: The resolution in this article works only if your environment does not include NSX or VMware Horizon View or VSAN. To resolve this issue if your environment includes NSX/View/VSAN, contact VMware Support.
This warning does not have any impact on production and can be safely ignored.
To resolve this issue, restart the management agents (hostd
) on the host.
If the problem persists after restarting the management agents, remove the host from the cluster and then re-add it to the cluster:
- Place the host into maintenance mode.
Note: If DRS does not migrate the virtual machines to other hosts, migrate them manually.
- Ensure that there are no virtual machines running on the host.
- Remove the ESXi/ESX host by dragging it out of the cluster.
- Re-add the ESXi/ESX host by dragging it into the cluster.
- Exit from maintenance mode.
