OK... Got to be carefull here... For i5 OS partitions at 5.4 and below, 
disk is allocated by the Disk Controller. ie All Disks on controller 'A' 
will be in the same i5 OS Partition. Depending on the card in use etc 
there may not be anymore slots available for this partition. So at this 
point  we need to know the system model, expansion model(s) and a 
rackcfg of this partition.
