the class VmaxSnapshotOperations method createGroupSnapshots.

/**
 * Should implement create of a snapshot 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 snaps. Upon the successful
 * device creation, the post operations will take place, which will include the
 * creation of the target group and the group snapshot operation.
 *
 * @param storage [required] - StorageSystem object representing the array
 * @param snapshotList [required] - BlockSnapshot URI list representing the previously created
 *            snap for the volume
 * @param createInactive whether the snapshot needs to to be created with sync_active=true/false
 * @param readOnly - Indicates if the snapshot should be read only.
 * @param taskCompleter - TaskCompleter object used for the updating operation status.
 * @throws DeviceControllerException
