I don't think ASMlib is officially supported with EMC PowerPath. With the new ver. of PowerPath 4.5 I think it might work. Double check with EMC before you proceed. We have several instances of 10G RAC with ASM working with PowerPath not using ASMlib. Mapping with rawdevices and PowerPath works fine. It is very simple to administer and no layers in between.  Raj
