I intend to apply SP1 to a SQL2008R2 RTM active\passive geocluster.
Due to current issues with the disks with automated failover the passive node is paused to allow manual intervention.
Anyone patched a paused passive node, cannot see a problem and seems to me its similar to removing it from possible owners so should be fine, but would appreciate it if someone could confirm.

the recommended process to patch a 2k8 cluster with minimal downtime is to remove the secondary node as a possible owner, patch it, re-add it as an owner, failover to it, and then apply the patch to the now passive node.
there is a kb that walks you through the process.

You'll be fine. Its how I update all of my clusters

Pausing the node achieves the same and is much simpler

good stuff, always good to have verification. cheers

mysteryjimbo,
unfortunately having the passive node paused did not work for me. It caused SP1 to fail the 'is node clustered' check as it complained that either the cluster resource was down or the node could not communicate to the cluster.
I had to unpause it and remove it from the list of possible owners instead.
