Dell PowerVault MD 32XX/36XX Series Storage Arrays CLI Guide

Redistributing virtual disks returns the virtual disks to their preferred RAID controller module owners. The preferred RAID controller module ownership of a virtual disk or disk group is the RAID controller module of an active-active pair that is designated to own the virtual disks. The preferred owner for a virtual disk is initially designated when the virtual disk is created. If the preferred RAID controller module is being replaced or undergoing a firmware download, ownership of the virtual disks is automatically shifted to the second RAID controller module. The second RAID controller module becomes the current owner of the virtual disks. This change is considered to be a routine ownership change and is reported in the MEL. To redistribute virtual disks to their preferred RAID controller modules, run the following command:

reset storageArray virtualDiskDistribution

Under some host operating systems, you must reconfigure the multipath host driver. You might also need to make operating system modifications to recognize the new I/O path to the virtual disk.
