I've not used chg-manual, always had a changer. But I suspect that "slots"
are only appropriate for hardware that actually has storage for unloaded
tapes. Chg-manual might still be appropriate IF the loading and unloading
must be done manually rather than under software control. But that is not
your case, you only have the one slot, so don't lie to amanda and tell it
you have 99 slots (or whatever).
So I'd guess you still need to configure your chg-manual script. But, as
I noted, I've not used chg-manual. Maybe someone else will chime in.
Also, you need more than 2 tapes in rotation, time to amlabel a few more.
I'd suggest that after you modify/configure your chg-manual script
you wipeout any of the datafiles chg-manual has already created.
I.e. there is no sense for chg-manual having a datafile indicating
tape 2 is in slot 2 if there is only 1 slot configured.
