I'm in the middle of relocating our entire computer room so I'll be
brief :) I have a bunch of LTO1s in a L80 hooked to a O3k so that's
essentially what you have. I'll be moving this to a Debian system soon
and in my testings I could drive the library and tape drives with mtx
and mt no problem except for the hardware compression bit on the
drive: after much mucking around with stinit I couldn't disable it but
seems the for LTO that's not a problem. Still looking for a way to
disable it though.

To your problem: what does 'mt status' says?

Here's what I got on a Debian system running 2.6.x

~# mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (41010000):
 BOT ONLINE IM_REP_EN
