Server fans going 100%.

Hello there,

I came in this morning and our server fans are going 100% - this has never happened before, and of course our network manager has gone on his holiday;  thus I'm slightly concerned of the implications of this.

I have checked the system logs/event logs and all appears to be working fine.  The server is our main AD server;  clients can login fine, nothing seems to be wrong with the network.

Any ideas why suddenly the server's fans are running a lot faster/louder.  Of course, one would think this is a heat issue;  but as expressed nothing has changed in the server room.  And the server was fine on Friday.

Thanks.

Maybe one of the fans has failed and the others are taking up the slack.  Maybe a temperature sensor has failed.

Maybe the iLO (on HP), DRAC (on Dell) has crashed and needs reflashed again.

What server make/model is this?

Check the CPU usage make sure its not at 100%. Do you have any monitoring agents installed on the server that report issues?

Hello.

The server is a Dell PowerEdge 1800.

All fans appear to be working;  I can feel air from the small top two.  

It is the main fan, at the back grill, that is going 100%.  I cannot hear or tell if the CPU fan is at 100%.  This sever is server around 500+ users, so I dare not move and or investigate further, e.g. take of the cover until tonight.

Thanks.

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Could also be because the case is open. Many servers have a switch that checks whether the cover is on or not. If that switch detects "no cover", the fans will run at full speed. Possibly that switch isn't properly working or not correctly attached to the mainboard anymore...

Also, here in large parts of Europe we are currently experiencing heat days. Maybe the air-conditioning in your server room isn't cooling enough...

Try logging in to the BMC/DRAC controller to see what RPM the fans are running and the temperature of the system.

You may need to reflash/update the firmware for these components.

Is this the only AD server in your company?  If configured correctly, your AD should tolerate a reboot of this server, as long as there are additional AD servers available

Do You have Dell OpenManage installed on the server?

Is air conditioning working fine?

check the server to see if DELL Open Manager is installed if it is then run the program you will probably need a password for access but your IT Manager should have provided senior management with a list seeing that he is absent.

If it isn't installed then go here: http://en.community.dell.com/techcenter/systems-management/w/wiki/1968.dell-openmanage-downloads-explained.aspx

The Open Manager will list all internal components and you will be able to see if there are any alerts that need to be resolved.  I suspect that one or more of the fans are failing which is causing the others to take the strain.

HTH.

Hello, thanks for all the suggestions.

The front bezel has been removed to provide easy access to the power switch/reset button.  But that is it.  The server is located in the UK.  Air con is working as normal.  Open Manager is not currently installed.


Are there any reported cases of Open Manager causing stability issues with Windows Server 2008.   We have lots of summer students currently logged in;  I cannot afford to install software that "could" cause stability issues.  Then again, I cannot afford to ignore this problems as, for example, it could be a CPU fan issue; thus the entire server could go down if I ignore.   Does the software require a reboot to install correctly.  I can reboot at the end of the working day after all the students have gone.

In your opinion, I should install the software to check on the server components?  

Thanks.

To get an accurate answer unless immediately obvious you will need some kind of monitoring software. Are there any warning lights on the front of the server?

Hello.

Yes, just had a quick look; there is a amber warning light flashing on the front.

Just having a quick look here;

Can you access the BMC to view the error codes?

Maybe this can help

I dont remember, if Dell Open Manage needs to be restarted, but I recomend install this tool for future server administration. You can also check RAID drives health etc.....

Hello.

Was going to attach a picture.   I will certainly install this tool for future reference, but it does appear that the server would need to be restarted.   I'm informed that the server has not been restarted for sometime because there has been no need.   The network manager goes away, and this happens.  Typical!

I do not want to restart, just in case;  Its the most important time of the school year whereby exam results are being processed thus we need a working DC.

Install Open Manage Server administrator, select the default install but also select to install the storage components.

This will tell you exactly what the warring is.

I would check to see if the Palida Narrow font was installed, too.

Hi guys; a little update.  The server is still functioning as normal.   Turns out the server is not a Dell but a custom made server which has been provided to us via a company that supplies all the IT related hardware.   I'm currently getting some information regarding the system board.   Thus I cannot use the Dell software.  When I have a better idea of the system components, then I will report back.

rindiCommented:
Maybe you should also get in touch with that company and ask them for their ideas?

Yes, I am;  been on the phone to the local education department and the IT company, they have given me the board ID and apparently have some software that can be installed without rebooting the server.   This is the most important week for the college as exam data needs to be processed which determines funding for the next year.  So I really do not want to have to reboot the system or have it go down.  Why the network manager decided to go on holiday at this crucial time is beyond me!

Will update when I know more.

Update:  Have managed to run some software that has discribed the fault.  

I shall post the results of the diagnostics soon as I have time.

Hello guys;

Here is an image showing the results of the Selview diagnostics.  If you could have a look at the highlighted section.

If you could explain what the 475 issue is, as well; that would be great.

Thanks.

That has to do with what I had mentioned earlier, the switch which checks whether the case is open or not.If the case is opened and the server is running, the state of this switch is recorded. After that you get a message that the case was open during operation. Normally those logs can be reset via a BIOS utility.
