I'm attempting to restrict DFU to inquiry only for specific users. I renamed STRDFU in QSYS to something else, then wrote my own STRDFU command & CLP. The CLP restricts various users as necessary. All 'qualified' users still get full blown DFU, the others get inquiry only. The problem is that I get an MCH4429 error (storage overflow). Does anyone know of a way to get around the message?
