Bug Description

Sometimes the FC attach code doesn't discover the devices under a multipath device due to changes in multipath -l output.
It causes the device to show up in the DB as "/dev/" instead of "/dev/sdb". This causes devices to fail to detach correctly.

    Fix for missing multipath device name

    Due to formatting changes in the multipath -l output
    we were sometimes missing the device name for each of the
    multipath devices which gave us a device of '/dev/'. This
    causes problems on detach.

    Fixes Bug: #1180497
