Removing Host-To-Virtual Disk Mapping; Changing The Raid Controller Module Ownership Of A Disk Group - Dell POWERVAULT MD3620I Owner's Manual

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 may 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.
