Rule "Not Clustered o the Cluster Service is up and online. " FAILED, The machine is clustered but the cluster is not online.
One day in one of my Active-Passive cluster environments while
patching SQL Server 2012 environment I found the below Error. Here are the
observations
1) Failover cluster Health is good, all the roles, drives and nodes are running fine. Both the nodes are running pinging one to another.
Though the Error message says cluster is disabled or needs to start, cluster service is running fine in the services.msc
Below are the error screenshots.
The below command did the trick in my environment. Seems to be issue with MOF files.
mofcomp C:\Windows\System32\WBEM\cimwin32.mof
