Having a drive not spin up or show up is a definite problem related to
drive health if nothing else changed.
When you swap the drives are you changing the mechanical orientation of
the drives i.e. is one drive array mounted horizontal and the other
vertical for instance? That can cause drives with high hours not to spin
up as readily.

Hi Neal--
Thank you very much for your reply. I'll give ASM and the re-generate
options a try. Just to make sure, does the "regenerate" option endanger
any
of the media that I have on the array?
There is one other factor that I forgot to mention... We have two sets
of
drives that we regularly swap in the mediadock. About 1 out of 3 times
, when I put in the set of drives that is generating the error, only
seven
of the eight drives come up in the manage disks window. After shutting
everything off and reseating the drives, all eight will show up. Think
this
is related?
