You definitely do not want to try to run any job that examines the
tape. First, I don't know if what you are asking is possible --
possibly on the more modern drives (LTO-6 or greater), but in any case,
any time you move the tape, you wear it, so don't make the tape drive
move any more than necessary to backup/restore your data.
Best regards,

"it's possible to know the raw capacity of each tape and how much data
has been stored on each tape"
Unfortunately the author doesn't elaborate on that.
It would be useful to have an advanced warning when one or more
parameters determining free raw space reaches a dangerous value (say
under 10% left).
Even if the percentage cannot be accurately relied on it's still
better then nothing.
I looked into "btape" command but couldn't find the answer.
Has anybody had any success reliably determining raw space left on LTO
tapes?
