| Hi Kevin
Jumper J51 should be enabled (across two left pins) at all times
there is a srm console param pka0_soft_term which controls
termination. i think it should be OFF but i not sure if already
OFF turn it ON. could be scsi length problem also 3 meters max?
note 570 in this notes file is another thread on these scsi issues
there talking about active terminator only, im not sure what that
means. notes 570, 728, 802

to get to srm console mode to check or change paramater
push in the Halt Button on ocp leaved it depressed
hit the reset button
console should stop at srm >>>
>>>show pka0_soft_term
i think in your config this should be set to OFF
>>>set pka0_soft_term off <<this changes it to off
>>>set pka0_soft_term ? <<this will show all valid settings
release halt button
reset system
should boot to arc/wnt
the other thing going on is scsi length?
can only be 3 meters max or less total length
there's only about 1 meter or less out the back of system
depending on internal storage box setup?

As stated Jumper J51 should be enabled (across two left pins) at all
times. The pka0_soft_term does nothing to the on-board termination for
the embedded SCSI controller.
The Main logic board auto senses what cables are plugged in and
terminates accordingly. If only the narrow cable is plugged in then
the termination is active on the MLB and the other end of the narrow
cable.
The question is do you have ACTIVE termination at after the external
tape unit. The termination must be active. (not passive)
Also, is the entire storage shelf configured for use. If so you even
have less than a meter, actually barely even 1/2 meter.
