You can create a target storage volume that is a replica
of an existing storage volume.
A new target storage volume is a replica of the source
storage volume.
- Select an IBMTSSVC_StorageVolume instance as the source
volume for the preferred FlashCopy relationship.
- Retrieve the IBMTSSVC_StorageConfigurationService instance
that is associated with the IBMTSSVC_Cluster instance to which the
selected IBMTSSVC_StorageVolume instances belong.
- Start the IBMTSSVC_StorageConfigurationService.CreateReplica() method with the following
parameter specifications:
- Set SourceElement to the reference (CIMObjectPath) of the source IBMTSSVC_StorageVolume.
- Optionally, set TargetSettingGoal to the reference (CIMObjectPath) of the target storage volume
setting IBMTSSVC_StorageVolumeSetting.
The CIM client can create a thinly provisioned target volume replica or a thin-provisioned
compressed target volume replica by setting the relevant reference of IBMTSSVC_StorageVolumeSetting.
If TargetSettingGoal is null, a target storage volume with the same properties as the source
storage volume is created.
- Optionally, set ElementName to the name of the synchronization.
- Optionally, set TargetPool to the reference (CIMObjectPath) of the target storage pool
IBMTSSVC_ConcreteStoragePool from which the target storage volume is created.
- Optionally, set CopyType to control whether FlashCopy mappings are automatically deleted:
- Set CopyType to 5 to automatically delete the FlashCopy mapping after the
background copy is complete. This setting sets AutoDelete to true.
- Set CopyType to 4 if you do not want to automatically delete FlashCopy
mappings.
The target storage volume is returned to the CIM client
by TargetElement, which is now connected to the
source IBMTSSVC_StorageVolume through the IBMTSSVC_LocalStorageSynchronized
association.
