Environmental Test (env6test)

env6test exercises and validates environmental subsytems. This test contains subtests to exercise a system's fans, keyswitch, LEDs, power supplies, and temperature sensors.

This test is not scalable.

env6test Test Requirements

In Functional test mode, if two or more of the following tests: ssptest, i2c2test, or env6test are selected under the "Other Devices" category, the group concurrency for this category should be set to 1. This setting will prevent any potential test failures due to the limitations in the Host to ALOM (Advanced Lights-Out Manager) interface.

env6test Options

To reach the dialog box below, 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 may not include the device appropriate to this test.

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 may only be available as a 32-bit test. For more information refer to the "32-Bit and 64-Bit Tests" section of the SunVTS 5.1 Test Reference Manual (816-5145-10).
