Normally I will use a backup disk to make copies of our system disk:  $255$DUA0:  and our Cluster disk $255$DUA1:.

• mount/for $255$DUA700:                                                                         (This is a backup disk)
• backup/image/ignore=interlock/log     $255$DUA0:     $255$DUA700:     (Makes identical copy of disk)

--This will make a backup copy of our system disk

To swap $255$DUA0 with $255$DUA700: (from the table above you can see that D0 (DUA0) is on M2 (Mirr 2)  (show mirr)

ALL SYSTEMS MUST BE SHUTDOWN  (SHUTDOWN MCC/MCCDEV AND MCCA2)

• On HSJ011 you would type    show m2

HSJ011> sho m2

• DUA700: is M8 Partition 2

1. On HSJ011
   1. del d700                                 (This deletes the name only - data is fine)
   2. del d0
   3. add unit d0 m8 part=2            (This assigns the new disk number to the disk) -Swapping disk names.
   4. add unit d700 m2 part=1
