3 Deployment types

The following types of deployments are supported:

• Single domain

In a single domain deployment, one path exists from the disk enclosure to the host. In a
single domain deployment, only one I/O module in the disk enclosure is used

• Dual domain

In a dual domain deployment, two paths exist from the disk enclosure to the host. In a dual
domain deployment, both I/O modules in the disk enclosure are used. Because dual domain
deployments provide two paths to the storage, access is ensured, even in the event of device,
cable, or power failure. In dual domain environments, dual-port disk drives are required.

• Server attached (single or dual domain)

In a server attached deployment, the disk enclosure is connected to a controller card installed
in a server. Several models of controller cards are supported for use with this disk enclosure.
For more information, see the QuickSpecs for the disk enclosure.

• Controller enclosure attached (single or dual domain)

In a controller enclosure attached deployment, the disk enclosure is connected to a
rack-mounted array controller enclosure. The controller enclosure is then connected to the
server or network. Several models of array controller enclosures are supported for use with
this disk enclosure. For more information, see the QuickSpecs for the disk enclosure.

NOTE: Cabling illustrations are provided elsewhere in this guide, showing a variety of example
deployments. See (page 43).

Recommended service levels and appropriate related services for your particular disk enclosure
model are listed on the QuickSpecs. For more information, see the Storage Services website:
http://www.hpe.com/info/storageservices.

Gathering and recording information

A brief worksheet is included on the getting started instructions that is shipped with the disk
enclosure. As you gather and identify the hardware and software components for your
environment, use the worksheet to record information about your components and your
configuration. Some information is easily obtained before installing the disk enclosure, while
some of the information is created during the configuration process.

A basic worksheet is included on the poster, but Hewlett Packard Enterprise 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.

Preliminary tasks 23

Storage planning 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; some
configuration methods offer greater fault tolerance, while other configuration methods offer better
I/O performance or storage efficiency.

Striping methods

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

• Vertical striping—the RAID array uses one physical drive from each disk enclosure.

• Horizontal striping—the RAID array uses multiple drives contained within one or more disk

enclosures.

RAID levels

Controllers use 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.

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

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.

26 Installation

Preparing the site

Preparing your site includes:

• Providing adequate structural support

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

For HPE 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 Hewlett
Packard Enterprise servers website: https://www.hpe.com/us/en/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 (UPS) in your installation. See the following URL for a list of available UPS:http://

www.hpe.com/servers/ups

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

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

Consider using the Hewlett Packard Enterprise Configurator (eCO) to help plan and configure
racks and rack-mountable devices. The eCO is available on the Hewlett Packard Enterprise
website: http://www.hpe.com/info/SimpleConfigurator.

Preparing the site 27

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 the disk enclosure, available
on the D3000 website.

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

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

• Movement of a disk 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 uninterruptible power supplies (UPS) and additional disk
enclosures 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 disk 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.

Rack Installation 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.

Front and Rear bottom edge of the rails must align with the bottom of EIA boundary in the
lowermost 'U'

NOTE: Rails are marked L and R with an arrow indicating the direction in which the rail
should be installed.

2. Use guide pins to align the shelf mount kit to the RETMA column holes.

3. To engage the rear, push the rail toward the back of the rack until the spring hook (1) snaps

into place.

4. To engage the front, pull the rail towards the front of the rack to engage the spring hook with
the RETMA column in the same manner as the rear spring hook.

NOTE: Make sure that the respective guide pins for the square or round hole rack align
properly into RETMA column hole spacing.

5. Secure rear of rack rail to the RETMA column with either the square- or round-hole shoulder
screws, provided in the plastic accessory bag.

6. Secure front of rail to the front RETMA column using the provided flat securing screw/guide
pin in the bottom screw position of the rail.

7. Slide the enclosure into position on the rails (1). Secure the chassis into the rack by tightening
the captive CTO screw behind the latch on the front left and right bezel ears of the chassis
(2).

CAUTION: The front CTO screw must be attached at all times when racked.

Racking the disk enclosure 29

8. The rear ends of the rails have a CTO bracket that must engage with the enclosure in order
to secure it to the rails.

Align the CTO bracket to the corresponding rear slot into the chassis. The movable bracket
can be slid forward or back to correct position. The provided screw will secure the bracket
and chassis to the rail.

NOTE: The provided screw must be secured tightly. Hewlett Packard Enterprise
recommends using a T25 driver.

9. When cabling the device, use holes provided in the rear rack rails, install tie wraps, and
route external cable(s) as required.

30 Installation

Installing disk drives in the enclosure

Disk drive options

Depending on the enclosure model, 12 or 25 disk drives can be installed in the enclosure.

A variety of disk drive models are supported for use, including dual-ported and single-ported
models. For more information about supported disk drives, see the QuickSpecs for the disk
enclosure, available on the D3000 website.

Disk drive guidelines

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, press firmly to make sure the drive is fully seated in the drive
bay and then close the latch handle.

• 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.

• Always populate hard drive bays starting with the lowest bay number. If only one hard drive
is used, install it in the bay with the lowest device number.

• Disk drives are hot-pluggable.

• SAS and SATA disk drives may be installed in the same enclosure, but can not be included

in the same RAID logical volume.

Installing a disk drive

CAUTION: To prevent improper cooling and thermal damage, operate the enclosure only when
all bays are populated with either a component or a blank.

1. Remove the drive blank.

2. Unlatch and swing out the latch handle on the drive. Then, slide the drive into the bay (1),

pressing firmly on the drive to seat it. Close the latch handle (2), pressing firmly until it locks
in place.

Installing disk drives in the enclosure 31

IMPORTANT: When a drive is inserted in an operational enclosure, the drive LEDs flash
to indicate that the drive is seated properly and receiving power.

3. Determine the status of the hard drive.

IMPORTANT: For proper airflow and cooling, a drive blank must remain installed in all unused

drive bays.

32 Installation

Installing SAS controllers or controller enclosures

When installing controllers or controller enclosures, be sure to do the following.

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

• Depending on your deployment, do one of the following:

For server connect deployments, install one or more Smart Array controllers in the

◦

server that will access the disk enclosure.

◦ For controller enclosure connect deployments, install or locate the controller enclosure

to which the disk enclosure will connect.

NOTE: For detailed installation and configuration information about controller cards or controller
enclosures, see the documentation provided with the controller card or controller enclosure.

Preparing the server

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

• Record information about the server and environment (server connect or controller enclosure
connect) that will connect to the disk enclosure.

• Verify that the servers, controllers, operating system version, and service packs are supported
for use with the disk enclosure. For more information, see the QuickSpecs for the disk
enclosure, available on the D3000 website.

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

• Install Hewlett Packard Enterprise system management and monitoring tools, such as HPE

Systems Insight Manager (HPE-SIM) and the Array Configuration Utility (ACU).

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

Installing SAS controllers or controller enclosures 33

Connecting SAS cables and power cords

Overview

Connecting cables includes the following steps:

1. Reading the “Cabling best practices” Page 34.

2. “Connecting SAS cables to the server or controller enclosure” Page 35.

3. “Connecting SAS cables to cascaded disk enclosures” Page 36.

4. “Connecting power cords” Page 37.

IMPORTANT: The following illustrations demonstrate connecting a disk enclosure to a server

with an installed controller. In your environment, the disk enclosure might connect to a controller
enclosure, which then connects to the host or network. Cabling restrictions may exist for the
different installation environments. For more information, see the user documents for your
controller or controller enclosure.

NOTE: For additional examples of cabling scenarios, see (page 43).

Cabling best practices

• Use supported SAS cables and power cords. A variety of cables and cable lengths are
supported for use with this disk enclosure. For more information, see the QuickSpecs for
the disk enclosure, available on the D3000 website.

• Use the shortest possible cable between devices. Shorter cables reduce the possibility of
signal degradation that might occur over longer distances. In addition, shorter cables are
easier to manage and route along the back of the rack.

• Gather 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 cables loosely
with cable ties and route the 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.

• Bind and support cables in a manner that eliminates stress on connectors and tight bends
of the cables. This prevents damage to the connector and cable, and ensures that the
connector remains fully seated in the port.

• 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.

34 Installation

Connecting SAS cables to the server or controller enclosure

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

IMPORTANT: When connecting this disk enclosure in a single-domain environment, only the
top I/O module (I/O module A) in the disk enclosure is supported for use.

Observe the following guidelines:

• Only use supported SAS cables with mini-SAS connectors.

• Ensure that the servers or controller enclosures are powered down and power cords are

disconnected before connecting SAS cables to the disk enclosure.

The following illustration demonstrates connecting a disk enclosure to a server with an installed
controller. In your environment, the disk enclosure might connect to a controller enclosure, which
then connects to the host or network. Regardless of environment, cabling principles from the
disk enclosure to the host are the same.

Note the following when connecting cables:

• P1 on the disk enclosure I/O module is treated as the SAS “in” port.

• P2 on the disk enclosure I/O module is treated as the SAS “out” port.

• In single-domain configurations, one cable path is created between the host, the primary

disk enclosure, and additional cascaded disk enclosures. (Shown)

• In dual-domain configurations, two cable paths are created between the host, the primary
disk enclosure, and additional cascaded disk enclosures.

Connecting SAS cables and power cords 35

Connecting SAS cables to cascaded disk enclosures

To cascade additional disk enclosures from the disk enclosure that is connected to the server or
controller enclosure, use standard mini-SAS cables.

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:

• When connecting this disk enclosure in a single-domain environment, only the top I/O module
(I/O module A) in the disk enclosure is supported for use.

• The number of supported cascaded disk enclosures varies per disk enclosure model and
installation environment. For more information, see the QuickSpecs for the disk enclosure,
controller, or controller enclosure, available on the Hewlett Packard Enterprise storage
website: http://www.hpe.com/info/storage.

Observe the following guidelines:

• Only use supported SAS cables with mini-SAS connectors.

• 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).

Note the following when connecting cables:

• P1 on the disk enclosure I/O module is treated as the SAS “in” port.

• P2 on the disk enclosure I/O module is treated as the SAS “out” port.

• In single-domain configurations, one cable path is created between the host, the primary

• In dual-domain configurations, two cable paths are created between the host, the primary

disk enclosure, and additional cascaded disk enclosures.

Connecting power cords

When connecting power cords, use the cords shipped with the disk enclosure.

The power cord should be approved for use in your country. The power cord must be rated for
the product and for the voltage and current marked on the electrical ratings label of the product.
The voltage and current rating for the cord should be greater than the voltage and current rating
marked on the product. In addition, the diameter of the wire must be a minimum of 1.00 mm2or
18 AWG, your maximum length may be up to 3.66 m (12 ft).

After power is supplied to the disk enclosure, the power supply automatically senses the input
voltage and the power supply LED illuminates as solid green.

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.

can use this time to properly shut down your storage sub-system.

WARNING! To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.

• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.

• Route the power cord so that it is not likely to be walked on or pinched by items placed
against it. Pay particular attention to the plug, electrical outlet, and the point where the cord
is attached to the disk enclosure.

Connecting SAS cables and power cords 37

Powering on the disk enclosure

After disk enclosures are physically installed and cabled, apply power to the enclosure by
connecting it to a live power source. Verify that they are operating properly.

Power on best practices

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

• Complete the server, controller, or controller enclosure installation. For more information,
see the server, controller, or controller enclosure user documents.

• Install the disk enclosures.

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

and configure them at power on.

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

Power on procedures

1. Apply power to each UPS, or plug the enclosure in to a live power source. The system power
LED illuminates solid green.

2. 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.

3. Apply power to the controller enclosure (if included in the configuration).

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

Diagnostic steps 51

Recognizing disk drive failure

In a Hewlett Packard Enterprise 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.

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

52 Troubleshooting

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.

◦ 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.

Recognizing disk drive failure 53

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 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 on 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.

9 Replacement procedures

Customer self repair (CSR)

Information in (page 57) 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 Hewlett Packard Enterprise Limited Warranty might include a parts-only warranty service.
Under the terms of parts-only warranty service, Hewlett Packard Enterprise will provide
replacement parts free of charge.

For parts-only warranty service, CSR part replacement is mandatory. If you request Hewlett
Packard Enterprise 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 Hewlett Packard Enterprise 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 Hewlett Packard
Enterprise support before replacing the component.

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 Hewlett Packard
Enterprise call center will assist in identifying the correct spare part number.

Replaceable parts

Replacing the failed component

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

• Always transport and store components in an ESD protective enclosure.

• Do not remove the components 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 components 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.

• Hewlett Packard Enterprise 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.

◦ Placing removed cables on the floor or other surfaces, where they might be walked on

or otherwise compressed.

Many electronic devices, including computers, generate RF energy incidental to their intended
function and are, therefore, covered by these rules. These rules place computers and related
peripheral devices into two classes, A and B, depending upon their intended installation. Class
A devices are those that might reasonably be expected to be installed in a business or commercial
environment. Class B devices are those that might reasonably be expected to be installed in a
residential environment (for example, personal computers). The FCC requires devices in both
classes to bear a label indicating the interference potential of the device as well as additional
operating instructions for the user.

This is a class A device.

FCC rating label

The FCC rating label on the device shows the classification (A or B) of the equipment.

Class A equipment

This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, might cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at personal
expense.

Modifications

The FCC requires the user to be notified that any changes or modifications made to this device
that are not expressly approved by Hewlett Packard Enterprise might void the user's authority
to operate the equipment.
