I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It seems to me that the Broadcom Gigabit NIC driver is not installed correctly (or not installed).

Try to down the driver and install it.

Hello,

is it a fresh install of RHEL 6? If yes than you are missing the drivers? You can download them under http://www.broadcom.com/support/ethernet_nic/netxtremeii.php

This was working but not well.  We were able to get the card up but it was not communicating well. We had problems with the SAN loosing connectivity with the FC card. This morning we replaced the FC card. all the sfps  removed an four port nic that we no longer needed replaced the fiber patch cords.   When we brought the server back up we could no longer see the two Broadcom on board NICs

Backup ifcfg-eth0 and ifcfg-eth1 in /etc/sysconfig/network-scripts/
and remove them from that directory.
Then re-install broadcom driver again.

1. Download the zip file from broadcom website.

2. Use USB flash key drive transfer to Linux box

3. unzip it
and read the README file.
There is an instruction for installation.

4. Make sure you have gcc install since installation use
make
make install
(the drive file should be Server/Linux/Driver/netxtreme2-6.2.23.tar.gz)
tar zxf netxtreme2-6.2.23.tar.gz

Wait up.

One last thing before you do the whole drill.

Please issue the following command:

grep alias /etc/modprobe.conf   (you may not have this file in RHEL6)

Then issue this

grep alias /etc/modpro*/*

Show me the output and then you can continue with the drivers.

I was looking for

alias eth0 <driver>

Something of that nature.

One strange thing is that it recognizes your interfaces as eth4 and eth5

I don't know where they are coming from but there are no interface files for them.  I wonder what would happen if you create interface files for eth4 and eth5

All you need to do is:
cp ifcfg-eth0 if-cfg-eth4
cp ifcfg-eth0 if-cfg-eth5

And change the HWADDR fields to 00:14:5e:5a:be:93 and 00:14:5e:5a:be:95 respectively.

I don't understand how and from where did eth4 & 5 come.
