Installing SQLServer 2000 service packs on Clustered server



Hi,

I am planning to install sql server 2000 sp4 on my clustered server
running in active/passive mode.
I plan to stop all sql services using cluster administrator, install
the service pack from the primary node and then reboot all nodes.
Are there any missing steps that need to be done or problems that
anyone has come across?

Thank
Lyn
