Well....looks like I've been busted! There are a couple of caveats.
Yes, CP supports it, but here are a few restrictions :
- CMS can only access a disk of 32,767 cylinders or less
- A (virtual) minidisk that is greater than 32,767 cylinders is not eligible for minidisk cache regardless of what is marked in the directory or conf file.
- A real disk track will not be brought into the minidisk cache if it exists above real cylinder 32,767 with recent APAR VM64115.
