Hi

We had a power outage recently and I had to restart one of the esxi hosts. It come back up online fine but the master host seems to be giving an HA error and I'm not sure why as they host it complains about is online.

See attached grab of vCentre.

1. on each Host - Reconfigure HA

2. if that does not work, Edit Cluster settings, and Un-tick HA, and Close, and then Edit Cluster Settings again, and Enable.

also check if you can resolve and ping the fqdn as shown, it seems to be complaining about not being able to reach an IP address and hostname.

DNS has not changed? IP Address not changed?

I can reconfigure for HA on each host and it will not have any impact on services or VM's? Sorry I've never had to do that before so it's new to me!

Same question applies to 2.  Can I do this without effecting anything?

No it will not affect running VMs.

VMware HA will only run, when a Host fails.

If that fails, disconnect that host in vcenter and just add it back in, that will often fix that. Sometimes you will need to migrate everything off, put into maintenance mode and then disconnect/reconnect.
