Platform Names and Groups (Reference)
You need to know your system architecture (platform group) if you are adding clients for a network installation and the platform name if you are writing a custom JumpStart installation rules file.
Some examples of platform names and groups follow. For a full list of systems, see Solaris 9 Sun Hardware Platform Guide.
Table 39-1 Example of Platform Names and Groups
Note - On a running system, you can also use the uname -i command to determine a system's platform name or the uname -m command to determine a system's platform group.
