To change a copy source or copy destination disk (change the LUN_V size or LUN_V number), first delete the source or replica volume, then change the disk configuration. After that, perform setup processing for the source or replica volume, and then setup processing for correcting or registering the copy set file.
These tasks must be performed before the configuration of the copy source or copy destination disk is changed. Otherwise, deletion of the copy set or of the source or replica volumes may not be possible after the device configuration is changed.
In the Hyper-V Guest OS, check the copy status using the VSSHP status lookup command (stxvquery). If any copying is in progress, or if QuickOPC is in the tracking state, use the VSSHP "backup control command (stxvcopy)" or the VSSHP "batch stop command (stxvstopall)" to stop copying or the tracking process.
If QuickOPC is in the tracking state, the copy source or copy destination disk cannot be changed. If you want to change the copy destination for a transaction volume during QuickOPC backup, the tracking process must be stopped.
Delete the source or replica volume on the device to be reconfigured. Refer to "9.8.2 Deleting Source and Replica Volumes" for more information.
If there are changes in the configuration of source or replica disk partitions, initialize the disk. Refer to "8.2.6.4 Initializing a disk" for details.
Reconfigure the device.
Add the device information. Refer to "7.4.4 Fetching device information on a Managed Server" for information about this operation.
Perform "8.2.3.2.6 Creating a copy set file" and "8.2.3.2.7 Registering copy sets as a batch" to change the copy set information.
On the Hyper-V host, perform "8.2.3.2.8 Checking and saving the copy set registration contents".
Set up the source and replica volumes.
