Chapter 49 Environmental Sensing Card Test (sentest)

sentest checks the SCSI Environmental Sensing card (SEN) installed in the SPARCstorage RSM to monitor the enclosure environment. The SEN card monitors the enclosure's over-temperature condition, fan-failures, power-supply failures, and drive activity.

sentest verifies the SEN card by first setting each control function to a predetermined value, and then reading it back to verify if the value is correct.

sentest verifies the following control functions in the enclosure:

• Alarm (enable/disable)--sentest toggles the alarm to the disable state, then to the enable state.

• Alarm time (0-0xff seconds)--sentest sets the time (from 0 to 4095), then reads it back to verify the time setting.

• Drive fault LED (DL0-DL6)--sentest toggles each LED to its OFF and ON states.

sentest is a nonscalable test. It cannot verify the control function settings correctly if another instance is changing the setting.

sentest 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.

Figure 49-1 sentest Test Parameter Options Dialog Box

Table 49-1 sentest Options

sentest Option	Description
Test Type	Specifies the test to be performed. Norm test type performs normal testing as alarm enable/disable, alarm time setting, and drive LED on/off testing. Interactive test type reports the current enclosure status.
Enc_state	Specifies which subsystem's status in the enclosure is reported. Default is ALL. This test is only used with the inter test type and in Functional test. The test options are:  oAlarm enable/disable status   oDrive present status  oDrive LED status  oPower modules status  oFan modules status  oOver temperature, abs (abnormal, no immediate attention needed), chk (abnormal, immediate attention needed) status  oAll of the above

sentest Test Modes

sentest supports all three test modes. Each mode performs a different test scheme on the SEN card.

Table 49-2 sentest Test Modes

Test Mode	Supported?	Description
Connection	Yes	Checks the device connection by opening the device. If the device does not open, the device is not connected.
Functional  (Offline)	Yes	Checks three components within the enclosure. It checks alarm enable/disable, alarm time setting, and the drive LEDs. It does not test the power on/off function (only functions whose values can be changed are tested).

Table 49-3 sentest Command-Line Syntax

Argument	Description
dev=interface	SEN card device name. The default value is ses0.
test=type	Specifies the test type. Select Norm for normal testing or Inter for interactive testing; the default value is Norm. Possible values are: norm and inter.
enc=component	Indicates which part of the enclosure status is reported. The default value is ALL. Possible values are: enalm, dp, dl, pm, fan, ovt, and ALL.

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".
