You must verify that the physical ports on node1 map correctly to the physical ports on node3, which will enable node3 to communicate with other nodes in the cluster and with the network after the upgrade.

About this task

Refer to References to link to the Hardware Universe to capture information about the ports on the new nodes. You will use the information later in this section.

Port settings might vary, depending on the model of the nodes. You must make the port and LIF configuration on the original node compatible with the planned use and configuration of the new node. This is because the new node replays the same configuration when it boots, which means that when you boot node3, ONTAP will try to host LIFs on the same ports that were used on node1.

Therefore, if the physical ports on node1 do not map directly to the physical ports on node3, then software configuration changes will be required to restore cluster, management, and network connectivity after the boot. In addition, if the cluster ports on node1 do not directly map to the cluster ports on node3, node3 might not automatically rejoin quorum when it is rebooted until you change the software configuration to host the cluster LIFs on the correct physical ports.

Steps

  1. Record all the node1 cabling information for node1, the ports, broadcast domains, and IPspaces, in the table:

    LIF Node1 ports Node1 IPspaces Node1 broadcast domains Node3 ports Node3 IPspaces Node3 broadcast domains

    Cluster 1

    Cluster 2

    Cluster 3

    Cluster 4

    Node management

    Cluster management

    Data 1

    Data 2

    Data 3

    Data 4

    SAN

    Intercluster port

  2. Record all the cabling information for node3, the ports, broadcast domains, and IPspaces in the table.

  3. Follow these steps to verify if the setup is a two-node switchless cluster:

    1. Set the privilege level to advanced:

      cluster::> set -privilege advanced

    2. Verify if the setup is a two-node switchless cluster:

      cluster::> network options switchless-cluster show

      cluster::*> network options switchless-cluster show

Enable Switchless Cluster: false/true

      The value of this command output must match the physical state of the system.

    3. Return to the administration privilege level:

      cluster::*> set -privilege admin

cluster::>

  4. Follow these steps to place node3 into quorum:

    1. Boot node3. See Install and boot node3 to boot the node if you have not already done so.

    2. Verify that the new cluster ports are in the Cluster broadcast domain:

      network port show -node node -port port -fields broadcast-domain

      The following example shows that port "e0a" is in the Cluster domain on node3:

       cluster::> network port show -node _node3_ -port e0a -fields broadcast-domain

 node       port broadcast-domain
 ---------- ---- ----------------
 node3      e0a  Cluster

    3. If the cluster ports are not in the Cluster broadcast-domain, add them with the following command:

      broadcast-domain add-ports -ipspace Cluster -broadcast-domain Cluster -ports node:port

      This example adds Cluster port "e1b" on node3:

      network port modify -node node3 -port e1b -ipspace Cluster -mtu 9000

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

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

      This example adds Cluster port "e1b" on node4:

      network port modify -node node4 -port e1b -ipspace Cluster -mtu 9000

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

      network interface migrate -vserver Cluster -lif lif_name -source-node node3 -destination-node node3 -destination-port port_name

    6. Modify the home port of the cluster LIFs:

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

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

      network port broadcast-domain remove-ports

      The following command removes port "e0d" on node3:

      network port broadcast-domain remove-ports -ipspace Cluster -broadcast-domain Cluster ‑ports node3:e0d

    8. Verify that node3 has rejoined quorum:

      cluster show -node node3 -fields health

  5. Adjust the broadcast domains hosting your cluster LIFs and node-management/clustermanagement LIFs. Confirm that each broadcast domain contains the correct ports. A port cannot be moved between broadcast domains if it is hosting or is home to a LIF, so you might need to migrate and modify the LIFs as follows:

    1. Display the home port of a LIF:

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

    2. Display the broadcast domain containing this port:

      network port broadcast-domain show -ports node_name:port_name

    3. Add or remove ports from broadcast domains:

      network port broadcast-domain add-ports

      network port broadcast-domain remove-ports

    4. Modify a LIF’s home port:

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

  6. Adjust the broadcast domain membership of network ports used for intercluster LIFs using the same commands shown in Step 5.

  7. Adjust any other broadcast domains and migrate the data LIFs, if necessary, using the same commands shown in Step 5.

  8. If there were any ports on node1 that no longer exist on node3, follow these steps to delete them:

    1. Access the advanced privilege level on either node:

      set -privilege advanced

    2. To delete the ports:

      network port delete -node node_name -port port_name

    3. Return to the admin level:

      set -privilege admin

  9. 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 node3:

    network interface modify -vserver node3 -lif data1 failover-policy broadcast-domainwide -failover-group fg1

    Refer to References to link to Network Management or the ONTAP 9 Commands: Manual Page Reference for more information.

  10. Verify the changes on node3:

    network port show -node node3

  11. 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.

  12. 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 Step 11 to verify that the cluster LIF is now listening on port 7700.
