Note that you should also set the IOPS per path to 1 (default is 1000), there is some debate as to whether you should do this or not, HP recommend it for their SAN's, though some worry about the overhead on the ESX caused by switching paths for every IO. The choice is yours, though for further reading and how to do it...
