You can run tests in one of two modes:
Connection test mode--a low-stress, quick test to verify the availability and connectivity of the tested device.
Functional test mode--a more robust testing capability that uses whatever system resources are required for thorough testing, and assumes that there are no other applications running.
Functional test mode when executed from SyMON invokes non-intrusive tests that do not significantly affect other applications.
Not all tests run in all test modes. In this case, the test is disabled and the test name displayed on the SunVTS test selection panel appears lighter, indicating that the test is unavailable for the selected test mode.
