I have a dual-port Intel Pro/1000 (82571EB) PCIe card. I've installed in into a Dell PowerEdge 1950 running CentOS 6.2 x64. The card is detected and the kernel module is loaded, but a start-up script is not created in /etc/sysconfig/network-scripts. Manually creating a startup script doesn't help; I get an error about the device not being detected.

Thinking it might be a bad card, I tried another card (same model) and even put it in a different slot. No help. However, the strange thing is that this card works without issue in a PowerEdge 2950. Does anyone have any suggestions? Thanks!

Edit: I see that the device is showing up as "p2p1" in the ip link. I altered my manually created init script and the interface now comes online with an ifup command. I can ping myself too. Working to get it online in the proper VLAN now. I will update this post again with the results.

Edit: Very cool. It's now working! I wish I knew why a) the device name is "p2p1" and b) the OS didn't automatically add the init script? Thanks again for your suggestions!

What were the contents of the ifcfg-ethX file that you created? And what was the exact error that you got? –  Shane Madden Feb 16 '12 at 23:19
    
What is the output of ip link? –  Zoredache Feb 16 '12 at 23:25
    
I've edited the post to include the additional details as requested. Thanks for your help. –  jamieb Feb 17 '12 at 3:57

See this post to read why it's p2p1 - PCI slot 2, port 1. http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming

I don't yet know why the OS didn't automagically add the correct ifcfg file.

Hi you need to remove the file

/etc/udev/rules.d/70-persistent-net.rules

to get detect your network card properly. Also reboot your machine after removal of the file. After rebooting do setup from command line to configure the network, if this also didn't work then you will have to create a file for the each devices / interfaces.

Please refer to the blog.
