AFAIK, SMS managing tapes is much simpler than dasd. The only thing SMS really does is to assign a DC, SC, MC and SG to a tape in the ACS routines and these constructs are passed to the tape library, which does its thing with them. We don't have uncatalogued tapes, but I am quite sure they can be.
What is the reason that you must go to SMS managed tape?
