Configuration: Disk Groups and Virtual Disks

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.
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 Virtual Disk Change Ownership/Preferred Path.
3 Select the appropriate RAID controller module slot and click Yes to 

confirm the selection. 

To remove the host to virtual disk mapping:

1 In the AMW, select the Mapping tab.
2 Select a virtual disk from the Defined Mappings pane.
3 Perform one of these actions:

• Select 

Mappings Remove.

• Right-click the virtual disk, and select 

Remove Mapping from the 

pop-up menu.

4 Click Yes to remove the mapping.
