HPE BladeSystem c-Class enclosure fans are operating at a high speed
All fans in an HPE BladeSystem c-Class enclosure are operating at a high speed while fans in the other enclosures are operating at normal speed.
If all fan LEDs are solid green but the fans in the
chassis are operating at a higher speed than normal, then access the following information from the
Onboard Administrator or
iLO:
- Review the FAN section in OA SHOW ALL to locate the fan zone that is consuming more FAN speed.
- Verify the virtual FAN value for the affected servers within the FAN zone that indicates which server is consuming a lot of FAN speed.
Possible indicators could be either an outdated ROMBIOS or iLO firmware, or a server repeatedly going through POST or reboot.
If a single fan is operating at approximately 80% and the issue is resolved after resetting the Onboard Administrator, then upgrade to Onboard Administrator firmware 3.60 or later to resolve the issue.
