  Identify your needs to determine how to design your cluster.
• Cluster security
  Consider some of the security issues you need to consider when you plan to use clustering on your systems.
• Cluster configuration checklist
  Complete the cluster configuration checklist to ensure that your environment is prepared properly before you begin to configure your cluster.
• Cluster deconfiguration checklist
  If you need to delete a cluster or a CRG, you must systematically remove different cluster components to ensure complete deconfiguration.
• Plan for a cluster administrative domain
  The cluster administrative domain requires planning to manage resources that are shared among nodes within a cluster administrative domain.
