There was some discussion about multitape-changer recently. Use some of
the list archives to see if there is relevant information for you...

I don't think this is how multitape-changer works. I never actually used
it, but I think it simulates a one-drive autochanger with a number of
slots equal to the number of drives you have.

Sure, Bacula doesn't create device nodes for you.

So the autochanger setup didn't work. What does btapes test command tell
you?

So the multitape-changer setup is not correct. See that thread I
mentioned for more information.
Or hope to find someone who actually uses that... (or pay me :-)
seriously, I didn't get the impression that the suggested multichanger
script is easy to use).
