I've seen this happen when two disks or the SCSI controller and a single
disk are set to the same SCSI ID.  Since you seem to indicate that you have
one disk per chain, I would guess that they are (a) conflicting with their
SCSI controllers (the usual default on VAXes is for the controller to be
set to 6, but they are adjustable from the boot prom), or (b) you have a
controller or drive electronics failure (also possible, but less likely IMHO).

You'll have to dig through the FAQ or some other source for the exact
command to check and reset the controller ID (which is usually higher that
any other devices, giving it a higher (better) priority when it comes to
SCSI interrupt negotiations).  Try the HELP or SET commands (SET SCSI seems
to come to mind) for more information.

Hope this helps,
