I picked up an old Qualstar model 1054 9 track scsi tape drive for reading old data tapes.
It is missing the Users Guide, document #500100, that I need to correctly set the dip
switches so that I can use it on my old RS6000. I've found a reference to the guide
(http://www.qualstar.com/pan003.pdf) telling me what to do but not how. As it is, when I
try to read a tape it rewinds and unloads.

the AIX /dev directory has both rewinding and nonrewinding devices in
it. It will possibly do that when you connect to the device with a
command. Also you may get a SCSI reset doing that.
I know there were a lot of issues when we wrote tape code to access
tapes at Ultimate for the Pick system we sold that had to be worked
around. You might try it on an Adaptec on a PC with Linux before going
to AIX so you are only fighting one problem at a time till it is functional.
I assume you can see it properly configured with smit, etc before trying
to do anything with it as well. I don't know for sure about non IBM
1/2" tapes how they would show up, but you should be sure that you see a
good report in the device report in smit first.
