Hi Jerry,


Yes, if you have enough room on the partition you can create another 
tape image catalog.  Use the DUPTAP command to duplicate them all onto 
one volume if they fit. The maximum virtual tape size is 1TB.


    Create the new tape image catalog
    Create a virtual tape big enough to hold all 23 source volumes
    Initialize the target volume
    Use DUPTAP for example:  DUPTAP FROMDEV(TAPxx) TODEV(TAPyy) 
FROMSEQNBR(*FIRST *LAST) TOSEQNBR(*FROMSEQ) FROMENDOPT(*UNLOAD)

The DUPTAP command will autoload all 23 volumes and duplicate them to 
the one target volume.


Kind Regards,

Tony Janisch
