Re: server suddenly reboot without problem signal

Sam,

You need to look at the OLDsyslog.log, the /etc/shutdownlog, and crash dumps in /var/adm/crash, and any diagnostic logs (assuming you're running diagnostics).

Re: server suddenly reboot without problem signal

Did you check the other logs to see if that's a "proper" reboot or unwanted one.

Re: server suddenly reboot without problem signal

Check the NIC card, cable and switch, it appears that your LAN connection was interupted. This could result in the issues you've noted in this thread.

From the outisde on a Unix/Linux box. ping hostname

If the ping times gradually climb, you need a NIC card replacement.

dmesg

Check for hardware faults.

ioscan, look for NW_HW or unclaimed devices.

Check /var/adm/crash for crash dumps.

If there is one, follow the attached guide to analyze the dump. You may need a patch.

Re: server suddenly reboot without problem signal

What version of MC/SG (MC ServiceGuard cluster software) are you using? Applying these patches might solve your issue:

For HP-UX 11.X, MC/SG version A.11.09 - PHSS_27158:

Re: server suddenly reboot without problem signal

Sam,

Since the last entry I see in your syslog is someone su'ing to root, I have to wonder if this is somehow connected. Do you know who did the su? Do you know what they did after they su'd? What does /etc/shutdownlog say?

Please check for possibles cron jobs that may trigger a reboot.

run

# crontab -l

and check for each of the jobs scheduled.

Thnaks for you all info.

Here is the OLDsyslog.log file. Please help me to see whether the system crash is due to hardware problem or other.

Re: server suddenly reboot without problem signal

Sam,

I don't think we're seeing all of the OLDsyslog.

Could you just do a "tail -100 /var/adm/syslog/OLDsyslog.log" and attach that output?
