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. Removing Host-to-Virtual Disk Mapping 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. 120 Configuration: Disk Groups and Virtual Disks
