Dell MD3200, MD3220 owner manual 128

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.

1Do 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.

2To 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.
