Refresh a prepopulated volume group

Snapshot refresh can be used to refresh the data on a set of thin clone volumes from a volume group snapshot.

Any existing data on the set of volumes are discarded and the volumes are populated with the data from the specified snapshot.

Snapshot refresh operates at the volume group level or to a user specified subset of volumes within a volume group. Only thin clone volumes can be refreshed.

Snapshot refresh allows the user to:

• Examine the data on different snapshots without having to map a new set of volumes to any hosts.
• Discard any changes made to a set of thin-clone volumes and repopulate them with the original data from a snapshot.

You can use the command-line interface (CLI) to refresh the snapshot. For more information, see refreshfromsnapshot command.
