SMI-S METHOD
A physical copy can be resynchronized with the source volume by a CIM client using the
TPD_StorageConfigurationService.ModifySynchronization() method with the
Operation parameter set to Resync(4). A target volume that is in a Broken state (copy failed)
cannot be resync-ed.

• Operation: describes the type of modification to be made to the replica:
Detach: 'Forget' the synchronization between two storage objects. Start to treat the objects
independently. This performs the same function as promoting a physical copy.
◦
◦ Fracture: Suspend the synchronization between two storage objects using Sync or Async
replication. Not supported for local copy.
◦ Resync: Causes a snapshot to be restarted as a new PIT (Point-In-Time) image with a new
value assigned to WhenSynced. This performs the same function as resynchronizing a
physical copy.
◦ Restore: Copies a snapshot to the source element. This performs the same function as
promoting virtual copy.
◦ Prepare: Get the link ready for a Resync operation to take place. Not supported.
◦ Unprepare: Clear a prepared state if a Prepare is not to be followed by a Resync
operation. Not supported.
◦ Quiesce: Stops the copy engine for snapshots and the snapshot no longer consume space.
Not supported.
◦ Unquiesce: Take the link out of the quiesce state. Not supported.
◦ Reset to Sync: Changes the CopyType value of a mirror replica from “Async” to “Sync”.
Not supported.
◦ Reset to Async: Changes the CopyType value of a mirror replica from “Sync” to “Async”.
Not supported.
◦ Start Copy: Initiate a full background copy of the source to the UnSyncAssoc replica.
Replica enters a Frozen state when the copy operation is completed. This performs the
same function as issuing a createvvcopy again on an existing physical copy.
◦ Stop Copy: Stop the background copy previously started. This performs the same function
as halting a physical copy.
• Job: A Job is created as a side-effect of the execution of the method, and a reference to that
Job is returned through this parameter.
• Synchronization: The reference to the StorageSynchronized association describing the
storage source/replica relationship.
