Map network ports using ONTAP 9.7 or earlier

Contributors netapp-pcarriga netapp-aoife netapp-martyh

To enable node3 and node4 to communicate with each other in the cluster and with the network after the upgrade, you must confirm that the physical ports are correctly configured with the settings for the intended use, such as cluster, data, and so on.

Before you begin

These steps apply to systems running ONTAP 9.7 or earlier. If you are running ONTAP 9.8 or later, you must use the procedure in Map network ports using ONTAP 9.8 or later.

About this task

You must perform these steps on node3 and node4.

Note The following command examples refer to "node1" because at this stage in the procedure the replacement nodes "node3" and "node4" are actually named "node1" and "node2".
Steps
  1. If your system is running ONTAP 9.8 or later, STOP. You must use the procedure in Map network ports using ONTAP 9.8 or later.

  2. Locate the port and LIF configuration information for node1 and node2 that you recorded in Prepare for upgrade when moving storage, Step 3.

  3. Locate the information for ports, broadcast domains, and IPspaces that you recorded in Prepare for upgrade when moving storage, Step 3.

  4. Make the following changes:

    1. Boot node3 and node4 to the cluster prompt if you have not already done so.

    2. Add the correct ports to the Cluster broadcast domain:

      network port modify -node node_name -port port_name -mtu 9000 -ipspace Cluster

      This example adds Cluster port e1b on “node1”:

      network port modify -node node1 -port e1b -ipspace Cluster -mtu 9000

    3. Migrate the LIFs to the new ports, once for each LIF:

      network interface migrate -vserver vserver_name -lif lif_name -source-node node1 -destination-node node1 -destination-port port_name

      SAN data LIFs can be migrated only when they are offline.

    4. Modify the home port of the Cluster LIFs:

      network interface modify -vserver Cluster -lif lif_name –home-port port_name

    5. Remove the old ports from the Cluster broadcast domain:

      network port broadcast-domain remove-ports -ipspace Cluster -broadcast-domain Cluster -ports node1:port

    6. Display the health state of node3 and node4:

      cluster show -node node1 -fields health

    7. Each cluster LIF must be listening on port 7700. Verify that the cluster LIFs are listening on port 7700:

      ::> network connections listening show -vserver Cluster

      Port 7700 listening on cluster ports is the expected outcome as shown in the following example for a two-node cluster:

      Cluster::> network connections listening show -vserver Cluster
      Vserver Name     Interface Name:Local Port     Protocol/Service
      ---------------- ----------------------------  -------------------
      Node: NodeA
      Cluster          NodeA_clus1:7700               TCP/ctlopcp
      Cluster          NodeA_clus2:7700               TCP/ctlopcp
      Node: NodeB
      Cluster          NodeB_clus1:7700               TCP/ctlopcp
      Cluster          NodeB_clus2:7700               TCP/ctlopcp
      4 entries were displayed.
    8. If necessary, for each cluster LIF that is not listening on port 7700, set the administrative status of the LIF to down and then up:

      ::> net int modify -vserver Cluster -lif cluster-lif -status-admin down; net int modify -vserver Cluster -lif cluster-lif -status-admin up

      Repeat substep (g) to verify that the cluster LIF is now listening on port 7700.

  5. Modify the VLAN and ifgrp config to match the new controller physical port layout.

  6. Delete the node1 and node2 ports that no longer exist on node3 and node4 (advanced privilege level):

    network port delete -node node1 -port port_name

  7. Adjust the node-management broadcast domain and migrate the node-management and cluster-management LIFs if necessary:

    1. Display the home port of a LIF:

      network interface show -fields home-node,home-port

    2. Display the broadcast domain containing the port:

      network port broadcast-domain show -ports node_name:port_name

    3. Add or remove ports from broadcast domains as necessary:

      network port broadcast-domain add-ports

      network port broadcast-domain remove-ports

    4. Modify a LIF’s home port if necessary:

      network interface modify -vserver vserver_name -lif lif_name –home-port port_name

  8. Adjust the intercluster broadcast domains and migrate the intercluster LIFs, if necessary, using the commands in Step 7.

  9. Adjust any other broadcast domains and migrate the data LIFs, if necessary, using the commands in Step 7.

  10. Adjust all the LIF failover groups:

    network interface modify -failover-group failover_group -failover-policy failover_policy

    The following command sets the failover policy to broadcast-domain-wide and uses the ports in failover group "fg1" as failover targets for LIF "data1" on "node1":

    network interface modify -vserver node1 -lif data1 -failover-policy broadcast-domain-wide -failover-group fg1

  11. Display node3 and node4 's network port attributes:

    network port show -node node1

After you finish

You have completed mapping the physical ports. To complete the upgrade, go to Perform final upgrade steps in ONTAP 9.7 or earlier.
