Issue

On AFF A700s systems, ONTAP reads incorrect sensor values for onboard sensors, which can lead to ONTAP reporting errors on multiple sensors.

The EMS log raises the following errors.

Example:

EMERGENCY monitor.globalStatus.critical: Chassis temperature is too low.

Chassis temperature is too cool: NVMe1 Temp is critical low (-91 C).

ALERT monitor.chassisTemperature.cool: Chassis temperature is too cool: RiserL LTemp1 is critical low (-48 C).

Chassis temperature is too warm: CPU0 Temp is critical high (39 C).

Chassis power supply 1 is degraded: PSU1 InVoltage is Critical Low (72000 mV)

Chassis power is degraded: Sensor detecting voltage anomalies.
