======Manually trigger creation======

We are looking to trigger the recreation of the <code>/etc/udev/rules.d/70-persistent-net.rules</code> file under RHEL 6.5 (current patches)

QUOTE FROM ARTICLE ABOVE:

 Resolution
 •You can manually force udev to create the rules file by running the following command:

This command is recommended to trigger the rules file:

<code># udevadm trigger --subsystem-match=net</code>


Usually the <code>/etc/udev/rules.d/70-persistent-net.rules</code> file can simply be deleted and it'll be regenerated upon reboot. But sometimes it's not or not fully regenerated. In these cases you can try either of these:
<code> udevadm trigger
 udevadm trigger --action=add </code>
For me on an Ubuntu Precise (12.04.1) system the reboot created an entry in the rules file only for one of the NICs. 
And the <code>udevadm trigger</code> did not recreate the rules file. However the <code>udevadm trigger --action=change</code> command did the trick: <code>/etc/udev/rules.d/70-persistent-net.rules</code> was regenerated and it contained entries for both NICs.

P.S.: the <code>udevadm trigger --action=change</code> trick should be used only after you deleted the rules file and rebooted.

Thanks
