Thanks for the quick response. You were correct, VSC had nothing to do with it. After 6 hours, a complete rebuild of the host, updating of all the firmware on the host, I finally have it solved. I did two different things in the end and then I could add storage. I am not sure which one did the trick:
- I turned off and then back on flow control on the ESX host
- I change the nic order for my storage vSwitch. It has two nics, both active, and I change the order they appear
If you are in IT long enough there are always a few long nights, this was one of them. It is 1:30am and I am heading home.
