SunVTS 5.0 Test Reference Manual

Chapter 22 Environmental Test (env4test)

env4test exercises and validates the I2C bus on the Sun Ct800 systems.

There are nineteen subtests in env4test that test and report the status of the following:

env4test is not scalable.

env4test 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.

env4test Options

Description 

LEDS ON Continuity test 

Asserts all LEDs in the system display panel except for the PDU LEDs. This verifies the ability of the System Controller Board (SCB) to perform sequential writes while automatically advancing the address pointer internally. 

Slot LEDS test 

Repeatedly flashes all I/O slot LEDs. 

Disk LEDS test 

Repeatedly flashes all disk LEDs. 

Power Supply LEDS test 

Repeatedly flashes all power supply LEDs. 

Fan LEDS test 

Repeatedly flashes all fan LEDs. 

SCB LEDS test 

Repeatedly flashes all system controller board LEDs. 

FTM LEDS test 

Repeatedly flashes all front transition module LEDs. 

Green LED Blink test 

Tests hardware functionality that enables blinking for the green LEDs. 

Register R/W test 

A pattern write test to interrupt registers and LED registers (read/write) to isolate the stuck-at-1, stuck-at-0, and cross talk fault categories. The test execution time from shortest to longest is: 3N march, 5N march, Cross Talk. 

FRU Presence test 

Reads and displays FRU presence signals. 

Health test 

Reads and displays I/O slot health signals. 

Reset test 

Sequentially resets individual I/O slots. 

Power Supply test 

Tests the remote power on/off signals in systems with redundant power supplies. This test is only valid when 2 power supplies are inserted in a single drawer. 

Fan test 

Tests the functionality of fan speed changes. 

Poll interval 

Displays all system environmental statics every poll_interval seconds.  

Temperature Status test 

Identifies the current temperature of the CPU, the ambient temperature of the system, and verifies that the temperature is within normal operating parameters. This test is enabled in all modes. 

Power Supply Status test 

Detects assertion of Presence signal in the SCB and reads the power supply status register via the I2C bus. The encoded bit status is displayed to the console. 

Fan Status test 

Detects assertion of Presence signal in the SCB and reads the fan status register via the I2C bus. The encoded bit status is displayed to the console. 

All tests 

Executes all tests sequentially. 

env4test Test Modes

env4test supports Connection and Functional tests as described in the table below.

Table 22-2 env4test Test Modes

Test Mode 

Supported? 

Description 

Connection 

Yes 

Reports the status of the power supplies, the temperature sensors within the system, and verifies normal operating parameters. 

Functional 

(offline) 

Yes 

Tests the disk back panel, front panel LEDs, and fan control circuitry. Also uses the same functionality as Online mode and Connection test mode.

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".
