Check for a typo where you got the 'et0', that's not a normal name (emX, 
ethX, pXpY and wlanX are the usual).

As for a general comment/guide; make sure you've updated the 
/etc/sysconfig/network-scripts/ifcfg-X files (note the DEVICE="..." and 
HWADDR="..." lines).

Here's a general guide for renaming devices under EL6 (inc. CentOS 6.3, 
which I rename NICs under often without trouble).

I changed the name Option from name="wlan0" to name="eth0". After rebooting centos generates a device called /dev/et0. Both lmgrd and vendor daemon found the host ID. But lmgrd and safetech can't communicate together.
