Using VMW_PSP_MRU with ALUA arrays or non-ALUA Active/Passive arrays with ranked paths enables you to set something similar to a preferred path without having to use the VMW_PSP_FIXED plug-in. You may think of this as having multiple preferred paths but with different weights.
VMW_PSP_FIXED --- preferred path
VMW_PSP_MRU --- path rank
