Multipath command output - Help with understanding output



Hi,

I've configured multipath but I'm confused with the following. When I
run "multipath -v2" I don't get any output, but if I run "multipath
-v3" I get lot's of output e.g.:

Does that mean multipath is working on /dev/sda and /dev/sdb? Is the
lack of output for "multipath -v2" a concern?

Thanks
