ML110 G7 - Strange fan behavior

Hi.

 

I have a ML110 G7 where the PCI fan runs constantly at 50% speed. I contacted HP and got a new fan. The new fan runs constantly at 47% speed. The server has 2 HDD and a P410i SAC.

During POST both the fans spin directly to this speed 50% or 47% and there is no change when the OS starts.

 

Anyone got an idea of what is failing?

 

Regards, Ingi.

Re: ML110 G7 - Strange fan behavior

Hello,

 

I understand that the fans are running at the constant speed but this is not a issue still I would suggest you to udpate the ILO firmware as ILO manages all the fans and other component.

 

Refer the link in order to update the firmware:

Re: ML110 G7 - Strange fan behavior

Hi.

 

I already have the latest ILO firmware. I beleive that this is an issue, I manage many other HP Proliants and none of them are running any fans at this speed when idle and even under heavy load I have not seen this fan speeds. The fan makes a loud noise and the server is in a quiet environment and therefore annoying.

To be more specific the new fan starts at 47% and after 10 minutes it starts going from 47% - 50% back and forth every 10-15 seconds. No load on server.

 

Regards, Ingi.

Re: ML110 G7 - Strange fan behavior

Hello,

 

As you mentioned that the ILO is up to date I would suggest you to download the smart start disk and run the offline diagnostic and provide us the report:

 

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=15351&prodSeriesId=5075942&prodNameId=5075943&swEnvOID=4064&swLang=8&mode=2&taskId=135&swItem=MTX-8d8870eebb4244918bd75303f4

 

Also please change the below provided option:

 

 

Regards

Abhishek

 

  1. Power on the server.
  2. Press the F9 key to enter RBSU.
  3. Select "Advanced."
  4. Select "FanSpeed."
  5. Set the defaultspeedof the fans to "low."

Re: ML110 G7 - Strange fan behavior

Hi.

 

Attached is the report.

 

The option you mentioned is not available. Under Advanced I only have Thermal Configuration and there I can either select Optimal Cooling or Increased Cooling. Optimal is selected.

Re: ML110 G7 - Strange fan behavior

Hi,

I am having the same issue with a new HP ProLiant Ml110 G7 assigned to me at my work place. Did anyone manage to resolve this issue?

Thnaks.

Re: ML110 G7 - Strange fan behavior

I have an open case with HP and have received a response saying that it's working as intended.

 

Unfortunately, the quickspecs say the server should run around 44 dB. Using two separate iPhone apps, I've got the sound measuring 73 dB (granted the iPhone isn't a dedicated sound meter, however, I'm reluctant to spend $300 on one just to prove a point with support).

 

The support case is still open. I would expect a rack-mount server to be this noisy, not a tower.

Re: ML110 G7 - Strange fan behavior

Just set up a new ML110 G7 and it is behaving the same way; fans constantly at between 46 and 55%.

 

Re: ML110 G7 - Strange fan behavior

Noticed another thing: if I reset the ILO3 from the ILO management page the fans will slow down and then over the next 10 minutes rev up to 50% even though the server is under light load at the time. This server replaced another ML110 G4 that was used for the same tasks and that server I never even noticed, fans were much more quiet.

Re: ML110 G7 - Strange fan behavior

Just posted a response in this thread about the same issue:

 

http://h30499.www3.hp.com/t5/ProLiant-Servers-ML-DL-SL/ML110-G7-Fan-noise/td-p/5375651

 

Re-seat the connection for the front fan. It may have become dislodged during shipping.

 

That resolved the issue for me today after a visit from a HP tech.

Re: ML110 G7 - Strange fan behavior

Just my two cents. Having the same issue. Tried everything from reseating the connector of the fan, resetting the firmwares of iLO and of the BIOS, clearing all of the memory, reinstalling the OS... Nothing works. Always running at 50%.

 

Really really annoying, when in fact this server is expected to run in the office.

Re: ML110 G7 - Strange fan behavior

I have also tried the suggested steps without success. I am convinced this is a BIOS issue; we sell HP servers and I have seen this on different models over the years, mainly on the low end servers. Hopefully HP will come out with a newer BIOS that fixes the problem soon.

Re: ML110 G7 - Strange fan behavior

Same issue.  The rear fan is the one running hard.  Tried reseating the front fan.  When I disconnect it the other fans spin up faster.

 

Opened case with Tech Support.  They are sending a new fan.  Even with the 4hr 13x5 carepack it will a couple of days before they deliver it.  ...so much for buying the carepack!

Re: ML110 G7 - Strange fan behavior

Hi

 

I received 2 ML 110 G7 yesterday. At first I inserted latest Firmware CD/DVD 9.30. Everything was up to date.

Then I installed OS (Server 2008 R2 - SP1)  + PSP 8.70. Both Servers are extremly loud! (Louder than our ML 350 G6 with redundant power supplies and 8 disks!) I don't know which of all the fan's produces the noise and it doesn't interest me!

 

There's something wrong! Replacing a/the fan/s isn't a solution!  I hope there is soon a new BIOS ver / ILO Firmware(?) to solve the problem!

Re: ML110 G7 - Strange fan behavior

I investigated two more days but didn't find a solution yet and in the link below you can find a few infos:

 

http://www.gibel.net/Blog/tabid/64/EntryId/22/HP-ML110-G7-strange-fan-behavior-extremely-loud.aspx

 

- during and ILO reset the "noise" disappears for a short time!

- tried to completely disable ILO => was a challenge to enable it again!

  (system board dip-switch 1 on => F8 during boot ...)

- I'm double - double checked that I have all the latest FW / Drivers! SystemManagement Firmware / Drivers are the most important!

- Opened CASE at HP => 2 solutions: 

  • move Servers (have 2 ML 110 G7)  to serverroom => but it's a small business server!! in my house I don't have a serverroom! => no solution
  • fill out DOA (defect on arrival) and hope to get money back.

 

 

My case at HP is sill open. A new Firmware/Driver for SystemManagement / BIOS should solve.

 

A colleague from work will give my a volume checking device to get the exact dBA - value (>> 27 dbA from Quick Spec)

Re: ML110 G7 - Strange fan behavior

I Also Have an ML110 G7 with the Fan Noise

But only when the Bios states the Ambient Temp reaches 30c

when its in location in a cool room no problems

 I want to get some more of these servers & the locations their going to will be over 30c IN SUMMER

& I know i will get complaints , I have already been through the above listed updates , etc

Please let us know what comes from this case. I have the same issue and this is very annoying. I'd like to get this fixed or returned.

Re: ML110 G7 - Strange fan behavior

Please find my action plan:

 

-Swap the fan with any other fan in the server and check if the fan speed remains high in the same slot or it follows the fan.

 

If the high speed follows the fan module to a different slot then we need to replace the fan and if the high speed remains with the same slot  irrespective of the fan module then we need to replace the system board.

 

Summarizing, inorder to resolve this issue we need to either replace the fan or the system board.

Please perform the above test to determine which part needs to be replaced and then log a case with HP.

 

Please visit the link given below to log a case with HP:

Re: ML110 G7 - Strange fan behavior

I had this same issue on a DL380 G7 last year - The cause was becaseu i had non HP hard drives in the server.

This was fixed by replacing all the hard drives

 

This has not been an issue on the ML110 G6's

 

Today I just built my first ML110 G7 with no HP drives and im getting loud fan noise.

What hard drives are you all using please? Could this be my issue again?

 

Thanks

Re: ML110 G7 - Strange fan behavior

Hi all:

 

The SOLUTION for me was to DISABLE the **bleep** iLO.

 

Go to the "HP Lights-Out Online Configuration Utility" and configure it on the setup

 

¿Easy?

Re: ML110 G7 - Strange fan behavior

So I bought a HP Proliant ML110 G7 a week ago. I installed an Ubuntu linux. Under the install configuration and after it the rear fan became verry-verry loud, and (I think) reached the highest spin. It was realy loud. I checked the temperature (it was about 28C in the room). So after several times of bios settings, browsing on forums, I turned of the PC and remove the cover. I removed the grey plastic cover from inside. And there WAS'NT a cooling radiator on the moatherbord.


Cooling Radiator Missed

 

Sry dont have a real picture, because I went to back the Market and tried to change it. The Sales manager wanted to sell an another Server (same type). I told: lets check it inside: and the radiator missing again....He told me: it is normal... WHAT??? Is it normal?  I can't believe. I asked to money back, and buy an another server.

So I think, the Coolers arent stupids maybe you have the same problem. If there is no Cooling Radiator, the temperature realy high near the Temperature sensor cable connector and it make fan to increase speed. 

Check it.

Re: ML110 G7 - Strange fan behavior

Having unsuccessfuly tried the methods mentioned - here's how I seem to have fixed my fan issue (Rear fan @ 50% - 54% regardless of ambient temperature or load).

 

Power on the server.
Press the F9 key to enter RBSU.
Select "Advanced."
Go into "Thermal Configuration and select "Increased Cooling."

Exit and restart server.

Using iLO all fans now run at around 47% and boy is it noisy.

Restart server and repeat process, setting "Thermal Configuration" back to "Optimal Cooling"

 

After this I had a very quiet ML110 G7. I hope this works for you.

 

Regarding the missing heatsink see HP's explanation.

Re: ML110 G7 - Strange fan behavior

Also getting fan issues.

 

For the first 24 hours of continuous running the fans were virtually silent. Then noticed that the fans had picked up pace dispite the room being no warmer than the previous day and the server wasn't under load.

 

iLO reported Fan 1 running at 50%, Fan 7 running at 47% and Fan 8 running at 10%

 

Checked seting of fans. Updated BIOS and firmware. Machine ran silently for 10 mins before fans picked up to their old speed.

 

Tried disabling iLO - no difference.

 

Tried setting to 'Increased cooling' then back to 'Optimal cooling' in the BIOS.

 iLO reported Fan 1 running at 54%, Fan 7 running at 46% and Fan 8 running at 10%

 

Reset iLO and instantly the macine fell silent.

 iLO reported Fan 1 running at 30%, Fan 7 running at 13% and Fan 8 running at 10%

 

After 10 minutes fans are back to their old speed:

 iLO reported Fan 1 running at 54%, Fan 7 running at 46% and Fan 8 running at 10%

 

Temperatures all seem reasonable, cooling seems excessive.

 

Any further advice on how to approach this problem?
