When you add a managed host to the Sun Management Center topology, you must associate the host with a shared profile. The shared profile describes the configuration characteristics to be used for the installation of that managed host.
A shared profile can be used by one or more managed hosts. For example, if you have 100 managed hosts running search engine software and the hardware configurations of these managed hosts are the same, the same shared profile can be used by each managed host. Any per-host differences must be specified in the host properties.
A shared profile must specify the Solaris Flash archive you want to deploy. In addition to specifying the archive, the shared profile specifies configuration data that is used to install and configure the software on managed hosts. This configuration data (sometimes called sysidcfg data or custom JumpStart data) includes information about the network interface, naming service, security protocols, and disk layout.
