Red Hat ES 4 network problem
I have a case open with Dell on this issue, but since they have not yet provided a solution, I figured I would ask here about the problem.
I have a new Dell PowerEdge 2950 with three fibre channel HBAs. I had a problem where the NICs were not visible to Linux, so Dell swapped out the motherboard. Now, I cannot get the machine on our network.
I am trying to set up this server with a static IP address and I have set up the relevant files, but when I reboot, /sbin/ifconfig does not contain the appropriate network parameters (i.e., no IP address, no broadcast address, etc.) for eth0 even though I have configured /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0
I have been working via email with Dell on this for several hours and googling over the past few days without any progress at all. I am wondering if anyone on this forum has any ideas on how to fix this problem.
Thanks,
Stan Horwitz

you are running RHEL related system. First, make sure that your
ethernet cards are being recognized and their drivers loaded:
ifconfig -a
to see if you see all three NICs. Write down their MAC numbers.
You can manually enable one of them if you see any by, say,
ifconfig eth0 192.168.1. netmask 255.255.255.0 ...
If it works, then the problem might be in your configuration files.
Make sure that /etc/sysconfig/network-scripts/ifcfg-eth* are correct:
1) DEVICE=eth0 (or eth1, eth2)
2) ONBOOT=yes
3) IPADDR=set correctly
4) NETMASK=set correctly
5) GATEWAY=set
Once they are correct, try 'service network start'. If it still
fails, try
sh -x /etc/init.d/network start
to see where it fails. Good luck!
