You enabled Management, vMotion and FT on the same vmkernel port. They all should be on separate kernel ports with in separate ip-ranges and VLAN's. What you are doing is nuts. It goes against just about every rule and best practice.
The Topic Starter is not using vCenter but an ESXi Server GUI directly (which does not have vSAN config-capabilities). Edit the config in vCenter (but first, separate all the vmkernels as I said before. Don't try getting this to work and expect it to run properly).
