We have a 2000 cluster that needs to have SP4 installed. I know that SP4 is cluster aware, but as far as I can tell this will take the cluster offline to install the SP and will cause huge problems for our users.
Can anyone tell me if there is a way of installing the SP on both nodes without encountering any downtime for our users? I hope that I can install SP4 on the passive node then failover and install it onto the old active (now passive) node?
Any help would be appreciated.
