bus error - core dump after installing PATCH-PHCO_23684

Venu_3 — Thu, 25 Jul 2002 00:50:01 GMT

Hi experts,

I was trying to install patch phco_23684 on HP-UX 9000/813 server, running 10.20. It did a corrupt install and now iam not able to run any of the sw commands (eg. swinstall, swlist, swremove). It gives me a bus error - core dump error.

On doing a what core i got this set of message:

There is a later patch for 10.20 PHCO_25640 replacing this one.

This doesn't help you right now though.

Can you boot into single user mode at all?

If so, I'd try that, then going up one run level at a time.

swinstall wont work until runlevel 2 (I think) when your core networking comes up. Runlevel 2 is also when the sw processes are started.

Before attempting this, try to hup the swagentd daemon.

Also check the depot on your system with a checksum and compare it to the patch notes.

You can boot from your previous kernel! Normally like this:
[Reboot]
[ESC] to go into PDC.
Boot Admin> boot pri isl
Interact with the IPL? y
ISL> hpux -is /stand/vmunix.prev

Gerald, Scott thanx for your reply. One small clarification what do you mean by hup the swagent, 'cuz iam new to this Hp-ux system.

Hi Venu,

Can you check if there is a /var/opt/ifor/nodelock file. Old Software Distributor versions used to have this file. If you have check whether there is a '#' character in the file and remove it if so.

Regards,
Mateja

Hi ,
Before booting from alternate kernel just try to kill the swagentd daemon and start it
#ps -ef|grep swagentd
# root 1980 1 0 Jul 23 ? 0:02 /usr/sbin/swagentd -r
#kill -9 1980
#/sbin/init.d/swagentd start

best of luck

Hi animesh, can you give a detail explain why "Before booting from alternate kernel just try to kill the swagentd daemon and start it" ?

With many thanks

Thanx for the reply. Mateja i tried for the nodelock file, there is no such file, and Animesh, i tried to kill and start the swagentd. When doing so, this command

/usr/sbin/swagentd -r gave me a bus error.
