Microsoft Failover Cluster Manager



In this tip, I'll show you a few management tasks that may help the novice. Most tasks will be carried out using Failover Cluster Management which is the management console built into Windows Server 2008. You can access the Failover Cluster Management in a couple of different ways: Go to Server Manager, Features, Failover Cluster Manager.

In some cases, it may be necessary to uninstall and reinstall the Windows Failover Clustering feature on a server that is currently a member of a Failover Cluster. This can be done via either Server Manager, or PowerShell. Below are the steps to complete the process using each method. These instructions document the process for Windows Server 2012 R2, however the steps are similar for other versions of Windows.

Uninstall the Windows Failover Clustering feature via Server Manager

Complete the following steps with a user account that has administrative rights over the cluster, from any server that has access to the cluster. If the desired server is not listed, first add it by clicking Manage > Add Servers in Server Manager.
