Hi, we have a 3 node HyperV Cluster Win2008R2 SP1. How to shut down all 3 nodes (for maintenance)? Quorum model is Node Majority , we have CSV with 800GB and 80VMs.
What is  the correct way to shut down. What is the best practice?

Thank you
John

Assuming you have a maintenance window and users are advised of the planned outage

Open the failover cluster manager right click on the cluster you want to shutdown and selec <more actions> then <shut down cluster>

this will save the state af the Guest VMs and stop the clustering services on all nodes

Once you have caries out your tasks open the Failover Cluster Manager again, right click on the cluster and select <start cluster>

Your Guest VMs will resume automatically

Thank you HyperAdvisor.

Yes, we have an maintenance window and users are informed.

So I don´t have to save the VMs before "<more actions> then <shut down cluster>"?

Also setting the nodes in maintenance mode is also NOT necessary?

And is there any order after that in shutting down the nodes or something to do with the CSV?

Thank you
John

Hi John

No you don't have to save the VMs before hand - check the settings of your VMs to see what action will be taken when the node stops - the default is <Save State> other options are <Turn off Virtual Macine> or <Shutdown guest OS>

Setting the nodes in maintenance mode is not necessary as this is done when the Cluster in shutdown

No specific order, VMs will be Saved/shutdown on each host, the first host with all VMs secured will have its cluster services stopped then the next and the next

Note: It you have SCVMM, when you bring the cluster back online you will get a lot of errors about missing VM details etc, ignore these for a while, they are because the VMM was not aware of the shutdown and will go away after about 15 minutes

Hope this helps

Hi HyperAdvisor,
thanks for this fast and accurate solution.
After shutting down the cluster from the cluster-manager, we shut down all cluster nodes.
After starting all nodes, all VMs are automatically startet on the nodes on wich it where running before maintenance.

Thank you!
