Discover assets

CloudPoint discovers all the SAN volumes (virtual disks) that are part of storage pools that are created on the InfiniBox storage array. The plug-in sends a request to the array to return a list of all the volumes that have the type set as PRIMARY. Such volumes are considered as base volumes and appear as disk assets.

To discover snapshot objects, the plug-in sends a request to the array to return a list of all the volumes that have the type set as SNAPSHOT and the depth attribute set as 1. Such volumes are considered as snapshots.

InfiniBox arrays support creating a snapshot of a snapshot. The depth attribute identifies the snapshot type. A snapshot depth value greater than 1 indicates that it is a snapshot of an existing snapshot. CloudPoint does not support discovery and operations on snapshot volumes that have a depth value other than 1.

Create snapshot

CloudPoint takes a snapshot of all the SAN volumes that are part of a storage pool. When a snapshot is created, CloudPoint plug-in uses InfiniSDK to send a create_snapshot method request on the selected volume and passes a snapshot name as an argument in that request.

The InifiniBox array creates a snapshot volume, sets the type as SNAPSHOT and the depth attribute value as 1, and returns that information to CloudPoint.

Delete snapshot

When a snapshot is deleted, CloudPoint plug-in sends a delete_snapshot method request on the parent volume that is associated with the snapshot and passes the snapshot volume name as an argument in that request. The InfiniBox array deletes the specified snapshot associated with the parent volume.

Restore snapshot

When a snapshot restore operation is triggered, CloudPoint first gets details about the parent volume that is associated with the snapshot that is being restored. CloudPoint plug-in then sends the restore_snapshot method request on the parent volume and passes the selected snapshot as an argument in that request.

The array uses the selected snapshot to perform the restore on the parent volume. All the data in the parent volume is overwritten by the data in the snapshot volume.

Export snapshot

When a snapshot export operation is triggered, CloudPoint searches for the target host based on the world wide name (WWN) or the iSCSI Qualified Name (IQN) specified in the export request. After the host is identified, CloudPoint plug-in sends a map_volume method request on the target host and passes the selected snapshot ID as an argument in that request.

The InfiniBox array returns a LUN ID as a response to the restore request. CloudPoint stores the LUN ID and the target host ID mapping information internally in the CloudPoint database. The export operation also creates a new virtual asset of type disk:snapshot:export and that is saved in the CloudPoint database.

Deport snapshot

When a snapshot deport operation is triggered, CloudPoint first gets the target host ID from the database. The CloudPoint plug-in then sends a unmap_volume method request on the target host and passes the selected snapshot ID as an argument in that request. The InfiniBox array removes the snapshot volume mapping from the specified target host.
