False(?) "Storage system fan" alerts reported to OpenView

[Andreas Peetz]

Greetings all,

we have a number of ProLiant DL380 Gen9 servers used with VMware vSAN, equipped with 2x SSD and 14x HDD drives. They recently started to generate strange hardware events.

While in the iLO4 web interface no hardware alert is shown it still generates "Service events" for our OpenView instance from time to time that look like this in OpenView:

>>> Storage system fan status changed to degraded for location degraded connected to controller 50:6f:.....

In the iLO4 interface the event is shown in "Remote Support / Service Events" with

>>> Event Id = 500, Perceived Severity = 5, Event Category = HPQSS0500

However, the status of all components (including fans) is shown as green, and we do not know what the problem really is, or whether this is maybe just a false alarm. We do not have external storage connected to these machines, all disks are internal.

This may be related to firmware updates that were recently done. We are now at iLO4 version 2.80 and BIOS P89 version 2.74.

Has anyone else seen this or knows how to fix it?

Thanks

Andreas

Correction: iLO4 firmware version is 2.70
