Yes it will be a 13th device, but it will only exist for the duration of
the shuffle. You need to delete and re-add one device, but you can't do
that while it's still defined in a jukebox. You need the extra device as a
placeholder since your jukebox needs to always contain 12 devices. So the
dummy device gets defined and added in to the jukebox in place of the real
device. You will then delete the real device and re-add it as an NDMP
device. It can then go back in to the jukebox definition in place of the
dummy. It's a bit like the extra variable you always need when you're
coding a sort program in order to swap two values.
I hope I'm making some sense here....
The device can be anything, just a file device is fine, perhaps make a
directory, say /tmp/dummydisk, and call it that. You're never going to use
it in anger or label/mount any volumes on it.
