Patching a Windows 2008 SP2 Failover Cluster Procedure

  1. Identify the ‘Health’ of both the Active Node and the Passive Node.
  2. Move to the Passive Node and validate Cluster Groups and Cluster Resources are not associated with the Passive Failover Cluster Node.
  3. Focus on the Passive Node and place in ‘Paused’ State in Failover Cluster Management Console.
  4. Reboot Passive Node (I do this action as I have found it helps ‘identify’ problems even before a Patch is installed).
  5. Patch and Reboot Passive Node.
  6. Validate Passive Node Health.
  7. Move Passive Node from ‘Paused’ State to ‘Active’ State.
  8. Move Cluster Groups and Cluster Resources from Active Node to Passive Node.
  9. Focus on the Passive Node (originally was Active Node) and place in ‘Paused’ State in Failover Cluster Management Console.
  10. Reboot Passive Node.
  11. Patch and Reboot Passive Node.
  12. Validate Passive Node Health.
  13. Move Passive Node from ‘Paused’ State to ‘Active’ State.
  14. Move Cluster Groups and Cluster Resources from Active Node to Passive Node.
  15. Validate Service Availability from Client Perspective
