Moral or the story -- Unless it's your own private/personal test LPAR, the system will survive without your intervention, With your intervention; it takes time to get down as gracefully as possible and not so long to get back in flight. It will take longer to explain what you were doing and it will be very painful

There was a shory pause followed by some expletives and an immediate IPL of the system. I wouldn't attempt it on any system I cared about unless it was to attempt to avoid an impending IPL.
