In this chapter, you learned that testing your cluster configuration is very important before deploying your cluster on the production environment. You saw how to perform tests of hardware and network failure and how to check whether the test was successful or not. You should come up with additional cluster failover tests to cover as many scenarios as possible. The failover tests depend on the cluster infrastructure and cluster configuration and are specific for every cluster. The cluster administrator should have an idea of which tests should be performed. By thoroughly testing your cluster configuration, you can prevent unwanted cluster service downtime.
