Recovering from an incorrectly configured cluster LIF

Starting with ONTAP 9.8, a cluster cannot be created when the cluster network is cabled to a switch but not all of the ports can reach the other ports.

About this task

In a switched cluster, if a cluster LIF is configured on the wrong port, or if a cluster port is wired into the wrong network, the cluster create command can fail with the following error:

Not all local cluster ports have reachability to one another. 
Use the "network port reachability show -detail" command for more details.

The results of the network port show command might show that several ports are added to the cluster IPspace because they are connected to a port that is configured with a cluster LIF. However, the results of the network port reachability show -detail command reveal which ports are not reachable and from which other ports they cannot be reached.

To recover from an incorrectly configured LIF, perform the following steps:

  1. Reset the home port of the cluster LIF to the correct port:
    > net port modify -home-port
  2. Remove the ports that do not have cluster LIFs configured on them from the cluster broadcast domain:
    > net port broadcast-domain remove-ports
  3. Create the cluster:
    > cluster create

Result

When the cluster creation is completed, the correct configuration is detected and the ports are placed into the correct broadcast domains.
