So it's right where you started? :-)
I guess you'll have to track the slot numbers yourself, as the library
simply doesn't do that for I/O-slots. (Which slots or magazines are
used for im/export can probably be configured, but I assume that you
want them as import/export slots so your operators can easily swap tapes.)
Actually, all the information you need is already in the catalog,
you've just got to modify mtx-changer to look the slot numbers up in
the catalog, and when doing the listing, you need to ensure the
I/O-slots are considered.
I'm planning something similar for a customer who probably needs to
use all the slots they have soon, but they are not there yet...
Cheers,
Arno
