 sanity test_432: @@@@@@ FAIL: mgs and active  mismatch, 10 attempts

wait_nm_sync() in test-framework.sh uses the IP address as an argument to do_node() :

        # wait up to 10 seconds for other servers to sync with mgs
        for i in $(seq 1 10); do
                for node in $(all_server_nodes); do
                        local node_ip=$(host_nids_address $node $NETTYPE |
                                        cut -d' ' -f1)

                        is_sync=true
                        if [ -z "$value" ]; then
                                [ $node_ip == $mgs_ip ] && continue
                        fi

                        out2=$(do_node $node_ip $LCTL get_param $opt \
                               nodemap.$proc_param 2>/dev/null)
                        echo "On $node ${node_ip}, ${proc_param} = $out2"
                        [ "$out1" != "$out2" ] && is_sync=false && break
                done
                $is_sync && break
                sleep 1
        done

If do_node resolves to pdsh (likely?) then this will not work with IPv6 because pdsh mis-interprets the ':' in an IPv6 address as specifying an rcmd type:

A list of hosts may also be preceded by ... "rcmd_type:" to specify an alternate rcmd connection type for these hosts.
