The final word on the zIIP thing is going to be our capacity person. If that person is okay with the situation then I'm okay with it. From where I sit I don't want any more overhead for zIIP management then needed. We only have 3 zIIP on the box. 10 of the lpars get 1 zIIP and the 11th lpar gets 2 zIIP. That 11th lpar is an important lpar. Yes we have the weights set for the zIIP that the tech lpars are bottom on the list.
If you are suggesting that we config offline the 2nd zIIP before BOOST is done, my answer would I don't know what would happen. That would be a question for IBM to answer. That is why we are looking at testing BOOST=SPEED to see how that reacts. That's why we all have the tech lpars in our environments to try things out before we roll to production. Thanks..

What's the down side to having that zIIP online to that lpar? Is some other work losing out because (presumably lower importance) "tech" work is being done on the zIIP? > Just daydreaming here, but it would be nice if there was a time limit > you could set for how long BOOST was active (unless I missed > something).
