On a two node SQL 2012 cluster, I evicted the passive node and did an in-place upgrade from 2012 Standard to 2012 R2 Datacenter which happened fine without much issues.Now when I am trying to start the cluster services after installing the failover cluster role, its not starting and throwing me errors
Question - Does the SQL installation needs to be redone with failover clustering mode to fix the issue ? When I am trying to add this new upgraded node to the cluster , it says the Node is already added to the cluster which is not the case
Scenario
Two Node SQL 2012 Cluster Setup
Quorum Type - Node and Disk Majority
Active Node - Windows Server 2012 Standard
Passive Node - Windows Server 2012 R2 Datacenter (Upgraded from 2012 Standard) and having issues
Any help/assistance will be appreciated
