That looks better! Seems like device-mapper multipath is configuring 
these OK now. You might want to just check that mpp is fully disabled 
if you're going with device-mapper (and also test some cable-pulls to 
make sure the RDAC failover happens properly) but this is certainly 
picking up your hw handler configuration now.
