Continue with standard roll back
The following steps result with the original volume, with its original name, returned to the state of
the rolled back snapshot. If the snapshot is part of a snapshot set, this is not recommended.
The volume rolls back to the snapshot, deleting any newer snapshots. The rolled back snapshot
remains intact underneath the volume and retains the data. Any data that had been added to the
volume since the snapshot was created is deleted.
1. If you rolled back an application-managed snapshot, use diskpart.exe to change the
resulting volume's attributes.
For more information, see “Making a Windows application-managed snapshot available”
(page 174) .
2. Reconnect iSCSI sessions to the volume, and restart the applications.
Create a new SmartClone volume from the snapshot
Instead of continuing with a standard roll back, you can create a new SmartClone volume, with
a new name, from the selected snapshot. This choice preserves any newer snapshots and any new
data in the original volume.
