where, virtualDiskName is the identifier for the virtual disk.
NOTE: Initializing a thin virtual disk may take an extremely long time.
Redistributing Virtual Disks
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.
CAUTION: Ensure that a multipath driver is installed, or the virtual disks are not accessible.
To redistribute virtual disks to their preferred RAID controller modules, run the following command:
reset storageArray virtualDiskDistribution
NOTE: You cannot run this command if all virtual disks are currently owned by their preferred RAID controller
module or if the storage array does not have defined virtual disks.
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.
