Snapshot Manager for Data Center discovers all the HPE RMC volume sets and their snapshot sets.

Create snapshot

HPE RMC allows you to take snapshots of the entire volume set at once. The result of a create snapshot operation is a snapshot set that contains snapshots of every volume in the volume set.

To create a snapshot, Snapshot Manager for Data Center calls a Post REST API method with the required information and snapshot name. The API returns the details of the snapshot.

A snapshot created by Snapshot Manager for Data Center has the following naming convention:

NB<unique_21digit_number>

Snapshots created by Snapshot Manager for Data Center have the description: :vrtscp: <Parent Volume Set Name>.

Delete snapshot

To delete a snapshot set, Snapshot Manager for Data Center calls a REST API method with the required snapshot details. Snapshot Manager for Data Center deletes only those snapshots that it creates itself.

Restore snapshot

To restore a snapshot set, Snapshot Manager for Data Center calls a Post REST API method with the required snapshot details. If the base volume is in an attached state, it is detached and then restore is tried. After the restore, the volume is re-attached to the same host. With the RMC APIs you can restore a single snapshot from a snapshot set, you can restore any volume from a snapshot set.

Export snapshot

Snapshot Manager for Data Center supports the export of snapshots over the iSCSI and FC protocols. When a snapshot export operation is initiated, a new clone volume set is created using the snapshot set. Once this clone is created, then a host is attached to the same. It is recommended to do a SAN zoning between the host and array that is required to be attached to the snapshot.

Deport snapshot

When a snapshot deport operation is initiated, Snapshot Manager for Data Center deletes the export mapping created between the host and the clone volume set. The intermediate clone volume set is also deleted, once it is detached from the host.
