Changing The Raid Controller Module Ownership Of A Virtual Disk Or A Disk Group - Dell PowerVault MD3220 Owner's Manual

Changing the RAID Controller Module Ownership of a Virtual Disk or a
Disk Group
You can change the RAID controller module ownership of a virtual disk or a
disk group.
You can change the RAID controller module ownership of a standard virtual
disk or a snapshot repository virtual disk. You cannot directly change the
RAID controller module ownership of a snapshot virtual disk because the
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.
