Cluster-Aware Updating cannot update this failover cluster. - Error: The failover cluster nodes must be enabled for remote management via WMIv2

Question

I have run the the "WINRM QUICKCONFIG –q" command and it is enabled at all Host Nodes.

Answer 1

Hi Panagiotis,

Hope you're doing well.

According to Microsoft documentation, one of the requirements for using Cluster-Aware Updating (CAU) is that all nodes in the failover cluster must be configured for remote management via Windows Management Instrumentation. This is necessary because CAU uses WMI to perform various operations on the cluster nodes.

To resolve this error, you need to ensure that WMI is enabled on each node of your failover cluster. By default, enabling remote management might involve setting up a firewall rule to allow automatic restarts triggered by WMI events. However, it's crucial that WMI itself and Remote Registry are allowed through the firewall as well.

Here are some steps you can follow:

1. Verify that an administrator account has local administrator rights and permissions on all cluster nodes.
2. Use the "Validate a Configuration Wizard" provided by CAU tools to check if there are any other issues preventing CAU from running properly.
3. Ensure that each node's Group Policy Object allows Remote Management and includes any necessary exceptions or configurations related to CAU.
4. Check if there are any additional software or third-party services installed on your nodes that might interfere with WMI access.

Answer 2

Hello Ian Xue Thank you for your answer. As you can see from the Cluster Updating Readiness Results, I am getting 2 errors about WMI & PSRemote, but both are installed and enabled in all nodes. I have just notice that in the past month the end customer has install "Microsoft Monitoring Agent" in all nodes. Can this cause the issue?

Hey,

Check the firewall on the hosts. Firewall should have firewall inbound rule for Windows Remote Management (HTTP-In). https://learn.microsoft.com/en-us/windows-server/failover-clustering/cluster-aware-updating-requirements

In addition, you should try:

1. Enable-PSRemoting - force
2. To confirm the state use: get-service winrm
3. To enable the remote rule to enable remote shutdown open Windows Firewall with Advanced Security
4. Set Inbound Rule for Remote Shutdown (RPC-EP-In) to Enabled
