Configuration: Disk Groups and Virtual Disks 145
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.
1
To change:
a
The RAID controller module ownership of a virtual disk—Go to
step 2.
b
The RAID controller module ownership of a disk group—Go to step 3.
2
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
Virtual Disk
Change
Ownership/Preferred Path
.
Alternatively, you can right-click the virtual disk and select
Change
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.
3
To change the RAID controller module ownership of a disk group, perform
these steps:
a
Select the
Logical
tab.
b
Select the disk group.
c
Select
