I just checked the OSA-Express Customer Guide and Reference and you are correct, z900 is too old: Beginning with the May 2006 version of Licensed Internal Code on z890, z990 and z9 systems only, this restriction has been lifted. With this version of Licensed Internal Code, a layer 2 host can directly communicate with a layer 3 host sharing the same OSA-Express port. Hardware requirements - z890 or z990 and above only - OSA-Express with Licensed Internal Code level October 2004 or higher - OSA-Express2, all levels - OSA-Express3, all levels - OSD only Alan Altmark z/VM Development IBM Endicott
