The simplest way to 'freeze operations' in an LPAR is the MVS QUIESCE command, which puts the system into a restartable wait state. I was in a shop a long time ago that routinely used QUIESCE while switching a communications front-end controller from one device to another. The pause lasted only seconds and mostly worked. Years later I tried it in another system, and VTAM got so hosed that only IPL finally straightened it out. So try it--but don't be shocked at the results.
I'm much more concerned about the tenor of your two posts on CPU utilization. In your other post, you ask what symptoms indicate the need for upgrade. Mr. Bright, read your two posts aloud to yourself. You are a veritable poster child for processor upgrade. The theme is CPU desperation. You need help. Now. . . .
