Assuming that you are planning to flash all of your production DASD at one
time, you can do something like this:
PRODUCTION LPAR BACKUP LPAR
--------------- ---------------
| | | |
| PRODUCTION | | PRODUCTION |
| DASD | | DASD |
| | | |
| OFFLINE=NO | | not included|
| in IODF | | in IODF |
| | | |
--------------- ---------------
--------------- ---------------
| | | |
| BACKUP | | BACKUP |
| DASD | | DASD |
| | | |
| OFFLINE=YES | | OFFLINE=NO |
| in IODF | | in IODF |
| | | |
--------------- ---------------
(You may have to cut this out and paste it into WORD with a COURIER NEW
font to see this correctly.)
The production LPAR would FLASH the OFFLINE=NO DASD to the OFFLINE=YES
DASD. You need both sets of addresses genned somewhere to do the
flashcopy from MVS. (It can also be done from the DS/8000 HMC; you really
don't want to go there!)
This is just one method; there are others that will work just as well.
