Renaming Cluster name

    Is it possible to rename a cluster that is hosting an instance of 2005. The virtual server name and the instance name (default) will remain the same.

    Thanks

    Thanks for the replies but what I need to know is if it is possible to rename the cluster name. Say I have a cluster called CLUSTER1 and I have a virtual SQL server named SQL1 with a default instance. I want to rename the cluster to CLUSTER2. Will this affect the virtual SQL server?

    Thanks again

    The only proper way to do this is to uninstall SQL Server clustering, uninstall Windows clustering, then reinstall Windows clustering with the new name, then reinstall SQL Server clustering. I say "proper" way because there are hacks, but I don't like to use any hacks on any cluster.

    What is the reason renaming the server after cluster install?

    Comletly agree with Brad in this case and not a good practice to perform such system tweaking on CLuster, as it is meant of high availability that will cause an unexpected downtime.

    The reason the cluster is being renamed is dumb and out of my hands.

    I read where the "cluster" command has a "rename" switch but it doesn't mention the impact on SQL. From what I can find, renaming the cluster name resource seems like it won't impact the SQL installation. I am tempted to try it on a test cluster if I can get total access.

    Thanks for all the replies....

    Make sure all the dependancies are working with this rename, even SQL group.
