Creating a new FlashCopy relationship between storage volumes

The IBMTSSVC_StorageConfigurationService class provides the methods for establishing a FlashCopy relationship between two IBMTSSVC_StorageVolume instances that are the same size and belong to the same IBMTSSVC_Cluster instance.

1. Select an IBMTSSVC_StorageVolume instance as the source volume for the preferredFlashCopy relationship.
2. Select a valid IBMTSSVC_StorageVolume as a target.

   Make sure that the source IBMTSSVC_StorageVolume and target IBMTSSVC_StorageVolume instances belong to the same IBMTSSVC_Cluster instance.

3. Retrieve the IBMTSSVC_StorageConfigurationService instance that is associated with the IBMTSSVC_Cluster instance to which the selected IBMTSSVC_StorageVolume instances belong.
4. Invoke the IBMTSSVC_StorageConfigurationService.AttachReplica() method with the following parameter specifications:
   1. Set SourceElement to the reference (CIMObjectPath) of the source IBMTSSVC_StorageVolume.
   2. Set TargetElement to the reference (CIMObjectPath) of the target IBMTSSVC_StorageVolume.
   3. Optionally set ElementName to the name of the synchronization.
   4. Optionally set BackgroundCopyRate to the preferred priority of the background copy rate (0 - 100).
   5. Optionally specify Set to add the newly created FlashCopySynchronization to the set. If you specify a null value, the newly created FlashCopySynchronization will not be a member of a synchronized set.
   6. Optionally set CopyType to 5. This sets AutoDelete to true, which automatically deletes the FlashCopy mapping after the background copy is complete.
   7. If you do not want to automatically delete FlashCopy mappings, Set CopyType to 4.
