Good thing I put some history of my problem in ;-)

it was very strange indeed ... I guess it was a "restore" message, but why I
got it, who knows.

Cool. I will try that.

DOH ... my grepping was flawed ... I was looking for the whole string on a
single line ....

I should have also said I got a few of these in my syslog:
(sa0:ahc0:0:2:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command to clear this state.
Tonight, I did "mt rewind" on a tape I was fooling with yesterday and got the
following in messages:
(sa0:ahc0:0:2:0): SCB 0x8 - timed out while idle, LASTPHASE == 0x1, SEQADDR == 0x8
(sa0:ahc0:0:2:0): Queuing a BDR SCB
(sa0:ahc0:0:2:0): Bus Device Reset Message Sent
(sa0:ahc0:0:2:0): no longer in timeout, status =
anything of consequence?

OK. I will redo the quirk like above and include CAMDEBUG (I was actually just
reading cam(4) coincidentally :) and see if things improve. I will also do the
setoetmodel that you suggested.

*definitely*
Thanks for the response! It is quite late tonight so I'll get back to debugging
this problem tomorrow. If it is a matter of the quirk being re-written slightly
as you did above and things work, I'll send-pr with the trivial patch.
I am curious to know if anybody else reading -scsi owns or knows of somebody
who owns one of these TapeStor 8000 drives with ROM 4.11 in it? If so, are they
experiencing the same wierdness? Thanks,
