Issue

Various sensor-related alerts can be generated on Element storage nodes as a result of issues with the node's underlying Baseboard Management Controller (BMC) and/or the internal hardware components (fans, power supplies, etc) that the BMC manages.

These include:

Error Code	Error Details	Node Component
fanSensor	`FanXX RPM is failed or missing`	Chassis Fans
sensorReadingFailed	`sensorReadingFailed: IPMI diagnostics are currently unresponsive. Please contact support if this problem persists.`	BMC
tempSensor	`Error checking sensor for Exhaust Temp` `Error checking sensor for Inlet Temp`	Temperature Sensors
nodeHardwareFault	`Error checking sensor for Fan<#> RPM`	Fan RPM Sensors
nodeHardwareFault	`BMC Self Test failed. This may impact IPMI based services and a BIOS/BMC update may be recommended`	BMC
nodeHardwareFault	`IPMI diagnostics are currently unresponsive. Please contact support if this problem persists.`	BMC

The associated impacts of the various sensor alerts range from none (false positive alerts at particular Element versions and node types) to impacting node an cluster performance.

Use this article to determine and pursue the troubleshooting path for the particular collection of alerts on the cluster in question.
