The part of this that concerns me is the status bits BOT (beginning of tape) and DR_OPEN (door open) being on at the same time. On my 8505, DR_OPEN means that there is no tape in the drive, and if there is no tape, how can it be at the beginning?
I would suggest a proper shutdown for the server, including switching off the power. While the server is off, switch off all the external SCSI devices. Then turn the externals on one at a time, followed by the server.
If it's still confused about the tape drive, my guess is that it's a hardware/firmware problem in the tape drive.

Hi,
I have a strange problem with my backup system. Everything worked the other
day - until I rebooted the server. The system consists of Redhat 5.2,
amanda-2.4.1p1, Exabyte 8700.
Here is the output of mt status:
[bin@mail sbin]$ mt status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0

However, when I run Amcheck:
[bin@mail sbin]$ ./amcheck seascape
Amanda Tape Server Host Check
-----------------------------
/var/amanda/spool: 6608043 KB disk space available, that's plenty.
insert tape into slot 11 and press return
It appears not to detect a tape in the drive (any tape i put in there). All
the tapes "are" labeled correctly (recently been used). I don't know if I
might have a hardware problem or an amanda configuration problem.
The backup system wasn't configured by me -- it was already setup when I
took over the position. Any suggestions appreciated.
Shane
