RHEL 7 restricts use of ethN. Pre-RHEL7, I think by listing the subchannels in the network scripts, RHEL will remove device numbers by issuing cio_ignore at boot for you. For RHEL7 you have to take an extra step of removing it in zipl.conf, as it is included after the installation: cio_ignore=all,!condev rd.znet=qeth,0.0.0f00,0.0.0f01,0.0.0f02,layer2=0,portno=0,portname=foo LANG=en_US.UTF-8" This has nothing to do with the predictable names rule, but it can prevent your network script from starting.

That's not a circumvention, that's the solution to your problem. Unless Red Hat decides to modify their kernels to use the old naming convention, this will continue to be needed until you modify all your scripts to handle the "predictable names."
