Thank you for the kind words!  On my system, the following is the output.
Notice that the "undef" state is printed as "DM state" of the device. Maybe,
your version of multipath tool doesn't print if it is "undef"

create: mpath3 (320000004cf311021)  IBM-ESXS,ST318453FC    
[size=17G][features=0][hwhandler=0]
\_ round-robin 0 [prio=1][undef]
 \_ 0:0:4:0 sde 8:64  [undef][ready]
\_ round-robin 0 [prio=1][undef]
 \_ 0:0:9:0 sdj 8:144 [undef][ready]
