Linux NIC config

[Duffs]

Hi,

Noticed something very unusual on a BL35p server that I have regarding NIC config. The server fell off the network so I rebooted. After reboot eth1 showed up as connected but the g/w would not respond, eth0 was not configured at /etc/sysconfig/network-scripts/ifcfg-eth0.

I moved ifcfg-eth1 to ifcfg-eth0 and restarted the services but no effect. I then rolled back the change and the g/w responded.

When i checked the server both interfaces (eth0 and eth1) are up and connected – but only ifcfg-eth1 is setup on the server.

Any ideas how this might happen or why?

Rgds,
D.

Shalom,

First when you move ifcfg-eth1 to ifcfg-eth0 you need to change:
DEVICE=eth1

to

DEVICE=eth0

This problem was brought about by either changes to the network configuration of the NIC on the blade complex, or a hardware failure.

The cause of the problem needs to be investigated and corrected.

Your blade complex comes with a bootable DVD that can be used to boot and run hardware diagnostics. I recommend you schedule downtime and do this.
