I am patching SQL server, going from SP1 to SP3, on a cluster while following Microsoft's instructions on how to do it.
Every single place I read tells me to do the following:
- Pause the passive node
- Update the passive node
- Resume the passive node
And then it goes on, but when I try step number 2, I get the following error in the analysis before actually updating:
Not clustered or the cluster service is up and online
If I try to do the update without pausing the node everything works fine, but I don't think that's a safe way to go.
What am I doing wrong here?
update: I was actually following Windows itself patching instructions which states that the node should be paused. The instructions on how to patch SQL don't include pausing/resuming the node. But still, I believe this would be a best practice since something can happen to the active node making the cluster attempt to failover to the node being patch, with the results of that being unknown to myself.
Does anyone know what would happen?
