SERVER 2012 FAILOVER CLUSTER – HYPER-V – Errors after Security Updates

Setup a Windows Server 2012 Failover Cluster with two hosts and a backend SAS SAN (Dell MD3200 with Dell Dual Port 6Gbps HBAs).

Did a number of tests and failover of VMs from one host to the other worked great in restarting one host or the other. Livemigration and moving storage ownership between the two was working. I was missing a few windows updates on one to have it completely up to date so I did those. Now  after restart (and I’ve tried several restarts) the cluster doesn’t come up immediately and it takes about 5 minutes of thinking and trying before it comes up when logged into windows.

Here were the updates done:

Should I just try removing one at a time and seeing which culprit caused the issue? Or is there a better way at handling this so that I can still have the windows updates?

The Critical error in the system log is:

Task Category: Resource Control Manager
The cluster Resource Hosting Subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually associated with recovery of a crashed or deadlocked resource.  Please determine which resource and resource DLL is causing the issue and verify it is functioning properly.

Was the Cluster Aware Updating feature used to run updates against the cluster?

Have all of the relevant Cluster hotfixes and patches been applied?

I'm new to setting up clusters in Hyper-V and wasn't aware of Cluster Aware Updating feature? How does one use it? Should I uninstall the updates and and reinstall with this feature?

The link provided references server 2012R2, not 2012.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

2012 RTM Cluster hotfixes and patches.

Click Start --> type Update and it will come up in the results.

There were some serious bugs in 2012 RTM. If this is a lab setting start fresh and use the hotfix/patch list. Then go CAU.

Thanks. Wouldn't just doing Windows and Microsoft Updates to present install all of those patches, instead of manually seeing if one by one they are installed?
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
Some are hotfixes and don't get published to WU/MU.

We run the necessary hotfixes/updates in the applicable list. Then we run Cluster Aware Updating to finish the job.

Hi Philip,

Thanks for your input. I eventually figured out the issue a few weeks back, it was stupid simple. When I did the update a couple of months ago on one of the hosts, it somehow set one of the services that Hyper-V Uses to Automatic (Delayed). I checked my other Hyper-V environments and they weren't set to Delayed. So I unset that and that fixed the issue of the 5 minute delay of the cluster coming up on the host.
