Re: DL380G6 - Position of Temp Sensor 29

Greetings!

 

DL380 G6 server there is no sensor for I/O Board Zone number 13, 14, 15, 27, and 29, but HP Integrated Lights-Out 2 (iLO 2) and the System Management Homepage (SMH) System Information Temperature displays these temperature zones as normal with a zero degree Celsius

 

 I am cheking for more information on this..

Re: DL380G6 - Position of Temp Sensor 29

Renji,

I thank you for your reply.  However, the iLO2 on my server disagrees with you on most of those points.  It does show a temp for 13, 14, 15, and 29.

 

Here is a copy of the iLO2 report straight off of my server:

 Temp 1: Ambient Zone Ok 61F Caution: 106F; Critical:113F
Temp 2: CPU 1 Ok 104F Caution: 180F; Critical:181F
Temp 3: CPU 2 Ok 104F Caution: 180F; Critical:181F
Temp 4: Memory Zone Ok 77F Caution: 189F; Critical:198F
Temp 5: Memory Zone Ok 79F Caution: 189F; Critical:198F
Temp 6: Memory Zone Ok 79F Caution: 189F; Critical:198F
Temp 7: Memory Zone Ok 77F Caution: 189F; Critical:198F
Temp 8: Power Supply Zone Ok 86F Caution: 194F; Critical:203F
Temp 9: Power Supply Zone Ok 77F Caution: 149F; Critical:158F
Temp 10: I/O Board Zone Ok 88F Caution: 194F; Critical:203F
Temp 11: I/O Board Zone Ok 79F Caution: 158F; Critical:167F
Temp 12: I/O Board Zone Ok 86F Caution: 194F; Critical:203F
Temp 13: I/O Board Zone Ok 77F Caution: 158F; Critical:167F
Temp 14: I/O Board Zone Ok 77F Caution: 158F; Critical:167F
Temp 15: I/O Board Zone Ok 77F Caution: 158F; Critical:167F
Temp 16: I/O Board Zone n/a n/a Caution: 158F; Critical:167F
Temp 17: I/O Board Zone n/a n/a Caution: 158F; Critical:167F
Temp 18: I/O Board Zone n/a n/a Caution: 158F; Critical:167F
Temp 19: CPU Zone Ok 70F Caution: 158F; Critical:167F
Temp 20: CPU Zone Ok 75F Caution: 158F; Critical:167F
Temp 21: CPU Zone Ok 77F Caution: 176F; Critical:185F
Temp 22: CPU Zone Ok 75F Caution: 176F; Critical:185F
Temp 23: I/O Board Zone Ok 79F Caution: 171F; Critical:180F
Temp 24: Memory Zone Ok 75F Caution: 158F; Critical:167F
Temp 25: Memory Zone Ok 73F Caution: 158F; Critical:167F
Temp 26: Memory Zone Ok 75F Caution: 158F; Critical:167F
Temp 27: I/O Board Zone n/a n/a Caution: 158F; Critical:167F
Temp 28: I/O Board Zone n/a n/a Caution: 158F; Critical:167F
Temp 29: System Zone Ok 120F Caution: 140F; Critical:149F
Temp 30: I/O Board Zone Ok 115F Caution: 230F; Critical:239F  

 

 

If there is in fact no temp sensor 29 and iLO2 is reporting a non 0c value for that sensor, will a patch or update be released?

Also, sensor 29 is not listed as I/O Board zone, it is listed as "System Zone"

Yes you are correct. The iLO 2 System Information Temperature with P62 System ROM version 05/05/2011 will display this.

 

This is a reporting issue only and does not affect the operation or functionality of the system.

 

Below are few  customer advisories for this issue:

 I hope you find this information helpful.

Re: DL380G6 - Position of Temp Sensor 29

Again, I thank you for your reply, but the information you are providing does not match the behavior I am seeing.

 

You say that there is no temp sensor for 13, 14, 15, and 29, and the advisories you sent say the same thing.  Additionally the advisories say that the temp will be reported as 0c or n/a.

 

However the behavior I observe does not match this.  My DL380G6 reports NON 0c values for 13,14,15, and 29.  i.e. those sensors report what appears to be real data.  In addition the value of sensor 29 fluxuates in an upward direction.  I have posted the temp values reported by iLO2 in this thread which demonstrates this.

 

This DOES cause issues with the system.  When sensor 29 fluxuates to a higher temperature, this causes iLO2 to ramp the speed of the system fans up in an attempt to reduce the reading on sensor 29.  If there is no sensor 29, then this is a bug in iL02 as iLO2 is trying to perform cooling on a component that does not exist.  If this sensor trully does not exist, then iLO2 will never be able to cool it, and the fans will continue to ramp up with no mechanism for them to reduce their speed.  This is going to cause premature wear on the system for no reason.

 

I have posted data directly from iLO2 early in the thread and can provide additional details or screen shots if requested.

 

Sensors 13, 14, 15 remain at a constant 25c.

However, sensor 29 started at 43c and over the last 4 days has climbed to 49c.  The server has essentially been idle for the duration of these 4 days.

 

If these sensors do not exist why does iLO2 report NON 0c values for them?

 

Thank you

Torsten.

Re: DL380G6 - Position of Temp Sensor 29

There were several problems with firmware/BIOS in the past. I would first update to BIOS 2013.07.02  and ILO 2.25 and check if this helps.

 

BIOS:

h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=3884088&swItemId=MTX_9e620e12514142318ed0798627&swEnvOid=4064

Hope this helps!

Torsten.

Re: DL380G6 - Position of Temp Sensor 29

I thank you for your reply.  The server is on the latest versions for all firmware, drivers, software, etc...  It is already running  BIOS 2013.07.02 and iLo 2.25

 

 

Additionally, the HP advisories contradict each other.  Advisory c02070688 dated  2010-05-12 says those sensors are not in place and will report 0c for their temps.

However the other advisory sent to me, c03659941 dated 2013-02-04, plainly shows an iLO2 readout wherein sensors 13, 14, 15, and 29 are reporting non 0c values.

 

So the older advisory says they are not there and will report 0c.  The newer advisory does not talk about them specifically, but does in fact show sensor data for sensors 13, 14, 15, and 29.

 

Either there is NOT a sensor 29 in dl380g6 machines and iLO2 has a bug that causes it to report non 0c values -OR- there is a sensor 29.  

 

If there is a sensor 29 can someone please tell me where it is and/or what it is measuring.   If there is not a sensor 29, is HP going to release a fixed version of ilo2 that addresses this?

Re: DL380G6 - Position of Temp Sensor 29

I'm seeing the same issue as well and i've upgraded all the firmware.  Mine typically sits between 49c-51c

Re: DL380G6 - Position of Temp Sensor 29

Sensor 29 is now up to 52c.   There has been no change in ambient air temp or load on the server.  I have installed the latest iLO2 firmware 2.27 as well (this made no change)

 

This sensor must obviously exist.  Any news on where it is located?

Re: DL380G6 - Position of Temp Sensor 29

Im also having this same issue.  Sensor 29 is currently reading 61C and is in a failed state.  This is causing my system to shut down to protect itself.

Re: DL380G6 - Position of Temp Sensor 29

Hi,

 

We have the same issue with sensor 29.. 

when the system starts ..is set to degraded..in the temperature panel is 207 C...and it seems that the server is overheating on the back (the metal case is more than 40C);

 

What could be?

Re: DL380G6 - Position of Temp Sensor 29

Here the same issue.

right after boot the temperature is going to 52 celsius.

the fans wil run at 78%

the inlet ambiant is 17 celsius.

 

i am unable to let the server running since i live near my office and can't sleep with the high fans.

i need a fix to slow down the fans real quick (i am afraid i need it with in a hour)

Re: DL380G6 - Position of Temp Sensor 29

i think i find the solution.

At the previouse location there was only one power cable availible.

so i unpluged the second power supply and everything worked fine.

on the new location there are 2 power groups availible and i was using the second power supply.

 

now i removed the second power supply (near the middle of the server) and everything is running normal again.

 temp 29 is now reporting 0c and my fans are all low (13%)

 

/edit

15 minutes later.

problem isn't solved

run a update of ilo. now there is a acutally error message.

2 of the disks are non hp sata disks wich have worked fine. now ilo shows this disk as overheated (bay 5 and 6)

i removed this disks (my testlab is running on this disks so no problem) and now temp29 is showing 35c wich is a normal temperature for disks / disk bay

so lets hope this will solve the issue

Re: DL380G6 - Position of Temp Sensor 29

This appears to be directly related to disks in some way.  I was running 6 x HGST 7K750 2.5" drives.  When running this configuration sensor 29 was reading a high temp and all 6 system fans were running at 78% speed.

Over the past several weeks I have replaced all 6 HGST drives with WD Red 750GB drives.  The instant I replaced the last HGST drive with a WD Red drive sensor 29 dropped from 50c to 35c and my fan speeds dropped from a solid 78% to the following values:  13%, 49%, 49%, 41%, 29%, 29%.

I will update this post if that data changes in a significant way.

summary:  sensor 29 is in some way related to the HDD.

Re: DL380G6 - Position of Temp Sensor 29

AFAIR sensor 28 is for the disks. 4 disks, 4 sensors, 1 sensor number. The highest temp. value is reported.


Hope this helps!

Re: DL380G6 - Position of Temp Sensor 29

Thanks for the reply!

It also appears that, for some disks anyway, that instead of the current temp being reported, the all time high temp is reported.

In my case the current HD temps were always around 23c.  The all-time high temp for the removed drives as reported by the smart storage administrator app was around 50c (which matched what sensor 29 was reporting).

 

 

However, sensor 29 is now reporting 35c, and of the 6 drives in machine, the highest current temp is 26c, and the highest all-time temp is 31c, so it seems as though there is more than just drive temp involved.

Re: DL380G6 - Position of Temp Sensor 29

Has anyone found out anymore information about this.  I am experiencing this same issue.  Temp 29 is always between 45 and 50 and the fans will spin up to 78% and sit normail at about 34-36%

Re: DL380G6 - Position of Temp Sensor 29

cmgj,

Sensor 29 represents drive temp.  As I stated in a previous entry, changing the drives caused value reported by sensor 29 to fall which correlated to a drop in fan speed.  It has been many months since I did this and the sensor reading and fan speeds are both low.

If that sensor is reading high (and causing your fans to spin at 78%), then you either need to get your drives cooler, or replace your drives with something that will work better with iLO.  
In my case my drives were not actually hot, but they obviously did not play nicely with iLO.   Replacing them with WD Red drives have solved the issue.

Re: DL380G6 - Position of Temp Sensor 29

I also experienced the same issue with a single HGST drive. Once the drive was removed Temp 29 went from 47 to 35 degrees and the fans spun down to normal speeds. I also found that going from iLo firmware 2.02 to 2.29 also caused a reduction in fan speed. I have yet to see temp 29 change from the 35 degree reading but will monitor it to determine if it remains static.

Update 8/6/2016

Temp 29 has not moved from 35c since the removal of the drive.  I have to believe that this is an unused variable that is hijacked in some way by the HGST drive. This server is not in a controlled environment and other temp sensors have changed in accordance with ambient temperature.

Currently this server has 3 SAS drives in a RAID5 configuration and a single SATA SSD.

Also, it has now been over a year and my fan speeds have not moved at all from what I reported upon placing the WD Red drives into the server.

Re: DL380G6 - Position of Temp Sensor 29

Do we have any information on what specific SMART parameters drive the sensor 29 value?  There are now several large capacity 2.5" hard drives on the market, and I think some of those manufacturers (specifically Seagate) may have a vested interst in fixing this in their own firmware, given the large number of SFF servers in circulation.

I'm trying to work with their tech support to see if they are willing to explore a firmware update.

Re: DL380G6 - Position of Temp Sensor 29

I have been fighting with this for a bit with a pair of Seagate drives. When the drives are in the temp ramps up and so do the fans, if I use the HP SPP diagnostics it actually shows the disk temps as low 20C and the HP SAS disks as 48-49C. Fans fire up and stay at 78%. You take the Seagate disks out and the system behaves normally again. However the HP SAS disks are still showing the high temperature. I have put in a WD Blue and this did not show the same behaviour with the fans ramping up. Here is a good article on the subject http://dascomputerconsultants.com/HPCompaqServerDrives.htm It would be nice if HP could do something about this as a lot of this kit is being bought for home labs and we just don't have the income to pay the HP disk prices.
