RESYNCHRONIZATION
CLI EQUIVALENCE
createvvcopy –r <destvol>
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.
uint32 ModifySynchronization(
[In, REQ,
Values {“Detach”, “Fracture”, “Resync”, “Restore”,
“Prepare”, “Unprepare”, “Quiesce”, “Unquiesce”,
“Reset to Sync”, “Reset to Async”, “Start Copy”,
“Stop Copy”},
ValueMap {“2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”,
“10”, “11”, “12”, “13”}]
Uint16 Operation,
[Out]CIM_ConcreteJob ref Job,
[In, REQ] CIM_StorageSynchronized ref Synchronization);
 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.
