Mounting a Target Based Snapshot

a target based snapshot onto a provisioned system.
Note
Refresh the ASM once before trying to mount the TBS, to ensure that it selects
the latest available drive letter.

Select the Snapshot from the Enterprise View, right-click the snapshot and
choose an option to mount.
Note
Only snapshots with correct file system can be mounted.

Performing Roll back of a Mirror Snapshot
You cannot perform a snapshot rollback of a mirrored volume. To rollback the user
will need to perform the following steps:
1
Break the mirrored volume into basic non-mirrored volumes.
2
Logout any initiator connections to the volume.
3
Issue rollback from the CLI and wait for rollback to complete.
4
Once rollback is complete, login to the volume.
5
Recreate the mirror with full resynchronization.
If a full resynchronization is required during a mirror failover, existing snapshots
on the slave plex that is being resynchronized will be deleted.
Performing Roll back of a Target Based Snapshot

volume. So if changes were made to the original volume, all such changes will be
lost and data at the time of snapshot taken will be replicated to the original volume.

After taking the snapshot, login to the original volume and modify the data,. Log
out both parent and snapshot volume from all initiators.
2
Select the Snapshot from the enterprise view and right-click on target based
snapshot and select Roll back Snapshot set .

3 To verify if the progress of the roll back, select the target in the Enterprise view
and check the roll back status.

rollback is completed successfully.
