Zosi - I would presume that 3494 Category Code number 600 is the one you
       defined for your Private (storage pool) category tapes.
(Do 'Query LIBRary' to verify.)  Search back in your Activity Log to review
the history of that volume and how it got into that state, and what data
it may contain.  If appropriate, do a CHECKIn LIBVolume to return it to
storage pool usage.
