Hi List, I have a question about what we recently experienced when dealing with Defined Capacity changes. Say I have a production LPAR with a defined capacity of 100 and a tech-only LPAR with 10. Management decides that we can afford an extra 2 MSU, temporarily. So I enter Change LPAR Controls and change the production LPAR's Defined Capacity to 102 and a tech-only LPAR to 8. At this point, I click the Change Running System button to apply the change.
A few days later, the tech-only LPAR was re-IPL'd using a custom group with a load profile. The IPL was performed by selecting Activate. We notice at this point that the tech-only LPAR's Defined Capacity was set to 10. We promptly changed it back to 8. Then, to test this situation again, I started with a baseline of production=100 and tech-only=5. I entered Change LPAR Controls again and changed the tech-only to 8 and again clicked on Change Running System. This time, when the IPL was performed via an activate, the LPAR came up with a defined capacity of 8. I've found some conflicting documentation on the Google: http://www-01.ibm.com/support/docview.wss?uid=tss1wp102437&aid=1 This page says that Change Running System changes are lost after a POR http://www-01.ibm.com/support/docview.wss?uid=isg209611e17c3b8d419852573f700645d4d&aid=1 This page says that it's lost after a reactivation of a partition It seems that PR/SM selects the highest Defined Capacity between the Running System and what's saved in the Activation profile for the LPAR. Can anyone shed some light as to how PR/SM actually works?
