I didn't last time I tried, 2 years ago. Anyway this method is not the way to go. You have only two choices here for real multipath handling : 1) You need commercial support, and you don't mind tainting your kernel, then SecurePath is the way to go 2) You are satisfied with community support, then lk2.6 & device-mapper multipath target & multipath-tools are the way to go. Note that you also inherit the risks of being an early adopter. Other solutions just don't fit the availability and care-free criteria. regards, cvaroqui
