Server Reboot – How to Reboot a Server in a Failover Cluster

failoverclusterwindows-server-2012-r2

We have a failover cluster manager managing 4 node(host) servers. How would I go about rebooting one of the nodes in the failover cluster.

Best Answer

  1. login to the HyperV host
  2. select Start> Administrative tools> Failover Cluster Manager
  3. Select Failover Cluster Manager
  4. Verify which server you need to restart (You can check the roles to see which host server, 'node', owns which guest server, 'role')
  5. Select Nodes, right click the desired server, and select Drain Roles (NOTE: make sure to verify the resources available to ensure the roles can be drained without causing issue. eg. enough RAM, CPU)
  6. Verify that the Roles have migrated successfully by selecting the Node, and navigating to the Roles tab
  7. Reboot the desired host
  8. after the reboot has successfully taken place, navigate back to Failover Cluster Manager> Nodes> Right click and select Fail Roles Back
