Example 1 with SmisBlockResumeSnapshotJob

use of com.emc.storageos.volumecontroller.impl.smis.job.SmisBlockResumeSnapshotJob in project coprhd-controller by CoprHD.

the class VmaxSnapshotOperations method resumeSnapshot.

/**
 * Routine will call SMI-S ModifyReplicaSynchronization to resume a synchronization instance.
 * The operation is a counter-intuitive; it will terminate a RESTORE session between
 * target and source. This was the suggestion based on input from SMI-S team.
 * See OPT 443785.
 *
 * @param storage [in] - StorageSystem object representing the array
 * @param from [in] - Should be the snapshot object
 * @param blockObject [in] - Should be the volume object
 * @param syncObject [in] - A CIMObjectPath representing the SMI-S synchronization object tying
 *            from and blockObject together, along with other related consistency group members
 * @param taskCompleter [in] - TaskCompleter used for updating status of operation
 * @return true if the resume operation was successfully performed on the synchronization
 * @throws WBEMException
