At this verbosity level the command only prints output when it changes something. Since your mpath0 device was already up and running at this point there's no changes to make and -v2 will be silent. If there's nothing using the device then you can try running "multipath -F" to flush all multipath devices then re-running "multipath -v2" - this should re-create the map and print something to the terminal indicating what it's done. > > multipath -ll > mpath0 (3600c0ff000d7ba4f4575b24a01000000) dm-0 HP,MSA2012sa > [size=9.1T][features=1 queue_if_no_path][hwhandler=0][rw] > \_ round-robin 0 [prio=50][active] > \_ 0:0:0:1 sda 8:0 [active][ready] > \_ round-robin 0 [prio=10][enabled] > \_ 1:0:0:2 sdb 8:16 [active][ready] > > Does that mean multipath is working on /dev/sda and /dev/sdb?
