L3000 randomly powering down

Hello,

My L3000 (aka rp5470) powers down every couple days, without any reason, as I can tell.

I reinstalled it 10 days ago in HP-UX 11.11 June 04, but it didn't change.

The PDC version is 33.xx.
I am about to apply PHSS_30632 (PDC 44.12).

According to the system alerts I get on the console (see below), I first thought of an overheat problem.
But now, it is very well cooled and ventilated.

Do you have any input ?

Thanks a lot,
Amedee

Re: L3000 randomly powering down

Hi,
Could you check whether FAN's are rotating and are maintaining proper Air Flow inside. Also if the HeatSink are sitted properly on the processor.
Check processor installation thorughly.
Hope that helps.

Re: L3000 randomly powering down

HI

Looks liek the system is generating a lot of heat, maybe the fan some issue and not giving the required ventilation. It is good to have a look at the fan status on the GSP menu as Ravi had mentioned.

Re: L3000 randomly powering down

It seems a overtem problem.
If you want to be noticed when there is a critical overtemp o fanfail condition edit /etc/envd.conf file and add your customized command in CRIT line.

For example:

...omissis
OVERTEMP_CRIT:y
/usr/bin/mailx -s "$(hostname) Overtemp CRITICAL WARNING!" you@yourdomain &1 >/dev/null

OVERTEMP_EMERG:y
/usr/sbin/reboot -qh

FANFAIL_CRIT:y
/usr/bin/mailx -s "$(hostname) Fanfail CRITICAL WARNING!" you@yourdomain &1 >/dev/null

FANFAIL_EMERG:y
/usr/sbin/reboot -qh
Ubi maior, minor cessat!

Re: L3000 randomly powering down

I suppose it is also possible to have a bad sensor. The L3000 can have two or three power supplies, but it needs two to run. Are you plugging two in to separate sources so there is enough power?
