Configuration: Disk Groups and Virtual Disks 135
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 res tored to it s preferre d RAID cont roller
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.
To change the ownership of the virtual disk to the connected controller:
1
In the AMW, select the
Logical
tab and select a virtual disk.
2
Select

Removing Host-to-Virtual Disk Mapping
To remove the host to virtual disk mapping:
1
In the AMW, select the
Mapping
tab.

Select a virtual disk from the

Perform one of these actions:
• Select

Changing the RAID Controller Module Ownership of a Disk Group
You can change the RAID controller module ownership of 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
