All the snapshots associated with the volume are left unchanged during a restore
operation.
It is possible to snapshot the volume before restoring it, so that the generated
snapshot can be used and the data is not lost.
It is possible to restore another snapshot (the target snapshot) from the source
snapshot. The target snapshot must be a snapshot of the same volume as the
source snapshot. The target snapshot's content and size will be identical to the
source snapshot's content and size. The target snapshot's lock/unlock status will
remain as it was.
Restoring a mirrored volume:
v Delete the mirror
v Restore the volume
v Re-establish the mirror
Note:
It is impossible to restore a volume while it is mirrored.
Example:
snapshot_restore snapshot=DBVolume.snapshot1
