Secondary node corruption for SQL 2008 R2 Cluster

Hi Experts,

In my environment having an active passive cluster for SQL 2008 R2 on windows 2008 R2.

The sec node is corrupted and needs to be redeployed i.e OS needs to be installed.

In this case once the windows cluster is in place , understanding is that on the secondary node we just need to do a add node for the SQL Instance to create an active passive SQL cluster.

Thanks
