Installing Service Pack on Active/Pasive Cluster Windows 2008 SQL Server 2008

Please click the link below to watch the video from You tube. 

SP on Active/Pasive cluster

Addition notes from the Video.

Imagine
node#1 active
node#2 passive(install on passive node first) as per the video.

Open the Cluster Manager

1-  In cluster manager - right click sql server network cluster name - properties - advanced - then uncheck the     passive node#2(this is because we dont want it to fail to this node during the install since it can corrupt binaries)
2- install SP on passive node#2 (make sure sql services stopped on this node, etc)
3- once installed  manual failover services from node 1 to node 2 and update SP on node 1
 steps: A- SQLserver network cluster name advanced and re-select node 2 to add it back in. 
        B- In Cluster Manager move services(current owner)over to node#2 (now that its been patched)   
        C- Now remove node#1 by right clicking  sql server network cluster name - properties - advanced then uncheck node#1
4- install SP 1 on node#1
5- After install complets on node#1 we need to set owners again. Right click sqlserver network cluster name properties  - advanced and re-select node#1 to add it back in.
6- Fail services back to primary node and start services.

And before you move the resources to Node1 Open Management studio and verify the Service Pack and version. Please make a note of the version before and after installation, that way you can verify that SP has been completed installed.
