Cannot remediate host because it is a part of a HA admission control enabled cluster

If you get the error “The operation is not supported on the selected inventory objects. Check the events for the objects selected for the operation” when you try to remediate a host you will also find the following entry in the eventlogs:

“Cannot remediate host because it is a part of a HA admission control enabled Cluster”

Solution:

To patch the host you will have to disable the HA Admission Control Policy during the time you need for the update. To do so just click right at your cluster – Edit Settings – vSphere HA:

    Actually you don’t have to modify cluster settings – after you put the host in maintenance mode and do a remediate select in the remediation dialog setings Disable HA Admission Control and that will allow you to update the host without modifying Cluster setings
