  • Page 31 SunVTS Overview You can use SunVTS, the Sun Validation and Test Suite, to run individual tests for verifying the configuration and functionality of most hardware controllers and devices. These are the main features of the SunVTS environment: • SunVTS kernel ( vtsk ) The SunVTS kernel controls all aspects of the testing.
  • Page 32 • Running individual tests from a command line Each individual hardware test can be run from a UNIX command line. It is useful to run a single test if you are validating a piece of hardware. The following documents provide information about SunVTS. They are available on the Solaris on Sun Hardware AnswerBook.
  • Page 33 Power-On Self-Test (POST) The Power On Self Test (POST) diagnostics reside in the system's OpenBoot PROM located on the system board. These diagnostics are useful in determining if a portion of the system has failed and should be replaced. Under normal operating conditions, POST does not run automatically when the system is powered on.
  • Page 34 The second way to start POST is by setting the diag-switch? NVRAM variable to true and then power cycling the system. To set the diag- switch? variable to true, type setenv diag-switch? true at the system ok prompt. ok setenv diag-switch? true Turn the power off, wait a few seconds, and then press the power on switch.
  • Page 35 To return to the default setting: ok setenv diag-level max To observe POST messages on serial port A, you must connect a terminal to port A or set up a tip connection to another workstation. For information about setting up tip connections, refer to the Solaris software reference manuals. 3.3 POST Progress and Error Reporting While POST is running, observe the Caps Lock key on the system keyboard.
  • Page 36 3.4 Additional Keyboard Control Commands • Stop Key If the diag-switch? variable is set to true but you want to bypass POST when the system is powered on, press and hold the Stop key on the keyboard and turn on the system power. This causes POST to be bypassed. •...
