You can choose from several user interfaces to install, configure, and administer Sun Cluster and Sun Cluster data services. You can accomplish system administration tasks through the documented command-line interface. On top of the command-line interface are some utilities to simplify selected configuration tasks. Sun Cluster also has a module that runs as part of Sun Management Center that provides a GUI to certain cluster tasks. Refer to the introductory chapter in the Sun Cluster 3.0 System Administration Guide for complete descriptions of the administrative interfaces.
