HP 9000 Virtual Library System - Manual (Page 126)

1. Navigate to the Manage Virtual Disks screen (see “Managing Disk Arrays” (page 124) ).

To narrow the list of disks displayed by disk array, enclosure, or revision, use the Select Disks
list, then select Update.

5. Review the warning and select Continue. The Update Firmware screen displays.
You can select Cancel to cancel the update process or select different disks.
6. If necessary, click the “De-select disks pending for update” link to remove certain disks from
the update process.
7. Reboot the system. See “Rebooting the System” (page 95) . The firmware update begins after
the reboot.
8. Go to http://<vls-hostname> (where <vls-hostname> is the hostname of the system
running the firmware update) to open the Disk firmware update progress screen and monitor
the progress.
If you are only updating SAS drives, when all of the disks have been updated to the new
firmware the VLS automatically reboots.
If you are updating any SATA drives, when all of the disks have been updated to the new
firmware a Done button appears. Do not select Done until you complete the next step.
9. Manually power cycle the disk arrays.
10. When the power cycle is complete, select Done. It may take several minutes until the system
is back online.
Resetting the Disk Array Information
Use the Reset Array Information function to reconstruct the display of array components in the
Command View VLS navigation tree following the removal of a disk array or enclosure.
CAUTION: Follow the procedure in “Removing VLS Capacity” (page 46) when removing an
array from the system or removing an enclosure from an array.
1. Navigate to the Manage Virtual Disks screen (see “Managing Disk Arrays” (page 124) ).
2. Select Reset Array Information from the task bar.
The screen provides a caution about resetting the disk array information.
3. Click Accept.
The screen displays a message that the reset has completed successfully.
Setting the RAID Mode
If your VLS is located at a remote data center and failed hard drives cannot be replaced in a timely
manner (48 to 72 hours), you can set the global VLS RAID6 configuration to include a hot-spare
for each RAID set. This feature allocates one spare hard drive per enclosure that will automatically
take over for a failed drive. After you replace the failed drive, the new drive becomes the spare.
CAUTION: This feature requires running the Rebuild All Storage Pools operation. Rebuild All
Storage Pools destroys all current virtual tape cartridges in the system. HP recommends only
changing this mode on a new installation before creating any virtual cartridges.
To change the RAID mode, in Command View VLS:
1.
Navigate to the Manage Virtual Disks screen (see “Managing Disk Arrays” (page 124) ).
2. Select Set RAID Mode from the task bar.
