130 Configuration: Disk Groups and Virtual Disks3 Perform one of these actions:• Select Mappings Remove.• Right-click the virtual disk, and select Remove Mapping from thepop-up menu.4 Click Yes to remove the mapping.Changing the RAID Controller Module Ownership of a Disk GroupYou can change the RAID controller module ownership of a a disk group.You can change the RAID controller module ownership of a standard virtualdisk or a snapshot repository virtual disk. You cannot directly change theRAID controller module ownership of a snapshot virtual disk because thesnapshot virtual disk inherits the RAID controller module owner of itsassociated source virtual disk. Changing the RAID controller moduleownership of a virtual disk changes the preferred RAID controller moduleownership of the virtual disk.During a virtual disk copy, the same RAID controller module must own boththe source virtual disk and the target virtual disk. Sometimes both virtualdisks do not have the same preferred RAID controller module when thevirtual disk copy starts. Therefore, the ownership of the target virtual disk isautomatically transferred to the preferred RAID controller module of thesource virtual disk. When the virtual disk copy is completed or is stopped,ownership of the target virtual disk is restored to its preferred RAID controllermodule. If ownership of the source virtual disk is changed during the virtualdisk copy, ownership of the target virtual disk is also changed. Under certainoperating system environments, it might be necessary to reconfigure themulti-path driver before an I/O path can be used.To change the RAID controller module ownership of a disk group:1 In the AMW, select the Logical tab and select a disk group.2 Select Disk Group Change Ownership/Preferred Path.3 Select the appropriate RAID controller module slot and click Yes toconfirm the selection.CAUTION: Possible loss of data access– Changing ownership at the disk grouplevel causes every virtual disk in that disk group to transfer to the other RAIDcontroller module and use the new I/O path. If you do not want to set every virtualdisk to the new path, change ownership at the virtual disk level instead.
