Product Description

General Description
Hewlett-Packard’s StorageWorks Disk System 2300 (referred to in this guide as
the disk system) is a high-availability Ultra160 SCSI storage product. Dual SCSI
ports on dual bus controllers provide LVD connections to the host. Fourteen slots
accept high-speed, high-capacity LVD SCSI disks connected to an LVD
midplane. Maximum data throughput is 160 Mbytes/sec. Thirteen disk systems
fill a 2-meter System/E rack. Filled with 18-Gbyte disks, the 2-meter Rack
System/E yields 3.3 Terabytes of storage; with 36-Gbyte disks, 6.6 Terabytes of
storage and with 73-Gbyte disks, 13.3 Terabytes.
Modular and redundant components are easy to upgrade and maintain. Disks,
power supply/fan modules, and bus control cards (BCCs) are replaceable parts
that plug into individual slots in the front and back of the disk system. Redundant
power supply/fan modules, and BCCs can be removed and replaced without
interrupting storage operations. Disks also can be replaced with the system on
and with only the affected file systems taken off-line. Hewlett-Packard technical
support is optional for these procedures.
Special electronics and HP-UX software enable remote monitoring and
diagnostics. Sensors on the BCCs monitor the disk system environment,
including temperature, voltage, fan speed, and component status. HewlettPackard’s Command View SDM reports any changes in environmental status to
user-defined locations. Standard HP-UX diagnostic utilities also report
environmental data for enhanced troubleshooting.

Product Description

Product Description

Features

Product Description

Status Indicators
LEDs on the disk system enable you to detect and replace failed components and
so prevent or minimize users’ downtime. For additional information about LEDs,
see Chapter 4, Troubleshooting.
On the front of the disk system, a pair of LEDs indicates the status of the disk
system, and an LED for each slot shows disk I/O activity:
■ The system power LED (B in Figure 1) indicates that power is on or off.
■ The system fault LED (C in Figure 1) indicates whether or not a fault has

occurred anywhere in the disk system.
■ At the bottom of each disk module, the left LED (F in Figure 1) indicates the

presence of I/O activity on the disk.
■ The second LED on each disk module (E in Figure 1) can be flashed to help a

customer engineer (CE) locate the disk for physical inspection or removal.
■ The second LED is also used as a fault indicator for that specific disk module.

LEDs (I and K in Figure 2) on the back of the disk system indicate the status of
replaceable components and the SCSI bus: See Chapter 4, Troubleshooting, for
specific LED information.

Product Description

Power/Standby Switch
Located at the upper right corner of the front of the disk system, the power switch
(D in Figure 1) interrupts DC power from the power supplies to the BCCs and
other internal components. Input AC power to the power supplies is controlled by
the power cords and the AC source.

High Availability
High availability is a general term describing computer systems that are designed
to minimize planned and unplanned downtime. The disk system supports current
systems’ high availability requirements through the following features:
■ Hot-pluggable, high-capacity, high-speed disks
■ Redundant, hot-pluggable, user-replaceable power supplies and BCCs
■ Online firmware upgrades
■ Hardware event monitoring and real-time error reporting

Clustering (NT)
The HP Disk System 2300 is Microsoft® Cluster certified for a variety of
solutions. For specific information about supported configurations, see the
Hewlett-Packard Company or Microsoft web pages:
http://hp.com
http://microsoft.com

Upgradability
You can increase disk system storage capacity by:
■ Replacing disk drives with higher-capacity disk drives
■ Adding disks in unused slots

None of these actions require shutting down the product, but some may require
the use of system utilities to manage file systems.
Upgrade BCC and disk firmware using an on-line download function. See
Chapter 3, Updating Firmware.

Product Description

Environmental Services
Product Description

Environmental services circuitry monitors the following elements:
■ Fan rotation
■ Power supply output
■ Power supply status (fan status)
■ Disk drive status, presence
■ BCC status
■ Temperature
■ Self-test results

Each BCC reports the status of all elements in the disk system, even if the BCC
does not have direct access to the element.
Additionally, the EEPROM on each BCC stores 2 Kbytes of configuration
information and user-defined data, including the manufacturer serial number, and
product number.

Hardware Event Monitoring
A hardware event monitor monitors the disk system and reports changes in
environmental status to Hewlett-Packard’s Event Monitoring System (EMS) for
HP-UX. Hardware event monitoring is an important tool for implementing high
availability. Using hardware event monitors, you can virtually eliminate
undetected hardware failures that interrupt system operation or cause data loss.
The EMS Hardware Monitors User’s Guide is available in Adobe® Acrobat®
format on the HP document web site, http://www.docs.hp.com/hpux/systems/.

Product Description

Components
User-replaceable components enable high availability and easy maintenance.
This section describes the following components:
■ Disks and disk fillers
■ BCCs and BCC fillers
■ Power supply/fan modules

Disk Modules and Disk Module Filler Panels
Disk modules, shown in Figure 3, contain 3.5-inch Low Profile Ultra 3 LVD
disks.
The disk module’s components are protected by a metal grill on the disk
module’s bottom side.
WARNING

Disks require careful handling and ESD precautions.

The plastic parts of the disk are safe to touch:
■ Extractor handle (A in Figure 3)
■ Latch tab (B)

You may also safely touch the top and bottom of the disk module without
damaging the disk module.
A metal grill protects exposed circuits against damage when the disk module is
laid circuit-side down on a flat surface.
The initial disk options for this product are 18-GByte, 36-GByte, and 73-Gbyte
10 K RPM disk drives. 18-GByte and 36-GByte 15 K RPM disk drives are also
supported. A label on the disk carrier shows the storage capacity and rotational
speed of the installed disk. Obtain information about the latest disk options from
HP sales representatives.
Caution

Product Description

Fillers must be installed in unused slots in order to maintain even
cooling for the installed disk modules.

Product Description

BCCs and BCC Filler Panels
BCCs (Bus Control Cards) plug into two slots in the back of the disk system.
Each BCC connects to both LVD (low voltage differential) buses inside the disk
system. In full bus mode (DIP switch 1 set to “|”), both BCCs have access to all
installed disks. The two SCSI buses are bridged. If either BCC fails and LVM
primary and alternate paths are defined, data can be accessed through the other
BCC. In split bus mode (DIP switch 1 set to “0”), the left BCC (as viewed from
the rear of the disk system), is on the high numbered bank (with disk slots 8, 9,
10, 11,12, 13, and 14) and the right BCC is on the low numbered bank (with disk
slots 0, 1, 2, 3,4, 5, and 6) of disk slots. See Figure 1.
Two SCSI ports (B in Figure 4) on each BCC provide dual LVD connections to
the same or separate hosts. If a host is connected to one of the BCC ports, an
LVD terminator must be connected to the other port on that BCC.

Product Description

Other features of the BCC are:
■ LEDs (C) indicating BCC status and bus configuration
■ DIP switches (D) on the rear panel:

1 Bus Mode (full or split bus)
2 Monitor Mode (SAF-TE or SES)
■ Locking thumbscrews (E)
■ Cam levers (F)

Product Description

BCC circuitry provides the following functions:
■ Bus expansion (LVD)
■ SCSI environmental services (see page 17)
■ System fault detection

A BCC filler panel (Figure 5) replaces the second BCC when redundancy is not
required.
Caution

The BCC filler panel maintains even cooling inside the disk
system when the second BCC is not present. A BCC filler panel
must be installed if the BCC is removed.

Product Description

■ Bus configuration (see “Setting DIP Switches” in Chapter 3)

Power Supply/Fan Module
Redundant, hot-pluggable 340-watt power supplies convert wide-ranging AC
voltage from an external main to stable DC output and deliver it to the midplane.
Each power supply has an internal fan, an AC receptacle (A in Figure 6), two
ejector handles (D) with thumbscrews (C), and 2 LEDs (B). Internal control
prevents the rear DC output connector from becoming energized when the power
supply is removed from the disk system.

Product Description

Internal circuitry triggers a fault when the internal fan or other part fails. At the
same time, the power fault LED (amber) illuminates, and, if enabled, the
hardware event monitor sends an event message. The power supply fan remains
on if other parts fail in order to maintain cooling air flow through the system. If
the fan fails, the power supply shuts down. The fan in the other working power
supply will increase to full speed to compensate for the failed fan. The failed
power supply/fan module must be removed and the replacement power supply/
fan module installed within two minutes. In the event of a failure, if a
replacement fan module/power supply is not available, leave the failed power
supply/fan module installed until you are ready to replace it. This should be done
to maintain proper cooling for the disk system.
Internal circuitry senses fan motion and triggers a fault when the speed of the
power supply’s internal fan falls below a critical level. At the same time, the LED
turns amber, and, if enabled, the hardware event monitor sends an event message.

Product Description

Power supplies share the load reciprocally; that is, each supply automatically
increases its output to compensate for reduced output from the other, and vice
versa. If one power supply fails, the other delivers the entire load.

Hardware/Software Requirements
The disk system is supported on the following operating systems:

Product Description

The disk system supports high availability through redundant components and
redundant connections to redundant hosts. Each SCSI port on a BCC can be
connected to a different host bus adapter in the same or different hosts. Internal
mirroring within the disk system is also possible.
Basic high availability topologies are described on the following pages. For
information about specific supported topologies, consult an HP sales
representative.
This disk system can hold up to 14 disk modules. The maximum number of disk
modules can be installed in either Full Bus Mode or Split Bus Mode. However,
host and disk drive addressing must be closely managed.
Full Bus Mode
The maximum of 14 disk modules can be supported in Full Bus Mode provided
there there is only one host bus adapter (HBA) connection and the HBA has the
SCSI address of 7.
If more than one host connection is required, the slot with the SCSI address
corresponding to the SCSI address of the additional host must not have a disk
module installed in it to avoid bus contention. For example, if two connections
are made to a Disk System 2300 with HBAs having SCSI addresses of 6 and 7,
then SCSI ID 6 (slot 7)must not have a disk module installed in it.
Note

SCSI address 15 should never be used by an HBA when
connecting to a Disk System 2300 because this address is reserved
on the SCSI bus for the enclosure services microprocessor.

Connecting one disk system to redundant hosts achieves system level high
availability. A single host bus adapter in each host is connected to a different port
in the disk system. With the disk system in full bus mode (switch 1 on), each host
can reach all the disks. If the right BCC (viewed from the rear of the disk system)
fails in this topology, there is still one path to the disks through BCC B. With the
disk system in split bus mode (two internal busses), the Disk System 2300
supports data mirroring between the two internal busses within the same disk
system. All connections from the host to the disk system are SCSI LVD cables.

Product Description

Topologies

Another type of high availability topology connects mirrored disk systems to
redundant hosts. Dual host bus adapters in each host are connected to mirrored
disk systems. With the disk systems in full bus mode (switch 1 on), each host can
reach all disks in both disk systems. If one of the disk systems fails in this
topology, all hosts will still have access to the data on the mirrored disk system.
All connections from the host to the disk system are SCSI LVD cables.

Due to SCSI ID limitations, daisy chaining of the Disk System 2300 is not
supported. The maximum storage capacity with this type of configuration is
approximately one Terabyte. This configuration does not provide any redundant
paths to the data, however there is some hardware redundancy provided by the
disk system hardware (i.e. power supply/fan modules and BCCs). This
configuration can be used for boot, root, swap, or file system storage. Using
Mirror/UX software, one or more mirrors can be created on the same hardware
path to provide a basic level of data protection.
In figures 7 through 11, any BCC shown with only one cable connection should
be understood to have a terminator attached to the other SCSI connector.

Product Description

The disk system can be connected to a single host with two host bus adapters
(HBAs) in a split bus configuration. See Figure 8. Each HBA will do reads and
writes to a maximum of seven disks. This configuration can provide a maximum
capacity of approximately 1.1 Terabytes. This configuration can also do basic
mirroring across different hardware paths, still providing a maximum data
capacity of approximately 0.5 Terabytes. This configuration can also yield a
maximum performance of 320 MB/s, since each BCC card is capable of 160MB/
s performance in a split bus mode.

Product Description

Data path redundancy can be secured with the configuration shown in Figure 9.
Using an additional host bus adapter (HBA) and the LVM software, alternate
links can be created, providing a redundant path to data for each disk system. In
addition, a separate mirror path can be created for data protection. This
configuration provides protection against any single component failure (i.e.,
cables, HBAs, disks). Figure 9 depicts connecting two disk systems to a single
host.
The only limit on the number of disk systems per system is the maximum number
of supported HBAs. For large configuration, it is recommended that multiple
CPUs have large amounts of memory to handle the system load. Each disk
system in this configuration is capable of 160MB/s performance. Due to SCSI ID
limitations, a maximum of 13 disks is supported per disk system (13 disks + 2
HBAs + 1 SES = 16 SCSI IDs).

Product Description

For customers with small data storage needs, a single disk system can be
connected to two hosts in a split bus mode. Each host can do reads and writes to a
maximum of seven disk modules. Each BCC can provide disk system status to
the host it is connected to. Each host can operate independently of the other.
System reboots and shutdowns do not need to be coordinated between the hosts.
In a split bus configuration, the two SCSI buses are physically isolated. Problems
on one bus are transparent to the other bus.

Product Description

A two-host configuration could be constructed using the Disk System 2300. Each
disk system could still be configured using mirrors. High availability software
will protect against a system failure. See Figure 11, above.

Product Description

The following terms have specific meanings in the context of this guide:

High availability (HA)
HA describes hardware and software systems that are designed to
minimize planned and unplanned downtime. High availability is
measured at the system level and stated as the percentage of time the
system is in a state to do useful work; for example, 99.95% availability
translates to four hours of downtime per year.

Hot-pluggable
Hot-pluggable signifies the ability of a component to be installed or
replaced without interrupting storage operations and within the
restrictions of the operating environment. All customer-replaceable
disk system components can be replaced under power. Adding or
replacing disks or BCCs may require the use of HP-UX commands to
manage file systems.

JBOD
Pronounced jay-bod, a JBOD (Just a Bunch Of Disks) is an enclosed
group of disks.

LVD
LVD (Low Voltage Differential) is a type of SCSI signalling that filters
out common mode noise by taking the difference of two low-voltage
signals. LVD supports cable lengths up to 25 meters including SCSI
cable lengths inside devices on the bus. The disk system’s connection
to the host is LVD.

PDU and PDRU
PDUs (power distribution units) distribute power from a single inlet to
multiple outlets. PRUs (power relay units) connect one or more PDU
inlets to a single on/off switch, such as a cabinet power switch. Units
that both distribute and switch power are referred to as PDRUs.

Product Description

Definitions

Ultra160 SCSI
Ultra160 is a SCSI interface that transfers 160 Mbytes/sec for wide
busses.

Product Description

Installation

Preparation
Before installing the disk system, make sure (1) electrical wiring, breakers, and
PDUs meet power needs, (2) the required support software is installed on the
host, and (3) if you are connecting the disk system to a V-class server, autotermination is enabled on the host bus adapter. This section covers all three of
these topics.

Electrical Requirements
All electrical wiring to the service point (plug) must be sized to carry the
appropriate inrush (20 amps per power supply) and steady state currents. See
Table 1 for examples.

Maximum RMS Current Drawn by One Disk
System

Adding disk systems to 120V circuits rapidly increases amp
requirements. Always make sure that the total current drawn does
not exceed circuit capacity.

Circuit breakers must be adequately rated for inrush and operating currents.
Hewlett-Packard recommends magnetic-type circuit breakers, which are capable
of handling large inrush currents for short durations (10 to 12 cycles) and are
rated adequately for steady state currents.

Choosing PDUs
Peak power requirements and PDU capacity affect the number of disk systems
that can be installed in a rack. For example, to install more than four disk systems
in Hewlett-Packard Rack Systems/E (HP Models J1500A(1.96M),
J1501A(1.60M), or J1502 (1.25M)), you must upgrade to 19-inch PDUs.
Besides rack density, the following factors can help you choose PDUs:
■ Redundant power source. To connect redundant power supplies to separate
■ Number of cords to the AC source. Using 30-amp PDRUs instead of 16-amp

PDUs reduces the number of cords to the wall.
■ Future needs. Installing surplus PDU capacity allows you to add disk system

units later.
■ Inrush margins. For installations that require four or more 16-amp PDUs,

Hewlett-Packard recommends HP 30-amp PDRUs (E7681A, E7682A) for
their inherent inrush protection.
■ On/Off switch capability. Some PDU/PDRU options support the use of a

single-point on/off switch. See Figure 12 and Figure 13.
The following tables show how many and what kind of PDU/PDRUs are needed
to install one or more disk systems in an HP rack. Data assumes 220V AC
nominal power and redundant PDU/PDRUs. For nonredundant configurations,
divide the number of recommended PDU/PDRUs by 2.

Installation

PDUs, install redundant PDUs.

Installation

Installing PDUs
The 19-inch PDUs and PDRUs can be installed vertically or horizontally in the
rack. Choose PDU/PDRU locations with the following guidelines in mind:
■ Place PDU/PDRUs within the reach of disk system cords.
■ Place PDU/PDRUs vertically whenever possible. See sample installations in

Figure 12 and Figure 13. Installing PDU/PDRUs horizontally interferes with
the ability to service disk systems that are behind the PDU/PDRU.
■ Place vertical PDU/PDRUs on each side of the disk system so that the cord

from either power supply does not cross over replaceable components in the
middle of the product.
■ To achieve maximum density in 2-meter racks, install 30-amp PDRUs on

Installation

Auto-Termination
Auto-termination is disabled when a shunt is installed over both pins on
the TP2 pinset. To enable auto-termination, remove the shunt entirely or
move it to only one of the pins. The result must be open pins, as shown
in Figure 14. Verify that auto-termination is enabled on the host system.
For other HBAs, check the documentation for your particular host bus
adapter.

8. Repeat the procedure above for the other rail.
9. Insert the disk system (with disk modules and power supplies
removed) onto the rails.

10. Move the disk system retention brackets to the frontmost set of
mounting holes.
This allows the disk system to install further back into the cabinet; and
so, allows the cabinet doors (if present) to close properly.

Installation

11. Push the disk system back into the rack until the disk system retaining
bracket is flush against the front column of the rack.
12. Bolt the disk system to the front column. Use the fifth hole from the
top of the front of the rail.
Figure 40. Bolting the Disk System to the Front Column of the Rack

Installation

Install the Disk System
1. Remove the power supply/fan modules to prepare the disk system for lifting:
a

Loosen the screws in each extractor handle of each power supply/fan
module with the chassis still in the box.

b Pull the extractor handles out from the center of the power supply to
disengage the it from the midplane. Pull each power supply/fan module
out of the chassis. Support the far end of the power supply/fan module
with your free hand as it clears the chassis.
c

Set the power supply/fan module aside, on an antistatic pad, to be
reinstalled later.

WARNING

Do not attempt to lift the disk system without the help of another
person or a lift device. Even without power supplies and disk
drives, the disk system weighs 54 pounds.

2. Remove the disk modules from the disk system. Place them aside on
the pink anti-static foam pad supplied with your disk system.
3. Carry the disk system to the front of the rack and slide the back end
onto the rails (Figure 38) with the help of another person or using a
lifting device. Push the disk system into the rack as far as it will go.
4. Secure the disk system as appropriate for the rail kit and cabinet at the
installation site.

Installation

Step 4: Install BCCs
The disk system comes with one or two BCCs, depending on the option
purchased. If you are installing only one BCC, you will install a BCC filler in the
open BCC slot.
1. Attach your ESD strap to ground.

2. Unpack the BCC from the accessories box and ESD bag.
WARNING

Do not touch the pins on the back of the BCC.

4. Open the BCC cam latches (C in Figure 41) by pulling them away
from the center.
5. Align the BCC alignment guides (E) with the slot, and insert the BCC
into the the left slot at the back of the disk system. Stop pushing when
the BCC meets the midplane.
6. Press the cam latches inward and flat against the center. The cam action
draws the BCC completely into the slot and seats the connector pins
on the midplane.
7. Tighten the locking screw (D).

Installation

3. Loosen the locking screws (D in Figure 41) if necessary on the BCC
cam latches.

8. If you have a second BCC, repeat steps 2 through 6, installing the
second BCC in the right slot.

Installation

9. If you do not have a second BCC, install the BCC filler as follows:
a

Unpack the BCC filler from the accessories box.

b Align the filler panel edges with the appropriate slot and insert the filler
into the open slot until the cam handles engage.
c

Press the cam handles toward the center of the BCC until they are against
the face of the filler panel.

d Tighten the locking thumbscrew (see Figure 42).

Installation

Step 5: Set DIP Switches
BCCs are shipped from the factory with all DIP switches (see Figure 43) in the
“|” position. The pull-out label on top of the disk system identifies each switch
position.
Caution

DIP Switch settings must be the same on both BCCs. If settings
differ, the disk system will fail its power-on self-test and the disks
will not be accessible through the second BCC.

Set dip switches as needed. See Chapter 3, Configuration, for switch definitions
and guidelines.
There is a switch bank that is recessed from the BCC bulkhead. Typically, they
do not need to be reset. The BCC must be removed from the disk system to
access this switch bank. See switch bank 2 in Chapter 3. Also see Tables 33 and
34 for switch settings and usage.

Installation

Step 6: Connect SCSI and Power Cables
1. Attach an LVD SCSI cable to SCSI port A or B, on one or both BCCs. (Sample
topologies appear in Chapter 1.)

2. Attach the other end of each SCSI cable to a host bus adapter. (See
bus configuration options in Chapter 3.)
3. Attach an LVD terminator to any empty SCSI port that is on a BCC
with a cable attached.
The terminators can be found in bags tethered to the BCC locking
thumbscrew(s).

5. Attach the other end of each power cord to a preinstalled PDU/PDRU.
Choose outlets according to the following guidelines:
— Redundancy. To extend the redundancy of the product, attach each cord to
a different PDU. This is represented in Figure 44 and Figure 45 by the
absence of duplicate letters in each disk system.
— Reliability. To avoid cascading faults for a group of disk systems that are
plugged into the same PDU, distribute redundant power cords to as many
different combinations of PDUs as possible. This is represented in
Figure 44 and Figure 45 by the least number of duplicate pairs of letters
among all disk systems. Cascading faults occur when a backup PDU is
overloaded with power surges after the primary PDU fails.
— Serviceability. Choose PDU locations that prevent power cords from
interfering with the removal and replacement of serviceable components.
Also leave a 6-inch service loop to allow for the rotation of PDRUs.
The letters A, B, C, D, E and F in the following diagrams represent independent
PDUs or PDU banks. The absence of duplicate letters in individual disk systems
indicates the products are using redundant PDUs. The minimal number of
duplicate letter pairs indicates the disk systems are protected against cascading
faults.

Installation

4. Plug a power cord into the AC receptacle of each power supply.

Installation

Step 7: Install Disk Modules
Caution

Touching exposed areas on the disk can cause electrical discharge
and disable the disk. Be sure you are grounded and be careful not
to touch exposed circuits.

Disk modules are fragile and ESD sensitive. Dropping one end of the disk just
two inches is enough to cause permanent damage. In addition, static electricity
can destroy the magnetic properties of recording surfaces. Grip disks only by
their handles (A in Figure 46) and carriers (D), and follow strict ESD procedures.

Installation

2. Put on the ESD strap and attach the other end to ground.
Caution

Disk modules are fragile. Handle carefully. Be careful to grasp the
disk module by its handle and avoid touching exposed circuitry.

3. Verify that the disk module extraction handle (A in Figure 46) is open
by placing a finger behind the extraction handle and pushing the latch
tab toward your finger.
4. Align and insert the disk module into its slot.
5. Push the disk module as far as it will go into the selected slot.
Note

Install disks left to right for easier insertion.

6. Close the cam latch by pushing the extraction handle toward the disk
until it clicks. The cam action draws the disk module completely into
the slot and seats the connecting pins on the midplane.
7. Repeat steps 4 through 7 to install additional disk modules.
8. Install disk fillers in the remaining slots.
Caution

Every slot must contain either a disk module or filler panel for
proper cooling.

Installation

1. Determine which slots, 1 through 14, will contain disk modules and which
will contain fillers.
— If DIP switch 1 is set to “|” (full bus mode), choose any slots for disk
modules or fillers. In full bus mode, the SCSI address 7 is reserved for the
host bus adapter. If more than one host bus adapter connects the disk
system to other hosts, then a disk module must be removed from the slot
whose SCSI address corresponds to the SCSI address of the additional
host bus adapter. The most host bus adapters supported on this disk
system is two.
— If DIP switch 1 is set to “0” (split bus mode), the left BCC is on the high
numbered bank (with disk slots 8, 9, 10, 11,12, 13, and 14) and the right
BCC is on the low numbered bank (with disk slots 0, 1, 2, 3, 4, 5, and 6)
of disk slots.
— At least one disk module must be installed.

Step 8: Turn on the Disk System
Caution

When starting up the disk system, do not override automatic spinup by issuing SCSI start commands to the drives. Doing so could
cause an overcurrent fault, requiring a power cycle to recover.

Press in the power/standby switch with the retracted tip of a pen or pencil to
power-on the array (see Figure 47). Allow 2 minutes for the disk drives and
controllers to complete their self-tests.
1. Press the power switch (A in Figure 47) to turn on the disk system.

2. Watch the system LEDs for confirmation that the disk system is
operational. The system power LED (B) should be green, and the fault
LED (C) should be off.
If the LEDs indicate a problem, refer to Chapter 4, Troubleshooting.
Note

Installation

An amber light that is on briefly when a component turns on is
normal. If this light remains on more than a couple of seconds, a
fault has been detected.

Step 9: Verify Devices on the Host
On an HP-UX host run IOSCAN (ioscan -f) and verify that the disks and BCC(s)
are listed in IOSCAN output. If the displayed “S/W State” is not “claimed,”
begin troubleshooting (see Chapter 4).

Sample IOSCAN
The example shows a fully loaded disk system. The BCC card is at hardware path

Configuration

Setting DIP Switches
Two DIP switches on left slot BCC determine bus architecture and some
bus behavior. If that BCC is removed, then the DIP switches on the
other BCC define the bus. See Table 8 for a description of switch
settings.
Table 8.

DIP Switch Settings

Switch Bank 1

Off - |

ON = 0

Creates a single bus of up
to 14 disk drives

Splits the bus into two
buses,
up to 7 disk drives each

mode is the default. For
HP-UX using EMS, set
to SES)

indicates it will go
offline

3 Bus Reset:
Hot Swap BCC

Automatically issues a
SCSI bus reset when a
BCC is removed or
inserted

Note

Configuration

1 Full Bus

Lets the host detect
change and determine
action

The switch settings on both BCCs must match. If the disk
system is being connected to an HP-UX system, the
switch should be set to SES mode. If the disk system is
being connected to a Netserver, the switch should be set
to SAF-TE mode.

If the BCC self-test detects any discrepancy, the buzzer sounds 4 or 5
times, and the BCC fault and system fault LEDs flash. If the system is
starting up, the disks do not spin up. If the system is operating, the disks
and second BCC continue to operate.

Configuration

Rationale
Sites choose DIP switch options according to their priorities and
preferences. High availability sites, for example, may want automatic
bus reset on whereas high performance sites may choose to turn it off.
The following table gives some of the typical reasons for choosing
specific DIP switch settings.
Table 9. DIP Switch Usage

Switch 1
1. Full Bus

Reasons to Set OFF
(|)

a. Split buses allow you to
mirror disks within the
disk system.

b. With two BCCs, full-bus
mode allows two external
connections to the bus.

b. Split-bus mode uses
fewer
IDs on the bus, improving
bus performance.

Switch 2

SAF-TE is required
for NT.

Reasons to Set OFF (|)

Configuration

a. Full-bus mode is the only
way to access all 14 disks
with one BCC.

c. Full-bus mode with two
BCCs gives redundant
environmental services.
2. SES/
SAF-TE

Reasons to Set ON
(0)

SES is required for
HP-UX .

Reasons to Set ON (0)

1. Bus ResetHot Swap
Disk

Automatic bus reset
reduces the chances of
data corruption and saves
the 30 to 60 seconds that
the host would spend
determining that a disk is
unavailable. Bus reset
signals the host to resend
outstanding I/O requests.

a. No bus reset reserves
bus control to the host.

2. Bus ResetPwr Fail

SCSI bus is held in reset
as power goes down, thus
avoiding data corruption

Bus control is restricted
to the host.

3. Bus ResetHot Swap
BCC

Automatic SCSI bus reset
reduces the chance of data
corruption when a BCC is
inserted or removed from
the disk system.

a. No bus reset reserves
bus control to the host.

b. No bus reset avoids
resetting the entire bus
for one disk.

Configuration

Disk Addressing
Each disk in the StorageWorks Disk System 2300 occupies a separate address
(SCSI ID) on the SCSI bus. Disk addresses range from 0 to 6 and 8 to 14 in fullbus mode (DIP switch 1 set to “|”). In split bus mode (DIP switch 1 set to “0”),
the left BCC (viewing the disk system from the rear) is on the high numbered
bank (with disk slots 8, 9, 10, 11,12, 13, and 14) and the right BCC is on the low
numbered bank (with disk slots 0, 1, 2, 3,4, 5, and 6) of disk slots. Address 7 is
reserved for host bust adapter(s). The BCCs take address 15.
Table 10 shows all target SCSI IDs for full bus and split bus modes.

Note

In split bus mode, the enclosure monitor circuitry on each BCC
utilizes SCSI address 15. This is allowable since each BCC is
connected to a separate SCSI bus. However, when the enclosure
configuration is in Full Bus mode, and the separate SCSI busses on
the midplane are connected together and there are two BCCs in the
enclosure, the secondary BCC does not connect to the SCSI bus.

Disk Slots and Addressing

In full bus mode, the SCSI address 7 is reserved for the host bus adapter. If more
than one host bus adapter connects the disk system to other hosts, then a disk
module must be removed from the slot whose SCSI address corresponds to the
SCSI address of the additional host bus adapter. The most host bus adapters
supported on this disk system is two.
In split bus mode, the loading sequence is from slot 1 to the right to slot 7 and
from slot 8 to the right to slot 14.
In full bus mode, begin loading the disk modules in slot 1 and continue installing
disk modules toward the right.

Configuration

The disk system has 14 available disk slots, SCSI addressing
does not follow a “1-to-1” relationship between slot positions
and SCSI addresses. Slot assignments and SCSI addresses are
shown in Figure 49.

Setting Up the Hardware Event Monitor

Troubleshooting

Overview
The following steps will help you identify and resolve disk system failures:
1 Gather information from all sources:
— Hardware event notifications (page 97)
— Disk system LED status (page 101)
— Online information tools (page 104)
2 Isolate the cause of the problem (page 104).
3 Correct the problem (chapter 5, Removal and Replacement).
4 Verify operational status with IOSCAN or other host utilities.

Troubleshooting

Event Notification (HP-UX Systems)
The EMS hardware event monitor polls
environmental services on the BCC and reports any
changes in the status of monitored components.
Depending on how the monitor is set up, you can
receive messages at the console, in e-mail, in a log
file, or through third-party applications. These
messages are likely to be the first indication of a
problem with a disk system.
Events are reported for changes in temperature,
voltage, and the status of replaceable components.
Messages identify five levels of severity:
An event that causes data loss, host system downtime, or
other loss of service. Host system operation will be affected if
the disk system continues to be used without correction.
Immediate action is required.

Serious

An event that may cause data loss, host system downtime, or
other loss of service if left uncorrected. Host system and
hardware operation may be adversely affected. The problem
needs repair as soon as possible.

Major Warning

An event that could escalate to a serious condition if not
corrected. Host system operation should not be affected and
normal use of the disk system can continue. Repair is needed
but at a convenient time.

Minor Warning

An event that will not likely escalate to a severe condition if
left uncorrected. Host system operation will not be
interrupted and normal use of the disk system can continue.
The problem can be repaired when convenient.

Information

An event that is expected as part of the normal operation of
the hardware. No action is required.

Troubleshooting

Critical

Event messages (see Figure 50) contain the following:
■ Message Data – Date and time the message was sent, the source and

destination of the message, and the severity level
■ Event Data – Date and time of the event, the host, event ID, name of the

monitor, event number, event class, severity level, hardware path, associated
OS error log entry ID
■ Error Description – Narrative information indicating the component that

experienced the event and the nature of the event
■ Probable Cause/Recommended Action – The cause of the event and

suggested steps toward a solution. This information should be the first step in
troubleshooting.
■ Annotation – The user-defined annotation associated with the specific disk

system

Status LEDs
LEDs indicate the status of the disk system itself and each of its
components (see Table 11). Green and amber system LEDs are visible
on the front of the disk system. They show that power is on (green) and
a fault has occurred (amber). Disk activity (green) LEDs are on the front
of the disk modules at the bottom of each disk module. Other LEDs are

Disk Module
Add or replace disks to increase storage capacity or eliminate faults. (See
Chapter 4 for troubleshooting procedures.) Disks must be Ultra-3 SCSI (LVD)
and 3.5 inches wide but can vary in capacity. For current information about
supported disks, consult an HP sales representative.
You do not need to turn off the disk system to replace a disk or filler.

Preparation (HP-UX 11.XX)
Removing or replacing a disk has consequences for the file systems and logical
volumes located on the disk. Before removing or replacing a disk, complete the
appropriate system administration for your environment and configuration.
Instructions for determining physical volume status and reducing and recreating
mirrored extents follow. For additional information, refer to your HP-UX guide,
How HP-UX Works: Concepts for the System Administrator.
The LVM commands in the following instructions assume the following:
■ All of the extents of the disk in use belong to mirrored logical volumes

created with the strict (-s) option.
■ The replacement disk is of the same or greater capacity as the disk being

replaced.
The correct set of instructions depends on whether the mirrored volume is active
and attached, or unattached. First, follow the instructions to determine the
volume status; then follow the instructions to replace the volume depending on
whether the volume is attached or unattached.

110 Removal and Replacement

At the host console, enter:
# vgdisplay
For example:
#vgdisplay /dev/vg00
If the volume group is not active, the host will display:
# vgdisplay: volume group not activated.
# vgdisplay: cannot display volume group

/dev/vg00

The following messages will appear if the disk is defective:
VGDISPLAY: WARNING: COULDN’T QUERY PHYSICAL VOLUME “/dev/dsk/c2t4d0”
THE SPECIFIED PATH DOES NOT CORRESPOND TO PHYSICAL VOLUME ATTACHED TO THE VOLUME GROUP
VGDISPLAY: WARNING: COULDN’T QUERY ALL OF THE PHYSICAL VOLUMES

If either of the above messages appears, follow the replacement instructions for
unattached physical volumes (page 114).
Otherwise, follow the instructions to determine if the physical volume is
attached.

To Determine If the Physical Volume Is Attached
Enter the vgchange command to activate the volume group.
The physical volume is unattached if a message similar to the following appears:
VGCHANGE: WARNING: COULDN’T ATTACH TO THE VOLUME GROUP PHYSICAL VOLUME
“/dev/dsk/c2t4d0”
THE PATH OF THE PHYSICAL VOLUME REFERS TO A DEVICE THAT DOES NOT EXIST, OR IS
NOT CONFIGURED INTO THE KERNEL.

Continue with the appropriate replacement instructions as follows:
■ If the physical volume is unattached, follow the instructions for replacing

unattached physical volumes (page 114).
■ If the physical volume is attached, follow the instructions for replacing

attached physical volumes (page 112).

Removal and Replacement 111

Removal and Replacement

To Determine If a Volume Group or Physical Volume Group Is
Active

To Replace Attached Physical Volumes
Use the following commands to reduce any logical volumes that have mirror
copies on the faulty disk and to recreate the mirror extents once the disk has been
replaced. Commands to recover from a host failure are included with most steps.
Note

The way that mirrors span several disks may not be duplicated
exactly. For cases where the original mirror layout must be
preserved, consider deactivating the volume group with the
vgchange command and using the procedure for replacing
unattached physical volumes.

1 Enter the following command to reduce the mirror:
# lvreduce -m -A n
For example, to reduce a two-way mirror:
# lvreduce -m 0 -A n /dev/vg00/lvol4 /dev/dsk/c2t4d0
or, for a three-way mirror:
# lvreduce -m 1 -A n /dev/vg00/lvol5 /dev/dsk/c2t4d0
If the host fails during this step, execute an lvdisplay command to determine
if the lvreduce command succeeded. If the command did not succeed, execute
the command again. Perform any other lvreduce commands that were not
executed before the system failed. Then proceed.
Note

An important effect of the lvreduce command is that the LVM
configuration backup file used by the vgcfgrestore command is
updated. If this replacement procedure is being performed now on
another host system and there is no need to execute any lvreduce
commands, then the configuration file is not updated. The LVM
configuration is correct on the physical volumes, however, so the
configuration file can be updated with the vgcfbackup command.

2 Physically replace the disk (see page 115).
3 Execute ioscan to verify that the new disk drive is accessible and a proper
replacement.
4 Enter the following command to restore the LVM configuration/headers to
the replaced disks from the backup of the LVM configuration:
# vgcfgrestore -n

112 Removal and Replacement

For example:

If the host fails, repeat the step to ensure all configuration data is written to
the new disk.
Note

If this replacement procedure is being performed now on another
host system and there is no need to execute any lvreduce
commands, then the configuration file can be updated with the
vgcfbackup command.

5 Enter the following command to attach the replaced disk to the active volume
group:
# vgchange -a y
For example:
# vgchange -a y /dev/vg00
6 Enter the lvextend command to transfer the mirrors onto the replaced disk. It
will take time to copy all of the original data to the mirrored extents. The
logical volumes are accessible to users’ applications for two-way mirroring
during this command.
# lvextend -m physical volume path
For example, for two-way mirroring:
# lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c2t4d0
For three-way mirroring:
# lvextend -m 2 /dev/vg00/lvol5 /dev/dsk/c2t4d0
If the host fails during step 6, execute an lvdisplay command to determine if
the lvextend command was successful. If the command did not successfully
execute, reissue the command. Perform any other lvextend commands that
were not executed before the system failed.
At this point, the system should be fully functioning.

# vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t4d0

To Replace Unattached Physical Volumes
Follow these instructions if the volume group is not active or if the physical
volume is unattached.
1 Replace the disk (see page 115).
2 Execute IOSCAN to verify that the replaced disk is accessible and a proper
replacement disk.
3 Enter the vgcfgrestore command to restore the LVM configuration/headers to
the replaced disk from the backup of the LVM configuration.
# vgcfgrestore -n character device file
For example:
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t4d0
4 Enter the vgchange command to attach the new disk to the active volume
group:
# vgchange -a y
For example:
# vgchange -a y /dev/vg00

blink with I/O activity to the disk. If you observe different results, refer to
Chapter 4, Troubleshooting, for probable causes.
8 Run IOSCAN on the host and verify that the replacement disk module is
“claimed.”
9 Restore file systems and data as needed (see Preparation (HP-UX 11.XX) on
page 110).

118 Removal and Replacement

Replace a BCC when troubleshooting shows that the card is faulty (see “Isolating
Faults” in Chapter 4).
There is no need to turn off the disk system to remove and replace a BCC. In full
bus mode with two BCCs, there is also no need to stop I/O to the disks. In other
configurations, however, the host must be notified that all disks on the affected
bus will be unavailable for I/O. Refer to Preparation (HP-UX 11.XX) on
page 110.
Caution

Touching the BCC pins can cause high energy
discharge and permanently damage the BCC.

Tools
ESD wrist strap (no hand tools are required to perform this procedure).
Whenever possible, follow ESD procedures.

10 Watch the BCC Fault LED (B in Figure 55). It should come on briefly and
then turn off. If the LED stays on and a buzzer sounds, the switch settings do
not match the settings on the peer BCC. For other solutions to a BCC fault,
see “Isolating Causes” in Chapter 4.

BCC Filler Panel
If a BCC is removed and a new one is not available, the BCC slot must be filled
to ensure proper cooling for the disk system. This is done with a BCC filler
panel.
For removal instructions for the BCC, see page 119.
Caution

122 Removal and Replacement

Do not remove the malfunctioning BCC until you have available
either a BCC filler panel or a replacement BCC.

Replace a power supply as soon as possible when troubleshooting indicates a
power supply failure (see “Isolating Causes” in Chapter 4). If a power supply
fails, the remaining power supply provides proper voltage to the disk system.
However, if the remaining power supply fails before the first power supply is
replaced, the disk system will turn off.
The power supply fan may continue to operate even when a power supply fails.
You do not need to turn off the disk system to replace a power supply.
Follow ESD procedures whenever possible.

Tools
ESD wrist strap (no hand tools are required to perform this procedure).
Whenever possible, follow ESD procedures.

Procedure
Caution

Do not remove a power supply from an operating product
until you have the replacement and are ready to install it.
An empty slot will cause uneven cooling and eventual
overheating.
The power supply may be hot to touch.

1 Disconnect the power cord from the power supply.
2 Loosen the thumbscrews on the power supply handles (A and B in Figure 57).
3 Rotate the handles out to disengage the power supply from the midplane.

AC Power Input
The disk system operates at 100-127 and 200-240 V AC, 50-60 Hz, single phase,
power factor corrected. Maximum current is 4.8 amps over the low voltage range
and 2.0 amps over the high voltage range. Average power consumption with
medium load (14 disks running idle) is 345 watts.

DC Power Output
■ Disk: +5 V and +12 V from power supply
■ BCC: +5 V and +3.3 V from power supply

Heat Output
1600 BTU/hr.

Environment
The following environmental specifications were type-tested under controlled
conditions. Hewlett-Packard maintains an active program of auditing production
products to make sure these specifications remain true when products are retested
under the same conditions. However, the limits of these specifications do not
represent the optimum for long, trouble-free operation and specifically are not
recommended for maximum satisfaction. The recommended conditions are
stated when appropriate.
■ Operating temperature: 5º C to 38º C (41º F to 100º F)

Recommended: 20º C to 25.5º C (68º F to 78º F)
■ Storage temperature: -40º C to 70º C (-40º F to 158º F)
■ Maximum gradient: 20º C per hour (36º F per hour)
■ Relative humidity:10% to 80% noncondensing, max. wetbulb at 28º C

Recommended:30% to 50% noncondensing
■ Altitude:3000 m (10,000 ft.)

Note

146 Reference

For continuous, trouble-free operation, the disk system should
NOT be operated at its maximum environmental limits for
extended periods of time. Operating within the recommended
operating range, a less stressful operating environment, ensures
maximum reliability.

The environmental limits in a nonoperating state (shipping and storage) are
wider:
■ Temperature: -40º C to 70º C (-40º F to 158º F)
■ Maximum gradient:24º C per hour (43.2º F per hour)
■ Relative humidity:15% to 90% noncondensing
■ Altitude:4600 m (15,000 ft.)

Acoustics
■ Sound power: 6.7 Bels
■ Sound pressure at operator’s position: 51.6 dB(A)
