Re: problem with scsi device (please help)

ok ok.. not all at once, please.. hehehehe

well.. I'm sorry to post again.. but as this is quite a problem for us
and I'd be grateful if somebody could give some support.

As I've seen no answer here, this morning I posted to -scsi as well..
and got no answers either..

so.. that's why I ask again.. and I'll also add some more info by
saying that last week
I installed another OS on that same machine.. just to
make sure it's not a hardware problem.. and it worked
without a problem.. went back to FreeBSD and the problem
is again there..

The server and the tape drive are younger than 1 year old
and the tapes are of good quality.

I'd be grateful if somebody could look into these logs
and tell me what's the problem... Please ask me if you
want more details.

Thank you.
