I'm trying, still to get a working Amanda setup. This is on my home
system in advance of setting it up for a client next week :-). It's
FC4, and the drive is a Quantum DLT 7000, which I think is a 35/70Gb
model. It's old.
I think the old DLT drive (haven't used it for a few years, but it
worked the last time I had it plugged in) may be dead. Here's what I
notice:
1) The "use cleaning tape" light was on. I plugged in a cleaning tape,
and the light went out; but then when I plugged i na real tape, the
drive pretty quickly turned the "use cleaning light" back on again.
This has happened a few times--the cleaning tape seems to work, but
then as soon as I put in a real tape, the drive wants cleaning again.
2) mt fails with I/O errors:
[matt@matt ~]$ sudo mt erase
Password:
/dev/tape: Input/output error
3) tar fails similarly:
[matt@matt ~]$ sudo tar -cvf /dev/st0 * .*
amy/
bin/
bin/addressbook.csv
bin/palm-ldif2csv
tar: /dev/st0: Cannot write: Input/output error
tar: Error is not recoverable: exiting now
(in both cases I can tell that it's trying the right device, because
the drive makes a horrible grinding noise, and the tape spins a little
bit, before the errors come up).
4) getting errors in /var/log/messages:
Dec 19 18:36:35 matt kernel: <<vendor>> ASC=0x80 ASCQ=0x1ASC=0x80 ASCQ=0x1
Dec 19 18:36:35 matt kernel: Info fld=0x1

Dec 19 18:36:46 matt kernel: Info fld=0x1
Dec 19 18:36:46 matt kernel: st0: Error on write filemark.
I've googled those errors, and I can't find anything really pointing
me to an answer. I've checked termination (this is an Adaptec
2940U2W), and the card is set to "automatic" on both interfaces, which
almost always works, in my experience.
For good measure, here are some related lines from dmesg:

Is there something dumb I've failed to do? Let me know!
Thanks a lot,
