Temat: Wyciszanie HP DL360
Artur Smęt:
A da się wymusić boot serwera z pominięciem błędu o witrakach procesorów? Wyłaczenie termal shutdown nie pomaga, np wyłaczyłbym połowę wiatraków dla procków, zostawiając po jednej turbinie na procesor.
Wyłączenie S3 n płycie dało mi jedynie to, ze obroty wiatraków nie skalują się wraz z temperaturą.
Wycinek z hplog:
ID TYPE LOCATION STATUS REDUNDANT FAN SPEED
1 Var. Speed Processor Zone Normal N/A Low ( 12)
2 Var. Speed System Board Normal N/A Low ( 12)
Podejrzewam że to 12 to sa procenty pełnej mocy witraków.
Co do tresholdów, to zauważyłem, ze z updatem biosu, tresholdy zostały powiększone, ale nie dało to nic z tego co zauważyłem.
Chyba, że temperatura otoczenia jest dla niego za wysoka, nie mam czujnika w szafie, ale postaram się ustalic jaka tam panuje temperatura.
Temperatury są w porządku:
ID TYPE LOCATION STATUS CURRENT THRESHOLD
1 ADM1022 Processor Zone Normal 89F/ 32C 122F/ 50C
2 ADM1022 CPU (1) Normal 89F/ 32C 149F/ 65C
3 ADM1022 I/O Zone Normal 100F/ 38C 132F/ 56C
4 ADM1022 CPU (2) Normal 93F/ 34C 149F/ 65C
Chyba, że jest jakiś soft, o którym nie wiem, a pozwala kontrolowac obroty wentylatorów.
Nie znam takiego. Być może skryptowe składniki cpqhealth, ale szczerze mówiąc nie badałem tego.
Przypuszczam że natrafiłeś na to?
===============
The problem is 'solved'.
Not regarding the noise, because that seems for real to be the low noise level these baby's make.
A HP engineer came onsite and we went through all the items, and the documentation.
The HP documentation on how these fans should work in the G3 is very thin. So thin that they have made an extra IQ (hp internal) document on it. To bad it is not openly shared.
The open documentation of the fans by HP is incomplete as well.
It turns out the normal health driver (HP Proliant advanced management driver) has been included in another larger version called HP proliant ILO advances management driver. This driver can be found back inyour system as cpqasm2.dll. That is why the normal one reports it does not need to be installed.
There is and should by design be no speed change at loading of the health driver. The server at hardware-boot allready start the fans in the lowest possible speed.
This is about 20-30% of the max rpm of the fans. Once you heared the max of these fans it will become evident that the 20-30% speed is actually quite silent compared.
HP was able in my presence to proof that these actually was a driver loaded that regulated the fan speed by software. We did this by making the fans go to high speed in 'hardware mode', and making the OS then load, at transfer of the fan control to software the rpm drops down.
Test:
-Take cover off
-When booting at the Press F9 to enter setup press PAUSE
-The server now is pending boot.
-Block the middle fans and cpu fans with some hard paper (we used cd's in paper covers).
-When the temp now goes up the fans will go to high speed. this is very clear in noise.
remove the blocks.
-Make the os boot.
-The fans will drop when the driver is loaded.
The 380G3 proliant specs say the server makes 51dB of noise.
We still think the servers make allot of noise, but its not a system error.
This only leaves the option to file a generic complaint to HP that the fans are not trimmed back far enough to our feeling related to the present environment temprature. If they can by temprature they should go lower.
But this then would require a design change.

W jakiej wersji zainstalowany jest PSP na OS'ie Twojej maszyny?
