Hi everyone. Strange VMware problem we are having here and looking for idea.

vSAN running two hosts and a witness. For the vSAN portion, each node is connected to a Cisco 3850 via a pair of twinax cables. On one node there are no lights on the switch where the twinax connect. This was working before. I have tried the cables elsewhere and they work. I have tried other ports on the 3850 and it doesn't work there either. Dell just replaced the network card and it didn't help. On the switch, "sh int status" shows the twinax is plugged in, but not connected. Same for the server.

VMware shows nothing unusual other than the connection is down.

Again, this was working. Problem is only one node. The other one is fine as is the witness.

Anything else?
