Any data center server move from one rack to another, while the server is alive, is a potentially hazardous undertaking.Â Â It went something like this:
Me: OK, we have to be careful with this part.
Me: OK, ease it up a little more.Â WAIT!Â Something’s caught
Me: Oh crap!
Things are all fine now, but that was an unpleasant and unexpected emergency. Â Moving servers live is always fun, but it’s definitely safer to take them down first, but on servers that are downtime sensitive, sometimes you have to try it the risky way.
