I have an existing server 1+ years old with 5 instances. I just received notice that the hardware genie will be visiting my company with a second node for my server.
Experienced in Win2003/SQL2005 clustering. This is now Win2008 and SQL 2008 R2 server components.
My plan idea is to make a DNS entry to Node1 data with the name of the cluster. In this true cluster do I still reference all instances via CluserName\InstanceName ? My fake DNS entry will be MyCluster.
MyCluster\ERPProd
MyCluster\InHouseProd
Or is clustering different with respect to instances?
As I tweak my code over to MyCluster\ERPProd I can then set up MyCluster as a cluster after we drop the fake DNS.
Does this make sense?
