUI under Monitored Array List. Prior
to uninstalling Support Monitor agent, you must manually remove the storage arrays from the SANtricity
Enterprise Management Window (EMW) instance on the Support Monitor agent host so that Support
Monitor no longer keeps the storage arrays under Monitored array list.

Installing, Upgrading, and Uninstalling Support Monitor
This chapter describes how to install, upgrade, and uninstall Support Monitor. As previously described in
first table in Chapter 1, two types of installations exist, depending on your operating system. Some operating
systems support the Profiler Server installer, which automatically installs Support Monitor as it installs
SANtricity ES Storage Manager. Some operating systems support the Profiler Agent installer, which installs
SANtricity ES Storage Manager on the host without Profiler Server. This chapter describes both types of
installations.
Installing Support Monitor or Upgrading from a Previous Version of Support
Monitor
Installing Support Monitor replaces any previous versions of Support Monitor that you might have on your
system, if the Support Monitor major program versions are different (for example, from version 4.8 to 4.9).
The installation process for the storage management software automatically installs Support Monitor when
the installation type is either Typical or Management Station. The Custom installation offers the choice of
whether to install Support Monitor. Support Monitor is not available under the Host Installation option. To
correctly install Support Monitor, depending on your operating system, go to either "Installing Profiler Server
with SANtricity ES" on page 2-2 or "Installing Profiler Agent" on page 2-3.
Installing Profiler Server with SANtricity ES
These procedures are for installing or upgrading Support Monitor with the combined SANtricity ES Storage
Manager. When you select the installation type of either Typical or Management Station, this installation
automatically installs Support Monitor.
1. If you have a previous version of Support Monitor that was not installed as part of a SANtricity ES bundle,
installed, perform the steps in “Uninstalling the Support Monitor” on page 2-4 to completely remove that
version of the Support Monitor.
NOTE You must manually remove any MySQL database that was not part of a previous Support
Monitor installation.
2. For the Windows operating system, double-click the installation executable icon, and follow the wizard
installation steps provided on the screen.
NOTE When you install Support Monitor with SANtricity ES Storage Manager, you are not able to
specify an installation directory. The installation defaults to the SANtricity ES Storage Manager directory
structure.
After the installation completes, an icon appears on the desktop. To start Support Monitor, double-click
the icon to start a browser-based application that is independent of SANtricity ES Storage Manager.
3. For all UNIX operating systems, perform the following steps.
a. Login as root.
b. Assign execution permissions to the installation library.
# chmod +x SMIA-<OSTYPE>-<XX.XX.XX.XX>.bin
In this command, <OSTYPE> is the operating system name and <XX.XX.XX.XX> is the version
number.
c. Run the SANtricity ES Storage Manager installation script. Follow the directions provided on the
screen. Retain the UNIX installation files because they are also used to uninstall the software. You
can delete the original archive file.
SANtricity_10.77 February 2011
LSI Corporation
- 824 -
# ./SMIA-<OSTYPE>-<XX.XX.XX.XX>.bin
In this command, <OSTYPE> is the operating system name and <XX.XX.XX.XX> is the version
number.
To start Support Monitor, open a browser window and enter the URL for Support Monitor. The URL for the
Support Monitor is http://localhost:9000/. You also can access Support Monitor remotely.
Support Monitor generates a log after installation. Refer to the log for information about the installation
outcome and any error codes that might have occurred. The installation log for Windows is located at
/Program Files/StorageManager/Profiler_install.log. The installation log for UNIX is
located at /opt/StorageManager/Profiler_install.log.
Installing Profiler Agent
This installation process is for installing Profiler Agent, without Profiler Server. The Agent is needed only
when monitoring a storage array from a version of SANtricity ES that does not have a Server version. The
Agent reports information back to an instance of Support Monitor that is running on a supported Server with
SANtricity ES. In many cases, this instance of SANtricity ES can be used to monitor the storage array.
Before you install Profiler Agent, you must install SANtricity ES. During this installation, keep the following
points in mind:
Support Monitor must be installed first within the environment on a supported operating system platform.
For the operating system platform where Support Monitor is not supported, install only the SANtricity
ES client (by selecting Custom install and choosing to opt-out Support Monitor during the component
selection sequence of the installation). This option ensures that only SANtricity ES, without Support
Monitor, is installed on the host.
Install Profiler Agent, available as a stand-alone installer, under the SANtricity ES directory location on the
host (referenced in the previous bullet item) when prompted during the Profiler Agent installation.
During the Profiler Agent installation, you must provide the remote support monitor’s (profiler server) IP
address so that Profiler Agent can self register to the remote Profiler Server to complete agent-server
self-discovery.
After Profiler Agent self registers to the remote Profiler Server, all storage arrays managed by Profiler
Agent’s local SANtricity ES Enterprise Management Window will be discovered and added to the storage
array list under remote Profiler Server’s support monitor.
Uninstalling the Support Monitor
These instructions show you how to remove the combined SANtricity ES Storage Manager and Support
Monitor.
IMPORTANT Prior to uninstalling the Support Monitor agent, you must manually remove the storage
arrays from the SANtricity ES Enterprise Management Window instance on the Support Monitor agent host so
that Support Monitor no longer keeps the storage arrays under Monitored storage array list.
1. For the Windows operating system, select Add/Remove Programs in the Control Panel to remove
SANtricity ES Storage Manager. This procedure removes both SANtricity ES Storage Manager and
Support Monitor. The uninstallation procedure might leave files that were created by SANtricity ES
Storage Manager and Support Monitor after the installation was complete. These files might include trace
files, repository files, and other administrative files. Manually delete these files to completely remove
SANtricity ES Storage Manager and Support Monitor.
SANtricity_10.77 February 2011
LSI Corporation
- 825 -
2. For the UNIX operating system, go to the /opt/StorageManager/Uninstall SANtricity ES/
directory that contains the uninstall binary. Run the uninstall script using the # ./Uninstall_SANtricity_ES
command. This procedure removes both SANtricity ES Storage Manager and Support Monitor. The
uninstallation process might leave files that were not part of the original installation. Manually delete these
files to completely remove SANtricity ES Storage Manager and Support Monitor.
NOTE The UNIX uninstallation procedure uses the .bin file. The .bin files must be saved on the
host so that the combined SANtricity ES Storage Manager and Support Monitor uninstallation can occur.
The .bin files are approximately 150 MB in size.

Describing Support Monitor
This chapter describes the following tasks:
Registering Support Monitor
Rescanning devices
Collecting and saving support data
Emailing support information to pre-defined email addresses
The Support Monitor screen lists all of the devices discovered by Support Monitor. This screen contains other
necessary information for each storage array, such as the storage array name, the host that is managing the
storage array, the collection status, the last collection time, the next collection time, and the emailing and
scheduling actions. For information about the features of Support Monitor, refer to the online help topics in
Support Monitor.
Registering Support Monitor
Registration information includes the name, address, and telephone number of the customer company.
Registration information also includes the name, telephone number, and email address of the contact and the
partner company.
The registration sequence stores the customer contact information within the Support Monitor database.
You can modify the contact information stored in the Support Monitor database through the Support Monitor
application. For detailed information about registering Support Monitor, refer to the online help topics in
Support Monitor.
Rescanning Devices
The Rescan Devices feature is available for re-discovering the configuration. Both the automated polling
option and the manual rescan option extract the change in configuration information from the .bin file. Click
Rescan Devices to update the configuration information. For more information about the Rescan Devices
option, refer to the online help topics of Support Monitor.
Collecting and Saving Support Data
Support Monitor lets you collect and save support data from your storage arrays. Collected information
includes data, such as the collection time, the collection frequency, the disabled collections, the starting day
for collection, and the file-naming conventions. Scheduled (also referred to as Periodic) and on-demand data
collection includes information such as the following types of data:
Support data collection
SOC file
RLS file
Configuration file
Profiler Server maintains five scheduled data collection sets. The newest scheduled data collection set
overrides the oldest data sets. The sixth data collection set is collected manually with a different filename.
Only the latest on-demand data collection set is preserved so be certain that the last on-demand data
collection is not needed before you initiate a new on-demand collection.
SANtricity_10.77 February 2011
LSI Corporation
- 827 -
For more information about how to perform support data or SOC and RLS change log collections, refer to the
online help in Support Monitor.
Support Data File-Naming Conventions
Support data file names are different, depending on whether the data is being collected on-demand or as a
scheduled data collection. On-demand data collection does not override scheduled data collection.
All of the collected support files are compressed in a file named arrayname_timestamp.zip. The zip file
name also contains a _p or _d. For example, arrayname_ptimestamp.zip for a periodic (scheduled) data
capture or arrayname_dtimestamp.zip for an on-demand data capture.
SOC and RLS File-Naming Conventions
SOC and RLS change log files share the same file-naming convention.
The files are compressed in a file named arrayname_Change_timestamp.zip. The zip file name also
contains a _p or _d. For example, arrayname_Change_ptimestamp.zip for periodic (scheduled) data
capture or arrayname_Change_dtimestamp.zip for an on-demand data capture.
Emailing Support Information
You can send collected support data and the SOC/RLS change log files to a designated email address list.
You can edit the email address and some of the other fields from one of the following screens.
On the Send Support Data screen, you can do the following:
Edit the email address in the Send to: field. If you change this email address, this change is not
persistent. The next time you open the Send Support Data screen, the pre-defined support email address
appears.
Add additional email addresses to the CC: field, but the email containing the support data and SOC/RLS
change log files still goes to the email address shown in the Send to: field.
Send the SOC/RLS change log files to a pre-defined email address by selecting the Send change log
files to a repository address check box. You cannot edit the repository email address field. Only change
log files can be sent to the repository email address. You can add additional email addresses to the CC:
field.
Edit the Subject: field, if you prefer a subject different than the initial default subject, which is <Storage
Array> Support Data. If you change this field, the text you enter is retained and does not return to the
initial default subject.
On the Schedule Support Data Collection screen, you can do the following:
Edit the email address in the Send to: field. The Email the scheduled collection data files to a
repository address check box is selected by default. You can change the Send to: field by unselecting
the check box, then entering a new email address in the Send to: field. This new email address is
retained until you change it again.
For information about emailing support data and SOC/RLS change log files, refer to the online help topics in

Issue Resolution
What are the performance impacts on storage
for scheduled data gathering? For a medium configuration, defined as
four to five drive trays connected to either a
CE6998 controller or a CE7900 controller, the
collection overhead is about 15 to 20 minutes
when the storage array is in an Optimal state.
Because the Support Monitor collection
process uses out-of-band management, there
are no performance impacts on the I/O path
started by the profiler.
Can I configure the data that is being
collected? No. The type of commands used for data
collection are hard-coded within the Support
Monitor application, and you cannot change
or configure the data that is being collected.
Does the standard "collect all support
data" function in SANtricity ES behave any
differently when Support Monitor is installed?
No. Support Monitor does not affect existing
SANtricity ES features.
Can I send support data to an email address
other than the pre-defined location? Yes. You can change the Send to: field on
the Send Support Data screen, and you can
add additional email addresses in the CC:
field, if needed. Also, you can change the
body and subject line of the support email.
Can I modify the schedule for data collection? Yes. Click the Calendar icon to schedule the
data collection frequencies or the time for
each storage array that you are monitoring.
How can I tell whether the support capture
was successful in Support Monitor? When you are unable to collect support data
with either a scheduled data collection or an
on#demand collection process, an icon next
to the storage array shows the support data
collection status. A successful data collection
shows a green icon. A failed data collection
shows a red icon.
How can I determine what data might have
failed during the data collection procedure? View the collection log to debug the failed
collection. Also, the collection status icon
on the Support Monitor shows a "red-
failed" status when collection failures are
encountered.
Log files are found at <drive>\LSI
Corporation\Profiler Server
\webapps\ROOT\logs.
Do I get notified when a failure occurs? No explicit notification is provided when data
collection fails. However, the collection status
icon changes to a "red-failed" status.

Issue Resolution
How can I configure Support Monitor so
that only one instance is performing data
collection out of many SANtricity ES Storage
Manager instances?
Install only instance of the server on one
of the SANtricity ES Storage Manager
instances. All of the other SANtricity ES
Storage Manager instances only require the
agent.
How can I configure Support Monitor so that
no more than one storage array is performing
scheduled data collection at any one time?
In Support Monitor, view the next data
collection time, and adjust the schedules so
that no two storage arrays have the same
next data collection time.
What is the optimum frequency for scheduled
support data collection? To avoid latency in completing the scheduled
collection task, schedule the support data
collection so that a collection is not tried from
multiple storage arrays at the same time.
What can I do if a scheduled data collection
fails? If a scheduled data collection fails, Support
Monitor retries the data collection a single
time. If the retry fails, the data collection
falls back to the normal schedule. Verify
the support log. Address the problem
being reported and start a manual data
collection. If the manual collection fails,
contact a Customer and Technical Support
representative to assist in resolving the
problem.
What can I do if an on-demand collection
fails? Verify the support log. Address the problem
reported, and start a new data collection.
What can I do if no support bundles are
available for emailing? Start a manual data collection or schedule
a collection by the most recent time and try
again.
What can I do if the support data email was
never delivered to the recipient? Support Monitor can only send an email to a
pre#defined, user-configured email address.
Make sure that the values for the email server
and the email address are correct in the
Server Setup page and try again.
Support Monitor will not be able to detect
email delivery failures due to:
Blocked emails at the recipient’s email
server
The recipient’s inbox is full
An email attachment-size limit is imposed
by the recipient’s email server
Support Monitor will be able to detect
configuration errors due to:
Incorrect email server (SMTP) name/IP
address within the server configuration

Issue Resolution
Incorrect forwarding email address
Support Monitor will be able to detect
incorrect recipient’s email addresses
associated with:
The recipient’s email address: user name
portion
The recipient’s email address: domain
name portion
The logs associated with email-related errors
are in webserver.log at the following location:
\..\ProfilerServer\webapps\ROOT
\logs.
Storage Array Management
Does Support Monitor provide any analysis to
what might be wrong with the storage array? Yes. you can select two available files to
compute a SOC change log file, which can
help with an analysis of channel failures. See
the Compute Change Log Files screen in
Support Monitor.
How can I tell when a storage array is
removed in Support Monitor? When a storage array that was previously
managed by Support Monitor is removed from
SANtricity ES Storage Manager, the storage
array is relocated to the Unmanaged Arrays
area, which is visible only if there are any
unmanaged storage arrays. However, you still
can access previously collected support data
for that storage array for emailing purposes.
Why do some storage arrays appear in the
Unmonitored Storage Array table? Storage arrays appear in the Unmonitored
Storage Array table for different reasons.
For example, because the storage array was
removed from SANtricity ES Storage Manager
or because the storage array does not meet
the minimum controller firmware requirements
to be managed by Support Monitor.
What happens when I remove a storage array
from Support Monitor? If you use the Remove icon, support data is
not deleted from the host or SANtricity ES
Storage Manager. The support data is deleted
only from the Support Monitor view. The
previously collected support data files from
the removed storage arrays are still available
via file/folder access.
What can I do if no storage arrays are found
by Support Monitor? Be sure that the storage array is being
monitored by SANtricity ES and that the
Collection Agent is running. Verify the status

of the storage array. Restart Support Monitor
services, and initiate manual discovery of the
storage arrays.
How can I see if the storage array discovery
process was successful? View the Support Monitor module log file for
the corresponding agent by selecting the
agent from the list and clicking the View Log
File button. Make sure that the storage array
is being monitored by SANtricity ES Storage
Manager.

Volume Group Relocation
This document describes these four scenarios for volume group relocation:
How to move drives to a new storage array for additional capacity (data is not preserved)
How to export and import a volume group for security (data is preserved)
How to move a volume group to a different storage array (data is preserved)
How to move a drive tray to a different storage array (data is preserved)

Understanding Concepts, Restrictions, and Requirements of
Volume Group Relocation
The topics in this section provide information you need to plan and prepare for volume group relocation.
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when handling tray components.
Volume Group Relocation
ATTENTION Possible loss of data – If you physically move a storage array or storage array
components, you can cause data loss. This loss includes controllers that are not part of a volume group,
controller trays that are not part of a volume group, and controller-drive trays or drive trays after they have
been installed and configured as part of a volume group.
Use volume group relocation to move drives and drive trays within the same storage array or move them
to different storage arrays. The following features of SANtricity ES Storage Manager support volume copy
relocation.
A single, updated configuration database takes advantage of the 512-MB existing DACstore (which
provides the foundation needed for logical unit numbers [LUNs] that are larger than 2 TB), RAID Level 6,
increased partitions, and drives larger than 2 TB. Additionally, the single, updated configuration database
provides a way to manage migration scenarios.
Exported state, Contingent state, and Forced state are used for various conditions when migrating a
volume group from the source storage array to the destination storage array. The Export Volume Group
Wizard is used before migrating the volume group from the source storage array. The Import Volume
Group Wizard is used after migrating volume groups to the destination storage array. For information, see
the topics under “Exporting and Importing a Volume Group.”
A warning message appears when migrating configured volume groups if the number of volumes being added
overruns the maximum number of volumes allowed.
Upgrade and Downgrade Restrictions for RAIDCore 1 and RAIDCore 2
RAIDCore 1 does not have an export feature. Therefore, you can remove the drives or place them offline and
then remove them from the source storage array. When placing the drives in the destination storage array
that supports RAIDCore 2, the drives will appear in the Exported state or the Contingent state. Additionally,
the drives will be unusable and will remain in the Exported state or Contingent state until they are imported
using the import function.
RAIDCore 2-to-RAIDCore 1 migration is not supported. RAIDCore 1 does not know about RAIDCore 2, and
the metadata on the RAIDCore 2 drives has a DACstore number that has a later version so that the drives
show up as Unassigned or Failed in RAIDCore 1.
Software Restrictions and Firmware Restrictions
This section describes the supported software versions and firmware versions. This section also describes
restrictions that apply to specific versions of the storage management software.
SANtricity_10.77 February 2011
LSI Corporation
- 839 -
Firmware Requirements for Source Storage Arrays and Destination Storage Arrays
You can manage the source storage array in a volume group relocation procedure with the latest
maintenance version of the firmware.
The procedures in these topics were written assuming that the destination storage array is managed with
SANtricity ES Storage Manager 10.75 with firmware version 7.75 or later. If the destination storage array is
managed with a previous version of the firmware, refer to the Volume Group Relocation Customer Support
Guide for the previous version.
Persistent Reservations Are Not Preserved in Volumes or Volume Groups (Storage
Management Software Version 8.4x and Later)
When you move a volume or a volume group that was configured with a persistent reservation, the
reservation information and the registration information are not preserved.
Any reservation information or registration information that exists on a volume or a volume group is
automatically deleted when the destination storage array is relocated. For information about persistent
reservations, refer to the online help topics in the Array Management Window.
Support for 256 Volumes Per Partition (Storage Management Software Version 8.4x and Later)
IMPORTANT Possible loss of data access – If you try to map a volume to a logical unit number
(LUN) that exceeds the restriction on these operating systems, the host is unable to access the volume.
Many hosts are able to have 256 LUNs mapped per storage partition, but the number varies with the type
of operating system. Consider if you move a volume or a volume group from a storage array that supports
256 volumes per storage partition to a storage array that does not support 256 volumes. In this case, the
host cannot access any volumes that have been mapped to LUNs greater than what the operating system
supports. For information about the number of LUNs that are supported by each operating system, refer to the
online help topics.
The volume groups or the volumes that are associated with the LUN mappings remain intact. However, the
volume groups or the volumes are not available.
To recover from this situation, perform one of these actions:
If a volume is no longer needed, delete the volume.
If a LUN is available in the range that the operating system supports, remap the volume to a supported
LUN.
Map the volume to a different storage partition by using a LUN that the operating system supports.
General Restrictions of Volume Group Relocation
Several general restrictions apply that are not based on the controller firmware level or the version of
SANtricity ES Storage Manager.
Moving Drive Trays from Multiple Storage Arrays into a Single Storage Array
If you move drive trays from multiple, different storage arrays into a single destination storage array, you must
move all of the drive trays from the same storage array as a group into the new destination storage array.
SANtricity_10.77 February 2011
LSI Corporation
- 840 -
Make sure that all of the drive trays for a single group have been moved to the destination storage array
before you move the next group of drive trays.
If the drive trays are not moved as a group to the destination storage array, the newly relocated volume
groups might not appear in the Array Management Window.
Moving Drives to a Storage Array with No Current Drive Trays
If you import multiple drives or an entire drive tray into a destination storage array that does not have
any drive trays, you must make sure that the power to the controller tray or the controller-drive tray in the
destination storage array has been turned off before you attempt the relocation.
After you turn on the power to the destination storage array and it successfully recognizes the newly relocated
drives or drive trays, you can add more drives or drive trays without turning off the power to all of the drive
trays.
If you move an entire drive tray that has the DC power option, keep in mind that there are special
requirements for disconnecting and reconnecting DC power to the drive tray.
WARNING (W14) Risk of bodily injury – A qualified service person is required to make the DC
power connection according to NEC and CEC guidelines.
Hitachi Drives Installed in a Just a Bunch of Disks (JBOD) Drive Tray Reports Drives as
Missing
If you change tray IDs on Hitachi drives that are installed into a JBOD drive tray, you must restart the system.
If you do not restart the system, the tray IDs are not added to the loop, and the system reports the drives as
missing or absent.
Missing Volumes and Offline Volumes Appear After Volume Group Relocation
If you move volume groups or volumes from one storage array to another, the volumes appear to be absent
or can unexpectedly appear Offline.
To prevent this situation, make sure that all of the volumes that you move are taken offline before you try to
physically relocate them to the destination storage array.
Excessive Volume Group Relocation
IMPORTANT Do not relocate volume groups and volumes in an excessive manner into the same
storage array.
Excessive volume group relocation can be defined as follows: when the total number of volumes on the
destination storage array plus the number of volumes that are relocated to the destination storage array
exceed the total number of volumes that can be managed by the controllers in the destination storage array.
When excessive volume group relocation occurs, these conditions occur on the destination storage array:
All pre-existing standard RAID volumes on the destination storage array are kept.
All standard RAID volumes relocated to the destination storage array are kept.
If hot volume group relocation occurs, access to pre-existing volumes on the destination storage array is
maintained.
SANtricity_10.77 February 2011
LSI Corporation
- 841 -
If excessive volume group relocation occurs, the volume groups or the volumes that moved to the destination
storage array do not appear in the Array Management Window. In addition, they are not shown by the host,
even though the definitions are kept in the configuration. Critical Major Event Log (MEL) events are not
generated. The Array Management Window does not show that an excess volume group relocation has
occurred.
If pre-existing volumes on the destination storage array are deleted, the excess volumes might become visible
in the Array Management Window, and the excess volumes also become visible to the host. Usually, the
status of the excess volumes after they become visible is the same status they had before you moved the
excess volumes to the destination storage array. These excess volumes might show a Failed status. You can
recover them if you manually put the volume group online in the Array Management Window.
Maximum Number of Drives in a Storage Array
When you relocate drives, volume groups, or drive trays to a destination storage array, make sure that the
new configuration does not exceed the maximum number of drives that are supported by the controllers in the
destination storage array.
ATTENTION Possible data loss or corruption – If you exceed the number of drives by importing
more drives than the storage array supports, data loss or data corruption can occur.
Volumes Might Become Unstable After Drives Have Been Relocated
Volume groups or volumes that are moved from one storage array to the destination storage array can have
timing issues.
When you insert drives into the destination storage array, wait at least two minutes before you insert each
drive. If you do not wait two minutes, the storage array can become unstable.
Solid State Disk (SSD) Drives
The option to use Solid State Disk (SSD) drives in place of conventional drives is available as a premium
feature with some hardware. The FC4600 drive tray and the DE1600 drive tray can have SSD drives. If you
relocate a volume group that includes SSD drives, the destination hardware must support those drives.
Drive Firmware Restrictions
Relocation of drives from a drive tray with a 1-Gb/s data transfer rate to a drive tray with a 2-Gb/s data
transfer rate is restricted to drives with specific drive firmware levels.
ATTENTION Possible data loss or corruption – Perform a hot volume group relocation whenever
possible. This action makes sure that any volume groups or volumes that you move to different destination
storage arrays are correctly recognized and managed by the new storage array.
For information about the drive firmware, refer to the Compatibility Matrix, which is available in the LSI
Knowledge Database.
Premium Feature Restrictions
Premium features are not in the standard configuration of storage management software. Premium features
require a feature key file to enable each specific premium feature. Before you can move volume groups or
volumes, you must first enable the required premium features on the destination storage array.
SANtricity_10.77 February 2011
LSI Corporation
- 842 -
After you move a volume or a volume group that uses premium features to the destination storage array, an
Out of Compliance error message might appear. For procedures to correct the error, refer to the Recovery
Guru.
The following table lists the premium features that are available for all current releases of the storage
management software.
NOTE Support for 256 volumes per partition is not considered a premium feature because this support
was introduced as a supported feature in Version 8.40 of the storage management software.

Snapshot Volumes (Storage Management Software Version 8.x and Later)
IMPORTANT If you have created a snapshot volume of a base volume, in some cases, the base
volume and the snapshot repository volume can reside in different volume groups. If you want to keep the
data in the snapshot volume, you must locate and move all of the volume groups that contain snapshot
repository volumes that are associated with the snapshot volume. If you do not move all of the associated
volumes, the snapshot volume becomes unusable in both the source storage array and the destination
storage array.
When you create a snapshot volume, you can allocate capacity for the associated snapshot repository
volume in the same volume group as the base volume. You can also use free capacity on a different volume
group.
Situations can occur where not all of the associated components of the snapshot volume are moved to the
destination storage array, which result in failed volumes or absent volumes. Problems with volume ownership
might also occur while you relocate snapshot volume components that are located in different volume groups.
These sections describe the conditions that result when you move volume groups that contain some or all of
the snapshot volume components.
SANtricity_10.77 February 2011

- 843 -
Moving All of the Snapshot Volume Components
If you move a volume group that contains all of the snapshot volume information (base volume, snapshot
volume, and snapshot repository volume) from the source storage array to a destination storage array,
various conditions can occur.
NOTE These conditions also occur when multiple volume groups that contain all of the snapshot
volume components are moved at one time.
These conditions occur on the source storage array:
The controller firmware keeps full knowledge of the snapshot volume in the source storage array.
The base volume and the snapshot repository volumes appear as missing volumes or absent volumes.
Write requests to the snapshot volume cause the snapshot volume to fail.
Read requests to the snapshot volume can cause the snapshot volume to fail or can cause the host I/O
request to fail.
If you reinstall the physical drives into the original drive tray, the affected base volume, snapshot volume,
and snapshot repository volumes return to the state they were in before the drives were removed.
These conditions occur on the destination storage array:
The controller firmware puts full knowledge of the snapshot volume onto the destination storage array.
The snapshot volume is set to the same status as it was on the source storage array.
Moving a Base Volume and a Snapshot Volume without the Associated Snapshot Repository
Volume
If you move a volume group that contains a base volume and snapshot volume from the source storage array
to the destination storage array, various conditions occur.
NOTE In this case, the associated snapshot repository volume stays on the source storage array.
These conditions occur on the source storage array:
The controller firmware keeps full knowledge of the snapshot volume in the source storage array.
The base volume appears as an absent volume.
Host I/O requests to the base volume fail.
Write requests to the snapshot volume can cause the snapshot volume to fail.
Read requests to the snapshot volume can succeed or can cause the host I/O to fail.
These conditions occur on the destination storage array:
The controller firmware puts full knowledge of the snapshot volume on to the destination storage array.
The snapshot repository volume appears as an absent volume.
Write requests to the snapshot volume can cause the snapshot volume to fail.
Read requests to the snapshot volume can fail the snapshot volume.
If the snapshot repository volume is added to the system later, the snapshot volume stays failed.

Moving a Snapshot Repository Volume without the Base Volume and the Snapshot Volume
If you move a volume group that contains a snapshot repository volume from the source storage array to a
destination storage array, various conditions occur.
NOTE In this case, the associated base volume and the snapshot volumes stay on the source storage
array.
These conditions occur on the source storage array:
The controller firmware keeps full knowledge of the snapshot volume in the source storage array.
The snapshot repository volume appears as an absent volume.
Host I/O to the base volume is permitted, but writes to the base volume cause the snapshot volume to fail.
Read requests to the snapshot volume can fail the snapshot volume or can cause the host I/O to fail.
If the physical drives are replaced into the original drive tray and the snapshot volume remains in an
Optimal status, the affected volumes are brought back to the state they were in before the snapshot
repository volume was moved. The affected volumes include the base volume, the snapshot volume, and
the snapshot repository volume. The snapshot volume becomes fully operational.
These conditions occur on the destination storage array:
The controller firmware puts full knowledge of the snapshot volume onto the destination storage array.
The base volume and the snapshot volume appear as absent volumes.
Host I/O requests to the base volume fail in the destination storage array because the base volume is not
present.
Write requests to the snapshot volume can cause the snapshot volume to fail.
Read requests to the snapshot volume can succeed or can cause the host I/O to fail.
Controller Ownership Changes During Relocation
During the volume group relocation process, you must make sure that controller ownership remains the same
for all of the volume groups that contain associated snapshot volume components.
When volume groups are relocated to a different storage array, controller ownership is assigned to controller
A by default. If a change in controller ownership occurs on the destination storage array before all of the
snapshot volume components are relocated, a dual-controller ownership situation might occur. The situation
where neither controller A nor controller B has ownership can also occur.
A change in controller ownership can result from a forced failover or can be the result of a manual change.
For example, a volume group that contains the base volume and the snapshot volume is moved to the
destination storage array. The volume group is owned by controller A by default. A forced failover occurs on
the destination storage array, which changes the controller ownership of the volume group to controller B.
When the volume group that contains the associated snapshot repository volume is moved to the destination
storage array, it is owned by controller A by default. This process results in a dual-ownership situation. Both
controller A and controller B attempt to assume ownership of all of the snapshot volume components.
To prevent dual-controller ownership or no-controller ownership situations, make sure that the second volume
group is not moved to the destination storage array until the controller ownership of the first volume group is
changed back to controller A.

After both volume groups are moved, you can change the controller ownership to controller B for all volume
groups.
Remote Volume Mirroring (Storage Management Software Version 8.20 and Later)
Before you relocate volumes that participate in a mirror relationship, you must remove the mirror relationship
between the primary volume and the secondary volume. This action prevents orphan mirrors on the remote
storage array. For instructions about how to remove mirror relationships, refer to the topics under SANtricity
ES Storage Manager Remote Volume Mirroring , the corresponding PDF document on the SANtricity ES
Storage Manager Installation DVD, or the online help topics in the Array Management Window.
If drives that contain mirror repository volumes are moved from a source storage array that is managed by
SANtricity Storage Manager 8.20 or later to a destination storage array that is managed by SANtricity Storage
Manager 8.00, the mirror repository volumes are not deleted. You must return the drives to the source storage
array and deactivate the Remote Volume Mirroring premium feature before you attempt the relocation.
When you move mirror repository volumes from the source storage array to a destination storage array, the
mirror repository volume is automatically deleted and cannot be returned to the source storage array.
If the absent volume in the source storage array is deleted and the volume group is reinstalled in the source
storage array, the primary volume or the secondary volume appears as a standard volume with no mirroring
properties.
Volume Copy (Storage Management Software Version 8.4x and Later)
Before you relocate volume groups that contain volume copies from the source storage array to a destination
storage array, make sure that any copy pairs associated with the volumes that you move are removed. You
must also make sure that any copy pairs associated with the volumes that you move are removed for a single
source volume or a target volume in a copy pair.
For information about how to remove copy pairs, refer to the topics under SANtricity ES Storage Manager
Volume Copy, the corresponding PDF document on the SANtricity ES Storage Manager Installation DVD, or
the online help topics in the Array Management Window.
If a volume group that contains copy pairs is removed and reinstalled into the same storage array for security,
you do not need to remove the copy pairs before relocation. In this case, make sure that any volume copies
with a status of In Progress or Pending are stopped before you move the volume group. If you perform this
check, failure of the volume copies is prevented. For information, see "Exporting and Importing a Volume
Group."
SafeStore Drive Security
SafeStore Drive Security is a premium feature that prevents unauthorized access to the data on a Full Disk
Encryption (FDE) drive that is physically removed from the storage array. Controllers in the storage array
have a security key. Secure drives have hardware support for encryption and decryption and provide secure
access to data only through a controller that has the correct security key. All of the controllers in a storage
array must have the same security key.
To move security-enabled drives to a new storage array for additional capacity, you can first use the Secure
Erase option to erase the drives.
SANtricity_10.77 February 2011
LSI Corporation
- 846 -
To move a volume group that includes a security-enabled volume to a new storage array without loss of data,
you must also install the security key from the original storage array into the new storage array. Installing a
new security key in a storage array that previously had a different security key might result in data becoming
inaccessible. If the new storage array has a different security key installed and already has a security-enabled
volume, changing the security key will prevent access to the existing security-enabled volume.
Security capable drives can be used in volumes that are not security-enabled without enabling the drive
security feature. In that case, volume groups containing such drives can be relocated without regard for the
security key.
Data Assurance
The SafeStore Data Assurance (DA) premium feature checks for and corrects errors that might occur as data
is communicated between a host and a storage array. DA is implemented using the SCSI direct-access block-
device protection information model.
Only certain configurations of hardware that includ DA-capable drives support the DA premium feature. When
you install the DA premium feature on a storage array, SANtricity ES Storage Manager provides options to
use DA with certain operations. For example, you can create a volume group that includes DA-capable drives,
and then create a volume within that volume group that is DA-enabled.
When you move a volume group that includes a DA-enabled volume, the destination storage array must have
the DA premium feature installed to continue using the feature. If the feature is not installed on the destination
storage array, data will still be accessible on the volume without the error checking provided by DA.
Solid State Disk (SSD) Drives
The option to use Solid State Disk (SSD) drives in place of conventional drives is available as a premium
feature with some hardware. The FC4600 drive tray and the DE1600 drive tray can have SSD drives. If you
relocate a volume group that includes SSD drives, the destination hardware must support those drives.
Requirements for Moving Configured Hardware
Before you move any configured hardware, you must make sure that all of the requirements to move the
drives or the drive trays have been met. To make sure that all the requirements are met, complete all of the
tasks in this section.
ATTENTION Possible data loss or corruption – Export a volume group whenever possible. This
action makes sure that any volume groups or volumes that you move to different destination storage arrays
are correctly recognized and managed by the new storage array.

Moving Drives to a New Storage Array for Additional Capacity –
Data Is Preserved
IMPORTANT Data is not preserved when you move drives to a new storage array to obtain additional
capacity.
This procedure removes all data and configuration information from the drives so that you have unconfigured
drives that can be reused.
Relocation Process Overview
ATTENTION Possible loss of data – When you delete a volume group and its volumes, all data is
removed, which includes snapshot volumes and associated snapshot repository volumes. The associated
volumes return to an Unassigned status. You cannot cancel this operation after it starts. Use this option only if
you do not want to keep the data or volume information on the drives.
You can move drives from one storage array to a destination storage array to add unconfigured capacity to
the destination storage array. You must remove all volume group information and volume information from the
drives while they reside on the source storage array. This action prepares the drives so that they come online
automatically in the destination storage array and are ready to configure for use.
To move drives from one storage array to another to add unconfigured capacity, perform the following
procedures:
1. Check the status of the source storage array and the destination storage array.
2. Delete the volume groups from the source storage array.
3. Remove the drives from the source storage array.
4. Install the drives in the destination storage array.
5. Initialize the drives in the destination storage array.
6. Delete a volume group in the destination storage array.
When the procedure is completed, the drives are ready to configure and use.
Relocation Procedure
Complete the procedures in these sections to move drives from a source storage array to a new destination
storage array for additional capacity.
Checking the Status of the Source Storage Array and the Destination Storage Array
1. Make sure that the requirements to move the drives have been met.
For information, see "Understanding Concepts, Restrictions, and Requirements of Volume Group
Relocation."
IMPORTANT Depending on the size of the storage array, a full backup could take several hours or
several days.

Initializing the Drives in the Destination Storage Array
When volumes that were previously part of a multi-drive volume group are relocated from one storage array
to another, the volume groups can appear Offline in the Logical pane of the Array Management Window.
This situation occurs because the volume group information and the volume information about the drives are
incomplete.
To resolve the problem, you must initialize the drives. This action erases the volume group information and
the volume information and returns the selected drives to an Unassigned state. When you put the drives into
an Unassigned state, you add new capacity or additional unconfigured capacity to the storage array.
When the drives are initialized, the status of the drives changes to Unassigned. If a current Unconfigured
Capacity node exists, the raw capacity of the drives is added to it. Otherwise, a new Unconfigured Capacity
node is added to the Logical pane with the raw capacity of the drives added to it. When you initialize the
drives, all of the data is removed from the drives.
IMPORTANT If the status of the unexpected volume groups is Optimal, you must delete the volume
group. Go to “Deleting a Volume Group in the Destination Storage Array.”
After you have completed the procedure, the drives come online and are ready to be configured and used.
1. Make sure that the status of the volume group and its associated volumes is Offline.
These entities show an Offline status:
The volume group and the volume – If you move the mouse pointer over the volume group or
the volume in the Logical pane of the Array Management Window, a message shows the status as
Offline.
The drive needs attention – If you move the mouse pointer over the drives in the Physical pane of
the Array Management Window, a message shows the status as Offline.
ATTENTION Possible loss of data – If you initialize a drive, all of the volume information is
deleted, and the selected drives return to an Unassigned status. You cannot cancel this operation after it
starts.
2. From the Physical pane, select the drives that you want to initialize.
To select multiple drives, hold down the Ctrl key, and select the drives.
3. Select Advanced >> Recovery >> Initialize >> Drive.
4. To start the drive initialization process, type yes, and click OK.
When the storage arrays initialize, each volume icon shows as Operation in Progress in the Logical pane.
After the storage array initializes, the Array Management Window shows these conditions:
In the Physical pane, the status of the drives changes to Unassigned.
In the Logical pane, the volume group and all of its associated volumes are deleted, and their icons
are removed.
• If a current Unconfigured Capacity node exists, the raw capacity of the drives is added to it.
• If an Unconfigured Capacity node did not exist before the drive initialization operation, a new
Unconfigured Capacity node is added to the Logical pane. The raw capacity of the drives is
added to it.
5. To complete the relocation process, configure the drives.

Deleting a Volume Group in the Destination Storage Array
IMPORTANT If the status of the unexpected volume groups is Offline, you must initialize the drives. Go
to “Initializing the Drives in the Destination Storage Array.”
IMPORTANT You must restart the host system to permanently remove any information about the
deleted volumes.
If unexpected volume groups appear with a status of Optimal in the Logical pane after you have initialized the
drives in the destination storage array, you must delete all of the volume groups and any associated volumes.
This action removes the volume group information and the volume information.
When you delete the volume groups, the status of the drives that made up the capacity of the volume group
changes to an Unassigned status. If a current Unconfigured Capacity node exists, the raw capacity of the
drives is added to it. Otherwise, a new Unconfigured Capacity node is added to the Logical pane that contains
the raw capacity of the drives. All of the data is removed from the drives.
1. From the Logical pane, select the volume group that you want to delete.
2. Select Volume Group >> Delete.
ATTENTION Possible loss of data – If you delete a volume group and its volumes, this action
removes all of the data, which includes any snapshot volumes or snapshot repository volumes. The
associated drives return to an Unassigned status. You cannot cancel this operation after it starts.
3. In the Delete Volume Group dialog, select one or more volume groups.
4. Click Delete.
5. In the Confirm Delete Volume Group dialog, type yes to confirm the removal of the volume groups.

Exporting and Importing a Volume Group
For specific information about the export process and the import process, refer to the online help topics in the
Array Management Window.
Volume group relocation lets you export a volume group so that you can import the volume group to a
different storage array. You can also export a volume group so that you can store the data offline.
ATTENTION Possible loss of data access – You must export a volume group before you move the
volume group or import the volume group.
Exporting a Volume Group
The export volume group operation prepares the drives in the volume group for removal. You can remove the
drives for offline storage, or you can import the volume group to a different storage array. After you complete
the export volume group operation, all of the drives are offline. Any associated volumes or Free Capacity
nodes no longer appear in the storage management software.
Non-Exportable Components
You must remove any non-exportable components before you can complete the export volume group
procedure. You must remove these components:
Persistent reservations
Host-to-volume mappings
Volume copy pairs
Snapshot volumes and snapshot repository volumes
Remote mirror pairs
Mirror repositories
Showing Volume Group Export Dependencies
The exportDependencies command shows a list of dependencies for the drives in a volume group that
you want move from one storage array to a destination storage array.
For information about how to show volume group export dependencies, refer to the online help topics in the
Array Management Window.
Starting Volume Group Export
The export command moves a volume group into an Exported state so that you can remove the drives that
comprise the volume group and reinstall the drives in a destination storage array.
NOTE Within the volume group, you cannot move volumes that are associated with the premium
features from one storage array to another storage array.

Moving a Volume Group to a Different Storage Array – Data Is
Preserved
Relocation Process Overview
ATTENTION Possible data loss or corruption – Perform the hot volume group relocation whenever
possible. This action makes sure that any volume groups or volumes that you move to different destination
storage arrays are correctly recognized and managed by the new storage arrays.
IMPORTANT Use the procedures listed below only when you move a volume group from one storage
array to another (data is preserved).
To move a volume group from one storage array to another, perform these procedures. Each procedure has a
separate topic with detailed steps.
1. Locate the drives in the volume group.
2. Check the status of the source storage array and the destination storage array.
3. Remove the copy pairs.
4. Remove the mirror relationships.
5. Delete a snapshot volume.
6. Check the NVSRAM bit for the destination storage array.
7. Change the NVSRAM bit for the destination storage array (if needed).
8. Remove the drives from the source storage array.
9. Delete a missing volume.
10. Install the drives into the destination storage array.
11. Define new storage partitions.
12. Complete the volume group relocation.
Locating the Drives in a Volume Group
The drives that comprise a volume group usually are located in multiple drive trays in a storage array. If you
move a volume group from one storage array to another storage array, you are required to identify which
drives to relocate to the destination storage array. You are also required to identify which volume groups will
stay in the source storage array.
1. Based on whether snapshot volumes exist in the volume group, perform one of these actions:
Snapshot volumes exist in the volume group – Go to step 2.
Snapshot volumes do not exist in the volume group – Go to step 4.
IMPORTANT If you have created a snapshot volume of a base volume, in some cases, the
snapshot repository volume and base volume might reside in different volume groups. If you want to
keep the data in the snapshot volume, you must locate and move all of the volume groups that contain
snapshot repository volumes that are associated with the snapshot volume. If you do not move all of the
associated volumes, the snapshot volume will become unusable in both storage arrays.

from the pop-up menu.
3. In the Volume - Associated Components dialog, make sure that the snapshot repository volume is in the
same volume group as the snapshot volume, and perform one of these actions:
The snapshot repository volume is in a different volume group – Repeat step 2 for the volume
group that contains the snapshot repository volume. When you have completed these tasks for all of
the volume groups, go to step 4.
The snapshot repository volume is in the same volume group – Go to step 4.
4. Physically locate the drives in the selected volume group by activating the LED on each drive.
a. In the Logical pane, select the volume group.
A blue association dot appears under each drive in the volume group in the Array Management
Window.
b. Select Volume Group >> Locate.
The Locate Volume Group dialog appears, and the Drive LEDs blink above or below the drives in the
storage array.
5. Physically mark the drives in the storage array to identify whether the drive is part of a volume group that
stays in the source storage array or whether the drive is part of a volume group that you want to move to
the destination storage array.
6. To stop the blinking LEDs, in the Locate Volume Group dialog, click OK.
7. Repeat step 1 through step 6 for all of the volume groups that you want to remove from the storage array.
8. Go to “Checking the Status of the Source Storage Array and the Destination Storage Array.”

Installing the Drives into the Destination Storage Array
When you complete this procedure, the drives come online automatically in the storage array.
IMPORTANT Volume group numbering on the destination storage array might change after all of the
drives in the volume group are installed. The controller automatically assigns volume group numbering for
current volume groups and relocated volume groups.
If you have created a snapshot volume of a base volume, in some cases, the snapshot repository volume
and the base volume might reside in different volume groups. If you want to keep the data in the snapshot
volume, you must locate and move all of the volume groups that contain the snapshot repository volumes that
associated with the snapshot volume. If you do not move all of the associated volumes, the snapshot volume
will become unusable in both storage arrays.
1. Open the Enterprise Management Window.
2. Select the destination storage array in the Device table, and start its Array Management Window.
If the Array Management Window for the selected storage array is already open on the storage
management station, a second Array Management Window does not open.

The drives show a Needs Attention status in the Physical pane of the Array Management Window
until all of the drives from the volume group are installed.
9. Repeat step 5 through step 7 until all of the drives from the volume group are installed.
IMPORTANT The volume group shows an Offline status until all of the drives are installed. When
you install the last drive in the volume group, the volume can show a Failed status temporarily while the
controller is updating. When the update is completed, the volume group comes back online automatically
with an Optimal status.
10. When all of the drives have been installed, make sure that the volume group is back online by checking
the status indicators in the Array Management Window.
The volume group, the volume, and the snapshot repository volume show Optimal status
– If you move the mouse pointer on the volume group or volume in the Logical pane of the Array
Management Window, a message shows the status. A snapshot volume has an Optimal status
indicator or a Contingent status indicator.
The drive shows Assigned status and Optimal status – If you move the mouse pointer on the
drive in the Physical pane of the Array Management Window, a message shows the status.
11. When the volume group is back online, go to “Defining New Storage Partitions.”

1. Based on the status of storage partitions, perform one of these actions:
Storage partitions were deleted – If storage partitions were deleted while the volume group resided
in the source storage array, you must create new storage partitions when the volume group is
relocated to the destination storage array. If new storage partitions are not defined, hosts connected
to the destination storage array are not able to detect the volumes in the new volume group. Go to
step 3.
Volume-to-LUN mappings were changed to the Default Group – Go to step 2.
2. If you changed the host group for specific volume-to-LUN mappings to the Default Group while the
volume group resided in the source storage array, perform one of these actions:
You will use default mappings – The Default Group for the destination storage array detects the
volumes when you install the volume group in the destination storage array. Any hosts or host groups
in the Default Group of the destination storage array can access the volumes. Go to “Completing the
Volume Group Relocation.”
You will use Storage Partitioning – You can map a specific host or hosts to the volumes in the
destination storage array. Go to step 3.
3. To define a new storage partition, perform these actions:
a. Select a volume in the Topology pane of the Mappings tab.
b. To create a new volume-to-LUN mapping, select Mappings >> Define >> Storage Partitioning.
c. Follow the instructions on each dialog, and click Next when you are ready to move to the next dialog.
d. To complete the volume-to-LUN mapping, click Finish.
A dialog shows the progress of the processing.
e. To return to the Mappings, click OK.
4. Depending on whether you have additional volumes to map to hosts or host groups, perform one of these
actions:
You have additional volumes to map to hosts or host groups – Repeat step 3.
You are finished mapping volumes to hosts or host groups – Go to step 5.
5. Run the host hot_add utility, if applicable for your operating system.
6. Go to “Completing the Volume Group Relocation.”
Completing the Volume Group Relocation
1. Mount any file systems, if applicable, for the operating system.
2. Start the host applications that are associated with the volumes.
3. Create a storage array all support data collection for the source storage array that is affected by the
procedure.
a. Save the storage array all support data collection.
b. Open and view the storage array all support data collection files.
For information about creating a storage array all support data collection, see “Creating Storage Array All
Support Data Collections.”
4. Repeat step 3 for the destination storage array.

Moving a Drive Tray to a Different Storage Array – Data Is
Preserved
Relocation Process Overview
NOTE Data is preserved when you successfully follow the procedures listed in this section to move a
drive tray from the source storage array to a different destination storage array.
NOTE If you are moving a drive tray that has the DC power option, the destination storage array must
be cabled for DC power.
WARNING (W14) Risk of bodily injury – A qualified service person is required to make the DC
power connection according to NEC and CEC guidelines.
To move a drive tray with volume groups from one storage array to another storage array, perform these
procedures, which are described in detail in the corresponding topics:
1. Locate the drives in a volume group.
2. Check the status of the source storage array and the destination storage array.
3. Remove the copy pairs.
4. Remove the mirror relationships.
5. Delete a snapshot volume.
6. Check the NVSRAM bit on the destination storage array.
7. Change the NVSRAM bit on the destination storage array.
8. Remove and relocate the drives in the source storage array.
9. Remove the drive tray from the source storage array.
10. Turn on the power to the source storage array.
11. Delete a missing volume.
12. Install the drive tray into the destination storage array.
13. Install the drives into the destination storage array.
14. Define new storage partitions.
15. Complete the volume group relocation.
ATTENTION Possible loss of data or data corruption – Perform a hot volume group relocation
whenever possible. This action makes sure that any volume groups or volumes that you move to different
destination storage arrays are correctly recognized and managed by the new storage array.
Locating the Drives in a Volume Group
The drives that include a volume group usually are located in multiple drive trays in a storage array. If you
move a drive tray from one storage array to another storage array, you are required to identify which volume
groups that you want to relocate to the destination storage array. You are also required to identify which
volume groups will remain in the source storage array.
SANtricity_10.77 February 2011

You must move the drives that remain in the source storage array to drive trays that will remain within the
source storage array. The drives that you want to move to the destination storage array will be installed after
the drive tray has been moved to the destination storage array.
1. Based on whether snapshot volumes exist in the volume group, perform one of these actions:
Snapshot volumes exist in the volume group – Go to step 2.
Snapshot volumes do not exist in the volume group – Go to step 4.
IMPORTANT If you have created a snapshot volume of a base volume, in some cases, the
snapshot repository volume and the base volume might reside in different volume groups. To keep
the data in the snapshot volume, you must locate and move all of the volume groups that contain the
snapshot repository volumes that are associated with the snapshot volume. If you do not move all of the
associated volumes, the snapshot volume will become unusable in both storage arrays.
2. Locate the snapshot repository volume that is associated with the snapshot volume in the volume group
that you want to move.
a. Open the Enterprise Management Window.
b. Select the source storage array in the Device table, and start its Array Management Window.
If the Array Management Window for the selected storage array is already open on the storage

Removing and Relocating the Drives
In some cases, the drives that comprise a volume group might be split between a drive tray that you are
moving and another drive tray that will remain in the source storage array. This procedure applies to two such
situations:
A drive tray that you are moving contains some drives that belong to a volume group that will remain in
the source storage array. Move those drives to another drive tray in the source storage array.
A volume group you are moving to the destination storage array has some drives in a drive tray that you
are moving and others in a drive tray that will remain in the source storage array. Move the drives that are
needed for the volume group that you are moving. Move those drives from the drive tray that remains in
the source storage array to a drive tray in the destination storage array.
If the drive trays you are moving contain all of the drives used by the volume groups you are moving and
contain no drives used by other volume groups, go to "Moving the Drive Trays from the Source Storage Array
to the Destination Storage Array."

Installing the Drives into the Destination Storage Array
When you complete this procedure, the drives come online automatically in the storage array.
IMPORTANT Volume group numbering on the destination storage array might change after all of the
drives in the volume group are installed. The controller automatically assigns volume group numbering for
current volume groups and relocated volume groups.
If you have created a snapshot volume of a base volume, in some cases, the snapshot repository volume
and the base volume might reside in different volume groups. If you want to keep the data in the snapshot
volume, you must locate and move all of the volume groups that contain the snapshot repository volumes that
associated with the snapshot volume. If you do not move all of the associated volumes, the snapshot volume
will become unusable in both storage arrays.
1. Open the Enterprise Management Window.
2. Select the destination storage array in the Device table, and start its Array Management Window.
If the Array Management Window for the selected storage array is already open on the storage
management station, a second Array Management Window does not open.
3. Make sure that empty drive slots are available in the Physical pane of the Array Management Window for
the destination storage array.
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the
tray, use proper antistatic protection when handling tray components.
4. Put on antistatic protection.
5. Remove the blank drive canisters from the empty drive slots.
ATTENTION Possible damage to drives – If you bump drives against another surface, the drive
mechanism or connectors can be damaged. To avoid damage when you remove or install a drive, always
put your hand under the drive canister to support its weight. Do not touch the electronics on the drive.
6. Install the drive canisters, one at a time, into the destination storage array.
a. Install each drive in one complete motion by inserting it all the way into the slot.
b. Lower (close) the lever to lock the drive securely into place.
IMPORTANT Wait at least two minutes for the controller to write information before you
reinstall the next drive. If you install more than one drive and the controller is not given enough time to
recognize each drive, the storage array can enter into an Unstable status. If time is not available, you
must restart both controllers, which forces the controllers to write the information.
The volume group and its associated volumes will show an Offline status in the Array Management
Window until all the drives in the volume group are replaced.
IMPORTANT Snapshot volumes do not have an Offline status indicator.
These entities show an Offline status:
•The volume group, the volume, and the snapshot repository volume – If you move the
mouse pointer over the volume group or the volume in the Logical pane of the Array Management
Window, a message shows the status as Offline.
SANtricity_10.77 February 2011
LSI Corporation
- 887 -
•The drive needs attention – If you move the mouse pointer over the drives in the Physical pane
of the Array Management Window, a message shows the status as Offline.
7. Depending on whether the drive appears in the Physical pane of the Array Management Window, perform
one of these actions:
The drive appears in the Physical pane – The drive shows a Needs Attention status. Go to step 9.
The drive does not appear in the Physical pane – Go to step 8.
8. Reinstall the drive.
a. Open the lever, and pull the drive out of the drive tray approximately 5 cm (2 in.).
b. Wait at least two minutes for the drive to spin down.
c. Install the drive in one complete motion by inserting it all the way into the slot.
d. Lower (close) the lever to lock the drive securely in place.
e. Wait another two minutes until the drive appears in the Array Management Window before you install
the next drive.
The drives show a Needs Attention status in the Physical pane of the Array Management Window
until all of the drives from the volume group are installed.
9. Repeat step 5 through step 7 until all of the drives from the volume group are installed.
IMPORTANT The volume group shows an Offline status until all of the drives are installed. When
you install the last drive in the volume group, the volume can show a Failed status temporarily while the
controller is updating. When the update is completed, the volume group comes back online automatically
with an Optimal status.
10. When all of the drives have been installed, make sure that the volume group is back online by checking
the status indicators in the Array Management Window.
The volume group, the volume, and the snapshot repository volume show Optimal status
– If you move the mouse pointer on the volume group or volume in the Logical pane of the Array
Management Window, a message shows the status. A snapshot volume has an Optimal status
indicator or a Contingent status indicator.
The drive shows Assigned status and Optimal status – If you move the mouse pointer on the
drive in the Physical pane of the Array Management Window, a message shows the status.
11. When the volume group is back online, go to “Defining New Storage Partitions.”
Defining New Storage Partitions
Perform these steps if you had used Storage Partitioning to define volume-to-LUN mappings for a volume that
has been moved to the destination storage array.
IMPORTANT Storage Partitioning is a premium feature that you must enable before you create or
change volume-to-LUN mappings.
1. Based on the status of storage partitions, perform one of these actions:
Storage partitions were deleted – If storage partitions were deleted while the volume group resided
in the source storage array, you must create new storage partitions when the volume group is
relocated to the destination storage array. If new storage partitions are not defined, hosts connected
to the destination storage array are not able to detect the volumes in the new volume group. Go to
step 3.
Volume-to-LUN mappings were changed to the Default Group – Go to step 2.
SANtricity_10.77 February 2011
LSI Corporation
- 888 -
2. If you changed the host group for specific volume-to-LUN mappings to the Default Group while the
volume group resided in the source storage array, perform one of these actions:
You will use default mappings – The Default Group for the destination storage array detects the
volumes when you install the volume group in the destination storage array. Any hosts or host groups
in the Default Group of the destination storage array can access the volumes. Go to “Completing the
Volume Group Relocation.”
You will use Storage Partitioning – You can map a specific host or hosts to the volumes in the
destination storage array. Go to step 3.
3. To define a new storage partition, perform these actions:
a. Select a volume in the Topology pane of the Mappings tab.
b. To create a new volume-to-LUN mapping, select Mappings >> Define >> Storage Partitioning.
c. Follow the instructions on each dialog, and click Next when you are ready to move to the next dialog.
d. To complete the volume-to-LUN mapping, click Finish.
A dialog shows the progress of the processing.
e. To return to the Mappings tab, click OK.
4. Depending on whether you have additional volumes to map to hosts or host groups, perform one of these
actions:
You have additional volumes to map to hosts or host groups – Repeat step 3.
You are finished mapping volumes to hosts or host groups – Go to step 5.
5. Run the host hot_add utility, if applicable for your operating system.
6. Go to “Completing the Volume Group Relocation.”
Completing the Volume Group Relocation
1. Mount any file systems, if applicable, for the operating system.
2. Start the host applications that are associated with the volumes.
3. Create a storage array all support data collection for the source storage array that is affected by the
procedure.
a. Save the storage array all support data collection.
b. Open and view the storage array all support data collection files.
For information about creating a storage array all support data collection, see “Creating Storage Array All
Support Data Collections.”
4. Repeat step 3 for the destination storage array.

Failover Drivers
This topic describes how to use the various failover drivers for the Windows operating system, the Linux
operating system, and Solaris operating system with SANtricity ES Storage Manager Version 10.75.

Overview of Failover Drivers
Failover drivers provide redundant path management for storage devices and cables in the data path from the
host bus adapter to the controller. For example, you can connect two host bus adapters in the system to the
redundant controller pair in a storage array, with different buses for each controller. If one host bus adapter,
one bus cable, or one controller fails, the failover driver automatically reroutes input/output (I/O) to the good
path, which permits the storage array to continue operating without interruption.
Failover drivers provide these functions:
They automatically identify redundant I/O paths.
They automatically reroute I/O to an alternate controller when a controller fails or all of the data paths to a
controller fail.
They check the state of known paths to the storage array.
They provide status information on the controller and the bus.
They check to see if the Service mode is enabled and if the modes have switched between Redundant
Dual Active Controller (RDAC) and Auto-Volume Transfer (AVT).

Failover Driver Setup Considerations
Most storage arrays contain two controllers that are set up as redundant controllers. If one controller fails, the
other controller in the pair takes over the functions of the failed controller, and the storage array continues to
process data. You can then replace the failed controller and resume normal operation. You do not need to
shut down the storage array to perform this task.
The redundant controller feature is managed by the failover driver software, which controls data flow to the
controller pairs independent of the operating system (OS). This software tracks the current status of the
connections and can perform the switch-over without any changes in the OS.
Whether your storage arrays have the redundant controller feature depends on a number of items:
Whether the hardware supports it. Refer to the hardware documentation for your storage arrays to
determine whether the hardware supports redundant controllers.
Whether your OS supports certain failover drivers. Refer to the installation and support guide for your OS
to determine if your OS supports redundant controllers.
How the storage arrays are connected. The storage array must have two controllers installed in a
redundant configuration. Redundant controllers can be configured only as an active/active pair. In an
active/active pair, you can have multiple paths from the hosts to the active controller, and you perform
load balancing on all of the active paths. Each controller has specific volumes assigned to it automatically.
If one of the active controllers fails, the software automatically switches its assigned volumes to the other
active controller.

Failover Configuration Diagrams
You can configure failover in several ways. Each configuration has its own advantages and disadvantages.
This section describes these configurations:
Single-host configuration
Multi-host configuration
This section also describes how the storage management software supports redundant controllers.
NOTE For best results, use the multi-host configuration. It provides the fullest failover protection and
functionality in the event that a problem exists with the connection.
Single-Host Configuration
In a single-host configuration, the host system contains two host bus adapters (HBAs), with each HBA
connected to one of the controllers in the storage array. The storage management software is installed on the
host. The two connections are required for maximum failover support for redundant controllers.
Although you can have a single controller in a storage array or a host that has only one HBA port, you
do not have complete failover data path protection with either of those configurations. The cable and the
HBA become a single point of failure, and any data path failure could result in unpredictable effects on the
host system. For the greatest level of I/O protection, provide each controller in a storage array with its own
connection to a separate HBA in the host system.

Single-Host-to-Storage Array Configuration
1. Host System with Two Fibre Channel Host Bus Adapters
2. Fibre Channel Connection – Fibre Channel Connection Might Contain One or More Switches
3. Storage Array with Two Fibre Channel Controllers
Multi-Host Configuration
For best results, use the multi-host configuration. It provides the best failover protection and functionality in
the event that a problem exists with the connection.
In a multi-host configuration, two host systems are each connected by two connections to both of the
controllers in a storage array. SANtricity ES Storage Manager, including failover driver support, is installed on
each host.
Not every operating system supports this configuration. Consult the restrictions in the installation and support
guide specific to your operating system for more information. Also, the host systems must be able to handle
the multi-host configuration. Refer to the applicable hardware documentation.
Both hosts have complete visibility of both controllers, all data connections, and all configured volumes in a
storage array, plus failover support for the redundant controllers. However, in this configuration, you must use
caution when you perform storage management tasks (especially deleting and creating volumes) to make
sure that the two hosts do not send conflicting commands to the controllers in the storage arrays.
These items are unique to this configuration:
Both hosts must have the same operating system version and SANtricity ES Storage Manager version
installed.
SANtricity_10.77 February 2011
LSI Corporation
- 894 -
Both host systems must have the same volumes-per-host bus adapter capacity. This capacity is important
for failover situations so that each controller can take over for the other and show all of the configured
volume groups and volumes.
If the operating system on the host system can create reservations, the storage management software
honors them. This concept means that each host could have reservations to specified volume groups and
volumes, and only the software on that host can perform operations on the reserved volume group and
volume. Without reservations, the software on either host system is able to start any operation. Therefore,
you must use caution when you perform certain tasks that need exclusive access. Especially when you
create and delete volumes, make sure that you have only one configuration session open at a time (from
only one host), or the operations that you perform could fail.
Multi-Host-to-Storage Array Configuration
1. Two Host Systems, Each with Two Fibre Channel Host Bus Adapters
2. Fibre Channel Connections with Two Switches (Might Contain Different Switch Configurations)
3. Storage Array with Two Fibre Channel Controllers

The following figure shows how failover drivers provide redundancy when the host application generates a
request for I/O to controller A, but controller A fails. Use the numbered information to trace the I/O data path.

How a Failover Driver Responds to a Data Path Failure
One of the primary functions of the failover feature is to provide path management. Failover drivers monitor
the data path for devices that are not working correctly or for multiple link errors. If a failover driver detects
either of these conditions, the driver automatically performs these steps:
The failover driver checks the pair table for the redundant controller.
The failover driver forces volumes to the other controller and routes all I/O to the remaining active
controller.
The older version of RDAC notifies you that an error has occurred with the Service Action Required LEDs
on the storage array, and with a message that was sent to the error logs. The newer versions of RDAC
and MPIO only send a message to the error logs.
The failover driver performs a path failure if alternate paths to the same controller are available. If all of
the paths to a controller fail, RDAC performs a controller failure.
A drive failure plus a controller failure are considered a double failure. The storage management software
provides data integrity as long as all drive failures and controller failures are detected and fixed before more
failures occur.
SANtricity_10.77 February 2011
LSI Corporation

Responding to a Data Path Failure
Use the Major Event Log (MEL) to respond to a data path failure. The information in the MEL provides the
answers to these questions:
What is the source of the error?
What is required to fix the error, such as replacement parts or diagnostics?
The next step depends on whether you are a system administrator or a Customer and Technical Support
representative.
Responding to a Data Path Failure When You Are a System Administrator
Under most circumstances, contact your Customer and Technical Support representative any time a path
fails and the storage array notifies you of the failure. If your controller has failed and your storage array has
customer-replaceable controllers, replace the failed controller. Follow the manufacturer’s instructions for how
to replace a failed controller.
Responding to a Data Path Failure When You Are a Customer and Technical
Support Representative
Use the Recovery Guru in the storage management software to diagnose and fix the problem, if possible. If
you cannot fix the problem with the Recovery Guru, follow the manufacturer’s instructions for how to replace a
failed controller.

Load-Balancing Policies
Load balancing is the redistribution of read/write requests to maximize throughput between the server and the
storage array. Load balancing is very important in high workload settings or other settings where consistent
service levels are critical. The multi-path driver transparently balances I/O workload without administrator
intervention. Without multi-path software, a server sending I/O requests down several paths might operate
with very heavy workloads on some paths, while other paths are not used efficiently.
The multi-path driver determines which paths to a device are in an active state and can be used for load
balancing. The load-balancing policy uses one of three algorithms: round robin, least queue depth, or least
path weight. Multiple options for setting the load-balancing policies let you optimize I/O performance when
mixed host interfaces are configured. The load-balancing policies that you can choose depend on your
operating system. Load balancing is performed on multiple paths to the same controller but not across both
controllers.
Load-Balancing Policies That Are Supported by the Operating Systems
Operating System Multi-Path Driver Load-Balancing Policy
Windows MPIO DSM Round robin with subset, least
queue depth, weighted paths
Red Hat Enterprise Linux
(RHEL) RDAC Round robin with subset, least
queue depth
SUSE Linux Enterprise
(SLES) RDAC Round robin with subset, least
queue depth
Solaris MPxIO Round robin with subset
Least Queue Depth
The least queue depth policy is also known as the least I/Os policy or the least requests policy. This policy
routes the next I/O request to the data path on the controller that owns the volume that has the least
outstanding I/O requests queued. For this policy, an I/O request is simply a command in the queue. The type
of command or the number of blocks that are associated with the command is not considered. The least
queue depth policy treats large block requests and small block requests equally. The data path selected is
one of the paths in the path group of the controller that owns the volume.
Round Robin with Subset I/O
The round robin with subset I/O load-balancing policy routes I/O requests, in rotation, to each available
data path to the controller that owns the volumes. This policy treats all paths to the controller that owns the
volume equally for I/O activity. Paths to the secondary controller are ignored until ownership changes. The
basic assumption for the round robin with subset I/O policy is that the data paths are equal. With mixed host
support, the data paths might have different bandwidths or different data transfer speeds.
Least Weighted Paths
The least weighted paths policy assigns a weight factor to each data path to a volume. An I/O request is
routed to the path with the lowest weight value to the controller that owns the volume. If more than one data
path to the volume has the same weight value, the round-robin with subset path selection policy is used to
route I/O requests between the paths with the same weight value.

Configuring Failover Drivers for the Windows OS and the Linux
OS
NOTE This topic applies to both the Windows OS and the Linux OS.
Dividing I/O Activity Between Two RAID Controllers to Obtain the Best
Performance
For the best performance of a redundant controller system, use the storage management software to divide
I/O activity between the two RAID controllers in the storage array. You can use either the graphical user
interface (GUI) or the command line interface (CLI).
To use the GUI to divide I/O activity between two RAID controllers, perform one of these steps:
Specify the owner of the preferred controller of an existing volume – Select Volume >> Change >>
Ownership/Preferred Path in the Array Management Window.
NOTE You can also use this method to change the preferred path and ownship of all volumes in a
volume group at the same time.
Specify the owner of the preferred controller of a volume when you are creating the volume –
Select Volume >> Create in the Array Management Window.
To use the CLI, go to theCreate RAID Volume (Free Extent Based Select) online help topic for the command
syntax and description.
Changing the Preferred Path Online Without Stopping the Applications
You can change the preferred path setting for a volume or a set of volumes online and without stopping the
applications. If AVT is not enabled, the driver uses the new preferred path immediately. However, if AVT is
enabled, the driver does not recognize that the preferred path has changed until the next cycle of the state
change monitor. Therefore, the driver might continue to use the old preferred path for up to 60 seconds,
or for the period to which the ScanInterval parameter is set. Because the driver continues to use the
non-preferred path for a short period of time,the driver might trigger a volume not on preferred path Needs
Attention condition in the storage management software. This condition is removed as soon as the state
change monitor is run. A MEL event and an associated alert notification are delivered for the volume that
is not on preferred path condition. If the driver needs some time to recognize that the preferred path has
changed, you can configure the AVT alert delay period with the storage management software. The Needs
Attention reporting is postponed until the driver failback task has had a chance to run.
NOTE The newer versions of the RDAC driver and the DSM driver do not recognize any AVT status
change (enabled or disabled) until the next cycle of the state change monitor.

Failover Drivers for the Windows Operating System
The failover driver for hosts with Microsoft Windows operating systems is Microsoft Multipath I/O (MPIO) with
a Device Specific Module (DSM) for SANtricity ES Storage Manager.
Microsft Multipath Input/Output
Microsoft Multipath I/O (MPIO) provides an infrastructure to build highly available solutions for Windows
operating systems (OSs). MPIO uses Device Specific Modules (DSMs) to provide I/O routing decisions, error
analysis, and failover.
NOTE You can use MPIO for all controllers that run controller firmware version 6.19 or later. MPIO
is not supported for any earlier versions of the controller firmware, and MPIO cannot coexist on a server
with RDAC. If you have legacy systems that run controller firmware versions earlier than 6.19, you must use
RDAC for your failover driver. For SANtricity ES Storage Manager Version 10.10 and later and all versions of
SANtricity Storage Manager, the Windows OS supports only MPIO.
Windows OS Restrictions
The MPIO DSM failover driver comes in these versions:
32-bit (x86)
64-bit Intel (Itanium or IA64)
64-bit AMD/EM64T (x64)
These versions are not compatible with each other. Because multiple copies of the driver cannot run on the
same system, each subsequent release is backward compatible. In other words, a SANtricity ES Storage
Manager Version 10.60 failover driver supports storage management software version 9.23.
You can use the DSM driver for all of the controllers that run controller firmware version 6.19 or later. The
DSM driver is not supported for any earlier versions of the controller firmware, and it cannot coexist on a
server with RDAC. If you have legacy systems that run controller firmware versions earlier than 6.19, you
must use RDAC for your failover driver.
Native SCSI-2 Release/Reservation Commands in a Multipath Environment
If multiple paths exist to a single controller and a SCSI-2 release/reservation (R/R) is received for a volume,
the DSM driver selects one path to each controller and repeats the request (called a reservation path). This
function is necessary because the controllers cannot accept SCSI-2 R/R requests through multiple paths for
a given volume. After the reservation path has been established, subsequent I/O requests for a volume are
restricted to that path until a SCSI-2 release command is received. The DSM driver distributes the reservation
paths if multiple volumes are mapped to the host, which distributes the load across multiple paths to the same
controller.
Translating SCSI-2 Reservation/Release Commands to SCSI-3 Persistent
Reservations
The DSM driver also supports the ability to translate the SCSI-2 R/R commands into SCSI-3 persistent
reservations. This function allows a volume to use one of the previously mentioned load-balancing policies
across all of the available controller paths rather than being restricted to a single reservation path. This
SANtricity_10.77 February 2011
LSI Corporation
- 901 -
feature requires the DSM driver to establish a unique “reservation key” for each host. This key is stored in
the Registry and is named S2toS3Key. If this key is present, translations are performed, or else the “cloning”
method is used.
Per-Protocol I/O Timeout Values
The timeout value associated with a non-passthrough I/O requests, such as read/write requests, is based
on the MS driver's TimeOutValue parameter, as defined in the Registry. A feature within the DSM allows a
customized timeout value to be applied based on the protocol, such as Fibre Channel, SAS, or iSCSI, that a
path uses. Per-protocol timout values provide these benefits:
Without per-protocol timeout values, the TimeOutValue setting is global and affects all storage.
The TimeOutValue is typically reset when an HBA driver is upgraded.
For Windows Server 2003, the default disk timeout value may be adjusted based on the size of the I/O
request. Adjusting the default disk timeout value helps support legacy SCSI devices.
The DSM feature allows a more predictable timeout setting for Windows Server 2003 environments. For
information about the configurable parameters associated with this feature, go to Configuration Settings
for Windows DSM and Linux RDAC.
The per-protocol timeout values feature slightly modifies the way in which the SynchTimeout parameter is
evaluated. The SynchTimeout parameter determines the I/O timeout for synchronous requests generated
by the DSM driver. Examples include the SCSI-2 to SCSI-3 PR translations and inquiry commands used
during device discovery. It is important that the timeout value for the requests from the DSM driver be at least
as large as the per-protocol I/O timeout value. When a host boots, the DSM driver performs these actions:
If the value of the SynchTimeout parameter is defined in the Registry key of the DSM driver, record the
current value.
If the value of the TimeOutValue parameter of the MS driver is defined in the Registry, record the
current value.
Use the higher of the two values as the initial value of the SynchTimeout parameter.
If neither value is defined, use a default value of 10 seconds.
For each synchronous I/O request, the higher value of either the per-protocol I/O timeout or the
SynchTimeout parameter is used. For example:
If the value of the SynchTimeout parameter is 120 seconds, and the value of the TimeOutValue
parameter is 60 seconds, 120 seconds is used for the initial value.
If the value of the SynchTimeout parameter is 120 seconds, and the value of the TimeOutValue
parameter is 180 seconds, 180 seconds is used for the initial value of the synchronous I/O requests
for the DSM driver.
If the I/O timeout value for a different protocol (for example, SAS) is 60 seconds and the initial value
is 120 seconds, the I/O will be sent using a 120-second timeout.
Selective LUN Transfer
This feature limits the conditions under which the DSM will move a LUN to the alternative controller to three
cases:
1. When a DSM with a path to only one controller, the non-preferred path, discovers a path to the alternate
controller.
2. When an I/O request is directed to a LUN that is owned by the preferred path, but the DSM is attached to
only the non-preferred path.
SANtricity_10.77 February 2011
LSI Corporation
- 902 -
3. When an I/O request is directed to a LUN that is owned by the non-preferred path, but the DSM is
attached to only the preferred path.
Cases 2 and 3 have these user-configurable parameters that can be set to tune the behavior of this feature.
The maximum number of times that the LUN transfer will be issued. This parameter setting prevents a
continual ownership thrashing condition from occurring in cases where the controller tray or the controller-
drive tray is attached to another host that requires the LUN be owned by the current controller.
A time delay before LUN transfers are attempted. This parameter is used to de-bounce intermittent I/
O path link errors. During the time delay, I/O requests will be retried on the current controller to take
advantage of the possibility that another host might transition the LUN to the current controller.
For further information on these two parameters, go to Configuration Settings for Windows DSM and Linux
RDAC.
In the case where the host system is connected to both controllers and an I/O is returned with a 94/01 status
(the LUN is not owned and can be owned), the DSM will modify its internal data on which controller to use for
that LUN and reissue the command to the other controller. The DSM will not issue a LUN transfer command
to the controller tray or controller-drive tray to avoid interfering with other hosts that might be attached to that
controller tray or the controller-drive tray.
When the DSM detects that a volume-transfer operation is required, the DSM will not immediately issue the
command. It will delay for three seconds before sending the command to the controller tray or the controller-
drive tray. This delay is to attempt to batch together as many volume-transfer operations for other LUNs as
possible. This batching method is used because the controller single-threads volume transfer operations and
will reject additional transfer commands until the controller has completed the operation it is currently working
on. This single-threading behavior extends the period of time that I/Os are not being successfully serviced by
the controller tray or the controller-drive tray.
This feature will be enabled if these conditions exist:
The controller tray or the controller-drive tray does not have AVT enabled.
The DSM configurable parameter ClassicModeFailover is set to 1.
The DSM configurable parameter DisableLunRebalance is set to 4.
Windows Failover Cluster
Clustering for the Windows Server 2008 OS and the Windows Server 2008 R2 OS uses SCSI-3 persistent
reservations natively. As a result, the DSM driver does not perform translations for any SCSI-2 R/R
commands, and you can use one of the previously mentioned load-balancing policies across all controller
paths. Translations still occur if the DSM driver is running in a Windows Server 2003 OS-based environment.
When using clustering, set the DisableLunRebalance parameter to 3. For information about this
parameter, go to Configuration Settings for Windows DSM and Linux RDAC.
Reduced Failover Timing
Settings related to drive I/O timeout and HBA connection loss timeout are adjusted in the host operating
system so that failover does not occur when a controller is restarted. These settings provide protection from
exception conditions that might occur when both controllers in a controller tray or a controller-drive tray are
restarted at the same time, but they have the unfortunate side-effect of causing longer failover times than may
be tolerated by some application or clustered environments. Support for the reduced failover timing feature
includes support for reduced timeout settings, which result in faster failover response times.
The following restrictions apply to this feature:
SANtricity_10.77 February 2011
LSI Corporation
- 903 -
Only the Windows Server 2008 OS and the Windows Server 2008 R2 OS support this feature.
Non-enterprise products attached to a host must use controller firmware release 7.35 or higher.
Enterprise products attached to a host must use controller firmware release 7.6 or higher. For
configurations where a mix of earlier releases is installed, older versions are not supported.
When this feature is used with Windows Server Failover Cluster (WSFC) on the Windows Server 2008
OS, MPIO HotFix 970525 is required. The required HotFix is a standard feature for the Windows Server
2008 R2 OS.
Additional restrictions apply to storage array brownout conditions. Depending on how long the brownout
condition lasts, PR registration information for volumes might be lost. By design, WSFC periodically polls the
cluster storage to determine the overall health and availability of the resources. One action performed during
this polling is a PRIN READ_KEYS request, which returns registration information. Because a brownout
condition can cause blank information to be returned, WSFC interprets this as a loss of access to the drive
resource and attempts recovery by first failing that drive resource, and then performing a new arbitration.
NOTE Any condition that causes blank registration information to be returned, where previous requests
returned valid registration information, can cause the drive resource to fail. If the arbitration succeeds, the
resource is brought online. Otherwise, the resource remains in a failed state. One reason for an arbitration
failure is the combination of brownout condition and PnP timing issues if the HBA timeout period expires.
When the timeout period expires, the OS is notified of an HBA change and must re-enumerate the HBAs to
determine which devices no longer exist or, in the case where a connection is re-established, what devices
are now present.
The arbitration recovery process happens almost immediately after the resource is failed. This situation, along
with the PnP timing issue, can result in a failed recovery attempt. Fortunately, you can modify the timing of
the recovery process by using the cluster. exe command-line tool. Microsoft recommends changing the
following, where resource_name is a cluster disk resource, such as Cluster Disk 1:
cluster.exe resource “resource_name” /prop RestartDelay=4000
cluster.exe resource “resource_name” /prop RestartThreshold=5
The previous example changes the disk-online delay to four seconds and the number of online restarts to five.
The changes must be repeated for each drive resource. The changes will persist across reboots. To display
the current (or changed) settings, use the following command:
cluster.exe resource “resource_name” /prop
Another option exists to prevent the storage array from returning blank registration information. This option
takes advantage of the Active Persist Through Power Loss (APTPL) feature found in Persistent Reservations,
which ensures that the registration information persists through brownout or other conditions related to a
power failure. APTPL is enabled when a registration is initially made to the drive resource. WSFC does
not use the APTPL feature, but an option is provided in the LSI DSM to set this feature when a registration
request is made.
IMPORTANT Because the APTPL feature is not supported in WSFC, Microsoft does not recommend
its use. The APTPL feature should be considered as an option of last resort when the cluster. exe
options cannot meet the tolerances needed. If a cluster setup cannot be brought online successfully after
this option is used, the controller shell or SYMbol commands might be required to clear existing persistent
reservations.
SANtricity_10.77 February 2011
LSI Corporation
- 904 -
NOTE The APTPL feature within the DSM is enabled using the DSM utility with the - o (feature) option
by setting the SetAPTPLForPR option to 1. According to the SCSI specification, you must this option before
PR registration occurs. If you set this option after a PR registration occurs, take the disk resource offline, and
then bring the disk resource back online. If the DSM has set the APTPL option during registration, an internal
flag is set, and the DSM utility output from the -g option indicates this condition. The SCSI specification does
not provide a means for the initiator to query the storage array to determine the current APTPL setting. As a
result, the -g output from one node might show the option set, but another node might not. Interpret output
from the -g option with caution. By default, the DSM is released without this option enabled.
Wait Time Settings
When the failover driver receives an I/O request for the first time, the failover driver logs timestamp
information for the request. If a request returns an error and the failover driver decides to retry the request,
the current time is compared with the original timestamp information. Depending on the error and the amount
of time that has elapsed, the request is retried to the current owning controller for the LUN, or a failover
is performed and the request sent to the alternate controller. This process is known as a wait time. If the
NotReadyWaitTime value, the BusyWaitTime value, and the QuiescenceWaitTime value are greater
than the ControllerIoWaitTime value, they will have no effect.
For the Linux OS, the configuration settings can be found in the /etc/mpp.conf file. For the Windows OS,
the configuration settings can be found in the Registry under:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\<DSM_Driver>
In the preceding setting, <DSM_Driver> is the name of the OEM-specific driver. The default driver is named
mppdsm.sys. Any changes to the settings take effect the next time the host is restarted.
ATTENTION Possible loss of data access – If you change these settings from their configured
values, you might lose access to the storage array.

Path Congestion Detection and Online/Offline Path States
The path congestion detection feature allows the DSM driver to place a path offline based on the path I/
O latency. The DSM will automatically set a path offline when I/O response times exceed user-definable
congestion criteria. An administrator can manually place a path into the Admin Offline state. When a path is
either set offline by the DSM or by an administrator, I/O will be routed to a different path. The offline or admin
offline path will not be used for I/O until the system administrator sets the path online.

DSM and Linux RDAC.
Configuration Settings for Windows DSM and Linux RDAC
This topic applies to both the Windows OS and the Linux OS. The failover driver that is provided with the

dsmUtil Utility
The dsmUtil utility is a command-line driven utility that works only with the Multipath I/O (MPIO) Device
Specific Module (DSM) solution. The utility is used primarily as to tell the DSM driver to perform various
maintenance tasks, but the utility can also serve as a troubleshooting tool when necessary.
Configuration Settings for Windows DSM and Linux RDAC
This topic applies to both the Windows OS and the Linux OS. The failover driver that is provided with the
storage management software contains configuration settings that can modify the behavior of the driver.
For the Linux OS, the configuration settings are in the /etc/mpp.conf file.
For the Windows OS, the configuration settings are in the HKEY_LOCAL_MACHINE\System
\CurrentControlSet\ Services\<DSM_Driver>\Parameters registry key, where
<DSM_Driver> is the name of the OEM-specific driver.
The default driver is mppdsm.sys. Any changes to the settings take effect on the next reboot of the host.
The default values listed in the following table apply to both the Windows OS and the Linux OS unless the OS
is specified in parentheses. Many of these values are overridden by the failover installer for the Linux OS or
the Windows OS.
ATTENTION Possible loss of data access – If you change these settings from their configured
values, you might lose access to the storage array.

Configuration Settings for the Path Congestion Detection Feature
Parameter Name Default
Value Description
CongestionDetectionEnabled 0x0 A Boolean value that indicates
whether the path congestion detection
is enabled. If this parameter is not
defined or is set to 0x0, the value
is false, the path congestion feature
is disabled, and all of the other
parameters are ignored. If set to
0x1, the path congestion feature is
enabled. Valid values are 0x0 or 0x1.
CongestionResponseTime 0x0 If CongestionIoCount is 0x0 or
not defined, this parameter represents
an average response time in seconds
allowed for an I/O request. If the
value of the CongestionIoCount
parameter is non-zero, then this
parameter is the absolute time
allowed for an I/O request. Valid
values range from 0x1 to 0x10000
(approximately 18 hours).
CongestionIoCount 0x0 The number of I/O requests that
have exceeded the value of the
CongestionResponseTime
parameter within the value of the
CongestionTimeFrame parameter.
Valid values range from 0x0 to
0x10000 (approximately 4000
requests).
SANtricity_10.77 February 2011
LSI Corporation
- 917 -
Parameter Name Default
Value Description
CongestionTimeFrame 0x0 A sliding window that defines the time
period that is evaluated in seconds. If
this parameter is not defined or is set
to 0x0, the path congestion feature is
disabled because no time frame has
been defined. Valid values range from
0x1 to 0x1C20 (approximately two
hours).
CongestionSamplingInterval 0x0 The number of I/O requests that
must be sent to a path before the
nth request is used in the average
response time calculation. For
example, if this parameter is set to
100, every 100th request sent to
a path will be used in the average
response time calculation. If this
parameter is set to 0x0 or not
defined, the path congestion feature
is disabled for performance reasons
—every I/O request would incur a
calculation. Valid values range from
0x1 to 0xFFFFFFFF (approximately 4
billion requests).
CongestionMinPopulationSize 0x0 The number of sampled I/O requests
that must be collected before the
average response time is calculated.
Valid values range from 0x1 to
0xFFFFFFFF (approximately 4 billion
requests).
CongestionTakeLastPathOffline 0x0 A Boolean value that indicates
whether the DSM driver will take the
last path available to the storage
array offline if the congestion
thresholds have been exceeded. If
this parameter is not defined or is set
to 0x0, the value is false. Valid values
are 0x0 or 0x1.
NOTE Setting a path offline
with the dsmUtil utility succeeds
regardless of the setting of this value.

dsmUtil Parameters
Parameter Description
-a [ target_id ]Shows a summary of all storage arrays seen by the DSM. The
summary shows the target_id, the storage array WWID, and the
storage array name. If target_id is specified, DSM point-in-time
state information appears for the storage array. On UNIX operating
systems, the virtual HBA specifies unique target IDs for each storage
array. The Windows MPIO virtual HBA driver does not use target IDs.
The parameter for this option can be viewed as an offset into the DSM
information structures, with each offset representing a different storage
array.
NOTE For use by Customer and Technical Support
representatives only.
-c array_name |
missing
Clears the WWN file entries. This file is located in the Program
Files\DSMDrivers\mppdsm\WWN_FILES directory with the
extension .wwn. If the array_name keyword is specified, the WWN
file for the specific storage array is deleted. If the missing keyword is
used, all WWN files for previously attached storage arrays are deleted.
If neither keyword is used, all of the WWN files, for both currently
attached and previously attached storage arrays, are deleted.
-d debug_level Sets the current debug reporting level. This option only works if the
RDAC driver has been compiled with debugging enabled. Debug
reporting is comprised of two segments. The first segment refers to
a specific area of functionality, and the second segment refers to the
level of reporting within that area. The debug_level is one of these
hexadecimal numbers:
0x20000000 – Shows messages from the RDAC driver’s
initialization routine.

SaveSettings]
Troubleshoots a feature or changes a configuration setting. Without
the SaveSettings keyword, the changes only affect the in-memory
state of the variable. The SaveSettings keyword changes both the
in-memory state and the persistent state. Some example commands
are:
dsmUtil -o – Displays all the available feature action names.
dsmUtil -o DisableLunRebalance=0x3 – Turns off the
DSM-initiated storage array LUN rebalance (affects only the in-
memory state).
-P
[GetMpioParameters

Displays and sets MPIO parameters.
NOTE For use by Customer and Technical Support
representatives only.
-R Remove the load-balancing policy settings for inactive devices.
-s ["failback"
| "avt" |
"busscan" |
"forcerebalance"]
Manually initiates one of the DSM driver’s scan tasks. A “failback”
scan causes the DSM driver to reattempt communications with any
failed controllers. An “avt” scan causes the DSM driver to check
whether AVT has been enabled or disabled for an entire storage
array. A “busscan” scan causes the DSM driver to go through
its unconfigured devices list to see if any of them have become
configured. A “forcerebalance” scan causes the DSM driver to move
storage array volumes to their preferred controller and ignores the
value of the DisableLunRebalance configuration parameter of the
DSM driver.

Device Manager
Device Manager is part of the Windows operating system. Select Control Panel from the Start menu. Then
select Administrative Tools >> Computer Management >> Device Manager.
The Device Manager tree for MPIO is similar to the one for RDAC. One difference is the names that are
associated with the volumes. In RDAC, the volumes are identified with a label, such as the RDAC Volume. In
MPIO, the volumes are named based on the vendor information and product ID information of the underlying
physical device, along with the text Multi-Path Disk Device.

Scroll down to System Devices to view information about the DSM driver itself. This name might be different
based on your network configuration.
The Drives section shows both the drives identified with the HBA drivers and the volumes created by MPIO.
Select one of the MPIO volumes, and right-click it. Select Properties to open the Multi-Path Disk Device
Properties window.
This properties window shows if the device is working correctly. Select the Driver tab to view the driver
information.
Determining if a Path Has Failed
If a single path to a controller that has multiple paths fails, the failover driver makes an entry in the OS system
log that indicates a path failure. In the storage management software, the storage array shows a Degraded
status.
If all of the paths to a controller fail, the failover driver makes entries in the OS system log that indicate a
path failure and failover. In the storage management software, the storage array shows a Needs Attention
condition of Volume not on preferred path. The failover event is also written to the Major Event Log (MEL). In
addition, if the administrator has configured alert notifications, email messages, or SNMP traps, messages
are posted for this condition. The Recovery Guru in the storage management software provides more
information about the path failure, along with instructions about how to correct the problem.
NOTE Alert reporting for the Volume not on preferred path condition can be delayed if you set the
failover alert delay parameter through the storage management software. When you set this parameter, it
imposes a delay on the setting of the Needs Attention condition in the storage management software.
Frequently Asked Questions About Windows Failover Drivers
Frequently Asked Questions about Windows Failover Drivers
Question Answer
My disk devices or host bus adapters (HBAs)
show a yellow exclamation point. What does
this mean?
When you use Device Manager, you might
observe that a disk device icon or an HBA
icon has a yellow exclamation point on it. If
new volumes have been mapped to the host,
the exclamation point might appear on the
icon for a few seconds. This action occurs
because the PnP Manager is reconfiguring
the device, and, during this time, the device or
the HBA might not be used. If the exclamation
point stays for more than one minute, a
configuration error has occurred.
My disk devices or HBAs show a red X. What
does this mean? When you use Device Manager, you might
notice that a disk device icon or an HBA
icon has a red X on it. This X indicates that
the device has been disabled. A disabled
device cannot be used or communicated with
until it is re-enabled. If the disabled device

Question Answer
is an adapter, any disk devices that were
connected to that adapter are removed from
Device Manager.
Why does the SMdevices utility not show any
volumes? If the SMdevices utility does not show any
volumes, perform these steps:
1. Make sure that all cables are seated
correctly. Make sure that all gigabit
interface converters (GBICs) are seated
correctly.
2. Determine the HBA BIOS and driver
versions that the system uses, and
make sure that the HBA BIOS and driver
versions are correct.
3. Make sure that your mappings are
correct. Do not use any HBA mapping
tools.
4. Use WinObj to determine if the host has
detected the volumes.
If the host has not detected the volumes,
an HBA problem or a controller problem
has occurred. Make sure that the HBAs are
logging into the switch or the controller. If they
are not logging in, the problem is probably
HBA related. If the HBAs have logged into
the controller, a controller issue might be the
problem.
The SMdevices utility shows duplicate entries
for some or all of my disks. You see that some of your disks show up
twice when you run the SMdevices utility.
For the Windows Server OS, something went
wrong with the device-claiming process.
I run the hot_add utility, but my disks do not
appear. See “Why does the SMdevices utility not
show any volumes?
I have mapped new volumes to my host, but I
cannot see them. Run the hot_add utility.
See “Why does the SMdevices utility not
show any volumes?”
How do I know if a host has detected my
volumes? Use WinObj to determine if the host can see
the volumes.
If the host cannot see the volumes, an
HBA problem or a controller problem has
occurred.
Make sure that the HBAs log into the
switch or the controller. If they are not
logging in correctly, the problem is
probably HBA related.
SANtricity_10.77 February 2011
LSI Corporation
- 923 -
Question Answer
If the HBAs have logged into the
controller, the problem might be a
controller issue.
When I boot my system, I get a “Registry
Corrupted” message. Refer to the Microsoft Knowledge Base article
277222 at http://support.microsoft.com/
kb/277222/en-us.
Registry limitations can result in devices and
paths that are not recognizable by the host
OS and the failover driver.
My controller failover test does not fail over. Make sure that you have looked through the
rest of this document for the problem. If you
think that the problem is still RDAC-related
or DSM-related, contact a Customer and
Technical Support representative.
After I install the DSM driver, my system takes
a long time to start. Why? You might still experience long start times
after you install the DSM driver because the
Windows OS is completing its configuration
for each device.
For example, you install the DSM driver on
a host with no storage array attached, and
you restart the host. Before the Windows
OS actually starts, you plug in a cable to a
storage array with 32 volumes. In the start-
up process, PnP detects the configuration
change and starts to process it. After the
configuration change has completed,
subsequent restarts do not experience
any delays unless additional configuration
changes are detected. The same process can
occur even if the host has already started.
What host type must I use for the MPIO
solution? If you use Microsoft Cluster Server, select
a host type of the Windows 2003/2008
Clustered OS. If you do not use Microsoft
Cluster Server, select a host type of the
Windows 2003/2008 Non-Clustered OS.
How can I tell if MPIO is installed? Perform these steps:
1. Go to the Control Panel on the Start
menu, and double-click Administrative
Tools.
2. Select Computer Management >>
Device Manager >> SCSI and RAID
controllers.
3. On Windows Server 2003, look for Multi-
Path Support. On Windows Server 2008,
look for Microsoft Multi-Path Bus Driver.
If one of these items is present, MPIO is
installed.

Question Answer
How can I tell if the DSM driver is installed? Perform these steps:
1. Go to the Control Panel on the Start
menu, and double-click Administrative
Tools.
2. Select Computer Management >>
Device Manager >> System Devices.
3. Look for the LSI-supported DSM. The
name ends with the text Device-Specific
Module for Multi-Path. If it is present,
DSM is installed.
What is the default vendor ID string and the
product ID string? By default, the vendor ID string and the
product ID string configured for LSI storage
arrays are named LSI/INF-01-00. If not, the
PnP manager cannot choose the failover
driver to manage the volume. The driver takes
over, which causes delays. If you suspect that
this event has occurred, check the non-user
configuration region of the controller firmware
What should I do if I receive this message?
Warning: Changing the storage
array name can cause host
applications to lose access to
the storage array if the host
is running certain path failover
drivers.
If any of your hosts are running
path failover drivers, please
update the storage array name
in your path failover driver’s
configuration file before
rebooting the host machine to
insure uninterrupted access to the
storage array. Refer to your path
failover driver documentation for
more details.
You do not need to update files. The
information is dynamically created only when
the storage array is found initially. Use one of
these two options to correct this behavior:
Restart the host server.
Unplug the storage array from the host
server, and perform a rescan of all of the
devices. After the devices have been
removed from the storage array, you can
re-attach them. Another rescan takes
place, which rebuilds the information with
the updated names.

The Linux OS RDAC driver cannot coexist with a Fibre Channel host bus adapter (HBA)-level multi-path
failover or failback driver, such as these:
The 8.00.00-fo or 8.00.02-fo Linux OS device driver for the IBM DS4000 fc2-133 host bus adapters driver
on servers with Intel architecture processors or AMD architecture processors
The QLA driver for the Fibre Channel expansion adapters on the IBM LoP blade servers
You might have to modify the makefile of the HBA driver for it to be compiled in the non-failover mode.
Auto-Volume Transfer (AVT) mode is automatically enabled in the SANshare Storage Partitioning host type in
the Linux OS. This mode causes contention when RDAC is installed, so you must disable it before you install
RDAC. Also, there is a separate Linux OS host type in which AVT is already disabled.
When the RDAC driver detects that all paths to a storage array have failed, it reports I/O failure immediately.
This behavior is different from the behavior of the failover device driver from IBM for the Fibre Channel HBA.
The Fibre Channel HBA failover device driver waits for a certain timeout or retry period before reporting an I/O
failure to the host application.
The cluster support feature in the Linux OS RDAC driver is only available for controller firmware version
5.4x.xx.xx or later. If a SCSI-2 reserve command or a SCSI-2 release command is addressed to a volume on
a storage array that runs a firmware version earlier than 5.40, a check condition is returned.
LoP servers do not support clustering with this Linux OS RDAC.
For LoP servers, the modprobe command is not supported with this Linux OS RDAC release on SUSE SLES
9 when the Linux OS RDAC driver is installed. Use the insmod command to remove and recover the device
driver stack. On LoP pSeries servers with more than three processors, if you use the modprobe command, it
might result in a hung server or panics.
Do not assign a universal access volume to LUN ID 0, especially with RDAC installed. If you place a universal
access volume at LUN ID 0, it might lead to loss of volume recognition of next sequence LUN IDs or a partial
list of virtual volumes reported with the RDAC driver. Assign these volumes to LUN ID 31.
For LoP servers, the HBA hot-swap procedure to remove a live, fully functioning Fibre Channel HBA causes
a system panic if the I/O is not diverted from that path first. This functionality is only supported on current 2.6
kernel versions. The work-around is to pull the Fibre Channel cable first, wait two minutes to five minutes for
failover to complete, and then run the drslot_chrp_pci -r -s slot-number command.

The Linux operating system includes a new method of kernel dump (kdump/kexec) to replace the previous
LKCD (Linux Kernel Crash Dump) method for SUSE and diskdump method for RHEL. If kdump is configured,
kdump and kexec work together to capture kernel exceptions, save the kernel state/memory and start a
second kernel image for debugging the troubled kernel. The second kernel is called kdump kernel. Kexec
and kdump are useful for troubleshooting panic conditions. With the current installation and driver build
method, the RDAC driver modules are not included in the kdump kernel initrd image. An initrd image contains
all necessary device driver modules that are used after the kernel image is loaded and before user space
initialization is started. Because the RDAC driver modules are not included in the kdump initrd image, a user
experiences these problems when kdump is configured: long boot times and the inability to save vmcore
file in a SAN boot configuration. The RDAC driver installation will build a kdump kernel initrd image with the
RDAC driver modules inside. Also, when the RDAC driver is installed, it will detect that a kdump kernel is
configured, and update the initrd image with the RDAC drivers.
Unique Features of RDAC from LSI
Redundant Dual Active Controller is the failover driver for the Linux OS that is included in SANtricity ES
Storage Manager. The RDAC failover driver includes these unique features:
On-the-fly path validation.
Cluster support.
Automatic detection of path failure. The RDAC failover driver automatically routes I/O to another path in
the same controller or to an alternate controller, in case all paths to a particular controller fail.
Retry handling is improved, because the RDAC driver can better understand the controller-returned sense
key/ASC/ASCQ of vendor-specific statuses of LSI.
Automatic rebalance is handled. When the failed controller obtains Optimal status, storage array
rebalance is performed automatically without user intervention.
Three load-balancing policies are supported: round robin subset, least queue depth, and path weight.
Configuration Settings for Windows DSM and Linux RDAC
This topic applies to both the Windows OS and the Linux OS. The failover driver that is provided with the
storage management software contains configuration settings that can modify the behavior of the driver.
For the Linux OS, the configuration settings are in the /etc/mpp.conf file.
For the Windows OS, the configuration settings are in the HKEY_LOCAL_MACHINE\System
\CurrentControlSet\Services\<DSM_Driver>\Parameters registry key, where <DSM_Driver>
is the name of the OEM-specific driver
The default driver is mppdsm.sys. Any changes to the settings take effect on the next reboot of the host.
The default values listed in the following table apply to both Windows and Linux unless the OS is specified in
parentheses. Many of these values are overridden by the failover installer for the Linux OS or the Windows
OS.
ATTENTION Possible loss of data access – If you change these settings from their configured
values, you might lose access to the storage array.

Prerequisites for Installing RDAC on the Linux OS
Before installing RDAC on the Linux operating system, make sure that your storage array meets these
conditions:
Make sure that the host system on which you want to install the RDAC driver has supported HBAs.
Refer to the installation electronic document topics for your controller tray or controller-drive tray for any
configuration settings that you need to make.
Although the system can have Fibre Channel HBAs from multiple vendors or multiple models of Fibre
Channel HBAs from the same vendor, you can connect only the same model of Fibre Channel HBAs to
each storage array.
Make sure that the low-level HBA driver has been correctly built and installed before RDAC driver
installation.
The standard HBA driver must be loaded before you install the RDAC driver. The HBA driver has to be a
non-failover driver.
For LSI HBAs, the port driver is named mptbase, and the host driver is named mptscsi or mptscsih,
although the name depends on the driver version. The Fibre Channel driver is named mptfc, the SAS
driver is named mptsas, and the SAS2 driver is named mpt2sas.
For QLogic HBAs, the base driver is named qla2xxx, and host driver is named qla2300. The 4-GB
HBA driver is named qla2400.
For IBM Emulex HBAs, the base driver is named lpfcdd or lpfc, although the name depends on the
driver version.
For Emulex HBAs, the base driver is named lpfcdd or lpfc, although the name depends on the driver
version.
Make sure that the kernel source tree for the kernel version to be built against is already installed. You
must install the kernel source rpm on the target system for the SUSE SLES operating system. You are
not required to install the kernel source for the Red Hat operating system.
Make sure that the necessary kernel packages are installed: source rpm for the SUSE Linux Enterprise
Server operating system and kernel headers/kernel devel for the Red Hat Enterprise Linux
operating system.
In SUSE operating systems, you must include these items for the HBAs mentioned as follows:
SANtricity_10.77 February 2011
LSI Corporation
- 932 -
For LSI HBAs, INITRD_MODULES includes mptbase and mptscsi (or mptscsih) in the /etc/
sysconfig/kernel file. The Fibre Channel driver is named mptfc, the SAS driver is named mptsas,
and the SAS2 driver is named mpt2sas.
For QLogic HBAs, INITRD_MODULES includes a qla2xxx driver and a qla2300 driver in the /etc/
sysconfig/kernel file.
For IBM Emulex HBAs, INITRD_MODULES includes an lpfcdd driver or an lpfc driver in the /etc/
sysconfig/kernel file.
For Emulex HBAs, INITRD_MODULES includes an lpfcdd driver or an lpfc driver in the /etc/
sysconfig/kernel file.
Installing SANtricity ES Storage Manager and RDAC on the Linux OS
IMPORTANT SANtricity ES Storage Manager requires that the different Linux OS kernels have
separate installation packages. Make sure that you are using the correct installation package for your
particular Linux OS kernel.
1. Open the installation program on the SANtricity ES Storage Manager Installation DVD.
The SANtricity ES Storage Manager installation window appears.
2. Click Next.
3. Accept the terms of the license agreement, and click Next.
4. Select one of the installation packages:
Typical – Select this option to install all of the available host software.
Management Station – Select this option to install software to configure, manage, and monitor a
storage array. This option does not include RDAC. This option only installs the client software.
Host – Select this option to install the storage array server software.
Custom – Select this option to customize the features to be installed.
NOTE For this procedure, Typical is selected. If the Host installation option is selected, the Agent,
the Utilities, and the RDAC driver will be installed.
You might receive a warning after you click Next. The warning states:
Existing versions of the following software already reside on
this computer ... If you choose to continue, the existing
versions will be overwritten with new versions ....
If you receive this warning and want to update to SANtricity ES Storage Manager Version 10.75, click OK.
5. Click Install.
You will receive a warning after you click Install. The warning tells you that the RDAC driver is not
automatically installed. You must manually install the RDAC driver.
The RDAC source code is copied to the specified directory in the warning message. Go to that directory,
and perform the steps in Installing RDAC Manually on the Linux OS.
6. Click Done.
Installing RDAC Manually on the Linux OS
1. To unzip the RDAC tar.gz file and untar the RDAC tar file, type this command, and press Enter:
tar -zxvf <filename>
SANtricity_10.77 February 2011
LSI Corporation
- 933 -
2. Go to the Linux RDAC directory.
3. Type this command, and press Enter.
make uninstall
4. To remove the old driver modules in that directory, type this command, and press Enter:
make clean
5. To compile all driver modules and utilities in a multiple CPU server (SMP kernel), type this command, and
press Enter:
make
6. Type this command, and press Enter:
make install
These actions result from running this command:
The driver modules are copied to the kernel module tree.
The new RAMdisk image (mpp-`uname -r`.img) is built, which includes the RDAC driver modules
and all driver modules that are needed at boot.
7. Follow the instructions shown at the end of the build process to add a new boot menu option that uses /
boot/mpp-`uname -r`.img as the initial RAMdisk image.
Making Sure that RDAC Is Installed Correctly on the Linux OS
1. Restart the system by using the new boot menu option.
2. Make sure that these driver stacks were loaded after restart:
scsi_mod
sd_mod
sg
mppUpper
The physical HBA driver module
mppVhba
3. Type this command, and press Enter:
/sbin/lsmod
4. To make sure that the RDAC driver discovered the available physical volumes and created virtual
volumes for them, type this command, and press Enter:
/opt/mpp/lsvdev
You can now send I/O to the volumes.
5. If you make any changes to the RDAC configuration file (/etc/mpp.conf) or the persistent binding file
(/var/mpp/devicemapping), run the mppUpdate command to rebuild the RAMdisk image to include
the new file. In this way, the new configuration file (or persistent binding file) can be used on the next
system restart.
6. To dynamically reload the driver stack (mppUpper, physical HBA driver modules, mppVhba) without
restarting the system, perform these steps:
a. To unload the mppVhba driver, type this command, and press Enter:
SANtricity_10.77 February 2011
LSI Corporation
- 934 -
rmmod mppVhba
b. To unload the physical HBA driver, type this command, and press Enter:
modprobe -r "physical hba driver modules"
c. To unload the mppUpper driver, type this command, and press Enter:
rmmod mppUpper
d. To reload the mppUpper driver, type this command, and press Enter:
modprobe mppUpper
e. To reload the physical HBA driver, type this command, and press Enter:
modprobe "physical hba driver modules"
f. To reload the mppVhba driver, type this command, and press Enter:
modprobe mppVhba
7. Restart the system whenever there is an occasion to unload the driver stack.
IMPORTANT Using the modprobe command with the RDAC driver stack or using the rmmod
command to remove all the drivers in the RDAC driver stack, in order, is not recommended nor
supported.
8. Disable Auto-Volume Transfer (AVT) by issuing a set controller command line interface (CLI) command.
For example, to disable AVT for host region 6 and controller A, use this command:
set controller[a] hostNVSRAMByte[0x6, 0x24]=0x00;
9. Use a utility, such as devlabel, to create user-defined device names that can map devices based on a
unique identifier, called a UUID.
10. Use the udev command for persistent device names. The udev command dynamically generates device
name links in the /dev/disk directory based on path, ID or UUID.
linux-kbx5:/dev/disk # ls /dev/disk by-id by-path by-uuid
For example, the /dev/disk/by-id directory links volumes that are identified by WWIDs of the
volumes to actual disk device nodes.

for the specified virtual_target_id.
-I host_num Prints the maximum number of targets that
can be handled by that host. Here, host
refers to the HBA drivers on the system and
includes the RDAC driver. The host number
of the HBA driver is given as an argument.
The host numbers assigned by the Linux
middle layer start from 0. If two ports are on
the HBA card, host numbers 0 and 1 would be
taken up by the low-level HBA driver, and the
RDAC driver would be at host number 2. Use
/proc/scsi to determine the host number.
-o feature_action_name [= value ][,
SaveSettings]
Troubleshoots a feature or changes
a configuration setting. Without the
SaveSettings keyword, the changes affect
only the in-memory state of the variable. The
SaveSettings keyword changes both the
in-memory state and the persistent state. You
must run mppUpdate to reflect these changes
in the inird image before rebooting the server.
Some example commands are:
mppUtil -o – Displays all the available
feature action names.

(affects only the in-memory state).
-s ["failback" | "avt" | "busscan"
| "forcerebalance"]
Manually initiates one of the RDAC driver’s
scan tasks.
A “failback” scan causes the RDAC driver
to reattempt communications with any
failed controllers.
An “avt” scan causes the RDAC driver to
check whether AVT has been enabled or
disabled for an entire storage array.
A “busscan” scan causes the RDAC
driver to go through its unconfigured
devices list to see if any of them have
become configured.
A “forcerebalance” scan causes
the RDAC driver to move storage
array volumes to their preferred
controller and ignore the value of the
DisableLunRebalance configuration
parameter of the RDAC driver.
-S Reports the Up state or the Down state of the
controllers and paths for each LUN in real
time.
-U Refreshes the Universal Transport
Mechanism (UTM) LUN information in MPP
driver internal data structure for all the storage
arrays that have already been discovered.
-V Prints the version of the RDAC driver
currently running on the system.
-w target_wwn , controller_index For use by Customer and Technical Support
representatives only.
Frequently Asked Questions about Linux Failover Drivers
Frequently Asked Questions about Linux Failover Drivers
Question Answer
How do I get logs from RDAC in
the Linux OS? Use the mppSupport command to obtain
several logs related to RDAC. The mppSupport
command is found in the /opt/mpp/mppSupport
directory. The command creates a file named
mppSupportdata_hostname_RDAC
version_datetime.tar.gz in the /tmp directory.

Question Answer
How does persistent naming
work? The Linux OS SCSI device names can change when the
host system restarts. Use a utility, such as devlabel, to
create user-defined device names that will map devices
based on a unique identifier. The udev method is the
preferred method for SLES 10 and RHEL.
What must I do after applying a
kernel update? After you apply the kernel update and start the new
kernel, perform these steps to build the RDAC Initial Ram
Disk image (initrd image) for the new kernel:
1. Change the directory to the Linux RDAC source code
directory.
2. Type make uninstall, and press Enter.
3. Reinstall RDAC.
What is the Initial Ram Disk
Image (initrd image), and how do
I create a new initrd image?
The initrd image is automatically created when the driver
is installed by using the make install command. The
boot loader configuration file must have an entry for this
newly created image.
The initrd image is located in the boot partition. The file is
named mpp‘-uname -r’.img.
For a driver update, if the system already has a previous
entry for RDAC, the system administrator must modify the
existing RDAC entry in the boot loader configuration file.
In most of the cases, no change is required if the kernel
version is the same.
To create a new initrd image, type mppUpdate, and press
Enter.
The old image file is overwritten with the new image file.
If third-party drivers are needed to be added to the
initrd image, change the /etc/sysconfig/ kernel
file (SUSE) with the third-party driver entries. Run the
mppUpdate command again to create a new initrd image.
How do I remove unmapped or
disconnected devices from the
existing host?
Run hot_add -d to remove all unmapped or
disconnected devices.
What if I remap a LUN from the
storage array? Run hot_add -u to update the host with the changed
LUN mapping.
What if I change the size of the
LUN on the storage array? Run hot_add -c to change the size of the LUN on the
host.
How do I make sure that RDAC
finds the available storage
arrays?
To make sure that the RDAC driver has found the
available storage arrays and created virtual storage arrays
for them, type these commands, and press Enter after
each command.
ls -lR /proc/mpp

Question Answer
What should I do if I receive this
message?
Warning: Changing the
storage array name can
cause host applications
to lose access to the
storage array if the host
is running certain path
failover drivers.
If any of your hosts are
running path failover
drivers, please update
the storage array name
in your path failover
driver’s configuration
file before rebooting the
host machine to insure
uninterrupted access to
the storage array. Refer
to your path failover
driver documentation for
more details.
The path failover drivers that cause this warning are the
RDAC drivers on both the Linux OS and the Windows OS.
The storage array user label is used for storage array-to-
virtual target ID binding in the RDAC driver. For the Linux
OS, change this file to add the storage array user label
and its virtual target ID.

Device Mapper Multipath for the Linux Operating System
Device Mapper (DM) is a generic framework for block devices provided by the Linux operating system. It
supports concatenation, striping, snapshots, mirroring, and multipathing. The multipath function is provided by
the combination of the kernel modules and user space tools.
The DMMP is supported on SUSE Linux Enterprise Server (SLES) Version 11. The SLES installation must
have components at or above the version levels shown in the following table before you install the DMMP.
Miimum Supported Configurations for the SLES 11 Operating System
Version Component
Kernel version kernel-default-2.6.27.29-0.1.1
Scsi_dh_rdac kmp lsi-scsi_dh_rdac-kmp-
default-0.0_2.6.27.19_5-1
Device Mapper library device-mapper-1.02.27-8.6
Multipath-tools multipath-tools-0.4.8-40.6.1
To update a component, download the appropriate package from the Novell website at http://
download.novell.com/patch/finder. The Novell publication, SUSE Linux Enterprise Server 11 Installation and
Administration Guide, describes how to install and upgrade the operating system.
Device Mapper Features
Provides a single block device node for a multipathed logical unit
Ensures that I/O is re-routed to available paths during a path failure
Ensures that the failed paths are revalidated as soon as possible
Configures the multipaths to maximize performance
Reconfigures the multipaths automatically when events occur
Provides DMMP features support to newly added logical unit
Provides device name persistency for DMMP devices under /dev/mapper/
Configures multipaths automatically at an early stage of rebooting to permit the OS to install and reboot
on a multipathed logical unit
Known Limitations and Issues of the Device Mapper
When storage is configured with AVT mode, delays in device discovery might occur. Delays in device
discovery might result in long delays when the operating system boots.
In certain error conditions with no_path_retry or queue_if_no_path feature set, applications might
hang forever. To overcome these conditions, you must enter the following command to all the affected
multipath devices: dmsetup message device 0 "fail_if_no_path", where device is the
multipath device name (for example, mpath2; do not specify the path).
An I/O hang might occur when a volume is unmapped without first deleting the DM device.
NOTE This limitation applies to only the SUSE 11 OS.
SANtricity_10.77 February 2011
LSI Corporation
- 942 -
Stale entries might not be noticed in multipath -ll output if the volumes are unmapped or deleted without
first deleting the DM device and its underlying paths.
NOTE This limitation applies to only the SUSE 11 OS.
Currently, the mode select command is issued synchronously for each LUN. With large LUN
configurations, slower failovers for DM multipath devices might occur if there is any delay in completing of
the mode select command.
NOTE This limitation applies to only the SUSE 11 OS.
If the scsi_dh_rdac module is not included in initrd, slower device discovery might occur, and the syslog
might get populated with buffer I/O error messages.
If the storage vendor and model are not included in scsi_dh_rdac device handler, slower device discovery
might be seen, and the syslog might get populated with buffer I/O error messages.
Use of the DMMP and RDAC failover solutions together on the same host is not supported. Use only one
solution at a time.
Installing the Device Mapper Multi-Path
1. Use the media supplied by your operating system vendor to install SLES 11.
2. Install the errata kernel 2.6.27.29-0.1.
Refer to the SUSE Linux Enterprise Server 11 Installation and Administration Guide for the installation
procedure.
3. To boot up to 2.6.27.29-0.1 kernel, reboot your system.
4. On the command line, enter rpm -qa |grep device-mapper, and check the system output to see if
the correct level of the device mapper component is installed.
The correct level of the device mapper component is installed – Go to step 5.
The correct level of the device mapper component is not installed – Install the correct level of
the device mapper component or update the existing component, and go to step 5.
5. On the command line, enter rpm -qa |grep multipath-tools, and check the system output to see
if the correct level of the multipath tools is installed.
The correct level of the multipath tools is installed – Go to step 6.
The correct level of the multipath tools is not installed – Install the correct level of the multipath tools
or update the existing multipath tools, and go to step 6.
6. Update the configuration file /etc/multipath.conf.
See Setting Up the multipath.conf File for detailed information about the /etc/multipath.conf file.
7. On the command line, enter chkconfig multipathd on.
This command enables multipathd daemon when the system boots.
8. Edit the /etc/sysconfig/kernel file to add directive scsi_dh_rdac to the INITRD_MODULES section
of the file.
9. Download the KMP package for scsi_dh_rdac for the SLES 11 architecture from the website http://
forgeftp.novell.com/driver-process/staging/pub/update/lsi/sle11/common/, and install the package on the
host.
10. Update the boot loader to point to the new initrd image, and reboot the host with the new initrd image.

Setting Up the multipath.conf File
The multipath.conf file is the configuration file for the multipath daemon, multipathd. The
multipath.conf file overwrites the built-in configuration table for multipathd. Any line in the file whose first
non-white-space character is # is considered a comment line. Empty lines are ignored.
Installing the Device Mapper Multi-Path for SLES 11.1
All of the components required for DMMP are included in SUSE Linux Enterprise Server (SLES) version
11.1 installation media. However, users might need to select the specific component based on the storage
hardware type. By default, DMMP is disabled in SLES. You must follow the following steps to enable DMMP
components on the host.
1. On the command line, type chkconfig multipath on.
The multipathd daemon is enabled with the system starts again.
2. Edit the /etc/sysconfig/kernel file to add the directive scsi_dh_rdac to the INITRD_MODULES
section of the file.
3. Create a new initrd image using the following command to include scsi_dh_rdac into ram disk:
mkinitrd -i /boot/initrd-r -rdac -k /bootvmlinuz
4. Update the boot leader to point to the new initrd image, and reboot the host with the new initrd image.
Copy and Rename the Sample File
Copy and rename the sample file located at /usr/share/doc/packages/multipath-tools/
multipath.conf.synthetic to /etc/multipath.conf. Configuration changes are now accomplished
by editing the new /etc/multipath.conf file. All entries for multipath devices are commented out initially.
The configuration file is divided into five sections:
defaults – Specifies all default values.
blacklist – All devices are blacklisted for new installations. The default blacklist is listed in the
commented-out section of the /etc/multipath.conf file. Blacklist the device mapper multipath by
WWID if you do not want to use this functionality.
blacklist_exceptions – Specifies any exceptions to the items specified in the section blacklist
devices – Lists all multipath devices with their matching vendor and product values
multipaths – Lists the multipath device with their matching WWID values
Determine the Attributes of a MultiPath Device
To determine the attributes of a multipath device, check the multipaths section of the /etc/
multipath.conf file, then the devices section, then the defaults section. The model settings used for
multipath devices are listed for each storage array and include matching vendor and product values. Add
matching storage vendor and product values for each type of volume used in your storage array.
For each UTM LUN mapped to the host, include an entry in the blacklist section of the /etc/
multipath.conf file. The entries should follow the pattern of the following example.
blacklist {
device {
vendor "*"
product "Universal Xport"
}

is disabled. Set this parameter to fail for
immediate failure (no queuing). When this
parameter is set to queue, queuing continues
indefinitely.
rr_min_io 100 The number of I/Os to route to a path before
switching to the next path in the same path
group. This setting applies if there is more
than one path in a path group.
Using the Device Mapper Devices
Multipath devices are created under /dev/ directory with the prefix dm-. These devices are the same as
any other bock devices on the host. To list all of the multipath devices, run the multipath –ll command.
The following example shows system output from the multipath –ll command for one of the multipath
devices.

Failover Drivers for the Solaris Operating System
MPxIO is the supported failover driver for the Solaris operating system.
Solaris OS Restrictions
SANtricity ES Storage Manager no longer supports or includes RDAC for these Solaris operating systems:
Solaris 10 OS
Solaris 9 OS
Solaris 8 OS
NOTE MPxIO is not included on the SANtricity ES Storage Manager Installation DVD.
Prerequisites for Installing MPxIO on the Solaris OS for the First Time
Perform these prerequisite tasks.
1. Install the hardware
2. Map the volumes.
3. Make sure that RDAC is not on the system, because you cannot run both RDAC and MPxIO.
IMPORTANT RDAC and MPxIO cannot run on the same system.
Prerequisites for Installing MPxIO on a Solaris OS That Previously Ran RDAC
Perform these prerequisite tasks:
1. Make sure that there are no major problems in the current RDAC.
ATTENTION Potential loss of data access – Some activities, such as adding and removing
storage arrays, can lead to stale information in the RDAC module name file. These activities might also
render data temporarily inaccessible.
2. To make sure that there are no leftover RDAC files, type this command, and press Enter:
ls -l /var/symsm/directory
3. To make sure that the RDAC directory does not exist, type this command, and press Enter:
ls -l /dev/rdsk/*s2 >>filename
4. Examine the /etc/symsm/mnf file. There should be one line for each currently connected storage array.
An example line is:
infiniti23/24~1T01610104~ 0 1 7~1T04110240~ 7~0~3~~c6t3d0~c4t2d7~
5. Make sure that there are no extra lines for disconnected storage arrays.
6. Make sure that two controllers are listed on each line. (The example shows c6t3 and c4t2.)
7. Make sure that these are the correct controllers.
SANtricity_10.77 February 2011
LSI Corporation
- 948 -
8. Make sure there are no identical cXtX combinations. For example, if you see c6t3d0 and c6t3d4, a
problem exists.
9. Make sure that no major problems exist in the Solaris OS.
When you reset or power-cycle a controller, it might take up to three minutes to come fully ready. Older
storage arrays might take longer. The default Solaris Not Ready retry timer is only 30 seconds long, so
spurious controller failovers might result. Sun Microsystems has already increased the timer for LSI-
branded storage arrays to two minutes.
10. Make sure that the VERITAS Volume Manager can handle the MPxIO upgrade.
11. Capture the current configuration by performing these steps:
a. Save this file.
/etc/symsm/mnf
b. Save this file.
/etc/raid/rdac_address
c. Type this command, and press Enter:
ls -l /dev/rdsk/*s2 >>rdsk.save
d. Type this command, and press Enter:
ls -l /dev/symsm/dev/rdsk/*s2 >>symsm.save
e. Type this command, and press Enter:
lad -y >>lad.save
12. To remove RDAC, type this command, and press Enter:
pkgrm RDAC
IMPORTANT Do not restart the system at this time.
Installing MPxIO on the Solaris 9 OS
MPxIO is not included in the Solaris 9 OS. To install MPxIO on the Solaris 9 OS, perform these steps.
1. Download and install the SAN 4.4x release Software/Firmware Upgrades and Documentation from this
website:
http://www.sun.com/storage/san/
2. Install recommended patches.
3. To enable MPxIO on the Solaris 9 OS, perform these steps:
a. Open this file:
/kernel/drv/scsi_vhci.conf
b. Change the last line in the script to this command:
mpxio-disable="no";
NOTE Make sure that "no" is enclosed in double quotation marks.
SANtricity_10.77 February 2011
LSI Corporation
- 949 -
4. Disable MPxIO on any Fibre Channel drives, such as internal drives, that should not be MPxIO enabled.
To disable MPxIO on specific drives, perform these steps:
a. Open the Fibre Channel port driver configuration file:
/kernel/drv/qlc.conf
b. Add a line similar to the following:
name="qlc" parent="/pci@8,600000" port=0 unit-address="2"
mpxio-disable="yes";
NOTE To find the correct parent and port numbers, look at the device entry for the internal
drives, found in /dev/dsk,
5. To update vfstab and the dump configuration, type this command:
stmsboot -u
6. Reboot the system.
Enabling MPxIO on the Solaris 10 OS
MPxIO is included in the Solaris 10 OS; therefore, it does not need to be installed. It only needs to be
enabled.
1. To enable MPxIO for all Fibre Channel drives, enter the command:
stmsboot -e
2. If there are any Fibre Channel drives for which you do not want MPxIO enabled, for example, internal
drives, disable MPxIO on those drives. To disable MPxIO on specific drives, perform these steps:
a. Edit the Fibre Channel port driver configuration file /kernel/drv/fp.conf.
b. Add a line similar to the following:
name="fp" parent="/pci@8,600000/SUNW,qlc@2" port=0
mpxio-disable="yes";
To find the correct parent and port numbers, look at the device entry for the internal drives, found in /
dev/dsk.
3. To update vfstab and the dump configuration, enter the command:
stmsboot -u
4. Reboot the system.
Configuring Failover Drivers for the Solaris OS
ATTENTION Possible loss of data – Create a backup of your configuration before you change any
configuration file.
Configure the host settings for these parameters in the /etc/ system file.
ssd_io_time – Add the line set ssd:ssd_io_time=0x78 to the system file.
ssd_max_throttle – Add the line set ssd:ssd_max_throttle=8 to the system file.
SANtricity_10.77 February 2011

Configure MPxIO multi-pathing in the /kernel/drv/scsi_vhci.conf file with these recommended
parameters.
mpxio-disable – Set to no.
load-balance – Set to none.
IMPORTANT For a symmetric storage array, you must specify round-robin so that the driver can
balance the I/O load between the two paths.
auto-failback – Set to enable.
To add a device, add these lines to the end of the scsi_vhci.conf file:
device-type-scsi-options-list="Acme MSU",
"symmetric-option";symmetric-option=0x1000000;
where Acme is the vendor ID, and MSU is the product ID.
IMPORTANT Make sure five spaces exist between the vendor ID and the product ID.

How can I get a list of
controllers and their volumes? Use the lad -y command. The command uses LUN 0
to get the information and is located in the /usr/lib/
symsm/bin directory. It can be reached through /etc/
raid/bin. This command updates the mnf file.

LSI Corporation
- 951 -
Question Answer
Where can I get a list of storage
arrays, their volumes, LUNs,
WWPNs, preferred paths, and
owning controller?
Use the SMdevices utility.
This utility must be in the search path and is located in the /
opt/SM7util directory or the /opt/SM8/util directory.
How can I see if volumes have
been added? Use the hot_add utility. This utility asks the Solaris OS
target drivers to find new devices.
The hot_add utility works only after all of the potential
devnodes have been created in the OS. If not, run the
devfsadm command, and run the hot_add utility. If these
actions do not work, restart with the reconfiguration option.
What file holds the storage
array identification information? Go to the /etc/[osa|symsm]/mnf directory. The mnf
file identifies storage arrays in these ways:
Lists their ASCII names
Shows their controller serial numbers
Indicates the current LUN distribution
Lists controller system names
Lists the storage array numbers
Why might the rdriver fail to
attach and what can I do about
it?
The rdriver might not attach if there is no entry in the
rdriver.conf file to match the device, or if rdnexus runs
out of buses.
If no physical devnode exists:
The sd.conf file must specify LUNs explicitly.
The ssd.conf file with the itmpt HBA must specify
LUNs explicitly.
With Sun driver stacks, underlying HBA drivers
dynamically create devnodes for ssd.
You must restart the system with the reconfigure option
after you update the rdriver.conf file.
In the Solaris 9 OS, you can use the update_drv
command if the HBA driver supports it.
How can I determine if the
resolution daemon is working? Type this command, and press Enter:

14. If you determined from the storage array profile that the NVSRAM firmware, the controller firmware, or the
ESM firmware is not the current version, download the compatible firmware.
NOTE You can upgrade from RAID Core 1 to RAID Core 2, by using the Enterprise Management
Window. See “Upgrading the Firmware and the NVSRAM.”
Software Packages
All SANtricity ES Storage Manager software packages are generally installed in the same directory on the
same system, whether the system is a host or a separate storage management station.
SANtricity ES Storage Manager Software Packages
Software Package Description and Usage
SMclient This package contains the graphical user interface for
managing the storage array. This package also contains
an optional monitor service that sends alerts when a critical
problem exists with the storage array.
SMagent The storage management software that is installed only on a
host system to enable in-band management.*
SMruntime The operating system (OS) -specific storage management

* In-band management is a method for managing a storage array in which the controllers
are managed from a storage management station attached to a host that is running
host-agent software. The host-agent software receives communication from the storage
management client software and passes it to the storage array controllers along a Fibre
Channel input/output (I/O) path. The controllers also use the I/O connections to send
event information back to the storage management station through the host.
NOTE The Microsoft Virtual Disk Service (VDS) and Volume Shadow Copy Service (VSS) providers
are a part of the SANtricity ES Storage Manager package for the Windows Server 2003 OS and the Windows
Server 2008 OS.

Converting a Controller-Drive Tray to a Drive Tray and Adding a Controller
Tray
You can upgrade the storage array by converting the controller-drive tray to a drive tray and adding a
controller tray. Contact your Customer and Technical Support representative to order a tray conversion kit.
Refer to the tray conversion kit instructions for complete instructions about how to convert a controller-drive
tray to a drive tray. Use this procedure to add a new controller tray to your storage array.
NOTE If you are adding a new controller tray that has controllers running controller firmware version
7.10 or later, the controllers in your original storage array must also be running controller firmware version
7.10 or later.
Also, make sure that you can connect the tray and the drives to the new controller. For example, you cannot
connect a DM1300 drive tray to a CE6998 controller tray or a CE7900 controller tray.
NOTE Before starting this procedure, make sure that you have the removal and replacement procedure
instructions for the environmental services monitors (ESMs). For older hardware models, this documentation
is not included in documentation delivered with the current release of SANtricity ES Storage Manager.
1. Stop I/O, and turn off the power to the controller-drive tray and the drive trays.
2. Disconnect the host cables from the controllers.
3. If the storage array has drive trays connected to the controller-drive tray, disconnect the cables from the
controllers to the ESMs in the drive trays.
4. Remove the controllers from the controller-drive tray.
5. Insert the ESMs into the controller-drive tray to replace the controllers.
6. Connect the cables from the ESMs in the other drive trays to the new ESMs.
If the drive cable is connected to port 1 of the drive tray, connect the other end of the cable to port 2
of the new ESM.
If the drive cable is connected to port 2 of the drive tray, connect the other end of the cable to port 1
of the new ESM.
For a complete description of the various cabling options, refer to the topics under Hardware Cabling or to
the SANtricity ES Storage Manager Installation DVD for the corresponding PDF document.
NOTE Make sure that you have enough space in the cabinet for the new controller tray before you
perform the next step.
7. Insert the new controller tray into the cabinet. Refer to the topics under Installation for the controller tray
that you have chosen to upgrade for more details about how to secure the controller tray to the cabinet.

Upgrading the Firmware and the NVSRAM
You can upgrade the firmware of the controllers and the NVSRAM in the storage array by using the storage
management software.
In the process of upgrading the firmware, the firmware file is downloaded from the host to the controller.
After downloading the firmware file, you can upgrade the controllers in the storage array to the new firmware
immediately. Optionally, you can download the firmware file to the controller and upgrade the firmware later at
a more convenient time.
Activating the Firmware
The process of upgrading the firmware after downloading the firmware file is known as activation. During
activation, the existing firmware file in the memory of the controller is replaced with the new firmware file.
You might want to activate the firmware or NVSRAM files at a later time because of the following reasons:
Time of day – Activating the firmware and the NVSRAM can take a long time, so you might want to wait
until I/O loads are lighter. The controllers will go offline briefly to load the new firmware.
Type of package – You might want to test the new firmware on one storage array before upgrading the
firmware in other storage arrays.
The firmware upgrade process requires that the controllers have enough free memory space in which the
firmware file resides until activation.
Firmware Version
A version number exists for each firmware file. For example, 06.60.08.00 is a version number for a firmware
file. The first two digits indicate the major revision of the firmware file. The remaining digits indicate the minor
revision of the firmware file. You can view the version number of a firmware file in the Upgrade Controller
Firmware window and the Download Firmware dialog.
The process of upgrading the firmware can be either a major upgrade or a minor upgrade depending on the
version of the firmware.
For example, the process of upgrading the firmware is major if the version of the current firmware is
06.60.08.00, and you want to upgrade the firmware to version 07.36.12.00. In this example, the first two digits
of the version numbers are different and indicate a major upgrade. In a minor upgrade, the first two digits
of the version numbers are the same. For example, the process of upgrading the firmware is minor, if the
version of the current firmware is 06.60.08.00, and you want to upgrade the firmware to version 06.60.18.00,
or any other minor revision of the firmware.
IMPORTANT The firmware versions from 05.xx.xx.xx through 06.12.xx.xx are versions before the
RAIDCore1. The firmware versions from 06.14.xx.xx through 06.60.xx.xx are RAIDCore1. The firmware
version starting from 07.xx.xx.xx are RAIDCore2.
You can use the Enterprise Management Window to perform both major upgrades and minor upgrades.
You can use the Enterprise Management Window to perform a major upgrade from firmware version number
05.40.xx.xx to any later version, such as 06.xx.xx.xx, and 07.xx.xx.xx, where xx represent the digits that
indicate the minor revision of the firmware.
You can use the Array Management Window to perform minor upgrades only.

The storage management software checks for existing conditions in the storage array before upgrading the
firmware. Any of these conditions in the storage array can prevent the firmware upgrade:
An unsupported controller type or controllers of different types that are in the storage array and cannot be
upgraded
One or more failed drives
One or more hot spare drives that are in use
Two or more volume groups that are incomplete
Operations, such as defragmenting a volume group, downloading of drive firmware, and others that are in
progress
Missing volumes that are in the storage array
Controllers that have a status other than Optimal
The storage partitioning database is corrupt
A data validation error occurred in the storage array
The storage array is in the Needs Attention status
The storage array is unresponsive, and the storage management software cannot communicate with the
storage array
The Event Log entries are not cleared
For more information on downloading the firmware and NVSRAM, refer to the online help topics in SANtricity
ES Storage Manager.
You can correct some of these conditions by using the Array Management Window. However, for some of
the conditions, you might need to contact your Customer and Technical Support representative. The storage
management software saves the information about the firmware upgrade process in log files. This action
helps the Customer and Technical Support representative to understand the conditions that prevented the
firmware upgrade.
You also can use the command line interface (CLI) to download and activate firmware to several storage
arrays. For more information, refer to the online help topics in SANtricity ES Storage Manager.

Upgrading from Limited High Availability (LHA) to Full High
Availability (FHA)
You can upgrade the environmental services monitors (ESMs) in the drive trays from LHA ESMs to FHA
ESMs by using SANtricity ES Storage Manager. The following sections describe the procedure for upgrading
from an LHA ESM to an FHA ESM.
Terms Applicable to LHA and FHA
Terms Applicable to LHA and FHA
Term Definition
LHA Limited high availability, also known as dSATA Phase 1. This specification
refers to each ESM that retains sole ownership of seven drives per drive
tray, without full failover capacity.
FHA Full high availability, also known as dSATA Phase 2. This specification
refers to each ESM that retains ownership of seven drives per drive tray.
The first version of FHA consists of firmware version level 9550 and
controller firmware level 05.41.50.xx. Anything prior to this version is LHA.
*.dl A download file in package format for the ESM.
This file contains header information and package
information. This file can contain more than one type
of firmware packaged to download together. This file
is downloadable through the storage management
software. This file is not downloadable serially.
*.s3r A raw “S” record file without header information and
wrapper information that is not downloadable through
the storage management software.
*.dlf A raw firmware file without header information and
wrapper information that is not downloadable through
the storage management software. The *.dlf file
is packaged into a *.dl file, and the *.dlf file is
downloadable serially.
*.dlp A download file in package format for the controller
firmware. This file contains header information and
package information, and it is downloadable through
the storage management software.
Controller
firmware Controller firmware for the controllers in the storage
array. The firmware is downloadable through the
storage management software.

The CSB file (csb_xxx_xxxx.dl1).* The file is
downloadable through the storage management
software.
noReboot ESM firmware downgrade from FHA to LHA versions is wrapped in
this format (esm95xx_noReboot.dl). After the firmware completes
its download, it does not reboot the ESM to start running on the newly
downloaded firmware code. In this case, you must manually reboot the ESM
by cycling the power.
* The xxx noted in the CSB file name indicates an OEM-specific identifier.
ATTENTION Possible loss of data access – Downloading a customer-specific behavior (CSB) file
with a non-matching shared secret results in the loss of data on the drive.
Upgrading an LHA ESM to an FHA ESM
Use this procedure to check the current firmware versions and to download the ESM firmware, the full high
availability customer-specific behavior (FHA CSB) file, and the controller firmware. This procedure describes
the LHA-to-FHA upgrade only. Perform this procedure only if your controller firmware version is 05.41.12.00
or earlier.
FHA controller firmware versions have implemented a “lockout” mechanism to prohibit downloading firmware
to drive trays that contain LHA ESMs. This mechanism was implemented because the LHA controller
firmware stops all I/O, which includes background DACstore and data scrubbing I/O, during an ESM
download.
With FHA controller firmware, the I/O is no longer stopped during an ESM download, because the ESM can
fail over the I/O to the other ESM. The lockout mechanism prevents users from starting a download to an LHA
ESM, which cannot perform a failover.
Before you begin this procedure, verify these items:
Make sure that your hardware is compatible with the software levels and the firmware levels to which you
want to upgrade. Check the supported host bus adapters (HBAs), switches, tested driver levels, tested
firmware levels, and specific hardware restrictions.
Make sure that SANtricity ES Storage Manager Version 10.75 is installed and operating on your storage
array.

NOTE Perform the steps of the procedure in order so that you download all FHA CSB and ESM
firmware packages before you upgrade the FHA controller firmware.
ATTENTION Possible I/O failure and loss of data – Before you start the download process, suspend
all I/O activity. If you do not suspend all I/O activity, I/O failure, data loss, and other serious problems could
result.
1. Stop all I/O activity and background operations. You must stop the controller before downloading the
firmware.

storage array that you want to assign as a boot device must have dual controllers connected to two host
bus adapters (HBAs). If the storage array has a single controller or dual controllers that are connected to the
same HBA (host path), you do not have failover protection and could lose access to the boot device when the
controller fails or has connection problems. For this reason, do not use this type of controller configuration
with a boot device installation.
You must have administrator privileges to access the software. You must use the volume mapped to LUN 0
as the boot device. Some operating systems support booting only from LUN 0.

Before you proceed with the installation, make sure that you have installed SMclient from the SANtricity ES
Storage Manager software in a host or a storage management station that is attached to the storage array.
IMPORTANT Before you complete the installation of the storage management software components in
the host, perform the tasks in this section to install and configure of the storage array and the host to use the
storage array as a boot device. If you have questions or concerns about the installation procedures, contact
your Customer and Technical Support representative.
IMPORTANT On Itanium 64-bit hosts, the storage array can be successfully used as a boot device, but
only when the original, local boot disk remains in the host system. Do not remove the local disk from the host
system, or you will not be able to boot from the storage array.
Perform the following tasks in the order shown:
1. "Starting the Client Software"
2. "Configuring the Boot Volume on the Storage Array"

12. Go to “Ensuring a Single Path to the Storage Array.”
Ensuring a Single Path to the Storage Array
After you have configured a boot volume, make sure that only one path to the storage array exists. The path
must be configured to the controller that owns the boot volume (controller A).
NOTE If you removed a previously installed version of RDAC in a root-boot environment, you do not
need to remove the installed version of RDAC again.
1. Choose one of two methods to make sure that the alternate path to the storage array is removed:
Method 1 – Remove the host interface cable to the alternate path. Go to step 3.
Method 2 – Modify NVSRAM to temporarily disable RDAC multi-path functionality in the storage
array. Go to step 2.
2. Modify NVSRAM to temporarily disable RDAC multi-path functionality by performing these substeps:
a. Select the storage array in the Enterprise Management Window.
b. Select Tools >> Execute Script.
The Script Editor dialog appears.
c. In the upper half of the Script Editor dialog, type these commands at the prompt, and press Enter.
set controller[a] HostNVSRAMByte[1,0x16]=0xFF,0x20;
set controller[b] HostNVSRAMByte[1,0x16]=0xFF,0x20;
d. Select Tools >> Execute Only.
e. For the NVSRAM modifications to take effect, turn off the power to the controller tray, wait 30
seconds for the controller tray to turn off the power, and turn on the power again.
ATTENTION Possible data corruption – Only one path to the storage array must exist
when RDAC is removed. The path must be to the controller that owns the boot volume. If the host is
permitted to start without RDAC and still has dual paths to the storage array, the data might become
unusable.
3. Boot the host system.
4. Go to “Preparing the Host.”
SANtricity_10.77 February 2011
LSI Corporation
- 991 -
Preparing the Host
ATTENTION Possible loss of access to the boot device and the operating system – After you
install the boot device, do not delete the volume mapped to LUN 0 or reset the configuration. Performing
these actions causes loss of access to the boot device and the operating system.
In this procedure, the default boot path refers to controller A, which owns the boot volume. The alternate boot
path refers to controller B.
1. Enable the BIOS on the HBA that is connected to the default boot path.
For procedures about how to enable the HBA BIOS, refer to the host system documentation and the HBA
documentation. After the BIOS is enabled, the host reboots automatically.
2. Make sure that the HBA with enabled BIOS is connected to the default boot path (controller A), and the
HBA with disabled BIOS is connected to the alternate boot path (controller B).
3. Install the operating system on the host.
4. After the installation is complete, restart the operating system.
5. To enable the alternate path to the storage array, go to step 2 in “Completing the Installation Process.”
Completing the Installation Process
This procedure completes the root-boot environment setup. Use this procedure to restart the system or set
the path for the command line interface (CLI), if necessary.
1. Do you want to install the software in a root-boot environment?
Yes – Go to step 2.
No – Go to step 5.
2. Based on the method that you used to disable the alternate path in step 1 in “Ensuring a Single Path to
the Storage Array,“ perform one of these actions to enable the alternate path to the storage array:
You removed the host interface cable to the storage array – Reattach the host interface cable to
the alternate controller. Go to step 5.
You modified NVSRAM to temporarily disable RDAC multi-path functionality in the storage
array – Go to step 3.
3. Will you download new controller firmware and NVSRAM to the storage array after the host software
installation?
Yes – The new NVSRAM file is pre-configured to enable RDAC multi-path functionality. Go to step 5.
No – Go to step 4.
4. Open the command prompt window, and perform these substeps:
a. Type these commands, and press Enter.
“set controller[a] HostNVSRAMByte[1,0x16]=0xFF,0x20;”
“set controller[b] HostNVSRAMByte[1,0x16]=0xFF,0x20;”
b. For the NVSRAM modifications to take effect, turn off the power to the controllers, wait 30 seconds
for the controllers to power down, and turn on the power.
5. Restart the host system.

d. Select the Path entry, and click Edit in the System variables area of the Environment Variables
dialog.
e. In the Variable Value text box of the Edit System Variable dialog, type this command at the end of
the current value, and press Enter. In this command, <path> is the path to the SMclient installation
directory.
<path>
For example:
%SystemRoot%\system32;%SystemRoot%;C:\ProgramFiles\StorageManager\client;
f. Click OK. In the next dialog, click OK.
8. Based on your installation environment, perform one of these actions:
You are using a cluster environment – Go to step 9.
You are using a standard environment – Go to step 10.
9. Install the host software on each host in the server cluster.
IMPORTANT Do not configure the server cluster software at this time. You are instructed when to
configure the server cluster software after you complete the storage management software installation.
You cannot mix two architectures in the same server cluster. For example, a server cluster cannot contain
both the 32-bit version and the 64-bit version of the Windows OS.
10. Start the SANtricity ES Storage Manager software with the procedure for your operating system.
After the client software starts, the Enterprise Management Window appears.

Command Line Interface and Script Commands for
Version 10.77
This document provides a complete listing of all of the commands and the syntax for those commands that
you need to configure and maintain a storage array. Information about how to configure and maintain a
storage array using a command line interface is in Configuring and Maintaining a Storage Array using the
Command Line Interface
This document supports host software version 10.77 and firmware version 7.77.
SANtricity_10.77 February 2011
LSI Corporation
- 994 -
Formatting the Commands
The command line interface (CLI) is a software application that provides a way to configure and monitor
storage arrays. Using the CLI, you can run commands from an operating system prompt, such as the DOS C:
prompt, a Linux operating system path, or a Solaris operating system path.
The CLI gives you direct access to a script engine that is a utility in the SANtricity ES Storage Manager
software (also referred to as the storage management software). The script engine runs commands that
configure and manage the storage arrays. The script engine reads the commands, or runs a script file, from
the command line and performs the operations instructed by the commands.
The script commands configure and manage a storage array. The script commands are distinct from the CLI
commands. You can enter individual script commands, or you can run a file of script commands. When you
enter an individual script command, you embed the script command in a CLI command. When you run a file
of script commands, you embed the file name in the CLI command.
Structure of a CLI Command
The CLI commands are in the form of a command wrapper and elements embedded into the wrapper. A CLI
command consists of these elements:
A command wrapper identified by the term SMcli
The storage array identifier
Terminals that define the operation to be performed
Script commands
The CLI command wrapper is a shell that identifies storage array controllers, embeds operational terminals,
embeds script commands, and passes these values to the script engine.
All CLI commands have the following structure:
SMcli storageArray terminal script-commands;
SMcli invokes the command line interface.
storageArray is the name or the IP address of the storage array.
terminal are CLI values that define the environment and the purpose for the command.
script-commands are one or more script commands or the name of a script file that contains script
commands. (The script commands configure and manage the storage array.)
If you enter an incomplete or inaccurate SMcli string that does not have the correct syntax, parameter
names, options, or terminals, the script engine returns usage information.
For an overview of the script commands, see "." For definitions, syntax, and parameters for the script
commands, refer to the Command Line Interface and Script Commands for Version 10.75.
Interactive Mode
If you enter SMcli and a storage array name but do not specify CLI parameters, script commands, or a script
file, the command line interface runs in interactive mode. Interactive mode lets you run individual commands
without prefixing the commands with SMcli.
SANtricity_10.77 February 2011
LSI Corporation
- 995 -
In interactive mode, you can enter a single command, view the results, and enter the next command without
typing the complete SMcli string. Interactive mode is useful for determining configuration errors and quickly
testing configuration changes.
To end an interactive mode session, type the operating system-specific command for terminating a program,
such as Control-C on the UNIX operating system or the Windows operating system. Typing the termination
command (Control-C) while in interactive mode turns off interactive mode and returns operation of the
command prompt to an input mode that requires you to type the complete SMcli string.
CLI Command Wrapper Syntax
General syntax forms of the CLI command wrappers are listed in this section. The general syntax forms show
the terminals and the parameters that are used in each command wrapper. The conventions used in the CLI
command wrapper syntax are listed in the following table.
Convention Definition

Command Line Terminals
Terminal Definition
host-name-or-
IP-address
Specifies either the host name or the Internet Protocol (IP) address
(xxx.xxx.xxx.xxx) of an in-band managed storage array or an
out-of-band managed storage array.
If you are managing a storage array by using a host through in-
band storage management, you must use the -n terminal or
the -w terminal if more than one storage array is connected to
the host.
If you are managing a storage array by using out-of-band
storage management through the Ethernet connection on each
controller, you must specify the host-name-or-IP-address
of the controllers.
If you have previously configured a storage array in the
Enterprise Management Window, you can specify the storage
array by its user-supplied name by using the -n terminal.
If you have previously configured a storage array in the
Enterprise Management Window, you can specify the storage
array by its World Wide Identifier (WWID) by using the -w
terminal.
-A Adds a storage array to the configuration file. If you do not follow
the -A terminal with a host-name-or-IP-address, auto-
discovery scans the local subnet for storage arrays.
-a Adds a Simple Network Management Protocol (SNMP) trap
destination or an email address alert destination.
When you add an SNMP trap destination, the SNMP
community is automatically defined as the community name
for the trap, and the host is the IP address or Domain Name
Server (DNS) host name of the system to which the trap should
be sent.
SANtricity_10.77 February 2011
LSI Corporation
- 997 -
Terminal Definition
When you add an email address for an alert destination, the
email-address is the email address to which you want the
alert message to be sent.
-c Indicates that you are entering one or more script commands to
run on the specified storage array. End each command with a
semicolon (;). You cannot place more than one -c terminal on
the same command line. You can include more than one script
command after the -c terminal.
-d Shows the contents of the script configuration file. The file content
has this format:
storage-system-name host-name1 host-name2
-e Runs the commands without performing a syntax check first.
-F (uppercase) Specifies the email address from which all alerts will be sent.
-f (lowercase) Specifies a file name that contains script commands that you want
to run on the specified storage array. The -f terminal is similar to
the -c terminal in that both terminals are intended for running script
commands. The -c terminal runs individual script commands. The
-f terminal runs a file of script commands.
By default, any errors that are encountered when running the
script commands in a file are ignored, and the file continues
to run. To override this behavior, use the set session
errorAction=stop command in the script file.
-g Specifies an ASCII file that contains email sender contact
information that will be included in all email alert notifications.
The CLI assumes that the ASCII file is text only, without
delimiters or any expected format. Do not use the -g terminal if a
userdata.txt file exists.
-h Specifies the host name that is running the SNMP agent to which
the storage array is connected. Use the -h terminal with these
terminals:
-a
-x
-I (uppercase) Specifies the type of information to be included in the email alert
notifications. You can select these values:
eventOnly – Only the event information is included in the
email.
profile – The event and array profile information is included
in the email.
supportBundle – The event and support bundle information
information is included in the email.
You can specify the frequency for the email deliveries using the -q
terminal.
SANtricity_10.77 February 2011
LSI Corporation
- 998 -
Terminal Definition
-i (lowercase) Shows the IP address of the known storage arrays. Use the -i
terminal with the -d terminal. The file contents has this format:
storage-system-name IP-address1 IPaddress2
-m Specifies the host name or the IP address of the email server from
which email alert notifications are sent.
-n Specifies the name of the storage array on which you want to run
the script commands. This name is optional when you use a host-
name-or-IP#address. If you are using the in-band method for
managing the storage array, you must use the -n terminal if more
than one storage array is connected to the host at the specified
address. The storage array name is required when the host-
name-or-IP-address is not used. The name of the storage array
that is configured for use in the Enterprise Management Window
(that is, the name is listed in the configuration file) must not be a
duplicate name of any other configured storage array.
-o Specifies a file name for all output text that is a result of running the
script commands. Use the -o terminal with these terminals:
-c
-f
If you do not specify an output file, the output text goes to standard
output (stdout). All output from commands that are not script
commands is sent to stdout, regardless of whether this terminal is
set.
-p Specifies the password for the storage array on which you want
to run commands. A password is not necessary under these
conditions:
A password has not been set on the storage array.
The password is specified in a script file that you are running.
You specify the password by using the -c terminal and this
command:
set session password=password
-q Specifies the frequency that you want to receive event notifications
and the type of information returned in the event notifications.
An email alert notification containing at least the basic event
information is always generated for every critical event.
These values are valid for the -q terminal:
everyEvent – Information is returned with every email alert
notification.
2 – Information is returned no more than once every two hours.
4 – Information is returned no more than once every four hours.
8 – Information is returned no more than once every eight
hours.
12 – Information is returned no more than once every 12 hours.
SANtricity_10.77 February 2011
LSI Corporation
- 999 -
Terminal Definition
24 – Information is returned no more than once every 24 hours.
Using the -I terminal you can specify the type of information in the
email alert notifications.
If you set the -I terminal to eventOnly, the only valid value
for the -q terminal is everyEvent.
If you set the -I terminal to either the profile value or the
supportBundle value, this information is included with the
emails with the frequency specified by the -q terminal.
-quick Reduces the amount of time that is required to run a single-line
operation. An example of a single-line operation is the recreate
snapshot volume command. This terminal reduces time by not
running background processes for the duration of the command.
Do not use this terminal for operations that involve more than
one single-line operation. Extensive use of this command can
overrun the controller with more commands than the controller can
process, which causes operational failure. Also, status updates and
configuration updates that are collected usually from background
processes will not be available to the CLI. This terminal causes
operations that depend on background information to fail.
-S (uppercase) Suppresses informational messages describing the command
progress that appear when you run script commands. (Suppressing
informational messages is also called silent mode.) This terminal
suppresses these messages:
Performing syntax check
Syntax check complete
Executing script
Script execution complete
SMcli completed successfully
-s (lowercase) Shows the alert settings in the configuration file when used with the
-d terminal.
-v Shows the current global status of the known devices in a
configuration file when used with the -d terminal.
-w Specifies the WWID of the storage array. This terminal is an
alternate to the -n terminal. Use the -w terminal with the -d
terminal to show the WWIDs of the known storage arrays. The file
content has this format:
storage-system-name world-wide-ID IP-address1 IP-
address2
-X (uppercase) Deletes a storage array from a configuration.
-x (lowercase) Removes an SNMP trap destination or an email address alert
destination. The community is the SNMP community name for
the trap, and the host is the IP address or DNS host name of the
system to which you want the trap sent.

Structure of a Script Command
All script commands have the following structure:
command operand-data (statement-data)
command identifies the action to be performed.
operand-data represents the objects associated with a storage array that you want to configure or
manage.
statement-data provides the information needed to perform the command.
The syntax for operand-data has the following structure:
(object-type | allobject-types | [qualifier]
(object-type [identifier] {object-type [identifier]} |
object-types [identifier-list]))
An object can be identified in four ways:
Object type – Use when the command is not referencing a specific object.
all parameter prefix – Use when the command is referencing all of the objects of the specified type in
the storage array (for example, allVolumes).
Square brackets – Use when performing a command on a specific object to identify the object (for
example, volume [engineering]).
A list of identifiers – Use to specify a subset of objects. Enclose the object identifiers in square brackets
(for example, volumes [sales engineering marketing]).
A qualifier is required if you want to include additional information to describe the objects.
The object type and the identifiers that are associated with each object type are listed in this table.

Because you can use the script commands to define and manage the different aspects of a storage array
(such as host topology, drive configuration, controller configuration, volume definitions, and volume group
definitions), the actual number of commands is extensive. The commands, however, fall into general
categories that are reused when you apply the commands to the different to configure or maintain a storage
array. The following table lists the general form of the script commands and a definition of each command.
General Form of the Script Commands
Syntax Description
activate object
{statement-data}
Sets up the environment so that an operation
can take place or performs the operation if the
environment is already set up correctly.
autoConfigure storageArray
{statement-data}
Automatically creates a configuration that is
based on the parameters that are specified in the
command.

suspended operation, and it continues from the
point where it was suspended.
Recurring Syntax Elements
Recurring syntax elements are a general category of parameters and options that you can use in the script
commands. The Recurring Syntax Elements table lists the recurring syntax parameters and the values that
you can use with the recurring syntax parameters. The conventions used in the recurring syntax elements are
listed in the following table.
Convention Definition

1For tray loss protection to work, each drive in a volume group must be in a separate tray. If you set the
trayLossProtect parameter to TRUE and you have selected more than one drive from any one tray, the
storage array returns an error. If you set trayLossProtect parameter to FALSE, the storage array performs
operations, but the volume group that you create might not have tray loss protection.
If you set the trayLossProtect parameter to TRUE, the storage array returns an error if the controller
firmware cannot find drives that will enable the new volume group to have tray loss protection. If you set the
trayLossProtect parameter to FALSE, the storage array performs the operation even if it means that the
volume group might not have tray loss protection.
2In trays that have drawers for holding the drives, drawer loss protection determines whether data on
a volume is accessible or inaccessible if a drawer fails. To help make sure that your data is accessible,
set the drawerLossProtect parameter to TRUE. For drawer loss protection to work, each drive in a
volume group must be in separate drawers. If you have a storage array configuration in which a volume
group spans several trays, you must make sure that the setting for drawer loss protection works with the
setting for tray loss protection. If you set the trayLossProtect parameter to TRUE, you must set the
drawerLossProtect parameter to TRUE. If you set the trayLossProtect parameter to TRUE, and
you set the drawerLossProtect parameter to FALSE, the storage array returns an error message and a
storage array configuration will not be created.
3To determine if a free capacity area exists, run the show volumeGroup command.
4The default drive (drive type) is fibre (Fibre Channel).
The driveType parameter is not required if only one type of drive is in the storage array. If you use the
driveType parameter, you also must use the hotSpareCount parameter and the volumeGroupWidth
parameter. If you do not use the driveType parameter, the configuration defaults to Fibre Channel drives.
5The dataAssurance parameter applies to the drives in a volume group. Using the dataAssurance
parameter, you can specify that protected drives must be selected for a volume group. If you want to set
the dataAssurance parameter to enabled, all of the drives in the volume group must be capable of data
assurance. You cannot have a mix of drives that are capable of data assurance and drives that are not
capable of data assurance in the volume group.
6The volumesPerGroupCount parameter is the number of equal-capacity volumes per volume group.
7The securityType parameter enables you to specify the security setting for a volume group that you are
creating. All of the volumes are also set to the security setting that you choose. Available options for setting
the security setting include:
none – The volume group is not secure.
SANtricity_10.77 February 2011
LSI Corporation
- 1010 -
capable – The volume group is security capable, but security has not been enabled.
enabled – The volume group is security enabled.
NOTE A storage array security key must already be created for the storage array if you want to set
securityType=enabled. (To create a storage array security key, use the create storageArray
securityKey command).
Naming Conventions
Names can have a maximum of 30 characters.
You can use any combination of alphanumeric characters, hyphens, and underscores for the names of
the following components:
Storage arrays
Host groups
Hosts
Volume groups
Volumes
HBA host ports
You must use unique names. If you do not use unique names, the controller firmware returns an error.
If the name contains more than one word, hyphens, or underscores, enclose the name in double
quotation marks (“ ”). In some usages, you must also surround the name with square brackets ([ ]). The
description of each parameter indicates whether you need to enclose a parameter in double quotation
marks, square brackets, or both.
The name character string cannot contain a new line.
On Windows operating systems, you must enclose the name between two back slashes (\\) in addition
to other delimiters. For example, the following name is used in a command that runs under a Windows
operating system:
[\“Engineering\”]
For a UNIX operating system and, when used in a script file, the name appears as in the following
example:
[“Engineering”]
When you enter a World Wide Identifier (WWID) of an HBA host port, some usages require that you
surround the WWID with double quotation marks. In other uses, you must surround the WWID with angle
brackets (<>). The description of the WWID parameter indicates whether you need to enclose the WWID
in double quotation marks or angle brackets.
Entering Numerical Names
When the storage management software automatically configures a storage array, the storage management
software assigns names that consist of numerical characters. Names that consist only of numerical characters
are valid names. Numerical character names, however, must be treated differently than names that start with
alphabetic characters.
When you enter a script command that requires a name, the script engine looks for a name that starts with an
alphabetic character. The Script Engine might not recognize the following names:
Names that are only numbers, such as 1 or 2
SANtricity_10.77 February 2011
LSI Corporation
- 1011 -
Names that start with a number, such as 1Disk or 32Volume
To enter a name that consists only of numerical characters so that the Script Engine will recognize the name,
use a combination of back slashes and double quotation marks. The following are examples of how you can
enter names that consist only of numerical characters or start with numerical characters:
[\“1\”]
[\“1Disk\”]
Formatting CLI Commands
Double quotation marks (" ") that are used as part of a name or label require special consideration when you
run the CLI commands and the script commands on a Microsoft Windows operating system.
When double quotation marks (" ") are part of a name or value, you must insert a backslash (\) before each
double quotation mark character. For example:
-c "set storageArray userLabel=\"Engineering\";"
In this example, "Engineering" is the storage array name. A second example is:
-n \"My\"_Array
In this example, "My"_Array is the name of the storage array.
You cannot use double quotation marks (" ") as part of a character string (also called string literal) within
a script command. For example, you cannot enter the following string to set the storage array name to
"Finance" Array:
-c "set storageArray userLabel=\"\"Finance\"Array\";"
In the Linux operating system and the Solaris operating system, the delimiters around names or labels are
single quotation marks (' '). The UNIX versions of the previous examples are as follows:
-c 'set storageArray userLabel="Engineering";'
-n "My"_Array
In a Windows operating system, if you do not use double quotation marks (" ") around a name, you must
insert a caret ( ^ ) before each special script character. Special characters are ^, | , <, and >.
Insert a caret before each special script character when used with the terminals -n, -o, -f, and -p. For
example, to specify storage array CLI>CLIENT, enter this string:
-n CLI^>CLIENT
Insert one caret (^) before each special script character when used within a string literal in a script command.
For example, to change the name of a storage array to FINANCE_|_PAYROLL, enter the following string:
-c "set storageArray userLabel=\"FINANCE_^|_PAYROLL\";"
Formatting Rules for Script Commands
Syntax unique to a specific script command is explained in the Notes section at the end of each script
command description.
SANtricity_10.77 February 2011
LSI Corporation
- 1012 -
Case sensitivity – The script commands are not case sensitive. You can type the script commands in
lowercase, uppercase, or mixed case. (In the following command descriptions, mixed case is used as an aid
to reading the command names and understanding the purpose of the command.)
Spaces – You must enter spaces in the script commands as they are shown in the command descriptions.
Square brackets – Square brackets are used in two ways:
As part of the command syntax.
To indicate that the parameters are optional. The description of each parameter tells you if you need to
enclose a parameter value in square brackets.
Parentheses – Parentheses shown in the command syntax enclose specific choices for a parameter. That is,
if you want to use the parameter, you must enter one of the values enclosed in parentheses. Generally, you
do not include parentheses in a script command; however, in some instances, when you enter lists, you must
enclose the list in parentheses. Such a list might be a list of tray ID values and slot ID values. The description
of each parameter tells you if you need to enclose a parameter value in parentheses.
Vertical bars – Vertical bars in a script command indicate “or” and separate the valid values for the
parameter. For example, the syntax for the raidLevel parameter in the command description appears as
follows:
raidLevel=(0 | 1 | 3 | 5 | 6)
To use the raidLevel parameter to set RAID Level 5, enter this value:
raidLevel=5
Drive locations – The CLI commands that identify drive locations support both high-capacity drive trays and
low-capacity drive trays. A high-capacity drive tray has drawers that hold the drives. The drawers slide out of
the drive tray to provide access to the drives. A low-capacity drive tray does not have drawers. For a high-
capacity drive tray, you must specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the
slot in which a drive resides. For a low-capacity drive tray, you need only specify the ID of the drive tray and
the ID of the slot in which a drive resides. For a low-capacity drive tray, an alternative method for identifying
a location for a drive is to specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of
the slot in which a drive resides. Separate the ID values with a comma. If you enter more than one set of ID
values, separate each set of values with a space. Enclose the set of values in parentheses. For example:
(1,1 1,2 1,3 1,4 2,1 2,2 2,3 2,4)
or, for a high-capacity drive tray, this example:
(1,1,1 1,2,2 1,3,3 1,4,4 2,1,1 2,2,2 2,3,3 2,4,4)
Italicized terms – Italicized terms in the command indicate a value or information that you need to provide.
For example, when you encounter the italicized term:
numberOfDrives
Replace the italicized term with a value for the number of drives that you want to include with the script
command.
Semicolon – Script commands must end with a semicolon (;). You can enter more than one script command
on the command line or in a script file. For example, a semicolon is used to separate each script command in
the following script file.
SANtricity_10.77 February 2011

create volume volumeGroup=3 userLabel=”v6” capacity=1gb owner=b;
Usage Guidelines
This list provides guidelines for writing script commands on the command line:
You must end all commands with a semicolon (;).
You can enter more than one command on a line, but you must separate each command with a
semicolon (;).
You must separate each base command and its associated primary parameters and secondary
parameters with a space.
The script engine is not case sensitive. You can enter commands by using uppercase letters, lowercase
letters, or mixed-case letters.
Add comments to your scripts to make it easier for you and future users to understand the purpose of the
script commands. (For information about how to add comments, see "Adding Comments to a Script File.")
NOTE While the CLI commands and the script commands are not case sensitive, user labels (such as
for volumes, hosts, or host ports) are case sensitive. If you try to map to an object that is identified by a user
label, you must enter the user label exactly as it is defined, or the CLI commands and the script commands
will fail.
Detailed Error Reporting
Data collected from an error encountered by the CLI is written to a file. Detailed error reporting under the CLI
works as follows:
If the CLI must abnormally end running CLI commands and script commands, error data is collected and
saved before the CLI finishes.
The CLI saves the error data by writing the data to a standard file name.
The CLI automatically saves the data to a file. Special command line options are not required to save the
error data.
You are not required to perform any action to save the error data to a file.
The CLI does not have any provision to avoid over-writing an existing version of the file that contains error
data.
For error processing, errors appear as two types:
Terminal errors or syntax errors that you might enter
Exceptions that occur as a result of an operational error
SANtricity_10.77 February 2011
LSI Corporation
- 1014 -
When the CLI encounters either type of error, the CLI writes information that describes the error directly to
the command line and sets a return code. Depending on the return code, the CLI also might write additional
information about which terminal caused the error. The CLI also writes information about what it was
expecting in the command syntax to help you identify any syntax errors that you might have entered.
When an exception occurs while a command is running, the CLI captures the error. At the end of processing
the command (after the command processing information has been written to the command line), the CLI
automatically saves the error information to a file.
The name of the file to which error information is saved is excprpt.txt. The CLI tries to place the
excprpt.txt file in the directory that is specified by the system property devmgr.datadir. If for any
reason the CLI cannot place the file in the directory specified by devmgr.datadir, the CLI saves the
excprpt.txt file in the same directory from which the CLI is running. You cannot change the file name or
the location. The excprpt.txt file is overwritten every time that an exception occurs. If you want to save the
information in the excprpt.txt file, you must copy the information to a new file or a new directory.

Adding Comments to a Script File
The script engine looks for certain characters or a command to show comments. You can add comments to a
script file in three ways:
1. Add text after two forward slashes (//) as a comment until an end-of-line character is reached. If the
script engine does not find an end-of-line character in the script after processing a comment, an error
message appears, and the script operation is terminated. This error usually occurs when a comment is
placed at the end of a script and you have forgotten to press the Enter key.
// Deletes the existing configuration.
set storageArray resetConfiguration=true;
2. Add text between /* and */ as a comment. If the script engine does not find both a starting comment
notation and an ending comment notation, an error message appears, and the script operation is
terminated.

/* Deletes the existing configuration */
set storageArray resetConfiguration=true;
3. Use the show statement to embed comments in a script file that you want to appear while the script file is
running. Enclose the text that you want to appear by using double quotation marks (“ ”).
show “Deletes the existing configuration”;
set storageArray resetConfiguration=true;
Firmware Compatibility Levels
The script commands and the command parameters do not run under all versions of the controller firmware.
The script commands in the following sections list the minimum firmware levels under which the script
commands can run. In the script commands, the firmware levels are listed under the heading “Minimum
Firmware Level.” This list describes how to interpret the information about the firmware levels.
If a script command does not list a minimum controller firmware level, the script command and all of the
parameters associated with that script command can run under any level of controller firmware.
A controller firmware number without any explanatory information indicates that the controller firmware
level applies to the entire script command and all of the parameters for that script command.
A controller firmware number that is associated with a parameter indicates the minimum controller
firmware level under which the parameter can run.
NOTE The minimum controller firmware level indicates support by the software that releases the
command, as well as support by all storage management software that picks up usage. CLI support
capabilities depend on the hardware used. When an unsupported command is entered, an error message
appears.
Examples of Firmware Compatibility Levels
The create hostGroup command has the following section.
Minimum Firmware Level
5.20
This level indicates that the entire script command runs under a minimum of controller firmware version 5.20.
The show volume command has the following section.
Minimum Firmware Level
5.00
5.43 adds the summary parameter
These notations indicate that the script command and all of the parameters except summary run under a
minimum of controller firmware version 5.00. The summary parameter runs under a minimum of controller
firmware version 5.43.

Script Commands
ATTENTION The script commands are capable of damaging a configuration and causing loss of
data access if not used correctly – Command operations are performed as soon as you run the commands.
Some commands can immediately delete configurations or data. Before using the script commands, make
sure that you have backed up all data, and have saved the current configuration so that you can reinstall it if
the changes you make do not work.
The description of each scriptcommand is intended to provide all of the information that you need to be
able to use the command. If, however, you have questions about command usage, these sections provide
additional information that can help you use the script commands:
“Naming Conventions” lists the general rules for entering the names of storage array entities, such as
volumes or drives, with the script commands.
“Formatting CLI Commands” lists the general formatting rules that apply to the CLI command wrapper.
“Formatting Rules for Script Commands” lists the general formatting rules that apply to the script
command syntax.
“Firmware Compatibility Levels” explains how to interpret the firmware level information.
“Commands Listed by Function” lists the script commands organized into groups related to the physical
features, the logical features, and the operational features of the storage array.
“Commands Listed Alphabetically” lists the script commands alphabetically and, for each script command,
includes script command name, syntax, and parameters.
IMPORTANT Terminology differences – The names of components and features change from time
to time; however, the command syntax does not change at the same time. You will notice minor differences
between the terminology used to describe components and features and the terminology used in the syntax to
describe those same items when used in a command name, a parameter, or a variable.

userLabel
The alphanumeric identifier (including - and _) that you
want to give the new volume group in which the mirror
repository volume will be loacated. Enclose the volume
group identifier in square brackets ([ ]).
repositoryVolumeGroup The name of the mirror repository volume group where
the mirror repository volume is located. (To determine the
names of the volume groups in your storage array, run the
show storageArray profile command.)
driveMediaType The type of drive media that you want to use for the mirror
repository volume group. Valid drive media are these:
HDD – Use this option when you have hard drives in the
drive tray.
SSD – Use this option when you have solid state drives
in the drive tray.
unknown – Use if you are not sure what types of drive
media are in the drive tray.
allMedia – Use this option when you want to use all
types of drive media that are in the drive tray.
Use this parameter when you use the
repositoryDriveCount parameter.
You must use this parameter when you have more than one
type of drive media in your storage array.
SANtricity_10.77 February 2011
LSI Corporation
- 1028 -
Parameter Description
driveType The type of drive that you want to use in the mirror volume.
You cannot mix drive types.
You must use this parameter when you have more than one
type of drive in your storage array.
Valid drive types are :
fibre
SATA
SAS
If you do not specify a drive type, the command defaults to
fibre.
Use this parameter when you use the
repositoryDriveCount parameter.
freeCapacityArea The index number of the free space in an existing volume
group that you want to use to create the mirror repository
volume. Free capacity is defined as the free capacity
between existing volumes in a volume group. For example,
a volume group might have the following areas: volume
1, free capacity, volume 2, free capacity, volume 3, free
capacity. To use the free capacity following volume 2, you
would specify:
freeCapacityArea=2
Run the show volumeGroup command to determine if a
free capacity area exists.
repositoryDriveCount The number of unassigned drives that you want to use for
the mirror repository volume.
trayLossProtect The setting to enforce tray loss protection when you
create the mirror repository volume. To enforce tray loss
protection, set this parameter to TRUE. The default value is
FALSE.
drawerLossProtect The setting to enforce drawer loss protection when you
create the mirror repository volume. To enforce drawer loss
protection, set this parameter to TRUE. The default value is
FALSE.
dataAssurance The setting to specify that a volume group, and the volumes
within the volume group, has data assurance protection to
make sure that the data maintains its integrity. When you
use this parameter, only protected drives can be used for
the volume group. These settings are valid:
none – The volume group does not have data
assurance protection.
enabled – The volume group has data assurance
protection. The volume group supports protected
information and is formatted with protection information
enabled.

Notes
The repositoryDrives parameter supports both high-capacity drive trays and low-capacity drive trays.
A high-capacity drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide
access to the drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you
must specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive
resides. For a low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in
which a drive resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive
is to specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a
drive resides.
If the drives that you select for the repositoryDrives parameter are not compatible with other parameters
(such as the repositoryRAIDLevel parameter), the script command returns an error, and Remote Volume
Mirroring is not activated. The error returns the amount of space that is needed for the mirror repository
volume. You can then re-enter the command, and specify the appropriate amount of space.
If you enter a value for the repository storage space that is too small for the mirror repository volumes, the
controller firmware returns an error message that provides the amount of space that is needed for the mirror
repository volumes. The command does not try to activate Remote Volume Mirroring. You can re-enter the
command by using the value from the error message for the repository storage space value.
When you assign the drives, if you set the trayLossProtect parameter to TRUE and have selected more
than one drive from any one tray, the storage array returns an error. If you set the trayLossProtect
parameter to FALSE, the storage array performs operations, but the volume group that you create might not
have tray loss protection.
When the controller firmware assigns the drives, if you set the trayLossProtect parameter to TRUE, the
storage array returns an error if the controller firmware cannot provide drives that result in the new volume
group having tray loss protection. If you set the trayLossProtect parameter to FALSE, the storage array
performs the operation even if it means that the volume group might not have tray loss protection.
The drawerLossProtect parameter defines if data on a volume is accessible if a drawer fails. When you
assign the drives, if you set the drawerLossProtect parameter to TRUE and select more than one drive
from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter to
FALSE, the storage array performs operations, but the volume group that you create might not have drawer
loss protection.
You must set the trayLossProtect parameter and the drawerLossProtect parameter to the same
value. Both of the parameters must be either TRUE or FALSE. If the trayLossProtect parameter and the
drawerLossProtect parameter are set to different values, the storage array returns an error.

Autoconfigure Storage Array
This command automatically configures a storage array. Before you enter the autoConfigure
storageArray command, run the show storageArray autoConfiguration command. The show
storageArray autoConfiguration command returns configuration information in the form of a list of
valid drive types, RAID levels, volume information, and hot spare information. (This list corresponds to the
parameters for the autoConfigure storageArray command.) The controllers audit the storage array
and then determine the highest RAID level that the storage array can support and the most efficient volume
definition for the RAID level. If the configuration that is described by the returned list is acceptable, you can
enter the autoConfigure storageArray command without any parameters. If you want to modify the
configuration, you can change the parameters to meet your configuration requirements. You can change a
single parameter or all of the parameters. After you enter the autoConfigure storageArray command,
the controllers set up the storage array by using either the default parameters or those you selected.

Notes
Drives and Volume Group
A volume group is a set of drives that are logically grouped together by the controllers in the storage array.
The number of drives in a volume group is a limitation of the RAID level and the controller firmware. When
you create a volume group, follow these guidelines:
Beginning with firmware version 7.10, you can create an empty volume group so that you can reserve the
capacity for later use.
You cannot mix drive types, such as SAS, SATA and Fibre Channel, within a single volume group.
The maximum number of drives in a volume group depends on these conditions:
The type of controller
The RAID level
RAID levels include: 0, 1, 10, 3, 5, and 6.
In a CDE3992 or a CDE3994 storage array, a volume group with RAID level 0 and a volume group
with RAID level 10 can have a maximum of 112 drives.
In a CE6998 storage array, a volume group with RAID level 0 and a volume group with RAID level 10
can have a maximum of 224 drives.
A volume group with RAID level 3, RAID level 5, or RAID level 6 cannot have more than 30 drives.
A volume group with RAID level 6 must have a minimum of five drives.
If a volume group with RAID level 1 has four or more drives, the storage management software
automatically converts the volume group to a RAID level 10, which is RAID level 1 + RAID level 0.
If a volume group contains drives that have different capacities, the overall capacity of the volume group
is based on the smallest capacity drive.
To enable tray loss protection, you must create a volume group that uses drives located in at least three
drive trays.
Hot Spares
Hot spare drives can replace any failed drive in the storage array. The hot spare must be the same type of
drive as the drive that failed (that is, a SAS hot spare cannot replace a Fibre Channel drive). A hot spare must
have capacity greater than or equal to any drive that can fail. If a hot spare is smaller than a failed drive, you
cannot use the hot spare to rebuild the data from the failed drive. Hot spares are available only for RAID Level
1, RAID Level 3, RAID Level 5, or RAID Level 6.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
SANtricity_10.77 February 2011
LSI Corporation
- 1033 -
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. (A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers.) In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.
Cache Read Prefetch
Cache read prefetch lets the controller copy additional data blocks into cache while the controller reads and
copies data blocks that are requested by the host from the drive into cache. This action increases the chance
that a future request for data can be fulfilled from cache. Cache read prefetch is important for multimedia
applications that use sequential data transfers. The configuration settings for the storage array that you
use determine the number of additional data blocks that the controller reads into cache. Valid values for the
cacheReadPrefetch parameter are TRUE or FALSE.
Security Type
The securityType parameter is valid for drives that are capable of full disk encryption (FDE). With FDE,
the controller firmware can create a key and activate the drive security feature. The drive security feature
encrypts data as the data is written to the drive and decrypts the data as the data is read from the drive.
Without the key created by the controller, the data written to the drive is inaccessible.
Before you can set the securityType parameter to capable or enabled, you must create a storage array
security key. Use the create storageArray securityKey command to create a storage array security
key. These commands are related to the security key:
create storageArray securityKey
set storageArray securityKey
import storageArray securityKey
export storageArray securityKey
start secureErase (drive | drives)
enable volumeGroup [volumeGroupName] security
Minimum Firmware Level
6.10
7.10 adds RAID Level 6 capability and removes hot spare limits.
7.50 adds the securityType parameter.
7.75 adds the dataAssurance parameter.
Autoconfigure Storage Array Hot Spares
This command automatically defines and configures the hot spares in a storage array. You can run this
command at any time. This command provides the best hot spare coverage for a storage array.
SANtricity_10.77 February 2011
LSI Corporation
- 1034 -
Syntax
autoConfigure storageArray hotSpares
Parameters
None.
Notes
When you run the autoconfigure storageArray hotSpares command, the controller firmware
determines the number of hot spares to create based on the total number and type of drives in the storage
array. For Fibre Channel drives, SATA drives, and SAS drives, the controller firmware creates one hot spare
for the storage array and one additional hot spare for every 60 drives in the storage array.
Minimum Firmware Level
6.10
Check Remote Mirror Status
This command returns the status of a remote-mirror volume. Use this command to determine when the status
of the remote-mirror volume becomes Optimal.
Syntax

Parameters
Parameter Description
localVolume The name of any remote-mirror volume. The remote-mirror
volume can be the primary volume or the secondary volume
of a remote-mirror pair. Enclose the volume name in square
brackets ([ ]). If the volume name has special characters, you
also must enclose the volume name in double quotation marks
(" ").
timeout The time interval within which the software can return the
remote-mirror volume status. The timeout value is in minutes.
Notes
This command waits until the status becomes Optimal or the timeout interval expires. Use this command
when you run the Asynchronous Remote Volume Mirroring utility.

file="C:\Program Files\CLI\logs\mederr.txt"
This command does not automatically append a file extension
to the saved file. You must specify a file extension when
entering the file name.
priority The priority that the parity check has relative to host I/O
activity. Valid values are highest, high, medium, low, or
lowest.
startingLBA The starting logical block address. Use integer values.
endingLBA The ending logical block address. Use integer values.
verbose The setting to capture progress details, such as percent
complete, and to show the information as the volume parity is
being repaired. To capture progress details, set this parameter
to TRUE. To prevent capturing progress details, set this
parameter to FALSE.

Notes
The starting logical block address and the ending logical block address are useful for very large single-volume
LUNs. Running a volume parity check on a very large single volume LUN can take a long time. By defining
the beginning address and ending address of the data blocks, you can reduce the time that a volume parity
check takes to complete.

A host is a computer that is attached to the storage array and accesses the volumes on the storage array
through the host ports. You can define specific mappings to an individual host. You also can assign the host
to a host group that shares access to one or more volumes.
A host group is an optional topological element that you can define if you want to designate a collection of
hosts that share access to the same volumes. The host group is a logical entity. Define a host group only if
you have two or more hosts that share access to the same volumes.
If you do not specify a host group in which to place the host that you are creating, the newly defined host
belongs to the default host group.

array. Size is defined in units of bytes, KB, MB, GB, or TB.
SANtricity_10.77 February 2011
LSI Corporation
- 1044 -
Parameter Description
owner The controller that owns the volume. Valid controller
identifiers are a or b, where a is the controller in slot A,
and b is the controller in slot B. If you do not specify an
owner, the controller firmware determines the owner.
cacheReadPrefetch The setting to turn on or turn off cache read prefetch. To
turn off cache read prefetch, set this parameter to FALSE.
To turn on cache read prefetch, set this parameter to
TRUE.
segmentSize The amount of data (in KB) that the controller writes on
a single drive in a volume before writing data on the next
drive. Valid values are 8, 16, 32, 64, 128, 256, or 512.
usageHint The setting for both cacheReadPrefetch parameter and
the segmentSize parameter to be default values. The
default values are based on the typical I/O usage pattern
of the application that is using the volume. Valid values
are fileSystem, dataBase, or multiMedia.
trayLossProtect The setting to enforce tray loss protection when you
create the volume group. To enforce tray loss protection,
set this parameter to TRUE. The default value is FALSE.
drawerLossProtect The setting to enforce drawer loss protection when you
create the mirror repository volume group. To enforce
drawer loss protection, set this parameter to TRUE. The
default value is FALSE.
dssPreAllocate The setting to make sure that reserve capacity is allocated
for future segment size increases. The default value is
TRUE.
securityType The setting to specify the security level when creating the
volume groups and all associated volumes. These settings
are valid:
none – The volume group and volumes are not
secure.
capable – The volume group and volumes are
capable of having security set, but security has not
been enabled.
enabled – The volume group and volumes have
security enabled.
dataAssurance The setting to specify that a volume group, and the
volumes within the volume group, has data assurance
protection to make sure that the data maintains its
integrity. When you use this parameter, only protected
drives can be used for the volume group. These settings
are valid:
none – The volume group does not have data
assurance protection.
SANtricity_10.77 February 2011
LSI Corporation
- 1045 -
Parameter Description
enabled – The volume group has data assurance
protection. The volume group supports protected
information and is formatted with protection
information enabled.
Notes
You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Names
can have a maximum of 30 characters.
The driveCount parameter lets you choose the number of drives that you want to use in the volume group.
You do not need to specify the drives by tray ID and slot ID. The controllers choose the specific drives to use
for the volume group.
The owner parameter defines which controller owns the volume.
If you do not specify a capacity using the capacity parameter, all of the drive capacity that is available in the
volume group is used. If you do not specify capacity units, bytes is used as the default value.
Cache Read Prefetch
Cache read prefetch lets the controller copy additional data blocks into cache while the controller reads
and copies data blocks that are requested by the host from the drives into cache. This action increases
the chance that a future request for data can be fulfilled from cache. Cache read prefetch is important for
multimedia applications that use sequential data transfers. The configuration settings for the storage array
that you use determine the number of additional data blocks that the controller reads into cache. Valid values
for the cacheReadPrefetch parameter are TRUE or FALSE.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers. In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.
You do not need to enter a value for the cacheReadPrefetch parameter or the segmentSize parameter.
If you do not enter a value, the controller firmware uses the usageHint parameter with fileSystem as
the default value. Entering a value for the usageHint parameter and a value for the cacheReadPrefetch

parameter or a value for the segmentSize parameter does not cause an error. The value that you enter for
the cacheReadPrefetch parameter or the segmentSize parameter takes priority over the value for the
usageHint parameter.
Tray Loss Protection and Drawer Loss Protection
For tray loss protection to work, each drive in a volume group must be on a separate tray. If you set the
trayLossProtect parameter to TRUE and have selected more than one drive from any one tray, the
storage array returns an error. If you set the trayLossProtect parameter to FALSE, the storage array
performs operations, but the volume group that you create might not have tray loss protection.
Tray loss protection is not valid when you create volumes on existing volume groups.
The drawerLossProtect parameter defines if data on a volume is accessible if a drawer fails. When you
assign the drives, if you set the the drawerLossProtect parameter to TRUE and select more than one
drive from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter
to FALSE, the storage array performs operations, but the volume group that you create might not have drawer
loss protection.
You must set the trayLossProtect parameter and the drawerLossProtect parameter to the same
value. Both of the parameters must be either TRUE or FALSE. If the trayLossProtect parameter and the
drawerLossProtect parameter are set to different values, the storage array returns an error.
Security Type
The securityType parameter is valid for drives that are capable of full disk encryption (FDE). With FDE,
the controller firmware can create a key and activate the drive security feature. The drive security feature
encrypts data as the data is written to the drive and decrypts the data as the data is read from the drive.
Without the key created by the controller, the data written to the drive is inaccessible.
Before you can set the securityType parameter to capable or enabled, you must create a storage array
security key. Use the create storageArray securityKey command to create a storage array security
key. These commands are related to the security key:
create storageArray securityKey
set storageArray securityKey
import storageArray securityKey
export storageArray securityKey

array. Size is defined in units of bytes, KB, MB, GB, or
TB.
owner The controller that owns the volume. Valid controller
identifiers are a or b, where a is the controller in slot A,
and b is the controller in slot B. If you do not specify an
owner, the controller firmware determines the owner.
cacheReadPrefetch The setting to turn on or turn off cache read prefetch. To
turn off cache read prefetch, set this parameter to FALSE.
To turn on cache read prefetch, set this parameter to
TRUE.
segmentSize The amount of data (in KB) that the controller writes on
a single drive in a volume before writing data on the next
drive. Valid values are 8, 16, 32, 64, 128, 256, or 512.
usageHint The settings for both the cachReadPrefetch parameter
and the segmentSize parameter to be default values.
The default values are based on the typical I/O usage
pattern of the application that is using the volume. Valid
values are fileSystem, dataBase, or multiMedia.
trayLossProtect The setting to enforce tray loss protection when you
create the repository. To enforce tray loss protection, set
this parameter to TRUE. The default value is FALSE.
drawerLossProtect The setting to enforce drawer loss protection when you
create the mirror repository volume. To enforce drawer
loss protection, set this parameter to TRUE. The default
value is FALSE.
dssPreAllocate The setting to make sure that reserve capacity is
allocated for future segment size increases. This default
value is TRUE.
securityType The setting to specify the security level when creating
the volume groups and all associated volumes. These
settings are valid:
none – The volume group and volumes are not
secure.
capable – The volume group and volumes are
capable of having security set, but security has not
been enabled.

Parameter Description
enabled – The volume group and volumes have
security enabled.
dataAssurance The setting to specify that a volume group, and the
volumes within the volume group, has data assurance
protection to make sure that the data maintains its
integrity. When you use this parameter, only protected
drives can be used for the volume group. These settings
are valid:
none – The volume group does not have data
assurance protection.
enabled – The volume group has data assurance
protection. The volume group supports protected
information and is formatted with protection
information enabled.
Notes
The drives parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity
drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the
drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify
the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a
low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive
resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify
the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.
If you set the raidLevel parameter to RAID 1, the controller firmware takes the list of drives and pairs them
by using this algorithm:
Data
drive = X
Parity
drive = N/2 +
X
In this algorithm X is 1 to N/2, and N is the number of drives in the list. For example, if you have six drives, the
mirror pairs are as follows:
Data Parity
1 N/2 + 1 = 4
2 N/2 + 2 = 5
3 N/2 + 3 = 6
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the
names. Names can have a maximum of 30 characters.
The owner parameter defines which controller owns the volume. The preferred controller ownership of a
volume is the controller that currently owns the volume group.
SANtricity_10.77 February 2011
LSI Corporation
- 1053 -
If you do not specify a capacity using the capacity parameter, all of the drive capacity that is available in the
volume group is used. If you do not specify capacity units, bytes is used as the default value.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers. In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.
Cache Read Prefetch
Cache read prefetch lets the controller copy additional data blocks into cache while the controller reads and
copies data blocks that are requested by the host from the drive into cache. This action increases the chance
that a future request for data can be fulfilled from cache. Cache read prefetch is important for multimedia
applications that use sequential data transfers. The configuration settings for the storage array that you
use determine the number of additional data blocks that the controller reads into cache. Valid values for the
cacheReadPrefetch parameter are TRUE or FALSE.
You do not need to enter a value for the cacheReadPrefetch parameter or the segmentSize parameter.
If you do not enter a value, the controller firmware uses the usageHint parameter with fileSystem as
the default value. Entering a value for the usageHint parameter and a value for the cacheReadPrefetch
parameter or a value for the segmentSize parameter does not cause an error. The value that you enter for
the cacheReadPrefetch parameter or the segmentSize parameter takes priority over the value for the
usageHint parameter.
Tray Loss Protection and Drawer Loss Protection
For tray loss protection to work, each drive in a volume group must be on a separate tray. If you set the
trayLossProtect parameter to TRUE and have selected more than one drive from any one tray, the
storage array returns an error. If you set the trayLossProtect parameter to FALSE, the storage array
performs operations, but the volume group that you create might not have tray loss protection.
Tray loss protection is not valid when you create volumes on existing volume groups.
The drawerLossProtect parameter defines if data on a volume is accessible if a drawer fails. When you
assign the drives, if you set the the drawerLossProtect parameter to TRUE and select more than one
drive from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter
to FALSE, the storage array performs operations, but the volume group that you create might not have drawer
loss protection.
SANtricity_10.77 February 2011
LSI Corporation
- 1054 -
You must set the trayLossProtect parameter and the drawerLossProtect parameter to the same
value. Both of the parameters must be either TRUE or FALSE. If the trayLossProtect parameter and the
drawerLossProtect parameter are set to different values, the storage array returns an error.
Security Type
The securityType parameter is valid for drives that are capable of full disk encryption (FDE). With FDE,
the controller firmware can create a key and activate the drive security feature. The drive security feature
encrypts data as the data is written to the drive and decrypts the data as the data is read from the drive.
Without the key created by the controller, the data written to the drive is inaccessible.
Before you can set the securityType parameter to capable or enabled, you must create a storage array
security key. Use the create storageArray securityKey command to create a storage array security
key. These commands are related to the security key:
create storageArray securityKey
enable volumeGroup [volumeGroupName] security
export storageArray securityKey
import storageArray securityKey
set storageArray securityKey
start secureErase (drive | drives)

Parameters
Parameter Description
primary The name of an existing volume on the local storage array that
you want to use for the primary volume. Enclose the primary
volume name in double quotation marks (" ").
secondary The name of an existing volume on the remote storage array
that you want to use for the secondary volume. Enclose the
secondary volume name in double quotation marks (" ").
remoteStorageArrayNameThe name of the remote storage array. Enclose the remote
storage array name in double quotation marks (" ").
remoteStorageArrayWwnThe World Wide Identifier (WWID) of the remote storage
array. Enclose the WWID in double quotation marks (" ").
remotePassword The password for the remote storage array. Use this
parameter when the remote storage array is password
protected. Enclose the password in double quotation marks
(" ").
syncPriority The priority that full synchronization has relative to host I/O
activity. Valid values are highest, high, medium, low, or
lowest.
autoResync The settings for automatic resynchronization between the
primary volumes and the secondary volumes of a remote-
mirror pair. This parameter has these values:
enabled– Automatic resynchronization is turned on. You
do not need to do anything further to resynchronize the
primary volume and the secondary volume.
disabled– Automatic resynchronization is turned off.
To resynchronize the primary volume and the secondary
volume, you must run the resume remoteMirror
command.
writeOrder The write order for data transmission between the primary
volume and the secondary volume. Valid values are
preserved or notPreserved.
writeMode How the primary volume writes to the secondary volume. Valid
values are synchronous or asynchronous.
Notes
You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Names
can have a maximum of 30 characters.
When you choose the primary volume and the secondary volume, the secondary volume must be of equal or
greater size than the primary volume. The RAID level of the secondary volume does not have to be the same
as the primary volume.

Product shipments using the CE6998 or CE7900 controller define a maximum of 128 remote mirrors. The
CDE3992 and CDE3994 controllers can define a maximum of 64 remote mirrors.
Passwords are stored on each storage array in a management domain. If a password was not previously
set, you do not need a password. The password can be any combination of a alphanumeric characters with
a maximum of 30 characters. (You can define a storage array password by using the set storageArray
command.)
Synchronization priority defines the amount of system resources that are used to synchronize the data
between the primary volume and the secondary volume of a mirror relationship. If you select the highest
priority level, the data synchronization uses the most system resources to perform the full synchronization,
which decreases performance for host data transfers.
The writeOrder parameter applies only to asynchronous mirrors and makes them become part of a
consistency group. Setting the writeOrder parameter to preserved causes the remote-mirror pair to
transmit data from the primary volume to the secondary volume in the same order as the host writes to the
primary volume. In the event of a transmission link failure, the data is buffered until a full synchronization
can occur. This action can require additional system overhead to maintain the buffered data, which slows
operations. Setting the writeOrder parameter to notPreserved frees the system from having to maintain
data in a buffer, but it requires forcing a full synchronization to make sure that the secondary volume has the
same data as the primary volume.

Create Snapshot Volume
This command creates a snapshot volume of a base volume. You can also use this command to create a
new repository volume group if one does not already exist, or if you would prefer a different repository volume
group. This command defines three ways to create a snapshot volume:
In a new repository volume group created from user-defined drives
In a new repository volume group created from a user-defined number of drives
In an existing repository volume group
If you choose to define a number of drives, the controller firmware chooses which drives to use for the
snapshot volume.

defaults to fibre.
Use this parameter when you use the
repositoryDriveCount parameter.
freeCapacityArea The index number of the free space in an existing
volume group that you want to use to create the
snapshot repository volume. Free capacity is
defined as the free capacity between existing
volumes in a volume group. For example, a
volume group might have these areas: volume 1,
free capacity, volume 2, free capacity, volume 3,
free capacity. To use the free capacity following
volume 2, you would specify:
freeCapacityArea=2
Run the show volumeGroup command to
determine if a free capacity area exists.
warningThresholdPercent The percentage of repository capacity at
which you receive a warning that the snapshot
repository volume is nearing full. Use integer

Parameter Description
repositoryUserLabel The name that you want to give to the snapshot
repository volume. Enclose the snapshot
repository volume name in double quotation
marks (" ").
repositoryFullPolicy How you want snapshot processing to continue
if the snapshot repository volume is full. You
can choose to fail writes to the base volume
(failBaseWrites) or fail the snapshot
volume (failSnapshot). The default value is
failSnapshot.
enableSchedule Use this parameter to turn on or to turn off the
ability to schedule a snapshot operation. To turn
on snapshot scheduling, set this parameter to
TRUE. To turn off snapshot scheduling, set this
parameter toFALSE.
schedule Use this parameter to schedule a snapshot
operation.
You can use one of these options for setting a
schedule for a snapshot operation:
immediate
startDate
scheduleDay
startTime
scheduleInterval
endDate
noEndDate
timesPerDay
See the "Notes" section for information explaining
how to use these options.
Notes
The volume that you are taking a snapshot of must be a standard volume in the storage array. The maximum
number of snapshot volumes that you can create is one-half of the total number of volumes that are
supported by a controller.
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the
names. Names can have a maximum of 30 characters.
One technique for naming the snapshot volume and the snapshot repository volume is to add a hyphenated
suffix to the original base volume name. The suffix distinguishes between the snapshot volume and the
snapshot repository volume. For example, if you have a base volume with a name of Engineering Data, the
snapshot volume can have a name of Engineering Data-S1, and the snapshot repository volume can have a
name of EngineeringData-R1.
SANtricity_10.77 February 2011
LSI Corporation
- 1061 -
If you do not choose a name for either the snapshot volume or the snapshot repository volume, the storage
management software creates a default name by using the base volume name. An example of the snapshot
volume name that the controllers might create is, if the base volume name is aaa and does not have a
snapshot volume, the default snapshot volume name is aaa-1. If the base volume already has n-1 number
of snapshot volumes, the default name is aaa-n. An example of the snapshot repository volume name that
the controller might create is, if the base volume name is aaa and does not have a snapshot repository
volume, the default snapshot repository volume name is aaa-R1. If the base volume already has n-1 number
of snapshot repository volumes, the default name is aaa-Rn.
If you do not specify the unconfigured space or free space, the snapshot repository volume is placed in the
same volume group as the base volume. If the volume group where the base volume resides does not have
enough space, this command fails.
The repositoryDrives parameter supports both high-capacity drive trays and low-capacity drive trays.
A high-capacity drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide
access to the drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you
must specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive
resides. For a low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in
which a drive resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive
is to specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a
drive resides.
Tray Loss Protection and Drawer Loss Protection
When you assign the drives, if you set the trayLossProtect parameter to TRUE and have selected more
than one drive from any one tray, the storage array returns an error. If you set the trayLossProtect
parameter to FALSE, the storage array performs operations, but the volume group that you create might not
have tray loss protection.
When the controller firmware assigns the drives, if you set the trayLossProtect parameter to TRUE, the
storage array returns an error if the controller firmware cannot provide drives that result in the new volume
group having tray loss protection. If you set the trayLossProtect parameter to FALSE, the storage array
performs the operation even if it means the volume group might not have tray loss protection.
The drawerLossProtect parameter defines if data on a volume is accessible if a drawer fails. When you
assign the drives, if you set the drawerLossProtect parameter to TRUE and select more than one drive
from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter to
FALSE, the storage array performs operations, but the volume group that you create might not have drawer
loss protection.
If you have a storage configuration that includes a drive tray that has drawers to hold the drives, follow these
guidelines when configuring tray loss protection:
If you set trayLossProtect to TRUE, then you must set drawerLossProtect to TRUE.
If you set trayLossProtect to FALSE, then you can set drawerLossProtect to either TRUE or
FALSE.
If you set trayLossProtect to TRUE and drawerLossProtect to FALSE, the storage array returns an
error.

Scheduling Snapshots
The enableSchedule parameter and the schedule parameter provide a way for you to schedule automatic
snapshots. Using these parameters, you can schedule snapshots daily, weekly, or monthly (by day or by
date). The enableSchedule parameter turns on or turns off the ability to schedule snapshots. When you
enable scheduling, you use the schedule parameter to define when you want the snapshots to occur.
This list explains how to use the options for the schedule parameter:
immediate – As soon as you enter the command, a snapshot volume is created and a copy-on-write
operation begins.
startDate – A specific date on which you want to create a snapshot volume and perform a copy-on-
write operation. The format for entering the date is MM:DD:YY. If you do not provide a start date, the
current date is used. An example of this option is startDate=06:27:11.
scheduleDay - A day of the week on which you want to create a snapshot volume and perform a copy-
on-write operation. The values that you can enter are: monday, tuesday, wednesday, thursday,
friday, saturday, sunday, and all. An example of this option is scheduleDay=wednesday.
startTime – The time of a day that you want to create a snapshot volume and start performing a copy-
on-write operation. The format for entering the time is HH:MM, where HH is the hour and MM is the minute
past the hour. Use a 24-hour clock. For example, 2:00 in the afternoon is 14:00. An example of this option
is startTime=14:27.
scheduleInterval – An amount of time, in minutes, that you want to have as a minimum between
copy-on-write operation. It is possible for you to create a schedule in which you have overlapping copy-
on-write operations because of the duration a copy operation. You can make sure that you have time
between copy-on-write operations by using this option. The maximum value for the scheduleInterval
option is 1440 minutes. An example of this option is scheduleInterval=180.
endDate – A specific date on which you want to stop creating a snapshot volume and end the copy-
on-write operations. The format for entering the date is MM:DD:YY. An example of this option is
endDate=11:26:11.
noEndDate – Use this option if you do not want your scheduled copy-on-write operation to end. If you
later decide to end the copy-on-write operations you must re-enter the create snapshotVolume
command and specify an end date.
timesPerDay – The number of times that you want the schedule to run in a day. An example of this
option is timesPerDay=4.
If you also use the scheduleInterval option, the firmware will choose between the timesPerDay option
and the scheduleInterval option by selecting the lowest value of the two options. The firmware calculates
an integer value for the scheduleInterval option by dividing 1440 by a the scheduleInterval option
value that you set. For example, 1440/180 = 8. The firmware then compares the timesPerDay integer value
with the calculated scheduleInterval integer value and uses the smaller value.
To remove a schedule, use the delete snapshot command with the schedule parameter. The delete
snapshot command with the schedule parameter deletes only the schedule, not the snapshot volume.

Create Storage Array Security Key
This command creates a new security key for a storage array that has full disk encryption (FDE) drives. This
command also sets the security definitions and sets the state to Security Enabled.
NOTE Before you create a storage array security key, you must set the password for the storage array.
Use the set storageArray command to set the password for the storage array.
Syntax
create storageArray securityKey
[keyIdentifier="keyIdentifierString"] |
passPhrase="passPhraseString" |
file="fileName" |
commitSecurityKey=(TRUE | FALSE)
Parameters
Parameter Description
keyIdentifier A character string that you can read that is a wrapper
around a security key. Enclose the key identifier in double
quotation marks (" ").
passPhrase A character string that encrypts the security key so that
you can store the security key in an external file. Enclose
the pass phrase in double quotation marks (" ").
For information about the correct form for creating a
valid pass phrase, refer to the Notes in this command
description.
file The file path and the file name to which you want to save
the security key. For example:
file="C:\Program Files\CLI\sup\seckey.slk"
IMPORTANT – You must add a file extension of .slk to
the end of the file name.
Enclose the file path and name in double quotation marks
(" ").
commitSecurityKey This parameter commits the security key identifier to the
storage array for all FDE drives as well as the controllers.
After the security key identifier is committed, a key is
required to read data or write data. The data can only be
read or changed by using a key, and the drive can never
be used in a non-secure mode without rendering the data
useless or totally erasing the drive.
Notes
Use this command for local key management only.
To use this command successfully, you need to have enough FDE drives to create at least one volume group.
SANtricity_10.77 February 2011
LSI Corporation
- 1064 -
The controller firmware creates a lock that restricts access to the FDE drives. FDE drives have a state called
Security Capable. When you create a security key, the state is set to Security Enabled, which restricts access
to all FDE drives that exist within the storage array.
You can have a storage array configuration with more than one set of encrypted volume groups. Each volume
group can have a unique security key. The character string generated by the keyIdentifier parameter is
a string that you can read and that enables you to identify the security key that you need. You can create a
keyIdentifer by using one of these methods:
You can enter up to 189 alphanumeric characters for a key identifier. The key identifier cannot have these
characters:
White spaces
Punctuation
Symbols
If you do not enter the keyIdentifer parameter, the controller automatically generates the
keyIdentifer parameter.
Additional characters are automatically generated and appended to the end of the string that you enter for the
key identifier. If you do not enter any string for the keyIdentifier parameter, the key identifier consists of
only the characters that are automatically generated.
Your pass phrase must meet these criteria:
The pass phrase must be between eight and 32 characters long.
The pass phrase must contain at least one uppercase letter.
The pass phrase must contain at least one lowercase letter.
The pass phrase must contain at least one number.
The pass phrase must contain at least one non-alphanumeric character, for example, < > @ +.
NOTE If your pass phrase does not meet these criteria, you will receive an error message and will be
asked to retry the command.

ATTENTION Starting a volume copy operation overwrites all existing data on the target volume, makes
the target volume read-only to hosts, and fails all snapshot volumes associated with the target volume, if any
exist. If you have used the target volume as a copy before, be sure you no longer need the data or have it
backed up.
This command creates volume copies in two ways:
Volume copy without snapshot
Volume copy with snapshot

If you use volume copy without snapshot you cannot write to the source volume until the copy operation is
complete. If you want to be able to write to the source volume before the copy operation is complete, use
volume copy with snapshot. You can select volume copy with snapshot through the optional parameters in the
command syntax.
After completion of the volume copy with snapshot operation, the snapshot is disabled.
NOTE You can have a maximum of eight volume copies in progress at one time. If you try to create
more than eight volume copies at one time, the controllers return a status of Pending until one of the volume
copies that is in progress finishes and returns a status of Complete.
Syntax
create volumeCopy source="sourceName"
target="targetName"
[copyPriority=(highest | high | medium | low | lowest)
targetReadOnlyEnabled=(TRUE | FALSE)
copyType=(offline | online)
repositoryPercentOfBase=(20 |40 | 60 | 120 | default) |
repositoryGroupPreference=(sameAsSource | otherThanSource |
... default)]
Parameters
Parameter Description
source The name of an existing volume that you want to
use as the source volume. Enclose the source
volume name in double quotation marks (" ").
target The name of an existing volume that you want
to use as the target volume. Enclose the target
volume name in double quotation marks (" ").
copyPriority The priority that volume copy has relative to host
I/O activity. Valid values are highest, high,
medium, low, or lowest.
targetReadOnlyEnabled The setting so that you can write to the target
volume or only read from the target volume. To
write to the target volume, set this parameter to
FALSE. To prevent writing to the target volume, set
this parameter to TRUE.
copyType Use this parameter to create a volume copy with a
snapshot. Creating a volume copy with a snapshot
enables you to continue to write to the source
volume while creating the volume copy. To create
a volume copy with a snapshot, set this parameter
to online. To create a volume copy without a
snapshot, set this parameter to offline.
If you do not use this parameter, the volume copy
is created without a snapshot.

Parameter Description
repositoryPercentOfBase This parameter determines the size of the
repository volume for the snapshot when you
are creating a volume copy with a snapshot.
The size of the repository volume is expressed
as a percentage of the source volume, which is
also called the base volume. Valid values for this
parameter are 20, 40, 60, 120, and default.
The default value is 20. If you do not use this
parameter, the firmware uses a value of 20
percent.
You must use the copyType parameter with the
repositoryPercentOfBase parameter.
repositoryGroupPreference This parameter determines to whichvolume group
the snapshot repository volume is written. You
have these choices:
sameAsSource – The snapshot repository
volume is written to the same volume group as
the source volume if space is available.
otherThanSource – The snapshot repository
volume is written to a different volume group.
Firmware determines which volume group
based on available space on the volume
groups.
default – The snapshot repository volume is
written to any volume group that has space.
For best performance, use the sameAsSource
option.
You must use the copyType parameter with the
repositoryGroupPreference parameter.
Notes
You can use any combination of alphanumeric characters, happens, and underscores for the names. Names
can have a maximum of 30 characters.
Copy priority defines the amount of system resources that are used to copy the data between the source
volume and the target volume of a volume copy pair. If you select the highest priority level, the volume
copy uses the most system resources to perform volume copy, which decreases performance for host data
transfers.

Parameters
Parameter Description
drives The drives that you want to assign to the volume group
that you want to create. For high-capacity drive trays,
specify the tray ID value, the drawer ID value, and the
slot ID value for each drive that you assign to the volume
group. For low-capacity drive trays, specify the tray ID
value and the slot ID value for each drive that you assign
to the volume group. Tray ID values are 0 to 99. Drawer
ID values are 1 to 5. Slot ID values are 1 to 32. Enclose
the tray ID values, the drawer ID values, and the slot ID
values in parentheses.
raidLevel The RAID level of the volume group that contains the
volume. Valid values are 0, 1, 3, 5, or 6.
userLabel The alphanumeric identifier (including - and _) that you
want to give the new volume group. Enclose the volume
group identifier in double quotation marks (" ").
driveMediaType The type of drive media that you want to use for the
volume group
You must use this parameter when you have more than
one type of drive media in your storage array.
Valid drive media are:
HDD – Use this option when you have hard drives in
the drive tray.
SSD – Use this option when you have solid state
drives in the drive tray.
unknown – Use if you are not sure what types of drive
media are in the drive tray.
allMedia – Use this option when you want to use all
types of drive media that are in the drive tray.
driveType The type of drive that you want to use in the volume. You
cannot mix drive types.
You must use this parameter when you have more than
one type of drive in your storage array.

- 1068 -
Parameter Description
Valid drive types are :
fibre
SATA
SAS
If you do not specify a drive type, the command defaults to
fibre.
trayLossProtect The setting to enforce tray loss protection when you
create the volume group. To enforce tray loss protection,
set this parameter to TRUE. The default value is FALSE.
drawerLossProtect The setting to enforce drawer loss protection when
you create the volume group. To enforce drawer loss
protection, set this parameter to TRUE. The default value
is FALSE.
securityType The setting to specify the security level when creating the
volume groups and all associated volumes. These settings
are valid:
none – The volume group and volumes are not
secure.
capable – The volume group and volumes are
capable of having security set, but security has not
been enabled.
enabled – The volume group and volumes have
security enabled.
dataAssurance The setting to specify that a volume group, and the
volumes within the volume group, has data assurance
protection to make sure that the data maintains its
integrity. When you use this parameter, only protected
drives can be used for the volume group. These settings
are valid:
none – The volume group does not have data
assurance protection.
enabled – The volume group has data assurance
protection. The volume group supports protected
information and is formatted with protection
information enabled.
Notes
The drives parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity
drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the
drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify
the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a
low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive
resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify
the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.

If you do not specify a capacity by using the capacity parameter, all of the drive capacity that is available in
the volume group is used. If you do not specify capacity units, bytes is used as the default value.
Cache Read Prefetch
The cacheReadPrefetch command lets the controller copy additional data blocks into cache while the
controller reads and copies data blocks that are requested by the host from the drives into cache. This
action increases the chance that a future request for data can be fulfilled from cache. Cache read prefetch
is important for multimedia applications that use sequential data transfers. The configuration settings for the
storage array that you use determine the number of additional data blocks that the controller reads into cache.
Valid values for the cacheReadPrefetch parameter are TRUE or FALSE.
You do not need to enter a value for the cacheReadPrefetch parameter or the segmentSize parameter.
If you do not enter a value, the controller firmware uses the usageHint parameter with fileSystem as
the default value. Entering a value for the usageHint parameter and a value for the cacheReadPrefetch
parameter or a value for the segmentSize parameter does not cause an error. The value that you enter for
the cacheReadPrefetch parameter or the segmentSize parameter takes priority over the value for the
usageHint parameter.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers. In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.
Security Type
The securityType parameter is valid for drives that are capable of full disk encryption (FDE). With FDE,
the controller firmware can create a key and activate the drive security feature. The drive security feature
encrypts data as the data is written to the drive and decrypts the data as the data is read from the drive.
Without the key created by the controller, the data written to the drive is inaccessible.
Before you can set the securityType parameter to capable or enabled, you must create a storage array
security key. Use the create storageArray securityKey command to create a storage array security
key. These commands are related to the security key:
create storageArray securityKey
enable volumeGroup [volumeGroupName] security
export storageArray securityKey
import storageArray securityKey
SANtricity_10.77 February 2011
LSI Corporation

set storageArray securityKey
start secureErase (drive | drives)
Tray Loss Protection and Drawer Loss Protection
For tray loss protection to work, each drive in a volume group must be on a separate tray. If you set the
trayLossProtect parameter to TRUE and have selected more than one drive from any one tray, the
storage array returns an error. If you set the trayLossProtect parameter to FALSE, the storage array
performs operations, but the volume group that you create might not have tray loss protection.
Tray loss protection is not valid when you create volumes on existing volume groups.
The drawerLossProtect parameter defines if data on a volume is accessible if a drawer fails. When you
assign the drives, if you set the the drawerLossProtect parameter to TRUE and select more than one drive
from any one drawer, the storage array returns an error. If you set the drawerLossProtect parameter to
FALSE, the storage array performs operations, but the volume group that you create might not have drawer
loss protection.
You must set the trayLossProtect parameter and the drawerLossProtect parameter to the same
value. Both of the parameters must be either TRUE or FALSE. If the trayLossProtect parameter and the
drawerLossProtect parameter are set to different values, the storage array returns an error.

Discrete lines are control lines and status lines that are connected between two controllers in a controller tray.
The discrete lines diagnostic test lets each controller check that control signal transitions can be observed at
the control inputs of the alternate controller. The discrete lines diagnostic test automatically runs after each
power-cycle or each controller-reset. You can run the discrete lines diagnostic test after you have replaced a
component that failed the initial discrete lines diagnostic test. This test applies only to the CE6998 controller
tray and the CE7900 controller tray. The discrete lines diagnostic test returns one of these messages:
When the discrete lines diagnostic test runs successfully, this message appears:
The controller discrete lines successfully passed the diagnostic
test. No failures were detected.
If the discrete lines diagnostic test fails, this message appears:
One or more controller discrete lines failed the diagnostic test.
If the CLI cannot run the discrete lines diagnostic test, the CLI returns Error 270, which means that the

Stop all I/O activity to the storage array before you download the firmware image. The download drive
command blocks all I/O activity until the download finishes or fails; however, as a precaution, make sure
that all I/O activity that might affect the drive is stopped.
Make sure that the firmware image file is compatible with the drive tray. If you download a firmware
image file that is not compatible with the drive tray that you have selected, the drive tray might become
unusable.
Do not make any configuration changes to the storage array while you download drive firmware. Trying
to make a configuration change can cause the firmware download to fail and make the selected drives
unusable.
When you download the firmware to the drives, you must provide the full path and file name to the firmware
image that is stored on your system.
You can use download drive command to test the firmware on one drive before you install the firmware on
all of the drives in a storage array. The download returns one of these statuses:

The drive parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity
drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the
drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify
the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a
low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive
resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify
the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.

Recopy Volume Copy
This command reinitiates a volume copy operation using an existing volume copy pair.
ATTENTION Starting a volume copy operation overwrites all existing data on the target volume, makes
the target volume read-only to hosts, and fails all snapshot volumes associated with the target volume, if any
exist. If you have used the target volume as a copy before, be sure you no longer need the data or have it
backed up.
This command works with volume copy pairs that you created with a snapshot volume or without a snapshot
volume.
Syntax
recopy volumeCopy target [targetName]

- 1093 -
Parameters
Parameter Description
target The name of the target volume for which you want to
reinitiate a volume copy operation. Enclose the target
volume name in square brackets ([ ]). If the target
volume name has special characters, you also must
enclose the target volume name in double quotation
marks (" ").
source The name of the source volume for which you want to
reinitiate a volume copy operation. Enclose the source
volume name in square brackets ([ ]). If the source
volume name has special characters, you also must
enclose the source volume name in double quotation
marks (" ").
copyPriority The priority that the volume copy has relative to host I/
O activity. Valid values are highest, high, medium,
low, or lowest.
targetReadOnlyEnabled The setting so that you can write to the target volume
or only read from the target volume. To write to
the target volume, set this parameter to FALSE.
To prevent writing to the target volume, set this
parameter to TRUE.
copyType Use this parameter to create a volume copy with a
snapshot. Creating a volume copy with a snapshot
enables you to continue to write to the source volume
while creating the volume copy. To reinitiate a volume
copy with a snapshot, set this parameter to online.
To reinitiate a volume copy with out a snapshot, set
this parameter to offline.
Notes
Copy priority defines the amount of system resources that are used to copy the data between the source
volume and the target volume of a volume copy pair. If you select the highest priority level, the volume copy
uses the most system resources to perform the volume copy, which decreases performance for host data
transfers.

256, or 512.
dssPreallocate The setting to turn on or turn off allocating volume
storage capacity for future segment size changes. To
turn on allocation, set this parameter to TRUE. To turn
off allocation, set this parameter to FALSE.
SSID The storage array subsystem identifier of a volume.
owner The controller that owns the volume. Valid controller
identifiers are a or b, where a is the controller in
slot A, and b is the controller in slot B. If you do not
specify an owner, the controller firmware determines
the owner.
cacheReadPrefetch The setting to turn on or turn off cache read prefetch.
To turn off cache read prefetch, set this parameter
to FALSE. To turn on cache read prefetch, set this
parameter to TRUE.
dataAssurance The setting to specify that a volume group, and the
volumes within the volume group, has data assurance
protection to make sure that the data maintains its
integrity. When you use this parameter, only protected
drives can be used for the volume group. These
settings are valid:
none – The volume group does not have data
assurance protection.
enabled – The volume group has data
assurance protection. The volume group supports
protected information and is formatted with
protection information enabled.

Notes
The storage management software collects recovery profiles of the monitored storage arrays and saves the
profiles on a storage management station.
The drive parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity
drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the
drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify
the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a
low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive
resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify
the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.
If you attempt to recover a volume using the drive parameter or the drives parameter and the drives are
in an unassigned state, the controller automatically creates a new volume group. Use the newVolumeGroup
parameter to specify a name for the new volume group.
You can use any combination of alphanumeric characters,underscore (_), hyphen(-), and pound (#) for the
names. Names can have a maximum of 30 characters.
The owner parameter defines which controller owns the volume. The preferred controller ownership of a
volume is the controller that currently owns the volume group.
Preallocating Storage Capacity
The dssPreallocate parameter enables you to assign capacity in a volume for storing information that
is used to rebuild a volume. When you set the dssPreallocate parameter to TRUE, the storage space
allocation logic in the controller firmware preallocates the space in a volume for future segment size changes.
The preallocated space is the maximum allowable segment size. The dssPreallocate parameter is
necessary for properly recovering volume configurations that are not retievable from the controller data base.
To turn off the preallocation capability, setdssPreallocate to FALSE.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. (A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers.) In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.

Cache Read Prefetch
Cache read prefetch lets the controller copy additional data blocks into cache while the controller reads and
copies data blocks that are requested by the host from disk into cache. This action increases the chance
that a future request for data can be fulfilled from cache. Cache read prefetch is important for multimedia
applications that use sequential data transfers. The configuration settings for the storage array that you
use determine the number of additional data blocks that the controller reads into cache. Valid values for the
cacheReadPrefetch parameter are TRUE or FALSE.

Re-create Remote Volume Mirroring Repository Volume
This command creates a new Remote Volume Mirroring repository volume (also called a mirror repository
volume) by using the parameters defined for a previous mirror repository volume. The underlying requirement
is that you have previously created a mirror repository volume. When you use this command, you can define
the mirror repository volume in one of three ways: user-defined drives, user-defined volume group, or user-
defined number of drives for the mirror repository volume. If you choose to define a number of drives, the
controller firmware chooses which drives to use for the mirror repository volume.
Syntax (User-Defined Drives)
recreate storageArray mirrorRepository
repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDrives=(trayID1,slotID1 ... trayIDn,slotIDn)
[trayLossProtect=(TRUE | FALSE)
dataAssurance=(none | enabled)]
Syntax (User-Defined Volume Group)

repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDriveCount=numberOfDrives
[driveType=(fibre | SATA | SAS)]
[trayLossProtect=(TRUE | FALSE)
dataAssurance=(none | enabled)]
Parameters
Parameter Description
repositoryRAIDLevel The RAID level for the mirror repository volume. Valid
values are 1, 3, 5, or 6.
repositoryDrives The drives for the mirror repository volume. Specify
the tray ID and slot ID for each drive that you assign
to the mirror repository volume. Tray ID values are 0
to 99. Slot ID values are 1 to 32. Enclose the tray ID
values and the slot ID values in parentheses.
repositoryVolumeGroup The name of the volume group where the mirror
repository volume is located.

Parameter Description
freeCapacityArea The index number of the free space in an existing
volume group that you want to use to re-create the
mirror repository volume. Free capacity is defined
as the free capacity between existing volumes in a
volume group. For example, a volume group might
have the following areas: volume 1, free capacity,
volume 2, free capacity, volume 3, free capacity. To
use the free capacity following volume 2, you would
specify:
freeCapacityArea=2
Run the show volumeGroup command to determine
if a free capacity area exists.
repositoryDriveCount The number of unassigned drives that you want to use
for the mirror repository volume.
driveType The type of drive that you want to use for the mirror
repository volume. You cannot mix drive types.
You must use this parameter when you have more
than one type of drive in your storage array.
Valid drive types are :
fibre
SATA
SAS
If you do not specify a drive type, the command
defaults to fibre.
trayLossProtect The setting to enforce tray loss protection when you
create the mirror repository volume. To enforce tray
loss protection, set this parameter to TRUE. The
default value is FALSE.
dataAssurance The setting to specify that a volume group, and the
volumes within the volume group, has data assurance
protection to make sure that the data maintains its
integrity. When you use this parameter, only protected
drives can be used for the volume group. These
settings are valid:
none – The volume group does not have data
assurance protection.
enabled – The volume group has data
assurance protection. The volume group supports
protected information and is formatted with
protection information enabled.

Notes
If you enter a value for the storage space of the mirror repository volume that is too small, the controller
firmware returns an error message, which states the amount of space that is needed for the mirror repository
volume. The command does not try to change the mirror repository volume. You can re-enter the command
by using the value from the error message for the storage space value of the mirror repository volume.
When you assign the drives, if you set the trayLossProtect parameter to TRUE and have selected more
than one drive from any one tray, the storage array returns an error. If you set the trayLossProtect
parameter to FALSE, the storage array performs operations, but the mirror repository volume that you create
might not have tray loss protection.
When the controller firmware assigns the drives, if you set the trayLossProtect parameter to TRUE, the
storage array returns an error if the controller firmware cannot provide drives that result in the new mirror
repository volume having tray loss protection. If you set the trayLossProtect parameter to FALSE, the
storage array performs the operation even if it means that the mirror repository volume might not have tray
loss protection.

Re-create Snapshot
This command starts a fresh copy-on-write operation by using an existing snapshot volume. You can re-
create a single snapshot volume or re-create multiple snapshot volumes. If you choose to re-create multiple
snapshot volumes, you can re-create from two to the maximum number of snapshot volumes that your
storage array can support.
Syntax
recreate snapshot (volume [volumeName] |
volumes [volumeName1 ... volumeNameN])
[userLabel="snapshotVolumeName"
warningThresholdPercent=percentValue
repositoryFullPolicy (failBaseWrites | failSnapshot)]
Parameters
Parameter Description
volume or volumes The name of the specific volume for which
you want to start a fresh copy-on-write
operation. You can enter more than one
volume name. Enclose the volume name in
square brackets ([ ]). If the volume name has
special characters, you must also enclose the
volume name in double quotation marks (" ").

Parameter Description
userLabel The name of the snapshot volume. Enclose
the snapshot volume name in double
quotation marks (" "). If you enter more than
one snapshot volume name, this command
fails.
warningThresholdPercent The percentage of repository capacity
at which you receive a warning that the
snapshot repository volume is nearing full.
Use integer values. For example, a value of
70 means 70 percent. The default value is 50.
repositoryFullPolicy The type of processing that you want to
continue if the snapshot repository volume is
full. You can choose to fail writes to the base
volume (failBaseWrites) or fail writes to
the snapshot volume (failSnapshot). The
default value is failSnapshot.
Notes
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the
names. Names can have a maximum of 30 characters.
If you do not specify a value for the warningThresholdPercent parameter or the
repositoryFullPolicy parameter, the previously set value is used.
Recreating a Single Snapshot Volume or Multiple Snapshot Volumes with Optional Parameters
If you specify one or more of the optional parameters, the re-create operation processes each snapshot
volume separately.
If you try to use the same user label for more than one volume, the command will fail.
If you do not set the warningThresholdPercent parameter or the repositoryFullPolicy
parameter, values that you previously set are used.
Recreating Multiple Snapshot Volumes without Optional Parameters
If you list multiple snapshot volumes to be re-created but do not specify any of the optional parameters,
the re-create operation processes the snapshot volumes as a "batch" process.
Validation checks for the necessary snapshot-restarted preconditions are performed before restarting
any snapshot. If any of the listed snapshot volumes fail the validation, the entire command fails and the
snapshot volumes are not re#created. If the validation is successful for all of the snapshot volumes in the
list, but one or more of the snapshots in the list fails to restart, the entire command fails and none of the
snapshots are re-created.
During snapshot re-creation, all affected volumes (snapshots, base, and repository) are appropriately
quiesced and I/O operations are resumed to all affected volumes after all snapshots have been
successfully re-created.

Parameters
Parameter Description
allVolumes This parameter removes the LUN mapping from all of the
volumes.
volume or volumes The name of the specific volume that you want to remove
from the LUN mapping. You can enter more than one volume
name. Enclose the volume name in double quotation marks
(" ") inside of square brackets ([ ]).
accessVolume This parameter removes the access volume.
host The name of the host to which the volume is mapped. Enclose
the host name in double quotation marks (" ").
hostGroup The name of the host group that contains the host to which
the volume is mapped. Enclose the host group name in double
quotation marks (" "). The defaultGroup value is the host
group that contains the host to which the volume is mapped.
Notes
The access volume is the volume in a SAN environment that is used for communication between the storage
management software and the storage array controller. The access volume uses a LUN address and
consumes 20 MB of storage space that is not available for application data storage. An access volume is
required only for in-band managed storage arrays.
ATTENTION Removing an access volume can damage your configuration – The agent uses
the access volumes to communicate with a storage array. If you remove an access volume mapping for a
storage array from a host that has an agent running on it, the storage management software is no longer able
to manage the storage array through the agent.
You must use the host parameter and the hostGroup parameter when you specify a non-access volume or
an access volume. The Script Engine ignores the host parameter or the hostGroup parameter when you
use the allVolumes parameter or the volumes parameter.

replacementDrive=trayID,drawerID,slotID
Parameters
Parameter Description
drive The location of the drive that you want to reconstruct. For
high-capacity drive trays, specify the tray ID value, the
drawer ID value, and the slot ID value of the drive that
you want to revive. For low-capacity drive trays, specify
the tray ID value and the slot ID value of the drive that
you want to revive. Tray ID values are 0 to 99. Drawer ID
values are 1 to 5. Slot ID values are 1 to 32. Enclose the
tray ID value, the drawer ID value, and the slot ID value in
square brackets ([ ]).
replacementDrive The location of the drive that you want to use for a
replacement. For high-capacity drive trays, specify the tray
ID value, the drawer ID value, and the slot ID value for
the drive. For low-capacity drive trays, specify the tray ID
value and the slot ID value for the drive. Tray ID values
are 0 to 99. Drawer ID values are 1 to 5. Slot ID values

Notes
The drive parameter supports both high-capacity drive trays and low-capacity drive trays. A high-capacity
drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access to the
drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must specify
the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides. For a
low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a drive
resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to specify
the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive resides.

Reset Controller
This command resets a controller, and it is disruptive to I/O operations.
ATTENTION When you reset a controller, the controller is removed from the data path and is not
available for I/O operations until the reset operation is complete. If a host is using volumes that are owned by
the controller being reset, the I/O directed to the controller is rejected. Before resetting the controller, either
make sure that the volumes that are owned by the controller are not in use or make sure that a multi-path
driver is installed on all of the hosts that use these volumes.
Syntax
reset controller [(a | b)]
Parameter
Parameter Description
controller The controller that you want to reset. Valid controller identifiers
are a or b, where a is the controller in slot A, and b is the
controller in slot B. Enclose the controller identifier in square
brackets ([ ]). If you do not specify a controller owner, the
controller firmware returns a syntax error.
Notes
The controller that receives the reset controller command resets the controller specified. For example, if the
reset controller command is sent to controller A to request a reset of controller A, then controller A reboots
itself by doing a soft reboot. If the reset controller command is sent to controller A to request a reset of
controller B, then controller A holds controller B in reset and then releases controller B from reset, which is a
hard reboot. A soft reboot in some products only resets the IOC chip. A hard reboot resets both the IOC and
the expander chips in the controller.

Reset Storage Array Battery Install Date
This command resets the age of the batteries in a storage array to zero days. You can reset the age of the
batteries for an entire storage array or the age of a battery in a specific controller or in a specific battery pack.
Syntax
reset storageArray batteryInstallDate
(controller=[(a | b)] | batteryPack [left | right])
Parameters
Parameter Description
controller The controller that contains the battery for which you want to
reset the age. Valid controller identifiers are a or b, where a is
the controller in slot A, and b is the controller in slot B. Use the
controller parameter only for controllers with batteries.
batteryPack The battery pack contains both a left battery and a right
battery. Valid identifiers are left or right, where left is
the battery that supports the controller in slot A, and right
is the battery that supports the controller in slot B. Use the
batteryPack parameter only for controller trays with battery
packs.
Notes
A controller might have a battery associated with it, so the controller is identified as either a or b. With the
release of the CE7900 controller tray, battery packs inside the interconnect-battery canister are identified as
either left or right. If the command statement uses the wrong parameter, an error appears.

Reset Storage Array Diagnostic Data
This command resets the NVSRAM that contains the diagnostic data for the storage array. This command
does not delete the diagnostic data. This command replaces the Needs Attention status with the Diagnostic
Data Available status. The old diagnostic data is written over automatically when new data is captured. The
memory that contains the diagnostic data is also cleared when the controllers reboot. Before you reset the
diagnostic data, use the save storageArray diagnosticData command to save the diagnostic data to
a file.

Reset Storage Array Infiniband Statistics Baseline
This command resets the Infiniband statistics baseline to 0 for the storage array.
Syntax
reset storageArray ibStatsBaseline
Parameters
None.
Notes
This command does not actually reset the raw counts maintained in the hardware and firmware. Instead,
the firmware creates a snapshot of the current counter values and uses these values to report differences
in the counts when the statistics are retrieved. The new baseline time is applied to both controllers so that
the controller counts are synchronized with each other. If one controller resets without the other controller
resetting, the counters are no longer synchronized. The client becomes aware that the controllers are
not synchronized because the timestamp data reported along with the statistics is not the same for both
controllers.

Reset Storage Array iSCSI Baseline
This command resets the iSCSI baseline to 0 for the storage array.
Syntax

Parameters
None.
Notes
This command resets the baseline to 0 for both controllers in the storage array. The purpose of resetting
both of the controller baselines is to help make sure that the controller counts are synchronized between
the controllers. If one controller resets but the second controller does not reset, the host is informed that the
controllers are out of synchronization. The host is informed by the time stamps that are reported with the
statistics.

Notes
NOTE Before firmware version 7.75, the set controller command supported an NVSRAMByte
parameter. The NVSRAMByte parameter is deprecated and must be replaced with either the
hostNVSRAMByte parameter or the globalNVSRAMByte parameter.
When you use this command, you can specify one or more of the parameters. You do not need to use all of
the parameters.
Setting the availability parameter to serviceMode causes the alternate controller to take ownership of
all of the volumes. The specified controller no longer has any volumes and refuses to take ownership of any
more volumes. Service mode is persistent across reset cycles and power cycles until the availability
parameter is set to online.

Use the show controller NVSRAM command to show the NVSRAM information. Before making any
changes to the NVSRAM, contact your Customer and Technical Support representative to learn what regions
of the NVSRAM you can modify.
When the duplexMode option is set to TRUE, the selected Ethernet port is set to full duplex. The default
value is half duplex (the duplexMode parameter is set to FALSE).
To make sure that the IPv4 settings or the IPv6 settings are applied, you must set these iscsiHostPort
options:
enableIPV4= TRUE
enableIPV6= TRUE
The IPv6 address space is 128 bits. It is represented by eight 16-bit hexadecimal blocks separated by colons.
The maxFramePayload option is shared between IPv4 and IPv6. The payload portion of a standard Ethernet
frame is set to 1500, and a jumbo Ethernet frame is set to 9000. When using jumbo frames, all of the devices
that are in the network path should be capable of handling the larger frame size.
The portSpeed option is expressed as megabits per second (Mb/s).
Values for the portSpeed option of the iscsiHostPort parameter are in megabits per second (Mb/s).
The following values are the default values for the iscsiHostOptions:
The IPv6HopLimit option is 64.
The IPv6NdReachableTime option is 30000 milliseconds.
The IPv6NdRetransmitTime option is 1000 milliseconds.

For information about using forceOnWarning, see
the Notes.
Notes
Before you can enter this command, the drive tray must meet these conditions:
The drive tray cannot be over temperature.
The fans must have a status of Optimal.
All drive tray components must be in place.
The volumes in the drive drawer cannot be in a Degraded state. If you remove drives from the drive
drawer and a volume is already in a Degraded state, the volume can fail.
ATTENTION Do not issue this command if you cannot meet any of these conditions.
All volumes with drives in the affected drive drawer are checked to make sure that the volumes have drawer
loss protection before the command is sent. If the volumes have drawer loss protection, the Set Service
Action Allowed command proceeds without stopping I/O activity to the volume.
If any volumes in the affected drawer do not have drawer loss protection, you must stop I/O activity to those
volumes. A warning appears, which indicates that this command should not be completed.
If you are preparing a component for removal and want to override the warning that the volumes do not have
drawer loss protection, enter this parameter:
serviceAllowedIndicator=forceOnWarning
forceOnWarning sends the request to prepare to remove a component to the controller firmware, and
forces the set drawer serviceAllowedIndicator command to proceed.
To turn on or turn off the Service Action Allowed indicator light for the entire high-capacity drive tray, use the
set tray serviceAllowedIndicator command.

Set Foreign Drive to Native
A drive is considered to be native when it is a part of a volume group in a storage array. A drive is considered
to be foreign when it does not belong to a volume group in a storage array or when it fails to be imported
with the drives of a volume group that are transferred to a new storage array. The latter failure creates an
incomplete volume group on the new storage array.
Run this command to add the missing (foreign) drives back into their original volume group and to make them
part of the volume groupin the new storage array.
Use this operation for emergency recovery only: when one or more drives need to be changed from a foreign
drive status and returned to a native status within their original volume group.
ATTENTION Possible data corruption or data loss – Using this command for reasons other than
what is stated previously might result in data loss without notification.

Parameters
Parameter Description
localVolume or
localVolumes
The name of the primary volume for which you want to define
properties. You can enter more than one primary volume
name. Enclose the primary volume name in square brackets
([ ]). If the primary volume name has special characters,
you also must enclose the primary volume name in double
quotation marks (" ").
SANtricity_10.77 February 2011
LSI Corporation
- 1141 -
Parameter Description
role The setting for the volume to act as the primary volume or
the secondary volume. To define the volume as the primary
volume, set this parameter to primary. To define the volume
as the secondary volume, set this parameter to secondary.
This parameter applies only when the volume is part of a
mirror relationship.
force The role reversal is forced if the communications link between
the storage arrays is down and promotion or demotion
on the local side results in a dual-primary condition or a
dual-secondary condition. To force a role reversal, set this
parameter to TRUE. The default value is FALSE.
syncPriority The priority that full synchronization has relative to host I/O
activity. Valid values are highest, high, medium, low, or
lowest.
autoResync The settings for automatic resynchronization between the
primary volumes and the secondary volumes of a remote-
mirror pair. This parameter has these values:
enabled – Automatic resynchronization is turned on. You
do not need to do anything further to resynchronize the
primary volume and the secondary volume.
disabled – Automatic resynchronization is turned off.
To resynchronize the primary volumes and the secondary
volume, you must run the resume remoteMirror
command.
writeOrder This parameter defines write order for data transmission
between the primary volume and the secondary volume. Valid
values are preserved or notPreserved.
writeMode This parameter defines how the primary volume writes to
the secondary volume. Valid values are synchronous or
asynchronous.
Notes
When you use this command, you can specify one or more of the optional parameters.
Synchronization priority defines the amount of system resources that are used to synchronize the data
between the primary volumes and the secondary volumes of a mirror relationship. If you select the highest
priority level, the data synchronization uses the most system resources to perform the full synchronization,
which decreases the performance for host data transfers.
The writeOrder parameter applies only to asynchronous mirrors and makes them become part of a
consistency group. Setting the writeOrder parameter to preserved causes the remote-mirror pair to
transmit data from the primary volume to the secondary volume in the same order as the host writes to the
primary volume. In the event of a transmission link failure, the data is buffered until a full synchronization
can occur. This action can require additional system overhead to maintain the buffered data, which slows
SANtricity_10.77 February 2011
LSI Corporation
- 1142 -
operations. Setting the writeOrderparameter to notPreserved frees the system from having to maintain
data in a buffer, but it requires forcing a full synchronization to make sure that the secondary volume has the
same data as the primary volume.

Parameters
Parameter Description
errorAction How the session responds if an error is
encountered during processing. You can
choose to stop the session if an error is
encountered, or you can continue the
session after encountering an error. The
default value is stop. (This parameter
defines the action for execution errors,
not syntax errors. Some error conditions
might override the continue value.)
password The password for the storage array.
Enclose the password in double quotation
marks (" ").
performanceMonitorInterval The frequency of gathering performance
data. Enter an integer value for the polling
interval, in seconds, for which you want
to capture data. The range of values is 3
to 3600 seconds. The default value is 5
seconds.
performanceMonitorIterations The number of samples to capture. Enter
an integer value. The range of values
for samples captured is 1 to 3600. The
default value is 5.

userLabel A new name that you want to give to a snapshot
volume. Enclose the new snapshot volume name
in double quotation marks (" ").
warningThresholdPercent The percentage of repository capacity at
which you receive a warning that the snapshot
repository is nearing full. Use integer values. For
example, a value of 70 means 70 percent. The
default value is 50.
repositoryFullPolicy How you want snapshot processing to continue
if the snapshot repository volume is full. You
can choose to fail writes to the base volume
(failBaseWrites) or fail writes to the snapshot
volume (failSnapshot). The default value is
failSnapshot.

how to use these options.
Notes
When you use this command, you can specify one or more of the optional parameters.
You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Names
can have a maximum of 30 characters.
You can set the warningThresholdPercent parameter and the repositoryFullPolicy parameter for
both the snapshot repository volume or the snapshot volume.
Scheduling Snapshots
The enableSchedule parameter and the schedule parameter provide a way for you to schedule automatic
snapshots. Using these parameters, you can schedule snapshots daily, weekly, or monthly (by day or by
date). The enableSchedule parameter turns on or turns off the ability to schedule snapshots. When you
enable scheduling, you use the schedule parameter to define when you want the snapshots to occur.
This list explains how to use the options for the schedule parameter:
immediate – As soon as you enter the command, a snapshot volume is created and a copy-on-write
operation begins.
startDate – A specific date on which you want to create a snapshot volume and perform a copy-on-
write operation. The format for entering the date is MM:DD:YY. If you do not provide a start date, the
current date is used. An example of this option is startDate=06:27:11.
SANtricity_10.77 February 2011
LSI Corporation
- 1145 -
scheduleDay - A day of the week on which you want to create a snapshot volume and perform a copy-
on-write operation. You can enter these values: monday, tuesday, wednesday, thursday, friday,
saturday, sunday, and all. An example of this option is scheduleDay=wednesday.
startTime – The time of a day that you want to create a snapshot volume and start performing a copy-
on-write operation. The format for entering the time is HH:MM, where HH is the hour and MM is the minute
past the hour. Use a 24-hour clock. For example, 2:00 in the afternoon is 14:00. An example of this option
is startTime=14:27.
scheduleInterval – An amount of time, in minutes, that you want to have as a minimum between
copy-on-write operation.You can possibly create a schedule in which you have overlapping copy-on-write
operations because of the duration a copy operation. You can make sure that you have time between
copy-on-write operations by using this option. The maximum value for the scheduleInterval option is
1440 minutes. An example of this option is scheduleInterval=180.
endDate – A specific date on which you want to stop creating a snapshot volume and end the copy-
on-write operations. The format for entering the date is MM:DD:YY. An example of this option is
endDate=11:26:11.
noEndDate – Use this option if you do not want your scheduled copy-on-write operation to end. If you
later decide to end the copy-on-write operations you must re-enter the create snapshotVolume
command and specify an end date.
timesPerDay – The number of times that you want the schedule to run in a day. An example of this
option is timesPerDay=4.
If you also use the scheduleInterval option, the firmware chooses between the timesPerDay option
and the scheduleInterval option by selecting the lowest value of the two options. The firmware calculates
an integer value for the scheduleInterval option by dividing 1440 by a the scheduleInterval option
value that you set. For example, 1440/180 = 8. The firmware then compares the timesPerDay integer value
with the calculated scheduleInterval integer value and uses the smaller value.
To remove a schedule, use the delete snapshot command with the schedule parameter. The delete
snapshot command with the schedule parameter deletes only the schedule, not the snapshot volume.

Auto Support Data
When enabled, the set storageArray autoSupportConfig command causes all configuration and
state information for the storage array to be returned each time a critical Major Event Log (MEL) event is
detected. The configuration and state information is returned in the form of an object graph. The object graph
contains all relevant logical and physical objects and their associated state information for the storage array.
The set storageArray autoSupportConfig command collects configuration and state information in
this way:
Automatic collection of the configuration and state information occurs every 72 hours. The configuration
and state information is saved to the storage array zip archive file. The archive file has a time stamp that
is used to manage the archive files.
Two storage array zip archive files are maintained for each storage array. The zip archive files are kept on
a drive. After the 72-hour time period is exceeded, the oldest archive file is always overwritten during the
new cycle.
After you enable automatic collection of the configuration and state information using this command, an
initial collection of information starts. Collecting information after the you issue the command makes sure
that one archive file is available and starts the time stamp cycle.
You can run the set storageArray autoSupportConfig command on more than one storage array.

When you define cache block sizes, use the 4-KB cache block size for storage arrays that require I/O streams
that are typically small and random. Use the 8-KB cache block size when the majority of your I/O streams are
larger than 4 KB but smaller than 8 KB. Use the 16-KB cache block size or the 32-KB cache block size for
storage arrays that require large data transfer, sequential, or high-bandwidth applications.
The cacheBlockSize parameter defines the supported cache block size for all of the volumes in the storage
array. Not all controller types support all cache block sizes. For redundant configurations, this parameter
includes all of the volumes that are owned by both controllers within the storage array.
Cache Flush Start and Cache Flush Stop
When you define values to start a cache flush, a value that is too low increases the chance that data needed
for a host read is not in the cache. A low value also increases the number of drive writes that are necessary to
maintain the cache level, which increases system overhead and decreases performance.
SANtricity_10.77 February 2011

When setting storage array cache settings, the value of the cacheFlushStart parameter must always
be greater than or equal to the value of the cacheFlushStop parameter. For example, if the value of the
cacheFlushStart parameter is set to 80, you may set the value of the cacheFlushStop parameter within
the range of 0 to 80.
When you define values to stop a cache flush, the lower the value, the higher the chance that the data for a
host read requires a drive read rather than reading from the cache.
Default Host Type
When you define host types, if Storage Partitioning is enabled, the default host type affects only those
volumes that are mapped in the default group. If Storage Partitioning is not enabled, all of the hosts that are
attached to the storage array must run the same operating system and be compatible with the default host
type.
Media Scan Rate
Media scan runs on all of the volumes in the storage array that have Optimal status, do not have modification
operations in progress, and have the mediaScanRate parameter enabled. Use the set volume command
to enable or disable the mediaScanRate parameter.
Password
Passwords are stored on each storage array. For best protection, the password must meet these criteria:
The password must be between eight and 32 characters long.
The password must contain at least one uppercase letter.
The password must contain at least one lowercase letter.
The password must contain at least one number.
The password must contain at least one non-alphanumeric character, for example, < > @ +.
NOTE If you are using full disk encryption drives in your storage array, you must use these criteria for
your storage array password.
NOTE You must set a password for your storage array before you can create a security key for
encrypted full disk encryption drives.

Parameter
Parameter Description
icmpPingResponse This parameter turns on or turns off Echo Request
messages. Set the parameter to TRUE to turn on Echo
Request messages. Set the parameter to FALSE to turn
off Echo Request messages.
Notes
The Internet Control Message Protocol (ICMP) is used by operating systems in a network to send error
messages, test packets, and informational messages related to the IP, such as a requested service is not
available or that a host or router could not be reached. The ICMP response command sends ICMP Echo
Request messages and receives ICMP Echo Response messages to determine if a host is reachable and the
time it takes for packets to get to and from that host.

Parameters
Parameters Description
isnsIPv4ConfigurationMethod The method that you want to use to define
the iSNS server configuration. You can
enter the IP address for the IPv4 iSNS
servers by selecting static. For IPv4,
you can choose to have a Dynamic Host
Configuration Protocol (DHCP) server select
the iSNS server IP address by entering
dhcp. To enable DCHP, you must set the
isnsIPv4Address parameter to 0.0.0.0.
isnsIPv4Address The IP address that you want to use for the
iSNS server. Use this parameter with the
static value for IPv4 configurations. If you
choose to have a DHCP server set the IP

Notes
The iSNS protocol facilitates the automated discovery, management, and configuration of iSCSI devices and
Fibre Channel devices on a TCP/IP network. iSNS provides intelligent storage discovery and management
services comparable to those found in Fibre Channel networks, which allow a commodity IP network to
function in a similar capacity as a storage area network. iSNS also facilitates a seamless integration of IP
networks and Fibre Channel networks, due to its ability to emulate Fibre Channel fabric services and manage
both iSCSI devices and Fibre Channel devices.
The DHCP server passes configuration parameters, such as network addresses, to IP nodes. DHCP enables
a client to acquire all of the IP configuration parameters that it needs to operate. DHCP lets you automatically
allocate reusable network addresses.

Parameter Description
isnsListeningPort The IP address that you want to use for the iSNS server
listening port. The range of values for the listening port is
49152 to 65535. The default value is 3205.
Notes
A listening port resides on the database server and is responsible for these activities:
Listening (monitoring) for incoming client connection requests
Managing the traffic to the server
When a client requests a network session with a server, a listener receives the actual request. If the client
information matches the listener information, then the listener grants a connection to the database server.

Set Storage Array Security Key
Use this command to set the security key that is used throughout the storage array to implement the
SafeStore Drive Security premium feature. When any security-capable drive in the storage array is assigned
to a secured volume group, that drive will be security-enabled using the security key. Before you can set the
security key, you must use the create storageArray securityKey command to create the security
key.
Syntax
set storageArray securityKey
Parameters
None.
Notes
Security-capable drives have hardware to accelerate cryptographic processing and each has a unique drive
key. A security-capable drive behaves like any other drive until it is added to a secured volume group, at
which time the security-capable drive becomes security-enabled.
SANtricity_10.77 February 2011
LSI Corporation
- 1154 -
Whenever a security-enabled drive is powered on, it requires the correct security key from the controller
before it can read or write data. So, a security-enabled drive uses two keys: the drive key that encrypts and
decrypts the data and the security key that authorizes the encryption and decryption processes. The set
storageArray securityKey command commits the security key to all of the controllers and security-
enabled drives in the storage array. The full disk encryption feature ensures that if a security-enabled drive is
physically removed from a storage array, its data cannot be read by any other device unless the security key
is known.

Set Storage Array Tray Positions
This command defines the position of the trays in a storage array. You must include all of the trays in the
storage array when you enter this command.
Syntax
set storageArray trayPositions=(controller | trayID ... trayIDn)
Parameter
Parameter Description
trayPositions A list of all of the tray IDs. The sequence of the tray IDs in
the list defines the positions for the controller tray and the
drive trays in a storage array. Valid values are 0 to 99. Enter
the tray ID values separated with a space. Enclose the list
of tray ID values in parentheses. For storage arrays where
the controller tray has a predefined identifier that is not in
the range of valid tray position values, use the controller
value.
SANtricity_10.77 February 2011
LSI Corporation
- 1155 -
Notes
This command defines the position of a tray in a storage array by the position of the tray ID in the
trayPositions list. For example, if you have a controller tray with an ID set to 84 and drive trays with IDs
set to 1, 12, and 50, the trayPositions sequence (84 1 12 50) places the controller tray in the first
position, drive tray 1 in the second position, drive tray 12 in the third position, and drive tray 50 in the fourth
position. The trayPositions sequence (1 84 50 12) places the controller tray in the second position,
drive tray 1 in the first position, drive tray 50 in the third position, and drive tray 12 in the fourth position.
NOTE You must include all of the trays in the storage array in the list defined by the trayPositions
parameter. If the number of trays in the list does not match the total number of trays in the storage array, an
error message appears.

Parameter
Parameter Description
unnamedDiscoverySession This parameter turns on or turns off unnamed
discovery sessions. Set the parameter to TRUE
to turn on unnamed discovery sessions. Set
the parameter to FALSE to turn off unnamed
discovery sessions.
Notes
Discovery is the process where initiators determine the targets that are available. Discovery occurs at power-
on/initialization and also if the bus topology changes, for example, if an extra device is added.
An unnamed discovery session is a discovery session that is established without specifying a target ID in
the login request. For unnamed discovery sessions, neither the target ID nor the target portal group ID are
available to the targets.

- 1163 -
Parameter Description
host The name of the host to which the volume is
mapped. Enclose the host name in double
quotation marks (" ").
hostGroup The name of the host group to which the
volume is mapped. Enclose the host group
name in double quotation marks (" ").
defaultGroup is the host group that
contains the host to which the volume is
mapped.
Notes
Host I/O errors might result in volume groups with more than 32 volumes. This operation might also result in
internal controller reboots due to the expiration of the timeout period before the operation completes. If you
experience this issue, quiesce host I/O, and try the operation again.
When you use this command, you can specify one or more of the optional parameters.
You can apply these parameters to only one volume at a time:
addCapacity
segmentSize
userLabel
logicalUnitNumber
Add Capacity, Add Drives, and Segment Size
Setting the addCapacity parameter, the addDrives parameter, or the segmentSize parameter starts a
long-running operation that you cannot stop. These long-running operations are performed in the background
and do not prevent you from running other commands. To show the progress of long-running operations, use
the show volume actionProgress command.
The addDrives parameter supports both high-capacity drive trays and low-capacity drive trays. A high-
capacity drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access
to the drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must
specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides.
For a low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a
drive resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to
specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive
resides.
Access Volume
The access volume is the volume in a SAN environment that is used for in-band communication between
the storage management software and the storage array controller. This volume uses a LUN address and
consumes 20 MB of storage space that is not available for application data storage. An access volume is
required only for in-band managed storage arrays. If you specify the accessVolume parameter, the only
property you can set is the logicalUnitNumber parameter.

250 Data is flushed after 250 ms.
500 Data is flushed after 500 ms.
750 Data is flushed after 750 ms.
1Data is flushed after 1 s.
1500 Data is flushed after 1500 ms.
2Data is flushed after 2 s.
5Data is flushed after 5 s.
10 Data is flushed after 10 s.
20 Data is flushed after 20 s.
60 Data is flushed after 60 s (1 min.).
120 Data is flushed after 120 s (2 min.).
300 Data is flushed after 300 s (5 min.).
1200 Data is flushed after 1200 s (20 min.).
3600 Data is flushed after 3600 s (1 hr).
Infinite Data in cache is not subject to any age or time
constraints. The data is flushed based on other criteria
that are managed by the controller.
Cache Without Battery Enabled
Write caching without batteries enables write caching to continue if the controller batteries are completely
discharged, not fully charged, or not present. If you set this parameter to TRUE without an uninterruptible
power supply (UPS) or other backup power source, you can lose data if the power to the storage array fails.
This parameter has no effect if write caching is disabled.
Modification Priority
Modification priority defines the amount of system resources that are used when modifying volume properties.
If you select the highest priority level, the volume modification uses the most system resources, which
decreases the performance for host data transfers.

Cache Read Prefetch
The cacheReadPrefetch parameter enables the controller to copy additional data blocks into cache while
the controller reads and copies data blocks that are requested by the host from the drive into cache. This
action increases the chance that a future request for data can be fulfilled from cache. Cache read prefetch
is important for multimedia applications that use sequential data transfers. The configuration settings for the
storage array that you use determine the number of additional data blocks that the controller reads into cache.
Valid values for the cacheReadPrefetch parameter are TRUE or FALSE.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests.
If the volume is in an environment where a single user is transferring large units of data (such as multimedia),
performance is maximized when a single data transfer request is serviced with a single data stripe. (A data
stripe is the segment size that is multiplied by the number of drives in the volume group that are used for data
transfers.) In this case, multiple drives are used for the same request, but each drive is accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.

Parameters
Parameter Description
target The name of the target volume for which you want to
define properties. Enclose the target volume name in
square brackets ([ ]). If the target volume name has
special characters, you also must enclose the target
volume name in double quotation marks (" ").
source The name of the source volume for which you want to
define properties. Enclose the source volume name in
square brackets ([ ]). If the source volume name has
special characters, you also must enclose the source
volume name in double quotation marks (" ").
copyPriority The priority that the volume copy has relative to host I/
O activity. Valid values are highest, high, medium,
low, or lowest.
targetReadOnlyEnabled The setting so that you can write to the target volume
or only read from the target volume. To write to
the target volume, set this parameter to FALSE.
To prevent writing to the target volume, set this
parameter to TRUE.
copyType Use this parameter to identify that a volume copy has
a snapshot. If the volume copy has a snapshot, set
this parameter to online. If the volume copy does
not have a snapshot, set this parameter to offline.
Notes
When you use this command, you can specify one or more of the optional parameters.

raidLevel=(0 | 1 | 3 | 5 | 6)
owner=(a | b)
SANtricity_10.77 February 2011
LSI Corporation
- 1167 -
Parameters
Parameter Description
volumeGroup The alphanumeric identifier (including - and _) of the volume
group for which you want to set properties. Enclose the
volume group identifier in square brackets ([ ]).
addDrives The location of the drive that you want to add to the volume
group. For high-capacity drive trays, specify the tray ID value,
the drawer ID value, and the slot ID value for the drive. For
low-capacity drive trays, specify the tray ID value and the
slot ID value for the drive. Tray ID values are 0 to 99. Drawer
ID values are 1 to 5. Slot ID values are 1 to 32. Enclose the
tray ID value, the drawer ID value, and the slot ID value in
parentheses.
raidLevel The RAID level for the volume group. Valid values are 0, 1, 3,
5, or 6.
owner The controller that owns the volume group. Valid controller
identifiers are a or b, where a is the controller in slot A, and b
is the controller in slot B. Use this parameter only if you want
to change the volume group owner.
Notes
Host I/O errors might result in volume groups with more than 32 volumes. This operation also might result in
internal controller reboots because the timeout period ends before the volume group definition is set. If you
experience this issue, quiesce the host I/O operations, and try the command again.
When you use this command, you can specify one or more of the parameters.
NOTE Specifying the addDrives parameter or the raidLevel parameter starts a long-running
operation that you cannot stop.
The addDrives parameter supports both high-capacity drive trays and low-capacity drive trays. A high-
capacity drive tray has drawers that hold the drives. The drawers slide out of the drive tray to provide access
to the drives. A low-capacity drive tray does not have drawers. For a high-capacity drive tray, you must
specify the identifier (ID) of the drive tray, the ID of the drawer, and the ID of the slot in which a drive resides.
For a low-capacity drive tray, you need only specify the ID of the drive tray and the ID of the slot in which a
drive resides. For a low-capacity drive tray, an alternative method for identifying a location for a drive is to
specify the ID of the drive tray, set the ID of the drawer to 0, and specify the ID of the slot in which a drive
resides.

SATA
SAS
If you do not specify a drive type, the command
defaults to fibre.
raidLevel The RAID level of the volume group that contains the
drives in the storage array. Valid RAID levels are 0, 1,
3, 5, or 6.
volumeGroupWidth The number of drives in a volume group in the storage
array, which depends on the capacity of the drives.
Use integer values.
volumeGroupCount The number of volume groups in the storage array.
Use integer values.
volumesPerGroupCount The number of equal-capacity volumes per volume

Parameter Description
hotSpareCount The number of hot spares that you want in the storage
array. Use integer values.
segmentSize The amount of data (in KB) that the controller writes
on a single drive in a volume before writing data on
the next drive. Valid values are 8, 16, 32, 64, 128,
256, or 512.
cacheReadPrefetch The setting to turn on or turn off cache read prefetch.
To turn off cache read prefetch, set this parameter
to FALSE. To turn on cache read prefetch, set this
parameter to TRUE.
securityType The setting to specify the security level when creating
the volume groups and all associated volumes. These
settings are valid:
none – The volume group and volumes are not
secure.
capable – The volume group and volumes are
capable of having security set, but security has
not been enabled.
enabled – The volume group and volumes have
security enabled.
Notes
If you do not specify any properties, this command returns the RAID Level 5 candidates for each drive type. If
RAID Level 5 candidates are not available, this command returns candidates for RAID Level 6, RAID Level 3,
RAID Level 1, or RAID Level 0. When you specify auto configuration properties, the controllers validate that
the firmware can support the properties.
Drives and Volume Group
A volume group is a set of drives that are logically grouped together by the controllers in the storage array.
The number of drives in a volume group is a limitation of the RAID level and the controller firmware. When
you create a volume group, follow these guidelines:
Beginning with firmware version 7.10, you can create an empty volume group so that you can reserve the
capacity for later use.
You cannot mix drive types, such as SAS and Fibre Channel, within a single volume group.
The maximum number of drives in a volume group depends on these conditions:
The type of controller
The RAID level
RAID levels include: 0, 1, 10, 3, 5, and 6.
In a CDE3992 or a CDE3994 storage array, a volume group with RAID level 0 and a volume group
with RAID level 10 can have a maximum of 112 drives.
In a CE6998 storage array, a volume group with RAID level 0 and a volume group with RAID level 10
can have a maximum of 224 drives.
A volume group with RAID level 3, RAID level 5, or RAID level 6 cannot have more than 30 drives.
SANtricity_10.77 February 2011
LSI Corporation
- 1186 -
A volume group with RAID level 6 must have a minimum of five drives.
If a volume group with RAID level 1 has four or more drives, the storage management software
automatically converts the volume group to a RAID level 10, which is RAID level 1 + RAID level 0.
If a volume group contains drives that have different capacities, the overall capacity of the volume group
is based on the smallest capacity drive.
To enable tray loss protection, you must create a volume group that uses drives located in at least three
drive trays.
Hot Spares
Hot spare drives can replace any failed drive in the storage array. A hot spare drive must have capacity
greater than or equal to any drive that can fail. If a hot spare drive is smaller than a failed drive, you cannot
use the hot spare drive to rebuild the data from the failed drive. Hot spare drives are available only for RAID
Level 1, RAID Level 3, RAID Level 5, or RAID Level 6.
Segment Size
The size of a segment determines how many data blocks that the controller writes on a single drive in a
volume before writing data on the next drive. Each data block stores 512 bytes of data. A data block is
the smallest unit of storage. The size of a segment determines how many data blocks that it contains. For
example, an 8-KB segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
When you enter a value for the segment size, the value is checked against the supported values that are
provided by the controller at run time. If the value that you entered is not valid, the controller returns a list of
valid values. Using a single drive for a single request leaves other drives available to simultaneously service
other requests. If the volume is in an environment where a single user is transferring large units of data (such
as multimedia), performance is maximized when a single data transfer request is serviced with a single data
stripe. (A data stripe is the segment size that is multiplied by the number of drives in the volume group that
are used for data transfers.) In this case, multiple drives are used for the same request, but each drive is
accessed only once.
For optimal performance in a multiuser database or file system storage environment, set your segment size to
minimize the number of drives that are required to satisfy a data transfer request.
Cache Read Prefetch
Cache read prefetch lets the controller copy additional data blocks into cache while the controller reads and
copies data blocks that are requested by the host from the drive into cache. This action increases the chance
that a future request for data can be fulfilled from cache. Cache read prefetch is important for multimedia
applications that use sequential data transfers. The configuration settings for the storage array that you
use determine the number of additional data blocks that the controller reads into cache. Valid values for the
cacheReadPrefetch parameter are TRUE or FALSE.

card.
extendedTestID This parameter selects the extended test option that
you want to run.
If you choose the extended parameter, you also
must also use the extendedTestID parameter and
one of the extended test options.
Extended Test Option Description
writePatterns This option writes a predefined pattern of data in
blocks to the entire cache backup device. Each block
that was written is then read back, and the data is
verified for integrity and accuracy.
random This option writes a random pattern to each flash
block in the cache backup device.
Notes
When an unexpected power loss occurs, cache memory can have data that has not been written to the
drives. This data must be preserved so that it can be written to the drives when power is restored. The
contents of the cache memory are backed up to a persistent storage device, such as a USB flash drive, a
SATA drive, or a solid state device (SSD).
The total storage capacity of the flash drives must be equal to the total cache memory, considering that all
storage space in a flash drive is not always usable. For example, in a 1-GB flash drive, approximately 968
MB is usable. Also, in some flash drives, the Cyclic Redundancy Check (CRC) needs to be stored along
with the data. Because the metadata region is persisted in these flash drives, the storage capacity for the
flash drives must be greater than the size of the cache memory.
You can run the diagnostic test on only one controller in the storage array at any one time.
Minimum Firmware Level
7.60 adds the capability for cache backup device diagnostics.
Start Cache Memory Diagnostic
This command runs extended diagnostic tests to evaluate the functionality of the cache memory in a

The address test attempts to write to specific address
offsets. The data test attempts to write several data
patterns to the address offsets. The data retention
test attempts to write a data pattern and then read
the data pattern back after a delay. The purpose
of the SRAM option is to find memory parity or error
correcting code (ECC) errors.
FIFO This option tests the active processor chip (APC)
first in, first out (FIFO) data transmission of the Zip
chip. The APC FIFO channels are tested concurrently
by writing and verifying different patterns to each
channel.

data copy operations that can copy data from one
area of the Zip SDRAM to another area of the Zip
SDRAM. This test is performed on any available
section of the Zip chip that is not busy.
RAID5Parity This option tests the ability of the Zip APC to generate
and verify RAID 5 parity data. Data buffers are set
up in processor memory and parity is generated in
processor memory. Some data buffers are set up
in parallel architecture (RPA) memory and parity is
generated for the data within the RPA memory. The
parity that is generated within processor memory is
then compared with the parity in the Zip APC.
RAID6Parity This option tests the ability of the Zip APC to generate
and verify RAID 6 parity data. Data buffers are set
up in processor memory and parity is generated in
processor memory. Some data buffers are set up
in redundant parallel architecture (RPA) memory

Extended Test Option for
iSCSI Description
internalLoopBack This option tests the ability of the physical layer (PHY)
to transmit data packets over the physical link. For
this test, the PHY is set to an internal loopback mode.
Data is then transmitted, received, and compared with
the original data. The test is run in two passes:
For the first pass, the data is predefined by the
firmware.
For the second pass, the data is generated
externally and then transmitted.
Notes
You can run the diagnostic test on only one controller in the storage array at any one time.
A controller can have either one or two host interface cards.
If a controller has one host interface card, the value for the position of each host interface card depends
on the position of the controller in the controller tray. The host interface card in the controller in controller
tray slot A has a position value of 1. The host interface card in the controller in controller tray slot B has a
position value of 2.
If a controller has two host interface cards, the value for the position of each host interface card depends
on the position of the host interface card in the controller and the position of the controller in the controller
tray. In most cases the position of the host interface card is identified with labels such as Host Card 1 and
Host Card 2 on each controller. The position value of the host interface cards are listed in this table.
Controller Host Card

If this command is unsuccessful because hardware problems prevented the completion of the export, use the
set volumeGroup forceState command. The set volumeGroup forceState command lets you
use the start volumeGroup import command to import a volume group.
After the volume group is in an Exported state or a Forced state, you can remove the drives that comprise the
volume group from the storage array. You can reinstall the drives in a different storage array.

SANtricity_10.77 February 2011
LSI Corporation
- 1221 -
Parameter
Parameter Description
volume or volumes The name of the specific volume for which you want to stop a
copy-on-write operation. You can enter more than one volume
name.
Enclose the volume names using one of these forms:
On a Windows command line: \"volumeName\"
In a Windows script engine window: ["volumeName"]
On a Linux command line: \"volumeName\"
In a Linux script engine window: [\"volumeName\"]
Notes
Names can be any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#).
Names can have a maximum of 30 characters.
One technique for naming the snapshot volume and the snapshot repository volume is to add a hyphenated
suffix to the original base volume name. The suffix distinguishes between the snapshot volume and the
snapshot repository volume. For example, if you have a base volume with a name of Engineering Data, the
snapshot volume can have a name of Engineering Data-S1, and the snapshot repository volume can have a
name of EngineeringData-R1.
If you do not choose a name for either the snapshot volume or the snapshot repository volume, the storage
management software creates a default name by using the base volume name. An example of the snapshot
volume name that the controllers might create is, if the base volume name is aaa and does not have a
snapshot volume, the default snapshot volume name is aaa-1. If the base volume already has n-1 number
of snapshot volumes, the default name is aaa-n. An example of the snapshot repository volume name that
the controller might create is, if the base volume name is aaa and does not have a snapshot repository
volume, the default snapshot repository volume name is aaa-R1. If the base volume already has n-1 number
of snapshot repository volumes, the default name is aaa-Rn.

Parameters
Parameter Description
primary or primaries The name of the volume for which you want to suspend
operation. Enclose the volume name in square brackets
([ ]). If the volume name has special characters, you must
also enclose the volume name in double quotation marks

in this command are in a write-consistency group or are
separate. For the volumes in the same write-consistency
group, set this parameter to TRUE. For the volumes that
are separate, set this parameter to FALSE.
Notes
If you set the writeConsistency parameter to TRUE, the volumes must be in a write-consistency group
(or groups). This command suspends all write-consistency groups that contain the volumes. For example, if
volumes A, B, and C are in a write-consistency group and they have remote counterparts A’, B’, and C’, the
command:
suspend remoteMirror volume ["A"] writeConsistency=TRUE
suspends A-A’, B-B’, and C-C’. If you have a write-consistency group 1={A, B, C} and write-consistency group
2={D, E, F}, the command:
suspend remoteMirror volumes=["A", "D"] writeConsistency=TRUE
suspends both write-consistency groups.

Configuring and Maintaining a Storage Array Using
the Command Line Interface
This document provides information about configuring and maintaining a storage array using a command line
interface. The information explains how to format the commands and provides examples such as creating
volume groups and volumes, configuring host, and troubleshooting if problems occur. This document also
explains how to use commands to run premium features such as Remote Volume Mirroring. A complete
listing of all of the commands and the syntax for those commands is in the Command Line Interface and
Script Commands document.
This document supports host software version 10.75 and firmware version 7.75.

About the Command Line Interface
The command line interface (CLI) is a software application that provides a way for installers, developers, and
engineers to configure and monitor storage arrays. Using the CLI, you can run commands from an operating
system prompt, such as the DOS C: prompt, a Linux operating system path, or a Solaris operating system
path.
Each command performs a specific action for managing a storage array or returning information about the
status of a storage array. You can enter individual commands, or you can run script files when you need to
perform operations more than once. For example, you can run script files when you want to install the same
configuration on several storage arrays. The CLI enables you to load a script file from a disk and run the script
file. The CLI provides a way to run storage management commands on more than one network storage array.
You can use the CLI both in installation sites and in development environments.
The CLI gives you direct access to a script engine that is a utility in the SANtricity ES Storage Manager
software (also referred to as the storage management software). The script engine runs commands that
configure and manage the storage arrays. The script engine reads the commands, or runs a script file, from
the command line and performs the operations instructed by the commands.
NOTE You can also access the script engine by using the Enterprise Management Window in the
storage management software. If you access the script engine by using the Enterprise Management Window,
you can edit or run script commands on only one storage array in the script window. You can open a script
window for each storage array in your configuration and run commands in each window. By using the CLI,
you can run commands on more than one storage array from a single command line.
You can use the command line interface to perform these actions:
Directly access the script engine and run script commands
Create script command batch files to be run on multiple storage arrays when you need to install the same
configuration on different storage arrays
Run script commands on an in-band managed storage array, an out-of-band managed storage array, or a
combination of both
Show configuration information about the network storage arrays
Add storage arrays to and remove storage arrays from the management domain
Perform automatic discovery of all of the storage arrays that are attached to the local subnet
Add or delete Simple Network Management Protocol (SNMP) trap destinations and email alert
notifications
Specify the mail server and sender email address or SNMP server for alert notifications
Show the alert notification settings for storage arrays that are currently configured in the Enterprise
Management Window
Direct the output to a standard command line display or to a named file
Structure of a CLI Command
The CLI commands are in the form of a command wrapper and elements embedded into the wrapper. A CLI
command consists of these elements:
A command wrapper identified by the term SMcli
The storage array identifier
SANtricity_10.77 February 2011
LSI Corporation
- 1234 -
Terminals that define the operation to be performed
Script commands
The CLI command wrapper is a shell that identifies storage array controllers, embeds operational terminals,
embeds script commands, and passes these values to the script engine.
All CLI commands have the following structure:
SMcli storageArray terminal script-commands;
SMcli invokes the command line interface.
storageArray is the name or the IP address of the storage array.
terminal are CLI values that define the environment and the purpose for the command.
script-commands are one or more script commands or the name of a script file that contains script
commands. (The script commands configure and manage the storage array.)
If you enter an incomplete or inaccurate SMcli string that does not have the correct syntax, parameter
names, options, or terminals, the script engine returns usage information.
For an overview of the script commands, see "About the Script Commands." For definitions, syntax, and
parameters for the script commands, refer to the Command Line Interface and Script Commands for Version
10.75.
Interactive Mode
If you enter SMcli and a storage array name but do not specify CLI parameters, script commands, or a script
file, the command line interface runs in interactive mode. Interactive mode lets you run individual commands
without prefixing the commands with SMcli.
In interactive mode, you can enter a single command, view the results, and enter the next command without
typing the complete SMcli string. Interactive mode is useful for determining configuration errors and quickly
testing configuration changes.
To end an interactive mode session, type the operating system-specific command for terminating a program,
such as Control-C on the UNIX operating system or the Windows operating system. Typing the termination
command (Control-C) while in interactive mode turns off interactive mode and returns operation of the
command prompt to an input mode that requires you to type the complete SMcli string.
CLI Command Wrapper Syntax
General syntax forms of the CLI command wrappers are listed in this section. The general syntax forms show
the terminals and the parameters that are used in each command wrapper. The conventions used in the CLI
command wrapper syntax are listed in the following table.

Command Line Terminals
Terminal Definition
host-name-or-
IP-address
Specifies either the host name or the Internet Protocol (IP) address
(xxx.xxx.xxx.xxx) of an in-band managed storage array or an
out-of-band managed storage array.
If you are managing a storage array by using a host through in-
band storage management, you must use the -n terminal or
the -w terminal if more than one storage array is connected to
the host.
If you are managing a storage array by using out-of-band
storage management through the Ethernet connection on each
controller, you must specify the host-name-or-IP-address
of the controllers.
If you have previously configured a storage array in the
Enterprise Management Window, you can specify the storage
array by its user-supplied name by using the -n terminal.
If you have previously configured a storage array in the
Enterprise Management Window, you can specify the storage
array by its World Wide Identifier (WWID) by using the -w
terminal.
-A Adds a storage array to the configuration file. If you do not follow
the -A terminal with a host-name-or-IP-address, auto-
discovery scans the local subnet for storage arrays.
-a Adds a Simple Network Management Protocol (SNMP) trap
destination or an email address alert destination.
When you add an SNMP trap destination, the SNMP
community is automatically defined as the community name
for the trap, and the host is the IP address or Domain Name
Server (DNS) host name of the system to which the trap should
be sent.
When you add an email address for an alert destination, the
email-address is the email address to which you want the
alert message to be sent.
-c Indicates that you are entering one or more script commands to
run on the specified storage array. End each command with a
semicolon (;). You cannot place more than one -c terminal on
the same command line. You can include more than one script
command after the -c terminal.
-d Shows the contents of the script configuration file. The file content
has this format:
storage-system-name host-name1 host-name2
-e Runs the commands without performing a syntax check first.
-F (uppercase) Specifies the email address from which all alerts will be sent.
SANtricity_10.77 February 2011

Terminal Definition
-f (lowercase) Specifies a file name that contains script commands that you want
to run on the specified storage array. The -f terminal is similar to
the -c terminal in that both terminals are intended for running script
commands. The -c terminal runs individual script commands. The
-f terminal runs a file of script commands.
By default, any errors that are encountered when running the
script commands in a file are ignored, and the file continues
to run. To override this behavior, use the set session
errorAction=stop command in the script file.
-g Specifies an ASCII file that contains email sender contact
information that will be included in all email alert notifications.
The CLI assumes that the ASCII file is text only, without
delimiters or any expected format. Do not use the -g terminal if a
userdata.txt file exists.
-h Specifies the host name that is running the SNMP agent to which
the storage array is connected. Use the -h terminal with these
terminals:
-a
-x
-I (uppercase) Specifies the type of information to be included in the email alert
notifications. You can select these values:
eventOnly – Only the event information is included in the
email.
profile – The event and array profile information is included
in the email.
supportBundle – The event and support bundle information
information is included in the email.
You can specify the frequency for the email deliveries using the -q
terminal.
-i (lowercase) Shows the IP address of the known storage arrays. Use the -i
terminal with the -d terminal. The file contents has this format:
storage-system-name IP-address1 IPaddress2
-m Specifies the host name or the IP address of the email server from
which email alert notifications are sent.
-n Specifies the name of the storage array on which you want to run
the script commands. This name is optional when you use a host-
name-or-IP#address. If you are using the in-band method for
managing the storage array, you must use the -n terminal if more
than one storage array is connected to the host at the specified
address. The storage array name is required when the host-
name-or-IP-address is not used. The name of the storage array
that is configured for use in the Enterprise Management Window
(that is, the name is listed in the configuration file) must not be a
duplicate name of any other configured storage array.
SANtricity_10.77 February 2011

Terminal Definition
-o Specifies a file name for all output text that is a result of running the
script commands. Use the -o terminal with these terminals:
-c
-f
If you do not specify an output file, the output text goes to standard
output (stdout). All output from commands that are not script
commands is sent to stdout, regardless of whether this terminal is
set.
-p Specifies the password for the storage array on which you want
to run commands. A password is not necessary under these
conditions:
A password has not been set on the storage array.
The password is specified in a script file that you are running.
You specify the password by using the -c terminal and this
command:
set session password=password
-q Specifies the frequency that you want to receive event notifications
and the type of information returned in the event notifications.
An email alert notification containing at least the basic event
information is always generated for every critical event.
These values are valid for the -q terminal:
everyEvent – Information is returned with every email alert
notification.
2 – Information is returned no more than once every two hours.
4 – Information is returned no more than once every four hours.
8 – Information is returned no more than once every eight
hours.
12 – Information is returned no more than once every 12 hours.
24 – Information is returned no more than once every 24 hours.
Using the -I terminal you can specify the type of information in the
email alert notifications.
If you set the -I terminal to eventOnly, the only valid value
for the -q terminal is everyEvent.
If you set the -I terminal to either the profile value or the
supportBundle value, this information is included with the
emails with the frequency specified by the -q terminal.
-quick Reduces the amount of time that is required to run a single-line
operation. An example of a single-line operation is the recreate
snapshot volume command. This terminal reduces time by not
running background processes for the duration of the command.
Do not use this terminal for operations that involve more than
one single-line operation. Extensive use of this command can
overrun the controller with more commands than the controller can

Terminal Definition
process, which causes operational failure. Also, status updates and
configuration updates that are collected usually from background
processes will not be available to the CLI. This terminal causes
operations that depend on background information to fail.
-S (uppercase) Suppresses informational messages describing the command
progress that appear when you run script commands. (Suppressing
informational messages is also called silent mode.) This terminal
suppresses these messages:
Performing syntax check
Syntax check complete
Executing script
Script execution complete
SMcli completed successfully
-s (lowercase) Shows the alert settings in the configuration file when used with the
-d terminal.
-v Shows the current global status of the known devices in a
configuration file when used with the -d terminal.
-w Specifies the WWID of the storage array. This terminal is an
alternate to the -n terminal. Use the -w terminal with the -d
terminal to show the WWIDs of the known storage arrays. The file
content has this format:
storage-system-name world-wide-ID IP-address1 IP-
address2
-X (uppercase) Deletes a storage array from a configuration.
-x (lowercase) Removes an SNMP trap destination or an email address alert
destination. The community is the SNMP community name for
the trap, and the host is the IP address or DNS host name of the
system to which you want the trap sent.
-? Shows usage information about the CLI commands.
Formatting CLI Commands
Double quotation marks (" ") that are used as part of a name or label require special consideration when you
run the CLI commands and the script commands on a Microsoft Windows operating system.
When double quotation marks (" ") are part of a name or value, you must insert a backslash (\) before each
double quotation mark character. For example:
-c "set storageArray userLabel=\"Engineering\";"
In this example, "Engineering" is the storage array name. A second example is:
-n \"My\"_Array
SANtricity_10.77 February 2011
LSI Corporation
- 1240 -
In this example, "My"_Array is the name of the storage array.
You cannot use double quotation marks (" ") as part of a character string (also called string literal) within
a script command. For example, you cannot enter the following string to set the storage array name to
"Finance" Array:
-c "set storageArray userLabel=\"\"Finance\"Array\";"
In the Linux operating system and the Solaris operating system, the delimiters around names or labels are
single quotation marks (' '). The UNIX versions of the previous examples are as follows:
-c 'set storageArray userLabel="Engineering";'
-n "My"_Array
In a Windows operating system, if you do not use double quotation marks (" ") around a name, you must
insert a caret ( ^ ) before each special script character. Special characters are ^, | , <, and >.
Insert a caret before each special script character when used with the terminals -n, -o, -f, and -p. For
example, to specify storage array CLI>CLIENT, enter this string:
-n CLI^>CLIENT
Insert one caret (^) before each special script character when used within a string literal in a script command.
For example, to change the name of a storage array to FINANCE_|_PAYROLL, enter the following string:
-c "set storageArray userLabel=\"FINANCE_^|_PAYROLL\";"
Usage Examples
The following examples show how to enter CLI commands on a command line. The examples show the
syntax, the form, and, in some examples, script commands. Examples are shown for both the Windows
operating system and the UNIX operating system. Note that the usage for the -c terminal varies depending
on your operating system. On Windows operating systems, enclose the script command following the
-c terminal in double quotation marks (" "). On UNIX operating systems, enclose the script command
following the -c terminal in single quotation marks (' '). For descriptions of the script commands used in these
examples, refer to the Command Line Interface and Script Commands for Version 10.75.
This example shows how to change the name of a storage array. The original name of the storage array is
Payroll_Array. The new name is Finance_Array.
Windows operating system:
SMcli ICTSANT -n "Payroll_Array" -c "set storageArray userLabel=\"Finance_Array\";"
UNIX operating system:
SMcli ICTSANT -n 'Payroll_Array' -c 'set storageArray userLabel="Finance_Array";'
This example shows how to delete an existing volume and create a new volume on a storage array. The
existing volume name is Stocks_<_Bonds. The new volume name is Finance. The controller host names are
finance1 and finance2. The storage array is protected, requiring the password TestArray.
Windows operating system:
SMcli finance1 finance2 -c "set session password=\"TestArray\";
SANtricity_10.77 February 2011
LSI Corporation
- 1241 -
delete volume [\"Stocks_^<_Bonds\"];
create volume driveCount[3] RAIDLEVEL=3 capacity=10GB userLabel=\"Finance\";
show storageArray healthStatus;"
UNIX operating system:
SMcli finance1 finance2 -c 'set session password="TestArray";
delete volume ["Stocks_<Bonds"];
create volume driveCount[3] RAIDLEVEL=3 capacity=10GB userLabel="Finance";
show storageArray healthStatus;'
This example shows how to run commands in a script file named scriptfile.scr on a storage array
named Example. The -e terminal causes the file to run without checking the syntax. Running a script file
without checking the syntax lets the file run more quickly; however, the file might not run correctly because
the syntax for a command might be incorrect.
SMcli -n Example -f scriptfile.scr -e
This example shows how to run commands in a script file named scriptfile.scr on a storage array
named Example. In this example, the storage array is protected by the password MyArray. Output, as a result
of commands in the script file, goes to file output.txt.
Windows operating system:
SMcli -n Example -f scriptfile.scr -p "My_Array" -o output.txt
UNIX operating system:
SMcli -n Example -f scriptfile.scr -p 'My_Array' -o output.txt
This example shows how to show all of the storage arrays in the current configuration. The command in this
example returns the host name of each storage array.
SMcli -d
If you want to know the IP address of each storage array in the configuration, add the #i terminal to the
command.

About the Script Commands
You can use the script commands to configure and manage a storage array. The script commands are
distinct from the command line interface (CLI) command wrappers. You can enter individual script commands,
or you can run a file of script commands. When you enter an individual script command, you embed the
script command in a CLI command wrapper. When you run a file of script commands, you embed the file
name in the CLI command wrapper. The script commands are processed by a script engine that performs the
following functions:
Verifies the command syntax
Interprets the commands
Converts the commands to the appropriate protocol-compliant commands
Passes the commands to the storage array
At the storage array, the storage array controllers run the script commands.
The script engine and the script commands support the storage array configuration and management
operations that are listed in the following table.
Configuration and Management Operations
Operation Activities
General storage array
configuration Resetting a configuration to defaults, labeling, checking the
health status, setting the time of day, clearing the Event Log, and
setting the media scan rate
Volume configuration

Battery management Setting the battery installation date
Structure of a Script Command
All script commands have the following structure:
SANtricity_10.77 February 2011
LSI Corporation
- 1245 -
command operand-data (statement-data)
command identifies the action to be performed.
operand-data represents the objects associated with a storage array that you want to configure or
manage.
statement-data provides the information needed to perform the command.
The syntax for operand-data has the following structure:
(object-type | allobject-types | [qualifier]
(object-type [identifier] {object-type [identifier]} |
object-types [identifier-list]))
An object can be identified in four ways:
Object type – Use when the command is not referencing a specific object.
all parameter prefix – Use when the command is referencing all of the objects of the specified type in
the storage array (for example, allVolumes).
Square brackets – Use when performing a command on a specific object to identify the object (for
example, volume [engineering]).
A list of identifiers – Use to specify a subset of objects. Enclose the object identifiers in square brackets
(for example, volumes [sales engineering marketing]).
A qualifier is required if you want to include additional information to describe the objects.
The object type and the identifiers that are associated with each object type are listed in this table.
Script Command Object Type Identifiers
Object Type Identifier
controller a or b
drive Tray ID and slot ID
replacementDrive Tray ID and slot ID
driveChannel Drive channel identifier
host User label

Object Type Identifier
snapshot Volume user label
storageArray Not applicable
tray Tray ID
volume Volume user label or volume World Wide
Identifier (WWID) (set command only)
volumeCopy Target volume user label and, optionally, the
source volume user label
volumeGroup User label
Valid characters are alphanumeric, a hyphen,
and an underscore.
Statement data is in the form of:
Parameter = value (such as raidLevel=5)
Parameter-name (such as batteryInstallDate)
Operation-name (such as redundancyCheck)
A user-defined entry (such as user label) is called a variable. In the syntax, it is shown in italic (such as
trayID or volumeGroupName).
Synopsis of the Script Commands
Because you can use the script commands to define and manage the different aspects of a storage array
(such as host topology, drive configuration, controller configuration, volume definitions, and volume group
definitions), the actual number of commands is extensive. The commands, however, fall into general
categories that are reused when you apply the commands to the different to configure or maintain a storage
array. The following table lists the general form of the script commands and a definition of each command.
General Form of the Script Commands

1For tray loss protection to work, each drive in a volume group must be in a separate tray. If you set the
trayLossProtect parameter to TRUE and you have selected more than one drive from any one tray, the
storage array returns an error. If you set trayLossProtect parameter to FALSE, the storage array performs
operations, but the volume group that you create might not have tray loss protection.
If you set the trayLossProtect parameter to TRUE, the storage array returns an error if the controller
firmware cannot find drives that will enable the new volume group to have tray loss protection. If you set the
trayLossProtect parameter to FALSE, the storage array performs the operation even if it means that the
volume group might not have tray loss protection.
2In trays that have drawers for holding the drives, drawer loss protection determines whether data on
a volume is accessible or inaccessible if a drawer fails. To help make sure that your data is accessible,
set the drawerLossProtect parameter to TRUE. For drawer loss protection to work, each drive in a
volume group must be in separate drawers. If you have a storage array configuration in which a volume
group spans several trays, you must make sure that the setting for drawer loss protection works with the
setting for tray loss protection. If you set the trayLossProtect parameter to TRUE, you must set the
drawerLossProtect parameter to TRUE. If you set the trayLossProtect parameter to TRUE, and
you set the drawerLossProtect parameter to FALSE, the storage array returns an error message and a
storage array configuration will not be created.
3To determine if a free capacity area exists, run the show volumeGroup command.
4The default drive (drive type) is fibre (Fibre Channel).
The driveType parameter is not required if only one type of drive is in the storage array. If you use the
driveType parameter, you also must use the hotSpareCount parameter and the volumeGroupWidth
parameter. If you do not use the driveType parameter, the configuration defaults to Fibre Channel drives.
5The dataAssurance parameter applies to the drives in a volume group. Using the dataAssurance
parameter, you can specify that protected drives must be selected for a volume group. If you want to set
the dataAssurance parameter to enabled, all of the drives in the volume group must be capable of data
assurance. You cannot have a mix of drives that are capable of data assurance and drives that are not
capable of data assurance in the volume group.
6The volumesPerGroupCount parameter is the number of equal-capacity volumes per volume group.
7The securityType parameter enables you to specify the security setting for a volume group that you are
creating. All of the volumes are also set to the security setting that you choose. Available options for setting
the security setting include:
none – The volume group is not secure.
capable – The volume group is security capable, but security has not been enabled.
enabled – The volume group is security enabled.

NOTE A storage array security key must already be created for the storage array if you want to set
securityType=enabled. (To create a storage array security key, use the create storageArray
securityKey command).
Usage Guidelines
This list provides guidelines for writing script commands on the command line:
You must end all commands with a semicolon (;).
You can enter more than one command on a line, but you must separate each command with a
semicolon (;).
You must separate each base command and its associated primary parameters and secondary
parameters with a space.
The script engine is not case sensitive. You can enter commands by using uppercase letters, lowercase
letters, or mixed-case letters.
Add comments to your scripts to make it easier for you and future users to understand the purpose of the
script commands. (For information about how to add comments, see "Adding Comments to a Script File.")
NOTE While the CLI commands and the script commands are not case sensitive, user labels (such as
for volumes, hosts, or host ports) are case sensitive. If you try to map to an object that is identified by a user
label, you must enter the user label exactly as it is defined, or the CLI commands and the script commands
will fail.
Adding Comments to a Script File
The script engine looks for certain characters or a command to show comments. You can add comments to a
script file in three ways:
1. Add text after two forward slashes (//) as a comment until an end-of-line character is reached. If the
script engine does not find an end-of-line character in the script after processing a comment, an error
message appears, and the script operation is terminated. This error usually occurs when a comment is
placed at the end of a script and you have forgotten to press the Enter key.
// Deletes the existing configuration.
set storageArray resetConfiguration=true;
2. Add text between /* and */ as a comment. If the script engine does not find both a starting comment
notation and an ending comment notation, an error message appears, and the script operation is
terminated.
/* Deletes the existing configuration */
set storageArray resetConfiguration=true;
3. Use the show statement to embed comments in a script file that you want to appear while the script file is
running. Enclose the text that you want to appear by using double quotation marks (“ ”).
show “Deletes the existing configuration”;
set storageArray resetConfiguration=true;

Configuring a Storage Array
This chapter explains how to run script commands from the command line to create a volume from a
collection of drives and to configure a RAID storage array. This chapter assumes that you have a basic
understanding of RAID concepts and terminology. Before you begin to configure your storage array, become
familiar with these concepts:
Controllers
Drives
Hot spares
Volume groups
Volumes
RAID technology
Hosts
Host groups
Host bus adapter (HBA) host ports
Logical unit numbers (LUNs)
Configuring a RAID storage array requires caution and planning to make sure that you define the correct
RAID level and configuration for your storage array. The main purpose in configuring a storage array is to
create volumes, which are addressable by the hosts, from a collection of drives. The commands described in
this chapter enable you to set up and run a RAID storage array. Additional commands are also available to
provide you with more control and flexibility in managing and maintaining your storage array.
NOTE Many of these commands require a thorough understanding of the firmware as well as an
understanding of the network components that need to be mapped. Use the CLI commands and the script
commands with caution.
The sections in this chapter show some, but not all, of the CLI wrapper commands and the script commands.
The commands in this chapter show how you can use the commands to configure a storage array. These
presentations do not describe all possible usage and syntax for the commands. For complete definitions of
the commands, including syntax, parameters, and usage notes, refer to the Command Line Interface and
Script Commands.
This chapter contains examples of CLI command usage and script command usage. The command syntax
that is used in the examples is for a host running a Microsoft operating system. As part of the examples, the
complete C:\ prompt and the DOS path for the commands are shown. Depending on your operating system,
the prompt and path construct will vary.
For most commands, the syntax is the same for all Windows operating systems and UNIX operating systems,
as well as for a script file. Windows operating systems, however, have an additional requirement when
entering names on a command line. On Windows operating systems, you must enclose the name between
two back slashes (\ \) in addition to other delimiters. For example, the following name is used in a command
running under a Windows operating system:
[\”Engineering\”]
For a UNIX operating system, and when used in a script file, the name appears as follows:
[“Engineering”]

Configuration Concepts
When you configure a storage array, you organize drives into a logical structure that provides storage
capacity and data protection so that one or more hosts can safely store data in the storage array. This section
provides definitions of the physical and logical components required to organize the physical disks into a
storage array configuration. This section also describes how the components relate to each other.
Controllers
All storage arrays have one or two controllers. The controllers are circuit-board assemblies that manage data
and communication between the hosts and the storage array. The controller manages the data flow between
the hosts and the drives, keeping track of the logical address of where the data resides. In general, each
controller has a processor for performing control operations, NVSRAM for storing the firmware code that
operates the storage array, and the buses along which the data flows.
The controllers are located in a controller tray or a controller-drive tray. The controller tray or a controller-drive
tray has two positions for controllers: slot A and slot B. The script commands identify each controller by the
slot in which the controller is installed. If controller tray or a controller-drive tray has only one controller, the
controller must be in slot A. A controller tray or a controller-drive tray with two controllers is called a duplex
tray. A controller tray or a controller-drive tray with one controller is called a simplex tray.
Early controller models FC1250 and FC1275 used minihubs; two connected to each controller. When viewed
from the rear of the controller tray, the host-side minihubs are numbered from left-to-right a1, b1, a2, and
b2. The script commands identify the host channels by using these identifiers. Minihubs also support the
drive-side, where each minihub represents a single channel to the drives. When viewed from the rear of the
controller tray, the drive minihubs are numbered from left to right 4, 3, 2, and 1. The script commands use
these numbers to identify the drive channels.
Controller models SAT2700 and SHV2600 are used in an early controller-drive tray that has a slot where
either a controller or an environmental services monitor (ESM) can be used. When an ESM is used, the tray is
called a drive tray.
Controllers manage the interface by running controller firmware to transmit and receive commands between
the hosts and the drives. Host bus adapters facilitate the communication through whichever interface is
selected. Typically, two host bus adapters and two paths are used to optimize redundancy.
The controller-drive trays and controller trays incorporate all host connections and drive tray connections
into each controller. The host ports must be identified in your command statements to let you complete their
network configurations.
The more recent models of controllers do not use minihubs. These controllers have host ports that are
integrated into the controller circuit boards or auxiliary circuit boards that are directly connected to the
controller circuit boards.
The following table lists the controller-drive trays that do not use minihubs, the type of host port, and the
number of host ports.

The four iSCSI host connections are
used with eight Fibre Channel host
connections.
The AM1333 controller-drive tray has three host ports that are numbered from left to right: host port 1, host
port 2, and host port 3 as seen from the rear of the controller-drive tray.
The AM1532 and AM1932 controller-drive trays have two host ports on each controller, which are numbered
from left to right: host port 1 and host port 2 as seen from the rear of the controller-drive tray.
The host ports on the CDE3994 controller-drive tray are numbered from left-to-right on controller B as Ch 1,
Ch 2, Ch 3, and Ch 4. Controller A, which is installed upside-down in the controller-drive tray, is numbered
from right-to-left in the same sequence.
The controller in the CE6998 controller tray can have up to four host channels with one port for each channel;
up to two drive channels with two ports per channel (for a total of four drive ports); and up to two Ethernet
ports. In the CE6998 controller tray, the controllers are stacked one above the other. The top controller is A.
The bottom controller is B.
For controller A, the host channel identifiers are a1, a2, a3, and a4, and the host bus adapter (HBA) host
ports are labeled 1, 2, 3, and 4. For controller B, the host channel identifiers are b1, b2, b3, and b4, and the
HBA host ports are labeled 1, 2, 3, and 4.
Controller A has drive channels 1 and 2. Drive ports labeled 3 and 4 connect to drive channel 1. Drive ports
labeled 1 and 2 connect to Drive Channel 2. Controller B has drive channels 3 and 4. Drive ports labeled
1 and 2 connect to drive channel 3. Drive ports labeled 3 and 4 connect to drive channel 4. Each Ethernet
port on a controller can have a unique IP address; however, both Ethernet ports share the same gateway IP
address, subnet mask, and remote login settings.

Each of the two controllers in the CE7900 controller tray can have two host cards with four host ports on
each card. Some CE7900 controller trays can have controllers with only one host card each. Controller A is
inverted from controller B, which means that its host channels are upside-down.
Drives
The drives store the data that is sent to the storage array. The drives are mounted in either a controller-
drive tray or a drive tray. The controller-drive tray has drives and controllers in one tray. A drive tray has
only drives, and is connected to a controller through an environmental services monitor (ESM). In addition to
the drives and ESMs, the drive tray contains power supplies an fans. These components support drive tray
operation and can be maintained through the CLI.
Drives are located in a storage array by tray ID and slot ID. Tray ID values are 0 to 99. In older trays, tray ID
values are set during installation by switches on the rear of the trays. In newer trays, tray ID values are set
automatically when the power is applied.
The slot ID is the drive position in the drive tray. A drive tray can contain 12, 14, 16, 24, or 60 drives. In drive
trays with fewer than 60 drives, slot ID values range from 1 to 32. In drive trays with 60 drives, slot ID values
are defined by the drawer number and the position of the drive in the drawer. The drawer numbers range from
1 to 5, counting from top to bottom. The position of each drive in a drawer is shown in the following figure.
Drive Drawer with Drives
The total number of drives in a storage array depends on the model of the controller tray or controller-drive
tray and the capacity of the drives. The following table lists, by controller tray or controller-drive tray model
and drive tray capacity, the maximum number of drives in a storage array.

Hot Spare Drives
A hot spare is a drive that acts as a standby in the event that a drive containing data fails. The hot spare is
a drive that has not been assigned to a particular volume group and, as such, can be used in any volume
group. You can use the hot spare feature with RAID Level 1, RAID Level 3, RAID Level 5, or RAID Level 6.
If a drive in a volume group fails, the controllers automatically replace the failed drive with a hot spare. The
controllers use redundancy data to reconstruct the data from the failed drive onto the hot spare. To be most
effective, the drive that you assign as a hot spare must have a capacity equal to or greater than the capacity
of the largest drive in the storage array. The hot spare must be the same type of drive as the drive that failed
(for example, a Serial Advanced Technology Attachment [SATA] hot spare cannot replace a Fibre Channel
hot spare).
You can assign drives to act as hot spares manually or have the script commands automatically assign hot
spares. If you manually assign a drive to be a hot spare, you must identify the drive by tray ID and slot ID.
When you let the script commands automatically assign hot spares, you must enter the number of hot spares
that you want in the storage array.

SafeStore Drive Security with Full Disk Encryption
SafeStore Drive Security is a premium feature that prevents unauthorized access to the data on a drive that is
physically removed from the storage array. Controllers in the storage array have a security key. Secure drives
provide access to data only through a controller that has the correct security key. SafeStore Drive Security is
a premium feature of the storage management software and must be enabled either by you or your storage
vendor.
The SafeStore Drive Security premium feature requires security capable drives. A security capable drive
encrypts data during writes and decrypts data during reads. Each security capable drive has a unique drive
encryption key.
When you create a secure volume group from security capable drives, the drives in that volume group
become security enabled. When a security capable drive has been security enabled, the drive requires the
correct security key from a controller to read or write the data. All of the drives and controllers in a storage
array share the same security key. The shared security key provides read and write access to the drives,
while the drive encryption key on each drive is used to encrypt the data. A security capable drive works like
any other drive until it is security enabled.
Whenever the power is turned off and turned on again, all of the security-enabled drives change to a security
locked state. In this state, the data is inaccessible until the correct security key is provided by a controller.
You can view the SafeStore Drive Security status of any drive in the storage array from the Drive Properties
dialog. The drive can have one of these capabilities:
Security Capable
Secure – Security enabled or disabled
Read/Write Accessible – Security locked or unlocked
You can view the SafeStore Drive Security status of any volume group in the storage array by using the show
volume group command. The volume group can have one of these capabilities:
Security Capable
Secure
The following table shows how to interpret the security properties status of a volume group.
Volume Group Security Properties
Security Capable – yes Security Capable – no
Secure – yes The volume group is composed of
all full disk encryption (FDE) drives
and is in a Secure state.
Not applicable. Only FDE
drives can be in a Secure
state.
Secure – no The volume group is composed
of all FDE drives and is in a Non-
Secure state.
The volume group is not
entirely composed of FDE
drives.
You can erase security-enabled drives so that you can reuse the drives in another volume group or in another
storage array. Use the start secure erase command to completely erase any data on a security-enabled
drive. Using the start secure erase command results in the loss of all of the data on a drive, and is
irreversible. You can never recover the data.
SANtricity_10.77 February 2011

The storage array password protects a storage array from potentially destructive operations by unauthorized
users. The storage array password is independent from the SafeStore Drive Security premium feature and
should not be confused with the pass phrase that is used to protect copies of a security key. However, it is
good practice to set a storage array password before you create, change, or save a security key or unlock
secure drives.
Commands for FDE Drives
You can use these commands to enable security in the FDE drives and manage the drives.
activate hostPort
activate iscsiInitiator
create volume – Automatic drive select
create volume – Free extent based select
create volume – Manual drive select
create storageArray securityKey

import storageArray securityKey
set controller
set storageArray securityKey
show drive
start secure erase
Volume Groups
A volume group is a set of drives that are logically grouped together by the controllers in a storage array.
After you create a volume group, you can create one or more volumes in the volume group. A volume group
is identified by a sequence number that is defined by the controller firmware when you created the volume
group.
NOTE Some storage arrays permit different drive types in the same tray; however, you cannot have a
combination of different drives in the same volume group.
To create a volume group, you must define the capacity and the RAID level.
Capacity is the size of the volume group. Capacity is determined by the number of drives that you assign to
the volume group. You can use only unassigned drives to create a volume group. (In this programming guide,
the storage space on unassigned drives constitutes the unconfigured capacity of a storage array.)
Free capacity is a contiguous region of unassigned capacity in a designated volume group. Before you create
a new volume in a volume group, you need to know the free capacity space so that you can determine the
size of the volume.

The RAID level is the level of data protection that you want to define for your storage array. The RAID level
that you choose affects storage capacity. When you configure your storage array, you must consider this
compromise between data protection and storage capacity. In general, the more protection that you need, the
less storage capacity is available in your storage array.
The following table lists the minimum number of drives and the maximum number of drives that you can use
in a volume group based on the RAID level that you want to assign to the volume group.

Drives
Redundancy
0 1 All None
1 1 All Mirrored
pairs
3 3 30 1 drive
5 3 30 1 drive
6 5 30 2 drives
You can determine the size of the volume group by multiplying the maximum number of drives in the volume
group by the capacity of the smallest drive in the volume group.
Volumes
A volume is a logical component (object) that is the basic structure that is created on the storage array to
store data. A volume is a contiguous subsection of a volume group that is configured to meet application
needs for data availability and I/O performance. The storage management software administers a volume as
if the volume is one “drive” for data storage. Volumes are identified by names or labels that users choose. The
volume names can be any combination of alphanumeric characters, hyphens (-), and underscores (_). The
maximum length of a volume name is 30 characters.
The script commands support the following types of volumes:
Standard volume – A logical structure that is the principal type of volume for data storage. A standard
volume is the most common type of volume in a storage array.
Access volume – A factory-configured volume in a storage area network (SAN) environment that is used
for communication between the storage management software and the storage array controller. The
access volume uses a logical unit number (LUN) address and consumes 20 MB of storage space. The 20
MB of access volume storage space is not available for data storage.
NOTE Use the access volume only for in-band-managed storage arrays.
Snapshot volume – A logical point-in-time image of another volume. A snapshot volume is the logical
equivalent of a complete physical copy; however, it is not an actual, physical copy. Instead, the firmware
tracks only the data blocks that are overwritten and copies those blocks to a snapshot repository volume.
Snapshot repository volume – A special volume in the storage array that is created as a resource for
a snapshot volume. A snapshot repository volume contains snapshot data and copy-on-write data for a
particular snapshot volume.
SANtricity_10.77 February 2011
LSI Corporation
- 1265 -
Base volume – A standard volume from which you create a snapshot volume. The term “base volume” is
used only to show the relationship between a standard volume from which you are taking the point-in-time
image and a snapshot volume.
Primary volume – A standard volume in a Remote Volume Mirroring relationship. The primary volume
accepts host data transfers and stores application data. When you first create the mirror relationship, data
from the primary volume is copied in its entirety to the associated secondary volume.
Secondary volume – A standard volume in a Remote Volume Mirroring relationship that maintains
a mirror (or copy) of the data from its associated primary volume. The secondary volume remains
unavailable to host applications while mirroring is underway. In the event of a disaster or a catastrophic
failure of the primary site, a system administrator can promote the secondary volume to a primary role.
Mirror repository volume – A special volume in a Remote Volume Mirroring configuration that is created
as a resource for each controller in both the local storage array and the remote storage array. The
controller stores mirroring information on this volume, including information about remote writes that are
not yet complete. A controller can use this information to recover from controller resets and accidental
power shutdown of the storage arrays.
NOTE Snapshot Volume and Remote Volume Mirroring are premium features that you must activate
before you can use them. For more information about snapshot volumes, see “Using the Snapshot Premium
Feature.” For more information about Remote Volume Mirroring, see “Using the Remote Volume Mirroring
Premium Feature.”
The number and capacity of the volumes in your storage array depends on the type of controller in the
storage array. The following table lists the maximum number of volumes in a storage array that each
controller model supports.

NOTE The maximum volume size is limited by the size of the drives and the configuration of the
storage array. The last 512 MB on each drive is reserved for storage array configuration database and
potential future expansion. For practical considerations, you want to constrain the maximum volume size so
that drive replacement and volume reconstruction does not take an excessive amount of time.

RAID Levels
The RAID level defines a storage architecture in which the storage capacity on the drives in a volume group
is separated into two parts: part of the capacity stores the user data, and the remainder stores redundant or
parity information about the user data. The RAID level that you choose determines how user data is written
to and retrieved from the drives. Using the script commands, you can define five RAID levels: RAID Level 0,
RAID Level 1, RAID Level 3, RAID Level 5, and RAID Level 6. Each level provides different performance and
protection features.
RAID Level 0 provides the fastest storage access but does not provide any redundant information about
the stored data. RAID Level 1, RAID Level 3, RAID Level 5, and RAID Level 6 write redundancy information
to the drives to provide fault tolerance. The redundancy information might be a copy of the data or an
error-correcting code that is derived from the data. In RAID Level 1, RAID Level 3, RAID Level 5, or RAID
Level 6 configurations, if a drive fails, the redundancy information can be used to reconstruct the lost data.
Regardless of the RAID level that you choose, you can configure only one RAID level across each volume
group. All redundancy information for a volume group is stored within the volume group. The following table
lists the RAID levels and describes the configuration capabilities of each level.
RAID Level Configurations
RAID
Level Configuration
0Non-redundant striping mode – Use this level for high-performance needs.
RAID Level 0 does not provide any data redundancy. RAID Level 0 stripes
data across all of the drives in the volume group. If a single drive fails, all
of the associated volumes fail and all data is lost. RAID Level 0 is suited for
noncritical data. It is not recommended for high-availability needs.
1Striping mirroring mode – RAID Level 1 uses drive mirroring to create an
exact copy from one drive to another drive. A minimum of two drives are
required; one for the user data, and one for the mirrored data. RAID Level 1
offers high performance and the best data availability.
Data is written to two drives simultaneously. If one drive in a drive pair fails,
the system can instantly switch to the other drive without any loss of data or
service. Only half of the drives in the volume group are available for user data.
If a single drive fails in a RAID Level 1 volume group, all of the associated
volumes become degraded, but the mirror drive provides access to the data.
RAID Level 1 can survive multiple drive failures as long as no more than
one failure occurs per mirrored pair. If a drive pair fails, all of the associated
volumes fail, and all data is lost.
3High-bandwidth mode – RAID Level 3 stripes both user data and redundancy
data (in the form of parity) across the drives. The equivalent of the capacity of
one drive is used for the redundancy data. RAID Level 3 works well for large
data transfers in applications, such as multimedia or medical imaging, that
write and read large sequential chunks of data.
If a single drive fails in a RAID Level 3 volume group, all of the associated
volumes become degraded, but the redundancy data lets the data be
reconstructed. If two or more drives fail, all of the associated volumes fail, and
all data is lost.

RAID
Level Configuration
5High I/O mode – RAID Level 5 stripes both user data and redundancy data
(in the form of parity) across the drives. The equivalent of the capacity of one
drive is used for the redundancy data. RAID Level 5 works well for multiuser
environments, such as databases or file system storage, where typical I/O size
is small, and a high proportion of read activity exists.
If a single drive fails in a RAID Level 5 volume group, all of the associated
volumes become degraded, and the redundancy data permits the data to be
reconstructed. If two or more drives fail, all of the associated volumes fail, and
all data is lost.
6Data protection or continuous access mode – RAID Level 6 stripes both
user data and redundancy data (in the form of parity) across the drives.
A minimum of five drives are required for a RAID Level 6 volume group.
The equivalent capacity of two drives is used for the redundancy data. Two
different algorithms calculate redundancy data, which are in the form of both a
P parity and a Q parity.
RAID Level 6 works well for larger drive sizes. Recovery from a second drive
failure in the same volume group is possible. If two drives fail in a RAID Level
6 volume group, all of the associated volumes become degraded, but the
redundancy data permits the data to be reconstructed. If three or more drives
fail, all of the associated volumes fail, and all data is lost.
NOTE RAID Level 6 is only available to those controllers that are capable of supporting the P+Q
calculation. The model CE6998 controller does not support RAID Level 6. The CDE2600, CDE3992,
CDE3994, CDE4900, and CE7900, controllers support RAID Level 6. A premium feature key enables
customers to use RAID Level 6 and to use dynamic RAID-level migration. Refer to the "Set Volume Group"
command in Command Line Interface and Script Commands for Version 10.75 for information explaining how
to set your volume group to RAID Level 6.
Hosts
A host is a computer that is attached to the storage array for accessing the volumes in the storage array.
The host is attached to the storage array through HBA host ports, which are connectors on host bus adapter
circuit boards. You can define specific volume-to-LUN mappings to an individual host or assign the host to
a host group that shares access to one or more volumes. Hosts are identified by names or labels that users
choose. The host name can be any combination of alphanumeric characters, hyphens, and underscores. The
maximum length of the host name is 30 characters.
In addition to a host name, some script commands require you to identify a host by its A host type identifies
the operating system under which the host is running (such as Windows, Solaris, or Linux). Specifying the
host type lets the controllers in the storage array adapt their behavior (such as LUN reporting and error
conditions) to the operating system of the host that is sending the information. Host types are identified by a
label or an index number that is generated by the controller firmware.
Host Groups
A host group is a topological element that you can define if you want to designate a collection of hosts that
will share access to the same volumes. A host group is a logical entity. Host groups are identified by names
or labels that users choose. The host group name can be any combination of alphanumeric characters with a
maximum length of 30 characters.

Host Bus Adapter Host Ports
A host bus adapter (HBA) provides the physical connection from the host to the storage array. The host port
is a physical connector on an HBA. The HBA is a circuit board that is installed in the host. The HBA can have
one or more host ports. Each host port is identified by a unique, 16-byte World Wide Identifier (WWID). If the
HBA has more than one host port, each host port has a unique ID.
When you first turn on the power to a storage array, the storage management software automatically detects
the HBA host ports. Initially, all detected host ports belong to a default group. You can use script commands
to identify the WWIDs on a storage array and, if you choose, change them. If you move an HBA host port, you
must remap any volume-to-LUN mappings. Access to your data is lost until you remap the volumes.
The maximum number of HBA host ports that you can logically define for your storage array depends on the
type of controller in the storage array. The following table lists the maximum number of HBA host ports that
you can define.
Maximum Number of HBA Host Ports per Controller
Controller Models Maximum Number of Host Ports
1331, 1333, 1532,
1932 256
CDE2600 256
CDE3992 or CDE3994 256
CDE4900 256
CE6998 512
CE7900 1024
Logical Unit Numbers
In the context of the CLI commands and the script commands, a logical unit number (LUN) is a unique value
that identifies the volumes in a storage array. The hosts identify the volumes that they want to access using
the LUN values. When you create a volume, the firmware assigns the LUN values, or you can assign LUN
values when you enable the SANshare Storage Partitioning premium feature. A volume can have only one
LUN and can be mapped to only one host or host group. Each host has unique addressing capability. That is,
when more than one host accesses a storage array, each host might use the same LUN to access different
volumes. The LUNs might be the same, but the volumes are different. If you are mapping to a host group, the
LUN that you specify must be available on every host in the host group.
Configuring a Storage Array
When you configure a storage array, you want to maximize the data availability by making sure that the data
is quickly accessible while maintaining the highest level of data protection possible. The speed by which a
host can access data is affected by these items:
The RAID level for the volume group
The settings for the segment size and the cache size
Whether the cache read prefetch capability is turned on or turned off
SANtricity_10.77 February 2011

Data protection is determined by the RAID level, hardware redundancy (such as global hot spares), and
software redundancy (such as the Remote Volume Mirroring premium feature and the Snapshot Volume
premium feature).
In general, you configure a storage array by defining a volume group and its associated RAID level, defining
the volumes, and defining which hosts have access to the volumes. This section explains how to use the
script commands to perform the general steps to create a configuration from an array of drives.
Determining What Is on Your Storage Array
Even when you create a configuration on a storage array that has never been configured, you still need
to determine the hardware features and software features that are to be included with the storage array.
When you configure a storage array that has an existing configuration, you must make sure that your
new configuration does not inadvertently alter the existing configuration, unless you are reconfiguring the
entire storage array. For example, consider the case where you want to create a new volume group on
unassigned drives. Before you create a new volume group, you must determine which drives are available.
The commands that are described in this section help you to determine the components and the features in
your storage array.
The command that returns general information about the storage array is the show storageArray
command. This command returns information about the components and properties of your storage array,
including these items:
A detailed profile of the components and features in the storage array
The age of the battery
The default host type (which is the current host type)
Other host types that you can select
The hot spare locations
The identifiers for enabled premium features
The logical component profiles and the physical component profiles
The time to which both controllers are set
The controller that currently owns each volume in the storage array
To return the most information about the storage array, run the show storageArray command with the
profile parameter. This example shows the complete CLI command and script command running on a
Windows operating system:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show storageArray profile;”
This example identifies the storage array by the IP addresses 123.45.67.88123.45.67.89. These
addresses are the IP addresses of the controllers in the storage array. You can also identify the storage array
by name.
The show storageArray profile command returns detailed information about the storage array. The
information appears in several display screens. You might need to increase the size of your display buffer to
see all of the information. Because this information is so detailed, you might want to save the output to a file.
To save the output to a file, enter the command as shown in this example:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show storageArray profile;” -o
c:\folder\storagearrayprofile.txt
SANtricity_10.77 February 2011
LSI Corporation
- 1270 -
In this example, the name folder is the folder in which you choose to place the profile file, and
storagearrayprofile.txt is the name of the file. You can choose any folder and any file name.
ATTENTION Possible loss of data – When you write information to a file, the script engine does not
check to determine if the file name already exists. If you choose the name of a file that already exists, the
script engine writes over the information in the file without warning.
The topic "Examples of Information Returned by the Show Commands," shows the type of information
returned. When you save the information to a file, you can use the information as a record of your
configuration and as an aid during recovery.
To return a brief list of the storage array features and components, use the summary parameter. The
command looks like this example:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show storageArray summary;”
Following is the type of information that is returned by the show storageArray command with the
summary parameter.

The show commands return information about the specific components of a storage array. The
information returned by each of the show commands is the same as the information returned by the show
storageArray profile command, but the information is constrained to the specific component. Following
is a list of the show commands.

Clearing the Configuration
If you want to create a completely new configuration on a storage array that already has an existing
configuration, use the clear storageArray configuration command. This command deletes all of the
existing configuration information, including all of the volume groups, volumes, and hot spare definitions from
the controller memory.
ATTENTION Possible damage to the storage array configuration – As soon as you run this
command, the existing storage array configuration is deleted.
The command has this form:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “clear storageArray configuration;”
This command has two parameters that you can use to limit the amount of configuration information removed:
all – Removes the entire configuration of the storage array, including security information and
identification information. Removing all of the configuration information returns the storage array to its
initial state.
volumeGroups – Removes the volume configuration and the volume group configuration, but leaves the
rest of the configuration intact.

If you want to create new volume groups and volumes within the storage array, you can use the clear
storageArray configuration command with the volumeGroups parameter to remove existing volume
groups in a pre-existing configuration. This action destroys the pre-existing configuration. Use the clear
storageArray configuration command only when you create a new configuration.
Using the Auto Configure Command
The autoConfigure storageArray command creates the volume groups on a storage array, the
volumes in the volume groups, and the hot spares for the storage array. When you use the autoConfigure
storageArray command, you define these parameters:
The type of drives (Fibre, SATA, or SAS)
The RAID level
The number of drives in a volume group
The number of volume groups
The number of volumes in each volume group
The number of hot spares
The size of each segment on the drives
A read ahead multiplier
After you define these parameters, the SANtricity ES Storage Manager software creates the volume groups,
the volumes, and the hot spares. The controllers assign volume group numbers and volume numbers as they
are created. After the SANtricity ES Storage Manager software creates the initial configuration, you can use
the set volume command to define volume labels.
Before you run the autoConfigure storageArray command, run the show storageArray
autoConfigure command. The latter command returns a list of parameter values that the SANtricity
ES Storage Manager software uses to automatically create a storage array. If you would like to change
any of the parameter values, you can do so by entering new values for the parameters when you run the
autoConfigure storageArray command. If you are satisfied with the parameter values that the show
storageArray autoConfiguration command returns, run the autoConfigure storageArray
command without new parameter values.
The autoConfigure storageArray command has this form:
When you use the autoConfigure storageArray command, two symbol functions
(getAutoConfigCandidates and createAutoConfig) are used that let the client retrieve default
settings for the various automatic configuration parameters, change the settings, query what the results
of those changes would be and, finally, apply the desired parameters to create a configuration. The
configurability portion of this feature provides enhancements to the automatic volume group creation
algorithms, which produce volume groups with improved performance and more information about drive and
volume attributes so the user can make better choices when configuring volumes manually.
The volumeGroupWidth parameter defines the number of unassigned drives that you want to use for each
new volume group.
The volumeGroupCount parameter defines the number of new volume groups that you want in the storage
array.
The volumesPerGroupCount parameter defines the number of volumes that you want in each volume
group.
SANtricity_10.77 February 2011
LSI Corporation
- 1273 -
The hotSpareCount parameter defines the number of hot spares that you want in each volume group.
The segmentSize parameter defines the amount of data, in KB, that the controller writes on a single drive
in a volume before writing data on the next drive. The smallest units of storage are data blocks. A data block
stores 512 bytes of data. The size of a segment determines how many data blocks that it contains. An 8-KB
segment holds 16 data blocks. A 64-KB segment holds 128 data blocks.
IMPORTANT For optimal performance in a multiuser database or file system storage environment, set
the segment size to minimize the number of drives that are needed to satisfy an I/O request.
Using a single drive for a single request leaves other drives available to simultaneously service other
requests. Valid segment size values are 8, 16, 32, 64, 128, 256, and 512.
NOTE If you set the cache block size to 16, you cannot create a volume with a segment size of 8.
If the volume is for a single user with large I/O requests (such as multimedia), performance is maximized
when a single I/O request can be serviced with a single data stripe. A data stripe is the segment size
multiplied by the number of drives in the volume group that are used for data storage. In this environment,
multiple drives are used for the same request, but each drive is accessed only once.
The cacheReadPrefetch parameter turns on or turns off the ability of the controller to read additional data
blocks into the cache. When you turn on cache read prefetch, the controller copies additional data blocks
into the cache while it is reading requested data blocks from a drive into the cache. This action increases
the chance that a future request for data can be fulfilled from the cache, which improves the speed with
which data is accessed. The number of additional data blocks that the controller reads into the cache is
determined by the configuration settings for the storage array that you use. Cache read prefetch is important
for applications that use sequential I/O, such as multimedia applications.
Valid values for the cacheReadPrefetch parameter are TRUE or FALSE. If you want to turn on cache read
prefetch, set the cacheReadPrefetch parameter to TRUE. If you want to turn off cache read prefetch, set
the cacheReadPrefetch parameter to FALSE.
The following table lists the default values for the segment size and cache read prefetch settings for different
storage array uses.
Default Values for Segment Size and Cache Read Prefetch
Storage Array Use Segment Size (KB) Cache Read
Prefetch
File system 128 TRUE
Database 128 TRUE
Multimedia 256 TRUE
Use the securityType parameter when you have security#capable drives that can support the SafeStore
Drive Security premium feature. This parameter enables you to specify the security level when you create the
volume group that uses the security#capable drives. The settings for the securityType parameter are:
none – The volume group and volumes are not secure.
capable – The volume group and volumes are capable of having security set, but security has not been
enabled.
SANtricity_10.77 February 2011
LSI Corporation
- 1274 -
enabled – The volume group and volumes have security enabled.
After you have finished creating the volume groups and the volumes by using the autoConfigure
storageArray command, you can further define the properties of the volumes in a configuration by using
the set volume command.
Example of the Auto Configuration Command
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “autoConfigure storageArray driveType=fibre
raidLevel=5 volumeGroupWidth=8 volumeGroupCount=3
volumesPerGroupCount=4 hotSpareCount=2
segmentSize=8 cacheReadPrefetch=TRUE;”
The command in this example creates a storage array configuration by using Fibre Channel drives set to
RAID Level 5. Three volume groups are created, and each volume group consists of eight drives, which are
configured into four volumes. The storage array has two hot spares. The segment size for each volume is 8
KB. The cache read prefetch is turned on, which causes additional data blocks to be written into the cache.
Using the Create Volume Command
Use the create volume command to create new storage array volumes in three ways:
Create a new volume while simultaneously creating a new volume group to which you assign the drives
Create a new volume while simultaneously creating a new volume group to which the storage
management software assigns the drives
Create a new volume in an existing volume group
You must have unassigned drives in the volume group. You do not need to assign the entire capacity of the
volume group to a volume.
Creating Volumes with User-Assigned Drives
When you create a new volume and assign the drives you want to use, the storage management software
creates a new volume group. The controller firmware assigns a volume group number to the new volume
group. The command has this form:
create volume drives=(trayID1, slotID1... trayIDn, slotIDn)
raidLevel=(0 | 1 | 3 | 5 | 6) userLabel=”volumeName”
[volumeGroup=[volumeGroupName]
capacity=volumeCapacity owner=(a | b)
cacheReadPrefetch=(TRUE | FALSE)
segmentSize=segmentSizeValue
trayLossProtect=(TRUE | FALSE)]
NOTE The capacity parameter, the owner parameter, the cacheReadPrefetch parameter, the
segmentSize parameter, the trayLossProtect parameter, the drawerLossProtect parameter, the
dssPreAllocate parameter, and the securityType parameter are optional parameters (indicated by
the placement inside the square brackets). You can use one or all of the optional parameters as needed to
define your configuration. If you choose not to use any of the optional parameters, the default values of the
parameters are used for your configuration.
SANtricity_10.77 February 2011
LSI Corporation
- 1275 -
The userLabel parameter is the name that you want to give to the volume. The volume name can be any
combination of alphanumeric characters, hyphens, and underscores. The maximum length of the volume
name is 30 characters. You must enclose the volume name with double quotation marks (“ ”).
The drives parameter is a list of the drives that you want to use for the volume group. Enter the tray ID
and the slot ID of each drive that you want to use. Enclose the list in parentheses, separate the tray ID value
and the slot ID value of a drive with a comma, and separate each tray ID and slot ID pair with a space. This
example shows you how to enter tray ID values and slot ID values:
(1,1 1,2 1,3 1,4 1,5)
The capacity parameter defines the size of the volume. You do not need to assign the entire capacity of the
drives to the volume. Later, you can assign any unused space to another volume.
The owner parameter defines the controller to which you want to assign the volume. If you do not specify a
controller, the controller firmware determines the volume owner.
The cacheReadPrefetch parameter and the segmentSize parameter are the same as those described for
the autoConfigure storageArray command.
The trayLossProtect parameter turns on or turns off tray loss protection for the volume group. (For a
description of how tray loss protection works, see the topic “Tray Loss Protection.” )
Example of Creating Volumes with User-Assigned Drives
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create volume drives=(1,1 1,2 1,3 2,1 2,2 2,3)
raidLevel=5 userLabel=\”Engineering_1\” capacity=20GB
owner=a cacheReadPrefetch=TRUE segmentSize=128;”
The command in this example automatically creates a new volume group and a volume with the name
Engineering_1. The volume group uses RAID Level 5. The command uses six drives to construct the volume
group. The capacity of the volume will be 20 GB, which is distributed across all six drives. If each drive has a
capacity of 73 GB, the total capacity of all the assigned disks is 438 GB.
73 GB x 6 drives = 438 GB
Because only 20 GB is assigned to the volume, 418 GB remains available (as unconfigured capacity) for
other volumes that a user can add to this volume group later.
438 GB - 20 GB volume group size = 418 GB
Cache read prefetch is turned on, which causes additional data blocks to be written into the cache. The
segment size for each volume is 128 KB. Tray loss protection is set to TRUE, which prevents any operation to
drives in the drive tray if the drive tray fails. Hot spares are not created for this new volume group. You must
create hot spares after you run this command.
Creating Volumes with Software-Assigned Drives
If you choose to let the storage management software assign the drives when you create the volume, you
need only to specify the number of drives that you want to use. The storage management software then
assigns the drives. The controller firmware assigns a volume group number to the new volume group. To
manually create volume groups and volumes, use the create volume command:
create volume driveCount=numberOfDrives
raidLevel=(0 | 1 | 3 | 5 | 6) userLabel=volumeName
SANtricity_10.77 February 2011
LSI Corporation
- 1276 -
[driveType=(fibre | SATA | SAS | PATA)]
[capacity=volumeCapacity | owner=(a | b) |
cacheReadPrefetch=(TRUE | FALSE) |
segmentSize=segmentSizeValue]
[trayLossProtect=(TRUE | FALSE)]
This command is similar to the previous create volume command in which users assign the drives. The
difference between this command and the previous one is that this version of the command requires only the
number and the type of drives you want to use in the volume group. You do not need to enter a list of drives.
All of the other parameters are the same. Tray loss protection is performed differently when the storage
management software assigns the drives than when a user assigns the drives. (For a description of the
difference, see the topic “Tray Loss Protection.”)
Example of Creating Volumes with Software-Assigned Drives
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create volume driveCount=6 raidLevel=5
userLabel=\”Engineering_1\”
capacity=20GB owner=a cacheReadPrefetch=TRUE segmentSize=128;”
The command in this example creates the same volume as the example for the previous create volume
command in which a user assigns the drives. The difference is that a user does not know which drives are
assigned to this volume group.
Creating Volumes in an Existing Volume Group
If you want to add a new volume to an existing volume group, use this command:
create volume volumeGroup=volumeGroupNumber
userLabel=volumeName
[freeCapacityArea=freeCapacityIndexNumber |
capacity=volumeCapacity | owner=(a | b) |
cacheReadPrefetch=(TRUE | FALSE) |
segmentSize=segmentSizeValue]
NOTE Parameters wrapped in square brackets or curly brackets are optional. You can use one or all of
the optional parameters as needed to define your configuration. If you choose not to use any of the optional
parameters, the default values of the parameter are provided for your configuration.
The volumeGroup parameter is the number of the volume group in which you want to create a new volume.
If you do not know the volume group numbers on the storage array, you can use the show allVolumes
summary command to get a list of the volumes and the volume groups to which the volumes belong.
The userLabel parameter is the name that you want to give to the volume. The volume name can be any
combination of alphanumeric characters, hyphens, and underscores. The maximum length of the volume
name is 30 characters. You must enclose the volume name with double quotation marks (“ ”).
The freeCapacityArea parameter defines the free capacity area to use for the volume. If a volume group
has several free capacity areas, you can use this parameter to identify which free capacity area to use for
volume creation. You do not have to assign the entire capacity of the drives to the volume. Later, you can
assign any unused space to another volume.

The usage of the capacity parameter, the owner parameter, the cacheReadPrefetch parameter, and
the segmentSize parameter is the same as described in the previous examples of the create volume
command.
Tray Loss Protection
The trayLossProtect parameter is a boolean switch that you set to turn on or turn off tray loss protection.
For tray loss protection to work, each drive in a volume group must be on a separate tray. The way in which
tray loss protection works depends on the method that you choose to assign the drives for a volume group.
When you assign the drives, if you set trayLossProtect=TRUE and have selected more than one drive
from any one tray, the storage array returns an error. If you set trayLossProtect=FALSE, the storage
array performs operations, but the volume group that you create does not have tray loss protection.
When the controller firmware assigns the drives, if trayLossProtect=TRUE, the storage array posts an
error if the controller firmware cannot provide drives that result in the new volume group having tray loss
protection. If trayLossProtect=FALSE, the storage array performs the operation even if it means that the
volume group might not have tray loss protection.
Tray loss protection is not valid when creating volumes on existing volume groups.
Modifying Your Configuration
For most configurations, after you have created your initial configuration by using the autoConfigure
storageArray command or the create volume command, you must modify the properties of your
configuration to make sure that it performs to meet the requirements for data storage. Use the set
commands to modify a storage array configuration. This section describes how to modify these properties:
The controller clocks
The storage array password
The storage array host type
The storage array cache
The global hot spares
Setting the Controller Clocks
To synchronize the clocks on the controllers with the host, use the set storageArray time command.
Run this command to make sure that event time stamps that are written by the controllers to the Event
Log match the event time stamps that are written to the host log files. The controllers stay available during
synchronization. This example shows the command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set storageArray time;”
Setting the Storage Array Password
Use the set storageArray command to define a password for a storage array. The command has this
form:
set storageArray password=”password”
The password parameter defines a password for the storage array. Passwords provide added security to a
storage array to help reduce the possibility of implementing destructive commands.
SANtricity_10.77 February 2011
LSI Corporation
- 1278 -
ATTENTION Possible data corruption or data loss – Implementing destructive commands can
cause serious damage, including data loss.
Unless you define a password for the storage array, you can run all of the script commands. A password
protects the storage array from any command that the controllers consider destructive. A destructive
command is any command that can change the state of the storage array, such as volume creation; cache
modification; or reset, delete, rename, or change commands.
If you have more than one storage array in a storage configuration, each storage array has a separate
password. Passwords can have a maximum length of 30 alphanumeric characters. You must enclose
the password in double quotation marks (“ ”). This example shows how to use the set storageArray
command to define a password:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set storageArray password=”1a2b3c4d5e”;”
Setting the Storage Array Host Type
Use the set storageArray command to define the default host type. The command has this form:
set storageArray defaultHostType=(hostTypeName | hostTypeIdentifier)
The defaultHostType parameter defines how the controllers in the storage array will communicate with the
operating system on undefined hosts that are connected to the storage array SAN. This parameter defines
the host type only for data I/O activities of the storage array. This parameter does not define the host type for
the management station. The operating system can be Windows, Linux, or Solaris.
For example, if you set the defaultHostType parameter to Linux, the controller communicates with any
undefined host if the undefined host is running a Linux operating system. Typically, you would need to change
the host type only when you are setting up the storage array. The only time that you might need to use this
parameter is if you need to change how the storage array behaves relative to the hosts that are connected to
it.
Before you can define the default host type, you need to determine what host types are connected to the
storage array. To return information about host types that are connected to the storage array, use the show
storageArray command with the defaultHostType parameter or the hostTypeTable parameter. This
command returns a list of the host types with which the controllers can communicate. This command does not
return a list of the hosts. These examples show the use of the show storageArray command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show storageArray defaultHostType;”
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show storageArray hostTypeTable;”
This example shows how to define a specific default host type:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set storageArray defaultHostType=11;”
The value 11 is the host type index value from the host type table that appears after entering the previous
command.

Setting the Storage Array Cache
The cache is high-speed memory that holds data that is either written to the drives or read by the host. A
controller has two memory areas that are used for intermediate storage of read data and write data. The read
cache contains data that has been read from the drives but not yet transferred to the host. The write cache
contains data from the host but not yet written to the drives.
The cache acts as a buffer so that data transfers between the host and the drive do not need to be
synchronized. In read caching, the data for a read operation from the host might already be in the cache from
a previous operation, which eliminates the need to access the drives. The data stays in the read cache until it
is flushed. For write caching, a write operation stores data from the host in cache until it can be written to the
drives.
The script command set provides two commands to define cache properties:
set storageArray
set volume
Use the set storageArray command to change the cache block size, the cache flush start value, and the
cache stop value. The command has this form:
set storageArray cacheBlockSize=cacheBlockSizeValue |
cacheFlushStart=cacheFlushStartSize |
cacheFlushStop=cacheFlushStopSize
You can enter one, two, or all three of the parameters on the command line.
The cache block size value defines the size of the data block that is used by the controller in transferring data
into or out of the cache. You can set the cache block size to either 4KB, 8KB, or 16KB. The value that you
use applies to the entire storage array and all of the volumes in the storage array. For redundant controller
configurations, this value includes all volumes owned by both controllers. Use smaller cache block sizes for
systems that require transaction processing requests or I/O streams that are typically small and random.
Use larger cache block sizes for large I/O, sequential, high#bandwidth applications. The choice of block size
affects read/write performance. Large data transfers take longer in 4-KB block sizes than 16-KB block sizes.
This example shows how to set the cacheBlockSize parameter:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set storageArray cacheBlockSize=16;”
To prevent data loss or corruption, the controller periodically writes cache data to the drives (flushes the
cache) when the amount of unwritten data in the cache reaches a predefined level, called a start percentage.
The controller also writes cache data to the drives when data has been in the cache for a predetermined
amount of time. The controller writes data to the drives until the amount of data in the cache drops to a
stop percentage level. Use the set storageArray command to set the start value and the stop value as
percentages of the filled capacity of the cache. For example, you can specify that the controller start flushing
the cache when it reaches 80-percent full and stop flushing the cache when it reaches 16-percent full. This
example shows how to set these parameters:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set storageArray cacheFlushStart=80 cacheFlushStop=16;”
Low start percentages and low stop percentages provide for maximum data protection. For both low start
percentages and low stop percentages, the chance that data requested by a read command is not in the
cache is increased. When the data is not in the cache, the cache hit percentage for writes and I/O requests
SANtricity_10.77 February 2011

decreases. Low start values and low stop values also increase the number of writes that are necessary
to maintain the cache level. Increasing the number of writes increases the system overhead and further
decreases performance.
Use the set volume command to change settings for the cache flush modifier, cache without batteries
enabled, mirror cache enabled, the read ahead multiplier, read cache enabled, and write cache enabled.
Use this command to set properties for all of the volumes or for a specific volume in a volume group. The
command has this form:
set (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN]
volume <wwID>) |
cacheFlushModifier=cacheFlushModifierValue |
cacheWithoutBatteryEnabled=(TRUE | FALSE) |
mirrorCacheEnabled=(TRUE | FALSE) |
readCacheEnabled=(TRUE | FALSE) |
writeCacheEnabled=(TRUE | FALSE) |
cacheReadPrefetch=(TRUE | FALSE)
The cacheFlushModifier parameter defines the amount of time that data stays in the cache before it is
written to the drives. The following table lists the values for the cacheFlushModifier parameter.
Values for the cacheFlushModifier Parameter
Value Meaning
Immediate Data is flushed as soon as it is placed into the cache.
250 Data is flushed after 250 ms.
500 Data is flushed after 500 ms.
750 Data is flushed after 750 ms.
1Data is flushed after 1 s.
1500 Data is flushed after 1500 ms.
2Data is flushed after 2 s.
5Data is flushed after 5 s.
10 Data is flushed after 10 s.
20 Data is flushed after 20 s.
60 Data is flushed after 60 s (1 min.).
120 Data is flushed after 120 s (2 min.).
300 Data is flushed after 300 s (5 min.).
1200 Data is flushed after 1200 s (20 min.).
3600 Data is flushed after 3600 s (1 hr.).
SANtricity_10.77 February 2011
LSI Corporation
- 1281 -
Value Meaning
Infinite Data in cache is not subject to any age or time
constraints. The data is flushed based on other criteria
managed by the controller.
This example shows how to set this parameter value for all of the volumes in the storage array:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set allvolumes cacheFlushModifier=10;”
IMPORTANT Do not set the value of the cacheFlushModifier parameter above 10 seconds.
An exception is for testing purposes. After running any tests in which you have set the values of the
cacheFlushModifier parameter above 10 seconds, return the value of the cacheFlushModifier
parameter to 10 or fewer seconds.
The cacheWithoutBatteryEnabled parameter turns on or turns off the ability of a host to perform
write caching without backup batteries in a controller. To enable write caching without batteries, set this
parameter to TRUE. To disable write caching without batteries, set this parameter to FALSE. If you set this
parameter to TRUE, write caching continues, even when the controller batteries are completely discharged,
not fully charged, or not present. If you do not have an uninterruptible power supply (UPS) and you enable
this parameter, you can lose data if power to the storage array fails. This example shows how to set this
parameter value:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Engineering\”]
cacheWithoutBatteryEnabled=FALSE;”
The mirrorCacheEnabled parameter turns on or turns off write caching with mirroring. Write caching
with mirroring permits cached data to be mirrored across redundant controllers that have the same cache
size. Data written to the cache memory of one controller also is written to the cache memory of the second
controller. If one controller fails, the second controller can complete all outstanding write operations. To use
this option, these conditions must exist:
The controller pair must be an active/active pair.
The controllers must have the same size cache.
To enable write caching with mirroring, set this parameter to TRUE. To disable write caching with mirroring,
set this parameter to FALSE. This example shows how to set this parameter:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Accounting\”] mirrorCacheEnabled=TRUE;”
The readCacheEnabled parameter turns on or turns off the ability of the host to read data from the cache.
Read caching enables read operations from the host to be stored in controller cache memory. If a host
requests data that is not in the cache, the controller reads the needed data blocks from the drives and places
them in the cache. Until the cache is flushed, all of the other requests for this data are fulfilled with cache data
rather than from a read, which increases throughput. To enable read caching, set this parameter to TRUE. To
disable read caching, set this parameter to FALSE. This example shows how to set this parameter:
c:\...\sm9\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Balance_04\”] readCacheEnabled=TRUE;”
SANtricity_10.77 February 2011
LSI Corporation
- 1282 -
The writeCacheEnabled parameter turns on or turns off the ability of the host to write data to the cache.
Write caching enables write operations from the host to be stored in cache memory. The volume data in the
cache is automatically written to the drives every 10 seconds. To enable write caching, set this parameter to
TRUE. To disable write caching, set this parameter to FALSE. This example shows how to set this parameter:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set allVolumes writeCacheEnabled=TRUE;”
The cacheReadPrefetch parameter turns on or turns off the ability of the controller to read additional data
blocks into cache. When you turn on cache read prefetch, the controller copies additional data blocks into
cache while it is reading requested data blocks from a drive into cache. This action increases the chance
that a future request for data can be fulfilled from the cache, which improves the speed with which data is
accessed. The number of additional data blocks that the controller reads into cache is determined by the
storage array configuration settings that you use. Cache read prefetch is important for applications that use
sequential I/O, such as multimedia applications.
Valid values for the cacheReadPrefetch parameter are TRUE or FALSE. If you want to turn on cache read
prefetch, set the cacheReadPrefetch parameter to TRUE. If you want to turn off cache read prefetch, set
the cacheReadPrefetch parameter to FALSE. This example shows how to set this parameter:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Engineering_1\” \”Engineering_2\”]
cacheReadPrefetch=TRUE;”
Setting the Modification Priority
Modification priority defines how much processing time is allocated for volume modification operations. Time
allocated for volume modification operations affects system performance. Increases in volume modification
priority can reduce read/write performance. The modification priority affects these operations:
Copyback
Reconstruction
Initialization
Changing the segment size
Defragmentation of a volume group
Adding free capacity to a volume group
Changing the RAID level of a volume group
The lowest priority rate favors system performance, but the modification operation takes longer. The highest
priority rate favors the modification operation, but the system performance might be degraded.
Use the set volume command to define the modification priority for a volume. The command has this form:
set (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN] volume <wwID> |
accessVolume)
modificationPriority=(highest | high | medium | low | lowest)
This example shows how to use this command to set the modification priority for volumes named
Engineering_1 and Engineering_2:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Engineering_1\” \”Engineering_2\”]
SANtricity_10.77 February 2011
LSI Corporation
- 1283 -
modificationPriority=lowest;”
The modification rate is set to lowest so that system performance is not significantly reduced by modification
operations.
Assigning Global Hot Spares
You can assign or unassign global hot spares by using the set drive command. To use this command, you
must identify the location of the drives by the tray ID and the slot ID. Then, you set the hotSpare parameter
to TRUE to enable the hot spare or FALSE to disable an existing hot spare. The command has this form:
set (drive [trayID,slotID] | drives
[trayID1,slotID1 ... trayIDn,slotIDn]) hotSpare=(TRUE | FALSE)
This example shows how to set hot spare drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set drives [1,2 1,3] hotSpare=TRUE;”
Enter the tray ID and the slot ID of each drive that you want to use. Enclose the list in square brackets,
separate the tray ID value and the slot ID value of a drive with a comma, and separate each tray ID and slot
ID pair with a space.
Saving a Configuration to a File
After you have created a new configuration or if you want to copy an existing configuration for use on other
storage arrays, you can save the configuration to a file by using the save storageArray configuration
command. Saving the configuration creates a script file that you can run on the command line. The command
has this form:
save storageArray configuration file=”filename”
[(allconfig | globalSettings=(TRUE | FALSE)) |
volumeConfigAndSettings=(TRUE | FALSE) |
hostTopology=(TRUE | FALSE) | lunMappings=(TRUE | FALSE)]
ATTENTION Possible loss of data – When information is written to a file, the script engine does not
check to determine if the file name already exists. If you choose the name of a file that already exists, the
script engine writes over the information in the file without warning.
You can choose to save the entire configuration or specific configuration features. This example shows how
to set this parameter value:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “save storagearray configuration
file=\”c:\\folder\\storagearrayconfig1.scr\”;”
In this example, the name folder is the folder in which you want to place the profile file and
storagearrayconfig1.scr is the name of the file. You can choose any folder and any file name. The
file extension for a configuration file is .scr. The storage management software uses this extension when it
creates the configuration file.

Using the Snapshot Premium Feature
The Snapshot premium feature creates a snapshot volume that you can use as a backup of your data. A
snapshot volume is a logical point-in-time image of a standard volume. Because it is not a physical copy, a
snapshot volume is created more quickly than a physical copy and requires less storage space on the drive.
Typically, you create a snapshot volume so that an application, such as a backup application, can access the
snapshot volume and read the data while the base volume stays online and user accessible. You can also
create several snapshot volumes of a base volume and write data to the snapshot volumes to perform testing
and analysis.
Snapshot volumes provide these capabilities:
Create a complete image of the data on a base volume at a particular point in time
Use only a small amount of storage space
Provide for quick, frequent, non-disruptive backups, or testing new versions of a database system without
affecting real data
Provide for snapshot volumes to be read, written, and copied
Use the same availability characteristics of the base volume (such as RAID protection and redundant path
failover)
Map the snapshot volume and make it accessible to any host on a storage area network (SAN). You
can make snapshot data available to secondary hosts for read access and write access by mapping the
snapshot to the hosts
Create up to 16 snapshots per volume and up to 1024 snapshots per storage array. The maximum
number of snapshots depends on the model of the controller. The maximum number of snapshot volumes
is one-half of the total number of volumes that are supported by the controller.
Increase the capacity of a snapshot volume
How Snapshot Works
Three components comprise a snapshot volume: the base volume, the snapshot volume, and the snapshot
repository volume. The following table lists the components and briefly describes what they do.
Components of a Snapshot Volume
Component Description
Base volume A standard volume from which the snapshot is
created
Snapshot volume A logical point-in-time image of a standard volume
Snapshot repository volume A volume that contains snapshot metadata and
copy#on-write data for a particular snapshot
volume
Based on information that you provide through the script commands, the storage management software
creates an empty snapshot repository volume and defines the mapping from a base volume to the snapshot
repository volume. The snapshot repository volume holds changed data that a host writes to the base volume.
When the snapshot repository volume is first created, it holds only the metadata about the snapshot volume
with which it is associated.
SANtricity_10.77 February 2011
LSI Corporation
- 1285 -
NOTE When you first create a snapshot repository volume, briefly stop all of the write operations to the
base volume so that a stable image of the base volume is available.
When the host writes to the base volume, the new data is also copied to the snapshot repository volume.
This action is called copy-on-write. A snapshot is constructed by combining the updated data in the snapshot
repository volume with data in the base volume that has not been altered. This action creates a complete
copy of the base volume at a specific point in time. The snapshot appears as a volume that contains the
original data at the time of creation, but the snapshot is actually an image that is the combination of the
snapshot repository volume and the original base volume. The snapshot repository volume, which houses
original data that has been changed, is the only additional drive space that is needed for the snapshot
volume. The additional drive space is typically 10 percent to 20 percent of the drive space of the base volume
and varies depending on the amount of changes to the data. The longer a snapshot volume is active, the
larger the snapshot repository volume must be. The default size of the snapshot repository volume is 20
percent of the base volume; however, you can set the size of the snapshot repository volume to other values.
You can read, write, and copy a snapshot volume. Data written by a host to the snapshot volume is handled
in the snapshot repository volume. When a write occurs to the base volume of a snapshot volume, the new
data also overwrites the appropriate snapshot repository volume data.
Snapshot Volume Commands
Command Description
create snapshotVolume This command creates a snapshot volume.
recreate snapshot This command starts a fresh copy-on-write
operation by using an existing snapshot
volume.
recreate snapshot
collection
This command restarts multiple snapshot
volumes as one batch operation by using one
or many existing snapshot volumes.
set (snapshotVolume) This command defines the properties for
a snapshot volume and lets you rename a
snapshot volume.
stop snapshot This command stops a copy-on-write
operation.
Creating a Snapshot Volume
The create snapshotVolume command provides three methods for defining the drives for your snapshot
repository volume:
Defining the drives for the snapshot repository volume by their tray IDs and their slot IDs.
Defining a volume group in which the snapshot repository volume resides. In addition, you can define the
capacity of the snapshot repository volume.
Defining the number of drives, but not specific drives, for the snapshot repository volume.
SANtricity_10.77 February 2011
LSI Corporation
- 1286 -
When you use the create snapshotVolume command to create a snapshot volume, the minimum
information that you need to provide is the standard volume that you want to use for the base volume. When
you create a snapshot volume by using minimum information, the storage management software provides
default values for the other property parameters that are required for a completely defined snapshot volume.
Creating a Snapshot Volume with User-Assigned Drives
Creating a snapshot volume by assigning the drives provides flexibility in defining your configuration by letting
you choose from the available drives in your storage array. When you choose the drives for your snapshot
volume, you automatically create a new volume group. You can specify which drives to use and the RAID
level for the new volume group. The command has this form:
create snapshotVolume baseVolume=”baseVolumeName”
[repositoryRAIDLevel=(1 | 3 | 5 | 6)
(repositoryDrives=(trayID1,slotID1 ... trayIDn,slotIDn)
userLabel=”snapshotVolumeName”
warningThresholdPercent=percentValue
repositoryPercentOfBase=percentValue
repositoryUserLabel=”repositoryName”
repositoryFullPolicy=(failBaseWrites | failSnapShot)]
[trayLossProtect=(TRUE | FALSE)]
This example shows a command in which users assign the drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create snapshotVolume baseVolume=\”Mars_Spirit_4\”
repositoryRAIDLevel=5 repositoryDrives=(1,1 1,2 1,3 1,4 1,5);”
The command in this example creates a new snapshot of the base volume Mars_Spirit_4. The snapshot
repository volume consists of five drives that form a new volume group. The new volume group has RAID
Level 5. This command also takes a snapshot of the base volume, which starts the copy-on-write operation.
This example shows how to use the command in a script file:
create snapshotVolume baseVolume=”Mars_Spirit_4” repositoryRAIDLevel=5
repositoryDrives=(1,1 1,2 1,3 1,4 1,5);
This example shows a minimal version of the command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create snapshotVolume baseVolume=\”Mars_Spirit_4\”;”
The command in this example creates a new snapshot for the base volume Mars_Spirit_4. The snapshot
repository volume is created in the same volume group as the base volume, which means that the snapshot
repository volume has the same RAID level as the base volume. This command starts the copy-on-write
operation.
This example shows how to use the command in a script file:
create snapshotVolume baseVolume=“Mars_Spirit_4”;

Creating a Snapshot Volume with Software-Assigned Drives
With this version of the create snapshotVolume command, you choose an existing volume group in
which to place the snapshot repository volume. The storage management software determines which drives
to use. You can also define how much space to assign to the snapshot repository volume. Because you are
using an existing volume group, the RAID level for the snapshot volume defaults to the RAID level of the
volume group in which you place it. You cannot define the RAID level for the snapshot volume. The command
has this form:
create snapshotVolume baseVolume=”baseVolumeName”
[repositoryVolumeGroup=volumeGroupNumber
freeCapacityArea=freeCapacityIndexNumber
userLabel=”snapshotVolumeName”
warningThresholdPercent=percentValue
repositoryPercentOfBase=percentValue
repositoryUserLabel=repositoryName
repositoryFullPolicy=(failBaseWrites | failSnapShot)]
[trayLossProtect=(TRUE | FALSE)]
This example shows a command in which the storage management software assigns the drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create snapshotVolume baseVolume=\”Mars_Spirit_4\”
repositoryVolumeGroup=2 freeCapacityArea=2;”
The command in this example creates a new snapshot repository volume in volume group 2. The base
volume is Mars_Spirit_4. The size of the snapshot repository volume is 4 GB. This command also takes a
snapshot of the base volume, starting the copy-on-write operation.
When you define the capacity of a snapshot repository volume, specify a size that is 20 percent of the size
of the base volume. In the previous example, the size of the snapshot repository volume is set to 4 GB. The
underlying assumption is that the base volume size is 20 GB (0.2 x 20 GB= 4 GB).
This example shows how to use the command in a script file:
create snapshotVolume baseVolume=”Mars_Spirit_4”
repositoryVolumeGroup=2 freeCapacityArea=2;
Creating a Snapshot Volume by Specifying a Number of Drives
With this version of the create snapshotVolume command, you must specify the number of drives
and the RAID level that you want for the snapshot repository volume. This version of the create
snapshotVolume command creates a new volume group. You must have drives in the storage array that
are not assigned to a volume group for this command to work.
create snapshotVolume baseVolume=”baseVolumeName”
[repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDriveCount=numberOfDrives
driveType=(fibre | SATA | SAS)
userLabel=”snapshotVolumeName”
warningThresholdPercent=percentValue
repositoryPercentOfBase=percentValue
repositoryUserLabel=”repositoryName”
repositoryFullPolicy=(failBaseWrites | failSnapShot)]
[trayLossProtect=(TRUE | FALSE)]

This example shows how to use a command in which users specify the number of drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create snapshotVolume baseVolume=\”Mars_Spirit_4\”
repositoryRAIDLevel=5 repositoryDriveCount=3;”
The command in this example creates a new snapshot repository volume that consists of three drives. Three
drives comprise a new volume group that has RAID Level 5. This command also takes a snapshot of the base
volume, which starts the copy-on-write operation.
This example shows how to use the command in a script file:
create snapshotVolume baseVolume= “Mars_Spirit_4”
repositoryRAIDLevel=5 repositoryDriveCount=3;
User-Defined Parameters
Use the parameters in the create snapshotVolume command to define the snapshot volume to suit the
requirements of your storage array. The following table lists the parameters and briefly describes what the
parameters do.
Snapshot Volume Parameters
Parameter Description
driveType The type of drive that you want to use for the
snapshot repository volume. The choice is fibre
(Fibre Channel), SATA, or SAS. This parameter works
only with the count-based repository method of
defining a snapshot volume.
repositoryVolumeGroup The volume group in which you want to build the
snapshot repository volume. The default value is to
build the snapshot repository volume in the same
volume group as the base volume.
freeCapacityArea The amount of storage space that you want to use for
the snapshot repository volume. Free storage space
is defined in units of bytes, KB, MB, GB, or TB.
userLabel The name that you want to give to the snapshot
volume. If you do not choose a name for the snapshot
volume, the software creates a default name by using
the base volume name. For example, with a base
volume name of Mars_Spirit_4:
When the base volume does not have a snapshot
volume, the default snapshot volume name is
Mars_Spirit_4-1.
When the base volume already has n-1 number
of snapshot volumes, the default name is
Mars_Spirit_4-n.
repositoryUserLabel The name that you want to give to the snapshot
repository volume. If you do not choose a name for
the snapshot repository volume, the software creates

Parameter Description
a default name by using the base volume name. For
example, if the base volume name is Mars_Spirit_4
and does not have an associated snapshot repository
volume, the default snapshot repository volume name
is Mars_Spirit_4-R1. If the base volume already has
n-1 number of snapshot repository volumes, the
default name is Mars_Spirit_4-Rn.
warningThresholdPercent The percentage of the capacity that you will permit
the snapshot repository volume to get before you
receive a warning that the snapshot repository volume
is nearing full. The warning value is a percentage of
the total capacity of the snapshot repository volume.
The default value is 50, which represents 50 percent
of the total capacity. (You can change this value later
by using the set snapshotVolume command.)
repositoryPercentOfBase The size of the snapshot repository volume as a
percentage of the base volume size. The default value
is 20, which represents 20 percent of the base volume
size.
repositoryFullPolicy The type of snapshot processing that you want to
continue if the snapshot repository volume is full.
You can choose to fail writes to the base volume
(failBaseWrites) or fail writes to the snapshot
volume (failSnapshot). The default value is
failSnapshot.
This example shows the create snapshotVolume command that includes user-defined parameters:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create snapshotVolume baseVolume=\”Mars_Spirit_4\”
repositoryRAIDLevel=5 repositoryDriveCount=5
driveType=fibre userLabel=\”Mars_Spirit_4_snap1\”
repositoryUserLabel=\”Mars_Spirit_4rep1\”
warningThresholdPercent=75 repositoryPercentOfBase=40
repositoryFullPolicy=failSnapshot;”
This example shows how to use the command in a script file:
create snapshotVolume baseVolume=”Mars_Spirit_4”
repositoryRAIDLevel=5 repositoryDriveCount=5 driveType=fibre
userLabel=”Mars_Spirit_4_snap1”
repositoryUserLabel=”Mars_Spirit_4_rep1”
warningThresholdPercent=75 repositoryPercentOfBase=40
repositoryFullPolicy=failSnapshot;

Snapshot Volume Names and Snapshot Repository Volume Names
The snapshot volume names and the snapshot repository volume names can be any combination of
alphanumeric characters, hyphens, and underscores. The maximum length of the volume names is 30
characters. You must enclose the volume name in double quotation marks. The character string cannot
contain a new line. Make sure that you use unique names; if you do not use unique names, the controller
firmware returns an error.
One technique for naming the snapshot volume and the snapshot repository volume is to add a hyphenated
suffix to the original base volume name. The suffix distinguishes between the snapshot volume and the
snapshot repository volume. For example, if you have a base volume with a name of Engineering Data, the
snapshot volume can have a name of Engineering Data-S1, and the snapshot repository volume can have a
name of Engineering Data-R1.
If you do not choose a unique name for either the snapshot volume or the snapshot repository volume, the
controllers create a default name by using the base volume name. These examples are snapshot volume
names that the controllers might create:
If the base volume name is aaa and does not have a snapshot volume, the default snapshot volume
name is aaa1.
If the base volume already has n-1 number of snapshot volumes, the default name is aaa-n.
If the base volume name is aaa and does not have a snapshot repository volume, the default snapshot
repository volume name is aaa-R1.
If the base volume already has n-1 number of snapshot repository volumes, the default name is aaa-Rn.
In the examples from the previous section, the user-defined snapshot volume name was
Mars_Spirit_4_snap1, and the user-defined snapshot repository volume name was Mars_Spirit_4_rep1. The
default name that was provided by the controller for the snapshot volume was Mars_Spirit_4-1. The default
name that was provided by the controller for the snapshot repository volume was Mars_Spirit_4-R1.
Changing Snapshot Volume Settings
Use the set (snapshot) volume command to change these property settings for a snapshot volume:
The snapshot volume name
The warning threshold percent
The snapshot repository full policy
This example shows how to change a snapshot volume name.
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volume [\”Mars_Spirit_4-1\”]
userLabel=\”Mars_Odyssey_3-2\”;”
This example shows how to use the command in a script file:
set volume [“Mars_Spirit_4-1”] userLabel=”Mars_Odyssey_3-2”;
When you change the warning threshold percent and the snapshot repository full policy, you can apply the
changes to one or several snapshot volumes with this command. This example shows how to use the set
(snapshot) volume command to change these properties on more than one snapshot volume:

-c “set volume
[\”Mars_Spirit_4-1\” \”Mars_Spirit_4-2\” \”Mars_Spirit_4-3\”
warningThresholdPercent=50
repositoryFullPolicy=failBaseWrites;”
This example shows how to use the command in a script file:
set volume [“Mars_Spirit_4-1” “Mars_Spirit_4-2”
“Mars_Spirit_4-3”] warningThresholdPercent=50
repositoryFullPolicy=failBaseWrites;
Stopping, Restarting, and Deleting a Snapshot Volume
When you create a snapshot volume, copy-on-write starts running immediately. As long as a snapshot
volume is enabled, storage array performance is impacted by the copy-on-write operations to the associated
snapshot repository volume.
If you no longer want copy-on-write operations to run, you can use the stop snapshot volume command
to stop the copy-on-write operations. When you stop a snapshot volume, the snapshot volume and the
snapshot repository volume are still defined for the base volume. Only copy-on-write has stopped. This
example shows how to stop a snapshot volume:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “stop snapshot volumes
[\”Mars_Spirit_4-2\” \”Mars_Spirit_4-3\”];”
This example shows how to use the command in a script file:
stop snapshot volumes
[“Mars_Spirit_4-2” “Mars_Spirit_4-3”];
When you stop the copy-on-write operations for a specific snapshot volume, only that snapshot volume is
disabled. All of the other snapshot volumes stay in operation.
When you want to restart a copy-on-write operation, use the recreate snapshot volume command or
the recreate snapshot collection command. The recreate snapshot volume command starts a
fresh copy-on-write operation by using an existing snapshot volume.
NOTE The snapshot volume must be in either an Optimal state or a Disabled state.
When you restart a snapshot volume, these actions occur:
All copy-on-write data previously on the snapshot repository volume is overwritten.
Snapshot volume parameters and snapshot repository volume parameters stay the same as the
previously disabled snapshot volume and the previously disabled snapshot repository volume. You
can also change the userLabel parameter, the warningThresholdPercent parameter, and the
repositoryFullPolicy parameter when you restart the snapshot volume.
The original names for the snapshot repository volume are retained.
This example shows how to restart a snapshot volume:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “recreate snapshot volumes
[\”Mars_Spirit_4-2\” \”Mars_Spirit_4-3\”];”

If you do not intend to use a snapshot volume again, you can delete the snapshot volume by using the
delete volume command. When you delete a snapshot volume, the associated snapshot repository
volume also is deleted.

Using the Remote Volume Mirroring Premium Feature
The Remote Volume Mirroring premium feature provides for online, real-time replication of data between
storage arrays over a remote distance. In the event of a disaster or a catastrophic failure on one storage
array, you can promote the second storage array to take over responsibility for computing services. Remote
Volume Mirroring is designed for extended storage environments in which the storage arrays that are used
for Remote Volume Mirroring are maintained at separate sites. Volumes on one storage array are mirrored to
volumes on another storage array across a fabric SAN. Data transfers can be synchronous or asynchronous.
You choose the method when you set up the remote-mirror pair. The data transfers occur at Fibre Channel
speeds to maintain data on the different storage arrays. Because Remote Volume Mirroring is storage based,
it does not require any server overhead or application overhead.
You can use Remote Volume Mirroring for these functions:
Disaster recovery – Remote Volume Mirroring lets you replicate data from one site to another site, which
provides an exact mirror duplicate at the remote (secondary) site. If the primary site fails, you can use
mirrored data at the remote site for failover and recovery. You can then shift storage operations to the
remote site for continued operation of all of the services that are usually provided by the primary site.
Data vaulting and data availability – Remote Volume Mirroring lets you send data off site where it can
be protected. You can then use the off#site copy for testing or to act as a source for a full backup to avoid
interrupting operations at the primary site.
Two-way data protection – Remote Volume Mirroring provides the ability to have two storage arrays
back up each other by mirroring critical volumes on each storage array to volumes on the other storage
array. This action lets each storage array recover data from the other storage array in the event of any
service interruptions.
How Remote Volume Mirroring Works
When you create a remote-mirror pair, the remote-mirror pair consists of a primary volume on a local storage
array and a secondary volume on a storage array at another site. A standard volume might only be included
in one mirrored volume pair.

The primary volume is the volume that accepts host I/O activity and stores application data. When the mirror
relationship is first created, data from the primary volume is copied in its entirety to the secondary volume.
This process is known as a full synchronization and is directed by the controller owner of the primary volume.
During a full synchronization, the primary volume remains fully accessible for all normal I/O operations.
SANtricity_10.77 February 2011
LSI Corporation
- 1294 -
The controller owner of the primary volume initiates remote writes to the secondary volume to keep the data
on the two volumes synchronized.
The secondary volume maintains a mirror (or copy) of the data on its associated primary volume. The
controller owner of the secondary volume receives remote writes from the controller owner of the primary
volume but will not accept host write requests. Hosts are able to read from the secondary volume, which
appears as read-only.
In the event of a disaster or a catastrophic failure at the primary site, you can perform a role reversal to
promote the secondary volume to a primary role. Hosts then are able to read from and write to the newly
promoted volume, and business operations can continue.
Mirror Repository Volumes
A mirror repository volume is a special volume in the storage array that is created as a resource for the
controller owner of the primary volume in a remote-mirror pair. The controller stores mirroring information on
this volume, including information about remote writes that are not yet complete. The controller can use this
information to recover from controller resets and the accidental powering down of the storage arrays.
When you activate the Remote Volume Mirroring premium feature on the storage array, you create two mirror
repository volumes, one for each controller in the storage array. An individual mirror repository volume is not
needed for each remote mirror.
When you create the mirror repository volumes, you specify the location of the volumes. You can either use
existing free capacity, or you can create a volume group for the volumes from unconfigured capacity and then
specify the RAID level.
Because of the critical nature of the data being stored, do not use RAID Level 0 as the RAID level of mirror
repository volumes. The required size of each volume is 128 MB, or 256 MB total for both mirror repository
volumes of a dual-controller storage array. In previous versions of the Remote Volume Mirroring premium
feature, the mirror repository volumes required less disk storage space and needed to be upgraded to use the
maximum amount of mirror relationships.
Mirror Relationships
Before you create a mirror relationship, you must enable the Remote Volume Mirroring premium feature on
both the primary storage array and the secondary storage array. You must also create a secondary volume
on the secondary site if one does not already exist. The secondary volume must be a standard volume of
equal or greater capacity than the associated primary volume.
When secondary volumes are available, you can establish a mirror relationship in the storage management
software by identifying the primary volume and the storage array that contains the secondary volume.
When you first create the mirror relationship, a full synchronization automatically occurs, with data from the
primary volume copied in its entirety to the secondary volume.
Data Replication
The controllers manage data replication between the primary volume and the secondary volume. This
process is transparent to host machines and applications. This section describes how data is replicated
between the storage arrays that are participating in Remote Volume Mirroring. This section also describes
the actions taken by the controller owner of the primary volume if a link interruption occurs between storage
arrays.
SANtricity_10.77 February 2011

Write Modes
When the controller owner of the primary volume receives a write request from a host, the controller first logs
information about the write to a mirror repository volume, and then writes the data to the primary volume. The
controller then initiates a remote write operation to copy the affected data blocks to the secondary volume at
the secondary storage array.
The Remote Volume Mirroring premium feature provides two write mode options that affect when the I/O
completion indication is sent back to the host: Synchronous and Asynchronous.
Synchronous Write Mode
Synchronous write mode provides the highest level security for full data recovery from the secondary
storage array in the event of a disaster. Synchronous write mode does reduce host I/O performance. When
this write mode is selected, host write requests are written to the primary volume and then copied to the
secondary volume. After the host write request has been written to the primary volume and the data has been
successfully copied to the secondary volume, the controller removes the log record on the mirror repository
volume. The controller then sends an I/O completion indication back to the host system. Synchronous write
mode is selected as the default value and is the recommended write mode.
Asynchronous Write Mode
Asynchronous write mode offers faster host I/O performance but does not guarantee that a copy operation
has successfully completed before processing the next write request. When you use Asynchronous write
mode, host write requests are written to the primary volume. The controller then sends an “I/O complete”
indication back to the host system, without acknowledging that the data has been successfully copied to the
secondary (remote) storage array.
When using Asynchronous write mode, write requests are not guaranteed to be completed in the same order
on the secondary volume as they are on the primary volume. If the order of write requests is not retained,
data on the secondary volume might become inconsistent with the data on the primary volume. This event
could jeopardize any attempt to recover data if a disaster occurs on the primary storage array.
Write Consistency Mode
When multiple mirror relationships exist on a single storage array and have been configured to use
Asynchronous write mode and to preserve consistent write order, they are considered to be an
interdependent group that is in the Write consistency mode. The data on the secondary, remote storage array
cannot be considered fully synchronized until all of the remote mirrors that are in the Write consistency mode
are synchronized.
If one mirror relationship in the group becomes unsynchronized, all of the mirror relationships in the group
become unsynchronized. Any write activity to the remote, secondary storage arrays is prevented to protect
the consistency of the remote data set.
Link Interruptions or Secondary Volume Errors
When processing write requests, the primary controller might be able to write to the primary volume, but a link
interruption might prevent communication with the remote (secondary) controller.
In this case, the remote write operation cannot be completed to the secondary volume, and the primary
volume and the secondary volume are no longer correctly mirrored. The primary controller transitions the
mirrored pair into an Unsynchronized state and sends an I/O completion to the primary host. The primary host
can continue to write to the primary volume, but remote writes do not take place.
SANtricity_10.77 February 2011
LSI Corporation
- 1296 -
When communication is restored between the controller owner of the primary volume and the controller owner
of the secondary volume, a resynchronization takes place. This resynchronization happens automatically, or it
must be started manually, depending on which write mode you chose when setting up the mirror relationship.
During the resynchronization, only the blocks of data that have changed on the primary volume during the
link interruption are copied to the secondary volume. After the resynchronization starts, the mirrored pair
transitions from an Unsynchronized status to a Synchronization in Progress status.
The primary controller also marks the mirrored pair as unsynchronized when a volume error on the secondary
side prevents the remote write from completing. For example, an offline secondary volume or a failed
secondary volume can cause the remote mirror to become unsynchronized. When the volume error is
corrected (the secondary volume is placed online or recovered to an Optimal status), then synchronization is
required. The mirrored pair then transitions to a Synchronization in Progress status.
Resynchronization
Data replication between the primary volume and the secondary volume in a mirror relationship is managed
by the controllers and is transparent to host machines and applications. When the controller owner of the
primary volume receives a write request from a host, the controller first logs information about the write to
a mirror repository volume. The controller then writes the data to the primary volume. The controller then
initiates a write operation to copy the affected data to the secondary volume on the remote storage array.
If a link interruption or a volume error prevents communication with the secondary storage array, the controller
owner of the primary volume transitions the mirrored pair into an Unsynchronized status. The controller owner
then sends an I/O completion to the host sending the write request. The host can continue to issue write
requests to the primary volume, but remote writes to the secondary volume do not take place.
When connectivity is restored between the controller owner of the primary volume and the controller owner
of the secondary volume, the volumes must be resynchronized by copying the blocks of data that changed
during the interruption to the secondary volume. Only the blocks of data that have changed on the primary
volume during the link interruption are copied to the secondary volume.
ATTENTION Possible loss of data access – Any communication disruptions between the primary
storage array and the secondary storage array while resynchronization is underway could result in a mix of
new data and old data on the secondary volume. This condition would render the data unusable in a disaster
recovery situation.
Creating a Remote-Mirror Pair
Before you create any mirror relationships, volumes must exist at both the primary site and the secondary
site. The volume that resides on the local storage array is the primary volume. Similarly, the volume that
resides on the remote storage array is the secondary volume. If neither the primary volume nor the secondary
volume exist, you must create these volumes. Keep these guidelines in mind when you create the secondary
volume:
The secondary volume must be of equal or greater size than the primary volume.
The RAID level of the secondary volume does not have to be the same as the primary volume.
Use these steps to create the volume.
1. Enable the Remote Volume Mirroring premium feature.
2. Activate the Remote Volume Mirroring premium feature.
3. Determine candidates for a remote-mirror pair.
4. Create the remote-mirror relationship.

Performance Considerations
Keep these performance issues in mind when you create mirror relationships:
The controller owner of a primary volume performs a full synchronization in the background while
processing local I/O writes to the primary volume and associated remote writes to the secondary
volume. Because the full synchronization diverts controller processing resources from I/O writes, full
synchronization can have a performance impact to the host application.
To reduce the performance impact, you can set the synchronization priority level to determine how
the controller owner will prioritize the full synchronization relative to other I/O activity. To set the
synchronization priority level, consider these guidelines:
A full synchronization at the lowest synchronization priority level takes approximately eight times as
long as a full synchronization at the highest synchronization priority level.
A full synchronization at the low synchronization priority level takes approximately six times as long
as a full synchronization at the highest synchronization priority level.
A full synchronization at the medium synchronization priority level takes approximately three-and-a-
half times as long as a full synchronization at the highest synchronization priority level.
A full synchronization at the high synchronization priority level takes approximately twice as long as a
full synchronization at the highest synchronization priority level.
When the mirrored volume pair is in a Synchronization in Progress state, all host write data is copied to
the remote system. Both controller I/O bandwidth and I/O latency can affect host write performance. Host
read performance is not affected by the mirroring relationship.
The time that it takes for data to be copied from the primary volume to the secondary volume might
impact overall performance. This impact is primarily caused by the delay and system resource required
for copying data to the remote mirror. Some delay might also occur because of the limit to the number of
simultaneous writes.
Enabling the Remote Volume Mirroring Premium Feature
The first step in creating a remote mirror is to make sure that the Remote Volume Mirroring premium feature
is enabled on both storage arrays. Because Remote Volume Mirroring is a premium feature, you need a
feature key file to enable the premium feature. The command for enabling the feature key file is as follows:
enable storageArray feature file=”filename”
In this command, the file parameter is the complete file path and file name of a valid feature key file.
Enclose the file path and the file name in double quotation marks (“ ”). Valid file names for feature key files
end with a .key extension.
Activating the Remote Volume Mirroring Premium Feature
Activating the Remote Volume Mirroring premium feature prepares the storage arrays to create and configure
mirror relationships. After you activate the premium feature, the secondary ports for each controller are
reserved and dedicated to remote mirror use. In addition, a mirror repository volume is automatically created
for each controller in the storage array. As part of the activation process, you can decide where the mirror
repository volumes will reside, free capacity on an existing volume group or in a newly created volume group,
and the RAID level for the mirror repository volumes.
The free capacity that you select for the mirror repository volume must have a total of 256 MB of capacity
available. Two mirror repository volumes are created on this capacity, one for each controller. If you enter a
value for the repository storage space that is too small for the mirror repository volumes, the firmware returns
SANtricity_10.77 February 2011
LSI Corporation
- 1298 -
an error message that gives the amount of space needed for the mirror repository volumes. The command
does not try to activate the Remote Volume Mirroring premium feature. You can re-enter the command using
the value from the error message for the repository storage space value.
The RAID level that you choose for the mirror repository volume has these constraints:
RAID Level 0 – You cannot use RAID Level 0.
RAID Level 1 – The number of drives must be an even number. If you select an odd number of drives,
the controller firmware returns an error.
RAID Level 3 or RAID Level 5 – You must have a minimum of three drives in the volume group.
RAID Level 6 – You must have a minimum of five drives in the volume group.
To activate the Remote Volume Mirroring premium feature, use this command:
activate storageArray feature=remoteMirror
The activate storageArray feature=remoteMirror command provides three methods for defining
the drives for your mirror repository volume:
You define each drive for the mirror repository volume by its tray ID and its slot ID.
You define a volume group in which the mirror repository volume resides. You can optionally define the
capacity of the mirror repository volume.
You define the number of drives, but not specific drives, for the mirror repository volume.
Activating the Remote Volume Mirroring Premium Feature with User-Assigned
Drives
Activating the Remote Volume Mirroring premium feature by assigning the drives provides flexibility in
defining your configuration by letting you choose from the available drives in your storage array. Choosing the
drives for your remote mirror automatically creates a new volume group. You can specify which drives to use
and the RAID level for the new volume group.
The command takes this form:
activate storageArray feature=remoteMirror
repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDrives=(trayID1,slotID1 ... trayIDn,slotIDn)
trayLossProtect=(TRUE | FALSE)
This example shows a command in which you assign the drives:
c:\...\smX\client>smcli 123.45.67.89
-c “activate storageArray feature=remoteMirror
repositoryRAIDLevel=5
repositoryDrives=(1,1 1,2 1,3 1,4 1,5);”
The command in this example creates a new mirror repository volume consisting of five drives that form a
new volume group. The new volume group has RAID Level 5.
This example shows how to use the command in a script file:
activate storageArray feature=remoteMirror
repositoryRAIDLevel=5
repositoryDrives=(1,1 1,2 1,3 1,4 1,5);

Activating the Remote Volume Mirroring Premium Feature with Software-Assigned
Drives
With this version of the activate storageArray feature=remoteMirror command, you choose an
existing volume group in which to place the mirror repository volume. The storage management software
then determines which drives to use. You can also define how much space to assign to the mirror repository
volume. Because you are using an existing volume group, the RAID level for the mirror repository volume
defaults to the RAID level of the volume group in which you place it. You cannot define the RAID level for the
mirror repository volume.
The command takes this form:
activate storageArray feature=remoteMirror
repositoryVolumeGroup=volumeGroupNumber
[freeCapacityArea=freeCapacityIndexNumber]
This example shows a command in which the software assigns the drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “activate storageArray feature=remoteMirror
repositoryVolumeGroup=2 freeCapacityArea=2;”
The command in this example creates a new mirror repository volume in volume group 2 using the second
free capacity area.
This example shows how to use the command in a script file:
activate storageArray feature=remoteMirror
repositoryVolumeGroup=2 freeCapacityArea=2;
Activating the Remote Volume Mirroring Premium Feature by Specifying a Number of
Drives
With this version of the activate storageArray feature=remoteMirror command, you must specify
the number of drives and the RAID level that you want for the mirror repository volume. This version of the
command creates a new volume group. For this command to work, you must have drives in the storage array
that are not assigned to a volume group.
activate storageArray feature=remoteMirror
repositoryRAIDLevel=(1 | 3 | 5 | 6)
repositoryDriveCount=numberOfDrives
[driveType=(fibre | SATA | SAS)]
[trayLossProtect=(TRUE | FALSE)]
This example shows a command in which you specify the number of drives:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “activate storageArray feature=remoteMirror
repositoryRAIDLevel=5 repositoryDriveCount=5
driveType=fibre;”
The command in this example creates a new mirror repository volume by using five software#selected drives
for the mirror repository volume. The mirror repository volume has RAID Level 5. The type of drive for the
mirror repository volume is Fibre Channel.

Determining Candidates for a Remote-Mirror Pair
All of the volumes and drives on the remote storage array might not be available for use as secondary
volumes. To determine which volumes on a remote storage array that you can use as candidates for
secondary volumes, use the show remoteMirror candidates command. This command returns a list of
the volumes that you can use when creating a remote mirror.
The command takes this form:
c:\...\sm9\client>smcli 123.45.67.89 -c “show
remoteMirror candidates primary=\“volumeName\”
remoteStorageArrayName=\“storageArrayName\”;”
where volumeName is the name of the volume that you want to use for the primary volume, and
storageArrayName is the remote storage array that contains possible candidates for the secondary
volume. Enclose both the volume name and the storage array name in double quotation marks (“ ”).
Creating a Remote-Mirror Pair
When you create a new remote mirror, you must define which volumes that you want to use for the primary
(local) volume and the secondary (remote) volume. You define the primary volume by the name of the
volume. You define the secondary volume by name with either the name or the World Wide Identifier (WWID)
of the storage array on which the secondary volume resides. The primary volume name, the secondary
volume name, and the remote storage array name (or WWID) are the minimum information that you need to
provide. Using this command, you can also define synchronization priority, write order, and write mode.
The command takes this form:
create remoteMirror primary=“primaryVolumeName”
secondary=“secondaryVolumeName”
(remoteStorageArrayName=“storageArrayName” |
remoteStorageArrayWwn=“wwID”) remotePassword=password
syncPriority=(highest | high | medium | low | lowest)
writeOrder=(preserved | notPreserved)
writeMode=(synchronous | asynchronous)
NOTE You can use the optional parameters as needed to help define your configuration.
This example shows the create remoteMirror command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create remoteMirror primary=\”Jan_04_Account\”
secondary=\”Jan_04_Account_B\” remoteStorageArrayName=\”Tabor\”
remotePassword=\”jdw2ga05\” syncPriority=highest
writeMode=synchronous;”

The command in this example creates a remote mirror in which the primary volume is named
Jan_04_Account on the local storage array. The secondary volume is named Jan_04_Account_B on the
remote storage array that is named Tabor. The names used in this example are similar, but that is not a
requirement for the volume names in a remote-mirror pair. In this example, the remote storage array has a
password that you must enter when making any change to the storage array configuration. Creating a remote-
mirror pair is a significant change to a storage array configuration. Setting the write mode to synchronous
and the synchronization priority to highest means that host write requests are written to the primary volume
and then immediately copied to the secondary volume. These actions help to make sure that the data on
the secondary volume is as accurate a copy of the data on the primary volume as possible. The highest
synchronization priority does, however, use more system resources, which can reduce system performance.
This example shows how to use the command in a script file:
create remoteMirror primary=”Jan_04_Account”
secondary=”Jan_04_Account_B” remoteStorageArrayName=”Tabor”
remotePassword=”jdw2ga05” syncPriority=highest
writeMode=synchronous;
After you have created a remote mirror, you can see the progress of data synchronization
between the primary volume and the secondary volume by running the show remoteMirror
synchronizationProgress command. This command shows the progress as a percentage of data
synchronization that has completed.
Changing Remote Volume Mirroring Settings
The set remoteMirror command lets you change the property settings for a remote-mirror pair. Use this
command to change these property settings:
The volume role (either primary or secondary)
The synchronization priority
The write order
The write mode
You can apply the changes to one or several remote-mirror pairs by using this command. Use the primary
volume name to identify the remote-mirror pairs for which you are changing the properties.
This example shows how to use the set remoteMirror command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set remoteMirror localVolume [Jan_04_Account]
syncPriority=medium
writeOrder=notpreserved
writeMode=asynchronous;”
This example shows how to use the command in a script file:
set remoteMirror localVolume [Jan_04_Account]
syncPriority=medium
writeOrder=notpreserved
writeMode=asynchronous;

Suspending and Resuming a Mirror Relationship
Use the suspend remoteMirror command to stop data transfer between a primary volume and a
secondary volume in a mirror relationship without disabling the mirror relationship. Suspending a mirror
relationship lets you control when the data on the primary volume and data on the secondary volume
are synchronized. Suspending a mirror relationship helps to reduce any performance impact to the host
application that might occur while any changed data on the primary volume is copied to the secondary
volume. Suspending a mirror relationship is particularly useful when you want to run a backup of the data on
the secondary volume.
When a mirror relationship is in a suspended state, the primary volume does not make any attempt to contact
the secondary volume. Any writes to the primary volume are persistently logged in the mirror repository
volumes. After the mirror relationship resumes, any data that is written to the primary volume is automatically
written to the secondary volume. Only the modified data blocks on the primary volume are written to the
secondary volume. Full synchronization is not required.
IMPORTANT If you suspend a remote mirror that is set up in the Write consistency mode, you suspend
all remote-mirror pairs within the group. You can then resume mirror operations for any of the individual
remote-mirror pairs that are in the group.
This example shows the suspend remoteMirror command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “suspend remoteMirror primary Jan_04_Account
writeConsistency=false;”
The writeConsistency parameter defines whether the volumes identified in this command are in a write-
consistency group or are separate. For the volumes in a write#consistency group, set this parameter to TRUE.
For the volumes that are not in a write-consistency group, set this parameter to FALSE.
This example shows how to use the command in a script file:
suspend remoteMirror volume Jan_04_Account writeConsistency=false;
The mirror relationship remains suspended until you use the resume remoteMirror command to restart
synchronization activities. This command restarts data transfers between a primary volume and a secondary
volume in a mirror relationship after the mirror has been suspended or unsynchronized.
This example shows the resume remoteMirror command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “resume remoteMirror volume Jan_04_Account
writeConsistency=false;”
The writeConsistency parameter in this command operates the same as in the previous command.
This example shows how to use the command in a script file:
resume remoteMirror volume Jan_04_Account
writeConsistency=false;

Removing a Mirror Relationship
Use the remove remoteMirror command to remove the link between a primary volume and a secondary
volume. (Removing a mirror relationship is similar to deleting a mirror relationship.) Removing the link
between a primary volume and a secondary volume does not affect any of the existing data on either volume.
The link between the volumes is removed, but the primary volume still continues normal I/O operations. Later,
you can establish the mirror relationship between the two volumes and resume normal mirror operations. You
can remove the mirror relationship for one or several remote-mirror pairs with this command.
This example shows the remove remoteMirror command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “remove remoteMirror localVolume [Jan_04_Account];”
When you run this command, use the name of the primary volume of the remote#mirror pair.
This example shows how to use the command in a script file:
remove remoteMirror localVolume [Jan_04_Account];
To re-establish the link between a primary volume and a secondary volume, use the create
remoteMirror command.
Deleting a Primary Volume or a Secondary Volume
Use the delete volume command to remove a primary volume or a secondary volume from a storage
array. Deleting a volume in a mirror relationship removes the mirror relationship and completely deletes the
volume from the storage array. You cannot redefine the mirror relationship until you create a new volume or
choose an alternate volume to replace the deleted volume.
ATTENTION Possible loss of data access – Deleting a primary volume or a secondary volume
permanently removes the data from the storage array.
Disabling the Remote Volume Mirroring Premium Feature
You disable the Remote Volume Mirroring premium feature to prevent the new mirror relationship from
being created. When you disable the Remote Volume Mirroring premium feature, the premium feature is in
a Disabled/Active state. In this state, you can maintain and manage previously existing mirror relationships;
however, you cannot create new relationships. To disable the Remote Volume Mirroring premium feature, use
this command:
disable storageArray feature=remoteMirror
Deactivating the Remote Volume Mirroring Premium Feature
If you no longer require the Remote Volume Mirroring premium feature and you have removed all of the mirror
relationships, you can deactivate the premium feature. Deactivating the premium feature re#establishes
the normal use of dedicated ports on both storage arrays and deletes both mirror repository volumes. To
deactivate the Remote Volume Mirroring premium feature, use this command:
deactivate storageArray feature=remoteMirror

Interaction with Other Premium Features
You can run the Remote Volume Mirroring premium feature while running these premium features:
Storage Partitioning
Snapshot
Volume Copy
When you run the Remote Volume Mirroring premium feature with other premium features, you must consider
the requirements of the other premium features to help make sure that you set up a stable storage array
configuration.
In addition to running with the premium features, you can also run the Remote Volume Mirroring premium
feature while running Dynamic Volume Expansion (DVE).
Storage Partitioning
Storage Partitioning is a premium feature that lets hosts share access to volumes in a storage array. You
create a storage partition when you define any of these logical components in a storage array:
A host
A host group
A volume-to-LUN mapping
The volume-to-LUN mapping lets you define which host group or host has access to a particular volume in the
storage array.
When you create storage partitions, define the storage partitions after you have created the primary volume
and the secondary volume in a Remote Volume Mirroring configuration. The storage partition definitions for
the primary storage array and the secondary storage array are independent of each other. If these definitions
are put in place while the volume is in a secondary role, the administrative effort associated with the site
recovery is reduced if it becomes necessary to promote the volume to a primary role.
Volume Copy
The Volume Copy premium feature copies data from one volume (the source volume) to another volume (the
target volume) within a single storage array. You can use this premium feature to perform these functions:
Copy data from volume groups that use smaller-capacity drives to volume groups that use larger-capacity
drives
Back up data
Restore snapshot volume data to the base volume.
You can use a primary volume in a remote mirror as a source volume or a target volume in a volume copy.
You cannot use a secondary volume as a source volume or a target volume.
NOTE If you start a role reversal during a copy-in-progress, the copy fails and cannot be restarted.
SANtricity_10.77 February 2011
LSI Corporation

Dynamic Volume Expansion
A Dynamic Volume Expansion (DVE) is a modification operation that increases the capacity of a standard
volume or a snapshot repository volume. The increase in capacity is achieved by using the free capacity that
is available in the volume group of the standard volume or the snapshot repository volume.
This modification operation is considered to be “dynamic” because you can continually access data on
volume groups, volumes, and drives throughout the entire operation.
A DVE operation can be performed on a primary volume or a secondary volume of a mirror relationship.
NOTE Although the storage management software indicates that the volume has increased capacity, its
usable capacity is the size of the smaller of the primary volume or the secondary volume.
You cannot perform a DVE operation on a mirror repository volume.

Using the Volume Copy Premium Feature
The Volume Copy premium feature lets you copy data from one volume (the source) to another volume (the
target) in a single storage array. You can use this premium feature to perform these tasks:
Back up data
Copy data from volume groups that use smaller-capacity drives to volume groups using greater-capacity
drives
Restore snapshot volume data to the associated base volume
How Volume Copy Works
When you create a volume copy, you create a copy pair that consists of a source volume and a target
volume. Both the source volume and the target volume are located on the same storage array. During a
volume copy, the controllers manage copying the data from the source volume to the target volume. The
volume copy is transparent to the host machines and applications, except that users cannot write to the
source volume during a volume copy.
While a volume copy is In Progress, the same controller must own both the source volume and the target
volume. If one controller does not own both the source volume and the target volume before creating the
volume copy, ownership of the target volume is automatically transferred to the controller that owns the
source volume. When the volume copy is finished or stopped, ownership of the target volume is restored to its
preferred controller. If ownership of the source volume changes while a volume copy is running, ownership of
the target volume also changes.
Source Volume
The source volume is the volume that accepts host I/O and stores data. When you start a volume copy, data
from the source volume is copied in its entirety to the target volume. While a volume copy has a status of In
Progress, Pending, or Failed, the source volume is available only for read activity.
After the volume copy completes, the source volume becomes available to host applications for write
requests. The target volume automatically becomes read only to hosts, and write requests to the target
volume are rejected.
The following are valid source volumes:
A standard volume
A snapshot volume
The base volume of a snapshot volume
A primary volume that is participating in a remote-mirror pair
The following are not valid source volumes:
A secondary volume that is participating in a remote-mirror pair
A snapshot repository volume
A mirror repository volume
A failed volume
A missing volume
A volume currently in a modification operation
SANtricity_10.77 February 2011

A volume that is holding a Small Computer System Interface-2 (SCSI-2) reservation or a persistent
reservation
A volume that is a source volume or a target volume in another volume copy that has a status of In
Progress, Pending, or Failed
Target Volume
A target volume contains a copy of the data from the source volume. When a volume copy is started, data
from the source volume is copied in its entirety to the target volume.
ATTENTION Possible loss of data access – A volume copy overwrites data on the target volume.
Before you start a new operation, make sure that you no longer need the old data, or you have backed up the
old data on the target volume.
While the volume copy has a status of In Progress, Pending, or Failed, the controllers reject read and write
requests to the target volume. After the volume copy operation is finished, the target volume automatically
becomes read only to the hosts, and write requests to the target volume are rejected. You can change the
Read-Only attribute after the volume copy has completed or has been stopped. (For more information about
the Read-Only attribute, see “Viewing Volume Copy Properties.”
The following volumes are valid target volumes:
A standard volume
The base volume of a disabled snapshot volume or failed snapshot volume
A primary volume that is participating in a remote-mirror pair
The following volumes are not valid target volumes:
The base volume of an active snapshot volume
A snapshot volume
A mirror repository volume
A snapshot repository volume
A secondary volume in a remote-mirror pair
A failed volume
A missing volume
A volume with a status of Degraded
A volume that is currently in a modification operation
A volume that is holding a SCSI-2 reservation or a persistent reservation
A volume that is a source volume or a target volume in another volume copy that has a status of In
Progress, Pending, or Failed
Volume Copy and Persistent Reservations
You cannot use volumes that hold persistent reservations for either a source volume or a target volume.
Persistent reservations are configured and managed through the server cluster software and prevent other
hosts from accessing the reserved volume. Unlike other types of reservations, a persistent reservation
reserves host access to the volume across multiple HBA host ports, which provides various levels of access
control.
SANtricity_10.77 February 2011

To determine which volumes have reservations, run the show (volume) reservations command. To
remove a reservation, run the clear (volume) reservations command.
Storage Array Performance
During a volume copy operation, the resources of the storage array might be diverted from processing I/O
activity to completing a volume copy, which might affect the overall performance of the storage array.
These factors contribute to the performance of the storage array:
The I/O activity
The volume RAID level
The volume configuration (number of drives in the volume groups and cache parameters)
The volume type (snapshot volumes might take more time to copy than standard volumes)
When you create a new volume copy, you define the copy priority to determine how much controller
processing time is allocated for a volume copy compared with I/O activity.
Copy priority has five relative settings ranging from highest to lowest. The highest priority rate supports the
volume copy, but I/O activity might be affected. The lowest priority rate supports I/O activity, but the volume
copy takes longer. You define the copy priority when you create the volume copy pair. You can redefine the
copy priority later by using the set volumeCopy command. You can also redefine the volume copy priority
when you recopy a volume.
Restrictions
These restrictions apply to the source volume, the target volume, and the storage array:
While a volume copy operation has a status of In Progress, Pending, or Failed, the source volume is
available for read activity only. After the volume copy finishes, read activity from and write activity to the
source volume is permitted.
A volume can be selected as a target volume for only one volume copy at a time.
The maximum allowable number of volume copies per storage array depends upon the storage array
configuration.
A volume that is reserved by the host cannot be selected as a source volume or as a target volume.
A volume with a status of Failed cannot be used as a source volume or as a target volume.
A volume with a status of Degraded cannot be used as a target volume.
You cannot select a volume that is participating in a modification operation as a source volume or as
a target volume. Modification operations include Dynamic Capacity Expansion (DCE), Dynamic RAID
Level Migration (DRM), Dynamic Segment Sizing (DSS), Dynamic Volume Expansion (DVE), and
defragmenting a volume group.
Volume Copy Commands
The following table lists the Volume Copy commands and briefly describes what the commands do.
SANtricity_10.77 February 2011

Volume Copy Commands
Command Description
create volumeCopy Creates a volume copy and starts the volume
copy operation.
disable storageArray
featurevolumeCopy
Turns off the current volume copy operation.
enable storageArray
feature
Activates the Volume Copy premium feature.
recopy volumeCopy Re-initiates a volume copy operation using an
existing volume copy pair.
remove volumeCopy Removes a volume copy pair.
set volumeCopy Defines the properties for a volume copy pair.
show volumeCopy Returns information about volume copy
operations. You can retrieve information
about a specific volume copy pair, or all of the
volume copy pairs in the storage array.
show volumeCopy
sourceCandidates
Returns information about the candidate
volumes that you can use as the source for a
volume copy operation.
show volumeCopy
targetCandidates
Returns information about the candidate
volumes that you can use as the target for a
volume copy operation.
stop volumeCopy Stops a volume copy operation.
Creating a Volume Copy
Before you create a volume copy, make sure that a suitable target volume exists on the storage array, or
create a new target volume specifically for the volume copy. The target volume that you use must have a
capacity equal to or greater than the source volume.
You can have a maximum of eight volume copies with a status of In Progress at one time. Any volume copy
greater than eight has a status of Pending until one of the volume copies with a status of In Progress has
completed the volume copy process.
To create a volume copy, perform these general steps:
1. Enable the Volume Copy premium feature.
2. Determine the candidates for a volume copy.
3. Create the target volume and the source volume for the volume copy.

Enabling the Volume Copy Premium Feature
The first step in creating a volume copy is to make sure that the feature is enabled on the storage array.
Because Volume Copy is a premium feature, you need a Feature Key file to enable the feature. This
command enables the Feature Key file:
enable storageArray feature file=”filename”
where the file parameter is the complete file path and file name of a valid Feature Key file. Enclose the file
path and file name in double quotation marks (“ ”). Valid file names for Feature Key files usually end with a
.key extension.
Determining Volume Copy Candidates
All volumes and drives might not be available for use in volume copy operations. To determine which
candidate volumes on the storage array that you can use as a source volume, use the commands in the
following table.
Action Use This CLI Command
Determine which candidate volumes
on the storage array you can use as a
source volume
show volumeCopy
sourceCandidates
Determine which candidate volumes
on the storage array you can use as a
target volume
show volumeCopy
targetCandidates
The show volumeCopy sourceCandidates command and the show volumeCopy
targetCandidates command return a list of the drive tray, slot, and capacity information for the source
volume candidates and the target volume candidates.
You can use the show volumeCopy sourceCandidates command and the show volumeCopy
targetCandidates command only after you have enabled the Volume Copy premium feature.
Creating a Volume Copy
ATTENTION Possible loss of data access – A volume copy overwrites data on the target volume.
Make sure that you no longer need the data or have backed up the data on the target volume before you start
a volume copy operation.
When you create a volume copy, you must define which volumes that you want to use for the source volume
and the target volume. You define the source volume and the target volume by the name of each volume.
You can also define the copy priority and choose whether you want the target volume to be read only after the
data is copied from the source volume.
The command has this form:
create volumeCopy
source=”sourceName” target=”targetName”
[copyPriority=(highest | high | medium | low | lowest)
targetReadOnlyEnabled=(TRUE | FALSE)]
Before you run the create volumeCopy command, perform these actions:
SANtricity_10.77 February 2011
LSI Corporation
- 1311 -
Stop all I/O activity to the source volume and the target volume.
Dismount any file systems on the source volume and the target volume, if applicable.
This example shows the create volumeCopy command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “create volumeCopy source=\”Jaba_Hut\” target=\”Obi_1\”
copyPriority=medium targetrReadOnlyEnabled=TRUE;”
The command in this example copies the data from the source volume named Jaba_Hut to the target volume
named Obi_1. Setting the copy priority to medium provides a compromise between how quickly the data is
copied from the source volume to the target volume and the amount of processing resources that are required
for data transfers to other volumes in the storage array. Setting the targetReadOnlyEnabled parameter to
TRUE means that write requests cannot be made to the target volume, making sure that the data on the target
volume stays unaltered.
This example shows how to use the command in a script file:
create volumeCopy source=”Jaba_Hut” target=”Obi_1”
copyPriority=medium targetReadOnlyEnabled=TRUE;
After the volume copy operation is completed, the target volume automatically becomes read only to hosts.
Any write requests to the target volume are rejected, unless you disable the Read-Only attribute by using the
set volumeCopy command.
To view the progress of a volume copy, use the show volume actionProgress command. This
command returns information about the volume action, the percentage completed, and the time remaining
until the volume copy is complete.
Viewing Volume Copy Properties
Use the show volumeCopy command to view information about one or more selected source volumes or
target volumes. This command returns these values:
The role
The copy status
The start time stamp
The completion time stamp
The copy priority
The Read-Only attribute setting for the target volume
The source volume World Wide Identifier (WWID) or the target volume WWID
If a volume is participating in more than one volume copy (it can be a source volume for one volume
copy operation and a target volume for another volume copy operation), the details are repeated for each
associated copy pair.
The command has this form:
show volumeCopy (allVolumes | source [sourceName] |
target [targetName])
This example shows the show volumeCopy command:
SANtricity_10.77 February 2011

- 1312 -
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “show volumeCopy source [\”JabaHut\”];”
The command in this example is requesting information about the source volume Jaba_Hut. If you wanted
information about all of the volumes, you would use the allVolumes parameter. You can also request
information about a specific target volume.
This example shows how to use the command in a script file:
show volumeCopy source [“Jaba_Hut”];
Changing Volume Copy Settings
The set volumeCopy command lets you change these property settings for a volume copy pair:
The copy priority
The target volume read/write permission
Copy priority has five relative settings ranging from highest to lowest. The highest priority supports the volume
copy, but I/O activity might be affected. The lowest priority supports I/O activity, but the volume copy takes
longer. You can change the copy priority at these times:
Before the volume copy operation starts
While the volume copy operation has a status of In Progress
After the volume copy operation has completed when re-creating a volume copy operation by using the
recopy volumeCopy command
When you create a volume copy pair and after the original volume copy has completed, the target volume is
automatically defined as read-only to the hosts. The read-only status of the target volume helps to make sure
that the copied data on the target volume is not corrupted by additional writes to the target volume after the
volume copy is created. You want to maintain the read-only status when you are performing these tasks:
Using the target volume for backup purposes
Copying data from one volume group to a larger volume group for greater accessibility
Planning to use the data on the target volume to copy back to the base volume in case of a disabled
snapshot volume or failed snapshot volume
At other times, you might want to write additional data to the target volume. You can use the set
volumeCopy command to reset the read/write permission for the target volume.
NOTE If you have set the volume copy parameters to enable host writes to the target volume, the read
request and the write request to the target volume are rejected while the volume copy operation has a status
of In Progress, Pending, or Failed.
The command has this form:
set volumeCopy target [targetName] [source [sourceName]]
copyPriority=(highest | high | medium | low | lowest)
targetReadOnlyEnabled=(TRUE | FALSE)
NOTE You can use the parameters as needed to help define your configuration.

This example shows the set volumeCopy command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “set volumeCopy target [\”Obi_1\”]
copyPriority=highest
targetReadOnlyEnabled=FALSE;”
This example shows how to use the command in a script file:
set volumeCopy target [“Obi_1”] copyPriority=highest
targetReadOnlyEnabled=FALSE;
Recopying a Volume
Use the recopy volumeCopy command to create a new volume copy for a previously defined copy pair that
has a status of Stopped, Failed, or Completed. You can use the recopy volumeCopy command to create
backups of the target volume. Then, you can copy the backup to tape for off-site storage. When you use the
recopy volumeCopy command to make a backup, you cannot write to the source volume while the recopy
operation is running. The recopy operation might take a long time.
When you run the recopy volumeCopy command, the data on the source volume is copied in its entirety to
the target volume.
ATTENTION Possible loss of data access – The recopy volumeCopy command overwrites
existing data on the target volume and makes the target volume read-only to hosts. The recopy
volumeCopy command fails all of the snapshot volumes that are associated with the target volume, if any
exist.
You can also reset the copy priority by using the recopy volumeCopy command if you want to change the
copy priority for the recopy operation. The higher priorities allocate storage array resources to the volume
copy at the expense of storage array performance.
The command has this form:
recopy volumeCopy target [targetName] [source [sourceName]
copyPriority=(highest | high | medium | low | lowest)
targetReadOnlyEnabled=(TRUE | FALSE)]
NOTE You can use the optional parameters as needed to help define your configuration.
This example shows the show volumeCopy command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “recopy volumeCopy target [\”Obi_1\”] copyPriority=highest;”
The command in this example copies data from the source volume that is associated with the target volume
Obi_1 to the target volume again. The copy priority is set to the highest value to complete the volume copy as
quickly as possible. The underlying consideration for using this command is that you have already created the
volume copy pair, which has already created one volume copy. By using this command, you are copying the
data from the source volume to the target volume with the assumption that the data on the source volume has
changed since the previous copy was made.
This example shows you how to use the command in a script file:
SANtricity_10.77 February 2011

- 1314 -
recopy volumeCopy target [“Obi_1”] copyPriority=highest;
Stopping a Volume Copy
The stop volumeCopy command lets you stop a volume copy that has a status of In Progress, Pending, or
Failed. After you have stopped a volume copy, you can use the recopy volumeCopy command to create
a new volume copy by using the original volume copy pair. After you stop a volume copy operation, all of the
mapped hosts will have write access to the source volume.
The command has this form:
stop volumeCopy target [targetName] [source [sourceName]]
This example shows the show volumeCopy command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “stop volumeCopy target [\”Obi_1\”];”
This example shows how to use the command in a script file:
stop volumeCopy target [“Obi_1”];
Removing Copy Pairs
The remove volumeCopy command lets you remove a volume copy pair from the storage array
configuration. All of the volume copy-related information for the source volume and the target volume is
removed from the storage array configuration. The data on the source volume or the target volume is not
deleted. Removing a volume copy from the storage array configuration also removes the Read-Only attribute
for the target volume.
IMPORTANT If the volume copy has a status of In Progress, you must stop the volume copy before
you can remove the volume copy pair from the storage array configuration.
The command has this form:
remove volumeCopy target [targetName] [source [sourceName]]
This example shows the remove volumeCopy command:
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-c “remove volumeCopy target [\”Obi_1\”];”
This example shows how to use the command in a script file:
remove volumeCopy target [“Obi_1”];
Interaction with Other Premium Features
You can run the Volume Copy premium feature while running the following premium features:
Storage Partitioning
Snapshot
Remote Volume Mirroring
SANtricity_10.77 February 2011
LSI Corporation
- 1315 -
When you are running the Volume Copy premium feature with other premium features, you must consider
the requirements of other premium features to help make sure that you set up a stable storage array
configuration.
In addition to the premium features, you also can run the Volume Copy premium feature while running
Dynamic Volume Expansion (DVE).
Storage Partitioning
Storage Partitioning is a premium feature that lets hosts share access to volumes in a storage array. You
create a storage partition when you define any of these logical components in a storage array:
A host
A host group
A volume-to-LUN mapping
The volume-to-LUN mapping lets you define which host group or host has access to a particular volume in the
storage array.
After you create a volume copy, the target volume automatically becomes read only to hosts to make sure
that the data is preserved. Hosts that have been mapped to a target volume do not have write access to the
volume, and any attempt to write to the read-only target volume results in a host I/O error.
If you want hosts to have write access to the data on the target volume, use the set volumeCopy command
to disable the Read-Only attribute for the target volume.
Snapshot Volumes
A snapshot is a point-in-time image of a volume. It is usually created so that an application, such as a backup
application, can access the snapshot volume and read the data while the base volume stays online and is
accessible to hosts.
The volume for which the point-in-time image is created is known as the base volume and must be a standard
volume in the storage array. The snapshot repository volume stores information about all of the data that
changed since the snapshot was created.
You can select snapshot volumes as the source volumes for a volume copy. This selection is a good use of
this premium feature, because it performs complete backups without significant impact to the storage array I/
O. Some I/O processing resources are lost to the copy operation.
IMPORTANT If you choose the base volume of a snapshot volume as your target volume, you must
disable all of the snapshot volumes that are associated with the base volume before you can select it as a
target volume.
When you create a snapshot volume, a snapshot repository volume is automatically created. The snapshot
repository volume stores information about the data that has changed since the snapshot volume was
created. You cannot select a snapshot repository volume as a source volume or a target volume in a volume
copy.
You can use the Snapshot Volume premium feature with the Volume Copy premium feature to back up data
on the same storage array and to restore the data on the snapshot volume back to its original base volume.

Remote Volume Mirroring
The Remote Volume Mirroring premium feature provides for online, real-time replication of data between
storage arrays over a remote distance. In the event of a disaster or a catastrophic failure of one storage array,
you can promote a secondary storage array to take over responsibility for data storage.
When you create a remote mirror, a remote-mirror pair is created, which consists of a primary volume at the
primary storage array and a secondary volume at a remote storage array.
The primary volume is the volume that accepts host I/O and stores data. When the mirror relationship is
initially created, data from the primary volume is copied in its entirety to the secondary volume. This process
is known as a full synchronization and is directed by the controller owner of the primary volume. During a full
synchronization, the primary volume remains fully accessible for all normal I/O activity.
The controller owner of the primary volume starts remote writes to the secondary volume to keep the data
on the two volumes synchronized. Whenever the data on the primary volume and the secondary volume
becomes unsynchronized, the controller owner of the primary volume starts a resynchronization, where only
the data that changed during the interruption is copied.
The secondary volume maintains a mirror of the data on its associated primary volume. The controller owner
of the secondary volume receives remote writes from the controller owner of the primary volume but does not
accept host write requests.
The secondary volume stays available to host applications as read-only while mirroring is underway. In the
event of a disaster or a catastrophic failure at the primary site, you can perform a role reversal to promote the
secondary volume to a primary role. Hosts are then able to access the newly promoted volume, and business
operations can continue.
You can select a primary volume that is participating in a remote-mirror pair to be used as the source volume
or a target volume for a volume copy. A secondary volume that is participating in a remote-mirror pair cannot
be selected as a source volume or a target volume.
Role Reversals
A role reversal is the act of promoting the secondary volume to be the primary volume of the remote-mirror
pair, and demoting the primary volume to be the secondary volume.
In the event of a disaster at the storage array that contains the primary volume, you can fail over to the
secondary site by performing a role reversal to promote the secondary volume to the primary volume role.
This action lets hosts continue to access data, and business operations can continue.
Trying a role reversal in which the original primary volume is the source volume for an active volume copy
(the status is In Progress or Pending) causes the volume copy to fail. The failure occurs when the original
primary volume becomes the new secondary volume. You cannot restart the volume copy until you return the
roles of the volumes back to their original state; that is, the volume that was originally the primary volume is
set once again to be the primary volume.
If the primary storage array is recovered but is unreachable due to a link failure, a forced promotion of the
secondary volume will result in both the primary volume and the secondary volume viewing themselves in the
primary volume role (dual-primary condition). If this condition occurs, the volume copy in which the primary
volume is participating is unaffected by the role change.
You can perform a role reversal by using the set remoteMirror command.

Maintaining a Storage Array
Maintenance covers a broad spectrum of activity with the goal of keeping a storage array operational and
available to all hosts. This chapter provides descriptions of commands you can use to perform storage array
maintenance. The commands are organized into four sections:
Routine maintenance
Performance tuning
Troubleshooting and diagnostics
Recovery operations
The organization is not a rigid approach, and you can use the commands as appropriate for your storage
array. The commands listed in this chapter do not cover the entire array of commands you can use for
maintenance. Other commands, particularly the set commands, can provide diagnostic or maintenance
capabilities.
Routine Maintenance
Routine maintenance involves those tasks that you might perform periodically to make sure that the storage
array is running as well as possible or to detect conditions before they become problems.
Running a Media Scan
Media scan provides a way of detecting drive media errors before they are found during a normal read from
or write to the drives. Any media scan errors that are detected are reported to the Event Log. The Event Log
provides an early indication of an impending drive failure and reduces the possibility of encountering a media
error during host operations. A media scan is performed as a background operation and scans all data and
redundancy information in defined user volumes.
A media scan runs on all of the volumes in the storage array that have these conditions:
Has Optimal status
Has no modification operations in progress
Has media scan enabled
Errors that are detected during a scan of a user volume are reported to the Major Event Log (MEL) and
handled as follows:
Unrecovered media error – The drive could not read the requested data on its first try or on any
subsequent retries. The result of this action is that for volumes with redundancy protection, the data is
reconstructed, rewritten to the drive, and verified, and the error is reported to the Event Log. For volumes
without redundancy protection, the error is not corrected, but it is reported to the Event Log.
Recovered media error – The drive could not read the requested data on its first attempt. The result of
this action is that the data is rewritten to the drive and verified. The error is reported to the Event Log.
Redundancy mismatches – Redundancy errors are found, and a media error is forced on the block
stripe so that it is found when the drive is scanned again. If redundancy is repaired, this forced media
error is removed. The result of this action is that the first 10 redundancy mismatches found on a volume
are reported to the Event Log.
Unfixable error – The data could not be read, and parity information or redundancy information could not
be used to regenerate it. For example, redundancy information cannot be used to reconstruct data on a
degraded volume. The result of this action is that the error is reported to the Event Log.
SANtricity_10.77 February 2011
LSI Corporation
- 1319 -
The script command set provides two commands to define media scan properties:
set volume
set storageArray
The set volume command enables a media scan for the volume. The command has this form:
set (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN] |
volume <wwID>)
mediaScanEnabled=(TRUE | FALSE)
The set storageArray command defines how frequently a media scan is run on a storage array. The
command has this form:
set storageArray mediaScanRate=(disabled | 1-30)
The mediaScanRate values define the number of days over which the media scan runs. Valid values are
disabled, which turns off the media scan; or 1 day to 30 days, where 1 day is the fastest scan rate, and 30
days is the slowest. A value other than what is shown will not allow the media scan to function.
Running a Redundancy Check
Redundancy checks are performed when media scans are run. (For a description about how to set up and run
media scans, see “Running a Media Scan.“) During a redundancy check, all of the data blocks in a volume
are scanned, and, depending on the RAID level, deteriorated data is corrected. Correction is performed as
follows:
For RAID Level 3, RAID Level 5, or RAID Level 6 volumes, redundancy is checked and repaired.
For RAID Level 1 volumes, the data is compared between the mirrored drives and data inconsistencies
are repaired.
RAID Level 0 volumes have no redundancy.
Before you can run a redundancy check, you must enable redundancy checking by using the set volume
command. The command has this form:
set (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN] |
volume <wwID>)
redundancyCheckEnabled=(TRUE | FALSE)
Resetting a Controller
IMPORTANT When you reset a controller, the controller is no longer available for I/O operations until
the reset is complete. If a host is using volumes that are owned by the controller being reset, the I/O that is
directed to the controller is rejected. Before resetting the controller, either make sure that the volumes that are
owned by the controller are not in use, or make sure that a multi-path driver is installed on all of the hosts that
are using these volumes.
Resetting a controller is the same as rebooting the controller processors. To reset a controller, use this
command:
reset controller [(a | b)]

Enabling a Controller Data Transfer
At times, a controller might become quiescent while running diagnostics. If this condition occurs, the controller
might become unresponsive. To revive a controller that has become quiescent while running diagnostics, use
this command:
enable controller [(a | b)] dataTransfer
Resetting the Battery Age
After you have replaced the batteries in the storage array, you must reset the age of the battery. You can
reset either the batteries for an entire storage array or a battery in a specific controller. To reset the age of the
batteries to zero days, use this command:
reset storageArray batteryInstallDate [controller=(a | b)]
NOTE This command is supported only by controller trays and controller-drive trays released before the
CE6998 controller tray. The batteries in controller trays and controller-drive trays released after the CE6998
controller tray do not require that you reset the battery age after you have replaced the batteries.
Removing Persistent Reservations
Persistent reservations preserve volume registrations, and they prevent hosts, other than the host defined
for the volume, from accessing the volume. You must remove persistent reservations before you make these
changes to your configuration:
Change or delete LUN mappings on a volume holding a reservation
Delete volume groups or volumes that have any reservations
To determine which volumes have reservations, use this command:
show (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN]) reservations
To clear persistent volume reservations, use this command:
clear (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN]) reservations
Synchronizing the Controller Clocks
To synchronize the clocks on both controllers in a storage array with the host clock, use this command:
set storageArray time
Locating Drives
At times, you might need to locate a specific drive. In very large storage array configurations, this task can
sometimes be awkward. If you need to locate a specific drive, you can do so by turning on the indicator light
on the front of the drive. To locate a drive, use this command:
start drive [trayID,slotID] locate
To turn off the indicator light after locating the drive, use this command:

Relocating a Volume Group
Volume group relocation describes the action of moving drives within the same storage array. This is a
supported capability; however, any relocation of storage array components must be completed under the
guidance of your Customer and Technical Support representative.
This section describes the commands that you use to remove a set of drives and then reinstall them into a
different storage array.
Hot and Cold Volume Group Relocation
There are two methods you can use to move volume groups: hot volume group relocation and cold volume
group relocation.
Hot volume group relocation lets you add or move storage without reconfiguring the storage array and, in
some cases, without rebooting. During hot volume group relocation, the storage array power is not turned
off.
Cold volume group relocation requires that the power to the source storage array and the destination
storage array be turned off before moving the volume groups from one storage array to another. Then the
power to the storage arrays can be turned on.
To make sure that any volume group being moved to a different destination storage array is correctly
recognized and managed by the new storage array, use hot volume group relocation whenever possible.
ATTENTION Possible loss of data access – You must move a single volume group at a time, and it
must go into a storage array with the same level of controller firmware.
Basic Process Steps
Relocating a volume group includes these procedures:
1. Verifying the status of the storage array
2. Locating the drives in the volume group
3. Placing the volume group offline
4. Removing drives from the storage array
5. Replacing a volume group into the new storage array
To perform these steps, you must be familiar with the following CLI commands. The command syntax is
provided to assist in your use of these new commands.
Volume Group Relocation Commands
Use the following command to place a specific storage array into an exported state so that its drives can be
removed.
start volumeGroup [volumeGroupName] export
At this point you are allowed to remove the drives that comprise the volume group, and physically reinstall
them into a different storage array.
SANtricity_10.77 February 2011
LSI Corporation
- 1322 -
Use the following command to logically move a specific storage array from an exported state to the complete
state.
start volumeGroup [volumeGroupName] import
Your relocated volume group is now available for use.
For additional information, refer to these commands in the Command Line Interface and Script Commands
for Version 10.75:
show volumeGroup exportDependencies
show volumeGroup importDependencies
show volumeGroup export
show volumeGroup import
Performance Tuning
Over time, as a storage array exchanges data between the hosts and the drives, its performance can
degrade. You can monitor the performance of a storage array and make adjustments to the operational
settings on the storage array to help improve performance.
Monitoring the Performance
You can monitor the performance of a storage array by using the save storageArray
performanceStats command. This command saves performance information to a file that you can review
to help determine how well the storage array is running. The following table lists the performance information
that is saved to the file.
Information About Storage Array Performance
Type of Information Description
Devices These devices are included in the file:
Controllers – The controller in slot A or slot B and a list of
the volumes that are owned by the controller
Volumes – A list of the volume names
Storage array totals – A list of the totals for both
controllers in an active/active controller pair, regardless if
one, both, or neither are selected for monitoring
Total I/Os The number of total I/Os performed since the storage array
was started
Read Percentage The percentage of total I/Os that are read operations
(calculate the write percentage by subtracting the read
percentage from 100 percent)
Cache Hit
Percentage The percentage of reads that are fulfilled by data from the
cache rather than requiring an actual read from a drive
SANtricity_10.77 February 2011
LSI Corporation

Type of Information Description
Current KB per
second The current transfer rate in kilobytes per second (current
means that the number of kilobytes per second since the last
time that the polling interval elapsed, causing an update to
occur)
Maximum KB per
second The highest data transfer value that is achieved in the current
kilobyte-per-second statistic block
Current I/O per
second (IOPS) The current number of I/Os per second (current means the
number of I/Os per second since the last time that the polling
interval elapsed, causing an update to occur)
Maximum I/O per
second The highest number of I/Os achieved in the current I/O-per-
second statistic block
The command takes this form:
save storageArray performanceStats file=”filename”
where filename is the name of the file in which you want to save the performance statistics. You can
use any file name that your operating system can support. The default file type is .csv. The performance
information is saved as a comma-delimited file.
Before you use the save storageArray performanceStats command, run these commands to specify
how often statistics are collected.
set session performanceMonitorInterval
set session performanceMonitorIterations
Changing the RAID Levels
When you create a volume group, you can define the RAID level for the volumes in that volume group. You
can change the RAID level later to improve performance or provide more secure protection for your data.
NOTE RAID Level 6 is a premium feature for the CDE3992 controller-drive tray, CDE3994 controller-
drive tray, and the CDE4900 controller-drive tray. You must enable RAID Level 6 with the feature key file
before you can use the Dynamic RAID-level Migration feature.
To change the RAID level, use this command:
set volumeGroup [volumeGroupNumber]
raidLevel=(0 | 1 | 3 | 5 | 6)
In this command, volumeGroupNumber is the number of the volume group for which you want to change the
RAID level.
Changing the Segment Size
When you create a new volume, you can define the segment size for that volume. In addition, you can change
the segment size later to optimize performance. In a multiuser database or file system storage environment,
set your segment size to minimize the number of drives that are needed to satisfy an I/O request. Use
larger values for the segment size. Using a single drive for a single request leaves other drives available to
SANtricity_10.77 February 2011
LSI Corporation
- 1324 -
simultaneously service other requests. If the volume is in a single-user large I/O environment, performance is
maximized when a single I/O request is serviced with a single data stripe; use smaller values for the segment
size. To change the segment size, use this command:
set volume ([volumeName] | <wwID>) segmentSize=segmentSizeValue
where segmentSizeValue is the new segment size that you want to set. Valid segment size values are 8,
16, 32, 64, 128, 256, and 512. You can identify the volume by name or by WWID. (For usage information,
refer to the set volume command in the Command Line Interface and Script Commands for Version 10.75.)
Changing the Cache Parameters
The script command set provides two commands that you can use to change cache parameter settings:
set storageArray
set volume
The set storageArray command lets you change settings for these items:
The cache block size
The cache flush start percentage
The cache flush stop percentage
The set volume command lets you change settings for these items:
The cache flush modifier
The cache without batteries enabled or disabled
The mirror cache enabled or disabled
The read cache enabled or disabled
The write cache enabled or disabled
The read ahead multiplier
The redundancy check enabled or disabled
Defragmenting a Volume Group
When you defragment a volume group, you consolidate the free capacity in the volume group into one
contiguous area. Defragmentation does not change the way in which the data is stored on the volumes. As
an example, consider a volume group with five volumes. If you delete volume 1 and volume 3, your volume
group is configured as follows:
space, volume 2, space, volume 4, volume 5, original unused space
When you defragment this volume group, the space (free capacity) is consolidated into one contiguous
location after the volumes. After being defragmented, the volume group appears as follows:
volume 2, volume 4, volume 5, consolidated unused space
To defragment a volume group, use this command:
start volumeGroup [volumeGroupNumber] defragment
where volumeGroupNumber is the identifier for the volume group.

Troubleshooting and Diagnostics
If a storage array exhibits abnormal operation or failures, you can use the commands that are described in
this section to help determine the cause of the problem.
Detailed Error Reporting
Data collected from an error encountered by the CLI is written to a file. Detailed error reporting under the CLI
works as follows:
If the CLI must abnormally end running CLI commands and script commands, error data is collected and
saved before the CLI finishes.
The CLI saves the error data by writing the data to a standard file name.
The CLI automatically saves the data to a file. Special command line options are not required to save the
error data.
You are not required to perform any action to save the error data to a file.
The CLI does not have any provision to avoid over-writing an existing version of the file that contains error
data.
For error processing, errors appear as two types:
Terminal errors or syntax errors that you might enter
Exceptions that occur as a result of an operational error
When the CLI encounters either type of error, the CLI writes information that describes the error directly to
the command line and sets a return code. Depending on the return code, the CLI also might write additional
information about which terminal caused the error. The CLI also writes information about what it was
expecting in the command syntax to help you identify any syntax errors that you might have entered.
When an exception occurs while a command is running, the CLI captures the error. At the end of processing
the command (after the command processing information has been written to the command line), the CLI
automatically saves the error information to a file.
The name of the file to which error information is saved is excprpt.txt. The CLI tries to place the
excprpt.txt file in the directory that is specified by the system property devmgr.datadir. If for any
reason the CLI cannot place the file in the directory specified by devmgr.datadir, the CLI saves the
excprpt.txt file in the same directory from which the CLI is running. You cannot change the file name or
the location. The excprpt.txt file is overwritten every time that an exception occurs. If you want to save the
information in the excprpt.txt file, you must copy the information to a new file or a new directory.
Collecting All Support Data
To gather the most comprehensive information about a storage array, run the save storageArray
supportData command. This command collects data for remote troubleshooting and analysis of problems
with the storage management software. All of the files gathered are compressed into a single archive in a
zipped file format. The following table lists the type of support data that is collected.

Collecting Drive Data
To gather information about all of the drives in a storage array, use the save allDrives command. This
command collects sense data and saves the data to a file. The sense data consists of statistical information
that is maintained by each of the drives in the storage array.
Diagnosing a Controller
The diagnose controller command provides these tests that help you make sure that a controller is
functioning correctly:
The read test
The write test
The data-loopback test
The read test initiates a read command as it would be sent over an I/O data path. The read test compares
data with a known, specific data pattern, and the read test checks for data integrity and errors. If the read
command is unsuccessful or the data compared is not correct, the controller is considered to be in error and
is placed offline.
SANtricity_10.77 February 2011
LSI Corporation
- 1328 -
The write test initiates a write command as it would be sent over an I/O data path to the diagnostics region
on a specified drive. This diagnostics region is then read and compared to a specific data pattern. If the write
fails or the data compared is not correct, the controller is considered to be in error, and it is failed and placed
offline.
Run the data-loopback test only on controllers that have connections between the controller and the drives.
The test passes data through each controller drive-side channel, out onto the loop, and back again. Enough
data is transferred to determine error conditions on the channel. If the test fails on any channel, this status is
saved so that it can be returned if all of the other tests pass.
For best results, run all three tests after you first install the storage array and any time that you that have
made changes to the storage array or the components that are connected to the storage array (such as hubs,
switches, and host adapters).
A custom data pattern file called diagnosticsDataPattern.dpf is included in the root directory of the
installation CD. You can modify this file, but the file must have these properties to work correctly for the tests:
The file values must be entered in hexadecimal format (00 to FF) with only one space between the
values.
The file must be no larger than 64 bytes in size. Smaller files will work, but larger files can cause an error.
The test results contain a generic, overall status message and a set of specific test results. Each test result
contains these items:
Test (read, write, or data loopback)
Port (read or write)
Level (internal or external)
Status (pass or fail)
Events are written to the Event Log when the diagnostics are started and when testing is completed. These
events help you to evaluate whether diagnostics testing was successful or failed and the reason for the
failure.
Running Read Link Status Diagnostics
Read link status (RLS) error counts refer to link errors that have been detected in the traffic flow of a Fibre
Channel loop. The errors detected are represented as a count (32-bit field) of error occurrences that are
accumulated over time. The counts provide coarse measure of the integrity of the components and devices
on the loop. By analyzing the error counts that are retrieved, you can determine the components or devices
within the Fibre Channel loop that might be experiencing problems communicating with the other devices
on the loop. A high error count for a particular component or device indicates that it might be experiencing
problems and should be given immediate attention.
Error counts are calculated from the current baseline. The baseline describes the error count values for each
type of device in the Fibre Channel loop, either when the controller goes through its start-of-day sequence or
when you reset the baseline. The baseline indicates the difference in error counts from the time the baseline
was established to the time you request the read link status data.
The script command set provides two commands for running RLS diagnostics:
reset storageArray RLSBaseline – Resets the RLS baseline for all devices by setting all of the
counts to 0.
save storageArray RLSCounts – Saves the RLS counters to a file that you can review later. The
default file name is readLinkStatus.csv.
SANtricity_10.77 February 2011
LSI Corporation

Run the reset storageArray RLSBaseline command before you run the save storageArray
RLSBaseline command.
The following table lists the type of data contained by the file that is generated by the save storageArray
RLSBaseline command.
RLS Baseline Data for the Storage Array
Type of Data Description
Devices A list of all devices on the Fibre Channel loop.
The devices appear in channel order. Within each channel,
the devices are sorted according to the device position in the
loop.
Baseline time The date and time when the baseline was set.
Elapsed time The time that has elapsed from when the baseline time was
set to when the read link status was gathered.
Invalid transmission
word (ITW) The total number of ITW errors that were detected on the
Fibre Channel loop from the baseline time to the current date
and time. ITW might also be referred to as the Received Bad
Character Count.
ITW counts indicate that in decoding a read/write
transmission, the mapping did not exist and the running
disparity of the transmission word is invalid. This data is the
key error count to be used when analyzing the error count
data.
Link failure (LF) The total number of LF errors that were detected on the Fibre
Channel loop from the baseline time to the current date and
time.
An LF condition is either a link fault signal, a loss of signal, or
a loss of synchronization condition. The LF signal indicates a
failure with the media module laser operation.
Loss of
synchronization
(LOS)
The total number of LOS errors that were detected on the
Fibre Channel loop from the baseline time to the current date
and time.
LOS errors indicate that the receiver cannot acquire symbol
lock with the incoming data stream due to a degraded input
signal. If this condition persists, the number of LOS errors
increases.
Loss of signal
(LOSG) The total number of LOSG errors that were detected on the
Fibre Channel loop from the baseline date to the current date
and time.
LOSG errors typically indicate a loss of signal from the
transmitting node or the physical component within the Fibre
Channel loop. Physical components where a loss of signal
typically occurs include the gigabit interface converters
(GBICs), the Small Form-factor Pluggable (SFP) transceivers,
and the Fibre Channel fiber-optic cable.

Type of Data Description
Primitive sequence
protocol (PSP) The total number of PSP errors that were detected on the
Fibre Channel loop from the baseline date to the current date
and time. PSP refers to the number of N_Port protocol errors
that were detected and Link Reset Response (LRR) primitive
sequences that were received while the link is up. An LRR is
issued by another N_Port in response to a link reset.
An N_Port is a Fibre Channel-defined port at the end of a link,
such as a server or a workstation. Each port can act as an
originator or a responder (or both) and contains a transmitter
and receiver. Each port is given a unique name, called an
N_Port or an N_Port identifier. If an N_Port is connected to a
loop, it becomes an NL_Port. An NL_Port is a Fibre Channel
controller ID in a hexadecimal number. The hexadecimal
number varies depending on the topology:
For a private arbitrated loop, the ID is a 1-byte arbitrated
loop physical address (ALPA).
For all other arbitrated loops, it appears as a single 24-bit
hexadecimal number (a triplet of domain, area, and ALPA
where each field is 1 byte).
For fabric and point-to-point, the ID is a 3-byte
hexadecimal number used in the DID and SID (destination
identifier and source identifier) fields of Fibre Channel
frames.
Invalid cyclic
redundancy check
(ICRC)
The total number of ICRC errors that were detected on the
Fibre Channel loop from the baseline date to the current date
and time.
An ICRC count indicates that a frame has been received with
an invalid cyclic redundancy check value. A cyclic redundancy
check reads the data, calculates the cyclic redundancy check
character, and compares the calculated cyclic redundancy
check character with a cyclic check character already present
in the data. If they are equal, the new data is presumed to be
the same as the old data. If the calculated characters and the
old characters do not match, an error is posted, and the data
is re-sent.
Interpreting the RLS Results
The way that you interpret the RLS results is based on the concept that the device immediately following the
problematic component will have the largest number of invalid transition word (ITW) error counts. The process
is to obtain the ITW count for every component and device on the loop, analyze the data in loop order, and
identify any large increases in the ITW counts.
IMPORTANT The current error counting standard for when to calculate the ITW error count is not well
defined. Different vendor devices calculate at different rates. Analysis of the data must take this discrepancy
into consideration.

Collecting Switch-on-a-Chip Error Statistics
Switch-on-a-chip (SOC) error statistics provide information about the loop-switch ports that are connected
to the Fibre Channel devices in a storage array. (RLS counts provide information about the Fibre Channel
devices.) Reporting SOC error statistics is available only on storage arrays that have SOC loop-switch
devices that are incorporated into the controller drive channel or the ESM circuitry. SOC devices are
integrated circuits that join together Fibre Channel devices in arbitrated loop topologies. SOC devices
automatically collect statistical information for each SOC port that is connected to a controller port, an ESM
port, a drive port, or an expansion connector. Your Customer and Technical Support representative can use
the statistical information with RLS counts to identify problems with Fibre Channel devices that are attached
to the loop.
SOC error statics include this information:
The port state
The port insertion count
The loop state
The loop up count
The CRC error count
The relative frequency drift error average
The loop cycle count
The operating system (OS) error count
The port connections attempted count
The port connections held off count
The port utilization
The method for collecting error statistics starts by establishing a baseline for the SOC error statistics. The
baseline consists of SOC error statistics that are established at a set time for each SOC device on the loop.
The baseline is set by clearing the error counters in each SOC device. You can set a device baseline by
performing one of these actions:
Turning on the power to the device or resetting the device
Running the reset storageArray SOCBaseline command
In addition, each controller also initializes the SOC error counters in all of the drive trays that are attached
to the controller following a cold boot (power-on or hot insertion). If you add a drive tray while the power is
turned on to the storage array, a new baseline is established for any device on the drive tray.
After you have established the baseline for the SOC devices, you run the storage array for a predetermined
amount of time (for example, two hours). At the end of the run time, you collect the SOC error statistics
by saving the information to a file. To save the information, run the save storageArray SOCCounts
file filename command. The default name of the file that contains the SOC error statistics is
socStatistics.csv. You can use any file name that has the .csv extension.
Analyzing the SOC error statistics is beyond the scope of normal storage array management. After you
have collected the SOC error statistics in a file, send the file to your Customer and Technical Support
representative.

Recovery Operations
Recovery operations include repairing the storage array and returning it to an operational state. This might
involve replacing a failed canister, a failed controller, or a drive or restoring data or the storage array to
operation. For information about when it is appropriate to replace a canister, see “Routine Maintenance.”
Setting the Controller Operational Mode
A controller has three operational modes:
Online
Offline
Service
Placing a controller online sets it to the Optimal state and makes it active and available for I/O operations.
Placing a controller offline makes it unavailable for I/O operations and moves its volume groups to the other
controller if failover protection is enabled.
Taking a controller offline can seriously impact data integrity and storage array operation.
If you do not use write cache mirroring, data in the cache of the controller you place offline is lost.
If you take a controller offline and you have controller failover protection through a host multi-path
driver, the other controller in the pair takes over. Volume groups and their associated volumes that
were assigned to the offline controller are automatically reassigned to the remaining controller. If you do
not have a multi-path driver installed on the application host and you take a controller offline while the
application is using associated volumes, application errors will occur.
ATTENTION Possible loss of data access – Placing a controller offline can cause loss of data.
Use Service mode to replace canisters, such as a controller. Placing a controller in Service mode makes it
unavailable for I/O operations and moves its volume groups to the second controller without affecting the
preferred path of the volume group. This action might significantly reduce performance. The volume groups
are automatically transferred back to the preferred controller when it is placed back online.
If you change a controller to Service mode while an application is using the associated volumes on the
controller, the change causes I/O errors unless a multi-path driver is installed on the host. Before you place a
controller in Service mode, make sure that the volumes are not in use, or a multi-path driver is installed on all
of the hosts that are using these volumes.
In addition, if you do not have a multi-path driver, you must make appropriate operating system-specific
modifications to make sure that the volume groups moved are accessed on the new path when you change to
Service mode.
IMPORTANT Place a controller in Service mode only under the direction of a Customer and Technical
Support representative.
To change the operational mode of a controller, use this command:
set controller [(a | b)] availability=(online | offline | serviceMode)

Changing the Controller Ownership
You can change which controller is the owner of a volume by using the set volume command. The
command takes this form:
set (allVolumes | volume [volumeName] |
volumes [volumeName1 ... volumeNameN] |
volume <wwID>) owner=(a | b)
Initializing a Drive
ATTENTION Possible loss of data access – When you initialize a drive, all data on the drive is lost.
You must initialize a drive when you have moved a drive that was previously part of a multidisk volume group
from one storage array to another. If you do not move the entire set of drives, the volume group information
and the volume information on the drives that you move are incomplete. Each drive that you move contains
only part of the information that is defined for the volume and the volume group. To be able to reuse the
drives to create a new volume group and volume, you must delete all of the old information from the drives by
initializing the drive.
When you initialize a drive, all of the old volume group information and volume information are deleted, and
the drive is returned to an unassigned state. Returning a drive to an unassigned state adds unconfigured
capacity to a storage array. You can use this capacity to create additional volume groups and volumes.
To initialize a drive, use this command:
start drive [trayID,slotID] initialize
In this command, trayID and slotID are the identifiers for the drive.
Reconstructing a Drive
If two or more of the drives in a volume group have failed, the volume shows a status of Failed. All of the
volumes in the volume group are no longer operating. To return the volume group to an Optimal status, you
must replace the failed drives. Then, you must reconstruct the data on the new drives. The data that you
reconstruct is the data as it would appear on the failed drives.
IMPORTANT You can use this command only when the drive is assigned to a RAID Level 1, RAID
Level 3, RAID Level 5, or RAID Level 6 volume group.
To reconstruct a drive, use this command:
start drive [trayID,slotID] reconstruct
In this command, trayID and slotID are the identifiers for the drive.
Initializing a Volume
ATTENTION Possible loss of data access – When you initialize a volume, all data on the volume
and all of the information about the volume are destroyed.
A volume is automatically initialized when you first create it. If the volume starts showing failures, you might
be required to re-initialize the volume to correct the failure condition.
SANtricity_10.77 February 2011
LSI Corporation

Consider these restrictions when you initialize a volume:
You cannot cancel the operation after it begins.
You cannot use this option if any modification operations are in progress on the volume or the volume
group.
You cannot change the cache parameters of the volume while the initialization operation is in progress.
To initialize a volume, use this command:
start volume [volumeName] initialize
where volumeName is the identifier for the volume.
Redistributing Volumes
When you redistribute volumes, you return the volumes to their preferred controller owners. The preferred
controller ownership of a volume or a volume group is the controller of an active-active pair that is designated
to own the volumes. The preferred owner for a volume is initially designated when the volume is created. If
the preferred controller is being replaced or undergoing a firmware download, ownership of the volumes is
automatically shifted to the other controller. That controller becomes the current owner of the volumes. This
change is considered to be a routine ownership change and is reported in the Event Log.
To redistribute volumes to their preferred controllers, use this command:
reset storageArray volumeDistribution
IMPORTANT If you run this command without a multi-path driver on the hosts, stop I/O activity to the
volumes to prevent application errors.
IMPORTANT You cannot run this command if all of the volumes are currently owned by their preferred
controller, or the storage array does not have defined volumes.
Under some host operating systems, you must reconfigure the multi-path host driver. You might also need to
make operating system modifications to recognize the new I/O path to the volume.
Replacing Canisters
Beginning with the CE6998 controller tray, components, such as the controller canisters, the power-fan
canisters, and the interconnect-battery canisters, have a Service Action Allowed indicator light. This indicator
light is a blue LED. The Service Action Allowed indicator light helps to make sure that you do not remove a
canister before it is safe to do so.
ATTENTION Possible loss of data access – Never remove a component that has a Service Action
Required indicator light on unless the Service Action Allowed indicator light is on.
If a component fails and must be replaced, the Service Action Required indicator light on that canister comes
on to indicate that service action is required, provided no data availability dependencies or other conditions
exist that dictate the canister should not be removed. The Service Action Allowed indicator light automatically
comes on or goes off when conditions change. In most cases, the Service Action Allowed indicator light
comes on steadily when the Service Action Required indicator light comes on for the canister.
SANtricity_10.77 February 2011
LSI Corporation
- 1335 -
If the interconnect-battery canister must be replaced, the Service Action Allowed indicator light does not come
on automatically. Before the Service Action Allowed indicator light on the interconnect-battery canister can
come on, you must place controller canister in slot B into Service mode. This action routes all control and I/O
activity through one controller to help make sure that data access is maintained while the interconnect-battery
canister is removed. The Service Action Allowed indicator light comes on after the new canister has been
installed.
The ability to remove a canister depends on the data availability dependencies of the controller tray or the
controller-drive tray. The Service Action Allowed indicator light does not come on if removing a canister
jeopardizes data on the drive trays or current I/O activity. An example of limiting when you can remove a
canister is when one controller canister has a Service Action Required indicator light on. You cannot remove
the other controller canister (the Service Action Allowed indicator light does not come on), because doing so
would jeopardize the data either on the drive trays or transitioning through the controllers.
A less obvious example is when the power supply for the controller canister in slot A has failed, and the
controller canister in slot B has failed. Removing the controller canister in slot B before replacing the failed
power-fan canister causes the controller canister in slot A to lose power, which results in a loss of data
access. This action occurs because power distribution from each power-fan canister is through the controller
canister that is physically connected to that power-fan canister.
So, in the preceding example, these actions occur:
The power-fan canister has both its Service Action Required indicator light and its Service Action Allowed
indicator light on.
The controller canister in slot B has only its Service Action Required indicator light on, but its Service
Action Allowed indicator light is off.
After the failed power-fan canister has been replaced, the Service Action Allowed indicator light comes on
for the controller canister in slot B.
The following table shows when the Service Action Allowed indicator light does not come on for each canister
(the indicator light is suppressed). An X in a table cell indicates that service is not allowed, therefore the
Service Action Allowed light does not come on. For example, if the power supply in the power-fan canister in
slot A has failed, then replacement of the controller canister in slot B, the interconnect-battery canister, or the
power-fan canister in slot B is not allowed, which is indicated when the Service Action Allowed indicator light
stays off for those canisters.

Example Script Files
This appendix provides example scripts for configuring a storage array. These examples show how the script
commands appear in a complete script file. Also, you can copy these scripts and modify them to create a
configuration unique to your storage array.
You can create a script file in two ways:
Using the save storageArray configuration command
Writing a script
By using the save storageArray configuration command, you can create a file that you can use
to copy an existing configuration from one storage array to other storage arrays. You can also use this file
to restore an existing configuration that has become corrupted. You also can copy an existing file to serve
as a pattern from which you create a new script file by modifying portions of the original file. The default file
extension is .scr.
You can create a new script file by using a text editor, such as Microsoft Notepad. The maximum line length is
256 characters. The command syntax must conform to the guidelines in the topic "About the Command Line
Interface" and the topic "About the Script Commands. When you create a new script file, you can use any file
name and extension that will run on the host operating system.
This example shows how to run a script file from the command line.
c:\...\smX\client>smcli 123.45.67.88 123.45.67.89
-f scriptfile.scr;
Configuration Script Example 1
This example creates a new volume by using the create volume command in the free space of a volume
group.
Show “Create RAID 5 Volume 7 on existing Volume Group 1”;
//Create volume on volume group created by the create
volume drives command
//Note: For volume groups that use all available
capacity, the last volume on the group is created using
all remaining capacity by omitting the capacity=volume
creation parameter
create volume volumeGroup=1 RAIDLevel=5 userLabel=”7”
owner=A segmentSize=16 cacheReadPrefetch=TRUE capacity=2GB;
show “Setting additional attributes for volume 7”;
//Configuration settings that cannot be set during volume
creation
set volume[“7”] cacheFlushModifier=10;
set volume[“7”] cacheWithoutBatteryEnabled=false;
set volume[“7”] mirrorEnabled=true;
set volume[“7”] readCacheEnabled=true;
set volume[“7”] writeCacheEnabled=true;
set volume[“7”] mediaScanEnabled=false;
set volume[“7”] redundancyCheckEnabled=false;
SANtricity_10.77 February 2011
LSI Corporation
- 1373 -
set volume[“7”] modificationPriority=high;
This example shows blank lines between the lines beginning with Show, Create, //Note, and create. The
blank lines are included in this example only for clarity. Each command is actually written on one line in the
script file; however, the size of this page has caused the command text to wrap. You might want to include
blank lines in your script files to separate blocks of commands or make a comment that stands out. To include
a comment, enter two forward slashes (//), which causes the Script Engine to treat the line as a comment.
The first line of text is the show string command. This command shows text that is bounded by double
quotation marks (“ ”) on a display monitor when the script file runs. In this example, the text Create RAID
5 Volume 7 on existing Volume Group 1 serves as a title that describes the expected results of
running this script file.
The line beginning with //Create is a comment that explains that the purpose of this script file is to create a
new volume by using the create volume command on an existing volume group.
The line beginning //Note: is a comment in the script file that explains that the size of the last volume
created that uses all of the available capacity because the capacity parameter is not used.
The command in this example creates a new volume in volume group 1. The volume has RAID Level 5.
The volume name (user label) is 7. (Note the double quotation marks around the 7. The double quotation
marks define that the information in the double quotation marks is a label.) The new volume is assigned to
the controller in slot A in the controller tray. The segment size is set to 16. The volume has a read ahead
multiplier value of 256. The capacity of the volume is 2 GB.
The command takes this form:
create volume volumeGroup=volumeGroupNumber
userLabel=volumeName
[freeCapacityArea=freeCapacityIndexNumber]
[capacity=volumeCapacity | owner=(a | b) |
cacheReadPrefetch=(TRUE | FALSE) |
segmentSize=segmentSizeValue]
[trayLossProtect=(TRUE | FALSE)]
The general form of the command shows the optional parameters in a different sequence than the optional
parameters in the example command. You can enter optional parameters in any sequence. You must enter
the required parameters in the sequence shown in the command descriptions.
The line showing “Setting additional attributes for volume 7” is another example of using the
show “string” command. The reason for placing this command here is to tell the user that the create
volume command ran successfully and that properties that could not be set by the create volume
command are now set.
The set volume parameters are shown on separate lines. You do not need to use separate lines for each
parameter. You can enter more than one parameter with the set volume command by leaving a space
between the parameters, as in this example:
set volume[“7”] cacheFlushModifier=10
cacheWithoutBatteryEnabled=false
modificationPriority=high;
By using separate lines, you can see more clearly the parameters that you are setting and the values to which
you are setting the parameters. Blocking the parameters in this manner makes it easier to either edit the file
or copy specific parameter settings for use in another script file.

Configuration Script Example 2
This example creates a new volume by using the create volume command with user-defined drives in the
storage array.
Show “Create RAID3 Volume 2 on existing Volume Group 2”;
//This command creates the volume group and the initial volume on that group.
//Note: For volume groups that use all available capacity, the last volume
on the volume group is created using all remaining capacity by omitting the
capacity=volume creation parameter
create volume RAIDLevel=3 userLabel=”2” drives=[0,1 0,6 1,7 1,3 2,3 2,6]
owner=B segmentSize=16 capacity=2GB;
show “Setting additional attributes for voluem 7”’
//Configuration settings that cannot be set during volume creation
set volume [“7”] cacheFlushModifier=10;
set volume [“7”] cacheWithoutBatteryEnabled=false;
set volume [“7”] mirrorEnabled=true;
set volume [“7”] readCacheEnabled=true;
set volume [“7”] writeCacheEnabled=true;
set volume [“7”] mediaScanEnabled=false;
set volume [“7”] redundantCheckEnabled=false;
set volume [“7”] modificationPriority=high;
The command in this example, like the create volume command in the previous example, creates a new
volume. The significant difference between these two examples is that this example shows how you can
define specific drives to include in the volume. Use the show storageArray profile command to find
out what drives are available in a storage array.
The create volume command takes this form:
create volume raidLevel=(0 | 1 | 3 | 5 | 6) userLabel=volumeName
drives=(trayID1,slotID1...trayIDn,slotIDn)
[capacity=volumeCapacity | owner=(a | b) |
cacheReadPrefetch=(TRUE | FALSE) |
segmentSize=segmentSizeValue]
[trayLossProtect=(TRUE | FALSE)]

Asynchronous Remote Volume Mirroring Utility
This appendix describes the host utility to achieve periodic consistency with Asynchronous Remote Volume
Mirroring configurations. This appendix also describes how to run the Asynchronous Remote Volume
Mirroring utility.
Description of the Asynchronous Remote Volume Mirroring Utility
The Asynchronous Remote Volume Mirroring utility lets you periodically synchronize the Remote Volume
Mirroring pairs in your storage array. When defining a Remote Volume Mirroring configuration, you have the
option to set the write modes to either Synchronous or Asynchronous. Synchronous write mode provides
the highest level security for full data recovery from the secondary storage array in the event of a disaster.
Synchronous write mode does, however, reduce host I/O performance. Asynchronous write mode offers
faster host I/O performance, but it does not guarantee that a copy operation has successfully completed
before processing the next write request. With Asynchronous write mode, you cannot make sure that a
volume, or collection of volumes, at a secondary site ever reach a consistent, recoverable state.
The Asynchronous Remote Volume Mirroring utility enables you to bring a collection of asynchronous
remote volumes into a mutually consistent and recoverable state. You can choose to run the utility based on
application demands, link state and speed, and other factors that are relevant to your environment.
The Asynchronous Remote Volume Mirroring utility has these characteristics:
The utility is implemented as a command line-invoked Java-based application.
The utility is bundled as part of the SANtricity ES Storage Manager installation package.
The utility accepts a command line argument that lets you specify the name of a configuration file that
contains a complete specification of the work to be carried out by the utility.
More than one instance of the utility can run concurrently, as long as the utilities do not try to process any
of the same volumes and mirrors.
NOTE The Asynchronous Remote Volume Mirroring utility does not check to make sure that
concurrently running instances of the utility are not trying to process the same volumes and mirrors. If you
choose to simultaneously run more than one instance of the Asynchronous Remote Volume Mirroring utility,
you must make sure that the configuration files that you choose to run do not list the same volumes and
mirrors.
Operation of the Asynchronous Remote Volume Mirroring Utility
The Asynchronous Remote Volume Mirroring utility performs steps that generate a recoverable state for
multiple mirror volumes at a secondary site. The utility runs these steps to create consistent, recoverable
images of a set of volumes:
1. On the primary storage array – The utility reconfigures all of the participating volumes from
asynchronous mirroring to synchronous mirroring. This action makes sure that the stream of write
operations becomes recoverable on the secondary side.
2. On the primary storage array – The utility polls all of the participating volumes until the associated
mirror states all have the Optimal state. In cases where the remote link is slow or the primary host I/O
activity is high, one or more mirrors are likely to be in the Unsynchronized state before they transition to
the Synchronized state. By waiting until all of the mirrors have Optimal status, the utility makes sure that
all of the delta logs for the affected volumes are cleared, and the secondary volumes are recoverable.
SANtricity_10.77 February 2011
LSI Corporation
- 1376 -
3. On the primary storage array – The utility suspends the mirrored pairs for all of the participating
volumes. This action causes updates to stop on the secondary side, leaving the secondary volumes in
a recoverable state because they were being updated in Synchronous mode immediately before the
suspension. By separating the mirrors in this manner, the primary-side applications run faster, while
leaving the secondary volumes in a recoverable state. The delta log tracks changes made because of
application writes on the primary side while in this state.
4. On the secondary storage array – The utility generates a snapshot of each participating volume on the
secondary side, which creates point-in-time images that are recoverable.
5. On the primary storage array – The utility resumes the mirroring operations for all of the participating
volumes. This action causes the mirrors to transition to the Synchronized state and start the process of
restoring coherency between the primary site and the secondary site.
6. On the primary storage array – The utility reconfigures all of the affected volumes for Asynchronous
mode.
Running the Asynchronous Remote Volume Mirroring Utility
The Asynchronous Remote Volume Mirroring utility uses a command line argument that lets you specify the
name of a configuration file. The configuration file contains a complete specification of the input parameters
that are needed by the utility. To run the utility, enter this syntax:
asyncRVMUtil configuration_file -d debug_file
In this command, configuration_file is the file that you provide as input. The configuration file specifies
the Remote Volume Mirroring volumes that you want to synchronize by using the utility. When you create the
configuration file, use these conditions to define the volumes in the file:
All the primary volumes in a volume set must belong to the same storage array.
The maximum number of volume sets that you can specify in the file is four.
The maximum number of mirrored pairs that you can specify as part of a consistency group is eight.
The optional parameter, -d, lets you specify a file to which you can send information regarding how the utility
runs. In this example, the file name is debug_file. The debug file contains trace information that can be
reviewed by your Customer and Technical Support representative to determine how well the Asynchronous
Remote Volume Mirroring utility has run.
NOTE Depending on the location of the configuration file and the debug file, you must specify the
complete path with the file name.
To run the Asynchronous Remote Volume Mirroring utility, you must enter the asyncRVMUtil command
from the command line. Because UNIX operating systems are case sensitive, you must type the command
exactly as shown. On Windows operating systems, you can type the command in all uppercase, in all
lowercase, or in mixed case.
NOTE To use the Asynchronous Remote Volume Mirroring utility, you must be managing the storage
array by using the command line interface, not the graphical user interface of SANtricity ES Storage Manager.
Configuration Utility
The configuration file is an ASCII flat text file that provides the information for the Remote Volume Mirroring
synchronization used by the Asynchronous Remote Volume Mirroring utility. The file defines the mirror
volume sets to be synchronized. All of the mirror volumes in the volume sets defined in the configuration
SANtricity_10.77 February 2011
LSI Corporation
- 1377 -
file are run collectively to create a recoverable image. If any one of the mirrors in the volume set fails, the
operation is stopped for this volume set and carried on to the next volume set that is listed in the configuration
file.
The configuration file supports this syntax:
content ::= {spec}
spec ::= logSpec | volumeSetSpec
logSpec ::= "Log" "{" {logAttribute} "}"
logAttribute ::= fileSpec
fileSpec ::= "file" "=" fileName
volumeSetSpec ::= "VolumeSet" volumeSetName
"{" {volumeSetAttribute} "}"
volumeSetAttribute ::= timeoutSpec | mirrorSpec
timeoutSpec ::= "OptimalWaitTimeLimit" "=" integer
mirrorSpec ::= "Mirror" "{" {mirrorAttribute} "}"
mirrorAttribute ::= primarySpec | secondarySpec |
snapshotSpec
primarySpec ::= "Primary" "=" volumeSpec
secondarySpec ::= "Secondary" "=" volumeSpec
snapshotSpec ::= "Copy" "=" volumeSpec
volumeSpec ::= storageArrayName"."volumeUserLabel
In this syntax, items enclosed in double quotation marks (“ ”) are terminal symbols. Items separated by a
vertical bar (|) are alternative values (enter one or the other, but not both). Items enclosed in curly braces ({ })
are optional (you can use the item zero or more times).
These definitions are provided for non-terminals in the syntax:
integer – The timeout value must be an integer (decimal digits from 0–9).
volumeSetName – The name of the set of volumes on which you want to run the Asynchronous Remote
Volume Mirroring utility.
fileName – The name of a file, using characters and conventions that are appropriate for the system on
which the application is running.
storageArrayName – The label that you have assigned for a storage array, as would be used in the CLI
to specify the name of the storage array.
volumeUserLabel – The label that you have assigned for a volume that uniquely identifies the volume
within the storage array.
NOTE Names and labels can be any characters that are defined as appropriate for your operating
system. The maximum length for a name or label is 30 characters. If the name or label contains special
characters (as defined by the operating system) or period characters, you must enclose the name or label in
double quotation marks (“ ”). You can, optionally, enclose the name or label in double quotation marks at any
time.
These items are considered syntax errors:
More than one logSpec command in the input file
SANtricity_10.77 February 2011
LSI Corporation
- 1378 -
Zero or more than one fileSpec attribute in a logSpec command (you must include exactly one
fileSpec attribute in the logSpec command)
More than one timeoutSpec attribute in a volumeSetSpec command
Zero or more than one primarySpec attribute in a mirrorSpec command (you must include exactly
one primarySpec attribute in the mirrorSpec command)
Zero or more than one secondarySpec attribute in a mirrorSpec command (you must include exactly
one secondarySpec attribute in the mirrorSpec command)
Zero or more than one snapshotSpec attribute in a mirrorSpec command (you must include exactly
one snapshotSpec attribute in the mirrorSpec command)
IMPORTANT In the Asynchronous Remote Volume Mirroring utility configuration file, you must specify
the primary volume, the secondary volume, and the copy (snapshot) volume. The utility does not make sure
that the secondary volume is correct for the Remote Volume Mirroring relationship. The utility also does not
make sure that the snapshot volume is actually a snapshot for the secondary volume. You must make sure
that these volumes are correct. If the volumes are not correct, the utility will run, but the volumes will not be
consistent. For each mirror, the secondary volume and the copy volume must reside on the same storage
array.
This example shows a configuration file for the Asynchronous Remote Volume Mirroring utility.
Log{ file="d:\rvm-consistency.log" }
VolumeSet "set1" {
optimalWaitTimeLimit = 15
Mirror {
Primary = LosAngelesArray.PayrollVolume
Secondary = NewYorkArray.PayrollVolume
Copy = NewYorkArray.PayrollVolumeImage
}
Mirror {
Primary = LosAngelesArray.PayrollVolume
Secondary = BostonArray.PayrollVolume

}
}

Simplex-to-Duplex Conversion
Some models of controller trays and controller-drive trays are available in either a simplex configuration
(one controller) or a duplex configuration (two controllers). You can convert a simplex configuration to a
duplex configuration by installing new nonvolatile static random access memory (NVSRAM) and a second
controller. This appendix explains how to convert a simplex configuration to a duplex configuration by using
CLI commands or by using the storage management software.
General Steps
You can upgrade a controller tray or a controller-drive tray that has a simplex configuration to a duplex

Step 1 – Installing the Duplex NVSRAM
IMPORTANT Before trying to download NVSRAM, you must contact your Customer and Technical
Support representative to make sure that you are downloading the NVSRAM that is appropriate for the
controller in your storage array.
NVSRAM files specify the default settings for the controller tray controllers or controller-drive tray controllers.
Follow the instructions in this step to upgrade the NVSRAM on the controller in your controller tray or your
controller-drive tray.
To get a copy of the latest NVSRAM, perform one of these tasks:
Download the duplex NVSRAM by using the command line interface.
Download the duplex NVSRAM by using the graphical user interface (GUI) of the storage management
software.
Copy the duplex NVSRAM from the installation CD in the conversion kit.

9. Based on the dialog that appears after the download is completed, perform one of these actions:
Download Successful dialog – Click Done.
Error dialog – Read the information in the dialog, and take the appropriate action.
Step 2 – Setting the Configuration to Duplex
After rebooting the controller tray or the controller-drive tray, an “alternate controller missing” error message
appears. This message indicates that the controller in slot A has successfully converted to Duplex mode. This
message persists until you have completed the tasks to install the second controller, installed the host cables,
and installed the drive tray cables.
1. Start the command line interface.
2. On the command line, type this command, and press Enter. In this command, ctlr-A_IP_address is
the IP address of the of the original simplex controller.
smcli ctlr-A_IP_address -c “set storageArray redundancyMode=duplex;”
3. Reboot the controller tray or the controller-drive tray.
Step 3 – Installing the Second Controller
ATTENTION Possible hardware damage – To prevent electrostatic discharge damage to the tray,
use proper antistatic protection when handling tray components.
IMPORTANT For best operation, the new controller must have a part number identical to the existing
controller, or the new controller must be a certified substitute. The part number is on a label on the controller.
To provide full functionality in dual#controller configurations, make sure that both controllers in the controller
tray or the controller-drive tray have the same memory capacity. Although you can install two controllers of
different memories in a controller tray or a controller-drive tray, the mismatch disables some functions, such
as cache mirroring.
1. Put on antistatic protection.
ATTENTION Possible damage to the controller – Do not remove the electrostatic protection
until you have finished installing the controller and you have connected the host cables and the drive tray
cables.
2. Unpack the new controller.
ATTENTION Possible damage to the controller – Bumping the controller against another
surface might damage the data connectors on the rear of the controller. Use caution when handling the
controller.
3. Remove the blank controller canister from the tray by releasing the handle, and pulling the blank
controller canister out of the tray.
4. Slide the new controller canister into the empty slot by pushing the controller canister until it snaps into
place, and locking the handle into the closed position.

Step 4 – Connecting the Host Cables
The steps in this procedure describe how to attach Fibre Channel host cables. The steps for connecting other
types of host cables are similar, but they do not require the installation of Small Form-factor Pluggable (SFP)
transceivers.
1. If there is a black plastic plug in the host port, remove it.
2. Install an SFP transceiver into the controller by pushing the SFP transceiver into the host port until it
snaps into place.
ATTENTION Possible degraded performance – To prevent degraded performance, do not twist,
fold, pinch, or step on fiber-optic cables. Do not bend fiber-optic cables tighter than a 5#cm (2-in.) radius.
3. Plug one end of the fiber-optic cable into the SFP transceiver in the host port.
4. Plug the other end of the fiber-optic cable into one of the HBAs in the host (direct topology) or into a
switch (switch topology).
5. Attach a label to each end of the cable by using this scheme. A label is very important if you need to
disconnect the cables later to service a controller.
The host name and the host bus adapter (HBA) port (if direct topology)
The switch name and port (if switch topology)
The controller ID (for example, controller A)
The host channel ID (for example, host channel 1)
Example label abbreviation – Assume that a cable is connected between port 1 in HBA 1 of a host
named Engineering and host channel 1 of controller A. A label abbreviation could be as follows:
Heng-ABA1/P1, CtA-Hch1
6. Repeat step 1 through step 5 for each host channel that you intend to use.
Step 5 – Connecting the Controller to a Drive Tray
The steps in this procedure describe how to attach Fibre Channel cables to a drive tray. The steps for
connecting other types of drive tray cables are similar, but they do not require the installation of SFP
transceivers.
1. If there is a black plastic plug in the drive port of the new controller canister, remove it.
2. Insert an SFP transceiver into the drive port on a controller canister.
3. Plug one end of the cable into the SFP transceiver.
4. Plug the other end of the cable into the appropriate in port or out port on the environmental services
monitor (ESM) in the drive tray as applicable for your cabling configuration.
5. Attach a label to each end of the cable by using this scheme. A label is very important if you need to
disconnect the cables later to service a controller.
The controller ID (for example, controller A)
The drive channel number and port ID (for example, drive channel 1, port 2)
The ESM ID (for example, ESM A)
The ESM port ID (for example, In, Out, 1A, or 1B)
The drive tray ID

Example label abbreviation – Assume that a cable is connected between drive channel 1, port 2 of
controller A to the out port of the left ESM (A) in drive tray 1. A label abbreviation could be as follows:
CtA-Dch1/P2, Dm1-ESM_A (left), Out
6. Repeat step 1 through step 5 for each drive tray.
7. Remove the antistatic protection.
Step 6 – Running Diagnostics
1. Using the LEDs on the storage array and information provided by the storage management software,
check the status of all trays in the storage array.
2. Does any component have a Needs Attention status?
Yes – Click the Recovery Guru toolbar button in the Array Management Window, and complete
the recovery procedure. If a problem is still indicated, contact your Customer and Technical Support
representative.
No – Go to step 3.
3. Create, save, and print a new storage array profile.
