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"},

"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.
◦
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.
