dss full DUMP CPVOLUME for OS MiniDisks like z/VSE

ADRDSSU dump is not possible for DASDs with multiple OS MiniDisks. Our customers have separated some DASDs into many smaller z/VM MiniDisks for use by his z/VSE. But same problem could occur for other products under z/VM, that create OS-Disks. Problem rises if the OS MiniDisk starts on cylinder 0 of the DASD.
- When I use DUMP TRACKS with the CPVOLUME keyword, dss says "UNABLE TO OPEN VOLUME", because the volume is not VM-formatted, it contains an OS- VTOC from VSE.
- When I omit the CPVOLUME keyword, I cannot dump the full volume in one step, because the dump looks into the VTOC and sees only the first cylinders of the first VM-MiniDisk.
On some volumes our customer has created many MiniDisks and I don't know the size and location.

Another ADRDSSU DUMP problem, which could be solved at the same time, is that I need to know which type of disk I have to dump, before I start the dump job, because the usage of the CPVOLUME parameter is depending on the type of the volume. But I don't know if the volume contains CP-volumes or OS-disks, when I put the dump-JCL together. So currently I have to check cylinder 0 of hundreds of disks, before I can choose the correct dump parameters.

Therefore a parameter would be nice to make a full-volume dump disregarding the type of volume, if there's an OS-disk on cylinder 0 or not.
