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 dier depending on whether DR was activated.
• Recover from a destination volume that was not activated: If a source volume no longer exists, Storage Manager restores the data
from the destination volume by replicating it back to a newly created source volume. Once the replication is complete, Storage Manager
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: Storage Manager 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, Storage Manager maps the source volume to the selected server and restarts the replication
from the source volume to the destination volume.
NOTE
: To restore a volume to an alternate site, consult with technical support (see www.dell.com/support).
Volume Restore Limitations
The following limitations apply to the volume restore process.
• Restoring a volume removes replications that use it as a source volume.
• Restoring an original primary Live Volume volume using a managed replication removes the associated Live Volume.

Restoring a Live Volume and a Managed Replication
After a failover of a Live Volume with a Managed Replication, Storage Manager creates a new managed replication for the secondary Live
Volume. When the original primary Live Volume system is brought back online and the Live Volume is not restored, there will be two
managed replications for the Live Volume. Restoring the Live Volume will delete the managed replications on the original primary Live
Volume and keep the Managed Replication on the secondary Live Volume. Swapping the roles of the Live Volume will recreate the managed
replication on the original primary Live Volume and delete the Managed Replication on the secondary Live Volume.
