Hi,
We have a 3 node cluster running Windows Server 2012 R2 with 5 SQL clustered roles running SQL 2012 spread across them. For certain reasons we have a requirement to install a second SQL named instance onto one of the existing SQL roles. All of our SQL instances are currently running on different ports with no issues.
When we run the wizard to install the additional instance we specify the new instance name along with the existing network name to install to. However, we receive this error message:
"The SQL Server failover cluster instance name <existing role name> already exists as a clustered resource. Specify a different failover cluster instance name."
I am wondering if it is by design that it doesn't allow you to do this or a limitation of the GUI install? Is running multiple SQL named instances on a single cluster resource group/role supported?
Cheers
Brady
