Hi Peter, Thank you for your input. It is a bit strange reading your statement
" To be picky, RACF never "interferes". RACF only answers a question asked of it. " as I so frequently said something akin to that so many times over the years. Should RACF be called on what would be a second extent on a DASD file? On a catalogued tape dataset there is no problem. Does MVS consider the second tape volume as an open on an existing dataset instead of an extent of an open one? That would count as a resource not protected.
