This is udev playing around with you. You can try to disable its 
net-generator script with something like this:

echo "# disable net-generator rules in /lib/udev" > 
/etc/udev/rules.d/75-persistent-net-generator.rules


Alternatively, you may have more success using BIOSDEVNAME interface 
names.  See 
http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming

You can enable biosdevname in xcat within the bootparams table like so:

chtab nodes=all bootparams.addkcmdline="biosdevname=1"
