Unit identification (UID) button

The unit identification (UID) button helps locate an enclosure and its components. When the UID button
is activated, the UID on the front and rear of the enclosure are illuminated.

NOTE:

A remote session from the management utility can also illuminate the UID.

• To turn on the UID light, press the UID button. The UID light on the front and the rear of the enclosure

will illuminate solid blue. (The UID on cascaded storage enclosures are not illuminated.)

• To turn off an illuminated UID light, press the UID button. The UID light on the front and the rear

Power on/standby button

The power on/standby button applies either full or partial power to the enclosure chassis.

• To initially power on the enclosure, press and hold the on/standby button for a few seconds, until

the LEDs begin to illuminate.

• To place an enclosure in standby, press and hold the on standby button for a few seconds, until

the on/standby LED changes to amber.

NOTE:

System power to the disk enclosure does not completely shut off with the power on/standby button.
The standby position removes power from most of the electronics and components, but portions of
the power supply and some internal circuitry remain active. To completely remove power from the
system, disconnect all power cords from the device.

A basic worksheet is included on the poster, but HP recommends creating and keeping more detailed
records.

Information recorded on the worksheet is used during the initial system setup and configuration, and
is helpful for future configuration changes and troubleshooting purposes.

NOTE:

If a supplier is installing or configuring your disk enclosure, provide them with the poster, and verify
that they complete the worksheet and record other important configuration and set up information.

Planning the storage configuration

Proper planning of the system storage and its subsequent performance is critical to a successful
deployment of the disk enclosure. Improper planning or implementation can result in wasted storage
space, degraded performance, or inability to expand the system to meet growing storage needs.
Considerations include:

• System and performance expectations

• Striping methods

• RAID levels

• Disk drive sizes and types

• Spare drives

• Array sizing (capacity)

NOTE:

For the minimum supported configuration, and other configuration information, see the QuickSpecs
for the disk enclosure.

System and performance expectations

To help determine the best way to configure your storage, rank the following three storage
characteristics in order of importance:

• Fault tolerance (high availability)

• I/O performance

• Storage efficiency

With priorities established, you can determine which striping method and RAID level to use.

As highlighted in the following section, some configuration methods offer greater fault tolerance, while
other configuration methods offer better I/O performance or storage efficiency.

Installation26

Striping methods

There are two methods for configuring the physical layout of the disk arrays:

• Vertical striping

• Horizontal striping

In a vertical configuration, a single RAID array uses one physical drive from each disk enclosure.

In a horizontal configuration, the RAID array uses multiple drives contained within one or more disk
enclosures.

RAID levels

Smart Array controllers use hardware-based RAID technology to group multiple disk drives together
in larger logical units (LUNs).

Key RAID methods include the use of data striping, data mirroring, and parity error checking. Data
striping improves speed by performing virtual disk I/O with an entire group of physical disks at the
same time. Mirroring provides data redundancy by storing data and a copy of the data. Parity error
checking provides automatic detection and correction if corruption of a physical disk occurs.

Depending on the host environment, the following RAID levels are supported with this disk enclosure:
RAID0, RAID1, RAID5 and RAID6 with ADG. Each level uses a different combination of RAID methods
that impact data redundancy, the amount of physical disk space used, and I/O speed. After you
create a LUN, you cannot change the RAID level.

The following table compares the different RAID levels.

Best practicesSummary

IMPORTANT: Do not use RAID0

for LUNs if fault tolerance is re­quired. Consider RAID0 only for
noncritical storage. RAID0 LUNs
provide the best performance for
applications that use random I/O.

In general, RAID1 virtual disks
provide better performance char­acteristics over a wider range of
application workloads than
RAID5.

RAID5 virtual disks can provide
performance advantages over
RAID1 for some applications that
use sequential I/O. Consider
RAID5 disks for applications with
high sequential I/O of records in
multiples of 8K bytes. The larger
the record size, the greater the
advantage.

RAID0

RAID1

RAID5

RAID0 is optimized for I/O
speed and efficient use of
physical disk capacity, but
provides no data redund­ancy.

RAID1 is optimized for data
redundancy and I/O speed,
but uses the most physical
disk space. IMPORTANT:
RAID1 uses about 100%
more physical disk space
than RAID0 and 70% more
than RAID5.

RAID5 provides a balance
of data redundancy, I/O
speed and efficient use of
physical disk space.

Striping and
parity

D2600/D2700 Disk Enclosure User Guide 27

Like RAID5, RAID6 gener­ates and stores parity inform­ation to protect against data
loss caused by drive failure.

RAID6

With RAID6, however, two
different sets of parity data
are used, allowing data to
be preserved if two drives
fail.

Disk drive sizes and types

RAID arrays should be composed of disk drives of the same size and performance capability. When
drives are mixed within a disk enclosure, the usable capacity and the processing ability of the entire
storage sub-system is affected. For example, when a RAID array is composed of different sized drives,
the RAID array defaults to the smallest individual drive size, and capacity in the larger drives goes
unused.

Spare disks

Best practicesSummary

RAID6 is most useful when data
loss is unacceptable but cost is
also an important factor. The
probability that data loss will oc­cur when an array is configured
with RAID6 is less than it would
be if it was configured with
RAID5. However, write perform­ance is lower than RAID5 be­cause of the two sets of parity
data.

Data redund­ancy

High

RAID meth­od

Striping and
parity

Spares are disks that are not active members of any particular array, but have been configured to
be used when a disk in one of the arrays fails. If a spare is present, it will immediately be used to
begin rebuilding the information that was on the failed disk, using parity information from the other
member disks. During the rebuilding process, the array is operating in a reduced state and, unless it
is a RAID6 or RAID1+0 array, it cannot tolerate another disk failure in the same array. If another disk
fails at this time, the array becomes inaccessible and information stored there must be restored from
backup.

After the rebuild of the data onto the spare is completed, when a replacement drive is inserted to
replace the failed drive, the system will automatically transfer the data from the spare onto the
replacement drive and return the spare to an available-spare state. It is important to note that the
process of rebuilding the spare or the replacement drive must not be interrupted or the process will
be aborted.

Some administrators have multiple spare disks, so that multiple arrays can experience failure and
successfully recover, before administrative intervention would be required to replace the spare or
failed disk. When assigning a spare to an array, the administrator chooses which arrays and how
many arrays are protected by that spare.

Array sizing

As a general rule, the greater the number of drives that are included in an array, the greater the
performance level that can be achieved. However, performance considerations are offset by fault
tolerance considerations. The greater the number of drives in an array, the higher the probability of
one or more disk failures in that array. The administrator must strike a balance between performance
and fault tolerance.

Installation28

Preparing the site

Preparing your site includes:

• Providing adequate structural support for the floor, page 29

• Providing adequate clearance space and ventilation, page 29

• Providing adequate and redundant sources of power, page 29

To ensure continuous, safe, and reliable operation of your equipment, place your system in an approved
environment.

Consider using the HP Enterprise Configurator (eCO) to help plan and configure racks and
rack-mountable devices. The eCO is available on the HP website:

nl

http://h30099.www3.hp.com/configurator.

Providing adequate structural support for the floor

Calculate the total weight of your equipment and verify that your site can support the weight.

For HP ProLiant server environments, consider using Rack Builder, a software tool that provides a
simplified method to planning and configuring racks and rack-mountable products. Rack Builder is
available on the Options tab of the ProLiant Home page of the HP servers website:

nl

http://www.hp.com/country/us/eng/prodserv/servers.html.

Providing adequate clearance space and ventilation

Be sure to provide adequate clearance around the front and back of the racks. Provide at least 63.5
cm (25 in) in the front of the rack to allow the doors to open fully and provide at least 76.2 cm (30
in) in the rear of the rack to allow for servicing and airflow.

If there are unused spaces in your rack, attach blanking panels across those empty spaces to force
the airflow through the components instead of through the open spaces.

Providing adequate and redundant sources of power

Make sure that you have two high-line power feeds installed near your computer. These two power
sources usually come from the same external power grid, but occasionally might originate from different
grids or even entirely different sources.

For protection against a power-source failure, obtain and include two uninterruptible power supplies
in your installation.

For power consumption specifications, see the QuickSpecs for your disk enclosure model.

D2600/D2700 Disk Enclosure User Guide 29

Racking the disk enclosure

The disk enclosure can be installed into most standard server racks. To verify that your rack is supported
for use with the disk enclosure, see the QuickSpecs for your disk enclosure model, available on the
D2000 website: http://www.hp.com/go/D2000.

CAUTION:

Install disk drives in the enclosures only after mounting the enclosures in the rack.

• An enclosure populated with disk drives is too heavy to lift safely.

• Movement of an enclosure during installation might damage the internal storage media of installed

disk drives.

Rack installation best practices

In addition to industry-standard recommendations, consider the following:

• Locate the heaviest items, such as uninterruptable power supplies (UPS) and additional disk enclos-

ures near the bottom of the rack.

• To make cabling easy, install the disk enclosures below the server.

• Install similar components next to each other in the rack. Because enclosures, switches, and servers

are of differing depths, if you have more than one of a device, mount those devices adjacent to
one another to accommodate working behind the rack.

WARNING!

To reduce the risk of personal injury or damage to the equipment, be sure that:

• At least two people lift the storage system during removal or installation if the weight exceeds

22.7 kg (50 lb). If the system is being loaded into the rack above chest level, a third person MUST
assist with aligning the system with the rails while the other two people support the weight of the
system.

• The leveling jacks on the rack are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizing feet are attached to the rack if it is a single-rack installation.

• The racks are coupled together in multiple-rack installations.

• Only one component in a rack is extended at a time. A rack might become unstable if more than

one component is extended.

• To prevent damage and to ease insertion of the device into the rack, support the weight of the

device and keep it level when sliding it into the rack.

Installation30

Racking procedures

1. Position left and right rack rails at the desired 'U' position in the rack, adjusting the rails to fit the

rack, as needed (1).

2. Secure rack rails to the front and back rack columns using screws. Make sure that the shoulders

of the screws fit inside the square or round holes of the rack (2).

NOTE:

If installing rails in a square hole rack, use larger-sized shoulder screws and pins for mounting.
If installing rails in a round hole rack, use smaller-sized shoulder screws and pins for mounting.

3. Slide the device into position on the rails (1) and then tighten the thumbscrews on the front of the

device to secure the device to the rack.

NOTE:

The rear ends of the rails have a bracket that must engage the device chassis to secure the rear
of the chassis to the rails.

D2600/D2700 Disk Enclosure User Guide 31

Installation32

Installing disk drives

CAUTION:

Install disk drives in the enclosures only after mounting the enclosures in the rack.

• An enclosure populated with disk drives is too heavy to lift safely.

• Movement of an enclosure during installation might damage the internal storage media of installed

disk drives.

CAUTION:

• Follow industry-standard practices when handling disk drives. Internal storage media can be

damaged when drives are shaken, dropped, or roughly placed on a work surface.

• When installing a disk drive, make sure the drive is fully seated in the drive bay.

• When removing a disk drive, press the release button and pull the drive only slightly out of the

enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10 seconds
before completely removing the drive from the enclosure.

Disk drives are hot-pluggable. A variety of disk drive models are supported for use, including
dual-ported SAS disk drives and single-ported SATA disk drives.

For more information about supported disk drives, see the QuickSpecs for your disk enclosure model,
available on the D2000 website: http://www.hp.com/go/D2000.

NOTE:

SAS and SATA disk drives can be installed in the same disk enclosure.

1. Unlatch and swing out the drive handle, and slide the drive into the enclosure.

2. Rotate the handle to the closed position when the drive is fully seated in the enclosure.

D2600/D2700 Disk Enclosure User Guide 33

3. Continue until all drives are installed.

IMPORTANT:

For proper airflow and cooling, a drive blank must remain installed in all unused drive bays.

Installation34

Installing 6Gb SAS controllers and preparing the servers

When preparing servers for the disk enclosure, be sure to do the following.

• Record information about the server and controller that will connect to the disk enclosure.

• Verify that the servers, Smart Array controllers, operating system version, and service packs are

supported for use with the disk enclosure. For more information, see the QuickSpecs for the your
disk enclosure model, available on the D2000 website: http://www.hp.com/go/D2000.

• Install all operating-system-specific service packs, patch kits, or other required tools.

• Install HP system management and monitoring tools, such as HP Systems Insight Manager (HP-SIM)

and the Array Configuration Utility (ACU).

• Install one or more Smart Array controller in the server that will access the disk enclosure. For in-

structions, see the documentation provided with the controller and the server.

NOTE:

For detailed installation and configuration information about the server, the controller, or software
tools, see the documentation provided with the server, controller, or software.

Connecting cables and power cords

Overview

Connecting cables includes the following steps:

1. Reading the Cabling best practices, page 36.

2. Cabling the disk enclosure to the controller, page 37.

3. Cabling cascaded disk enclosures, page 38.

4. Labeling cables using labeling kit, page 38.

5. Connecting power cords, page 39.

NOTE:

For examples of cabling scenarios, see Chapter 6 on page 49.

Cabling best practices

• Use the shortest possible cable between devices. Shorter cables are easier to manage and route

along the back of the rack. In addition, shorter cables reduce the possibility of signal degradation
that might occur over longer distances.

• Gather the cables in the rear of the disk enclosure to ensure that the cabling in the back of the

rack system does not interfere with system operation or maintenance. Bind the cables loosely with
cable ties and route the excess cables out of the way, along the side of the rack. When the cables
are tied together and routed down the side of the rack, system components and indicators are
easily visible and accessible.

• Attach a label near both ends of each cable to identify the device connected to that cable. Include

the device, device name, port, or other useful information.

• Use colored markers to color code both ends of each cable, to help visually identify a particular

cable without having to read or locate the label.

• In multipath configurations, you might want to loosely bind the matching pair of cables connecting

devices.

Installation36

Cabling the disk enclosure to the controller

To connect the first disk enclosure to the controller, use a standard mini-SAS cable.

IMPORTANT:

When connecting this disk enclosure to single-path HP Smart Array P212 or P411 6Gb SAS controllers,
the second I/O module (I/O module B) in the disk enclosure is not supported for use.

The following illustration shows an HP ProLiant DL380 G6 server with a two-port HP Smart Array
P411 controller connecting to Small Form Factor (SFF) disk enclosures. Your environment might include
a different model server, controller, or disk enclosure, but the cabling principles are the same. For
additional examples of cabling scenarios, see Chapter 6 on page 49

D2600/D2700 Disk Enclosure User Guide 37

Cabling cascaded disk enclosures

Use standard mini-SAS cables to cascade additional disk enclosures from the disk enclosure that is
connected to the controller.

As additional disk enclosures are connected to the first disk enclosure, they are assigned a box number.
The assigned box number is displayed on the 7-segment display on the rear of the disk enclosure.

IMPORTANT:

• The number of supported cascaded disk enclosures varies per disk enclosure model and installation

environment. For more information, see the QuickSpecs for your disk enclosure model, available
on the D2000 website: http://www.hp.com/go/D2000.

• When connecting this disk enclosure to single-path HP Smart Array P212 or P411 controllers, the

second I/O module (I/O module B) is not supported for use.

• Use provided color clues on the disk enclosure when cabling cascaded disk enclosures; for example,

connect “green” ports to “green” ports (connect I/O module A on one disk enclosure to I/O
module A on the additional disk enclosure).

The following illustration shows an HP ProLiant DL380 G6 server with an HP Smart Array P411
controller connecting to Small Form Factor (SFF) disk enclosures. Your environment might include a
different model server, controller, or disk enclosure, but the cabling principles are the same. For
additional examples of cabling scenarios, see Chapter 6 on page 49

Labeling cables using labeling kit

A labeling kit is provided with the disk enclosure. Label both end of each cable using the materials
in the supplied labeling kit.

Installation38

Connecting power cords

To protect the system from power-failure-related downtime, each disk enclosure ships standard with
a redundant power supply. Depending how you connect the power supplies to the power source,
you can eliminate downtime caused by power-related failures.

When connecting the power cables, use the power cables shipped with the disk enclosure. After
power is supplied to the disk enclosure, the power supply automatically senses the input voltage and
the power supply LED illuminates as solid amber.

Disk enclosure power supplies connected to:
one power source

Disk enclosure power supplies connected to:

Powering on the disk enclosure

After disk enclosures are physically installed and cabled, power on all devices and verify that they
are operating properly.

Power on best practices

Observe the following best practices before powering up the enclosure for the first time:

• Complete the controller installation in the server. See the controller documentation.

• Install the disk enclosures.

• Install disk drives in the disk enclosures so that the connected host controller can identify and

configure them at power-up.

• Connect the SAS cables and power cords to the enclosure.

Power on procedures

1. Apply power to each UPS.

2. Apply power to all disk enclosures by pressing and holding the power on/standby button on the

rear of the disk enclosures until the system power LED illuminates solid green.
The LED on the power on/standby button changes from amber to solid green, indicating that the

disk enclosure has transitioned from a standby state to fully powered.

3. Wait a few minutes for the disk enclosures to complete their startup routines.

CAUTION:

If power is applied to the server before the disk enclosures complete their startup routine, the
server might not properly discover the storage.

4. Power on (or restart) the server with access to the disk enclosures, start the operating system, and

log on as administrator.

CAUTION:

When you power on the server, the monitor might display a “New Hardware Found” message.

Included topics:

• Powering on disk enclosures, page 47

• Powering off disk enclosures, page 48

• Updating disk enclosure firmware, page 48

Powering on disk enclosures

IMPORTANT:

Always power up disk enclosures before controllers and servers. This ensures that the servers, during
their discovery, see the enclosure as an operational device. If you do not power up the disk enclosures
before powering up the controllers and servers, you will need to power down the servers, ensure that
the disk enclosures are powered up, and then power back up the servers.

1. Apply power to each UPS.

2. Apply power to the disk enclosures by pressing and holding the power on/standby button on

the rear of the disk enclosures until the system power LED illuminates solid green.
The LED on the power on/standby button changes from amber to solid green, indicating that the

disk enclosure has transitioned from a standby state to fully powered.

3. Wait a few minutes for the disk enclosures to complete their startup routines.

CAUTION:

If power is applied to the server before the disk enclosures complete their startup routine, the
server might not properly discover the storage.

4. Power on (or restart) the server with access to the disk enclosures, start the operating system, and

log on as administrator.

CAUTION:

When you power on the server, the monitor might display a “New Hardware Found” message.
Cancel out of this window to prevent the installation of unsupported software.

5. Verify that each component is operating properly.

D2600/D2700 Disk Enclosure User Guide 47

Powering off disk enclosures

CAUTION:

Be sure that the server is the first unit to be powered down and the last to be powered back up. Taking
this precaution ensures that the system does not erroneously mark the disk drives as failed when the
server is powered up.

IMPORTANT:

If installing a hot-plug device, it is not necessary to power down the enclosure.

To power off a disk enclosure:

1. Power down any attached servers. See the server documentation.

2. Power down the disk enclosures. Press and hold the power on/standby button on the rear of the

disk enclosure for three seconds or until the system power LED changes from green to amber.

3. Disconnect the power cords.

The system is now without power.

Updating disk enclosure firmware

After initial installation and periodically after that, verify that the controller, disk enclosure, and disk
drives are running on the latest available firmware. You can identify currently installed firmware
versions through the HP SIM and ACU software utilities.

Firmware updates on the controller, disk enclosure and disk drives, are performed using HP Smart
Components. For more information, see “Smart Components for firmware updates” on page 46.

IMPORTANT:

Before installing new firmware on the disk enclosure, be sure to study the release notes and installation

7 Troubleshooting

If the enclosure does not initialize

IMPORTANT:

After a power failure, the system automatically returns to the last-powered state (On or Off) when
A/C power is restored.

1. Ensure that the power on/standby button was pressed firmly and held for approximately three

seconds.

2. Verify that the power on/standby button LED is green.

3. Verify that the power source is working:

a. Verify that the power supplies are working by viewing the power supply LEDs. If necessary,

remove and reinstall the power supplies to verify that they are seated properly.

b. Remove and inspect AC power cords from both power supplies and reconnect them.

D2600/D2700 Disk Enclosure User Guide 57

Recognizing disk drive failure

In an HP enclosure, a steadily glowing fault LED indicates that a disk drive has failed. Other indications
of failed disk drives are as follows:

• ACU represents failed drives with a distinctive icon.

• HP SIM can detect failed drives remotely across a network. (For more information about HP SIM,

see the documentation on the Management CD.)

• ADU lists all failed drives.

• Operating System log files

For additional information about diagnosing disk drive problems, see the HP ProLiant Servers
Troubleshooting Guide.

Effects of a disk drive failure

When a disk drive fails, all logical drives that are in the same array are affected. Each logical drive
in an array might be using a different fault-tolerance method, so each logical drive can be affected
differently.

• RAID0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all non-

fault-tolerant (RAID0) logical drives in the same array also fail.

• RAID1+0 configurations can tolerate multiple drive failures as long as no failed drives are mirrored

to one another (with no spares assigned).

• RAID5 configurations can tolerate one drive failure (with no spares assigned).

• RAID6 with ADG configurations can tolerate simultaneous failure of two drives (with no spares

assigned).

Compromised fault tolerance

If more disk drives fail than the fault-tolerance method allows, fault tolerance is compromised, and
the logical drive fails.

Factors to consider before replacing disk drives

Before replacing a degraded drive:

• Open HP SIM and inspect the Error Counter window for each physical drive in the same array to

confirm that no other drives have any errors. For details, see the HP SIM documentation on the
Management CD.

• Be sure that the array has a current, valid backup.

• Use replacement drives that have a capacity at least as great as that of the smallest drive in the

array. The controller immediately fails drives that have insufficient capacity.

To minimize the likelihood of fatal system errors, take these precautions when removing failed drives:

• Do not remove a degraded drive if any other drive in the array is offline (the online LED is off). In

this situation, no other drive in the array can be removed without data loss.

• Exceptions:

• When RAID1+0 is used, drives are mirrored in pairs. Several drives can be in a failed condition

simultaneously (and they can all be replaced simultaneously) without data loss, as long as no
two failed drives belong to the same mirrored pair.

Troubleshooting58

• When RAID6 with ADG is used, two drives can fail simultaneously (and be replaced simultan­eously) without data loss.

• If the offline drive is a spare, the degraded drive can be replaced.

• Do not remove a second drive from an array until the first failed or missing drive has been replaced

and the rebuild process is complete. (The rebuild is complete when the Online LED on the front of
the drive stops blinking.)

Exceptions:

• In RAID6 with ADG configurations, any two drives in the array can be replaced simultaneously.

• In RAID1+0 configurations, any drives that are not mirrored to other removed or failed drives

can be simultaneously replaced offline without data loss.

Automatic data recovery (rebuild)

When you replace a disk drive in an array, the controller uses the fault-tolerance information on the
remaining drives in the array to reconstruct the missing data (the data that was originally on the
replaced drive) and write it to the replacement drive. This process is called automatic data recovery,
or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is likely to be
permanently lost.

Time required for a rebuild

• The time required for a rebuild varies considerably, depending on several factors:

• The priority that the rebuild is given over normal I/O operations (you can change the priority setting

by using ACU)

• The amount of I/O activity during the rebuild operation

• The rotational speed of the disk drives

• The availability of drive cache

• The model and age of the drives

• The amount of unused capacity on the drives

• The number of drives in the array (for RAID5 and RAID6 with ADG)

Allow approximately 5 minutes per gigabyte without any I/O activity during the rebuild process. This
figure is conservative, and newer drive models usually require less time to rebuild.

System performance is affected during the rebuild, and the system is unprotected against further drive
failure until the rebuild has finished. Therefore, replace drives during periods of low activity when
possible.

CAUTION:

If the Online LED of the replacement drive stops blinking and the amber fault LED glows, or if other
drive LEDs in the array go out, the replacement drive has failed and is producing unrecoverable disk
errors. Remove and replace the failed replacement drive.

When automatic data recovery has finished, the online LED of the replacement drive stops blinking
and begins to glow steadily.

Failure of another drive during rebuild

If a non-correctable read error occurs on another physical drive in the array during the rebuild process,
the Online LED of the replacement drive stops blinking and the rebuild abnormally terminates. If this

D2600/D2700 Disk Enclosure User Guide 59

situation occurs, restart the server. The system might temporarily become operational long enough to
allow recovery of unsaved data. In any case, locate the faulty drive, replace it, and restore data from
backup.

Handling disk drive failures

If the controller was configured with hardware fault tolerance, complete the following steps after a
disk drive failure:

1. Determine which physical drive failed. On hot-plug drives, an amber drive failure LED illuminates.

2. If the unit containing the failed drive does not support hot-plug drives, perform a normal shutdown.

3. Remove the failed drive and replace it with a drive that is of the same capacity. For hot-plug

drives, after you secure the drive in the bay, the LEDs on the drive each flash once in an alternating
pattern to indicate a successful connection. The online LED flashes, indicating that the controller
recognized the drive replacement and began the recovery process.

4. Power up the server, if applicable.

5. The controller reconstructs the information on the new drive, based on information from the

remaining physical drives in the logical drive. While reconstructing the data on hot-plug drives,
the online LED flashes. When the drive rebuild is complete, the online LED is illuminated.

8 Replacement procedures

Customer self repair (CSR)

Information in “Exploded view” on page 63 identifies hardware components that 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.

Parts-only warranty service

Your HP Limited Warranty might 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 travel and labor costs.

Best practices for replacing hardware components

The following information will help you replace the hardware components on your storage system
successfully.

CAUTION:

Removing a component significantly changes the air flow within the enclosure. Components or a
blanking panel 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 your management

utilities to detect any additional hardware problems:

• When you have confirmed that a component replacement is required, you might want to clear
the failure message from the display. This makes it easier to identify additional hardware
problems that might occur while waiting for the replacement part.

• Before installing the replacement part, check the management utility for new hardware problems.
If additional hardware problems have occurred, contact HP support before replacing the
component.

D2600/D2700 Disk Enclosure User Guide 61

Identifying the spare part

Parts have a nine-character spare part number on their label. For some spare parts, the part number
might be available in the management software utility. Alternatively, the HP call center will assist in
identifying the correct spare part number.

Replacing the failed component

CAUTION:

Components can be damaged by electrostatic discharge (ESD). Use proper anti-static protection.

• 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 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 might obstruct access to the component.

Carefully move any cables out of the way to avoid loosening any connections. In particular, avoid
cable damage that might be caused by:

• Kinking or bending.

• Disconnecting cables without capping. If uncapped, cable performance might be impaired by

contact with dust, metal or other surfaces.

Replacement procedures62

• Placing removed cables on the floor or other surfaces, where they might be walked on or oth­erwise compressed.
