Maintaining a Storage Array
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.
