Virtual Disks used to either revert back to or create a Virtual Disks copy of a point-in-time image that is
presented to a host as read-only or read-write. When PiT-based snapshots are enabled on the storage
array, the Snapshots tab is shown in vCenter, see figure PiT Snapshot View. The Snapshots view tab
provides the following commands:
• Create Snapshot Group
• Create Snapshot Image
• Create Snapshot Virtual Disks
• Change Settings
• Rename
• Delete
NOTE: Snapshot rollback and snapshot scheduling cannot be performed on the vCenter MD Plug-
in. Both features can only be configured in MD Storage Manager.
