How to configure prevered cluster node in failover cluster manager

If you use the failover cluster manager in Windows Server 2012 R2 you have the option to set a prefered cluster node to hold your cluster roles like virtual machines.

Why should you use this option? Easy answer, there are scenarios where you want to prevent cluster roles to run on the same node. In my case I want to prevent to run guest cluster nodes and virtual domain controllers on the same node.

So if one node failes, I have the failover virtual machine running on the other hyper-v cluster node.

You can easily configure the option in the grafical interface. To do so, you can follow my screenshots.

Open the failover cluster manager and click right on the VM or role you want to change

In the context menu select Properties

 

In the properties - general menu you can select the prefered cluster node or nodes. After selecting the node please click on Failover

Now you should configure the fallback option. I would suggest to configure fallback and a period from 1 houre before you VM or roles falls back to prefered node. That prevents you to run into issues if a node failes again short after   he returns to the cluster.

  1. Great post. But well to keep guest cluster VMs on different nodes I would try to use Anti-affinity Rules in the Cluster (PowerShell): http://www.scug.nl/infrastructure/separate-vm-in-hyper-v-virtual-machines-using-anti-affinity-winserv-hyperv-drs/

    Or if you are using System Center Virtual Machine Manager I would use Availability Sets: http://www.thomasmaurer.ch/2013/07/how-to-configure-availability-sets-in-virtual-machine-manager/

    I use the preferred Node option if I have a stretched Cluster over multiple sites.

      Hey Thomas, thank you. 🙂

      And as ever you are totally right. If you run a bigger cluster than my two nodes or us SCVMM anti-affinity rules or avail. sets are more usefull and reduce the administrative effort.
