апну ка я тему 🙂
что скажете про следующее:

Typically, when configuring a SEA on a VIOS, you would deploy SEA Fail Over to ensure network connectivity was protected in the event of a VIOS failure. However, in this PowerHA environment, the approach is different. SEA FO is not used for the PowerHA network. This way, PowerHA is aware of, and controls, network failure and failover. In this case, there is one SEA for the PowerHA network in each VIOS. If a VIOS fails, the service address moves to the boot adapter served by the redundant VIOS.

т. е. я так понимаю, описаный топикстартером вариант с FO SEA – рекомендуют не применять? или у меня с английским не айс?
