Edit Cluster Parameters
                                                            When editing a cluster node, you can only edit the cluster leader preference. You can only change the cluster leader preference on one node at a time.
                                                            For the leader preference, higher values are more likely to claim the Leader and Standby roles; lower values are less likely.
                                                            To edit leader preferences:

                                                            Note:  Most of the fields are read-only. You can change the cluster leader preference, as desired. Use preference settings from 10 to 100 for leader, standby, and member roles. Use preference settings from 1 to 9 for normal nodes that are excluded from taking the leader or standby role. GigaVUE TA Series nodes always have a preference of 1.
