Hi David B,

Did you resume (unpause) the node after installing the hotfix? The pause will persist over the reboot.

If you did this and are still having issues, please send me an email by clicking on the 'email' link on the upper right.

Thanks,

Symon Perriman

I performed the steps outlined above.

I moved all active resources from Node B to Node A.

I paused Node B.

I applied updates and Service Pack 2 to Node B.

After rebooting, the Failover Clustering feature was no longer installed. Node A shows Node B as "down" at this time.

I reinstalled the Failover Clustering feature on Node B. Now the cluster service will not start on Node B. How can I bring Node B online so that I can update Node A?

Thanks.

Hi Ron,

Great question. You will want to run Validation *after* you have updated all of your nodes. Ideally you want to get out of this 'mixed mode' cluster as quick as you can as the cluster may not be as stable during this time (and running Validation will mean you're in mixed mode for even longer).

Once you have upgraded all the nodes and they're online (not paused), Validation will complete successfully.

Thanks,

You mention "A best practice is to also pause the node(s) you are about to upgrade by right-clicking the node name and selecting 'Pause'." Have you tried this? In fact you will see that you can't install the service pack onto a node that is paused. You will get the following error during the validation

checks:

"The machine is clustered, but the cluster is not online or cannot be

accessed from one of its nodes. To continue determine why the cluster is not

online and rerun setup instead of rerunning the rule since the rule can no

longer detect a cluster environment correctly."

So what is the best practice?

Thanks,

Ron

Losing your remote desktop connection is expected when the machine reboots during installation (or any time a machine reboots). This does not impair any functionality. Once the machine is upgraded you will be able to reconnect via remote desktop using the same credentials and machine information. The steps documented above were performed entirely using remote desktop.

Thanks,

There is an issue when you install Windows 2008 SP2 remotely, if you have RDP to the server. your installation shows installing physicaly standing at the front of servers.After RDPing to server & once SP2 starts installing your connection is lost, Microst should maintain connection &Admin shouldn't use 3rd party software to connect Server using KVM over IP.

I think Microsoft should address this if you are installing remotely.

Thanks
