Let me second the notion that this might be a scsi issue. Cabling is
possible.
Also, how many drives are on a single scsi chain? Is this something
that just started
out of the blue after a long period of no problem?
The randomness of this always complicates diagnosis. Examining log
file entries,
might show that it's less random than you think.
