Recovering From A Vls6000 Disk Array Raid Volume Failure; Recovering From A Node Raid Volume Failure - HP StorageWorks 6000 - Virtual Library System User Manual

Recovering from a VLS6000 Disk Array RAID Volume Failure

If two or more hard drives have failed in a single disk array RAID 5 volume, a disk array RAID volume
failure has occurred. If three or more hard drives have failed in a single disk array RAID 6 volume,
a disk array RAID volume failure has occurred. See
information. A disk array RAID volume failure will corrupt all the data stored on the VLS storage pool
using that RAID volume, making it unrecoverable.
NOTE:
Only perform this procedure if a RAID volume failure has actually occurred. Other factors can result
in a false RAID volume failure being reported, such as a disk array being powered down or the SCSI
cabling to a disk array being disconnected at either end.
To recover from a disk array RAID volume failure:
1. Repair the failed RAID volume (for example, replace the failed hard drives in the RAID volume).
See Hard
2. Erase all the virtual media from the disk arrays and rebuild all the RAID volumes:
a. Select Storage Pools in the navigation tree, then select the storage pool that needs recovery.
b. Click Rebuild Storage Pool in the task bar.
c. Click Rebuild.
d. Click Yes to confirm.
3. Recreate the cartridges that existed on the VLS.
VLS cartridge configurations are stored on the disk array(s) and have been erased.

Recovering from a Node RAID Volume Failure

To recover from a node RAID volume failure, which occurs when both node hard drives fail:
1. Replace the failed node hard drives.
2. Install the operating system on the new hard drives and restore the VLS. See
