Lan card problem

gerjam — Fri, 10 Feb 2006 05:26:57 GMT

Hi HP gurus,

I'm facing a problem now in 2 interface cards of my rp4440 server. The cards can be seen by lanscan command but if I run ifconfig lan2 for example, the system outputs an error message:
"interface:no such inerface". But if i try to plumb the interface manually it works.

I didn't assign any IP address on the interface but I have another server with the same setup and that server can see the lan cards even without IP.

Any ideas? Thank you in advance.

Gerry

Hi,

The default device file for the second card should be lan1 by default.

See from output of

#lanscan
#ioscan -fnC lan
#lanscan (Menu Driven)

HTH,

Hi Gerry,

Check "dmesg" and /var/adm/syslog/syslog.log for any errors. Also, try to configure with "sam".

Can you show us this:

# lanscan
# grep -Ev '^$|^#' /etc/rc.config.d/netconf

I hope if you did not configure ip-address and routing it will make problem.

Hi,

do an IOSCAN

also check if /dev/lan or any ln for lan created or present. In not the system has not initialised than LAN card.

Check with LANSCAN and LANADMIN

Which may require a booting...

Indeed, you will and should get that message until such time as an interface is plumbed. That you have interfaces on other systems without IP's and without error messages from ifconfig suggests to me that something caused them to be plumbed.

That, or the other server is actually running 10.20 which basically did the moral equivalent to a plumb at boot time :)

Shalom goodoph,

I would like to see ioscan output and if this situation continues after a reboot of the system.

Also, note that you can not safely bring up two cards on the same network under HP-UX.

Ex:

192.168.0.10 netmask 255.255.255.0
192.168.0.20 netmask 255.255.255.0

In this scenario 192.168.0 is the network. Bringing up both cards on the same network can cause many bad symptons.

These symptoms include sudden loss of network connectivity.

Hi;

Try to find the detail in log files

#tail -100 /var/adm/syslog/syslog.log
#dmesg |more

#ioscan -funC lan (see the out put)

#lanadmin (check the command carefully)

Cheers
