Failover Clustering and Network Load Balancing Team Blog
This blog will discuss the proper process for shutting down an individual node in a Windows Server 2012 R2 Failover Cluster or the entire cluster with all the nodes. Note: While the steps outlined will be specific to Windows Server 2012 R2, the process applies to a cluster of any OS version.
When shutting down or rebooting a node in a Failover Cluster, you first want to drain (move off) any roles running on that server (such as a virtual machine). This ensures that the shutting down of a node is graceful to any applications running on that node.
When the node is once again powered on and ready to be put back into service, use the Resume action to re-enable the node to host roles.
Shutting down the entire cluster involves stopping all roles and then stopping the Cluster Service on all nodes. While you can shut down each node in the cluster individually, using the cluster UI will ensure the shutdown is done gracefully.

I've a quick Question...Can you please explain technical differences between drain (move off) and manual Failover of all the individual services? For example, Let's say..I've a Clustered SQL Server Instance, what's difference does it make from SQL Server perspective if I failover SQL services to the otehr node and reboot the node vs Drain Roles and reboot the node?
Putting a node into maintenance mode by invoking the node drain is a management paradigm. Technically under the covers it exactly the same thing as going and manually discovering all the groups on a node and then manually issuing a group move. Drain just makes it easier... it's a single click action. But either way works, so do what you prefer.
Thanks Elden for the clarification...
Thanks Elden for sharing the same ...
Does shutting an hyper-v cluster stop all running VMs?
Hi Elden Christensen,
Thanks for good Artical about How to Properly Shutdown a Failover Cluster or a Node.
I am planning to learn from scrarch Could you please provide the PDF file on Clustering on Windows 2008 server.
