Chassis Hardware Monitor (Events) INLET_OVERTEMP

Via EMS, my Rp8400 was reporting "The system intake temperature is too high" but it did not tell me what the temperature was at the time the email got generated. I have checked this EVENT #33 on HP's web-site with no luck. I am sure this EMS script knows or is set to go off at some pre-defined temperature. Does anyone know what that is or where I can find out more short of placing a hardware call to HP?

Thanks in advance
PS. I had some AC issues which since has been fixed.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Matthew,

The triggers for these alarms are in the kernel or hardware, not in the
monitor; the monitor is informed that the temperature has reached the
Critical or Emergency level, it is does not determine the levels itself
by checking the temperature level. You'd need to ask someone in the
hardware team to get the threshold temperature for that specific server.

Regards,

Jaime.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Not sure if this works for your model (taken from a similar one):

MP:CM> de

Display status of the selected MP entity (for use by trained personnel only)

B - BPS (Bulk Power Supplies)
U - CLU (Cabinet Utilities: Fans, Intrusion, Clock's etc.)
A - PACI (Partition Console Interface)
G - MP (Management Processor)
P - PM (Power Management)
H - Cell Board Controller (PDHC)
Select device: u

Enter cabinet number (0 or 8): 0

...

Inlet Air Temperature : 26 deg C
Altimeter Status : OK
Operating Altitude : 5000 - 7000 ft (1524m - 2134m)

Hope this helps!

Torsten.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

I got 25 now but don't know what the temp was at the time of no AC.

PS. Do you know at what temp they are designed to shutdown due to over heating?

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Not exactly, need to lookup the specs...

I guess somewhere around 36 to 40 celsius.

Hope this helps!

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

I opened a case with HP because my managers need exact numbers.
1- At what temp the EMS kicked off?
2- At what temp the rp8400 is programmed to shut itself down?

To be honest, I am interested to know too.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

These are the stages:

- overtemp warning
- critical warning
- OS shutdown
- power off

There are only some degrees between, but the numbers are different for different models.

Please come back with your findings.

Hope this helps!
Regards
Torsten.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Like I guess, anything above 35 degrees (or better 30 !) isn't good and critical...

Hope this helps!

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Is there a way to get this info "Inlet Air Temperature : 26 deg C" via command line? I need to chart the temp variations via a cron...that would be really nice

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

No, but you can query the MP logs for overtemp messages.

Try for example:

# cd /var/stm/logs/os
# /usr/sbin/diag/contrib/slview -f fpl.log.00

(the filename fpl.log.00 could be slightly different *.01 or something, have a look)

Hope this helps!

Torsten.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

That was not informative for me. What I was looking for is something simple like the folllowing script that I have which simply check the single-bit-errors and keeps it for me. Here is the simple script:

"/usr/sbin/cstm << EOF
selclass type mem
info ; wait
infolog
EOF
"

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

There is NO simple script like this.

You can only try to connect to the MP and interactively run the command you already did (DE) by script (no idea if this works).

Hope this helps!

Torsten.

Re: Chassis Hardware Monitor (Events) INLET_OVERTEMP

Here is the source:

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c00347912&jumpid=reg_R1002_USEN

As you already know, Maximum Operating Range is from 5º C to 35º C.

No matter what really happens above 35C - you are out of the defined range then, this is the important message.

Hope this helps!
Regards
Torsten.
