症状

CPU utilization level too high. Reduce system load prior to NDU. (cpu_usage_level_exceeded)



As seen from PowerStore Manager:

原因

The existing checks used to find CPU usage include management and platform CPU cores. The result is that, on an idle system, it sometimes catches one of those cores running at over 50% and it fails the check.
 

解决方案

Most of these warnings are false positives, but careful verification should be carried out in order to avoid possible upgrade issues.

In order to confirm if this CPU warning is a false positive or a real warning, go to Hardware, then choose the appliance that is being marked for CPU issues. Go to the PERFORMANCE tab, and check the CPU utilization details. The general guidance would be:
  • If the CPU utilization is around or below 50%, the upgrade may continue.
  • If the CPU utilization is over 50%, the upgrade should be deferred to a period when the system is less busy.
 

Fix

This issue is fixed in PowerStoreOS version 2.1.x.
