Which of them? Certainly, I can imagine that BACKUP LOG WITH TRUNCATE_ONLY
is not permitted when you have mirroring. Then again, why would you
want to truncate the log? Just back it up to remove the active portion.

It may still be that you cannot shrink a log when you have mirroring
active. In such case, you will have to make the choice of smashing the
mirror to be able to shrink the log, or remember the old proverb "disk
is cheap".
