Example 1 with SmisVnxCreateCGCloneJob

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

the class VnxCloneOperations method createGroupClone.

/**
 * Should implement create of a clone from a source volume that is part of a
 * consistency group.
 *
 * Implementation note: In this method we will kick of the asynchronous creation
 * of the target devices required for the CG clones. Upon the successful
 * device creation, the post operations will take place, which will include the
 * creation of the target group and the group clone operation.
 *
 * @param storage [required] - StorageSystem object representing the array
 * @param clonetList [required] - clone URI list
 * @param createInactive whether the clone needs to to be created with sync_active=true/false
 * @param taskCompleter - TaskCompleter object used for the updating operation status.
 * @throws DeviceControllerException
