voltage sensor and raw_command #124

Open Aaron811020 opened 1 year ago

Aaron811020 commented 1 year ago

Under the RMCP interface, I run get_device_sdr_list to get sensor info. The threshold of voltage would be over 100. And another question, could you provide the example of raw_command on the RMCP interface? I just can get the response"\xd4" now.

Result: {'data': <pyipmi.utils.ByteBuffer object at 0x7fd6a7c37ac0>, 'id': 3823, 'version': 81, 'type': 1, 'length': 49, 'owner_id': 32, 'owner_lun': 0, 'number': 59, 'entity_id': 7, 'entity_instance': 43, 'initialization': ['scanning', 'events', 'thresholds', 'hysteresis', 'type', 'default_scanning'], 'capabilities': ['auto_rearm', 'hysteresis_read_and_setable', 'threshold_readable'], 'sensor_type_code': 2, 'event_reading_type_code': 1, 'assertion_mask': 31252, 'deassertion_mask': 31252, 'discrete_reading_mask': 16191, 'units_1': 0, 'units_2': 4, 'units_3': 0, 'analog_data_format': 0, 'rate_unit': 0, 'modifier_unit': 0, 'percentage': 0, 'linearization': 0, 'm': 16, 'tolerance': 0, 'b': 163, 'accuracy': 0, 'accuracy_exp': 0, 'k2': -3, 'k1': 0, 'analog_characteristic': ['nominal_reading', 'normal_max', 'normal_min'], 'nominal_reading': 196, 'normal_maximum': 221, 'normal_minimum': 176, 'sensor_maximum_reading': 255, 'sensor_minimum_reading': 0, 'threshold': {'unr': 230, 'ucr': 225, 'unc': 221, 'lnr': 161, 'lcr': 166, 'lnc': 176}, 'hysteresis': {'positive_going': 1, 'negative_going': 1}, 'reserved': 0, 'oem': 0, 'device_id_string_type_length': 198, 'device_id_string': b'3.3VSB', 'next_id': 3890}

I do not get your question about the threshold. What do you expect?

About the other question: what command do you try to send? did you establish the session?

Aaron811020 commented 1 year ago

@hthiery thanks for your reply a lot.

For the first question, if I get the sensor reading of 3.3VSB with IPMITool, I will get the threshold values between 2.7 and 3.8. But I got the threshold values over 100 by rmcp interface. For the second question, The session is established, because I can get sensor reading. I want to use “ raw 0x06 0x52 0x07 0x78 0x02 0x79” to get the power status via the rmcp interface.

the reading of the thresholds is returned as raw reading .. you have to convert to a human readable value.

What command is that what you try to send? The return code 0xd4 says you do not have sufficient privilege level.
