General description
The DS2500 is a dual-redundant Fibre Channel (FC) loop storage system used on systems running HP-UX
operating system software. The DS2500 occupies 3 EIA units in a standard 19-inch rack. Up to 14
disk drives can be mounted in the front of the enclosure. Up to 4 DS2500s can be daisy-chained
together to create a storage ring.
Features
The DS2500 disk enclosure provides:
• Redundant power supplies and blowers
Only one operational power supply and one operational blower are required for the DS2500
to function.
• FC disk drives that can be added or replaced with the system on (although the affected file
systems must be taken offline)
• Environmental services sensors that monitor the disk enclosure and provide real-time error
reporting
• High-availability to minimize unplanned downtime
• Customer-replaceable components
Each DS2500 is connected to Host Bus Adapters (HBAs) through two independent Fibre Channel
Arbitrated Loop (FC-AL) buses, also known as loops, to provide no single point of failure (NSPOF). Each
disk drive connects to loop A through I/O module A, and to loop B through I/O module B. Figure 1
shows the maximum configuration of four DS2500s.
The disk enclosure supports high-availability requirements through the following features:
•
•
•
•
•
•
•
Hot-pluggable components
High-capacity, high-speed disks
Redundant, customer replaceable power supplies and blowers
Redundant I/O modules
Support for mirrored disks in the HP-UX environment

Components
I/O modules
Two I/O modules provide an interface between the disks and the host system. The I/O modules are used
to route data to and from the disks in a dual-loop configuration to eliminate a single point of failure.
Each disk drive is connected to both I/O module A and I/O module B (Figure 4-3). Each I/O module is
connected to an independent, external FC loop. I/O module A connects to loop A, and I/O module B
connects to loop B (see Figure 1 on page 14).
CAUTION:
Keep the loops completely separate to ensure that the failure of a single component (I/O module,
transceiver, or cable) does not stop data transmissions to active drives.

Figure 4 Redundant disk connections
The operation and function of both I/O modules are identical. Each I/O module has two ports that
can transmit and receive data for bidirectional operation. Port use and connections are configuration
dependent (see "Cables and cabling" on page 24). Each port is identified with a transceiver element
number, and its status is displayed on an LED (Figure 5). Port 1 is the bottom loop port, and port
2 is the top loop port.
• Port 2 LED—On indicates that a signal was detected at the top transceiver.
• Power LED—On indicates that power is present on the I/O module.
• Port 1 LED—On indicates that a signal was detected at the bottom transceiver.

6. Blower
Features
Only one operational power supply and one operational blower are required to keep the enclosure fully
functional. However, in the event of a component failure, HP strongly recommends that a replacement is
installed as soon as possible.
NOTE:
When a power supply fails, the associated blower is disabled.
The power supply circuitry monitors input voltage, current, and temperature. If it detects an unacceptable
level of any of these elements, the status indicator turns off and an error is reported to the EMU.
The EMU uses the temperature sensor signal to adjust the speed of the blowers. If one blower fails or
spins at a reduced speed, the speed of the other blower increases to provide adequate air flow.
Power supply and blower status indicator
A green LED on the blower (Figure 6-2) indicates the operational status of the power supply and the
blower. If either component fails, the LED turns off and an error alarm sounds. The failing component
should be replaced as soon as possible.
2500 Disk System user guide

Fibre Channel disks
Up to 14 HP FC disk drives can be installed in a DS2500. Only HP-supplied FC disk drives are
supported in a DS2500. Figure 7 shows an FC disk drive.
CXO6695B
Figure 7 HP FC disk drive
CAUTION:
To control air flow within the enclosure, you must install a disk drive or a drive blank in each bay.
To avoid overheating, never remove more than one disk or drive blank from an operating enclosure
at the same time.
Disk drive status indicators
Three status indicators (Ready, Online, and Fault) show the drive operational status (Figure 8). Table 2
provides a description of each status indicator.

Drive blanks
To maintain proper air flow in the enclosure, a drive blank must be present in each bay that does not
contain a disk drive.
CXO6824B
Figure 9 Drive blank
Cables and cabling
The DS2500 uses 50 micron (μm) diameter, multimode fibre cables.
The input port connects to an HBA or the previous enclosure in the loop, and the output port connects to
the next enclosure or an HBA on the loop.
Transceivers
The DS2500 uses a short-wavelength fiber optic transceiver called a Small Form-factor pluggable (SFP)
that does not pose a threat to the human eye. SFPs are installed in the I/O module ports.

Installing the DS2500, page 26
Verifying the installation, page 36
Adding drives to an existing DS2500, page 36
Preparing to install a DS2500
Before installing the DS2500:
• Ensure that electrical wiring and breakers meet the requirements described in Appendix B.
• Ensure that the supported HP-UX operating software is installed on the host. See "System
requirements" on page 15 for the minimum version of supported software.
• If you are adding to an existing storage system, ensure that the existing storage system is
operating properly before proceeding.
• Locate a No. 2 Phillips screwdriver.
HP recommends that you remove the rack side panel for easier access.
WARNING!
A DS2500 with all components installed weighs more than 29.5 kg (65 lb.) and requires a minimum of
two people to move. To safely and easily install the DS2500, using antistatic protection remove the
drive blanks, power supply/blower assemblies, EMU, and I/O modules. This reduces the weight of
the DS2500 to approximately 11.0 kg (24 lb). Even though a single person can lift this weight, the
DS2500 is difficult to install because of its physical size. Therefore, HP recommends that a minimum of
two people install an empty DS2500 in a rack.
Unpacking the shipping carton
Inspect the contents of the shipping carton. If anything is missing or appears damaged, contact an
HP sales representative.
The carton contains:
• DS2500 disk enclosure with disk blanks, I/O modules, EMU, and power supply/blower
assemblies
• Two power cords
• FC SFPs
• HP StorageWorks 2500 Disk System read me first document
• Snap-in rail kit
• Eight round-hole conversion pins

Installation
Converting the rails for round-hole racks
By default, the rack rails are configured for square-hole racks with load-bearing pins designed to
fit through the U-holes.
• If you are installing the disk enclosure in a square-hole rack, skip this section and continue with
"Installing the rails" on page 27. Do not remove the pins from the ends of the rails.
• If you are installing the disk enclosure in a round-hole rack, you must convert the rails as follows:
1. Locate the bag of miscellaneous hardware that is shipped with the rack rails.
2. Locate the eight round-hole pins.
3. Use a No. 2 Phillips screwdriver to remove the standard pins from the front and back ends of a rail.
4. Install four round-hole pins into the rail (Figure 11).
5. Repeat steps 3 and 4 on the other rail.
CXO8194A
Figure 11 Converting the rails for round-hole racks
Installing the rails
For each rail:
1. Determine where the rails will be mounted and use the rack template to mark the U-holes through
which the pins will extend.
2. Insert the front of the rail into the inside front column of the rack, making sure that the pins extend
through the U-holes marked in the previous step.
CAUTION:
Ensure that the scissor-type locking latches engage when the ends of the rail seat into the
rack columns, as shown in Figure 12 inset. Failure to do so could result in an unstable rail.

Reducing the enclosure weight
Before you install a DS2500, reduce its weight by removing the drive blanks, power supply/blower
assemblies, EMU, and I/O modules. The removal procedures in this section do not apply to an
operating enclosure, as they assume that there are no cables attached to the components, and no
power is connected.
WARNING!
A DS2500 with all components installed weighs more than 29.5 kg (65 lb) and requires a minimum of
two people to move. To safely and easily install the DS2500, remove the components as described in
this section. This reduces the DS2500 weight to approximately 11.0 kg (24 lb).
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper antistatic protection as described in the
documentation that shipped with your system.
Removing the drive blanks
To remove a drive blank:
1. Grasp the drive blank by the two tabs (Figure 15).
2. Lift up on the bottom tab and pull the blank out of the enclosure.

Installing the DS2500 in the rack
WARNING!
A DS2500 without components installed weighs approximately 11.0 kg (24 lb). Even though a single
person can lift this weight, the DS2500 is difficult to install because of its physical size. Therefore, HP
recommends that a minimum of two people install an empty DS2500 in a rack.
To install a DS2500:
1. From the front of the rack, slide the DS2500 onto the rails.
2. Secure the DS2500 to the front of the rack by tightening the four thumbscrews (Figure 19).

Error condition report (Er)
You can use the error condition report (Er) display group to determine the source of an error. When
an error occurs, the EMU generates an error condition report. You can use the push buttons view the
six-digit error condition report:
• The first two digits identify the component or element type (et) that is the source of the error,
displayed with both decimal points on (for example, 0.1.).
Table 6 lists the et codes.
• The next two digits identify the specific component or element number (en) that produced the
condition, displayed with the left decimal point off and the right decimal point on (for example,
01.).
• The last two digits is an error code (ec), displayed with both decimal points off (for example, 01).
For example, a left blower failure appears as:
0.3. 01. 03

Event monitor tools
The EMS Disk Monitor (disk_em) and the HP High Availability Storage System Monitor (ds_ses_enclosure)
monitor the disks in the DS2500. For information about these monitoring tools, see HP EMS Hardware
Monitors User’s Guide at the following web site:
http://www.docs.hp.com/en/diag.html
The monitoring tools report changes in disk status by sending an e-mail to the root account. These
messages provide early notification of a disk problem. Events reported include media errors, failed read
and write attempts, invalid commands, changed operating parameters, and failed diagnostics. Event are
assigned to one of the following severity levels:
• Critical—An event that causes data loss, host system downtime, or other loss of service. Continued
use the enclosure will negatively impact host system operation. Immediate action is required.
• Serious—An event that can 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.
• 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 enclosure can continue. Repair is needed but at a
convenient time.
• Information—An event that is expected as part of the normal operation of the hardware. No action
is required.
Example 1 shows an example of a hardware event notification. The notification provides the following
types of information:
• Message data—Date and time the message was sent, the source and destination of the message,
and the severity level of the event.
• Event data—Date and time of the event, the host, event ID, name of the monitor, event number, event
class, severity level, hardware path,and associated OS error log entry ID.
• Description of Error—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.

EMU error condition report
The EMU constantly monitors enclosure operation and notifies the user of conditions that could affect
operation. When an error condition is detected, the EMU:
•
•
•
•
•
Displays Er in the alphanumeric display
Generates an audible alarm (if enabled)
Updates the visual indicators
Generates a condition report
Reports the condition to the HP-UX application software
Severity levels
DS2500 error conditions are grouped into one of four severity types:
• Unrecoverable—This category is the most severe condition. It occurs when one or more enclosure
components have failed and some enclosure functions are disabled.
HP recommends implementing corrective action immediately for an unrecoverable condition.
• Critical—Occurs when one or more enclosure components have failed or are operating outside
of their specification, and normal operation of at least one component is impossible.
HP recommends prompt corrective action to prevent system degradation.
• Noncritical—Occurs when one or more enclosure components have failed or are operating
outside of their specifications, but normal operation of the enclosure is possible. Additional
errors, however, could affect the ability of the devices to operate correctly.
• Information—Advises you that a condition exists that could become an error and require
corrective action. In effect, an information condition provides an early warning, which enables
you to prepare to implement corrective action before a component fails.
Error condition reports
NOTE:
An error always generates a condition report. However, condition reports may also be generated
for circumstances other than errors.
The EMU stores each condition report in an error queue for at least 15 seconds after the error is reported.
This ensures that all errors are displayed in the event of multiple or recurring errors. The complete report
is stored in the error queue. When you correct the error, the condition report is removed from the queue.
You can the use the EMU push buttons to display the condition report in the alphanumeric display.
IMPORTANT:
Always record the 6-digit error code, and call your HP service representative for a plan of action.
See "Error condition report (Er)" on page 42 for information about viewing the error condition reports.
To decode the error condition report, see Appendix C.
Correcting the error removes the condition report from the error queue. An information error doesn't
require repair, and is removed from the queue after a fixed period of time.
Status indicators
LEDs indicating DS2500 status are located on the front and rear of each enclosure.

Catastrophic errors
The design of the DS2500 allows it to continue operating in the presence of faulty hardware. However,
a critically-high temperature in the enclosure can cause hardware failure and compromise data integrity.
To prevent catastrophic data loss and further damage to components, the following conditions cause the
DS2500 to shut down:
• A power supply removed from the enclosure
• No operational blowers
• An unacceptable temperature level in the enclosure
If any of these conditions exists, the EMU starts a timer to shut down the enclosure in 7 minutes. If the
condition is corrected before the 7 minute countdown is completed, the EMU aborts the shutdown
and normal operation resumes.
52
Troubleshooting
EMU temperature warning and shutdown operation
The EMU uses multiple temperature sensors to monitor enclosure conditions. A sensor is located in:
• Each power supply
• Each disk drive
• The EMU
An algorithm involving data from multiple sensors determines the temperature in the enclosure. The
following occurs when an unacceptable temperature condition exists:
• As the temperature approches a critical temperature condition, a noncritical alarm sounds to provide
time for corrective action before shutdown occurs.
• If the temperature reaches a critical level, the EMU activates the alarm and starts a timer which
shuts down the enclosure in 7 minutes.

6 Customer self repair
This chapter describes the procedures for replacing customer replaceable units (CRUs).
Customer self repair
The DS2500 is designed with three Customer Self Repair (CSR) parts to minimize repair time and allow
for greater flexibility in replacing defective parts. If during the diagnosis period an HP-authorized service
representative or support specialist determines that the repair requires a CSR part, HP will ship that part
directly to you for replacement. There are two categories of CSR parts:
• Mandatory—Parts for which CSR is mandatory. If you request that HP replace these parts, you
will be charged for the travel and labor costs of this service.
• Optional—Parts for which CSR is optional. These parts are designed for customer self repair. If,
however, you require that HP replace them for you, there may be additional charges, depending
on the type of warranty service designated for your product.
The DS2500 parts identified for optional CSR are:
• Disk drives
• Blowers
• Power supplies
There are no mandatory CSR parts in the disk enclosure.
NOTE:
Some HP parts are not designed for CSR. In order to satisfy the customer warranty, HP requires that an
HP-authorized service provider replace the part.
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 yourself.
Based on availability and where geography permits, standard HP CSR part delivery is next business
day. Ask your support specialist if same business day delivery options are available in your area.
Replacement instructions are included in this chapter, in spare kits, and at http://www.hp.com. If
further assistance is required, you can call the HP Technical Support Center and a support specialist
will help you over the phone.
For more information about HP's Customer Self Repair program, contact your local service provider. For
the North American program, see the HP web site http://www.hp.com/go/selfrepair.
CSR is available for most HP products currently under warranty. For more information on warranty
service see http://h18006.www1.hp.com/products/storageworks/warranty.html.
Parts-only warranty service
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.

Best practices for replacing hardware components
The following information will help you replace the hardware components on your DS2500 successfully.
Follow these tips any time you 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 installed until a replacement is
available.
Components can be damaged by electrostatic discharge (ESD). Use proper antistatic protection as
follows:
• Always transport and store CRUs in an ESD protective enclosure.
• Do not remove the CRU from the ESD protective enclosure until you are ready to install it.
• 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-antistatic (pink) plastic in an ESD
protective enclosure with ESD sensitive equipment.
• Wait 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 tighter than a 1.375-inch bend radius.
• Placing removed cables on the floor or other surfaces, where they may be walked on or
otherwise compressed.
• Disconnecting cables without installing a dust cap. If a cable is uncapped, its performance may
be impaired by contact with dust, metal or other surfaces.
CAUTION:
Fiber optic cables do not transmit data consistently when compromised by dust and debris. To protect
the connectors, always install the dust covers whenever a transceiver or a fiber cable is disconnected.
When connecting a transceiver or fiber cable, remove, but do not discard the dust covers or dust caps.
Verifying component failure
Confer with HP technical support to verify that the hardware component has failed and that you are
authorized to replace it yourself.
Multiple hardware failures can complicate component replacement. Check the System Event Analyzer to
detect any additional hardware problems.
Procuring the spare part
Parts have a nine-character spare component number on their label (Figure 29-1). The first six characters
(123479) identify the component; the last three characters (002 in this example) define the revision level.
The replacement component revision level must be the same as, or greater than, the number on the
component being replaced. The higher the revision level, the later the revision.

Returning the defective part
In the materials shipped with a replacement SCR part, HP specifies whether or not 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 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. HP pays all shipping and return costs for
CSR components, and determines the courier/carrier used.
Replacing a power supply/blower assembly
The power supply and blower are separately replaceable components. It is not necessary to remove the
power supply to replace a failed blower.
Before you begin
Always use proper antistatic protection as described in the documentation that shipped with your system.
You do not need to power off the enclosure to replace a power supply.
Be aware that the power supply may be hot to the touch.
Verify that the status LED is out on the power supply/blower assembly that you are replacing.
CAUTION:
You have only 7 minutes to complete the power supply replacement! Both power supplies must be
installed for the enclosure to cool properly. When a power supply is removed, the enclosure can
overheat and shutdown in approximately 7 minutes. If a power supply fails, leave it installed until
a replacement is available.
Removing a power supply
To remove a power supply:
1.
Disengage the power cord lock (Figure 30-1), and then disconnect the AC power cord from the
power supply.
TIP:
When removing the left power supply, ensure that the cord lock on the right power supply is
engaged to avoid inadvertently disconnecting the right power supply. Also, take care to avoid
disrupting the cables on the I/O module to the left of the power supply.
2. Lift up on the mounting latch (Figure 30-2), grasp the blower (Figure 30-3) and pull the power
supply out of the enclosure.
2500 Disk System user guide

Figure 30 Removing a power supply
Replacing a power supply
To replace a power supply:
1. Align the power supply with the enclosure opening.
2. Lift the module latch (Figure 31-1) and slide the power supply into the enclosure until it is
fully seated.
3. Remove the blower from the defective power supply and install it on the replacement power
supply (see "Removing a blower" on page 58).
4. Connect the power cord to the power supply and engage the power cord lock.
5. Verify that the blower starts and the power supply/blower assembly LED is on.

Replacing a disk drive
Before you begin
Always use proper antistatic protection as described in the documentation that shipped with your system.
Do not remove more than one disk drive or drive blank from an operating DS2500. Doing so impacts
air flow of the enclosure, and may cause data loss.
HP recommends installing a disk of equal or greater capacity, or a drive blank, as soon as possible.
Prevent possible data loss by verifying that the disk to be removed is in a failed state.
IMPORTANT:
When the system boots, HP-UX retrieves the loop ID and WWN of each disk and stores the information
for disk authentication. When you replace a disk drive, the authentication fails because the WWN has
changed. You must use fcmsutil to instruct the FC driver to ignore the authentication.
Removing a disk drive
Record the loop ID of the disk drive to be replaced. Use Table 12 to determine the loop ID based on the
enclosure ID and the bay in which the disk drive resides.

reports
Error condition report format
When the EMU alphanumeric display is Er, three sub-levels of information provide details about the error
condition: the element or component type, the specific component, and the error code. You can use
this information to determine the probable cause of the problem.
• The first sub-level displays the element type (et), which identifies the type of component affected.
See Table 20 to decipher the element type code.
• The second sub-level displays the element number (en), which identifies the exact component
affected.
• The third sub-level display provides an error code (ec), which defines a specific problem.
NOTE:
The conventions used to differentiate between the bytes of the condition report are:
• Element type—Period after each character (0.1.)
• Element number—Period after the second character (01.)
• Error code—No periods (01)
Table 20 lists the element type codes assigned to the DS2500 components.

Firmly grasp the EMU mounting handle and pull the EMU partially out of the enclosure.
CAUTION:
Do not remove the EMU from the enclosure. You must avoid putting any strain on the cables
or connectors.
2. Wait 30 seconds, and then push the EMU in until it is fully seated in the backplane. The EMU
should display any enclosure condition report within two minutes.
Transceiver error conditions
The format of a transceiver condition report is 0.F.en.ec, where:
• 0.F. identifies a transceiver error.
• en. identifies which transceiver is affected (see Figure 37).
• ec is the error code.
