Mpathadm reports 4 paths to each lun.
This is very interesting. You are saying that 'mpathadm list lu' produces 'Total Path Count: 4' and 'Operational Path Count: 4'? Do you have four FC connections between the server and the array? What text is output from 'mpathadm show lu' for one of the LUNs? > Suggestions on where I might have messed up?? Perhaps not at all. The approach used in my white paper is based on suppositions from my self since Sun has not offered any architectural documentation on the 2540 or the internal workings of MPxIO. If you do have four FC connections it may be that MPxIO works differently and the trick I exploited is not valid.
