Disaster Recovery - HP StorageWorks 8000 - NAS Command Reference Manual

Disaster Recovery

Disaster can occur if the NAS head, storage array, or multiple devices are destroyed, or sustain
critical hardware failures. The following text commands are provided to implement the recovery
process. For detailed information on performing Disaster Recovery tasks, see the HP NAS 8000
Users Guide.
At a minimum, the recovery process requires a working NAS head with access to the DRF. The
recovery process attempts to restore the NAS head and the storage array based on the contents
of the DRF. In the case of a NAS head failure alone, no user data needs to be restored to the
storage array. In the case of a storage array failure, the recovery process attempts to format the
replacement array(s) to have the same LUN and volume group configuration as the current NAS
registry indicates. After the storage array is recovered, user data can then be restored from
backup tape. If both the head and storage array(s) fail, then the process used is to recover the
head first, then recover the storage array(s).
