I've recently installed Cumulative Update 6 for SQL Server 2014 SP2. I installed it on the passive node of a 2 node cluster. To install the patches I paused the role in cluster manager and ran the setup from command line with:
I now need to uninstall CU6 as we've come across some issues we need to resolve. However, I am unable to uninstall the patch as I cannot get past the rule checks. If I run the same command to start setup the UI does not give me the uninstall/maintenance options.
Is there anyway to skip rules to uninstall a patch, or am I going to have to remove this node from the cluster before I can proceed?
