A few other things you wanna make sure of are...
1. that you have a min and max CPU for your VIO that are reasonable values (say 0.2 and 2 with an uncap weight of say 240... actually anything that's at least 30-50% higher than your other partitions so that if they are competing for processing resources, the VIO gets it. The rational behind this is if your VIO doesn't have any resources, none of your partitions can do anything).
2. that you have a number of virtual processor at least equal to your max cpu entitlement (if you have 1 vp and a max cpu of 2, you'll never be able to use more than 1 proc with your VIO).
3. try doing the test by sharing the lun directly to the partition (mkvdev -vdev hdiskX -vadapter vhostX -dev yadiyadiya) AND by sharing a LV to your partition (mkvdev -vdev SomeLV -vadapter vhostX -dev yadiyadiyaLV). If you are currently configured to share a drive that's under a VG and an LV in the VIO, your adding a bit of overhead you don't really need/want in this type of configuration.
Hopefully this can help!
