To Clarify, when I say stacking, all I mean is to find those cluster groups that are not running on the preferred owners i.e. those that are stacked on a different node than the preferred owner.
After the monthly patching cycle completes, we used to spend a considerable amount of time figuring out if all the clustered SQL*Server instances were running on their preferred owners or not. During the latest cycle of patch deployment, I was hard pressed for time and wanted to see if I could put something together, quick and dirty, to display the information easily.
