The Status column of the system sensors command output in the SL CLI shows the discrete sensors' conditions in hexadecimal values. To interpret the status values of most discrete sensors, you can use the system sensors get sensor_name command in the SL CLI.
Discrete sensors do not have thresholds. Their readings (displayed under the Current column in the system sensors command output) do not carry actual meanings and thus are ignored by the SP.
Examples of discrete sensors include sensors for the fan, power supply unit (PSU) fault, and system fault. The specific list of discrete sensors depends on the platform.
While the system sensors get sensor_name command displays the status information for most discrete sensors, it does not provide status information for the System_FW_Status, System_Watchdog, PSU1_Input_Type, and PSU2_Input_Type discrete sensors. However, you can use the following information to interpret these sensors' status values.
The System_FW_Status sensor's condition appears in the form of 0xAABB. You can combine the information of AA and BB to determine the condition of the sensor.
For instance, the System_FW_Status sensor status 0x042F means "system firmware progress (04), Data ONTAP is running (2F)."
The System_Watchdog sensor can have one of the following conditions:
For instance, the System_Watchdog sensor status 0x0880 means a watchdog timeout occurs and causes a system power cycle.
For direct current (DC) power supplies, the PSU1_Input_Type and PSU2_Input_Type sensors do not apply. For alternating current (AC) power supplies, the sensors' status can have one of the following values:
For instance, the PSU1_Input_Type sensor status 0x0280 means that the sensor reports that the PSU type is 110V.
