IMPORTANT:
     Before doing an IPL on either LPAR or both, make sure you know what volumes are on each LPAR and what the duplicate Volsers are. You should go here,
display the volumes and print out the displays so you have hardcopy at hand when you IPL.

     As you IPL, you may need to reply r 00,CONT when requested or r 00,xxx' where xxx is the address to be put OFFLINE.

For example:
   Address 522 has volser R04CAT for the Prod LPAR.
   Address 581 has volser R04CAT for the Test LPAR.
When IPL of Prod LPAR finds the duplication and asks which to put offline, you would enter r 00,581.
When IPL of Test LPAR finds the duplication and asks which to put offline, you would enter r 00,522.
     The same would be done for other duplicate volsers as necessary.
