I have been testing on our X15. Everything seems to work as expected on 7.3.1

The problem repeats for me with every reboot. I get an IPMI event just after the array comes online. It lasts roughly 30 seconds and then another IPMI event when fan speeds return to normal. Diagnostics are attached. You should see the most recent event starting at about 8:02 am in the system log.

Are you able to provide screen prints of you fan control page and provide a copy of the fan control log?

root@Titan:/var/log# cat /var/log/ipmifan

After a little thought I believe I have found how you can reproduce this event. I recently made a change to my fan control settings-

I changed The temperature sensor for SYS_FAN5 and SYS_FAN6 from "Auto" to "HDD Temperature". When I reset this back to "Auto" I no longer get the IPMI events.

Sorry, I was unable to collect logs.

For info these are the settings we have setup on our X15 for disk temps. Not the override to something else for when they spindown.

Should be just cat /var/log/ipmifan

Copied your settings and that fixed the issue. I still don't understand what was causing it though. Can you explain?

Maybe because I was using HDD Temperature for HDD Spundown temp sensor also??? That's the only real difference I see in your settings.

Likely temp was null, so I might need to checks in place so you cannot use HDD for spin down override. It would have been trying to set fan to below minimums possibly.

@SimonF

What are you using for cpu fan settings?

Here are the settings we are using, but system is not used much at present. You can leave it disabled and the bios will handle the fan. In the BMC you can create new fan profiles.

I had it disabled and noticed that the cpu temp was 63C and fan speed was 0rpm. The readings tab was showing n/a for cpu fan speed so not sure if the readings in the footer could be trusted but I really didn’t like them so switched the fan to enabled in fan control.

Haven’t been able to repeat this though.🤷
