Difference in CM>PS output

Hi All,

I would request an interpretation of the following PS status. We have 4 servers in a certain site where temperature conditions had gone beyond threshold. 2 of them were shutdown by customer and 2 went down automatically. We have collected the PS output as of now (all systems are power off condition):-

PS
System Power state: Off
Temperature : Med OverTemp

PS
System Power state: Off
Temperature : Med OverTemp

PS
System Power state: Off
Temperature : High OverTemp

PS
System Power state: Off
Temperature : Status is not available

Especially why the last is showing "Status is not available" is the point of concern for the customer.

Will appreciate all inputs.

Thanks in advance

Hi Arkie,
Try reset MP and check again FOR 4th machine

For reseting MP:-

MP> CM Then type XD then R

Thanks

Hi S.M.S.

Did CM>XD>R, but CM>PS is same:-

[mp001560de212b] MP:CM> ps


PS
System Power state: Off
Temperature : Status is not available

Power supplies State
-----------------------------------------------------------
Power Supply 0 Normal
Power Supply 1 Normal


Fans State
-----------------------------------------------------------
Fan 0 (System) Normal
Fan 1 (System) Normal
Fan 2 (Pwr) Normal

Hi Arkie,
It seems temperature sencor is not functional in the system.

What is the system model ??

Arkie,

> Temperature : Status is not available.

This abnormal output seems to be due to over temperature.
You can ask Local onsite person in the Datecener to check the environment and the room temperature. May be there are more issues out there ,

There is nothing much you can do remotely,

Hi Raj

I am the onsite person. You are right in that there was an over-temperature condition (due to AC outage). The customer had powered down 2 of the rp4440's (and 2 others went down automatically before the customer had reached at site).

I checked the CM>PS output and noticed the difference...3 of them showing "Med/High OverTemp", and 1 showing "Status is not available".

Wanted to know the reason...

Re: Difference in CM>PS output

hI Arkie, I suggest you to log a H/W call for this as it is related to temperature sensor and its still not able to measure temperature after reseting the MP

Over temp conditions are critical for any computer equipment and although most HP servers manufactured in the last 10 years will shutdown when the temperature is too high, it still may not protect the server from damage due to high temperatures. You may have a lot more damage that you have not discovered -- things like disk, tape drives, network switches, UPS batteries and electronics.

Your data center needs a critical temperature shutdown sensor, something disconnects power to everything when the temperature exceed 90 deg F (32 deg C). I have personally seen thousands of dollars in damage when the AC goes out and only a few items actually shutdown by themselves. The rest of the equipment is scrap -- unrepairable due to the thermal stress (that never gets better).
