Sorry for the late response (divorce, it turns out, is very time = consuming). I will try to send you scripts later on, but I did not automate things through the iDRAC. I managed to get an AMD machine, but unfortunately non of the tests run on that machine. I am still trying to figure it out. I will update you once I make progress.
