Private                                 Status value reported in
                                        'Query LIBVolume'.
                                        A tape just checked in a Private will
                                        have a null Last Use because there was
                                        no last use.
                                        A tape will be forced to Private status
                                        when there is an I/O failure on a
                                        Scratch volume, as *SM sets it to
                                        Private to keep from thrashing on the
                                        scratch mount.  Look in the Activity Log
                                        for the message "8778W Scratch vol
                                        ... changed to Private Status to prevent
                                        re-access".
                                        If in 'Query LIBVol', Last Use is blank,
                                        expect that the volume was last used for
                                        a DUMPDB operation if the volume is a
                                        long-term resident of the library.
