My network interface state shows as DOWN when i run sam utility

[Jeevan_4]

Hi,

I am new to HP-UX. I have HP-UX 11.31 machine where the network interface state is showing as DOWN when i run the sam utility.

System light is blinking red in the front panel of hp-ux machine?

We are not able to connect this machine to network?

Can someone help me in troubleshooting on how to bring back my interface to UP state?

I have reset the lan using landiag utility but still the state is showing as DOWN?

Please help.

I'm assuming through the console you are able to get to the server to see that the interface is down?

My guess is you had some sort of failure, the red blinky lights usually isn't a good sign.

Does ioscan -fnClan show NO_HW for your lan card?

Anything in /etc/shutdownlog?

What does uptime show?

Is it a new machine? Which model?
Check is all the latest HW patch bundles are installed.

When i ran the ioscan command i see the below output :-


# ioscan -fnClan
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
lan 0 0/1/2/0 igelan CLAIMED INTERFACE HP PCI 1000Base-T Core


In /etc/shutdownlog i see as shown below:-

00:55 Tue Aug 7, 2007. Reboot: (by 11iv3!root)

We have recently installed HP-UX 11.31, model - hp 9000 rp3410.

There is a patch PHKL_36010 for Lan drivers on hpux11.31.

Try if it helps

Run "lanadmin -g X", where X is the ppa of the lan interface. The ppa for lan0 is "0", lan1 is "1", etc.

If the Operational Status listed is "down", you have an electrical connectivity issue with the network port. Unplug the cable from your system and plug it into something that is "known good".

Occasionally, folks that are new to HP plug their network drop into the Management Processor lan port. This is to give access only to the system console over the network. The HP-UX os can't access that port. I can't remember what the built-in port is labeled, something like "Core I/O" ...

I hope this is helpful.
