High temperature issue

Hi Guru's,

Our environment is composed by many HPUX machine (rp5470,l2000 etc...). Tonight due to cooling problem the temperature has growth very much and all the machine have auto-powered off. All the machines except an RP 4440. On syslog no message indicating the temerature issue, but now we have the temperature led turned on and orange. Could someone explain me what happened and how I can turn off that led (we also used GSP command ShowLogs without success)??


Many thanx
AP

Re: High temperature issue

Hi,

'envd' daemon monitors the environmental conditions and takes action according to /etc/envd.conf. However, it does log messages into syslog unless it is configured not to in envd.conf. Check your envd.conf file. It should have 'reboot -hq' associated with emergency conditions.

Re: High temperature issue

hi,

these are the lines into the envd.conf:

OVERTEMP_CRIT:y

OVERTEMP_EMERG:y
/usr/sbin/reboot -qh

FANFAIL_CRIT:y

FANFAIL_EMERG:y
/usr/sbin/reboot -qh


now our issues are two:

1- why this machine has not rebooted while the all others yes(no message appear in syslog)?

2- how to turn off the orange temperature led.

Re: High temperature issue

1. is envd running?

2. the sensor that activates the led may be fried and in need of replacement.

Re: High temperature issue

1. Yes is up and running.


But how is it possible that other machines doesn't rebbot?
Also is there an hp tool for monitoring temperature and sensor status?

Thanx

Re: High temperature issue

The other machines did reboot. The reboot "-h' option powers down the machine to protect it when too hot.

On the rp4440, from GSP try the PS command to see what the current temperature status is.
