It is perfectly fine to combine a system-level defined capacity limit with a group limit - though it won't be required with the numbers you use. You may want to verify in the RMF MON III CPC report that the LPAR is member of the capacity group. A member that does not meet the requirements (such as initial capping unchecked, using shared processors, z/OS R8 or above) would not be joined to the group.

No idea why. I think I'll change the individual LPAR caps anyway. It's duplicitous in any event.

LPAR Group Controls
Greetings again, I have two LPARs that I'm trying to group softcap to 76 MSU's. I set the defined capacity in each to 76 and made them both members of the DEFAULT group and set that group capacity to 76. I expect this to allow resources to shift between both LPARs as needed. What I'm observing is the test LPAR looks like it's hard-capped based on its weighting and is not getting the resources the production LPAR doesn't need below the 76 MSU softcap. I still need to ensure more preference is given to the production LPAR, so I believe weighting is appropriate. But I also need the unused resources to be available to the test LPAR.
