    A Hitch with SEA Failover Testing

    A few months back, I ran into an issue during shared Ethernet adapter (SEA) failover testing. After upgrading to VIO server 2.2.5.10, we would fail VIOS1 and verify our disks and networks were functioning as expected on the VIO clients. Then we'd bring VIOS1 back online and fail VIOS2.
