解法：
ibm官網給的指令直接照用，不需修改
詳見http://www-01.ibm.com/support/docview.wss?uid=swg21291083
說是AIO裝置沒啟用（not having Asynchronous IO (AIO) device enabled (loaded) in the server.）......
設定完需重啟server

root@p550/home/root>/usr/sbin/chdev -l aio0 -a autoconfig=available
aio0 changed
root@p550/home/root>/usr/sbin/mkdev -l aio0
aio0 Available
