Issue

  • EMS log reports the following events and the PCISW_Die_Temp sensor returns a correct reading and the sensor events are de-asserted within one minute.

Example:

00:09:59 [node1: env_mgr: monitor.chassisTemperature.cool:alert]: Chassis temperature is too cool: NVS PCIe Die Temp is critical low (0 C).
00:10:00 [node1: monitor: monitor.globalStatus.critical:EMERGENCY]: Chassis temperature is too low.
00:10:20 [node1: env_mgr: monitor.chassisTemperature.ok:notice]: Chassis temperature is ok.

  • Service Processor (SP) reports the following assertion errors in the system event log (SEL) and these errors are de-asserted within one minute.

Example:

23:00:26 [IPMI.notice]: 1800 | 02 | EVT: 01500005 | PCISW_Die_Temp | Assertion Event, "Lower Non-critical going low " | Reading: 0.000 | Threshold: 5.000
23:00:26 [IPMI.notice]: 1900 | 02 | EVT: 01520000 | PCISW_Die_Temp | Assertion Event, "Lower Critical going low " | Reading: 0.000 | Threshold: 0.000
23:00:26 [IPMI.notice]: 1a00 | 02 | EVT: 0301ffff | Attn_Sensor1 | Assertion Event, "State Asserted"
