Re-Installing The Vls Licenses; Warm Failover; Recovering From A Vls9000 Disk Array Raid Volume Failure - HP StorageWorks 9000 - Virtual Library System User Manual

Re-installing the VLS Licenses

If one or more capacity bundles (or existing disk arrays), deduplication licenses, and/or replication
licenses were added to the VLS, you must re-install the VLS licenses.
To re-install the VLS licenses from Command View VLS (HP recommended method):
1. Locate the emails containing the license keys.
Your VLS license keys were emailed to you when you originally requested them. If you no longer
have these emails, contact HP technical support to obtain new license keys.
2. Log into Command View VLS.
3. Follow the
To re-install the VLS licenses from Command View TL:
1. Locate the emails containing the license keys.
Your VLS license keys were emailed to you when you originally requested them. If you no longer
have these emails, contact HP technical support to obtain new license keys.
2. Log into Command View TL.
3. Delete the VLS licenses in Command View TL.
4. Ignore the message saying to reboot the device.
5. Re-install the VLS license keys. See the HP OpenView Command View for TL User Guide.

Warm Failover

After any configuration or license change, the VLS automatically saves (within one hour) the updated
configuration and licenses to a hidden virtual cartridge stored on the back-end disk arrays. When
you replace the node or node hard drives, the VLS uses this information to automatically restore the
system to a configuration identical to what it had before. This automated process eliminates the need
to manually restore the configuration.

Recovering from a VLS9000 Disk Array RAID Volume Failure

If three or more hard drives have failed in a single VLS9000 disk array enclosure, a disk array RAID
volume failure has occurred. Each disk array enclosure is configured as one RAID6 volume. A disk
array enclosure 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 enclosure being powered down
or the disk array enclosure external cabling being disconnected at either end.
To recover from a disk array enclosure RAID volume failure:
1. Repair the failed RAID volume (for example, replace the failed hard drives in the RAID volume).
