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.

• Avoid contact with backplane components and module connectors.

Safety and handling precautions

To ensure your safety and the safe handling and correct operation of the equipment, follow all of the safety precautions and instructions.

Caution: Observ can weigh 56 lb. (25 kg) or more. At least two people are required to handle and position a server in a rack.

Caution: There is a risk that a cabinet could fall o 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 component directly above the server and then fill upwards.

Electrical precautions

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 undertaking servicing of the system.

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

Note: F 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.

T 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.

• 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.

22 Safety information

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.

Component Description

Hitachi NAS Platform Hitachi Unified Storage File Module server

System management unit (SMU)

The system can contain a single server or several servers that operate as a cluster. Clusters that use more than two servers include two 10 Gbps Ethernet switches. Hitachi Data Systems supports two switches for redundancy.

For information about the physical configuration of a cluster configuration, see the Hitachi Unified Storage File Module and Hitachi NAS Platform System Installation Guide.

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 will continue to power the server and the storage subsystem.

A standalone server can operate without an external SMU, but all of the cluster configur

The SMU is the management component for the other components in a system. An SMU provides administration and monitoring tools. It supports data migration and replication, and acts as a quorum device in a cluster configuration. Although integral to the system, the SMU does not move data between the network client and the servers.

or additional data protection, it is recommended to use an

Storage subsystems

Fibre Channel (FC) switches

External Fast Ethernet (10/100) or Gigabit Ethernet (GigE) switches

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.

Contact Hitachi Data Systems Support Center for information about which FC switches are supported.

A standalone server can operate without an external Ethernet switch, provided that it uses an embedded SMU and there are less than three RAID subsystems attached.

A standalone server requires an external Ethernet switch if there are more than two RAID subsystems attached or if there are two RAID subsystems attached and an external SMU is used.

Each serv

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

acteristics:

• 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.

42 Hitachi NAS Platform server components

Hitachi NAS Platform 3080/3090 G2 Hardware Reference Guide

Page 43

• When a new server is installed and powered on, the battery pack is not

fully charged (it will not be at 100% capacit

y). 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

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:

○ The battery pack may permanently lose some long term capacity. ○ 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

Reset button (RST) on page

50 for the location of the reset button.

When preparing a serv

er for shipment or if it will be powered down for any length of time, it is important that the server has been shut down correctly before powering-off. Otherwise, if the server is improperly shut down, the batteries supplying the NVRAM will become fully discharged. This also

Hitachi NAS Platform server components 43

occurs if the system is powered down for too long without following the proper shutdown procedure.

Note: If the batteries become fully discharged, or the system is to be powered down for an extended period, see Powering down the server for

shipment or storage on page 85. Contact

Center for information about recharging batteries.

To replace the NVRAM battery backup pack, see Replacing the NVRAM

Hard disk drives

Hitachi Data Systems Support

The serv

er contains two hard disks, which are configured as a Linux SW RAID 1 pair, and they store server or cluster-related data. These hard disks are not part of the customer-usable data storage that is available to the server.

Hard disks are located behind the bezel on the left side of the chassis.

Note: F

ailed hard disks are hot-swappable, so a failed hard disk can be replaced without shutting down the server. However, there are serious risks in trying to swap a drive that is not failed.

front-to-back airflow to be consistent with other storage system components.

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 rack or 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.

The server continues to operate following the failure of a single fan and during the temporary removal of a fan for replacement. Replace a failed fan as soon as possible.

Caution: If a fan has failed, replace the fan as soon as possible to reduce the amount of time the serv

er is operating with reduced airflow.

The fans are contained within two assemblies, each containing a single v

ariable-speed fan. Fan assemblies are located behind the front bezel. Each fan assembly is secured to the chassis with two thumbscrews and a blindmate electrical connector; no tools are required to remove or install a fan assembly.

Two fan status LEDs provide fan status information. These LEDs are located behind the bezel on the right side of the chassis.

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.

To install a new NVRAM backup battery pack in a server, you must remove the battery caddy. If you have a replacement battery without a caddy, you can replace the battery inside the caddy, then reinstall the caddy.

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.

Replacing a hard disk

Before you replace a hard disk, determine whether the disk is truly bad.

y turning it clockwise.

Deciding on hard disk recovery or replacement on page 67 to mak

See that determination.

After you replace a hard disk, synchronize the new disk with the older disks in the system.

Deciding on hard disk recovery or replacement

A number of hard disk drive failures can occur. Some failures require disk replacement, others only require performing a recovery process. Use the process described in this section to help ensure that all partitions are recovered before proceeding with any further disk recovery or replacement procedures.

Before you consider replacing a hard disk drive, be sure you understand the following points:

• Do not attempt to replace an HDD unless you are instructed to do so by

Hitachi Data Systems Support Center.

• Failed hard disks are hot-swappable, so a failed hard disk can be replaced

without shutting down the server. However, there are serious risks in trying to swap a drive that is not failed.

• Do not assume that because the red LED is illuminated that a drive is

faulty. Under a RAID rebuild/recovery, the red LED would be illuminated. If the drive is failed and needs replacing, you can remove it from the server.

• Do not replace a drive that has not actually failed. If the disk shows signs

of failure, shut down the server before replacing the drive and restarting the server.

• There should be no reason to pull out a hard drive while it is in a known

good configuration, and doing so can potentially lead to data corruption.

• Unless you are certain the hard disk has failed, perform a disk recovery.

Replacing server components 67

Page 68

• Disk redundancy is unsupported while the disk is removed from the server.

Hard disks can fail for a number of reasons, including corrupt sectors or erroneous blocks of data. T of errors and they do not cause the server to fail.

More serious errors may cause a disk failure, causing one or both hard disks to fall out of the RAID. Should one partition of a disk fail, attempt a disk recovery. If a partition fails repeatedly, replace the hard disk. If all the partitions fall out of RAID, replace the failed drive.

Replacing a hard disk drive

The server contains two hard disk drives (HDDs). The HDDs are field replaceable when directed by Hitachi Data Systems Support Center.

Prerequisites

Obtain the new HDD or HDDs.

Before you replace a hard disk drive, be sure you understand the following points:

• Do not attempt to replace an HDD unless you are instructed to do so by

Hitachi Data Systems Support Center.

• Failed hard disks are hot-swappable, so a failed hard disk can be replaced

without shutting down the server. However, there are serious risks in trying to swap a drive that is not failed.

• Disk redundancy is unsupported while the disk is removed from the server.

Caution:

Do not remove or replace a non-failed (operational) HDD that is in a

•

working configuration; that means that the HDD is in use. Replacing a disk while the disk is in use can cause data corruption or disk damage.

• When ejecting an HDD, be certain that you only press the release button

for the one drive. If you press the wrong release button or both release buttons, the server will malfunction.

• If, by chance, you eject both of the HDDs, it is highly likely that the

system is corrupted. The best chance for data recovery is to do the following. Do not re-insert the drives. First, hard power down the server, and then re-insert the drives and reboot. When the system comes back online, confirm whether the NVRAM is recovered.

2. Identify the HDD to be replaced. Using Web Manager GUI, confirm which

HDD is to be replaced. The LED of the drive that requires replacement is red. If both drive LEDs

are red, see the SMU messages for guidance.

3. From the node's CLI, issue the command chassis-drive-clean-

configuration --disable --drive drive_letter

Where drive_letter is A or B, the letter of the drive you are replacing. For example, chassis-drive-clean-configuration --disable --

drive A

This command removes the drive from the RAID group, so you can continue with the rest of the steps

4. Remove the HDD:

a. Double-check that you are looking at the intended drive to be

removed.

b. Carefully press the button on the right side of the front of the disk tray

to release the retention latch handle.

Caution: Mak

e sure that you only press the release button for that

one drive.

c. Pull the retention latch handle outw

ard to disengage the disk from the

server.

d. Slide the disk tray out of the chassis.

5. Insert the replacement HDD:

a. Slide the replacement disk into the chassis until the retention latch

handle starts to close.

b. Press the retention latch handle towards the chassis to secure the disk

in the server. When the disk tray is fully seated, the retention latch handle will click into the closed position.

Caution: R

8. R

un the script /opt/raid-monitor/bin/recover-replaced-drive.sh, which will partition the disk appropriately, update the server’s internal RAID configuration, and initiate the rebuilding of the RAID pair.

Rebuilding the RAID pair ensures all data is accurate across both hard disks.

9. After the script has finished, follow these steps: a. Check the status logging into the NAS OS console (Bali).

b. Issue the command: chassis-drive-status

c. Repeat until all partitions are synchronized.

The RAID system rebuilds the disk as a background operation. The events are logged as the RAID partitions rebuild and become fully fault tolerant. The rebuild process can take up to an hour. The status indicator indicates normal operation (solid or flashing blue) once the RAID configuration has been repaired.

10. Log out.

11. Properly dispose of the used HDD. Do not attempt to re-install or re-use

the used HDD.

Synchronizing a 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-disk.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:

70 Replacing server components

Hitachi NAS Platform 3080/3090 G2 Hardware Reference Guide

Page 71

• “Good” for synchronized volumes.

•

“Rebuilding” for the volume currently being synchronized.

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

synchronization process.

7. Once the rebuild process has successfully completed, run the trouble chassis-drive command.

If the command response displays issues, resolve them if possible, or contact technical support for assistance.

If the command response displays “No faults found,” continue the disk replacement process by replacing the second hard disk.

8. Shut down the server.

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.

2. Move the retaining latch to the right (you may hear a slight click if the PSU moves when the latch disengages).

3. Using the handle on the PSU, pull the PSU out from the back of the server until you can completely remove the PSU from the chassis.

4. Insert the replacement PSU. The retention latch should click into position all the way to the left when the PSU is fully inserted. If the PSU that is not being replaced is receiving mains power when the replacement PSU is fitted, the fan on the replacement PSU becomes active.

5. Connect the power cord to the back of the PSU. The PSU should start as soon as the power connection is made. If the PSU does not start immediately, make sure the mains power circuit is live and that the other end of the power cable is connected to a live outlet.

Replacing an FPGA board as a FRU

Typically, when an FPGA board fails, the whole Hitachi NAS Platform server is replaced. However, in some cases with the HNAS 3080 and 3090 platform models, an FPGA board may be replaced as a field replaceable unit (FRU).

• Single stand-alone server using an embedded SMU for management

• Single stand-alone server using an external SMU for management

• Two-node cluster using an external SMU for management-replacing only

one node

• Two-node cluster using an external SMU for management-replacing both

nodes

This section highlights the requirements and consider nodes.

Requirements

Any personnel attempting the following procedures must have completed the necessary training before proceeding. Much of the process required for a server replacement is the same process covered in installation and configuration training. No personnel should attempt to replace a unit without adequate training and authorization.

Determine which replacement scenario is being encountered in advance. The replacement process is different for each scenario.

Acquire the temporary license keys before arriving onsite to expedite the server replacement. The license keys are necessary because they are based on the unique MAC ID for the server or cluster. New license keys are not required when replacing one server in a cluster.

Note: R management unit (SMU), so you must have a SMU installed before you can connect to a standalone server.

• 115,200 b/s

• 8 data bits

• 1 stop bit

• No parity

• No flow control

• VT100 emulation

Swapping components

The server can be replaced onsite. However, some components are not included in the replacement server that you receive. You must remove those components from the original server and use them in the replacement server. There are a minimum of four parts to be reused in the replacement server.

The components that can be swapped include:

The replacement server will have a new MAC ID. The new ID forces the need for new license keys regardless whether it is a single node or complete cluster replacement.

As part of a field replacement process, Hitachi Data Systems recommends that temporary keys be obtained to enable quick delivery and implementation. However, any temporary keys used must eventually be replaced with a permanent key. This is required for all field scenarios, except when replacing a single node in a cluster.

Upgrades

eplacement servers can be down or above a revision, and not at the expected level of firmware required at the customer site. An upgrade is typically required during the replacement process, which is not covered in this document. It is assumed that all services personnel performing a replacement have already been trained, and know where to get this information within their respective organization.

Replacing a single server with an embedded SMU

If a single server with an embedded SMU is non-functioning, and does not have a recent backup saved off platform, then a challenging and manual recovery process is necessary. If this circumstance is encountered, call the support organization for a copy of the system's latest diagnostics files. If available, these files can be used as a guide in reestablishing the system manually. The data and file systems will remain intact independent of the replacement and without a backup.

Note: R management unit (SMU), so you must have a SMU installed before you can connect to a standalone server.

Prerequisites

Obtain the necessary IP addresses to be used for the replacement serv Servers shipped from the factory have not yet had the nas-preconfig script run on them, so a replacement server will not have any IP addresses preconfigured for your use. You need IP addresses for the following:

• 192.0.2.200/24 eth1 (cluster IP)

• 192.0.2.2/24 eth1 (testhost private IP)

• 192.168.4.120/24 eth0 (testhost external IP, which might vary)

3. Use fc-link-speed to v

erify and, if necessary, configure the FC port

speed as required.; for example: a. Enter fc-link-speed to display the current settings.

host:$ fc-link-speed FC 1: 4 Gbps FC 2: 4 Gbps FC 3: 4 Gbps FC 4: 4 Gbps

b. Enter fc-link-speed -i port_number -s speed for each port.

host:$ fc-link-speed -i 1 -s 4 Set interface 1 link speed OK FC 1: 4 Gbps host:$ fc-link-speed -i 2 -s 4 Set interface 2 link speed OK FC 2: 4 Gbps host:$ fc-link-speed -i 3 -s 4 Set interface 3 link speed OK FC 3: 4 Gbps host:$ fc-link-speed -i 4 -s 4 Set interface 4 link speed OK FC 4: 4 Gbps

c. Enter fc-link-speed to v

erify the settings.

host:$ fc-link-speed FC 1: 4 Gbps FC 2: 4 Gbps FC 3: 4 Gbps FC 4: 4 Gbps

4. Use the fc-link-type command to configure the serv

er in fabric (N) or

loop (NL) mode.

5. Modify zoning and switches with the new WWPN, if you are using WWN-

based zoning. If you are using port-based zoning, the no modifications are necessary for the switches configurations.

6. Open Storage Navigator and reconfigure LUN mapping and host group on

the storage system that is dedicated to the server with the new WWPNs. Perform this step for every affected server port.

7. If the server does not recognize the system drives, enter fc-link-reset

to reset the fiber paths.

8. Enter sdpath to display the path to the devices (system drives) and

which hport and storage port are used.

9. Enter sd-list to verify the system drives statuses as OK and access is

allowed.

10. Enter span-list to verify the storage pools (spans) are accessible.

Note: In this instance, cluster is synon

11. Enter span-list-cluster-uuids span_label to displa

serial number (UUID) to which the storage pool belongs.

The UUID is written into the storage pool’s configuration on disk (COD). The COD is a data structure stored in ev information how the different SDs are combined into different stripesets and storage pools.

12. Enter span-assign-to-cluster span_label to assign all the spans to the new server.

13. Verify the IP routes, and enable all the EVSs for file services in case they are disabled.

14. Reconfigure any required tape backup application security.

15. Navigate to Home > Status & Monitoring > Event Logs, and click Clear Event Logs.

16. Navigate to Home > Status & Monitoring > System Monitor and

verify the server status:

• If the server is operating normally, and is not displaying any alarm

conditions, run a backup to capture the revised configuration, and then download another diagnostic to support. Permanent license keys for the replacement server are normally provided within 7 days.

• If the server is not operating normally for any reason, contact support

for assistance.

17. Confirm all final settings, IP addresses, customer contact information, service restarts, client access, and that customer expectations are all in place. Features such as replication and data migration should all be confirmed as working, and all file systems and storage pools should be online.

Replacing a single server with an external SMU

Note that if it is a single server with an external SMU that is nonfunctioning, and does not have a recent backup saved off platform, then a challenging and manual recovery process is necessary. If this circumstance is encountered, call the support organization for a copy of the system's latest diagnostics files, if available, to be used as a guide in reestablishing the system manually. The data and file systems will remain intact independent of the replacement and without a backup.

Note: R management unit (SMU), so you must have a SMU installed before you can connect to a standalone server.

Important: Set expectations up front with the customer that this will dela time to recovery, and that some aspects of the systems configuration might never be recovered.

Procedure

1. If the serv

er is online, using Web Manager (SMU GUI), navigate to Home

> Server Settings > Configuration Backup & Restore, click backup, and then select a location to save the backup file.

Ensure you save the backup file to a safe location off platform so that y

ou can access it after the storage system is offline.

The backup process performed by the embedded SMU will automatically capture both the SMU and server configuration files in one complete set.

2. Navigate to Home > Status & Monitoring > Diagnostics download

to download the diagnostic test results.

3. Navigate to Home > Server Settings > Firmware Package Management to verify the existing server (SU) firmware release level.

The server firmware version must match the failed server; otherwise, the serv

er cannot properly restore from the backup file. See the release

notes and system installation guide for release-specific requirements.

4. Navigate to Home > Server Settings > License Keys to check the license keys to ensure you have the correct set of new license keys.
