Server down problem

yyghp — Thu, 02 Dec 2004 11:20:32 GMT

One of our server was down last night, had to reboot to make it work this morning.

Here's what I got from GSP:

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.

Type CR for next entry, - CR for previous entry, Q CR to quit.

I got NO record for the past 2 weeks in the /var/adm/syslog/OLDsyslog.log
( The "syslog.log" has the records for the new start after I reboot it this morning )

How can I know what was going on with the server last night ? and What can I do next ?

Thanks !

Check for board/cell connections. CPU connections. Reseat them.

Also from GSP do a check on poer supplies status. (I think command is ps)

ALERT LEVEL: 13 = System hang detected via timer popping

timer popping is usually a non-serious ignorable message. I've never seen a system hang from this.

Do you have crash save configured?

If so, there may be a crash in /var/adm/crash

If not, set up for the next one.

Change the first variable in /etc/rc.config.d/savecrash to 1

Hi,

Take a look at this doc,

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000072401028

The doc id is KBRC00012411.

/quote/

For the vast majority of cases, that error is a "bogus" error, although it can be somewhat corrected by the latest GSP firmware and latest diagnostics.

Superdomes, Keystones, Matterhorns, N- and L-class machines all seem to have this minor fault at times.

/Endquote/

A crash dump analysis, if you have one may help. Try this doc on how to do a crash dump analysis and forward the same to hp for more help,

Hope this helps.

I agree - think that's somewhat misleading info on the GSP information - I'd look at /etc/shutdown log - if you have crash configured as mentioned before - anything in tombstones? send the ts99 file out for analysis? HTH

If this happens again, apparent hang, consider doing a TOC reboot.

GSP cmd "TC".

This will force a memory dump.
