DL 380 G4 fan control

Recently we bought DL 380 G4 server equipted with 8 redundant fans.

I installed Windows Server 2003 x64 Standart Edition using SmartStart 7.40 CD. Everything seems to run fine except the fans. They are very noisy.

From my past experiences with HP servers I know that fans are controled with cpqhealth driver which is loaded during OS boot. But in this case I can't see the driver loading.

Where can I download and install Compaq Health driver separately? Is it supported by x64 edition of Windows Server 2003?

I searched here on forums but couldn't find solution for my problem.

Visit http://www.hp.com/servers/swdrivers and select your model and download the ProLiant Support Pack and install it. Everything you need is contained in there.

Re: DL 380 G4 fan control

I already installed PSP as I installed operating system with the help of SmartStart CD.

Also to make sure, I checked every driver/software on download page. But fans are still rotating at enormous speeds.

Any other suguestions?

Re: DL 380 G4 fan control

Under system management home page
Recovery /Environmental
What Speed you have for all fans, normal or high (low and full)?

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=PSD_CN0354W

Would be same for G4

What you use for compare? Server? Generation? Newer G3, G4, some of the louder.

Re: DL 380 G4 fan control

Speed is "normal" on all 8 fans.

I have another 4 or 5 servers in same rack. DL320, ML350 and ML370 (all G3). Also one old HP TC and one SuperMicro server. DL380 G4 is louder than all of them in sum.

If fan control would be passed to Health Driver I would knew, because I would hear speed changes, right? In my case *I think* Health Driver is somehow not enabled or not installed.

Re: DL 380 G4 fan control


As a result of this enhancement, when the ProLiant DL380 G3 or G4 server is powered up, the system fans run at normal operating speed and there is no noticeable change in fan speed when the Health Driver loads and fan control is passed from the hardware to the Health Driver (refer to the diagram below).

You can try to slide out server open top cover and monitor system management home page, it might take 7-15 + minutes, in some cases you can try to place piece of paper in the front of CPU zone fans and monitor for sound and speed.

Re: DL 380 G4 fan control

I tried your solution with sheet of paper (and with my own hands also :)) and still can't see, hear or feel any speed change during OS load.

I'm almost sure that something is wrong. Because even 1U DL320 G3 with very small and very noisy fans is A LOT quiter.

Does anyone know if Health driver is supported under Windows Server 2003 *x64* Edition?

Re: DL 380 G4 fan control

SNMP, Server agents and system management Driver you need to have for tools at system management home page and other stuff.

Try to open Version Control Agent form system management home page you can see exactly what installed
You should able see HP ProLiant iLO Advanced and Enhanced System Management Controller Driver .....

Re: DL 380 G4 fan control

What does the 'Environment' link on the Systems Management Homepage (Insight agent) say? Are the fans listed as 'Normal' or something else?

Don't be surprised at the amount of air that needs to be moved through the chassis (which is directly related to fan speed)--the DL380G4 produces almost twice the amount of heat the DL380G3 did, primarily due to the newest processors:

Re: DL 380 G4 fan control

Myself and others noticed this very problem on the DL380G4 in an HP training class in Cupertino. If I remember correctly, we reseated the fans and that fixed the problem.

This symptom only came up after we did some work with cards in the system. We just figured we bumped the fan array loose somehow.

I would reseat that, if that doesn't work, try reseating other components in the system.

Basically, the system thinks that it is not 100% healthy, therefor running the fans to cool itself down (even though it isn't running hot...)

Also, do you have redundant power supples with only one connected?

Re: DL 380 G4 fan control

I tried to reseat fans and cards all morning with no luck.

I have 2 redundant power supplies connected now. However when I turned on the server very first time it was only with one. Why are you asking?

Re: DL 380 G4 fan control

Hi Vilius,

There is one way you can test to make sure the fans are working correctly in your server but you may want to try this when it is not in production or after hours.

Please see the following URL:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00264753

Reduce the fans to only the primary fans. Then pull one of the primary fans to simulate fan failure. The server is smart enough to kick fans into high speed when there is fan failure and no redundant fans are available. You should then notice the fans kick into high speed. If you notice the fans kick into high speed after a few moments, re-insert the fan to restore the system to normal operation.

Let us know if this works for you. There is no risk to doing this so long as you do not leave it running too long at a reduced number of fans, but at least you will know if they kick into a higher speed or not.

Please also note that this server requires almost twice the cooling compared to the previous generation of DL380 server as well and the fans are bound to be a bit nosier.

One last thing I would suggest is to boot to smartstart CD goto the maintenance tab and click server diagnostics. From there you should be able to goto environment and determine the temperature of the system and cpus inside the server and see if they are close to the threshold or not.

Re: DL 380 G4 fan control

Today I tried all possible configurations of fans leaving to run server for about 5 minutes everytime. Fans are not kicking into high speed. And everytime System Management Homepage says that remaining fans are rotating at normal speed.

Is primary only fan configuration redundant? I always thought that redundant are two configurations, but for me Sys Management Homepage redundancy only shows with all 8 fans.

Another note: I noticed that some fans are rotating slower. At first I thought that this sloweness is tided to fan port, but in my suprise it is tided to the fans it self.

Some very strange things happening here.

Re: DL 380 G4 fan control

If you are concerned that the fans are not operating properly I would suggest you calling support at 800-474-6836 and use voice keyword "ProLiant" and speak to an agent about correcting this and making sure that your server is operating correctly.

Re: DL 380 G4 fan control

Vilius, I read through your reply again and I'm not sure if you answered this but did you try my suggestion with bringing the server down to only the primary fans as indicated on the diagram on the URL I linked and pulling a fan briefly to simulate failure?

In the case of a fan failure when there are no redundant fans are installed, the server will perform a graceful shutdown if the health driver is loaded or the condition is detected during POST. The front panel internal LED will turn red. If the fan failure occurs during normal server operation, the remaining fans will ramp up to full speed and the server will continue to operate until a critical condition is reached. At that time, the system will shut down. There is a Thermal Shutdown setting in RBSU that once enabled can ensure an orderly OS shutdown when an OS Shutdown Setting (also known as Temp Caution) is reached.

If you have only the primary fans installed and pull one of them, it brings it down to a failed state and should immediately jump up the speed on the fans. If you find that you do this and there is no change of the speed then most likely your system is always running at full even though SIM reports Normal speeds.

Re: DL 380 G4 fan control

Sorry for my pure English.

Yes I tried your solution.

The red LED came up. But the fans remained in normal mode and speed. Even with 1 fan!
No jumps to high speed, no shutdowns.

Re: DL 380 G4 fan control

Thanks for replying, your fans are definately not working the way they're supposed to. I'd call support as suggested above.

Hi,

I think the fan controller on board might be faulty, try replacing the system board.

Re: DL 380 G4 fan control

Local HP support just replaced the system board. Still the same behaviour. The funny thing is that they were not sure about the fan speed too :). So they decided to test couple machines in their server farm and would tell me about results.

Re: DL 380 G4 fan control

Vilius, 5 minutes could be just not enough to get to critical level
You can safely open top cover and let system run with 5 fans
Before you open System Management Home Page (SMHP) pull one Fan, simulate failure
From SMHP you should notice one fan is missing this need only to test SMHP
Following Steps would not depend if you have fan removed or not, it's up to you to install or keep out

ONE RULE !!! Keep BIOS Settings to default, clear NVRAM Prior you run the test !!!

To speed up simulated Overheating, Keep Top cover Open you can use a piece of Paper to change direct Air Flow
See attachment for exact paper position, red long one can be full high 2U piece of paper and red short should block only partially air flow, so fan can cool itself down.
Let system stand over 15-25 minutes (or less), stay close and Refresh status from SMHP regularly

Re: DL 380 G4 fan control

At last. Thank you KOV. It seems that I misplaced paper sheets the first time, and I didn't cleared NVRAM of course.

I've followed your instructions this time step by step and fans are kicking into high speed. Now I can sleep well as I know that fans are working properly :)

Thanks again!
