Last night I have been messing around with a Dell C6100 units with four nodes with each two 82576 adapters. At some point I installed PROset one of the nodes in order to try out teaming. Later I decided teaming was not needed any stupidly decided to remove the teaming software - without removing the 2 adapters from the team - result is that I now have one node which is under the impression that it has no network cards.
Re-installing PROset fails because no adapters could be found, I took a drive out of another node (with and without proset installed) to see if this would uncover anything - but no luck. It seems something has been written to the cards so that they will not announce themselves anymore.
I tried reflashing the BIOS and BMC, but this did not have any effect.
Anybody have a clue what I could do to get the adapters alive again?
