Writes to source element are held until the association is resumed. 10 - 'Failedover': Reads and writes to/from the target element. Source element is not reachable. 11 - 'Prepared': Initialization completed and the copy operation started; however, the data flow has not started. 12 - 'Aborted': The copy operation is aborted with the Abort operation. Use the Resync Replica operation to restart the copy operation. 13 - 'Skewed': The target has been modified and is no longer synchronized with the source element or the point-in-time view. 14 - 'Mixed': Applies to the CopyState of GroupSynchronized. It indicates the StorageSynchronized associations of the elements in the groups have different CopyState values.'
'CopyType describes the Replication Policy. Values are: 2 - 'Async': create and maintain an asynchronous copy of the source. 3 - 'Sync': create and maintain a synchronized copy of the source. 4 - 'UnSyncAssoc': create an unsynchronized copy and maintain an association to the source. 5 - 'UnSyncUnAssoc': create an unsynchronized copy with a temporary association that is deleted upon completion of the copy operation.'
'Specifies the percent of the work completed to reach synchronization. Must be set to NULL if implementation is not capable of providing this information.'
PercentSynced property is in 1 class (MSFT_VirtualDiskToVirtualDisk) of ROOT\Microsoft\Windows\Storage\ms_409 and in 5 namespaces
'ProgressStatus describes the status of the association with respect to Replication activity. Values are: 2 - 'Completed': The request is completed. Copy operation is idle. 3 - 'Dormant': Indicates that the copy operation is inactive suspended or quiesced. 4 - 'Initializing': In the process of establishing source/replica association and the copy operation has not started. 5 - 'Preparing': preparation-in-progress. 6 - 'Synchronizing': sync-in-progress. 7 - 'Resyncing': resync-in-progress. 8 - 'Restoring': restore-in-progress. 9 - 'Fracturing': fracture-in-progress. 10 - 'Splitting': split-in-progress. 11 - 'Failing over': in the process of switching source and target. 12 - 'Failing back': Undoing the result of failover. 13 - 'Detaching': detach-in-progress. 14 - 'Aborting': abort-in-progress. 15 - 'Mixed': Applies to groups with element pairs with different statuses. Generally, the individual statuses need to be examined. 16 - 'Suspending': The copy operation is in the process of being suspended. 17 - 'Requires fracture': The requested operation has completed, however, the synchronization relationship needs to be fractured before further copy operations can be issued. 18 - 'Requires resync': The requested operation has completed, however, the synchronization relationship needs to be resynced before further copy operations can be issued. 19 - 'Requires activate': The requested operation has completed, however, the synchronization relationship needs to be activated before further copy operations can be issued. 20 - 'Pending': The flow of data has stopped momentarily due to limited bandwidth or busy system.'
'ReplicaType provides information on how the Replica is being maintained. Values are: 2 - 'Full Copy': This indicates that a full copy of the source object is (or will be) generated . 3 - 'Before Delta': This indicates that the source object will be maintained as a delta data from the replica. 4 - 'After Delta': This indicates that the replica will be maintained as delta data from the source object. 5 - 'Log': This indicates that the replica object is being maintained as a log of changes to the source. 0 - 'Not Specified': The method of maintaining the copy is not specified.'
'RequestedCopyState is an integer enumeration that indicates the last requested or desired state for the association. The actual state of the association is represented by CopyState. Note that when CopyState reaches the requested state, this property will be set to 'Not Applicable.'
RequestedCopyState property is in 1 class (MSFT_VirtualDiskToVirtualDisk) of ROOT\Microsoft\Windows\Storage\ms_409 and in 5 namespaces
'SyncState describes the state of the association with respect to Replication activity. Values are: 2 - 'Initialized': The link to enable replication is established and source/replica elements are associated, but the Copy engine has not started. 3 - 'PrepareInProgress': Preparation for Replication is in progress and the Copy engine has started. 4 - 'Prepared': All necessary preparation has completed. 5 - 'ResyncInProgress': Synchronization or Resynchronization is in progress. This may be the initial 'copy' or subsequent changes being copied. 6 - 'Synchronized': An Async or Sync replication is currently synchronized. When this value is set, SyncMaintained will be true. 7 - 'FractureInProgress': An operation to fracture an Async or Sync replication is in progress. 8 - 'QuiesceInProgress': A quiesce operation is in progress. 9 - 'Quiesced': The replication has been quiesced and is ready for a change. 10 - 'RestoreInProgress': An operation is in progress to copy the Synced object to the System object. 11 - 'Idle': The 'normal' state for an UnSyncAssoc replica. 12 - 'Broken': The relationship is non-functional due to errors in the source, the target, the path between the two or space constraints. 13 - 'Fractured': An Async or Sync replication is fractured. 14 - 'Frozen': All blocks copied from source to an UnSyncAssoc replica and the copy engine is stopped. 15 - 'CopyInProgress': A deferred background copy operation is in progress to copy the source to the replica target for an UnSyncAssoc association.
