Description

While failure of the NetBackup appliance hardware is rare, a failure can still strike the appliance for a number of reasons. Use the following steps as a guide to recovering your appliance from a hardware failure.

Symptoms of an appliance that has experienced a hardware failure:

  • A warning message is displayed on the hardware monitor page or via email if configured for SNMP.

  • The appliance does not boot or turn on. The system disk could be in a failed state.

  • The appliance boots and turns on but shows hardware errors for components from the main appliance or the storage shelves.

  • Virtual disks are degraded.

Step 1

Turn on the appliance.

Press the power button and LED on the control panel on the front panel to turn on the unit.

  • If the unit does not turn on, make sure that the unit has power.
  • If the unit still does not turn on, contact Veritas Technical Support for further assistance.

  • If the unit does turn on but with issues, proceed to the next step.

  • If the unit turns on with no issues, verify that all NetBackup services resume successfully.

Step 2

Determine the faulty hardware.

Perform the following actions to determine the faulty hardware:

  • Use the LED status indicators on the appliance to help determine if the hard disks and power supplies function correctly.

  • Check the hardware status from the Monitor > Hardware page on the NetBackup Appliance Web Console. You can also use the  Monitor > Hardware  commands in the NetBackup Appliance Shell Menu.

Step 3

Replace the faulty hardware.

Once you have determined the hardware that needs replacement, remove the faulty hardware and replace with a new unit.

User-replaceable hardware includes:

  • Power supplies

  • Hard disks

 

Note:

If you find that non-user replaceable hardware is faulty, contact Veritas Technical Support for further assistance.

Note: After Disk Replacement there will be Data copy Back / Rebuild Operations run in background so disks may not show online state immediately.Such Operation may take some time.

See Removing and replacing hardware components in the NetBackup Appliance.

Step 4

Verify that the hardware replacement is successful.

Perform the following actions to verify the status of the new hardware:

  • Use the LED status indicators on the appliance to help determine if the hard disks and power supplies are functioning correctly.

  • Run the Appliance Diagnostics Center from the NetBackup Appliance Web Console, then choose Perform a hardware health check .

Step 5

Verify that all NetBackup services have started.

Once you have verified that the status of the appliance hardware is healthy, check to make sure that all NetBackup services have resumed. All backup jobs resume once the appliance is turned on.

Note:

If a backup was in process when the power interruption occurred, the backup job likely failed.
