discover4x analyzes the support that remains for SunOS 4.x clients after the server has been converted to Solaris 2.x.
The discover4x command is most commonly used after a SunOS 4.x server has been upgraded to a Solaris 2.x server. This command looks at the SunOS 4.x client support that exists and creates the databases that are required for installation of SunOS 4.x diskless/dataless clients on this Solaris 2.x server. If client support for a given architecture is missing, discover4x attempts to notify the user that they will have to re-install this support using install4x(1M) . If you are converting clients that have the same architecture as the server that was converted to Solaris 2.x, you must re-install that architecture using the install4x(1M) command.
