128 Configuration: Disk Groups and Virtual Disks
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 may be necessary to reconfigure the multi-
path driver before an I/O path can be used.

Do you want to change the RAID controller module ownership of a virtual
disk or a disk group?
• Change the RAID controller module ownership of a virtual disk – Go
to step 2.
• Change the RAID controller module ownership of a disk group – Go
to step 3.

To change the RAID controller module ownership of a virtual disk,
perform these steps:
a
Select the
Logical
tab.
b
Select the virtual disk.
c
Select

Ownership/Preferred Path
.
Alternatively, you can right-click the virtual disk and select

Ownership/Preferred Path
from the pop-up menu.
d
Select the RAID controller module.
CAUTION: Possible loss of data access – If you do not use a multi-path driver,
shut down any host applications that are currently using the virtual disk. This
action prevents application errors when the I/O path changes.
e
Click
Yes
.
The ownership of the virtual disk is changed. I/O to the virtual disk is now
directed through this I/O path. You are finished with this procedure.
NOTE: The virtual disk may not use the new I/O path until the multi-path driver
reconfigures and recognizes the new path. This action usually takes less than 5
minutes.
