The cbu is turned on via the HMC (I think). When you're done, you turn it off and the machine goes back to normal state. We've done this a few times and production VM stays up, doesn't hick-up or anything. Same thing for when we turn it off. That's how it works for us. YMMV Steve

Therefore we will activate the cbu record and upgrade the machine from model 2098-a01 to a z02 with 1 IFL. After the test how is the machine downgraded to a a01. Will it be done automatically or must it be done again with perform model conversion? Does anybody have experiences with this scenario and can give me any hints how the capacity is reset after the test?
