faults caused by electrostatic discharge, follow all safety precautions:

• Wear an anti-static wrist or ankle strap.

• Observe all standard electrostatic discharge precautions when handling

plug-in modules or components that have been removed from any anti­static packaging.

this from occurring:

• If your system comes with a rack stabilizer plate, install it.

• Fill all expansion cabinets, including all storage enclosures, from the

bottom to the top.

• Do not remove more than one unit from the rack at a time.

To help prevent serious injuries, load the components in the storage cabinet
in the prescribed order:

1. If present, install the r

cabinet.

2. Load the Fibre Channel (FC) switches in the storage cabinet at the

positions recommended in the System Installation Guide. The positions
can be adjusted according to a specific storage cabinet configuration.

3. Load and position the server(s) directly above the FC switches, if used in

your configuration.

4. The System Management Unit (SMU), if used in your configuration,

should be placed directly below the FC switches.

5. The first storage enclosure should be positioned at the bottom of the

storage cabinet. Additional enclosures are then placed above existing
enclosures, going towards the top of the system cabinet.

6. Once the bottom half of the storage cabinet has been filled, the top half

of the storage cabinet can be filled. Begin by placing a storage

o help ensure your safety and the safe handling of equipment, follow these

guidelines.

• Provide a suitable power source with electrical overload protection to meet

the power requirements of the entire system (the server/cluster, and all
storage subsystems and switches). The power requirements per cord are ­North America: 2 phase, 208Vac, 24A max; 1 phase 110Vac, 16A max.
Europe: 230Vac, 16A max.

• Provide a power cord that is suitable for the country of installation (if a

power cord is not supplied).

• Power cords supplied with this server or system may be less than 1.5m in

length. These cords are for use with a power distribution unit (PDU) which
is mounted inside the 19 inch rack. If you require longer cables, please
contact your local sales representative.

• Provide a safe electrical ground connection to the power cord. Check the

grounding of an enclosure before applying power.

• Only operate the equipment from nominal mains input voltages in the

range 100 - 240Vac, 6A max, 50/60Hz.

Caution: T
before undertaking servicing of the system.

• Unplug a system component if it needs to be moved or if it is damaged.

Note: F
use an external UPS to power the server. Also, each of the
redundant power supplies in the server and in the storage
subsystems should be operated from a different mains power circuit
in order to provide a degree of protection from mains power supply
failures. In the event that one circuit fails, the other continues to
power the server and the storage subsystem.

these guidelines.

• Each storage enclosure contains multiple removable hard disk drive (HDD)

modules. These units are fragile. Handle them with care and keep them
away from strong magnetic fields.

Safety information 21

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

• All supplied plug-in modules and blanking plates must be in place to

complete the internal circuitry and enable air to flow correctly around an
enclosure.

•

Using the system for more than a few minutes with modules or blanking
plates missing can cause an enclosure to overheat, leading to power
failure and data loss. Such use may invalidate the warranty.

• A loss of data can occur if a hard drive module is removed. Immediately

replace any modules that are removed. If a module is faulty, replace it
with one of the same type, of at least the same capacity and speed.

• Always shut down the system before it is moved, switched off, or reset.

• All storage enclosures are fitted with optical SFP transceivers. The

transceivers that are approved for use with supported storage enclosures
vary depending on the unit. The transceivers qualified for older systems
might not be approved for use with the most current storage systems. To
ensure proper operation of the server and the storage subsystems, use
only the approved replacement parts for each system. Contact the Hitachi
Data Systems Support Center for technical details about replacement
parts.

• Maintain backup routines. Do not abandon backup routines. No system is

completely foolproof.

In a single-server configuration, typically an embedded SMU manages the
system. In clustered systems and some single-node systems, an external SMU
provides the management functionality. In some cases, multiple SMUs are
advisable.

A Hitachi NAS Platform or Hitachi Unified Storage File Module system can
control several storage enclosures. The maximum number of storage enclosures
in a rack depends on the model of storage enclosures being installed. Refer to
the Storage Subsystem Administration Guide for more information on
supported storage subsystems.

The server supports FC switches that connect multiple servers and storage
subsystems. Some configurations require FC switches, but they are optional in
other configurations.

An external FC Switch is required when connecting more than two storage
subsystems to a standalone server or a cluster. An external FC Switch is
optional when connecting less than three storage subsystems to a stand alone
server or a cluster.

Contact customer support for information about which FC switches are
supported.

• Two hot-swappable fan assemblies

• Dual power supplies

• NVRAM backup battery pack

• Dual 2.5 inch disk drives

The pre-installed boards perform functions essential to the integrity of the

contents when the server is not receiving power (due to a power failure or a
short-term shut down). The battery pack is located behind the front bezel
cover of the server, on the left-hand side. The battery pack is hot-swappable
and can only be accessed after the front bezel has been removed.

Battery pack characteristics:

• Each server contains a single battery module. The module contains dual
redundancy inside.

• The battery pack uses NiMH technology.

• A battery pack has a two year operational life. A timer starts when a
server is booted for the first time, and the timer is manually restarted
when a replacement batter pack is installed. After two years of operation,
a log warning event is issued to warn the user that the battery pack should
be replaced.

• The battery pack is periodically tested to ensure it is operational.

• A fully charged battery pack maintains the NVRAM contents for
approximately 72 hours.

• When a new server is installed and powered on, the battery pack is not
fully charged (it will not be at 100% capacity). After being powered on, the
server performs tests and starts a conditioning cycle, which may take up
to 24 hours to complete. During the conditioning cycle, the full NVRAM
content backup protection time of 72 hours cannot be guaranteed.

• A replacement battery pack may not be fully charged (it may not be at
100% capacity) when it is installed. After a new battery pack is installed,
the server performs tests and starts a conditioning cycle, which may take
up to 24 hours. During the conditioning cycle, the full NVRAM content
backup protection time of 72 hours cannot be guaranteed.

• If a server is left powered off, the battery will discharge slowly. This means
that, when the server is powered up, the battery will take up to a certain
number of hours to reach full capacity and the time depends upon whether
a conditioning cycle is started. The scenarios are:

○ 24 hours if a conditioning cycle is started
○ 3 hours if a conditioning cycle is not started

er contains a battery pack. The battery pack maintains the NVRAM

During the time it takes for the battery pack to become fully charged, the
full 72 hours of NVRAM content protection cannot be guaranteed. The
actual amount of time that the NVRAM content is protected depends on
the charge level of the battery pack.

• A battery pack may become fully discharged because of improper
shutdown, a power outage that lasts longer than 72 hours, or if a server is
left unpowered for a long period of time.

If the battery pack is fully discharged:

○ Assuming a battery conditioning cycle is not started, a fully discharged

battery pack takes up to 3 hours before it is fully charged. If a battery
conditioning cycle is started, a fully discharged battery pack takes up to
24 hours before it is fully charged.

○ A battery conditioning cycle is started if the server is powered down for

longer than three months.

• A battery pack may be stored outside of the server for up to one year
before it must be charged and/or conditioned. After one year without being
charged and possibly conditioned, the battery capacity may be
permanently reduced.

If you store battery packs for more than one year, contact your
representative to find out about conditioning your battery packs.

• When preparing a server for shipment, if the NVRAM is still being backed
up by battery (indicated by the flashing NVRAM LED), the battery can be
manually isolated using the reset button. See

T

o access some server components, or field replaceable units (FRUs), you
must first remove the front bezel. Replace the bezel after the part
replacement is complete.

Bezel removal

The server bezel is held onto the server chassis through a friction fit onto
four retention posts, which are mounted to the chassis along the left and
right edges of the chassis. There are no screws or other fasteners.

Figure 10 Server front bezel with grasping areas

Procedure

o remove the bezel, grasp the front of the bezel by the grasping areas.

1. T

2. Gently pull the bezel straight out away from the server.

Replacing a fan

Fans provide for front-to-back airflow to be consistent with other storage
system components. The server continues to operate following the failure of
a single fan and during the temporary removal of a fan for replacement. A
failed fan must be replaced as soon as possible.

The fans are contained within three assemblies, which are located behind the
front fascia and are removable from the front of the server. All servers have
three fans (one fan per assembly).

The server's cooling airflow enables the system to operate in an ambient
temperature range of 10°C to 35°C when mounted in a storage cabinet with
associated components required to make up a storage system. The storage
system administrator is responsible for ensuring that the ambient
temperature within the rack does not exceed the 35°C operating limit.

Replacing the NVRAM backup battery pack

To replace the NVRAM backup battery pack in a server, you remove the old
battery and install the new replacement. Perform the battery pack
replacement as quickly as possible, and only when the new pack is present.

Note: If possible, shut down the serv
pack. Shutting down the server or migrating all of the EVSs to the other node
is not required. However, during the replacement procedure, there will be a
period of time when the NVRAM contents are not backed up by the battery
pack. If a power failure occurs during this period, the NVRAM contents may
be lost. The server uses one of two types of chassis:

• Type 1: Without a battery retention bracket.

• Type 2: With a battery retention bracket.

Replacing a power supply unit

You can replace a power supply unit (PSU) as a hot-swappable server
component. The server can operate on a single PSU if necessary, making it
possible to replace a failed PSU without shutting down the server. If a PSU
fails, it should be replaced as quickly as possible, because operating on a
single PSU means that there is no redundancy in that area, increasing the
risk of an interruption in service to clients.

LED indicators on each PSU indicate the PSU status.

erform this process to restart an unresponsive server from the server
operating system (OS) console. You generate a diagnostic log that can help
you better understand the problems. You can gain access either by using SSH
software to connect to the server's CLI or connecting to the server serial
port.

Procedure

1. Connect to the SMU using the ssh software.

2. From the siconsole, select the server.

• If the system fails to respond, go to step 3.

• If the system takes you to the server OS console, issue the command:
bt active, so you can view the display.

• If you are still at the siconsole, select q, press Return, and then
perform the following steps:

1. Connect directly to the MMB as manager using ssh.

2. If the connection succeeds, you are taken to the server OS

console, where you issue the command: bt active

Requirements

Downtime considerations for hard disk replacement

Downtime is required because hard disk replacement is not a hot
operation. Replacing a hard disk requires that you shut down the server,
disconnect the power cables from the Power Supply Units (PSUs), physically
replace server parts, and start the process of rebuilding the server's internal
RAID subsystem.

• Standalone server
The complete disk replacement process requires approximately 2.5 hours,

and the server will be offline during this time. You could restore services in
approximately 1.5 hours by restoring services before the second disk of
the server's RAID subsystem has completed synchronizing.

-swap

Caution: Early service restoration is not recommended.
second disk of the internal RAID subsystem has not completed
synchronizing, and there is a disk failure, you may lose data. Do not
restore services before the RAID subsystem has been completely
rebuilt unless the customer understands, and agrees to, the risks
involved in an early restoration of services.

• Cluster node
The complete disk replacement process requires appro

for each node, and the node will be offline during this time. You can,
however, replace a node's internal hard disks with minimal service
interruption for the customer by migrating file serving EVSs between
nodes. Migrating EVSs allows the cluster to continue to serve data in a
degraded state. Using EVS migration, each EVS will be migrated twice,
once away from the node, and then to return the EVS to the node after
hard disk replacement.

Step1: Performing an Internal Drive Health Check

The health check evaluates both internal disks to determine if there are any
pending disk failures. Perform the health check twice:

• Approximately one week before hard disk replacement to allow time to
resolve any errors before running the disk replacement procedure.

• When you start the hard disk replacement procedure to make sure the
disks are ready for the replacement.

The health check includes retrieving and evaluating the disk’s SMART (Self­Monitoring, Analysis, and Reporting Technology) information and reviewing
the server’s internal RAID subsystem status.

If you find errors on either of the two disks, note the disk and make sure
that the disk with the errors is the first one to be replaced. If both disks
have errors, contact technical support and escalate the errors based on the
health check output.

To run the health check:

If y

ou find that one disk has no errors, but the other disk does have

errors, replace the disk with errors first. If you find errors on both disks,
contact technical support and provide them with the smartctl output.

9. Perform the RAID subsystem health check to review the current status of

the RAID subsystem synchronization. Enter the following command:

cat /proc/mdstat outout

Group5-node1:~# cat /proc/mdstat

Step 2: Gathering information about the server or node

Before shutting down the serv
record information about the related IP addresses and check the status and
synchronization of the devices. To obtain this information:

Procedure

1. Log in to the Bali console. See

on page 81.

2. Select the serv

er or node that has the disks you want to replace.

3. R

ecord the IP Address of the system you choose.

4. Run the evs list command.

• For a single-node cluster or a standalone server, record the

administrative services EVS IP address.

88 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

• For a multi-node cluster, record all cluster node IP addresses.

5. R

un the chassis-drive-status command

6. Review the values in the Status and % Rebuild columns for each

device.
The response to the command should be similar to the following:

Device Status % Used Size (4k blks) Used (4k blks)
% Rebuild

------ ------------ ------ -------------- --------------

-----------­0 Good 32 3846436 1266962

or each device, the Status should be “Good” and the %Rebuild should

be “Synchronized.”

• If the values are correct, repeat the health check, as described in

Step1: Performing an Internal Drive Health Check on page 83.

•

If the values are not correct, run the trouble chassis-drive
command. If the command response displays “No
faults found,” repeat the health check, as

ys issues, resolve them if

Step 3: Backing up the server configuration

Backing up the server’s configuration for an internal or external SMU saves
the server’s configuration, including the SI configuration. When backing up a
server with an internal SMU, the configuration backup also includes a ZIP file
of the SMU configuration.

Procedure

1. Connect your laptop to the management Ethernet switch using an

Ethernet cable.

2. Log in to Web Manager.

3. Navigate to Home > Server Settings > Configuration Backup &
Restore.

4. Click backup to save the configuration file to your laptop.

5. Verify that the backup file is complete and make sure the file size is not 0

bytes

Step 4: Locating the server

Before shutting down the server/node to replace disks, you must physically
locate the server.

Procedure

1. Run the led-identify-node X command.
where X is the number of cluster node (the pnode-id) to identify.

The result of this command is that the server’s fault and power LEDs
(located on the left side of the server’s rear panel) flash simultaneously.

90 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

2. Ph

ysically locate the server that has the disks to be replaced. After you

have identified the server, press any key to stop the LEDs from flashing.

Step 5: Save the preferred mapping and migrate EVSs (cluster node only)

If replacing the hard disks in a standalone server, skip this step. If replacing
the hard disks in a cluster node, before shutting down the node to replace
disks, migrate the EVSs to another node. You can migrate an individual EVS
to a different node within the same cluster, or you can migrate all EVSs to
another server or another cluster.

The current mapping of EVSs to cluster nodes can be preserved, and the
saved map is called a preferred mapping. Saving the current EVS-to-cluster
configuration as the preferred mapping helps when restoring EVSs to cluster
nodes. For example, if a failed cluster node is being restored, the preferred
mapping can be used to restore the original cluster configuration.

Procedure

1. Connect your laptop to the customer’s network.

2. Using a browser, go to http://[SMU_IP_Address]/

where [SMU_IP_Address] is the IP address of the SMU (System
Management Unit) managing the cluster

3. Log into Web Manager as user manager. By default, the password is
nasadmin but this password may have been changed.

4. Navigate to Home > Server Settings > EVS Migration to display the
EVS Migration page.

Note: If the SMU is currently managing a cluster and at least one
other cluster or standalone serv

Hard disk replacement 91

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

er, the following page appears:

If this page does appear

, click Migrate an EVS from one node to

another within the cluster to display the main EVS Migration page.

If the SMU is managing one cluster and no standalone servers, the main
EVS Migration page appears:

5. Migr

ate the EVSs between the cluster nodes until the preferred mapping
has been defined. The current mapping is displayed in the Current EVS
Mappings column of the EVS Mappings section of the page.

6. Save the current EVS-to-cluster node mapping by clicking Save current
as preferred in the EVS Mappings section.

7. Migrate EVSs as required:

• To migrate all EVSs between cluster nodes:
a. Select Migrate all EVS from cluster node ___ to cluster node ___.

92 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

b. From the first drop-down list, select the cluster node from which to

migr

ate all EVS.

c. From the second drop-down list, select the cluster node to which the

EVSs will be migrated.

d. Click Migrate.

• To migrate a single EVS to a cluster node:
a. Select Migrate EVS ____ to cluster node ___.

b. From the first drop-down list, select the cluster node to migrate.
c. From the second drop-down list, select the cluster node to which the

EVS will be migrated.

d. Click Migrate.

Step 6: Replacing a Server’s Internal Hard Disk

Because physically replacing hard disks is not a hot-swap operation, you
must shut down the server and disconnect the power cables from the PSUs
before beginning physical replacement.

Procedure

1. Shut down the server.
Using Web Manager, go to the Server Settings page, and:

For a cluster node, navigate to Home > Restart, Reboot or

•

Shutdown Server > Shutdown.

• For a standalone server, navigate to Home > Restart, Reboot or

Shutdown Server > Shutdown.
Using the CLI, shut down the server using the following command:

•

shutdown –-powerdown –-ship -f

Hard disk replacement 93

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

2. W

ait for the status LEDs on the rear panel of the server to stop flashing,
which may take up to five (5) minutes.
If the LEDs do not stop flashing after five minutes, make sure the Linux
operating system has shut down by looking at your terminal emulator
program. If Linux has not shut down, enter the shutdown now command.

3. R

emove the power cables from the PSUs.

4. Remove the fascia. See

Bezel removal on page 50

for details.

5. Remove the fan.

Typically, hard disk “B” is replaced before hard disk “A.” Hard disk “B” is
behind fan assembly number 2 (the center fan), Hard disk “A” is behind
fan assembly number 1 (the left fan).

Caution: After one hard disk is replaced, y

ou must restart the
server and resynchronize its internal RAID subsystem before
replacing the second hard disk. See

new disk on page 100

for more information.

Step 7: Synchronizing server’s

6. Disconnect the fan power connector by pressing down on the connector’s

retention latch and gently pulling the connector apart.

94 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

7. R

emove the upper and lower fan retention brackets.

When replacing hard disk B, remove the upper fan retention bracket

•
and the lower fan retention bracket under fan assembly 2 (the center
fan assembly).

• When replacing hard disk A, remove the upper fan retention bracket
and the lower fan assembly bracket under fan assembly 1 (the left fan
assembly).

8. Remove the fan assembly covering the disk you want to replace.

When replacing hard disk B

, remove fan assembly 2 (the center fan

assembly). Hard disk B should now be visible.

Hard disk replacement 95

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

The hard disk is in a carrier (br

acket) held to the bottom of the chassis
by a thumbscrew on the right side and tabs that fit into slots on the
chassis floor on the left side.

Note: The carrier used for replacement hard disks ma

y be
different than the carrier holding the old hard disks. The new
carriers fit into the same place and in the same way as the older
carriers.

96 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

• Old carrier: the hard disk is mounted through tabs on the sides

of the carrier

.

New carrier: the hard disk is mounted through the bottom plate

•

of the carrier.

9. Disconnect the power and SATA cables from the hard disk.

10. Loosen the thumbscrew on the right side of the hard disk carrier

that the thumbscrew cannot be removed from the carrier.

. Note

Hard disk replacement 97

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

11. Gently lift the right side of the hard disk carrier and slide it to the right to

disengage the tabs on the left side of the carrier.

12. Once the disk carrier is completely disengaged from the chassis, remo

ve
it from the server, label it appropriately (for example, “server X, disk A”),
and store it in a safe location.

13. To install the replacement hard disk, lift the right side of the carrier until

you can insert the tabs on the left side of the disk carrier into the slots
on the floor of the server chassis.

98 Hard disk replacement

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

14. Mo

ve the carrier to the left until the ends of the tabs are visible and the

thumbscrew is aligned to fit down onto the threaded stud.

15. Tighten the thumbscrew to secure the disk carrier

the thumbscrew.

. Do not over tighten

16. Connect the power and S

ATA cables to the replacement hard disk.

17. Reinstall the fan in the mounting slot, with the cable routed through the

chassis cut-out.

Hard disk replacement 99

Hitachi NAS Platform 3080 and 3090 G1 Hardware Reference

18. Reinstall the fan retention brackets. Do not over tighten the screws.

19. Reconnect the fan cable.

20. If you replaced only the first hard disk, continue with the next step. If

you have replaced both disks, reinstall the fascia.

21. Reconnect the power cables to the PSUs.

When the server starts, the LEDs on the front of the server flash quickly,
indicating that the server is starting up.

Step 7: Synchronizing server’s new disk

After replacing a hard disk, the new disk in the server’s internal RAID
subsystem must be synchronized with the older disk.

Procedure

1. Wait until the LEDs on the front of the server slow to indicate normal

activity.

2. Use a serial cable connected to the serial (console) port of the server to

access the Bali console.

3. Once you have successfully logged in, select the server or node that has

the disks you want to synchronize.

4. Run the chassis-drive-status command, and look at the values in the
Status and % Rebuild columns for each device.

• The values in the Status column should be “Invalid.”

• The% Rebuild column should not display any values.

5. Run the script /opt/raid-monitor/bin/recover-replaced-drive.sh.
This script partitions the replacement disk appropriately, updates the
server’s internal RAID configuration, and initiates rebuilding the replaced
disk.
The RAID system rebuilds the disk as a background operation, which
takes approximately 50 minutes to complete. Events are logged as the
RAID partitions rebuild and become fully fault tolerant.

6. Monitor the rebuilding process by running the chassis-drive-status
command, and check the values in the Status column for each device.
The values in the Status column should be:

• “Good” for synchronized volumes.

• “Rebuilding” for the volume currently being synchronized.

• “Degraded” for any volume(s) that have not yet started the

synchronization process.
