I find this interesting - the Quantum drive apparently does not grok
I had this exact drive on my Amiga for a long time. I never got
it at multiple LUNs. I then moved it to my Sun3/260, and it showed
up at multiple LUNs. A Quantum Lightning 730 also shows up at multiple
At the time I suspected that there was a glitch in the Sun3 SCSI driver.
I still do, because when the drive shows up at multiple LUNs, for some of
them I get an "illegal request". Or the geometry shows zero surfaces.
Or it doesn't show up at all LUNs. It seems to depend on which device I
boot from, although I have not nailed this dependency down.
Right now I am reworking the Sun3 SCSI driver, and I will be paying
attention to this problem. The Sparc esp driver apparently does the same
- Is it normal for a drive that doesn't understand LUNs to either
not respond to all probes, or to generate illegal request errors
for LUNs other than 0?
- How 'come this drive behaved itself on the Amiga, both under NetBSD
and AmigaOS, both of which, as far as I know, support LUNs?
