Issue

  • Several high temperature warnings for the NVRAM M2 module. Example:

... node_name: ALERT monitor.chassisTemperature.warm: Chassis temperature is too warm: NVRAM M2 Temp is warning high (67C).
... node_name: env_mgr: monitor.chassisTemperature.warm: alert: Chassis temperature is too warm: NVRAM M2 Temp is warning high (67C).
... node_name: env_mgr: callhome.chassis.hitemp: error: Call home for CHASSIS OVERTEMPERATURE
... node_name: monitor: monitor.globalStatus.critical: EMERGENCY: Chassis temperature is too high.

  • All other temperature sensors for that module or any other IO expansion cards in the controller are correlated (increasing/decreasing when data center temperature or air flow changes)
