Complete the following steps to finalize the CN1610 switches migration to Nexus 3232C switches.
-
Revert all of the migrated cluster interconnect LIFs that were originally connected to C1 on all of the nodes:
network interface revert -server cluster -lif lif-nameShow example
You must migrate each LIF individually as shown in the following example:
cluster::*> network interface revert -vserver cluster -lif n1_clus1 cluster::*> network interface revert -vserver cluster -lif n1_clus4 cluster::*> network interface revert -vserver cluster -lif n2_clus1 cluster::*> network interface revert -vserver cluster -lif n2_clus4
-
Verify that the interface is now home:
network interface show -role clusterShow example
The following example shows the status of cluster interconnect interfaces is

Verify the connectivity of the remote cluster interfaces:
You can use the network interface check cluster-connectivity command to start an accessibility check for cluster connectivity and then display the details:
network interface check cluster-connectivity start and network interface check cluster-connectivity show
cluster1::*> network interface check cluster-connectivity start
NOTE: Wait for a number of seconds before running the show command to display the details.
cluster1::*> network interface check cluster-connectivity show

For all ONTAP releases, you can also use the cluster ping-cluster -node <name> command to check the connectivity:
cluster ping-cluster -node <name>

system cluster-switch showShow example
The following examples show nodes n3 and n4 with 40 GbE cluster ports connected to ports e1/7 and e1/8, respectively, on both the Nexus 3232C cluster switches. Both nodes are joined to the cluster. The 40 GbE cluster interconnect ports used are e4a and e4e.

Remove the replaced CN1610 switches if they are not automatically removed:
system cluster-switch delete -device switch-nameShow example
You must delete both devices individually as shown in the following example:
cluster::> system cluster-switch delete –device CL1 cluster::> system cluster-switch delete –device CL2
-
Verify that the proper cluster switches are monitored:
system cluster-switch showShow example
The following example shows cluster switches C1 and C2 are being monitored:
