We had a strange outage and now two of our M520 blades in the VRTX just show the iDrac Booting on the display on the VRTX. Whether this problem is related to the fact that the CMC is showing redundancy lost I'm not sure. I have tried reseating the CMC cards but the error remains. Is the firmware held on the SD card on the CMC? if it is what would happen if I swapped them?
CMC firmware 2.12
Main Board Firmware 2.21
