HA and Alarm Host connection failure

[tuscani]

This is driving me mad.. I am getting the "Alarm Host connection failure" false alerts whenevr HA is enabled. I have tried unchecking\rechecking, restarting hosts, removing\readding to vCenter and confirmed DNS settings. The only thing that makes them go away is disabling HA entirely. We are on 4.1U1 (502767).

Ideas?

Did you contact VMware support about this?

[tuscani]

I have not.. and it's happening even with HA disabled.. just not as often.

what if you disable HA on the cluster, as well as manually uninstall the HA agents from the host(s) in question.  From there, enable HA again on the cluster

Doesn't unchecking HA automatically remove the agents?

[Troy_Clavell]

you may want to confirm those agents exist or not.  If they do, doing a manual uninstall may help.

Ok.. I will give it a shot.. thanks!

We have been getting this error ever since we upgraded to vSphere 5.0.

Our issue has been resolved by increasing host heartbeat timeout for vCenter Server.
