Snapshot Manager for Data Center operation | Description |
|---|---|
Discover assets | Snapshot Manager for Data Center discovers all the HPE RMC volume sets and their snapshot sets. |
Create snapshot | HPE RMC allows to take snapshot of the entire volume set at once. The result of a create snapshot operation is a snapshot set that contains snapshot 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.

Snapshots created by Snapshot Manager for Data Center have the description:
|
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 attached state, it is detached and then restore is tried. After the restore, 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 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 with the snapshot. Note: NetBackup does not discover the cloned volume set created in the export operation. |
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. |
