How to arrange NIC accordingly ?


I faced this quite troublesome problem recently.
I have a DL380 HP server which has around 10 NIC.
These NIC have been labelled just like the layout below :

[Eth9] [Eth8] [Eth7] [Eth6] |
[Eth5] [Eth4] [Eth3] [Eth2] [Eth1] [Eth0] |

I have no problem on bring it up and make it working, just that
the way the OS (RHEL WS U8) that i used somehow loaded all the NIC wrongly. To put it simply, the OS just change the layout. The current Eth6 become something else, so do the Eth2 etc2...

And i need to tell the OS, so by default when it booting up. It will load perfectly.

So, any idea how can i arrange the cards accordingly ? Did anyone has ever experienced a stituation like this ?

Have a peek at either the /etc/sysconfig/network/devices file or the /etc/modprobe.conf file.
A modprobe entry may contain an alias for a particular device, maybe along with the IO memory information for the NIC device.

The problem could also have to do with HAL. I think that there is a file that hal uses that associated a physical device with the name. Some distro's also have an aliases file used by either HAL or udev to rename network devices. I don't remember the name of the file or it's location. Sorry.

I do not know RHEL, but in Slackware 12 you can set this in /etc/udev/rules.d/network-devices.rules
