You can install Solaris software from a local DVD-ROM or from a network installation server by using the JumpStartTM installation method. In addition, Sun Cluster software provides a custom method for installing both the Solaris OS and Sun Cluster software by using the JumpStart installation method. If you are installing several cluster nodes, consider a network installation.
See How to Install Solaris and Sun Cluster Software (JumpStart) for details about the scinstall JumpStart installation method. See your Solaris installation documentation for details about standard Solaris installation methods.
