Environmental Test (envtest)
-
envtest exercises the I2C bus on the Ultra(TM) 4, Ultra Enterprise(TM) 200, and Ultra Enterprise 400 product lines. Five subtests are in envtest 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.
envtest Options
FIGURE 12-1 envtest
-
TABLE 12-1 envtest
| envtest Options | Description |
|
| Disk LEDs Test | Illuminates each LED on the disk backplane(s) to green, then amber, and then back to its 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. |
| 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 its 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. |
| Power Supply Status | Identifies the number of power supplies that are in the system, 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, the ambient temperature of the system, and verifies that all temperatures are within normal operating parameters. This test is enabled in all modes. |
envtest Test Modes
-
envtest supports Connection and Functional tests.
-
TABLE 12-2 envtest
| Test Mode | Description |
|
| Connection Test | Reports the status of the power supplies, the temperature sensors within the system, and verifies normal operating parameters |
| Functional Test | Tests the disk back panel, front panel LEDs, and fan control circuitry. Also uses the same functionality as Online mode and connection test If you invoke SunVTS through SyMON, the following Functional Test description applies: Uses the same functionality as connection test (above)
