The TS7700 VTS uses categories, not in private or scratchpools. Each virtual tape has a category.
The OS (z/OS, z/VM, z/TPF) issues a 'mount from category xxxx' when it needs a scratch tape. When a tape is written, the OS changes the category to 'its' private category. When the tapemanagement system scratches a tape, it is changed to 'its' scratch category. These categories are defined in DEVUPxx and can be different per system or Sysplex or OS. This way, each OS can have its own set of scratch and private tapes. e.g. our Prod Sysplex has: MEDIA1=0011, MEDIA2=0012, ERROR=001E, PRIVATE=001F, Out Test Sysplex has: MEDIA1=0111, MEDIA2=0112, ERROR=011E, PRIVATE=011F, Does this answer your question?
