Ok, here is what I have tried finally. Trying to get amtapetype to work.
[root@localhost ~]# mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN
[root@localhost ~]# mt -f /dev/nst0 offline
/dev/nst0: Input/output error
[root@localhost ~]# mt -f /dev/nst0 load
/dev/nst0: Input/output error
[root@localhost ~]# mt -f /dev/st0 status

DR_OPEN IM_REP_EN
[root@localhost ~]# mt -f /dev/st0 load
/dev/st0: Input/output error
Here's what the log says
Sep 8 13:30:50 localhost kernel: st0: Error with sense data: <6>st0:
Current: sense key: Not Ready
Sep 8 13:30:50 localhost kernel: Additional sense: Medium not present
Any ideas?
Thanks alot
Nick

You figured wrong.
mtx works on the robotic changer mechanism,
st0 is a tape drive inside your changer.
mt is for manipulating tape drives.
I have two tape drives, and standalone Ultrium and a DDS 3 changer.
mtx -f /dev/st<whatever> does nothing useful on my system.
Doesn't give an error, just hangs.

Does anything do anything with your tapedrive?
Can you tar to it? tar from it? dd to or from it? cat to or from it?

bacula may be a fine product.
But unless you can access your tapedrive with some basic commands
no backup product is going to do diddly.
