Is it a right device? For mtx you need to use scsi generic device.
Could you show your lsscsi -g output command, please?

I'm worried about your "Hardware End of Medium = No", "Fast Forward
Space File = No" and "TWO EOF = yes" parameters. Did you test your
configuration with btape? What was the result? This is my Device
resource for IBM LTO-4 drive:
Device {
Name = Drive-0
Drive Index = 0
Media Type = LTO-4-IBM
Archive Device =
"/dev/tape/by-path/pci-0000:04:00.0-fc-0x2002000e111354e4:0x0000000000000000-nst"
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Maximum File Size = 8GB
Spool Directory = /var/spool/bacula
Maximum Spool Size = 800G
Maximum Job Spool Size = 128G
# Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
# If you have smartctl, enable this, it has more info than tapeinfo
# Alert Command = "sh -c 'smartctl -H -l error %c'"
}
It is working great for a few years now.

Autochanger definition is not working. I suspect it is a problem with
wrong autochanger device. YMMV.

Well, if your autochanger is not working (see above comment) then "No
medium found" is a right error for that. Did you verified what st
(/dev/st0, /dev/st1, ... etc.) device correspond to what drive index
in your configuration?

Could you show your manual test procedure and output?
For production setup I use a permanent device name provided by udev,
not /dev/st* or /dev/sg*. It saved me from a lot of trouble.
I fount you are using a lot of tape drives in you library, so I
recommend to verify what device correspond to what drive index in your
configuration. it is not usual that /dev/st0 has drive index = 5.
