Changing the RAID Controller Module Ownership of a Virtual Disk or a Disk Group

You can change the RAID controller module ownership of a virtual disk or a disk group.

You can change the RAID controller module ownership of a standard virtual disk or a snapshot repository virtual disk. You cannot directly change the RAID controller module ownership of a snapshot virtual disk because the snapshot virtual disk inherits the RAID controller module owner of its associated source virtual disk. Changing the RAID controller module ownership of a virtual disk changes the preferred RAID controller module ownership of the virtual disk.

During a virtual disk copy, the same RAID controller module must own both the source virtual disk and the target virtual disk. Sometimes both virtual disks do not have the same preferred RAID controller module when the virtual disk copy starts. Therefore, the ownership of the target virtual disk is automatically transferred to the preferred RAID controller module of the source virtual disk. When the virtual disk copy is completed or is stopped, ownership of the target virtual disk is restored to its preferred RAID controller module. If ownership of the source virtual disk is changed during the virtual disk copy, ownership of the target virtual disk is also changed. Under certain operating system environments, it might be necessary to reconfigure the multi-path driver before an I/O path can be used.
