Example 1 with SnapshotSessionUnlinkTargetsParam

use of com.emc.storageos.model.block.SnapshotSessionUnlinkTargetsParam in project coprhd-controller by CoprHD.

the class BlockSnapshotService method deactivateSnapshot.

/**
 * Deactivate volume snapshot, will result in permanent deletion of the requested snapshot from the storage system it was created on
 * and will move the snapshot to a "marked-for-delete" state after the deletion happens on the array side.
 * It will be deleted by the garbage collector on a subsequent iteration
 * If this snapshot was created from a volume that is part of a consistency group,
 * then all the related snapshots will be deactivated, as well.
 *
 * If "?type=VIPR_ONLY" is added to the path, it will delete snapshot only from ViPR data base and leaves the snapshot on storage array
 * as it is.
 * Possible value for attribute type : FULL, VIPR_ONLY
 * FULL : Deletes the snapshot permanently on array and ViPR data base.
 * VIPR_ONLY : Deletes the snapshot only from ViPR data base and leaves the snapshot on array as it is.
 *
 * @prereq none
 * @param id the URN of a ViPR snapshot
 * @param type the type of deletion {@link DefaultValue} FULL
 * @brief Delete snapshot
 * @return Snapshot information
