I'm running Exchange 2007 SP2/Windows 2008 Server in Active-Passive SCC cluster.
Last night, the CMS failed over from P1 to P2 it seems. I notice that because when I connected to ExchCMS this morning, I connected to P2.
I think there were some performance issues on the P1 server, but I'd like to know what actually caused the CMS to fail over? Is there a certain criteria? And what would we look for in the Event Log to show what caused it?
