It did not go well. One of the screws in the boot drive removable tray stripped out. That taught me to always check the torque setting on the screwdriver. I had to go back home to get a GraBit and dig it out. When I got back to the datacenter... I found that the new disk controller for some reason absolutely refuses to work at all in the classiccmp motherboard. No clue why - tested it in other machines and it works fine. Just not in the classiccmp server. This puts me in the fun position of having a perfectly functioning system sans drives, and weeks of work (data) on a set of drives - neither of which can be connected together. The only thing I can think of is a new M/B but I really don't want to do that. I'll call escalade/3ware on monday. Wasted day. Everything was finally put back the way it was. I'll keep ya'll posted.
