Anderson) Newsgroups: comp.sys.next Subject: Adding a scsi tape drive Message-ID: Date: 26 Nov 90 14:29:53 GMT Sender: news@umd5.umd.edu Distribution: comp Organization: Dept. of Cognitive Science, The Johns Hopkins University Lines: 32 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.....
