Unfortunately, I'm reasonably sure that the machine Adam's using has a RZ23 on
sd2, and a RZ24 on scsi id 3, which is where the scsi code's going bonkers.

So it's not that there's a problem talking to rz23 drives; that machine's
_booted_ from a rz23.  

On the other hand, the bit about "scsi target -1 DNE" (does not exist, I
assume) looks like a fandango on core symptom to me, no?
