remove named instance from sql 2012 failover cluster

  • In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.

    I removed it from the cluster but it is still there in the registry etc on the node I was working on.

    I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.

    I definitely don't want to remove one of the servers from the cluster.

  • The remove node is referred to a single instance, so removing a node from an instance is not the same thing as evicting a node from the cluster.

    I agree with you that the terminology can be confusing...

    Please note that when you install a new clustered instance, from the second node on you select the "add node to cluster" option, which is along the same lines as far as terminology is concerned.
