Dear All,

We have Active-Passive SQL Server 2008 R1 Cluster set up on Windows 2008 R2. Now we want to add another instance to this cluster. Can you help us in detailing the desired steps?

Do we need to create a new cluster (hence assigning new IP/Name/Disks other than existing cluster) or we can use the existing setup to perform this activity?

You will need to install SQL Server again for the new instance.
You will need a Virtual Server Name (A unique name used to identify the virtual server on your network)
You will need a static unused IP address to identify your instance.
You will also need a minimum of 1 shared disk to keep your data files.

Yes, you can use existing setup to do that.
You have to install SQL Server as a named instance. You also have to configure SQL Server cluster resources: ( physical disk, Ip address, shares and etc.) and dependencies.

Adding a second instance is no different than what was needed for the first instance. Follow those same exact steps, but with unique information (virtual name, IP, ...)

Why should it be different? Sharing storage is sharing storage.
