VxRail: Event Code: VXR500TMP0203
Summary: This article gives details on the event code: VXR500TMP0203
Symptoms
VXR500TMP0203
Message
CPU arg1 temperature is greater than the upper critical threshold.
Arguments
- arg1 = CPU number
Cause
Some causes can be poor air flow, high inlet temperatures, fan obstruction, or sudden spikes in CPU utilization.
Resolution
Environmental:
- Check system fans for obstructions.
- Check inlet thermal temperature.
- Verify that the ambient temperature is within thresholds.
Server:
To ensure the iDRAC is functioning correctly, power the drain node and monitor for reoccurrence. If physical access to the node is not available, perform a remote power drain VxRail: How to perform remote auxiliary power drain of a node through the iDRAC
System settings:
iDRAC9 may report CPU x temperature greater than the upper critical threshold events when the CPU workload spikes at or near CPU Power Max. When transient power bursts occur to meet additional CPU demand, the processor temperature may briefly exceed the upper critical threshold. For example, a server that is operating at 50-60% utilization and spikes to 100% utilization for 5-20 s may exceed the upper critical threshold for CPU temperature briefly. When this threshold is exceeded, events are recorded in the System event log and Lifecycle Log. When the peak transient spike is over and CPU temperature returns to normal, an event is recorded indicating CPU x temperature is within range. This is seen more often when c-states or on-demand Turbo Modes are active. iDRAC 4.22.00.00 and iDRAC9 4.40.00.00 contain improvements to thermal algorithms.
