If the owner changes the real volser, he/she will not be able to link to the disk a second time :)

Why would anyone want to use CMS formatted volumes? That suggests that someone is going to have an mdisk that starts on real cyl 0 and allows the owner of the mdisk (volume) to change the real vol serial. There is simply no reason at all to allow that. Even if you say that real cyl 0 is going to be an mdisk owned by a $ALLOC$ type of userid, why would you want to format it using CMS. CP and MVS are real operating systems. Give them real operating system labels and VTOCs. Jim At 06:31 PM 2/8/2006, you wrote: > ... > > I presume that you have a reason to have an OS VTOC.
