Supported NetBackup operations on IBM Storwize array
You can perform the following Snapshot Manager for Data Center operations supported on the IBM Storwize SAN models:
Table: Snapshot Manager for Data Center operations on the IBM Storwize 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 a volume asset, created 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 a snapshot. |
Create snapshot | To create a snapshot, Snapshot Manager for Data Center initiates a Post Rest API method with the required snapshot details. The API returns with the snapshot details. 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 Storwize array, when the snapshot operation is initiated, the snapshot of that entire consistency group is taken. |
Delete 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. |
Restore snapshot | To restore a volume snapshot or consistency group snapshot, Snapshot Manager for Data Center calls a PUT REST API method. 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 is 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 that is required to be attached to the snapshot. |
Deport snapshot | To delete a volume or consistency group snapshot, Snapshot Manager for Data Center calls the REST API. |
