Supported CloudPoint operations on HPE storage arrays
CloudPoint supports the following operations on assets managed by HPE RMC:
Table: CloudPoint operations on assets managed by HPE RMC
CloudPoint operation | Description |
|---|---|
Discover assets | CloudPoint discovers all the volumes that are created on the array. If a volume is part of a multi-volume volume set, CloudPoint scans the volume set and extracts the individual volume information and then creates a list of all the unique volumes that are part of the volume set. For snapshots, CloudPoint scans all the snapshot sets and links each snapshot to its originating parent volume. |
Create snapshot | CloudPoint takes snapshots of all the volumes on the array. When CloudPoint takes a snapshot, it internally triggers a copy-on-write (COW) snapshot of the entire volume. If a volume is part of a multi-volume volume set, CloudPoint takes a snapshot of the entire volume set and creates a snapshot set. The snapshot set contains snapshots of all the volumes that are part of that volume set. However, CloudPoint associates that snapshot set only with the volume that was selected for the snapshot operation. Even if the volume set contains additional volumes, the snapshot set is associated only with the volume that was selected. For example, consider a volume set that contains three volumes, |
Delete snapshot | CloudPoint deletes the snapshot or the snapshot set (if parent volume is part of a volume set). You can use CloudPoint to delete only those snapshots that are created using CloudPoint. If your RMC environment includes other snapshots, then CloudPoint can discover those snapshots, but the delete operation is not allowed for those snapshots. |
Restore snapshot | When you restore a snapshot, CloudPoint only restores the particular snapshot corresponding to the selected volume. The snapshot set is a COW snapshot that can contain other snapshots belonging to the additional volumes in the volume set. However, CloudPoint only restores the snapshot for the selected volume. The other snapshots are not used during the restore operation. Ensure that the parent volume is unmounted from the target host before initiating a snapshot restore. |
Export snapshot | When a snapshot export operation is triggered, CloudPoint creates a new volume from the snapshot and then attaches the new volume to the target host. If the selected snapshot is a snapshot set, then while creating a new volume, CloudPoint creates a new volume set from the snapshot set. Even if the new volume set contains multiple volumes, CloudPoint attaches only the volume that corresponds to the snapshot that was selected for the export. The other volumes are not used in the export operation. The export operation is supported using the following protocols:
|
Deport snapshot | When a snapshot deport operation is triggered, CloudPoint detaches the volume from the target host and then deletes that volume. If the volume is part of a multi-volume volume set, then the entire volume set is detached and deleted from the host. |
Note:
For a snapshot of a volume set, use name patterns that are used to form the snapshot volume name. Refer to VV Name Patterns in the HPE 3PAR Command Line Interface Reference available from the HPE Storage Information Library.
Consider the following when you configure the HPE EMC plug-in:
When you delete snapshots using CloudPoint, only the snapshots that are managed by CloudPoint are available for deletion. You cannot use NetBackup to delete snapshots that are not created using CloudPoint.
NetBackup operations are supported only on disks and volumes. Even if the volumes are grouped as a volume set, CloudPoint discovers and presents the volume set in the form of the individual volumes that are part of the volume set.
If you create a snapshot of a volume that belongs to a multi-volume volume set, CloudPoint creates a snapshot set that includes snapshots of all the volumes in that volume set. The snapshot operation therefore results in the creation of additional snapshots and those are not tracked by CloudPoint.
If you want to use CloudPoint to protect volume sets, Veritas recommends that you configure a single volume in the volume set.
