These scripts are some that I put together to help out with VIPA takeover. I wrote them for my own use, but since there didn't seem to be too many examples out in the wild, I figured I'd let them roam the net a bit.
They're not a "be all, do all" solution. They simply manage the failover from 1 QETH device to another. (If there is a simplier solution available, PLEASE let me know. I just couldn't find one.)
Anyway, take a look at the README file in the distro. It explains everything in more detail.
