About SunVTS Software
SunVTS, the Sun Validation and Test Suite, is an online diagnostics tool and system
exerciser for verifying the configuration and functionality of hardware controllers,
devices, and platforms. You can run SunVTS using any of these interfaces: a
command-line interface, a TTY interface, or a graphical interface that runs within a
windowed desktop environment.
SunVTS software lets you view and control a testing session over modem lines or
over a network. Using a remote system, you can view the progress of a SunVTS
testing session, change testing options, and control all testing features of another
system on the network.
Useful tests to run on your system are listed below.
