Cannot complete the configuration of the HA agent on the host

I enabled HA on a new cluster the other day and one of the hosts came back with the following error:

On ocassion, I have seen weird HA errors where simply selecting the ‘Reconfigure for HA’ on the host fixed the issue. I tried this, but the same error was seen. I next selected the host and went to Tasks & Events – Events. From there, I found the following error message:

Selecting the message and under Related Events selecting Show displayed:

Looking at the VMkernel interface, everything appeared to be configured correctly. I ensured the IP configuration was correct and that no duplicate IP issue was being experienced. So what was causing the problem?

Looking at the VMkernel interface again, I realized that for some reason the interface was selected as a Management Interface. Since a Management interface already existed and all other VMkernel interfaces in the cluster did not have this option selected, I figured I found the problem. I removed the checkbox and then selected ‘Reconfigure for VMware HA’ and the problem was solved. This is a great justification for using host profiles to ensure all hosts are configured identically.

    Was looking for a solution and had a miss match in the vmk0,1,2,3,4 on 5 different hosts. This worked xD
