vCloud Director reports ESXi host is down, when it’s not

Today (15/10/13) I’m messing about with VMware vCloud Director 5.1 and when I came to create my provider VDC I got an error stating that one of my hosts was down.

I checked my host and it was indeed UP not DOWN.

My fix was, stick the host into maintenance mode, do a reboot and then take the host out of maintenance mode.

I then went back into the vCloud Director Console and enabled the host; all was then good with the world.

I then had a look on Google and found the following blog on VMware’s Blog site.
