HP 9000 L-Class rebooting at will

Hey guys,
My HP 9000 L-Class keeps rebooting for no apparent reason. I cant figure it out. It
seems to boot like 2 or 3 times in a row...

On December 5th it rebooted 9 TIMES?
Dec 5 00:38:44 acp /sbin/init.d/sendmail[1124]: #### rebooted ####
Dec 5 04:31:50 acp /sbin/init.d/sendmail[1125]: #### rebooted ####
Dec 5 09:04:12 acp /sbin/init.d/sendmail[1126]: #### rebooted ####
Dec 5 10:06:10 acp /sbin/init.d/sendmail[1127]: #### rebooted ####
Dec 5 11:50:03 acp /sbin/init.d/sendmail[1128]: #### rebooted ####
Dec 5 12:16:40 acp /sbin/init.d/sendmail[1129]: #### rebooted ####
Dec 5 13:25:53 acp /sbin/init.d/sendmail[1130]: #### rebooted ####
Dec 5 13:42:46 acp /sbin/init.d/sendmail[1131]: #### rebooted ####
Dec 5 13:52:47 acp /sbin/init.d/sendmail[1132]: #### rebooted ####

Any idea what I can look at to figure out why the machine keeps rebooting.

I look in /etc/rc.log and /etc/rc.log.old and dont see anything good.
I also look in /var/adm/syslog/syslog.log
and OLDsyslog.log - same story....

Is there a way to view the crash / dump info?

Look at /etc/shutdownlog. Also look in /var/adm/crash.

no files in /var/adm/crash
Do I need to turn something on to collect crash data?

and last entry in shutdownlog is Nov 29th.
No entries for the mystery reboots.

What is your settings in /etc/rc.config.d/savecrash ?

If your SAVECORE=1 and SAVECORE_DIR=/var/adm/crash , then it will generate crash dump, if system crashed.

If SAVECORE=0 then change it to 1

Hi Shibin,
Both SAVECRASH and SAVECRASH_DIR were commented out.
They are now:
SAVECRASH=1
SAVECRASH_DIR=/var/adm/crash

I think all other options are also commented out.

By changing /etc/rc.config.d/savecrash do I need to restart the machine to pick up the new options?

No need to reboot system. You can restart these services.

/sbin/init.d/crashconf
/sbin/init.d/savecrash

Re: HP 9000 L-Class rebooting at will

Please check /etc/rc.config.d/crashconf

It should be something like this.

CRASHCONF_READ_FSTAB=1


CRASHCONF_REPLACE=0


Read man pages of crashconf and savecrash for more details :)

Hi Gary,

Take a look in the GSP logs to see if any chassis code events are logged that may lend a clue to the reason for the reboot. Dump out all of the events prior to and after the reboot and post.

Telnet into the GSP and do a control B

^B



GSP> sl


SL

Select Chassis Code Buffer to be displayed:
Incoming, Activity, Error, Current boot or Last boot? (I/A/E/C/L) e
e

Set up filter options on this buffer? (Y/[N])


The first entry is the most recent Chassis Code
Type + CR and CR to go up (back in time),
Type - CR and CR to go down (forward in time),
Type Q/q CR to quit.


Log Entry # 0 :
[]
Type CR for next entry, Q CR to quit.

hi,

as cnb says look at the GSP logs and post the last 6-10 entries if you can

Also in STM look at the pim data for the cpu's, this should tell you if it crashed with a cpu or io error

select cpu in stm and run infolog tool on it
