Of course that was on a z9-109, but I'm sure I did the same thing on our z990s when we had them. I just tested changing storage on one of my z9-109 sandbox LPARs and changing the number of reserved CPs without doing a deactivate prior to an activate, and both changes were reflected on the running system when I IPLed. Interesting that there is a warning message on the HMC that indicates that "additional actions may be required to activate these changes. Reference the PR/SM Planning Guide." after updating the profile, but the PR/SM planning guide document this clearly as you indicated. The only thing that is clear is that the behavior of ACTIVATE has changed on at least a z9-109. If someone who has a z990 still and a sandbox LPAR wants to test out of curiosity, I'd be interested in the results. However, it never hurts to do the deactivate and probably takes less than 10 seconds, so I guess better safe than sorry.
