Mapping network ports

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

1. Locate the port and LIF configuration information for node1 and node2 that you recorded in 3.
2. Locate the information for ports, broadcast domains, and IPspaces that you recorded in 3.

3. Make the following changes:
   1. Boot node3/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/node4: cluster show -node node1 -fields health
4. Modify the VLAN and ifgrp config to match the new controller physical port layout.
5. Delete the node1/node2 ports that no longer exist on node3/node4 (advanced privilege level): network port delete -node node1 -port port_name
6. 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-portsnetwork port broadcast-domain remove-ports
   4. Modify a LIF’s home port if necessary: network interface modify -vserver vserver -lif lif_name –home-port port_name
7. Adjust the intercluster broadcast domains and migrate the intercluster LIFs, if necessary, using the commands in Step 6.
8. Adjust any other broadcast domains and migrate the data LIFs, if necessary, using the commands in Step 6.
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 node1: network interface modify -vserver node1 -lif data1 -failover-policy broadcast-domain-wide -failover-group fg1
10. Display node3/node4 's network port attributes: network port show -node node1
