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 48-1 sentest Test Parameter Options Dialog Box

TABLE 48-1 `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: Alarm enable/disable status Drive present status Drive LED status Power modules status Fan modules status Over temperature, abs (abnormal, no immediate attention needed), chk (abnormal, immediate attention needed) status All of the above

sentest Test Modes

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

TABLE 48-2 `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 48-3 `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 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.
