You can choose how you install, configure, and administer the SunPlex system from several user interfaces. You can accomplish system administration tasks either through the SunPlex Manager graphic user interface (GUI), or through the documented command-line interface. On top of the command-line interface are some utilities, such as scinstall and scsetup, to simplify selected installation and configuration tasks. The SunPlex system 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 3.1 System Administration Guide for complete descriptions of the administrative interfaces.
