I'm running FreeBSD 2.1.5 from the Walnut Creek CDROM.
I just bought a used SCSI tape drive. I could only afford the
least costly:
Archive/Conner/Seagate 2150S
HH-Internal-SCSI Tape 150/300Mg, 1 New 6150 Tape Included.
According to the stickers it's the Archive.
I have only two weeks to decide if the drive is OK and the clock
began yesterday...
Naturally the first thing that I found is that the vendor from whom
I bought my system only included enough connectors on my SCSI cable
for the devices that I ordered so I had to scurry around to find a
cable.
Now I find that my system doesn't seem to be finding the tape drive
when it boots.
I couldn't find anything in the handbook or the faq about adding
a tape drive.
Any suggestions about where to look and what to look for will be
much appreciated.
The system is basically all SCSI. Disk and CDROM are working.
I can't see the jumpers for the disk-drive but according to the
2940 scsi utilities, it is SCSI ID 0.
The CDROM drive is jumpered for SCSI ID 1.
The tape drive came jumpered for SCSI ID 4 and I left it that way.
The 2940 scsi utilities (I guess it's actually the Adaptec scsi
utilities) see only the disk drive, the CDROM drive, and the host
adapter (SCSI ID 7).
The tape drive is not at the end of the cable and it has an empty
termination resistor socket above the SCSI connector.
Trying tar to see if it's really there anyway:
PC% tar tvf /dev/rst0
tar: can't open /dev/rst0 : Device not configured
PC%
Checking /dev:
PC% ls /dev/*st*
/dev/erst0 /dev/nrst0 /dev/rst0 /dev/rst0.ctl /dev/st0ctl.3
/dev/erst0.0 /dev/nrst0.0 /dev/rst0.0 /dev/sndstat /dev/stderr
/dev/erst0.1 /dev/nrst0.1 /dev/rst0.1 /dev/st0ctl.0 /dev/stdin
/dev/erst0.2 /dev/nrst0.2 /dev/rst0.2 /dev/st0ctl.1 /dev/stdout
/dev/erst0.3 /dev/nrst0.3 /dev/rst0.3 /dev/st0ctl.2
PC%
Of course some of those are unrelated files that happen to have
"st" in the filename.
All of the files listed in the st man-page FILES section seem to be
there.
Checking my kernel configuration file (eliminating obviously unrelated
"st"s as in "Filesystem":
^^
PC% grep st KERNEL.CRS
options "SCSI_DELAY=15" #Be pessimistic about Joe SCSI device
device st0
PC%
Just to be sure, I'll look at that section and list what I find
that looks relevant.
>From KERNEL.CRS:
controller ahc0
[...]
controller scbus0
[...]
device sd0
device st0
device cd0 #Only need one of these, the code dynamically grows
Do I need to be more specific in the kernel configuration file
than above? As mentioned, disk and CDROM are working.
[I'll append dmesg output at the end of this message. I apologize
for all of the "not found" messages in dmesg. I made only those
changes to my kernel configuration file that were needed earlier
and haven't had time to go back and clean it up by eliminating
stuff that I don't have. The "st0" line is as it came in the
GENERIC kernel configuration file.]
I suppose that I could re-install FreeBSD (2.1.5) to see if that
finds the tape drive but I really hate to do that if I can avoid
it.
Here's the output from dmesg:
