Is there a way for centos to find new nic card information?

[dwhs]

When I move a hard drive from one server to another the nic card never works.

I found a work around where I delete the nic card file, reboot to get a new file, grab the mac address and paste that into the dns settings.

But I just want to request this as a feature or something maybe to add.

This is always a tricky time when I'm in a hurry and learning to do it caused hours of downtime the first time.

Love CentOS, just a thought.

Thanks,

You need to edit the /etc/udev/rules.d file with a name like persistent-net.rules and remove the old MAC address.
