1 Enterprise Virtual Array
description
This chapter provides an overview of Enterprise Virtual Array and its components.
Introduction to the Enterprise Virtual Array
The HP StorageWorks Enterprise Virtual Array family is a high performance, scaled capacity, on demand,
"virtual" RAID storage system.
This storage system is designed for environments where improved storage use and scalability is critical. It
meets application-specific demands for consistently high transaction I/O (input/output) and MB data
rate performance, and provides seamless capacity expansion, instantaneous replication, and simplified
storage administration.
The Enterprise Virtual Array (EVA) is available in multiple configurations—each optimized for
general-purpose commercial environments and high-performance technical computing environments. The
solutions include support for multivendor operating system platforms and stringent data center availability
enhancements, such as multipathing and clustering.
This guide includes information for two Enterprise Virtual Array products: EVA5000 and EVA3000.
•EVA5000—available in multiple configurations ranging from the single-rack 2C2D configuration
to the multi-rack 2C18D. The EVA5000 includes two HSV110 controllers and four FC loop switches.
•EVA3000—available in configurations ranging from the 2C2D configuration to the 2C4D
configuration. The EVA3000 includes two HSV100 controllers and no loop switches. Multiple
EVA3000s can be installed in a single rack.
Seer the HP StorageWorks Enterprise Virtual Array 3000/5000 hardware configuration guide for more
information about configurations. See “Related documentation” on page 13 for links to this document.
Features and enhancements
The Enterprise Virtual Array provides many features and enhancements which are detailed in the sections
that follow.
Ease of management
Easy-to-use storage management tools:
•Software tools that allow you to manage larger SAN configurations with more servers and more
storage solutions
•HP-supplied disk drives conform to the enclosure-initiated Enclosure Services Interface (ESI)
•State-of-the-art controller software
•Completely integrated configurations with a single part number, plus disk drives and storage

StorageWorks Enterprise Virtual Array configuration best practices white paper available from
http://h71028.www7.hp.com/ERC/downloads/5982-9140EN.pdf.
Operating tips and information
Reservingadequatefreespace
To ensure efficient storage system operation, a certain amount of unallocated capacity, or free space,
should be reserved in each disk group. The recommended amount of free space is influenced by your
system configuration. For guidance on how much free space to reserve, See the HP StorageWorks
Enterprise Virtual Array configuration best practices white paper. See Best practices.
Using FATA disk drives
FATA drives are designed for lower duty cycle applications such as near on-line data replication for
back-up. These drives should not be used as a replacement for EVA’s high performance, standard
duty cycle, Fibre Channel drives. Doing so could shorten the life of the drive. Download the following
document for more information on FATA drives, their uses and benefits:

Powering up the storage system
To power up a storage system, perform the following steps:
1. Verify that each fabric Fibre Channel switch to which the HSV controllers are connected is powered
up and fully booted. The power indicator on each switch should be on.
If you must power up the SAN switches, wait for them to complete their power-on boot process
before proceeding. This may take several minutes.
2. If the management server you shut down is an SMA, power it on and wait for it to completely boot.
Verify the SMA is running by logging into it using the web interface.
NOTE:
Before applying power to the rack, ensure that the power switch on each HSV controller
is off.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 37
3. Power on the circuit breakers on both EVA rack PDUs. Verify that all drive enclosures are operating
properly. The status indicator and the power indicator should be on (green).
4. Wait three minutes and then verify that all disk drives are ready. The drive ready indicator and
the drive online indicator should be on (green).
5. Powerontheuppercontroller. Ittakestherollofmastercontroller.
6. Wait 10 seconds and then power on the lower controller. It takes the roll of slave controller.
7. Verify that the (Operator Control Panel) OCP display on each controller displays the storage system
name and the EVA WWN.
8. Start HP Command View EVA and verify connection to the storage system. If the storage system is
not visible, click HSV Storage Network in the Navigation pane then click Discover in the Content
pane to discover the array.
NOTE:
If the storage system is still not visible, reboot the management server to re-establish the
communication link.
9. Check the storage system status using HP Command View EVA to ensure everything is operating
properly. If any status indicator is not normal, check the log files or contact your HP—authorized
service provider for assistance.
Saving storage system configuration data
As part of an overall data protection strategy, storage system configurationdatashouldsavedduring
initial installation, and whenever major configuration changes are made to the storage system. This
includes adding or removing disk drives, creating or deleting disk groups, and adding or deleting
virtual disks. The saved configuration data can save substantial time should it ever become necessary to
re-initializethestoragesystem.Theconfiguration data is saved to a series of files which should be stored
in a location other than on the storage system.
This procedure can be performed from the SMA or management server where the HP Command View
EVA is installed, or any host that can run the Storage System Scripting Utility (SSSU) to communicate
with the management server.
NOTE:
For more information on using SSSU, see the HP StorageWorks Storage System Scripting Utility reference.
See “Related documentation” on page 13.
1. Double-click on the SSSU desktop icon to run the application. When prompted, enter Manager
(management server name or IP address), User name, and Password.
2. Enter LS SYSTEM to display the EVA storage systems managed by the management server.
3. Enter SELECT SYSTEM system name,wheresystem name isthenameofthestoragesystem.
The storage system name is case sensitive. If there are spaces between the letters in the name, quotes
must enclose the name: for example, SELECT SYSTEM “Large EVA”.
4. Enter CAPTURE CONFIGURATION, specifying the full path and filename of the output files for
the configuration data.
The configuration data is stored in a series of from one to five files, which are SSSU scripts. The file
names begin with the name you select, with the restore step appended. For example, if you specify a
file name of LargeEVA.txt,theresultingconfiguration files would be LargeEVA_Step1A.txt,
LargeEVA_Step1B,etc.
The contents of the configuration files can be viewed with a text editor.
38 Enterprise Virtual Array operation
NOTE:
If the storage system contains disk drives of different capacities, the SSSU procedures used do not
guarantee that disk drives of the same capacity will be exclusively added to the same disk group. If you
need to restore an array configuration that contains disks of different sizes and types, you must manually
recreate these disk groups. The controller software and the utility’s CAPTURE CONFIGURATION
command are not designed to automatically restore this type of configuration. For more information,
see the HP StorageWorks Storage System Scripting Utility reference.
The following examples illustrate how to save and restore the storage system configuration data using
SSSU on a Windows host.
Example 1. Saving configuration data using SSSU on a Windows Host
1. Double-click on the SSSU desktop icon to run the application. When prompted, enter Manager
(management server name or IP address), User name, and Password.
2. Enter LS SYSTEM to display the EVA storage systems managed by the management server.
3. Enter SELECT SYSTEM system name,wheresystem name isthenameofthestoragesystem.
4. Enter CAPTURE CONFIGURATION pathname\filename,wherepathname identifies the location
where the configuration files will be saved, and filename isthenameusedastheprefixforthe
configurations files: for example, CAPTURE CONFIGURATION c:\EVAConfig\LargeEVA.
5. Enter EXIT to close the command window.
Example 2. Restoring configuration data using SSSU on a Windows Host
If it is necessary to restore the storage system configuration, it can be done using the following procedure:
1. Double-click on the SSSU desktop icon to run the application.
2. Enter FILE pathname\filename,wherepathname identifies the location where the configuration
files are be saved, and filename is the name of the first configuration file: for example, FILE
c:\EVAConfig\LargeEVA_Step1A.txt.
3. Repeat the preceding step for each configuration file.
Adding disk drives to the storage system
As your storage requirements grow, you may be adding disk drives to your storage system. Adding new
disk drives is the easiest way to increase the storage capacity of the storage system. Disk drives can be
added online without impacting storage system operation.
CAUTION:
When adding disks to an expansion cabinet on an EVA5000, do not install a disk in bays 12, 13, or 14
in enclosures 17, 20, or 24. These bays in enclosures 17, 20, and 24 do not receive a hard assigned
AL-PA. Installing a disk in any of these slots may impact the operation of the storage system.
Guidelines for adding disk drives
When adding new disk drives to the storage system, you should ensure that the disk drives are installed
in the correct positions to maintain availability. The disk drives should be distributed across the disk
enclosures to protect against the failure of a single disk enclosure.
Use the following guidelines when adding disk drives to your storage system:
•Install high performance and FATA disk drives in separate groups. These different drive types must
be in separate disk groups. You may also want to consider separating different drive capacities
and spindle speeds into different groups.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 39
•The disk drives should be distributed evenly across the disk enclosures. The number of disks of
a given type in each enclosure should not differ by more than one. For example, no enclosure
should have seven disks until all the other enclosures have at least six. A minimum of four disks
are required to be populated in every disk enclosure.
•Disk drives should be installed in vertical columns within the disk enclosures. Add drives vertically
in multiples of eight, completely filling columns if possible. Disk groups are more robust if filled
with the same number of disk drives in each enclosure. See Figure 6 for an example.
NOTE:
When adding multiple disk drives, add a disk and wait for its activity indicator (1) to stop flashing
(up to 90 seconds) before installing the next disk (see Figure 5). This procedure must be followed to
avoidunexpectedEVAsystembehavior.
Figure 5 Disk drive activity indicator
Creating disk groups
The new disks you add will typically be used to create new disk groups. Although you cannot select
which disks will be part of a disk group, you can control this by building the disk groups sequentially.
Add the disk drives required for the first disk group, and then create a disk group using these disk drives.
Now add the disk drives for the second disk group, and then create that disk group. This process gives
you control over which disk drives are included in each disk group. Figure 6 shows the sequential
building of vertical disk groups.
NOTE:
Standard and FATA disk drives must be in separate disk groups. Disk drives of different capacities and
spindle speeds can be included in the same disk group, but you may want to consider separating
them into separate disk groups.

Handling fiber optic cables
This section provides protection and cleaning methods for fiber optic connectors.
Contamination of the fiberopticconnectorsoneitheratransceiveroracableconnectorcanimpede
the transmission of data. Therefore, protecting the connector tips against contamination or damage
is imperative. The tips can be contaminated by touching them, by dust, or by debris. They can be
damaged when dropped. To protect the connectors against contamination or damage, use the dust
covers or dust caps provided by the manufacturer. These covers are removed during installation, and
are installed whenever the transceivers or cables are disconnected. Cleaning the connectors should
remove contamination.
The transceiver dust caps protect the transceivers from contamination. Donotdiscardthedustcovers.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 43
CAUTION:
To avoid damage to the connectors, always install the dust covers or dust caps whenever a transceiver
or a fiber cable is disconnected. Remove the dust covers or dust caps from transceivers or fiber cable
connectors only when they are connected. Do not discard the dust covers.
To minimize the risk of contamination or damage, do the following:
•Dust covers—Remove and set aside the dust covers and dust caps when installing an I/O module,
a transceiver or a cable. Install the dust covers when disconnecting a transceiver or cable.
•When to clean—If a connector may be contaminated, or if a connector has not been protected by
a dust cover for an extended period of time, clean it.
•How to clean:
1. Wipe the connector with a lint–free tissue soaked with 100% isopropyl alcohol.
2. Wipe the connector with a dry, lint–free tissue.
3. Dry the connector with moisture-free compressed air.
One of the many sources for cleaning equipment specifically designed for fiber optic connectors is:

I/O modules
Two I/O modules provide the interface between the drive enclosure and the host controllers. See
Figure 11. They route data to and from the disk drives using Loop A and Loop B, the dual-loop
configuration. For redundancy, only dual-controller, dual-loop operation is supported. Each controller is
connected to both I/O modules in the drive enclosure.

Fibre Optic Fibre Channel cables
The Enterprise Virtual Array uses orange, 50-µm, multi-mode, fiber optic cables for connection to the
SAN. The fiber optic cable assembly consists of two, 2–m fiber optic strands and small form-factor
connectors on each end. See Figure 13.
To ensure optimum operation, the fiber optic cable components require protection from contamination
and mechanical hazards. Failure to provide this protection can cause degraded operation. Observe the
following precautions when using fiber optic cables.
•To avoid breaking the fiber within the cable:
•Donotkinkth
ecable
• Do not use a cable bend-radius of less than 30 mm (1.18 in)
•To avoid deforming, or possibly breaking the fiber within the cable, do not place heavy objects
on the cable.
•To avoid contaminating the optical connectors:
• Do not touch the connectors
•Neverleave
the connectors exposed to the air
• Install a dust cover on each transceiver and fiber cable connector when they are disconnected
If an open connector is exposed to dust, or there is any doubt about the cleanliness of the connector,
clean the connector as described in Handling fiber optic cables.
CXO7972

Figure 13 Fibre Optic Fibre Channel cable
Copper Fibre Channel cables
The Enterprise Virtual Array Fibre Channel 10000-Series implementation uses copper Fibre Channel
cables to connect the drive enclosures to each other, or to the loop switches and to the HSV controllers.
The cables are available in 0.6–meter and 2.0–meter lengths. Copper cables provide performance
comparable to fiber optic cables. Copper cable connectors differ from fiber optic small form-factor
connectors (see Figure 14).
8164A-ST
Figure 14 Copper Fibre Channel cable
Fibre Channel disk drives
The Fibre Channel disk drives are hot-pluggable and include the following features:
•Dual-ported 2–Gbps Fibre Channel drive enclosure interface that allows up to 120 disk drives to
be supported per Fibre Channel drive enclosure pair.
•Compact, direct-connect design for maximum storage density and increased reliability and
signal integrity.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 49
•Both online high-performance disk drives and FATA disk drives in a variety of capacities and
spindle speeds.
•Better vibration damping for improved performance.
Up to 14 disk drives can be installed in a drive enclosure.
Disk drive status indicators
Three status indicators display the drive operational status. Figure 15 shows the disk drive status
indicators. Table 9 provides a description of each status indicator.

Power supplies
The two power supplies mount in the rear of the enclosure. See Figure 16. The supplies are autoranging
and operate on acountry-specificACinputvoltageof202to240VAC±10%,50to60Hz,±5%,(188
to264VAC,47to63Hz).
The DC outputs of this power supply are:
•+5.1 VDC for theEMU,I/Omodule,backplane, and disk drives
•+12.1 VDC for the disk drives
•+12.5 VDC for the disk drives
The output of each power supply is 499W, with a peak output of 681W. A single power supply can
support an enclosure with a full complement of disks.
The power supply circuitry provides protection against:
•Overloads
•Short circuits
•Overheating
Power supply status and diagnostic information is reported to the EMU with voltage, current, and
temperature signals.
See Regulatory Notices and Specifications for the enclosure power specifications.
The power supply temperature sensor provides a temperature range signal to the EMU, which uses this
signal to set the blower speed.
The power supply internal temperature can also control the speed of the blower. The higher the power
supply temperature, the faster the speed of the blower. If the power supply temperature exceeds a preset
value, the power supply automatically shuts down.
Blowers
The power supply–mounted blowers cool the enclosure by circulating air through the enclosure. The
blowers, under the control of the EMU or the associated power supply, can operate at multiple speeds.
This ensures that when the enclosure temperature changes the blowers can automatically adjust the
air flow.
If a blower is operating too slowly or has stopped (a “blower failure”), internal circuitry automatically
operates the remaining blower at a higher speed. Simultaneously, the error condition is reported in
several ways, including the power supply indicator, the audible alarm, the enclosure fault indicators,
and the EMU alphanumeric display.
Should both blowers fail, the power supplies automatically shut down.
NOTE:
The blowers are field-replaceable units and can be replaced, individually, while the system is running.
The blowers are also interchangeable. The failure of a power supply +12.5 VDC circuit disables
the associated blower.
The status indicator on the blower displays the status of both the power supply and the blower. See
Figure 16.SeeTable 12 for definitions of the indicator displays.

there is a blower problem, the other blower runs at a higher
speed. Recommended corrective actions:
•Check blower for proper operation. Replace if defective.
•Check power supplies for proper operation. Replace if
defective.
Drive enclosure EMU
The EMU provides increased protection against catastrophic failures. The EMU detects conditions such
as failed power supplies, failed blowers, elevated temperatures, and external air sense faults and
communicates these conditions to the storage system controllers.
The EMU for Fibre Channel-Arbitrated Loop (FC–AL) drive enclosures is fully compliant with SCSI-3
Enclosure Services (SES), and mounts in the left rear bay of a drive enclosure. See Figure 10.
Controls and displays

EMU functions
The primary functions of the EMU include:
•Using the Enclosure Services Processor (ESP) to control the Enclosure Services Interface (ESI) and
communicate with the controllers.
•Assigning the Enclosure Number (En), based upon the cabinet address bus feature.
•Displaying the bay 1 loop ID.
•Monitoring enclosure operation.
•Detecting, reporting, recording, and displaying conditions.
•Displaying EMU, enclosure, and element status.
•Implementing automatic corrective actions for some conditions.
•Providing enclosure status data to the controllers.
•Reporting the WWN and the logical address of all disk drives.
54 Enterprise Virtual Array hardware components
NOTE:
Although the EMU can determine the logical address of a drive, the EMU can neither display nor
change this information. HP Command View EVA can display the addresses from the EMU-supplied
status information.

Using the alphanumeric display
The two-character alphanumeric display is located at the top of the EMU (see Figure 17). This
seven-segment display provides information about multiple enclosure functions. The push buttons control
the data displayed or entered.
Alphanumeric display description
The top-level, two-character alphanumeric display (En, Li, rG, Au, and Er), is the display group. The
function of the other displays is display-group dependent. The default display is the enclosure number, a
decimal number in the range 00 through 14. The push buttons allow you to select the alphanumeric
display or to enter data.
•The bottom push button sequentially moves between groups and selects a display group .
See EMU display groups for a description of these display groups.
•The top push button moves between the levels within a display group (see 2, Figure 17).
Display groups
When you press and release the bottom push button, the alphanumeric display selects a different display
group. EMU display groups describes the display groups.
56 Enterprise Virtual Array hardware components
Table 16 EMU display groups
Display Display group Description
En Enclosure Number The enclosure number is the default display and is a decimal
number in the range 00 through 14. See Using the Enclosure
Number Featurefor detailed information.
Li Bay 1 Loop ID This display group has a single sublevel display that defines
the enclosure bay 1 loop ID. Valid loop IDs are in the range
00 through 7F.
rG Reporting Group This display group has two, two-digit displays that define the
reporting group number in the range 0000 through 4095.
Au Audible Alarm This display group provides control over the audible alarm or
horn. The sublevel displays are audible alarm enabled (on) or
audible alarm disabled (oF). See Audible Alarm Operations
for detailed information.
Fr Firmware Revision This display group defines the EMU code firmware version.
Er Error Condition This display group reads Er when there is an error condition.
NOTE:
Any time you press and release the bottom push button the display will change to En, Li, rG, Au, or Er.
Aflashing alphanumeric display indicates that you can edit an address, state, or view a condition report.
EMU push button status indicators
The push button status indicators display error conditions and the state of the audible alarm.
•When an error condition exists, the top push button status indicator is On.
• For a single error condition, the status indicator is On until the error condition is viewed.
• For multiple errors, the status indicator is On until the last error condition is viewed.
•The bottom push button indicator is On only when the alarm is muted or disabled.
Audible alarm operations
Whenever an error condition exists, the audible alarm automatically sounds until all errors are corrected.
You have the option of either muting or disabling the alarm.
•Disabling the audible alarm prevents it from sounding for any error condition.
•Muting the alarm silences it for the existing condition, but any new condition causes the alarm
to sound.
Audible alarm patterns
The audible alarm sound pattern differs depending on the type of error condition. See Table 17 for the
duration and the approximate relationship of these alarms. The most severe, active error condition
controls the alarm pattern.

Controlling the audible alarm
You can control the alarm with the push buttons. This process includes muting, enabling, and disabling.
When an error condition exists, the alphanumeric display reads Er, the alarm sounds, and you can:
•Correct all errors, thereby silencing the alarm until a new error occurs.
•Mute, or temporarily disable, the alarm by pressing and holding the bottom push button. The
alarm remains off until another error occurs, or until you enable (unmute) the alarm. When a new
error occurs, the alarm sounds and the push button indicator is off.
Using the mute feature ensures that you are aware of the more severe errors and provides you
with the capability of correcting them promptly.
•Disable the alarm to prevent any error condition from sounding the alarm.
NOTE:
Disabling the alarm does not prevent the EMU alphanumeric display from displaying Er. Nor does it
prevent HP Command View EVA from displaying the error condition report.
When the alarm is enabled (on), the bottom push button status indicator is off.
Enabling the audible alarm
To enable the alarm:
1. Press and release the bottom push button until the alphanumeric display is Au.
2. Press and hold the top push button until the alphanumeric display is a Flashing oF (Audible Alarm
Off).
NOTE:
When the alarm display is flashing, press and hold the top push button to cause the display
to toggle between On and oF. Press and release the top push button to cause the display to
select the next state.
3. Press and release the top push button to change the display to a flashing On (Audible Alarm On).
58 Enterprise Virtual Array hardware components
4. Press and release the bottom push button to accept the change and to display Au. The bottom push
button indicator is now off.
Muting or unmuting the audible alarm
You may want to mute the alarm in the following situations:
•The error does not require immediate corrective action.
•You cannot correct the error at this time. For example, the error may require a replacement part.
To mute the audible alarm:
NOTE:
Er isdisplayedinthealphanumericdisplaywhenanerrorconditionispresent.
1. Press and hold the bottom push button until the status indicator is On.
A muted alarm will remain off until a new condition report exists.
2. To unmute the alarm, press and hold the bottom push button until the status indicator is Off.Whena
new error condition occurs, the alarm will sound.
Disabling the audible alarm
CAUTION:
Disabling the audible alarm increases the potential of damage to equipment from a reported but
unobserved fault. HP does not recommend disabling the audible alarm.
Disabling the audible alarm affects only one enclosure. This action does not affect condition report
displays on the EMU alphanumeric display or errors reported by HP Command View EVA.
To disable the alarm:
1. Press and release the bottom push button until the alphanumeric display is Au.
2. Press and holdthetoppushbuttonuntilthealphanumericdisplayisaFlashingon (Audible Alarm
On).
NOTE:
When the alarm display is flashing, pressing and holding the top push button causes
the display to rapidly change between on and oF and also causes the display to select
the next state.
3. Press and release the top push button to change the display to a Flashing oF (Audible Alarm Off).
4. Press and release the bottom push button to accept the change and display Au. The bottom push
button indicator is now on.
NOTE:
Adisabledaudible alarm (the bottom push button indicator is on) cannot sound for
any error condition. To ensure that you are immediately alerted to error conditions, it is
recommended that the alarm mute function be used rather than the alarm disable function.
If you must use the disable function, remember to enable the audible alarm as soon as
possible to ensure that you are alerted to errors.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 59
Enclosure number feature
This section provides a description of the purpose, function, and operation of the EMU enclosure number
(En) feature.
En description
In a single rack configuration, the En is a decimal number in the range 00 through 14, which is
automatically assigned by the enclosure address bus.
NOTE:
Your storage system may use an enclosure address bus higher than 14 if your configuration includes an
optional expansion cabinet. The enclosure address bus connection determines the En. For a single rack,
the display is a decimal number in the range 01 th rough 14. For a multiple (t wo ) rack configuration, the
display is decimal number in the range 01 through 24.
By default, the two-character alphanumeric display shows this number. Pressing the bottom push button
changes the display to En,theEndisplaymode.
When the display is En, pressing and releasing the top push button displays the enclosure number.
A display of 00 indicates that the enclosure is not connected to the enclosure address bus. When this
condition exists, there is no EMU-to-EMU communication over the enclosure address bus.
A display of 01 through 14 indicates that the enclosure is connected to the enclosure address bus and can
exchange information with other enclosures on the enclosure address bus. The decimal number indicates
the physical position of the enclosure in relation to the bottom of the rack.
•01 is the address of the enclosure connected to the lower connector in the first (lower) enclosure
ID expansion cable.
•14 is the address of the enclosure closest to end of the bus, the upper connector in the last
(upper) ID expansion cable.
Unless there is an error condition, the display automatically returns to the enclosure number (01 through
14) one minute after a push button was last pressed.
Enclosure address bus
The enclosure address bus provides a means for managing and reporting environmental conditions within
the rack. It is composed of enclosure ID expansion cables that interconnect the drive enclosures and
controller enclosures. Two drive enclosures connect to each enclosure ID expansion cable.
The drive enclosure numbers are always assigned by the enclosure address bus. Connecting the EMU
CAB connector to an enclosure address bus enclosure ID expansion cable automatically establishes an
enclosure number of 01 through 14. Any drive enclosure not connected to the enclosure address bus
has the enclosure number 00.
NOTE:
The enclosure number is automatically assigned. You cannot manually assign an enclosure number.
The enclosures are numbered as shown in Figure 18.

numbering. Refer to the HP StorageWorks Enterprise Virtual Array hardware configuration guide for
more information.
For more information about the reporting group number, see ViewingtheReportingGroupFeature.
Enclosure address bus connections
Connecting the enclosures to the enclosure ID expansion cables establishes the enclosure address bus.
The enclosures are automatically numbered based on the enclosure ID expansion cable to which they are
connected. Figure 19 shows the typical configuration of a 42U cabinet with 14 enclosures.

Error Condition Reporting
The EMU constantly monitors enclosure operation and notifies you of conditions that could affect
operation. When an error condition is detected, the following action is taken:
•The EMU alphanumeric display is changed to Er. A condition report has precedence over all
other displays.
•The audible alarm sounds (if it is not disabled).
•The error is stored in the error queue.
•The error is passed to the controllers for processing and display by Command View EVA.
62 Enterprise Virtual Array hardware components
NOTE:
An error always generates a condition report. Not all condition reports are generated by errors.
Error condition categories
Each error condition is assigned to a category based on its impact on disk enclosure operation. The
following four error categories are used:
•Unrecoverable—themostsevereerrorcondition,itoccurswhenoneormoreenclosure
components have failed and have disabled some enclosure functions. The enclosure may be
incapable of correcting, or bypassing the failure, and requires repairs to correct the error.
NOTE:
To maintain data integrity, corrective action should be implemented immediately for an
UNRECOVERABLE condition.
•Critical—occurs when one or more enclosure components have failed or are operating outside
of their specifications. The failures impact the normal operation of some components in the
enclosure. Other components within the enclosure may be able to continue normal operations.
Prompt corrective action should be taken to prevent system degradation.
•Noncritical—occurs when one or more components inside the enclosure have failed or are
operating outside of their specifications. The failure of these components does not impact
continued normal operation of the enclosure. All components in the enclosure continue to
operate according to their specifications. The ability of the components to operate correctly
may be reduced should other errors occur. Prompt corrective action should be taken to prevent
system degradation.
•Information—the least severe condition indicates a condition exists that does not reduce the
capability of a component. However, the condition can become an error and require corrective
action. An INFORMATION condition provides an early warning, which enables you to prepare
to implement corrective action before a component fails. Correction of the reported problem
may be delayed.
The error conditions are prioritized by severity—from most severe to least. The most severe condition
takes precedence and is reported first when multiple errors are detected. The reporting characteristics
for each error condition are listed in Table 18.
Table 18 Error condition reporting characteristics
Error condition Takes precedence over Audible alarm pattern1
UNRECOVERABLE All other conditions On continuously
CRITICAL NONCRITICAL and
INFORMATION Sounds three times per alarm cycle
NONCRITICAL INFORMATION Sounds two times per alarm cycle
INFORMATION No other conditions Sounds once per alarm cycle
1The pattern occurs when the condition is the most severe active condition
Error queue
The EMU maintains an internal error queue for storing error conditions. Each error condition remains in
the error queue until the problem is corrected, or for at least 15 seconds after the error is reported. This
ensures that when there are multiple errors or a recurring error, each can be displayed. Each entry in the
error queue can be displayed using a combination of the top and bottom buttons. Each error entry in the
queue contains the element type, the element number, and the error code.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 63
Correcting the error removes the associated condition from the error queue. Replacing the EMU will
also clear the error conditions. The order in which the EMU displays the error queue information is
based on two factors:
•The severity of the error
•Thetimetheerroroccurred
Themostsevereerrorinthequeuealwayshasprecedence,regardlessofhowlonglesssevereerrorshave
been in the queue. This ensures that the most severe errors are displayed immediately.
NOTE:
Whenviewinganerror,theoccurrenceofamoresevereerrortakesprecedenceandthedisplaychanges
to the most severe error.
The earliest reported condition within an error type has precedence over errors reported later. For
example, if errors at all levels have occurred, the EMU displays them in the following order:
1. UNRECOVERABLE errors in the sequence they occurred.
2. CRITICAL errors in the sequence they occurred.
3. NONCRITICAL errors in the sequence they occurred.
4. INFORMATION conditions in the sequence they occurred.
Error condition report format
Each EMU detected condition generates a condition report containing three pieces of information.
•Element type The first two-digit hexadecimal display defines the element type reporting the
problem. The format for this display is e.t. with a period after each character. Valid element
types are 0.1. through F.F.
•Element number The second display is a two-digit decimal number that defines the specificelement
reporting the problem. The format for this display is en. with a period after the second character.
•Error code The third display is a two-digit decimal number that defines the specificerrorcode.
The format for this display is ec without any periods.
For detailed information about each condition report, including recommended corrective actions.
Navigating the error condition display
When an error condition occurs, the alphanumeric display changes to Er and the error menu is active.
Thebuttonsareusedtodisplaytheerrorconditionvalues.
Perform the following procedure to display error conditions. Figure 20 illustrates the sequence for
displaying error conditions.
1. With Er in the display, press and hold the top push button until the first element type is displayed.

Analyzing condition reports
Analyzing each error condition report involves three steps:
1. Identifying the element.
2. Determining the major problem.
3. Defining additional problem information.
Reporting group feature
Another function of the enclosure address bus is to provide communications within a reporting group.
A Reporting Group (rG) is an HSV controller pair and the associated drive enclosures. The controller
pair automatically assigns a unique (decimal) four-digit Reporting Group Number (RGN) to each EMU
on a Fibre Channel drive enclosure.
Each of the drive enclosures on a loop pair are in one reporting group:
•All of the drive enclosures on loop pair 1, both loop 1A and loop 1B, share a unique reporting
group number.
•All of the drive enclosures on loop pair 2, both loop 2A and loop 2B, share a unique reporting
group number.
Each EMU collects environmental information from the associated enclosure and broadcasts the
information to reporting group members using the enclosure address bus. Information from enclosures
in other reporting groups is ignored.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 65
Reporting group numbers
The reporting group number (RGN) range is 0000 through 4099, decimal.
•0000 is reserved for enclosures that are not part of any reporting group.
•0001 through 0015 are RGNs reserved for use by the EMU.
•0016 through 4095 are valid RGNs.
•4096 through 4099 are invalid RGNs.
The reporting group numbers are displayed on the EMU alphanumeric display as a pair of two-digit
displays. These two displays are identified as rH and rL.
•Valid rH displays are in the range 00 through 40, and represent the high-order (most significant)
two digits of the RGN.
•Valid rL displays are in the range 00 through 99, and represent the low-order (least significant)
two digits of the RGN.
To view a reporting group number:
1. Press and release the bottom push button until the alphanumeric display is rG.
2. To display the two most significant digits of the Reporting Group Number, press and hold the
top push button unit the display is rH.
3. Press and release the top push button to display the first two digits of the RGN.
4. Press and release the top push button until the alphanumeric display is rH.
5. Press and hold the top push button until the alphanumeric display is rL.
6. Press and release the top push button to display the last two digits of the Reporting Group Number.
7. To exit the display, press and release the bottom push button until the alphanumeric display is rG.
Fibre Channel loop switches
The Fibre Channel loop switch acts as a central point of interconnection and establishes a fault-tolerant
physical loop topology between the controllers and the disk enclosures.

Power-on self test (POST)
When you power on the Fibre Channel switch, it performs a Power–on Self Test (POST) to verify that the
switch is functioning properly. During a POST, all of the indicators turn on for approximately two seconds.
Then, turn off all of the indicators, except the power indicator.
If the Port Bypass indicators are blinking at a constant rate and the POST Fault indicator is on, the
switch detected a fault during the POST. In this case, you need to contact your HP authorized service
representative.
Reading the switch indicators
The Fibre Channel switch contains both system indicators and port indicators. The system indicators
indicate the status of the switch, and the port indicators provide status of a specificport.Figure 21 shows
the Fibre Channel switch with the system and port indicators.
Table 19 lists and describes the system indicators.

Off Off Indicates that the port does not have an SFP installed and is
bypassed by the loop.
On Off Indicates that the port is operating normally. The port and device
are fully operational.
On On Indicates the that port is in a bypassed state. The port is
non-operational due to loss of signal, poor signal integrity, or
the Loop Initialization Procedure (LIP).Note: This condition is
also normal when the SFP is present but not attached to a Fibre
Channel drive enclosure node or when the SFP is present and
attached to only a cable assembly. Attaching the SFP to a device
and plugging it into the port should initiate the LIP by the attached
device.
Off On Indicates a Tx fault. The port is non-operational due to an SFP
transmitter fault, improperly-seated SFP, or another failed device.

High availability features
Two interconnected controllers ensure that the failure of a controller component does not disable the
system. A single controller can fully support an entire system until the defective controller, or controller
component, is repaired. For EVA5000 configurations, the complete data redundancy configuration
includes two Loop A and two Loop B data paths. For EVA3000 configurations, data redundancy is
accomplished with two Loop A data paths.
Each controller has two lead-acid cache batteries that provide power to the cache memory. When the
batteries are fully charged, they can provide power to the cache for up to 96 hours.
Operator control panel
The operator control panel (OCP) provides a direct interface to each controller. From the OCP you
can display storage system status and configuration information, shut down the storage system, and
manage the password.
The OCP includes a 40-character LCD alphanumeric display, four push buttons, and four status indicators
See Figure 23.
HP Command View EVA is the tool you will typically use to display storage system status and configuration
information or perform the tasks available from the OCP. However, if HP Command View EVA is not
available, the OCP can be used to perform these tasks.

shutdown methods are explained in Table 26.
•Shutting down the controller (see Shutting the controller down).
•Restarting the system (see Restarting the System).
•Uninitializing the system (see Uninitializing the System).
To ensure that you do not mistakenly activate a shutdown procedure, the default state is always NO,
indicating do not implement this procedure. As a safeguard, implementing any shutdown method
requires you to complete at least two actions.
Table 26 Shutdown methods
LCD prompt Description
Restart System? Implementing this procedure establishes communications between the storage
system and HP Command View EVA. This procedure is used to restore
the controller to an operational state where it can communicate with HP
Command View EVA.
Power off system? Implementing this procedure initiates the sequential removal of controller
power. This ensures no data is lost. The reasons for implementing this
procedure include replacing a drive enclosure.
Uninitialize? Implementing this procedure will cause the loss of all data. For a detailed
discussion of this procedure, see Uninitializing the System.
Shutting the controller down
Use the following procedure to access the Shutdown System display and execute a shutdown procedure.
NOTE:
HP Command View EVA is the preferred method for shutting down the controller. Shut down the
controller from the OCP only if HP Command View EVA cannot communicate with the controller.
Shutting down the controller from the OCP removes power from the controller on which the procedure is
performedonly. Torestorepower,togglethecontroller’spowerswitch.

Power supply/blower assembly
Two power supply/blower assemblies provide the necessary operating voltages and cooling to all
controller enclosure components. If one power supply/blower assembly fails, the remaining is capable
of operating the enclosure.
Each power supply/blower includes an amber status indicator which will be on if either of the fallowing
conditions occur:
•The blower is operating at a slow speed or has failed and requires replacement.
•The power supply has failed and requires replacement.
76 Enterprise Virtual Array hardware components
Cache battery
Two cache batteries provide backup power to maintain the contents of the controller cache when AC
power is lost and the storage system has not been shutdown properly. When fully charged the batteries
can sustain the cache contents for to 96 hours. The batteries are located behind the OCP.
Each battery includes an amber status indicator which will be on if the battery fails. If the status indicator
is on, the battery should be replaced as soon as possible.
HSV controller cabling
All data cables and power cables attach to the rear of the controller. Adjacent to each data connector is
a two-colored link status indicator. Table 23 identifies the status conditions presented by these indicators.
NOTE:
These indicators do not indicate whether there is communication on the link, only whether the link
can transmit and receive data.
The data connections are the interfaces to the disk drive enclosures or loop switches (depending on your
configuration), the other controller, and the fabric. Fiber optic cables link the controllers to the fabric,
and, if an expansion cabinet is part of the configuration, link the expansion cabinet drive enclosures to
the loop switches in the main cabinet. Copper cables are used between the controllers (mirror port) and
between the controllers and the drive enclosures or loop switches.
Racks
All storage system components are mounted in a rack. Each configuration includes two controller
enclosures (the controller pair), drive enclosures, FC loop switches (if required), and an expansion
bulkhead. Each controller pair and all the associated drive enclosures form a single storage system.
Rack configurations
Each system configuration depends on the number of disk enclosures included in the storage system. For
more information about racks and configurations, including expansion and interconnection, refer to the
HP StorageWorks Enterprise Virtual Array hardware configuration guide.
Power distribution
AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted at the
bottom rear of the rack. The characteristics of the fully-redundant rack power configuration are as follows:
•Each PDU is connected to a separate circuit breaker-protected, 30–A AC site power source
(220–240 VAC ±10%, 50 or 60–Hz, ±5%). Figure 24 illustratesthecompatible60–Hzand
50–Hz wall receptacles.

IEC 309 receptacle, 3–wire, 30–A, 50–Hz
Figure 24 60–Hz and 50–Hz wall receptacles
•The standard power configuration for any Enterprise Virtual Array rack is the fully redundant
configuration. Implementing this configuration requires:
• Two separate circuit breaker-protected, 30–A site power sources with a compatible wall
receptacle (see Figure 24).
• One dual PDU assembly. Each PDU connects to a different wall receptacle.
• Six Power Distribution Modules (PDM) per rack. Three PDMs mount vertically on each side
of the rack. Each set of PDMs connects to a different PDU.
• The drive enclosure power supplies on the left (PS 1) connect to the PDMs on the left with a
gray, 66 cm (26 in) power cord.
• The drive enclosure power supplies on the right (PS 2) connect to the PDMs on the right with a
black, 66 cm (26 in) power cord.
• The upper controller connects to a PDM on the left with a gray, 152 cm (60 in) power cord.
• The lower controller connects to a PDM on the right with a black, 66 cm (26 in) power cord.
NOTE:
Drive enclosures, when purchased separately, include one 50 cm black cable and one 50 cm gray cable.
The configuration provides complete power redundancy and eliminates all single points of failure for
both the AC and DC power distribution.
PDUs
Each Enterprise Virtual Array rack has either a 50– or 60–Hz, dual PDU mounted at the bottom rear
of the rack. The 228481–002/228481–003 PDU placement is back-to-back, plugs facing down, with
switches on top.
•The standard 50–Hz PDU cable has an IEC 309, 3–wire, 30–A, 50–Hz connector.
•The standard 60–Hz PDU cable has a NEMA L6–30P, 3–wire, 30–A, 60–Hz connector.
If these connectors are not compatible with the site power distribution, you must replace the PDU power
cord cable connector.
Each of the two PDU power cables has an AC power source specific connector. The circuit
breaker-controlled PDU outputs are routed to a group of four AC receptacles (see Figure 25). The voltages
are then routed to PDMs, sometimes referred to as AC power strips, mounted on the two vertical rails
in the rear of the rack.

Rack AC power distribution
The power distribution in an Enterprise Virtual Array rack is the same for all variants. The site AC input
voltage is routed to the dual PDU assembly mounted in the rack lower rear. Each PDU distributes AC to a
maximum of four PDMs mounted on the left and right vertical rails (see Figure 27).
•PDMs 1 through 3 connect to receptacles A through D on PDU 1. Power cords connect these
PDMs to the number 1 drive enclosure power supplies and to the upper controller enclosure.

Rack System/E power distribution components
AC power is distributed to the Rack System/E rack through Power Distribution Units (PDU) mounted on the
two vertical rails in the rear of the rack. Up to four PDUs can be mounted in the rack—two mounted
ontherightsideofthecabinetandtwomountedontheleftside.
Each of the PDU power cables has an AC power source specific connector. The circuit breaker-controlled
PDU outputs are routed to a group of ten AC receptacles. The storage system components plug directly
into the PDUs.
Rack AC power distribution
The power distribution configuration in a Rack System/E rack depends on the number of storage systems
installed in the rack. If one storage system is installed, only two PDUs are required. If multiple storage
systems are installed, four PDUs are required.
The site AC input voltage is routed to each PDU mounted in the rack. Each PDU distributes AC through
ten receptacles directly to the storage system components.
•PDUs 1 and 3 (optional) are mounted on the left side of the cabinet. Power cords connect these
PDUs to the number 1 drive enclosure power supplies and to the controller enclosures.
•PDUs 2 and 4 (optional) are mounted on the right side of the cabinet. Power cords connect these
PDUs to the number 2 drive enclosure power supplies and to the controller enclosures.

Moving and stabilizing a rack
WARNING!
The physical size and weight of the rack requires a minimum of two people to move. If one person tries
to move the rack, injury may occur.
To ensure stability of the rack, always push on the lower half of the rack. Be especially careful when
moving the rack over any bump (e.g., door sills, ramp edges, carpet edges, or elevator openings). When
the rack is moved over a bump, there is a potential for it to tip over.
Moving the rack requires a clear, uncarpeted pathway that is at least 80 cm (31.5 in) wide for the
60.3 cm (23.7 in) wide, 42U rack. A vertical clearance of 203.2 cm (80 in) should ensure sufficient
clearance for the 200 cm (78.7 in) high, 42U rack.
CAUTION:
Ensurethatnoverticalorhorizontalrestrictionsexistthatwouldpreventrackmovementwithout
damaging the rack.
Make sure that all four leveler feet are in the fully raised position. This process will ensure that the casters
support the rack weight and the feet do no impede movement.
Each rack requires an area 600 mm (23.62 in) wide and 1000 mm (39.37 in) deep (see Figure 28).

This chapter describes the procedures for replacing CRUs. Information about initial enclosure installation,
ESD protection, and common replacement procedures is also presented.
Customer self repair (CSR)
Table 27 identifies which hardware components are customer replaceable. Using WEBES, ISEE or other
diagnostic tools, a support specialist will work with you to diagnose and assess whether a replacement
component is required to address a system problem. The specialist will also help you determine whether
you can perform the replacement.
Partsonlywarrantyservice
Your HP Limited Warranty may include a parts only warranty service. Under the terms of parts only
warranty service, HP will provide replacement parts free of charge.
For parts only warranty service, CSR part replacement is mandatory. If you request HP to replace these
parts, you will be charged for the travel and labor costs of this service.
Best practices for replacing hardware components
The following information will help you replace the hardware components on your storage system
successfully. Follow these tips any time you must replace a component.
CAUTION:
Removing a component significantly changes the air flow within the enclosure. All components must be
installed for the enclosure to cool properly. If a component fails, leave it in place in the enclosure until a
new component is available to install.
Verifying component failure
•Consult HP technical support to verify that the hardware component has failed and that you
are authorized to replace it yourself.
•Additional hardware failures can complicate component replacement. Check HP StorageWorks
Command View EVA and/or the WEBES System Event Analyzer as follows to detect any
additional hardware problems:
• When you have confirmed that a component replacement is required, you may want to clear
the Real Time Monitoring view. This makes it easier to identify additional hardware problems
that may occur while waiting for the replacement part.
• Before installing the replacement part, check the Real Time Monitoring view for any new
hardware problems. If additional hardware problems have occurred, contact HP support
before replacing the component.
• See the System Event Analyzer online help for additional information.
Procuring the spare part

Replacing the failed component
CAUTION:
Components can be damaged by electrostatic discharge. Observe the following proper anti-static
protection:
•Always transport and store CRUs in an ESD protective enclosure.
•Do not remove theCRUfromtheESDprotectiveenclosureuntilyouarereadytoinstallit.
•Always use ESD precautions, such as a wrist strap, heel straps on conductive flooring, and an ESD
protective smock when handling ESD sensitive equipment.
•Avoid touching the CRU connector pins, leads, or circuitry.
•Do not place ESD generating material such as paper or non anti-static (pink) plastic in an ESD
protective enclosure with ESD sensitive equipment.
•HP recommends waiting until periods of low storage system activity to replace a component.
•When replacing components at the rear of the rack, cabling may obstruct access to the
component. Carefully move any cables out of the way to avoid loosening any connections. In
particular, avoid cable damage that may be caused by:
• Kinking or bending.
• Disconnecting cables without capping. If uncapped, cable performance may be impaired by
contact with dust, metal or other surfaces.
• Placing removed cables on the floororothersurfaces,wheretheymaybewalkedonor
otherwise compressed.
•Replacement procedures are provided with each component. You can also download the
replacement instructions from the Manuals page of the Business Support Center website. see
“Related documentation” on page 13 for more information.
Returning the defective part
HP specifies, in the materials shipped with a replacement CSR part, whether the defective component
must be returned to HP. Where required, you must ship the defective component back to HP within a
defined period of time, normally five (5) business days. The defective component must be returned with
the associated documentation provided in the shipping material. Failure to return the defective component
may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and
component return costs and determine the courier/carrier to be used.
Before you begin
Observe the following precautions when replacing the disk:
•Ensure you have a replacement part available before removing the failed component. Removing
a component impacts cooling within the enclosure.
•Donotremovemorethanonediskatatimefromtheenclosure.Doingsowillimpactcoolingof
the enclosure and may cause data loss.
•Parts can be damaged by electrostatic discharge. Use proper anti-static protection.
•Have a copy of the product user guide available for reference. You can download a copy of the
user guide from the product support page on the HP website.

Types of disk failures
There are two types of disk failures:
•Hard failure:T
he disk is no longer functioning properly and has been assigned a failed status.
This type of failure is indicated by an operational state of Failed in HP Command View EVA.
The amber fault status indicator on the disk is typically on.
•Impending failure: Although the disk is still functioning, errors have been detected that indicate
an impending failure. This type of failure is not accompanied by a failed status.
CAUTION:
A disk with an impending failure will appear to be operating normally in HP Command View
EVA, and the fault light on the disk will not be on. Therefore, it is important that you positively
identify the disk before performing the replacement. Work with the HP Solution Center to ensure
you identify the correct disk for replacement.
Checking system redundancy
Before replacing a disk, check the redundancy status of the entire storage system to ensure a disk can
be removed without impacting data availability.
CAUTION:
Do not proceed with the disk replacement until you are certain the storage system is redundant.
1. Open HP Command View EVA and click the icon of the storage system you want to check (Figure 32).
2. On the Initialized Storage System Properties window, click Check Redundancy (Figure 33).
3. If the system is redundant, continue with Verifying component failure.
If the system is not redundant, information is displayed indicating the cause of the lack of redundancy.
See the HP Command View EVA online help to interpret the information that is displayed. In this
situation, work with your HP call center agent to determine how to proceed.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 89
Figure 32 Selecting a storage system
Figure 33 Checking redundancy
Verifying component failure
Before replacing a disk, use the following methods to verify component failure:
CAUTION:
If HP Command View EVA does not present a status consistent with the disk status indicators, or if HP
Command View EVA or your system monitoring tool indicates multiple hardware failures, contact HP
support for assistance (http://www.hp.com/support).
•Analyze any failure messages received. Error messages identify each disk by its rack, enclosure,
bay, and UUID (World Wide Name). Record this information to assist you in identifying the
correct disk before replacing it.
The following is a sample of the disk identification information:

Virtual Array family.
Regulatory notices
Federal Communications Commission (FCC) notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic
devices, including computers, generate RF energy incidental to their intended function and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into two classes, A
and B, depending upon their intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment. Class B devices are those that may
reasonably be expected to be installed in a residential environment (for example, personal computers).
The FCC requires devices in both classes to bear a label indicating the interference potential of the device
as well as additional operating instructions for the user.
The rating label on the device shows the classification (A or B) of the equipment. Class B devices have an
FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label.
After the class of the device is determined, refer to the corresponding statement in the following sections.

B EMU-generated condition reports
This section provides a description of the EMU generated condition reports that contain the following
information:
•Element type (et), a hexadecimal number in the range 01 through FF.
•Element number (en), a decimal number in the range 00 through 99 that defines a specific
problem.
•Error code (ec), a decimal number in the range 00 through 99.
•The recommended corrective action.
NOTE:
The conventions used to differentiate between the elements of the condition report are:
• Element type—period after each character
• Element number—period after the second character
• Error code—no periods
The EMU can send error messages to the controller for transmission to HP Command View EVA. The
messages displayed are specific to HP Command View EVA and are not within the scope of this
publication.
The I/O modules have the built-in intelligence to:
•Observe fibre channel events
•Bypass drive ports based on events
•Perform drive port testing and monitoring to prevent poor-performing drives from participating
in the loop
•Communicate fibre channel events to the controllers
This appendix explains the condition report format, correcting problems, and how to identify element
types. The error codes are arranged in element type sequence (that is, 0.1., 0.2., 0.3., etc.).
Condition report format
When the EMU alphanumeric display is Er, three additional displays identify the possible cause of the
problem: the element type, the specificelement,andtheerrorcode,whichdefines the possible cause
of the problem.
•The first-level display identifies the type of element affected with two alphanumeric characters
separated by periods such as 0.1., 0.2., 1.3., F.F., and so forth. A disk drive problem would
display an element type number of 0.1.
•The second-level display identifies the element affected with a two-digit, decimal number followed
by a period. For example, when a bay 6 drive error occurs, the element number display is 06.; a
display of 14 . indicates a bay 14 p r o b l e m.
•The third-level display identifies a specific problem, the error code with a two-digit, decimal
number. For example, should the problem be either the installation of an incorrectly configured
drive or one that cannot operate at the loop link rate, the display is 01.
HP StorageWorks 3000/5000 Enterprise Virtual Array user guide (VCS 4.xxx) 119
Correcting errors
Correcting an error may require you to perform a specific set of actions. In some cases, the only available
corrective action is to replace the element.
Table 49 lists the element type codes assigned to the drive enclosure elements.

1Does not generate a condition report. However, for any error, you should record the error code. Then, implement the
recommended corrective action.
Drive conditions
The format of a disk drive condition report is 0.1.en.ec,where:
•0.1. is the disk drive element type number
•en. is the two-character disk drive element
•ec is the error code
A direct correlation exists between the disk drive element number and the bay number. However, no
direct correlation exists between the disk drive bay number and the device Fibre Channel drive enclosure
physical address. The Fibre Channel drive enclosure physical address is assigned by negotiation
during system initialization.
The following sections define the disk drive error codes.
0.1.en.01CRITICALcondition—Driveconfiguration or drive link rate
As each drive spins up and comes on-line, the EMU determines if the drive is Fibre Channel compatible
and can operate at the link rate (1 Gbps or 2 Gbps) established by the I/O module. If either of these
conditions are not met, the EMU issues the condition report 0.1.en.01.
The corrective actions for these conditions are:
•When the drive is not Fibre Channel-compatible you must install a Fibre Channel compatible
driveoradriveblank.
120 EMU-generated condition reports
•When the drive is Fibre Channel-compatible, the EMU compares the drive link rate with the I/O
module link rate, the loop link rate.
If the EMU cannot determine the drive link rate, the EMU activates the drive bypass function for one

C Controller fault management
This appendix describes how the controller displays events and termination event information. Termination
event information is displayed on the LCD. HP Command View EVA enables you to view controller events.
This appendix also discusses how to identify and correct problems.
Once you create a storage system, an error condition message has priority over other controller displays.
HP Command View EVA provides detailed descriptions of the storage system error conditions, or faults.
The Fault Management displays provide similar information on the LCD, but not in as much detail.
Whenever possible, refer to HP Command View EVA for fault information.
Using HP Command View EVA
HP Command View EVA provides detailed information about each event affecting system operation in
either a Termination Event display or an Event display. These displays are similar, but not identical.
GUI termination event display
A problem that generates the Termination Event display prevents the system from performing a specific
function or process. You can use the information in this display (see GUI Termination Event Display)
to diagnose and correct the problem.
NOTE:
The major differences between the Termination Event display and the Event display are:
• The Termination Event display includes a Code Flag field; it does not include the EIP Type field.
• The Event display includes an EIP type field; it does not include a Code Flag field.

Fault management displays
When you do not have access to the GUI, you can display and analyze termination codes (TCs) on the
OCP LCD display. You can then use the event text code document, as described in the section titled
“Interpreting Fault Management Information” to determine and implement corrective action. You can
also provide this information to the authorized service representative should you require additional
support. This lets the service representative identify the tools and components required to correct the
conditionintheshortestpossibletime.
When the fault management display is active, you can either display the last fault or display detailed
information about the last 32 faults reported.
Displaying Last Fault Information
Complete the following procedure to display Last Fault information
1. When the Fault Management display is active, press to select the Last Fault menu.
2. Press to display the last fault information.
The first line of the TC display contains the eight-character TC error code and the two-character IDX

expressed as “U” spacing or panel heights. Repeating hole patterns are spaced
every 1.75 inches (44.45 mm) and based on EIA’s Standard RS310C.For
example, a 3U unit is 5.25inches (133.35 mm) high, and a 4U unit is 7.0inches
(177.79 mm) high.
read caching A cache method used to decrease subsystem response times to a read request
by allowing the controller to satisfy the request from the cache memory rather
than from the disk drives. Reading data from cache memory is faster than
reading data from a disk. The read cache is specified as either On or Off for
each virtual disk. The default state is on.
154 Glossary
read ahead
caching A cache management method used to decrease the subsystem response time to
a read request by allowing the controller to satisfy the request from the cache
memory rather than from the disk drives.
reconstruction The process of regenerating the contents of a failed member data. The
reconstruction process writes the data to a spare set disk and incorporates the
spare set disk into the mirrorset, striped mirrorset or RAID set from which the
failed member came.
redundancy 1. ElementRedundancy—Thedegreetowhichlogicalorphysicalelements
are protected by having another element that can take over in case of
failure. For example, each loop of a device-side loop pair normally works
independently but can take over for the other in case of failure.
2. Data Redundancy—The level to which user data is protected. Redundancy
is directly proportional to cost in terms of storage usage; the greater the
levelofdataprotection,themorestoragespaceisrequired.
redundant power
configuration A capability of the Enterprise storage system racks and enclosures to allow
continuous system operation by preventing single points of power failure.
•For a rack, two AC power sources and two power conditioning units
distribute primary and redundant AC power to enclosure power supplies.
•For a controller or drive enclosure, two power supplies ensure that the DC
power is available even when there is a failure of one supply, one AC
source, or one power conditioning unit. Implementing the redundant power
configuration provides protection against the loss or corruption of data.
reporting group An Enterprise Storage System controller pair and the associated disk drive
enclosures. The Enterprise Storage System controller assigns a unique decimal
reporting group number to each EMU on its loops. Each EMU collects disk
drive environmental information from its own sub-enclosure and broadcasts the
data over the enclosure address bus to all members of the reporting group.
Information from enclosures in other reporting groups is ignored.

Snapclone A virtual disk that can be manipulated while the data is being copied. Only an
Active member of a virtual disk family can be snapcloned.
The Snapclone, like a snapshot, reflects the contents of the source virtual disk at
a particular point in time. Unlike the snapshot, the Snapclone is an actual clone
of the source virtual disk and immediately becomes an independent Active
member of its own virtual disk family.
snapshot A temporary virtual disk (Vdisk) that reflects the contents of another virtual disk
at a particular point in time. A snapshot operation is only done on an active
virtual disk. Up to seven snapshots of an active virtual disk can exist at any
point. The active disk and its snapshot constitute a virtual family.

UPS Uninterruptible Power Supply. A battery-operated power supply guaranteed to
provide power to an electrical device in the event of an unexpected interruption
to the primary power supply. Uninterruptible power supplies are usually rated
by the amount of voltage supplied and the length of time the voltage is supplied.
Vdisk Virtual Disk. A simulated disk drive created by the controllers as storage
for one or more hosts. The virtual disk characteristics, chosen by the storage
administrator, provide a specific combination of capacity, availability,
performance, and accessibility. A controller pair simulates the characteristics
of the virtual disk by deploying the disk group from which the virtual disk was
created.
The host computer sees the virtual disk as “real,” with the characteristics of an
identical physical disk.

Vraid0 A virtualization technique that provides no data protection. Data host is broken
down into chunks and distributed on the disks comprising the disk group from
which the virtual disk was created. Reading and writing to a Vraid0 virtual disk
is very fast and makes the fullest use of the available storage, but there is no
data protection (redundancy) unless there is parity.
Vraid1 A virtualization technique that provides the highest level of data protection.
All data blocks are mirrored or written twice on separate physical disks. For
read requests, the block can be read from either disk, which can increase
performance. Mirroring takes the most storage space because twice the storage
capacity must be allocated for a given amount of data.
Vraid5 A virtualization technique that uses parity striping to provide moderate data
protection. Parity is a data protection mechanism for a striped virtual disk. A
striped virtual disk is one where the data to and from the host is broken down
into chunks and distributed on the physical disks comprising the disk group in
which the virtual disk was created. If the striped virtual disk has parity, another
chunk (a parity chunk) is calculated from the set of data chunks and written to
the physical disks. If one of the data chunks becomes corrupted, the data can
be reconstructed from the parity chunk and the remaining data chunks.
