Environmental Test (envtest)
|
envtest Description
envtest exercises the I2C bus on the Sun Enterprise
450 product line. envtest contains five subtests to test and report on the power supply status, system temperature status, fan speed, disk LEDs, and front panel and keyswitch.
envtest is not scalable.
Note - Do not run envtest while the system is under a heavy load or false failures may be reported.

envtest Options
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.

Description
|
Disk LEDs test
|
Illuminates each LED on the disk backplane(s) to green, then amber, and then back to the original state. The test then illuminates all disk LEDs to green, then amber, and then back to their original state. This test is only enabled in Functional test mode.
|
Fan test
|
Cycles each fanbank speed to low, medium, and high, then verifies the correct speed. Next, each fanbank is stopped, one at a time. The test then verifies that a fan fault has occurred. Next, the watchdog timer is invoked to simulate a catastrophic failure. The test verifies that the system set all fanbanks to high and then resets the fan speed to normal. This test is only enabled in Functional test.
|
Front Panel and Keyswitch test
|
Flashes each individual LED on the front panel to on (green or amber), then off, and then back to the original state. The test then illuminates all front panel LEDs then sets them back to their original state. The Power On LED is read-only and will not be cycled. The test then displays the current keyswitch position. This test is only enabled in Functional test mode.
|
Power Supply Status
|
Identifies the number of power supplies that are in the system, and the state of each power supply, and verifies that the power supply temperatures are within normal operating parameters. This test is enabled in all modes.
|
Temperature Status
|
Identifies the current temperature of each CPU in the system, and the ambient temperature of the system. envtest verifies that all temperatures are within normal operating parameters. This test
is enabled in all modes.
|
envtest Test Modes
envtest supports Connection and Functional test modes.

Test Mode
|
Description
|
Connection
|
Reports the status of the power supplies, the temperature sensors within the system, and verifies normal operating parameters.
|
Functional
|
Tests the disk back panel, front panel LEDs, and fan control circuitry. Uses the same functionality as online Functional mode and connection mode
