Environmental Sensing Card Test (sentest)
5
-
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 utilizes the uscsi command interface to send requests and receive status information from the SEN card. 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 4096), 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 setting correctly if another instance is changing the setting.
sentest Options
Figure 5-1 sentest

Table 5-1 sentest
| sentest Options | 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 Offline mode. 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 above
|
sentest Test Modes
-
sentest supports all three modes. Each mode performs a different test scheme on the SEN card.
-
Table 5-2 sentest
| Test Mode | Description |
|
| Connectivity Mode | Checks the device connection by opening the device. If the device does not open, the device is not connected. |
| Online Mode | Performs the same test as Offline mode. sentest does not support interactive test types. |
| Offline Mode | Checks three components within the enclosure. It checks alarm enable/disable, alarm time setting, and the drive's LEDs. It does not test the power on/off function (only functions whose values can be changed are tested). |
