CIM_Synchronized class

Indicates that two ManagedElements were aligned or made to be equivalent at the specified point in time. If the Boolean property SyncMaintained is true, then synchronization of the Elements is preserved. Both like and unlike objects can be synchronized. For example, two WatchDog timers can be aligned, or the contents of a LogicalFile can be synchronized with the contents of a StorageExtent.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

The CIM_Synchronized class has these types of members:

Properties

The CIM_Synchronized class has these properties.

CopyRecoveryMode
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

Describes whether the copy operation continues after a broken link is restored.

Automatic: copy operation resumes automatically.

Manual: CopyState is set to Suspended after the link is restored. It is required to issue the Resume operation to continue.

CopyState
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

CopyState describes the state of the association with respect to Replication activity. Values are:

Initialized: The link to enable replication is established and source/replica elements are associated, but the data flow has not started.

Unsynchronized: Not all the source element data has been copied to the target element.

Synchronized: For the Mirror, Snapshot, or Clone replication, the target represents a copy of the source.

Broken: The relationship is non-functional due to errors in the source, the target, the path between the two or space constraints.

Fractured: Target is split from the source.

Split: The target element was gracefully (or systematically) split from its source element -- consistency is guaranteed.

Inactive: Data flow has stopped, writes to source element will not be sent to target element.

Suspended: Data flow between the source and target elements has stopped. Writes to source element are held until the association is Resumed.

Failedover: Reads and writes to/from the target element. Source element is not reachable.

Prepared: Initialization is completed, the data flow has started, however, the data flow has not started.

Aborted: The copy operation is aborted with the Abort operation. Use the Resync Replica operation to restart the copy operation.

Skewed: The target has been modified and is no longer synchronized with the source element or the point-in-time view.

Mixed: Applies to the CopyState of GroupSynchronized. It indicates the StorageSynchronized associations of the elements in the groups have different CopyState values.

Partitioned: State of replication relationship can not be determined, for example, due to a connection problem.

Invalid: The array is unable to determine the state of the replication relationship, for example, after the connection is restored; however, either source or target elements have an unknown status.

FailedCopyStopsHostIO
Data type: boolean
Access type: Read-only
Qualifiers: Experimental

If true, the storage array tells host to stop sending data to source element if copying to a remote element fails.

Mode
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

Mode describes whether the target elements will be updated synchronously or asynchronously. If NULL, implementaton decides the mode.

Unknown (0)

Synchronous (2)

Asynchronous (3)

PercentSynced
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

Specifies the percent of the work completed to reach synchronization. Must be set to NULL if implementation is not capable of providing this information.

ProgressStatus
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

ProgressStatus describes the status of the association with respect to Replication activity. Values are: Completed: The request is completed. Data flow is idle.

Dormant: Indicates that the data flow is inactive suspended or quiesced.

Initializing: In the process of establishing source/replica association and the data flow has not started.

Preparing: preparation-in-progress.

Synchronizing: sync-in-progress.

Resyncing: resync-in-progess.

Restoring: restore-in-progress.

Fracturing: fracture-in-progress.

Splitting: split-in-progress.

Failing over: in the process of switching source and target.

Failing back: Undoing the result of failover.

Detaching: detach-in-progress.

Aborting: abort-in-progress.

Mixed: Applies to groups with element pairs with different statuses. Generally, the individual statuses need to be examined.Suspending: The copy operation is in the process of being suspended.

Requires fracture: The requested operation has completed, however, the synchronization relationship needs to be fractured before further copy operations can be issued.

Requires resync: The requested operation has completed, however, the synchronization relationship needs to be resynced before further copy operations can be issued.

Requires activate: The requested operation has completed, however, the synchronization relationship needs to be activated before further copy operations can be issued.

Pending: The flow of data has stopped momentarily due to limited bandwidth or busy system.

RequestedCopyState
Data type: uint16
Access type: Read-only
Qualifiers: Experimental, ModelCorrespondence ("CIM_Synchronized.CopyState")

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.

SyncedElement
Data type: CIM_ManagedElement
Access type: Read-only
Qualifiers: Key

SyncedElement represents another ManagedElement that is synchronized with the entity referenced as SystemElement.

SyncMaintained
Data type: boolean
Access type: Read-only

Boolean indicating whether synchronization is maintained.

SyncType
Data type: uint16
Access type: Read-only
Qualifiers: Experimental

SyncType describes the intended outcome of the replication.Values are:

Mirror: create and maintain a copy of the source.

Snapshot: create a PIT, virtual copy of the source.

Clone: create a PIT, full copy the source.
