SunVTS is Sun’s online validation test suite. With VTS, you can verify the functionality of most of Sun’s hardware devices. You can use the SunVTS tests to stress certain areas of the system as needed fordiagnostic and troubleshooting purposes

Use SunVTS to test one device or multiple devices. Some of the major test
categories are:
Audio Tests
Communication (Serial and Parallel) Tests
Graphic/Video Tests
Memory Tests
Network Tests
Peripherals (Disks, Tape, CD-ROM, Printer, Floppy) Tests
Processor Tests
Storage Tests

The SunVTS program is run when the superuser types one of the following commands. The ex /opt/SUNWvts/bin directory needs to be defined as part of the PATH variable
sunvts – Runs the SunVTS kernel and default graphical interface
(CDE) on the local machine
sunvts -l – Runs the SunVTS kernel and OpenLook graphical
interface on the local machine
sunvts -t – Runs the SunVTS kernel in TTY mode, vtstty
sunvts -h host_name – Runs the graphical interface on the local
machine while connecting and testing a remote machine

If you use the SunVTS software in TTY mode, no frame buffer is required. To run in TTY mode, perform the following steps:
1. Start the SunVTS kernel with the vtsk command.
# /opt/SUNWvts/bin/vtsk
2. Start the SunVTS TTY User Interface with the vtstty command
# /opt/SUNWvts/bin/vtstty
or the sunvts command with the -t option.
# /opt/SUNWvts/bin/sunvts -t

The following requirements must be met to run SunVTS on a remote system:
1,There must be network connectivity between the local and remote system.
2,You must install the same revision of SunVTS on both the local and remote system.
