I am configuring Cluster-Aware Updating on a 5-node cluster. At this time I'm not enabling Self-Updating mode. Instead I'm going to use Remote-Updating mode. In the Cluster Aware Updating console I ran Analyze cluster updating readiness. I have two warnings that I can safely ignore (about local machine proxy and CAU clustered role not being enabled). But there is an error that I'm stuck on. Rule ID 13 gives me an error saying, "The configured CAU plug-in must be registered on all failover cluster nodes."
The resolution says to ensure that the configured CAU plug-in is inatlled on the all cluster nodes. I ran Get-CauPlugin | fl -Property * on each node and each of them returned the expected Microsoft.WindowsUpdatePlugin and Microsoft.Hotfix.Plugin listings.
Any ideas on how I can troubleshoot and get the error cleared?
