I have a Dell DSC6005/C6105 server (it says DSC6005 in the firmware, but according to the internet it's actually called C6105). EDIT: The DCS6005 is an unofficial OEM that uses the same chassis as the C6100.
One of the nodes had trouble with its IPMI interface, so I attempted to reset it. That was clearly a wrong move, because the IPMI interface came in a boot loop. When I am pinging it, I observe it answering 62 times, then going down for about 46 seconds and the story repeats itself.
Remote ipmitool
commands time out with Error: Unable to establish LAN session
and the BIOS reports BMC: Not working
. Luckily it doesn't stop the node from booting, it just takes a couple of minutes more. Taking out the power and removing the CMOS-battery do not change this.
According to the Dell support forums, one can attempt a System reset, which at this point is the only way out I can think of, apart from replacing the node. But from this thread I don't understand which jumper I need to set. My hardware matches the photo in that thread, not the drawing. From what I understand, this should be some jumper, but I simply can't find it. My searches to documentation for this board also came up short.
