Reinstall OES2 nod cluster

[kimmeriya]

Hi,
I have to reinstall my oes2(no sp1) server from scratch, this server is member on two-node cluster (NSS volume cluster), second node is oes2(no sp1) too.
My plane:
1.Delete server from the Cluster and disconnect HBA from the SAN
2.Uninstall eDirectory from the server and delete leaf objects from eDirectory
3.Install oes2sp1, install powerpath
4.Connect my HBA to the SAN, install Cluster package and configure it.

Is this the correct way?
Any suggestions?

Thanks
