Why does PowerHA support often come out after the hardware or software announce?
PowerHA tests all new hardware and software in an PowerHA environment prior to announcing support. We do this because PowerHA exercises features and interfaces in unique and stressful ways which may not be exposed outside of an PowerHA environment. We don’t simply assume new hardware or software works—we bring it into our lab and run it through a qualification test. Sometimes problems are found or take time to resolve which means PowerHA cannot announce support at the same time as the hardware is announced.
