You can choose how you install, configure, and administer the Oracle Solaris Cluster software from several interfaces. You can perform system administration tasks either through the Oracle Solaris Cluster Manager graphical user interface (GUI) or through the command-line interface. On top of the command-line interface are utilities, such as scinstall and clsetup, to simplify selected installation and configuration tasks. See Administration Tools in Oracle Solaris Cluster 4.3 System Administration Guide for more information about administrative interfaces.
