I need help to create second instance on SQL 2008 Cluster. I have active/passive Windows 2008 R2 cluster and currently using a default instance of SQL. Most of the blogs mention that installation of new instance is same as the first one and you need to provide IP, network-name and disk resource. But when I use SQL installer to create new instance, it never asks me for IP and network name. As a result the new instance get created at the same location as the default one. I don't know where I am making a mistake. Is there a step by step guide for creating multiple instances on SQL 2008 cluster? Thanks for your help.
