The best way to check for attached drives is to stop the boot (top left 
function key (usually stop) and a at the same time) and use the prom 
commands, in this case probe-scsi. My guess is that you have duplicated 
scsi addresses, IIRC the internal drives are 0 and 3. Again IIRC the 
internal drives of the SS5 take their addresses from the connector which is 
why you can't set them.

The scsi bus is terminated internally but not externally and hence you will 
need to terminate the bus. Many drives have manual or automatic termination.
