Supported Snapshot Manager Operation on IBM SAN Volume Controller array
You can perform the following Snapshot Manager for Data Center operations supported on the IBM SVC models:
Table: Snapshot Manager for Data Center operations on the IBM SVC array
Snapshot Manager for Data Center operations | Description |
|---|---|
Discover assets | Snapshot Manager for Data Center discovers all the volumes, consistency groups, volume snapshots, and consistency group snapshot present on the array. Snapshot Manager for Data Center discovers only the snapshots created by NetBackup. Note: The snapshot volume is also considered as the volume asset while creating a snapshot. Snapshot Manager for Data Center discovers the FlashCopy mappings present on the array, where the target volume of mapping is considered as a snapshot. |
Create snapshot | To create a snapshot, Snapshot Manager for Data Center initiates the Rest API method with the required snapshot details. The API returns with the snapshot details. The snapshot is then taken for the volume selected in the NetBackup policy. A snapshot is created with the following naming convention: NB<unique_21digit_number> When Snapshot Manager for Data Center calls the REST API for a volume, the following process takes place:
For creating consistency group snapshots, here is the process:
You can specify the volumes that are included in a source volume in a consistency group in the NetBackup policy. In the IBM SVC array, when the snapshot operation is initiated, the snapshot of that entire consistency group is taken. |
Delete snapshot | To delete a volume or consistency group snapshot, Snapshot Manager for Data Center initiates a DELETE Rest API call with the required snapshot details. |
Restore snapshot | To restore a volume snapshot or consistency group snapshot, Snapshot Manager for Data Center calls a PUT REST API method call with the required snapshot details. When a restore is initiated, a new FlashCopy mapping is created where the snapshot volume acts as the source volume and the source volume acts as the target volume. Then the mapping is started as a restore operation. Note: The mappings created during the restore operation are deleted automatically after the restore is complete. |
Export snapshot | Snapshot Manager for Data Center supports export snapshot over the iSCSI and FC protocols. When a snapshot export operation is initiated, the snapshot volume gets attached to the host on the array. Snapshot Manager for Data Center uses the same process for consistency group snapshots. SAN zoning must be done between the host and the array, which is required to attach with 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 volume(s) created during the export operation. |
