Had a minor problem with a host that was not able to configure HA agent after a vCenter update, 6.5 build 15000 to build 21000. It was the only host in the cluster that had the error.
Tried:
– set the host in and out of maintenance mode and to move the host out and in of the cluster. Did not help.
– disable and enable of HA on cluster level work for all the other host, but not my stubborn one.
Reading a VMware 2056299 told me to manuel uninstall the HA vib (vmware-fdm) with
esxcli software vib remove -n vmware-fdm
After successfully uninstall i took the host out of maintenance and did a Disable/enable HA on cluster level, and volia it now works.
GUI is always a bit slow to update, but with PowerCLI you get current status.
PS C:\> $clusterName = "Cluster1"
PS C:\> Get-Cluster -Name $clusterName | Get-VMHost | Select Name,@{N='State';E={$_.ExtensionData.Runtime.DasHostState.State}}
