Jack, just a couple of things. the 2780's require V5R3. I believe that you could use the 2757's if you must stay at V5R2. They are about the same card. And the other thing is that the RAID striping will be "updated", the 2780/2757's have a different way of striping the disk. It will happen automagicially or you can stop raid, swap the card and restart raid. a little dangerous as your system is unprotected, but of course you will have a couple of backups ready if needed. Good luck. ---------------------------- Bryan Dietz Aktion Associates midrange-l-bounces@xxxxxxxxxxxx wrote on 03/07/2005 10:21:10 PM: > To All, > > Have any of you folks had experience with upgrading the I/O controllers on a > V5R2 830 4x from 2778's to 2780's.
