You should use the Q ACTLOG command with a begintime and begindate just
before a bunch of tapes were marked unavailable to see more information
about why this is happening. Though you are searching for a "needle in a
hay stack" you may be able to narrow it down with the SEARCH option on
the Q ACTLOG command. For instance, search on the volume name of a tape
that you know got marked unavailable during that time period. You could
also search on "UNAVAILABLE". The error messages giving the reasons are
in the ACTLOG, though finding them may take some searching.
