Hello Kern, hello list,
good news!
This autochanger works perfectly (with bacula 1.38.9), see the attached file
btape.ok:
Kern, you can add it to working autochangers :-)

This is what Rocco Diez from "www.Computacenter.de" got from Quantum Germany:
"""
Hallo Herr Diez,
hiermit bestätigen wir die Zertifizierung für folgende Umgebung:
- Superloader 3 mit DLT-S4
- Gentoo Linux
- BackupSoftware Bacula 1.38.9

Because of this statement we bought the device from "Computacenter" an we will
switch from testing to production very soon.

We should be in file 3. I am at file 3. This is

Now the important part, I am going to attempt
to append to the tape.

Done appending, there should be no I/O errors
Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is
correct!
The above Bacula scan should have output
identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===
If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple
Jobs to
the tape.
=== Write, backup, and re-read test ===
I'm going to write three records and an EOF
then backup over the EOF and re-read the last
record.
Bacula does this after writing the last block
on the
tape to verify that the block was written
correctly.
This is not an *essential* feature ...

btape: btape.c:735

I'm going to write five files then test forward

Ah, I see you have an autochanger configured.
To test the autochanger you must have a blank
tape
that I can write on in Slot 1.
Do you wish to continue with the Autochanger
test? (y/n): y
=== Autochanger test ===
3301 Issuing autochanger "loaded" command.
Slot 5 loaded. I am going to unload it.
3302 Issuing autochanger "unload 5 0" command.

3303 Issuing autochanger "load 1 0" command.
3303 Autochanger "load 1 0" status is OK.
