Understanding Cluster Validation Tests: Cluster Configuration

Cluster configuration tests make it easier to review the cluster settings and determine whether they are properly configured. The cluster configuration tests run only on existing clusters (not servers for which a cluster is planned). The tests include the following:

• List Cluster Core Groups: This test lists information about Available Storage and about the group of resources used by the cluster itself.
  
  
• List Cluster Network Information: This test lists cluster-specific network settings that are stored in the cluster configuration. For example, it lists settings that affect how often heartbeat signals are sent between servers on the same subnet, and how often they are sent between servers on different subnets.
  
  
• List Cluster Resources: This test lists details for all the resources that are configured in the cluster.
  
  
• List Cluster Volumes: This test lists information about volumes in the cluster storage.
  
  
• List Clustered Services and Applications: This test lists the services and applications configured to run in the cluster.
  
  
• Validate Quorum Configuration: This test validates that the quorum configuration is optimal for the cluster. For more information about quorum configurations, see Understanding Quorum Configurations in a Failover Cluster.
  
  
• Validate Resource Status: This test validates that cluster resources are online, and lists the cluster resources that are running in separate resource monitors. If a resource is running in a separate resource monitor, it is usually because the resource failed and the Cluster service began running it in a separate resource monitor (to make it less likely to affect other resources if it fails again).
  
  
• Validate Service Principal Name: This test validates that a Service Principal Name exists for all resources that have Kerberos enabled.
  
  
• Validate Volume Consistency: This test checks for volumes that are flagged as inconsistent ("dirty") and if any are found, provides a reminder that running chkdsk is recommended.
