How can I do this ? To enable mpxio, you need to have mpxio-disable="no"; in your fp.conf file. You should run /usr/sbin/stmsboot -e to make this happen. If you *must* edit that file by hand, always run /usr/sbin/stmsboot -u afterwards to ensure that your system's MPxIO config is correctly updated. James C.
