Microcode Levels
February 10th, 2009 Posted in IBMI was configuring our twelfth virtual host this afternoon and ran across a weird issue. You see, we buy IBM Blade servers that go through integration, which means someone else configures the hardware for us. Unfortunately, I don’t think they turn the hardware on and check things. Case in point: we had Blades with processors running two different microcode levels (think firmware for a processor).
Little did I know anything was wrong when I got a big fat blue STOP error. MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED was staring me in the face.
Remember, check your microcode levels if you see STOP 0x0000003E. It could save your life.
