PR/SM can use additional engines
lowering the logical to physical ratio, but MVS only builds enough control

This may have been improved with recent releases of z/OS but this was
certainly an issue in the past.

IBM assures us that their stuff will work. Since we have the two engines in

an IPL or Activate. My question is in two parts.

It was true as Al and Ted wrote, but no longer true with z/OS 1.10.
Don't you still have to have the CP's RSVD in the LPAR profile?
That is a hardware issue rather than a software one.
