- Chassis over temperature errors are reported every hour in the event logs:
[Node1: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: Ambient Temp is critical high (120 C).
[Node1: statd: monitor.shelf.fault:alert]: Critical fault reported on disk storage shelf attached to channel 0b. Check fans, power supplies, disks, and temperature sensors.
[Node1: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: Midplane 4 Temp is warning high (47 C).
[Node1: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: Midplane 3 Temp is warning high (47 C).
[Node1: monitor: monitor.globalStatus.critical:EMERGENCY]: Chassis temperature is too high..
[Node1: env_mgr: callhome.chassis.hitemp:error]: Call home for CHASSIS OVER TEMPERATURE
