SQL 2012 Failover Cluster Build (Step by Step) – Part 3:Adding a New Instance


This is my 3rd and last post of the series of building SQL Server 2012 failover cluster. This will cover the steps adding a new named database instance to the cluster that is already created. Please refer to the 1st part for understanding the context of the overall demonstration. You must finish part 1 in order to apply the steps defined here in your case.

Part 1: Installing SQL Server 2012 failover cluster

Part 2: Adding second node to the cluster

How-to steps

This will be very similar to SQL Server 2012 installation in part 1. So, the recommendations given there apply here as well. Assumed you logged in with a cluster admin account to Node1 or Node2.

In this post, I have shared with you the scenario of adding a new database instance to the SQL Server 2012 failover cluster that is created in the part 1. This is the last piece of the post series of implementing highly available SQL data services by utilizing clusters. But, not the last on High Available (HA) data services, which is one of the major enhancements of SQL 2012 Server. There are more to say about SQL 2012 Server HA features, added some resources below. Perhaps next time, we can dive into it, stay tunedSmile
