IPMI fan speed control on HP DL 360 Ger 7

[Douglas Farias Santana]

Good morning guys,

I own an HP DL360 G7 server and realized that the fans are running in high rotation, even without any intensive processing in progress. I tried to control the speed by ILO 3 in version 1.9.4, but was not successful. Recently, I saw some people managing to control this issue by IMPI.

I used the following command: ipmitool -I lanplus -H 192.168.0.31 -U root -P 12345678 sensor

result :

C:\>ipmitool -I lanplus -H 192.168.0.31 -U root -P 12345678 sensor

Could someone explain to me how I can use the RAW command to change the values of the fans?


ex: ipmitool raw 0x3a 0x01 0 1e 1e 1e 1e 1e --> this does not work on my server

Recently, I saw some people managing to control this issue by IMPI.

for that you need to run IPMI on your servers BMC.

What do you mean ? Can you help me with that?

IPMI must be enabled. but i am not sure the HP IPMI supports raw cmd's

 

[Douglas Farias Santana]

I activated ipmi by ILO

 

[RolloZ170]

i think you have a critical temps/event that enables high RPM of the FANs.

 

[RolloZ170]

what can help:
login to iLO and select "Cold Boot".

where it stays I searched in everything here

pls check under information->overview & ILO Event LOG if there is any unnormal state reported.
information -> system information Summary

 

[RolloZ170]

do you see any warnings/error on BIOS POST screen at startup ?
have you installed a big GPU ?

 

[RolloZ170]

after bringing your HP to normal state you can try IPMI cmds for FAN control.
but afaik this needs a modified Firmware.
what i know is HP and Dell machines turn up FANs if you install a powerfull GPU in it.

I didn’t put GPU only Windows 10 on SSD

this way

 

[RolloZ170]

OK your system is healthy.
FANs at around 45% ist good.
sorry: if it is too loud swap to g8/g9

So there’s no way I can narrow it down?

hundrets tried before. just google it.
i know those g7. its a server for a special room.
you can solder a resistor in the 12V line of the FANs.

I saw that a person put an Arduino to control, I will research about this resistor to see or try to put an Arduino also haha

you must be in love with your dl360
