Environmental Test (env2test)
|
env2test Description
env2test exercises and validates the I2C bus on the Sun Enterprise 250 systems.
Five subtests in env2test test and report the status of the power supply, system temperature, fan speed, disk LEDs, front panel, and keyswitch.
env2test is not scalable.
|
Note - Do not run env2test while the system is under a heavy load. False failures might be reported.
|
env2test 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.

env2test Options
|
Description
|
|
Disk LEDs test
|
Determines the number of disks that are present and the state of each disk. Illuminates each LED on the disk backplane to amber, and then back to yhe original state. The test then illuminates all disk LEDs to amber, and then back to the original state. This test is only enabled in Functional mode.
|
|
Fan test
|
Sets the fanbank speed to halfway between the current speed and max speed, then verifies the correct speed. Next, the fanbank speed is set to max speed, and the speed is verified. The fanbank speeds are then returned to normal, and then verified. This test is only enabled in Functional mode.
|
|
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 is not cycled. The test then displays the current keyswitch position. This test is only enabled in Functional mode.
|
|
Power Supply Status
|
Identifies the number of power supplies that are in the system and the state of each power supply. This test is enabled in all modes.
|
|
Temperature Status
|
Identifies the current temperature of each CPU in the system, the ambient temperatures of the system, the temperature on the SCSI and power distribution boards, and verifies that all temperatures are within normal operating parameters. This test
is enabled in all modes.
|
env2test Test Modes
env2test supports Connection and Functional tests as described in the table below.
TABLE 16-2 env2test Supported Test Modes
|
Test Mode
|
Description
|
|
Connection
|
Reports the status of the power supplies and 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 mode and connection mode.
|
