Followed these Instructions
------------------------------------------
Step 1. Ensure you are logged onto your Passive Node with the Domain Admin Account.

Step 2. Go to DOS and execute the SP3.exe update with the "/passive" command.  - This will launch the installation and should now by-pass the Cluster check and you shouldn't receive the 11009 Error message.  

Step 3. Once the Installation is completed your passive node should re-boot, now go to your Active Node.

Step 4. On the Active Node - open failover clustering and Pause the Passive Node and stop the SQL Services on the Active node.

Step 5. Ensure your Services are configured in Step 2.  and launch the SP3 Update.exe. - Allow the installation to complete (it will probably ask for a reboot do not reboot yet).

Step 6. Un-Pause the Passive Node in the cluster, restart your SQL Services. then Reboot the Active Node.
