Cluster test tool

The Cluster Test Tool is a utility that lets you test a PowerHA® SystemMirror® cluster configuration to evaluate how a cluster behaves under a set of specified circumstances, such as when a node becomes inaccessible, a network becomes inaccessible, a resource group moves from one node to another, and so forth.

You can start the test, let it run unattended, and return later to evaluate the results of your testing.

If you want to run an automated suite of basic cluster tests for topology and resource group management, you can run the automated test suite from SMIT. If you are an experienced PowerHA SystemMirror administrator and want to tailor cluster testing to your environment, you can also create custom tests that can be run from SMIT.

It is recommended to run the tool after you initially configure PowerHA SystemMirror and before you put your cluster into a production environment; after you make cluster configuration changes while the cluster is out of service; or at regular intervals even though the cluster appears to be functioning well.

Note: The Cluster Test Tool is not fully supported by the latest PowerHA releases.
