How to update SQL Server 2005 clustered instances?

Question
We have a 3 node cluster with an instance running on each. Windows 2003 R2 32bit (16GB) / SQL Server 2005
I want to bring them all up to build 9.00.5266 (SP 4 + CU3) (1 Node is already updated) The links and articles I have found haven't been very helpful in terms of order installation and gotchas.
Our test cluster nodes were already at 9.00.5266. (My predecessor did that before I arrived).
I updated the test cluster instances to 9.00.5292 (Cluster only has 2 nodes) Although I got there, this did not go as expected....
The plan was :
- Move all instances to node2
- Update the instances on node1
- Reboot node1
- Move all instances to node1
- Update the instances on node2
- Reboot node2
- Move an instance to node1
I got to step 5. Then the installer said I had to use the active node. That means that the instance must go offline.
Is this a pitfall of SQL Server 2005 or am I doing this wrong?
Why did the first update work?
There are only few hotfixes available after build 9.00.5292 (All via links from MS upon request) so I can't experiment any further without reinstalling the test cluster.
I'm sure there are a couple of DBAs out there that have experience with updating SQL Server 2005 clustered instances. [Smile]
