But I have to say I see little value in adding this option to multipath. What's wrong with simply running "multipathd list paths format %N %R %n %r", or wrapping that command in a simple shell script? Actually, this has nothing to do with multipath at all, it's really transport-related information similar to "lsscsi -t" output.
