Does anyone on the list know of a limit? Can anyone point me to a manual that would document whether this can occur or not? I don't know what WLM uses as a limit, if any, but the I/O hardware has a limit of eight simultaneously active I/O requests to any one given device. Even if you have 100 aliases, there can still only be eight I/Os involving that one device occurring at the same time. These eight can come from eight different LPARs or all from one LPAR. This hardware limit of eight is true whether the PAVs are dynamic or static. I can't quickly find a document with the number eight in it, but it's in patent applications that I have studied.
