Restoring Replications and Live Volumes
A replication source volume or Live Volume primary volume can be restored from a replication destination volume or Live Volume
secondary volume. Restoring a volume is necessary when it has been deleted or DR has been activated and data has been
written to the activated volume.
Volume Restore Options
The options to restore a volume differ depending on whether DR was activated.
Recover from a destination volume that was not activated: If a source volume no longer exists, Unisphere Central
restores the data from the destination volume by replicating it back to a newly created source volume. Once the replication
is complete, Unisphere Central maps the new source volume to a selected server and restarts the replication back from the
source system to the destination system.
Recover from a destination volume that was activated: Unisphere Central recovers data from the destination volume,
including all new writes to the volume after it has been activated, to the original source volume. If the original source volume
is no longer there it will be re-created. Once the restore is complete, Unisphere Central maps the source volume to the
selected server and restarts the replication from the source volume to the destination volume.
