HP ML350 Gen8 3D Sea map sensor - CPU temp BUG !!!

Hello,


I see having a BUG in 3d Sea Map for temperature of ML350 Gen8.

A technician open a server, do maintenance and forgot to put back the air flow Plastic repartition plate.

The server get some reboot after 6hours. I turned it off and i open-it.  I see the plastic air flow plate was missing. But the CPU2 was very hot, and CPU 1 not.

I go take a look in temperature sensor data.

Result : both CPU was 40°C temp.

after put back the airflow plate and turned on again 1 day, the CPU temp was SAME !

2 weeks after : SAME ! always 40°C !

 

One other thing : I don't get any CPU temp too high or any other alert ! No good !

Hello,

I confirm this bug was in HP ILO 2.50 and 2.55B too.

I upgraded yesterday another HP ML350P gen8 from 1.6 to 2.55(B) and now the CPU temp was always 40°C

I have some DL360P and the CPU temps was right with 2.55(B).  Apparently specific to ML350.

 

HP Staff : Please fix this bug. :)

Re: HP ML350 Gen8 3D Sea map sensor - CPU temp BUG !!! (fixed at 40°C or 104F)

Dear all,

 

I recently upgraded us ML350p Gen8, DL360e Gen8, DL360p Gen8, ML110 Gen8 and Microserver Gen8 to ILO 2.61 (august 2018).

The Bug of CPU temperature 40°C was still present and on all HP Proliant Gen8 servers.

Best Regards

Vincent


@HP Team  :  Is possible to create an issue about this bug ???

I have the same problem in a DL380p Gen8.

Just upgraded to 2.72 firmware and nothing changed.

I have another DL380p Gen8. with 2.02 firmware and the temp is working ok.

Unfortunately there is no way to roll back the firmware version, or it is?

Just updated the system BIOS to Version 2018.05.21 Rev. A and still cpu temp fixed to 40C

This is totally annoying because when the CPUs are 100% busy, the temperature goes up to 93C, which is below the manufacturer recommended temp.

I cannot believe a server from 2015 does not correctly control its own temperature...
