Termination, that was the problem.. Seems when the other machine
connected to the array is off there is no termination, which stands to
reasons but why no auto termination?

Once properly terminated all problems are solved. Except if the other
machine ever goes down I get scsi bus problems which will pretty much
kill the other machine.

doh.
