         - Extend, Migrate and Expand commands will fail if the controller
           cache is bad or the cache battery is less than 75%. These
           commands will work on controllers that are designed to support
           volume expansion by using disk drives for backing up expand data
           stripe. This is in the absence of battery backed memory on the
           controller.

         - RAID units that have spare disks (RAID 1, RAID 5 and so on)
           cannot be migrated to RAID 0 or JBOD units.

         - Multiple capacity disks can be used by specifying the "/SIZE"
           qualifier. The maximum value of size specified with the "/SIZE"
           qualifier should be the size available on the disk with the
           lowest capacity.
