Restoring a volume from a snapshot
You can restore a volume from a snapshot, and replace the data in the current volume with the volume data at the
time you created the snapshot. The snapshot still exists after the restore operation.
Note: Before a volume restore operation starts
, the group automatically creates a snapshot of the current volume.
Requirement: To
restore a volume from a snapshot, all members that contain data from a volume or snapshot
must be online.
Restriction: Yo
u cannot restore a template volume from a snapshot.
1. Disconnect any iSCSI initiators from the volume. Follow th
e instructions for your operating system and
initiator.
2. Click
Volumes in the lower-left panel, then expand Volumes in the far-left panel, and then select the volume.
3. Click
Set volume offline and confirm that you want to set the volume offline.
4. Click
Restore volume.
5. In the Restore Volume from Snapshot dialog box, select the snapshot and click OK.
6. In the Restore Volume Confirmation dialog box, choose
whether to set the volume online after the restore
operation completes (the default) and confirm that you want to restore the volume.
The restored volume has the same name and iSCSI ta
rget name as the original volume.
Cloning a snapshot to create a new volume
Cloning a snapshot creates a new standard volume, template volume, or thin clone volume with a new name and
new iSCSI target name, but with the same reported size, pool, contents as the original volume at the time you
created the snapshot.
The group allocates space equal to the volume reserve you s
pecify for the new volume. If you reserve snapshot
space for the new volume, the group allocates additional space.
The snapshot still exists after the clone operation.
