DL380p G8 fan control problems

[BenceDeminger]

Helo,

I am new here and my english is not too good so sorry for it. And I am not an expert so sorry for my stupid questions too.

I have a dl380p gen8 server and it is running for 4 mounths without any problems but yesturday the fans started run on max speed. I didn't do anything with it, i mean i didn't install any other hard drives or pci card or anything so i don't know the reason for the fan problem.

I made a lot of diagnostic and test (with ilo and Intelligent Provisoning) but all of the results are ok. I have no idea what cause the max fan speed so can somebody help me or do somebody has an idea howe to solve it?

[Torsten.]

go to the ILO diagnostics page, any issues there?

[BenceDeminger]

I don’t see any problem but here is the screenshot

Hi  BenceDeminger 

Try to do ILO RESET to reset all sensors.

ILO4 - > diagnostic -> reset

After, look the fans runs normaly

ILO-> System information -> FAN

[BenceDeminger]

I did it and it makes an interresting effect.

after the reset the funs run normally at first.

1,2 and 3 runs on 11%   4 runs on 34%   5and6 runs on 42%

the first 3 starts rise 1% by 1% and when they reached the limit of the 4th (34%) the 4th starts rise with the first 3 slowly

and when they reached the level of the 5th and 6th thely did the same, Slowly go faster and faster till they reach the 100%

and i reset the ilo again and it did the same. Any idea about this?

(I hope that you can understand the situation because my english)

What information is shown in the server IML and the iLO log?  What is shown on the iLO page that shows the sensor temperatures?

[BenceDeminger]

The IML contains only this lines multiple times

 BenceDeminger, the HDs are genuine of HPE ?

When the hd is not genuine the ILO can't manage the sensor of HD, so runs faster to protect the systemboard.

When you access the Intelligent Provisioning are fans runs faster ?

Can you  do the diagnostic test by intelligent provisioning in  Insight the diagnostic ? (nedd acces by F10 in boot)

Not always. Generally when this comes into play the sensor called 'HD Max' is missing which is not the case here.  If the ROM or iLO or in an odd state the fans will spin up to max.  Try resetting ROM with SW6 on the system board and set iLO to factory defaults

[BenceDeminger]

I read about the harddisks but i think this is not the problem because the server runs with this hd-s since i bought it and till yesturday i never met with this problem

I will try to reset the rom a few hours later and i will Tell you the results

[BenceDeminger]

So
I did the resets and some othet things.
I figured out that one of the hdds gives constant 50C value to the ilo HD-MAX “sensor” and this is why the fans run on high speed. When i remove this hdd the othets give a 35C value witch is low enough to the fans to run on normal speed but when i put back that hdd it gave the 50C value again so the fans run on max.
How can i reset the hdd’s max temperature value? Because i think that the hdd gives it’s maximum vaule, not the actual and this is the problem. Is there any sollution for this problem?

[Jimmy Vance]

You cannot modify the disk temp values

[BenceDeminger]

It’s ok but can i reset the max temp of the hdd?

It happend to my DL380P G8.
I just take out it's fan plate from the back of it and remove the dust on it with air blower. now it's again silent.
