2008R2 Cluster- How to remove application cluster IP

Hi All,

I have installed cluster on 2008R2; & i have installed SAP cluster on that as well, but due to some errors i need to roll back the SAP & re install it. But after i have completely uninstalled the SAP, the SAP cluster IP still exists on the adapter, how to remove this IP?

Now there are three IP's on te adapter
1) One is the physical IP of the adapter
2) Second is the windows cluster IP
3) Third is the SAP cluster IP (it exists even after SAP has been completely uninstalled)

How to remove the 3rd one?

Help me out with this

Many thanks in advance
