Environmental Test (env3test)

env3test is an environmental control test for the Sun Blade 1000 and Sun Blade 100 systems. The test monitors the system by reading temperatures and fan speeds, as well as their limits. It reports whether the temperatures and fan speeds fall within system environmental condition limits.

The MAX1617 temperature sensor keeps 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 keeps 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.

Note - If env3test fails to register temperature values, the system temperature indicators may be faulty.

Note - env3test will not run on operating environments earlier than the Solaris 8 10/00 operating environment.

env3test 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. Refer to the SunVTS User's Guide for more details.

If the Log File option is set to True, the test logs two lines of information read from the system into the log file /var/opt/SUNWvts/logs/env3test.log. The first line is a time stamp. The second line is a list of names and the read values, as shown below:

Wed May 24 13:55:57 2000 system-fan , 19, cpu-fan , 49, power-supply-fan , 100, cpu , 81, cpu-ambient ,24

The values for fan settings refer to the percentage of performance at which each fan is running. The system fan, for example, is running at 19% of its capacity. The temperature values are in degrees Celsius. The cpu in the above example is running at 81 degrees C.

env3test Test Modes

TABLE 20-1 `env3test` Supported Test Modes
Test Mode	Description
Connection	Attempts connection to the device.
Functional (Offline)	Reports the received information to the GUI logging window in verbose mode.

env3test Command-Line Syntax

/opt/SUNWvts/bin/env3test [standard arguments] -o dev=driver_name, logging=true|false

TABLE 20-2 `env3test` Command-Line Syntax
Argument	Description
`dev=`driver_name	Specifies the driver name for this test. The driver for the Sun Blade 1000 is `max1617`.
`logging=`true\|false	Enables or disables the logging feature.

Note - 64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname. 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 32-Bit and 64-Bit Tests.
