Sorry, I have no script and never have been in a situation like yours.
But tar is 'tape archiver' and it knows
-M for multi volume archive
-F run script at end of each tape (implies -M)
I'd use -F to call a script that
- unmounts the current tape
- mounts the next one
- either by 'mtx next' + some end of slots logic
- mtx load SLOT
- if it has been the last tape in the changer prompts for a new set of
tapes
- else exits for tar to continue
