Requirements for Using Hardware Diagnostic Suite
Since it is a part of Sun Management Center, you can only run Hardware Diagnostic
Suite if you have set up your data center to run Sun Management Center. This
means you have to dedicate a master server to run the Sun Management Center
server software that supports Sun Management Center software’s database of
platform status information. In addition, you must install and set up Sun
Management Center agent software on the systems to be monitored. Finally, you
need to install the console portion of Sun Management Center software, which
serves as your interface to the Hardware Diagnostic Suite.
Instructions for setting up Sun Management Center, as well as for using the
Hardware Diagnostic Suite, can be found in the Sun Management Center User’s Guide.
