Environmental Test (env3test) |
env3test is an environmental control test for the Sun Blade 1000/2000, Sun Blade 100/150 and Sun Blade 1500/2500, and A70 workstation systems. Although the central function of this test environmentals and thus common to all these platforms, the exact behavior of the test is platform-specific.
For Sun Blade 100/150 and 1000/2000 workstayions, the test monitors the system by reading temperatures and fan speeds, as well as their limits. The test reports whether the temperatures and fan speeds fall within system environmental condition limits. The MAX 1617 temperature sensor maintains a set of hard limits for the maximum and minimum temperatures allowed within the system. If the temperature passes one of these limits, the system performs a hard shutdown to protect hardware components. env3test also checks against the environmental monitor daemon, which maintains its own limits. By reading these temperature values, the test reports the possibility of a failure of the system environmental feedback loop between the fans and the temperature sensors.
For Sun Blade 1500 and 2500 systems, the test displays the temperature sensors and temperatures, and all the fans and their speeds in RPM. The test has an option for logging this information. The test will fail if one or more fans are bad, are disconnected or are weak. An appropriate error message indicates a disconnected or bad case, or a weak fan case.
For the A70, the test displays the temperature sensors and temperatures, and all the fans and their speeds in RPM. It has an option for logging this information. The test fails if the fan status indicates a fan fault.
For Sun Blade 1500 and 2500, and the A70 workstations, the env3test supports the Exclusive and Connection test modes.
Note - On Sun Blade 100/150, 1000/2000, if env3test fails to register temperature values, the system temperature indicators could be faulty. |
Note - On Sun Blade 100/150, 1000/2000 workstations, env3test requires Solaris 8 10/00 OS or later. |
To reach the following dialog box, right-click on the test name in the System Map and select Test Parameter Options. If you do not see this test in the System Map, you might need to expand the collapsed groups, or your system might not include the device appropriate to this test. Refer to the SunVTS User's Guide for more details.
/opt/SUNWvts/bin/env3test [standard arguments] -o dev=driver_name, logging=true|false, fantest=enable, fan=All/intake-fan+outtake-fan
Note - 64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname, or the relative path to which you installed SunVTS. If a test is not present in this directory, then it might be available as a 32-bit test only. For more information, see 32-Bit and 64-Bit Tests. |
