Re: Disk swap on Model 600 with v4r2

[Larry Bolhuis <midrange@xxxxxxxxxxxx>]

How many drives do you have now and are they protected?

Best way to accomplish this is to copy the data. If you have room for 4 
more drives then swap the raid card in, start RAID on the new drives, 
copy the LS drive to one of the new drives. Move that drive into the LS 
position (bottom left) and IPL to that drive. Add the other 3 8GB drives 
to the system, remove the remaining 4GB drives from the system. You are 
done.

Only issue with this is if something goes 'thunk' once the copy is 
complete the old LS drive is of little use. It will still IPL to DST but 
won't know of the rest of your 4GB drives. You need to complete the 
migration. If you choose the tape method (SAVE 21/RESTORE 21) or Save 
Storage / Restore Storage then the old drives can be placed back in and 
will run just fine. Note that SAVE 21/RESTORE 21 will cause all your 
spooled files to go away *POOF* - just sayin....

By the way if you need parts for this migration let me know off list. I 
have many pieces and parts of that vintage in the FrankenLab, most 
likely everything you could need.
