system crash

Richard Woolley — Wed, 13 Feb 2002 15:41:41 GMT

Early this morning one of my hpux machines went down. The serviceguard package switched and we dont know why because the package did not write to the log file. /var/adm/syslog/OLDsyslog.log tells me next to nothing and only the following lets me know what happened, this is the last entry in /etc/shutdownlog:

02:38 Wed Feb 13 2002. Reboot after panic: , isr.ior = 0'240001.0'fd7f42f8

any ideas please.

cheers.

Hi Mark,

check the syslog on the other cluster node. If it is somehow related to SG, it will be logged into the syslog file of the other cluster nodes. My guess is the SG did a TOC on the server which went down. I had a similar situation earlier, when we had a freak network problem.

Hope this helps.

to you have a corresponding crash dump in /var/adm/crash/
?
this can be analysed with q4.

Later,
Bill

isr means interupt service routine. Generally these are hardware related.

You might want to check your last tombstone /var/tombstones/ts99 file and see if you get any tips there.

Just a thought,
Rita

>. Reboot after panic: , isr.ior =

Usually this means:
1) Hardware fault or HPMC, check for ts99
2) Someone issued a TOC on the system.
3) ServiceGuard TOC'ed th esystem due to some issue.

For item 3, check OLDsyslog on crashed node, and syslog on node that stayed up.

You could also check the INDEX file for th e dump in /var/adm/crash/*

Hi

Can't remember exactly..but feel that this isr
error occured when one of the memory carrier
failed...just a guess...ts99 could give you th e cause...

Hi,
best way to find out what happened is to analyse dump. You can do that with q4 or send it to hp support.

I thought I posted this once alread, but apparently my post went into the bit bucket. There's a document in the TKB that talks about determining the cause of an isr.ior panic. The document ID is: UXDNKBRC00004522

It is attached for your convenience
