     * 2. LOCALAWARE_LOCALPERSISTENT
     * Local node has got the new IPs persisted while it has no idea of other nodes' status.
     * 3. LOCALAWARE_CLUSTERPERSISTENT
     * Local node knows the new IPs has been persisted in cluster domain, but not sure if all other nodes know about the fact yet.
     * Local node would try to guess if the new IPs has been committed in cluster domain in some failure scenarios.
     * 4. CLUSTERACK_CLUSTERPERSISTENT
     * Every node knows the new IPs has been persisted in cluster domain and get the same acknowledgement from others.
     * During next reboot, local node would commit the new IPs directly at this status.
     * 5. LOCAL_SUCCEED (Set after reboot)
     * New IP has taken effect in local node.
     * The whole procedure would be set to SUCCEED when all the nodes' status are set to LOCAL_SUCCEED
     * 6. LOCAL_ROLLBACK (Set after reboot)
     * User could rollback IP conf via boot menu, ipreconfigutil would set this node status.
     * Syssvc would set the last IP reconfiguraiton procedure failure and clean the node status file.
