DL165 G7 / ESXi 4.1 fans at high speed problem

Hi,

I've got a problem i can't resolve:

On our 3 new G7 Servers with ESXi 4.1 the fans run for max. 12h with normal low speed, and then go berserk and stay there. This happens regardless if the server has load or not. Even whith no VMs running.
On normal "warm" reboot fans go at 4.500 rpm again for some hours.

The environment could not be of influense, the server rack ist climated at constant 18°C.

Hardware: DL165 G7, 1 CPU (Opteron 6136), 32GB RAM, 4 HDDs

BIOS is the latest 037 from 09-06-2010, after flashing BIOS defaults loaded. I tried serveral settings but this didn't do the trick so far.

Could someone help me out?

regards,

Rolf

hi,

if you have the latest firmware, and this problem is persistent, you have probably two posibilities :

1, test downgrade the firmware

2, open a HW call directly in HP.

PS: which type of Power profile do you have ???

max performance, balanced .....

Hi Michal,

I played with all settings i could imagine, PowerNow, Performance Profiles etc. This didn't change anything. Since all Servers have to work now I have not that much time playing with everything. This week another server will arrive, and that one will be playground until this issue is fixed.
The only thing I didn't try by now is to take the HP-ESXi 4.1 installation-CD, I used the original VMWare-CD. I tried to install the HP-Version on a DL120 G6, but that resulted always with a kernel-panik after 2Min. uptime with a fresh installation, me doing nothing. Weird.

b.t.w. We have 8 DL165 G6 running with ESXi 4.1, and they do their job as good as they could do.

Have a nice week!

Rolf

Hi Rolf,

i can really understand what you mean if your servers is in production, there is very small time window for downtime ( planed / unplaned ).

We are using mostly Proliant class ( DL 380 /580 ), but if i installed the Vmware i always done it from the original Vmware CD.

hope you will find the solution.

Hi again, give me the time, and if there's a solution I'll find it. Problem is: TIME!
If I get thru it I'll post it, if someone else already got there: plz share, no sense in developing the wheel over and over.

cheers!

Hi,

same problem here: after some time fans run with full speed. I also tried different power profiles without success.

I also tested the HP vmware version. There's again this weird kernel panic after 2 min uptime as with DL120 G6 of Rolf and DL 165 G6 (another server of me)

Unfortunately no solutions here until now.

Hi,

HP Proliant 100 series G7 servers incorporated an integrated thermal technology with HP DIMM modules depending on the data sent from the thermal sensor on HP DIMM modules the fan speeds are altered, in case there is an third party DIMM modules installed these might not have the thermal sensors and FAN speed runs to full throttle (the BIOS in ProLiant G7 servers verifies the presence of the thermal DIMM sensor during POST)

Also check if any optional FANs were installed and those are seated properly.

Uh-oh. My customers will call me names if I tell them they have to replace 1TB+ of RAM. Besides, the sensors show no abnormal temperatures on RAM. Anyway, I ordered the optional fans today. I got a hint that airflow maybe suboptimal if only 1 Processor is installed. I'll post if this changes fanspeed behavior (and also if not).

Thanks for your hint!

Hi,

I also found this: http://h20000.www2.hp.com/bc/docs/support/SupportManual/c02157764/c02157764.pdf

There's written on page 12: If one fan fails, all the other fans default to high speed so the server remains within thermal specifications.

But I'm not sure if it's a hardware related problem. When starting the server without booting vmware the fans do not start running at fool speed.

BTW I'm using original HP RAM modules.

Regards,
Bernd

Hi again, just an update:
I installed the optional fan kit. This also didn't do the trick. Since I'm running out of options, so I have to consider replacing all server units. Nice.

I've had the same problem with another type of DL1xx server. I my case an upgrade of the lights out firmware fixed the problem.
So If you only upgraded the bios and not the l.o. give this a try.

Hi wobbe,
thank you for that hint.
The lights out firmware is also up to date. There is a statement in the read-me of the lights-out-firmware saying they solved a problem with fans running at high speed, but it looks there is another prob. also. Even tried with original HP ram now, but still fans go up after 6-12 hours of operation.

I have some ideas left (like hiding network port #1 (Mgmt) to ESXi). I've read something that leads to this direction. Let's see....

Re: DL165 G7 / ESXi 4.1 fans at high speed problem

Finally!

Fans running normal speed, everything's nice now.

After updating ESXi 4.1 with the 2 latest patches to build 320137 system fans run now 48h without going up to full speed.

One thing I did also was setting the mgmt Ethernet port to dedicated and unplugged the cable (on the 165G7 it's port #1), but I doubt that this has to do with it.

IMHO the combination of updating the lights-out firmware to latest release and ESXi to build 320137 is the problem solver.

It's definetly NOT the used ram or the fan option kit.

I wish all reading this a noise reduced 2011 ;-)

Hello Rolf, and every DL165/Esxi Users!
Thanks a lot for your tips.
I'm currently installing new DL165s
I'll try to see if only build 320137 is needed (or also mgmt port or Lights-out) and report here...

Before going in wrong direction... 2 small questions...as DL165+ESXi4.1 is not "officialy" support by HP

You use the VMWare "standard" version : did you use HP Drivers (downloaded from HP Support) like Nic Driver or NMI driver? In these case, did you install them after ESXi install throw CLI?

in production, do you use HP-SIM or other HP management/tool or just plain Esxi?!

Thanks for your help,

HAPPY NEW YEAR to all ;)

Re: DL165 G7 / ESXi 4.1 fans at high speed problem

Hi clyss!

NICs on all of the 1xxG6/G7 Servers I had to setup were recognized without the need for additional drivers.

The only issue I had sometimes was that ESXi-Setup didn't find the internal CD/DVD-Drive and refused to install. I helped myself booting from an USB-Drive there.

At the moment I don't use the HP management tools, so I can't say something about that.

greetings!
