HA agent has repeated error

[Keano]

I have 10 Esx 3.5 blades in a cluster. One of these servers repeatedly requires to be re-enabled for Vmware HA. I would like to avoid this re-occurring however nothing appears in the logs except that HA on the host had an error. Is anyone aware how to resolve this once & for all?

it may just be a simple name resolution issue. Check to ensure you can ping all the hosts by FQDN both for ESX and your vCenter Server.

Here's a good KB as well

Did you check the HA log files? They should give a hint why this happened.

I think you have answered this Troy, many thanks. nslookup on the FQDN returned the correct ip address. Nslookup on the address returned an entry for another server which I have corrected in DNS. I havent had the chance to reboot the host.

Troy, Having changed DNS, I rebooted the ESX host 2 days ago and havent had the error appear since. Many thanks.
