HP StorageWorks 12000, User Manual

Page: 216 / 266

1. One storage pool is automatically created. Recreate any other storage pools, as needed. See
Configuring Storage Pools .
2. Reassign the external LUNs to the same pools to which they were originally assigned. (This is
also described in
Configuring Storage Pools .)
CAUTION:
Do not use the Format checkbox option. This will destroy all existing cartridges in that pool.
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 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 Node RAID Volume Failure
To recover from a node RAID volume failure, which occurs when both node hard drives fail:
1. When restoring a primary node, power down all of the secondary nodes.
2. Replace the failed node hard drives.
3. Install the operating system on the new hard drives and restore the VLS. See Recovering from
Operating System Failure .
