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 an application-managed snapshot available" on page 218. 2. Reconnect iSCSI sessions to the volume, and restart the applications. 228 Using snapshots
