Re: Thermal monitoring in HP-UX

Connect to the MP of the rp4440. Access the Command Menu with "CM", then request Power State with "PS". Near the top, it will say "Temperature: Normal" if all is well.

If the system is overheating, you will get EMS notifications in the syslog and probably in the MP event log as well. If the system is _critically_ overheating, it will execute a hard shutdown automatically. The overtemp alerting and shutdown is executed by the envd process: see "man envd" for more details.

To view the MP event log, use the "SL" command in the main menu of the MP, select "E" for Event log, then "T" for Text mode. Then keep pressing Enter to see all the log entries.

You won't get a temperature reading from a rp4440, just a Good/NotGood-type indicator.

Hi Shehan

You can check everything from nickel output

#cd /opt/contrib/bin
#./nickel
check the nickel output .

Re: Thermal monitoring in HP-UX

It depends on the server model, some give you a value, some can only give a status (normal/not normal), e.g. a BL860c:

MP:CM> ps


PS
For System Processor Status see the SS command.

For Power Supply and Fan status see the Onboard Administrator.

System Power state : On
System Power usage : 203 Watts
System Power allocation : 255 Watts
Ambient temperature : 24 C
Temperature status : Normal

Over Temperature protection: Enabled



On some models you can get and decode the values from sensors, but this is much more complicated and can't be done from the OS usually.

Hope this helps!

Hi,
[mp-hostname] MP:CM> ps


PS
For System Processor Status see the SS command.

System Power state: On
Temperature : Normal

Power supplies State
-----------------------------------------------------------
Power Supply 1 Normal
Power Supply 2 Fault

Fans State Fans State
-----------------------------------------------------------------------
Fan 1 (Mem) Normal Fan 7 (CPU) Normal
Fan 2 (Mem) Normal Fan 8 (CPU) Normal
Fan 3 (Mem) Normal Fan 9 (I/O) Normal
Fan 4 (Mem) Normal Fan 10 (I/O) Normal
Fan 5 (CPU) Normal Fan 11 (I/O) Normal
Fan 6 (CPU) Normal Fan 12 (I/O) Normal

There is the status Lavel of Temp like normal, critical etc

Teperature in degree not specified..

Re: Thermal monitoring in HP-UX

Keep in mind the server is not a thermometer.

;-)

The server has several sensor to monitor environmental data like temperatures and voltage.

If a value is out of range, the system will alert the operating system.

Some applications are able to access these sensor directly, e.g. the system management homepage on some server models.

Example from my rx2600:

(MP output):

MP:CM> ps


PS
System Power state: On
Temperature : Normal

but SMH output:

Home -> System -> Temperature

Status Sensor Location Temp Threshold
OK Temperature Sensor 216 Ambient Temp 22 38
OK Temperature Sensor 217 Processor 0 Temp 62 103



Try it.


Hope this helps!

Torsten.
