Issue

When running "multipath -ll" command, we could see the following output. so, we have questions regarding ordering of multipath devices by "multipath -ll" command.

        # Skip LUNZ device from VNX
        device {
                vendor "DGC"
                product "LUNZ"
        }
}
devices {
        device {
                vendor  "*"
                product "*"
                no_path_retry  fail
        }
}

How does "multipath -ll" command determine the priority of displaying devices? and Can we adjust the priority of displaying devices shown by "multipath -ll"?
