Performing a Reconfigure for vSphere HA

[handian08]

Hello, 

What should i do if i got this error on Skyline Health

"Performing a Reconfigure for vSphere HA operation on a primary node may cause an unexpected virtual machine failover"

Hi,

Did you do any reconfiguration of the HA or adding/removing any ESXi hosts of the Cluster?

Because that is when you do any changes on one of the ESXi hosts, the primary node in this case.

Double-check if all ESXi hosts are correctly configured with HA.

Last case, disable HA. Let vCenter remove all HA agents from ESXi hosts, wait a bit and then enable HA back again.

PS: If this is a production environment, you should do this task only after hours and if you have any critical VMs running on that Cluster, you should schedule a maintenance for this work.

Good reply, I was just going to suggest to be safe un-configure and re-apply HA to the cluster.

It should just work. We're on ESXi 7.0u3a, but we added this in 7.0u3...

Just click the "Add" button, put the Option name as "das.config.fdm.unknownStateMonitorPeriod" then set the value as "30" and hit OK!
