You should check the syslog and root's email account first for any diagnostic related notifications.

First check the /var/adm/syslog/syslog.log

for any error or failure

Hi Kumar,

Normally you would see an "EMS Event Notification" in your syslog incase of any hardware failures. This even will also have a command which you can run to get the details of the hardware failure. Or else, you can check the /var/opt/resmon/log/event.log file.

Hi ,

Suppose the problem will occur today then

# view syslog.log then it will open the file
use ur vi editor skill.
/Aug 13 or
/error or
/failure
search these strings in syslog.log

Check all todays log.
Or
u can grep error or failure in syslog.log

You can also check the system management homepage for any "degraded" items:

Hi,

Actually we are impleementing HP OV operations for server monitoring and i have to do hardware monitoring also. If any specific entries for hardware failures in logfiles, i can sent those events to system admin for trobleshooting.

Kumar

"Normally you would see an "EMS Event Notification" in your syslog"

well...yes...if you actually installed EMS that is.

Shalom,

Those port 2301 services work well for HP-UX.

I like EMS.

Also grep /var/adm/syslog/syslog.log for lbolt

That's a good indicator of disk trouble.

also might want to search for the word "POWERFAILED" in syslog.

dmesg is also useful

THE BEST WAY TO FIND OUT H/W FAILURES:-

Log on to MP/GSP and collect the logs from there:-

Loging MP LAN, then execute the below commands:-
MP IP address

MP>CM

MP:CM>ls --------> lan status

U did not menson which HP-UX box Ur using (Cellboard based)?

MP:CM>sysrev --------> system firmware version

MP:CM>pe ---------> system power option (Cellboard based)

MP:CM>pc ----------> system power option (non cellboard based)

MP:CM>cp ---------> Cabinet Parts
MP:CM>ps ---------> power status

MP:CM> pe

This command controls power enable to a hardware device.

You can also obtain the h/w failures by decoding the chasis codes from the following logs:-

MP>CM>SL(Serial Logs)
MP>CM>fpl(Forward process logs)

hello kumar,

you may check event.log at
path :/var/opt/resmon/log

it will show h/w failure messages if any

Best Luck
