I have a TEAC 155 Mbyte scsi tape drive which I used to use with my
macintosh. When I tried to connect it to my NeXT cube, however, I had
problems:
(1) The TEAC is unterminated, at scsi address 3 on the bus between the
cpu and a (terminated) disk at sci address 4. There's also the
internal disk at sci address 0. When I power the system on, if the
tape is turned on I get persistent scsi failures until I turn off
power to the tape drive. Once I do this, the boot sequence proceeds
normally and I can turn power back on to the tape drive.
(2) mt -f /dev/rst0 (or 1) fails with the message that there is no
such device. /dev/(n)rst{0,1} exist. How do I tell the kernel the scsi
address of the drive (assuming the supplied st driver in OS1.0 will
support it)?
I tried, naturally, to RTFM, but the online documentation I have has a
number of major holes: in particular, a lot of sections like "adding a
tape drive to the system" are marked as not available on line. As far
as I can tell, there's no off-line documentation either, or else
Businessland didn't give it to me (they claim there's nothing but the
User's Guide plus a thin system administration guide that only
discusses network setup). In general, how do I find more complete
documentation on system administration and maintenance? Perhaps the
online manuals with 2.0 will be better, but then I can't install that
(even when I get it) until I can back up my present files, and I can't
do that until I can get the tape working.....
