Do you save the indexes to tape at all (even if it's via a separate
job)?  If so, 'nsrck -L7' can find it.  If you have access to the
appropriate volume, it should work.  But 'scanner -i' is always
available as a fallback.

Yes.  Why don't you save indexes to tape in some manner?  If you have a
problem with the server, you're not going to want to use scanner to
recreate all the indexes on your volumes.

We can't guess.  All you know is that it's not in the database.  You
might want to examine it with scanner to determine if it should be
re-introduced to the database, or if you want to label it as an
available tape for backups.
