Testing a PowerHA SystemMirror cluster

The Cluster Test Tool is available for you to test a new cluster before it becomes part of your production environment, and to test configuration changes to an existing cluster, when the cluster is not in service.

The Cluster Test Tool runs only on a cluster that has:

• If the cluster is migrated from an earlier version, cluster migration must be complete.
• The cluster configuration verified and synchronized.

  Before you run the tool on a cluster node, ensure that:

• The node has PowerHA SystemMirror installed and is part of the PowerHA SystemMirror cluster to be tested.
• The node has network connectivity to all of the other nodes in the PowerHA SystemMirror cluster.
• You have root permissions.

Because log file entries include time stamps, consider synchronizing the clocks on the cluster nodes to make it easier to review log file entries produced by test processing.
