appears.
b) Modify the replication settings as needed, then click OK. These settings are described in the online help.
7. When you are done, click Finish.
• Storage Manager restarts the replications.
• Use the Recovery Progress tab to monitor the recovery.
Restart a Replication for a Single Restore Point
If a replication or Live Volume failed or was deleted, you can use the corresponding restore point to restart replication.
About this task
NOTE: Restarting replications removes replications that are configured in series (cascade mode) or that replicate the
same volume to multiple destinations (mixed mode).
Steps
1. Click the Replications & Live Volumes view.
2. Click the Restore Points tab.
3. Right-click the restore point that corresponds to the replication, then select Restore/Restart DR Volumes. The Restore/Restart
DR Volumes dialog box appears.
4. Enable or disable the replication options as needed, then click OK. These options are described in the online help.
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, 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 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.
