After a reboot, a VMware ESXi 6.7 U3 told me that he has no compatible NICs. Fun fact: Right before the reboot everything was fine.
The ILO also showed no NICs. Unfortunately, I wasn’t onsite to pull the blade server and put it back in. But there is a way to do this “virtually”.
You have to connect to the IP address of the Onboard Administrator via SSH. Then issue the reset server command with the bay of the server you want to reset and an argument.
OA1-C7000> reset server 13
