>but unable to find any hardware problem.

You've checked all of the power supplies and made sure that they are all plugged in securely?

[shabash]

Yes Mp logs showing all hardware fine.

On SMH there are same critical erros giving power supplyies issues.But System health status is ok.

The log repeated every night and giving alert information.

Hi,

Maybe there is no HW problem at all, only the EMS subsystem has some defects. Try the following procedure:

1. stop EMS

# /etc/opt/resmon/lbin/monconfig

and then "k" for Kill

2. remove/rename the file /var/stm/logs/monitor/remindersel.dat

3. start EMS

# /etc/opt/resmon/lbin/monconfig

and then "e" for enable

[shabash]

As service guard is configured so we cannot disable EMS.

Hardware event monitoring watches the system for hardware problems. If
you shut this facility down, the system will no longer be able to alert
you to many hardware problems.
In addition, if ServiceGuard is configured to use hardware event monitoring
to determine the health of your system, then disabling monitoring may cause
it to consider this system as having failed. This will result in a package
failover. Type "h" for help to find out more about the implications of
shutdown on ServiceGuard.
Furthermore, if you have used the Event Monitoring Service (EMS) Graphical
User Interface (GUI) within the System Administration Manager (SAM) to
configure the event monitors, this configuration will not be saved, and no
actual monitoring will take place until hardware event monitoring is
re-enabled and you add the monitoring requests back again using the EMS
GUI. Event monitoring resources show up in the EMS GUI under the resource
class "status".



Are you sure you wish to disable event monitoring?


Any alternate way around?

[Viktor Balogh]

hi shabash,

Please read my above comment carefully. It's not about disabling EMS, it's only about restarting it. Anyway, we also use ServiceGuard and this advice came direct from HP support as we also had some problems with EMS. The monitoring subsystem subsequently sent error messages about a defective power supply failure, which was already changed a month before.

Regards,
Viktor

[shabash]

i have tried to renable it.

but still the problem remain the same.

every night at specific time the error generated.but MP logs not showing any hardware error.

[Viktor Balogh]

You can try this:

1. stop EMS
# /etc/opt/resmon/lbin/monconfig
and then "k" for Kill

2. remove file /var/stm/logs/monitor/remindersel.dat

3. start EMS
# /etc/opt/resmon/lbin/monconfig
and then "e" for enable

Let's see if it works...

Is the event current? Maybe you just need to clear the old issues from EMS. See my reply above..

[Prashanth.D.S]

Hi There,

First things first, this is a old event triggered now i.e., actual issue could have occurred on Aug 30 but alert was written to event.log on Sept 15th..

Also noticed this..

EMS Version.....................: A.04.20
STM Version.....................: NA <=== STM versiion not seen here..

Verify if Support tool Manager was properly installed. If not reinstall the same.

If you are using SFM then check if its installed properly..

Also you may try clearing the FPL and SEL logs from MP that could stop the alerts being triggered.

Best Regards,
Prashanth
