Network fail after reboot

[Hans Ove]

Hi

After the machine have been running with no problem for some months, I was doing an reboot command.

The network FAIL during reboot. See atteched file with console logging.

# model
ia64 hp server rx2660
# uname -a
HP-UX B.11.31 U ia64 (some info removed)

As the files shows, I reconfigure the Lan0 with set_parms. But same problem after reboot...

The /etc/rc.config.d/netconf seems ok, but SAM shows the network as status UP with no ip4 set.

An equal rx2660 machine face the same problem after power loss. Still not able to get it online.


Best regards

Hi Hans Ove,

if not problem show us messages in /var/adm/syslog/syslog.log

I would recommend to run sam and there find network configuration and set up necessary address -- then reboot.

Second to perfom , please disconnect server from switch ( pull out cable from switch and not server) and reboot.
Then pay attention will netowrk interface bring up correctly.

It could be that you have ip address collision in network and during boot up it complains about it and cannot bring up network interface.

Now ip address = 128.1.215.199 ( from your attachment ) is not configured, can you ping it in network, and see is it alive somewhere.

Hope this helps,

Regards,
Elko

please send /var/adm/syslog/syslog.log

and also please check your Lan cable is perfectly connected to the network port and also check you cable on the switch side if connected properly or not.

if still you are facing the same issue than change your lan cable and than try.

if still you are getting the same than please send the output of /etc/rc.config.d/netconf , lanscan , netstat -in


Good Luck

Hi,
One more output to see the /etc/rc.log.
I see that
Configure LAN interfaces ......... FAIL *
So /sbin/init.d/net start fail
Check it to see what's going wrong. Restart it with set -x for example.

Hmm, now the system i working...

Some weeks ago I changed the dst tunable parameter for the kernel. From 2 to 4, without rebooting the os.

This change was now taken in use. When I put it back to 2, reboot, everything ok. I tryed again to set it to 4, reboot, everyting ok.

Sometimes I really don't have a clue whats going on...

Thanks for all contributions.

Best regards
