.. _CIM-StorageSynchronized: CIM_StorageSynchronized ----------------------- Class reference =============== Subclass of :ref:`CIM_Synchronized ` Indicates that two Storage objects were replicated at the specified point in time. If the CopyType property is set to 'Sync' (=3), then synchronization of the Storage objects is preserved. Key properties ^^^^^^^^^^^^^^ | :ref:`SystemElement ` | :ref:`SyncedElement ` Local properties ^^^^^^^^^^^^^^^^ .. _CIM-StorageSynchronized-CopyPriority: ``uint16`` **CopyPriority** CopyPriority allows the priority of background copy engine I/O to be managed relative to host I/O operations during a sequential background copy operation. Values are: Low: copy engine I/O lower priority than host I/O. Same: copy engine I/O has the same priority as host I/O. High: copy engine I/O has higher priority than host I/O. Urgent: copy operation to be performed as soon as possible, regardless of the host I/O requests. ======== =============== ValueMap Values ======== =============== 0 Not Managed 1 Low 2 Same 3 High 4 Urgent .. DMTF Reserved 0x8000.. Vendor Specific ======== =============== .. _CIM-StorageSynchronized-ReplicaType: ``uint16`` **ReplicaType** ReplicaType provides information on how the Replica is being maintained. Values are: Full Copy: This indicates that a full copy of the source object is (or will be) generated . Before Delta: This indicates that the source object will be maintained as a delta data from the replica. After Delta: This indicates that the replica will be maintained as delta data from the source object. Log: This indicates that the replica object is being maintained as a log of changes to the source. Not Specified: The method of maintaining the copy is not specified. ======== =============== ValueMap Values ======== =============== 0 Not Specified 2 Full Copy 3 Before Delta 4 After Delta 5 Log .. DMTF Reserved 0x8000.. Vendor Specific ======== =============== .. _CIM-StorageSynchronized-SystemElement: :ref:`CIM_ManagedElement ` **SystemElement** SystemElement represents the Storage that is the source of the replication. .. _CIM-StorageSynchronized-UndiscoveredElement: ``uint16`` **UndiscoveredElement** This property specifies whether the source, the target, or both elements involved in a copy operation are undiscovered. An element is considered undiscovered if its object model is not known to the service performing the copy operation. The values are: SystemElement: The source element. SyncedElement: The target element. Both: Both the source and the target elements. If both the source and the target elements are discovered, the value of this property shall be NULL. ======== =============== ValueMap Values ======== =============== 2 SystemElement 3 SyncedElement 4 Both .. DMTF Reserved 0x8000.. Vendor Specific ======== =============== .. _CIM-StorageSynchronized-CopyType: ``uint16`` **CopyType** CopyType describes the Replication Policy. Values are: Async: create and maintain an asynchronous copy of the source. Sync: create and maintain a synchronized copy of the source. UnSyncAssoc: create an unsynchronized copy and maintain an association to the source. UnSyncUnAssoc: create an unsynchronized copy with a temporary association that is deleted upon completion of the copy operation. ======== =============== ValueMap Values ======== =============== 2 Async 3 Sync 4 UnSyncAssoc 5 UnSyncUnAssoc .. DMTF Reserved 0x8000.. Vendor Specific ======== =============== .. _CIM-StorageSynchronized-CopyMethodology: ``uint16`` **CopyMethodology** CopyMethodology specifies what copy methodology the service uses to create and/or maintain the target element. Values are: Not Specified: The method of maintaining the copy is not specified. Full Copy: This indicates that a full copy of the source object is (or will be) generated . Incremental-Copy: Only changed data from source element is copied to target element. Differential-Copy: Only the new writes to source element are copied to the target element. Copy-On-Write: Affected data is copied on the first write to the source or to the target elements. Copy-On-Access: Affected data is copied on the first access to the source element. Delta-Update: Difference based replication where after the initial copy, only updates to source are copied to target. Snap-And-Clone: The service creates a snapshot of the source element first, then uses the the snapshot as the source of the copy operation to the target element. ======== ====================== ValueMap Values ======== ====================== 0 Not Specified 1 Other 2 Implementation decides 3 Full Copy 4 Incremental-Copy 5 Differential-Copy 6 Copy-On-Write 7 Copy-On-Access 8 Delta-Update 9 Snap-And-Clone ..

Vendor Specific ======== ====================== .. _CIM-StorageSynchronized-SyncState: ``uint16`` **SyncState** SyncState 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 Copy engine has not started. PrepareInProgress: Preparation for Replication is in progress and the Copy engine has started. Prepared: All necessary preparation has completed. ResyncInProgress: Synchronization or Resynchronization is in progress. This may be the initial 'copy' or subsequent changes being copied. Synchronized: An Async or Sync replication is currently synchronized. When this value is set, SyncMaintained will be true. FractureInProgress: An operation to fracture an Async or Sync replication is in progress. Fractured: An Async or Sync replication is fractured. QuiesceInProgress: A quiesce operation is in progress. Quiesced: The replication has been quiesced and is ready for a change. RestoreInProgress: An operation is in progress to copy the Synced object to the System object. Idle: The 'normal' state for an UnSyncAssoc replica. Frozen: All blocks copied from source to an UnSyncAssoc replica and the copy engine is stopped. CopyInProgress: A deferred background copy operation is in progress to copy the source to the replica target for an UnSyncAssoc association. Broken: The relationship is non-functional due to errors in the source, the target, the path between the two or space constraints. ======== ==================== ValueMap Values ======== ==================== 2 Initialized 3 PrepareInProgress 4 Prepared 5 ResyncInProgress 6 Synchronized 7 Fracture In Progress 8 QuiesceInProgress 9 Quiesced 10 Restore In Progresss 11 Idle 12 Broken 13 Fractured 14 Frozen 15 Copy In Progress ..

SyncedElement: The target element. Both: Both the source and the target elements.are read only to the host. ======== =============== ValueMap Values ======== =============== 2 SystemElement 3 SyncedElement 4 Both ..
