FWIW back in the day (miss those days) when I put approx 100+ sun4 machines
out for a client (mix of IPX/IPC/SS5/SS10/SS20) in the wild with various disk
& tape configs I recall always having to check the scsi IDbs. it seemed like
every install required checking and making sure.
And yes sunos4 was fixed IDs unless you recompiled
Tape ID4 (?I think it was or was it 5)
Hope that helps
