Very Computer

I can't seem to get my scsi tape drive to write to tapes.
I am running RedHat 6.2 with all the updates, and I have rebuilt the
kernel to include scsi support for as well as atapi/scsi for the cd
burner.  The scsi card is a Adaptec AHA-2910c and the tape drive is an
Onstream 50gb ADR.

When I first installed the card kudzu found it and but configured it as
a Adaptec AIC-7850 SCSI, I'm not sure if this is causing my problem.
When ever I try to right to the drive I get and input/output error.  If
I try to use KDat to mount a tape it says its unable to rewind the
drive.
I can't seem to find any information on this type of problem, can
someone help me?

Here are the error messages I get

[computer]# mt -f /dev/nst0 rewind

When I try to mount the tape the following errors are reported in

Thanks

I do not know your hardware, but ...

how is the load of the machine at this time

did you try reboot?

maybe there is a error with the tape.

did you try erase the tape
it sometimes helps:

mtst  -f /dev/nst0 erase

sounds not too wrong

Everything boots fine, it recognizes the 2 scsi hosts and the onstream
tape as a scsi
mt -f /dev/nst0 erase gives an input/output error

The tape isn't write protected, is it?  My Seagate tape
drive chokes when the little red tab on the Travan tapes is
set to "Locked".  Obviously I can't write to locked tapes,
but I can't even *read* them.  Any mt command gives an
input/output error.  (Took me a half hour to figure that out
when I first tried to restore from a locked tape.  Checked
drivers, software, everything but that stupid little tab!)

Nope not write protected
