Hi All,

I have Suse linux 9.3 installed on HP DL585 server.
There are 2 on-board NICs, and initially they are shown as eth0 and eth1.
After putting a quad-port NIC card, the on-board NIC names changed to eth4 and eth5. Add-on NICs got eth0 through eth3 names.
I want to change the NIC name from eth4 to eth0, I tried by adding PERSISTENT_NAME='eth0' to scripts in /etc/sysconfig/network/.
When I rebooted or /etc/init.d/network restart, it says
rename from eth4 to eth0 failed, file already exists. something like this.
I tried some other options but in vain.

Please let me know how can I fix this.
Thanks in advance.

1. check the udev rules under /etc/udev/rules.d/70-persistent-net.rules (file name may differ in your distribution). These rules are used to automatically rename interfaces too.

2. It is a known issue with the current Linux kernels that interface name collisions occur, for the persistent names, use either higher numbers (e.g.: eth10, eth11, ...) or even a different prefix (e.g.: peth1, peth2, ... for "persistent"-eth) although this *may* cause issues with programs that rely on this prefix, but these are few.

There has been various discussions over a new set of kernel-supported naming rules in the linux net mailing list... change is coming.

In the mean time, good luck!

Change the scripts under /etc/sysconfig/network-scripts and comment out hardware info.
