We have just installed HP-UX 11.11 in a new server machine.
At some moment on the boot proccess it seems to be hang (it does not show the login prompt) and after some time, the next message is shown on the console.
********SYSTEM ALERT********
SYSTEM NAME: uninitialized
DATE: 03/23/2004 TIME: 21:50:13
ALERT LEVEL: 5 = Boot possible, enviromental problem exists
REASON FOR ALERT
SOURCE: 6 = platform
SOURCE DETAIL: 1 = cabinet SOURCE ID 0
PROBLEM DETAIL: 1 = inlet overtemp
LEDs: RUN ATTENTION FAULT REMOTE POWER
ON FLASH OFF ON ON
LED State: There was a system interruption that did not take the system down.
Check chassis and console logs for error messages.
0x00E000516100E000 00000000 00000000 - type 0 = Data Field Unused
0x58E008516100E000 00006802 1E15320D - type 11 = Timestamp 03/23/2004 21:50:13
I have read some articles about this error and it├В┬┤s something related to a high temperature on the server, but the room in which the server is located is about 24 ├В┬║C.
I verify the error and exit from the GSP but the login prompt isn├В┬┤t shown anyway.
Then I have two questions...
- What is happening with the "inlet overtemp"?
- What is happening with the login prompt?
Thanks in advan
Solved! Go to Solution.

Re: Problems with console and temperature
As the temperature in the room doesn't seem too high, I'd suggest logging with HP.

Re: Problems with console and temperature
You need to check the temperature of the air going into the system, to compare with the temperature of the air coming out of it. HP (and most manufacturers) publish the number of BTU's each machine should use.
Although your data center averages 24 degrees C, the area immediately near this machine could be significantly higher. I've seen temperature differences of 5 degrees C between adjacent racks. In those cases, a regular room-sized fan is needed to move the air around and mix it more thoroughly. Until you check the temperature of the actual air input of the device, relying on a thermostat in one part of the data center is just not good enough.
The same is true with airflow. Check the volume of air going in, and going out. They should be the same except for very small amounts (due to leakage in the cabinets).
On large systems, such RP8400's and Superdomes, HP offers a free preliminary site survey. I strongly urge you to take advantage of these whenever possible.
Until you get the hardware I mentioned, I recommend you open a call with HP support for the answer to your overtemp question.

Re: Problems with console and temperature
I├В┬┤ll contact HP support for the overtemp problem to look for all the fans working properly.
Now I repeat the question of the console login. As I explain in my original post, the login prompt doesn├В┬┤t appear at the console, but I think all the proccess are working OK. For example, I can make a telnet from other machine on the net without problems and look for all the proccess on the system.
From the console (empty screen) I enter in the GSP, have a look to the error messages (overtemp) and exit (CO) but the login prompt isn├В┬┤t still at the console.
May it be cause of the overtemp message?
If it isn├В┬┤t, which can the problem be?
Thanks

SolutionJust check once again for any error saying fan failure or so...at a bit earlier time than the Over temp notification.
Normally GSP gives a fan failure error mentioning the fan number incase of a fan failure.
This is clearly due to temperatue in the room which has increased above the threshold level..
Login to the server from any of the other client using telnet and try out fuser -ku /dev/console and see whether the login prompt is coming back!!
With best wishes

Re: Problems with console and temperature
There is a known Problem with rp24xx
The speed of the CPU fan reduces suddenly as said by HP. for that Hp is adding a small controller/conductor in series with the CPU-FAN and the CPU-Board.
Hey Pls contact HP for the same
Last week only we had done the sam with our
rp2470.. 2Nos.
You will require one for each CPU if you have SMP.
you will also have to get the downtime for the same which is Nothing but only 1/2 and hour.
