A cluster cannot be created when the cluster network is cabled to a switch but not all of the ports configured in the Cluster IPspace can reach the other ports configured in the Cluster IPspace.

About this task

In a switched cluster, if a cluster network interface (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.

Learn more about cluster create in the ONTAP command reference.

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 do not have connectivity to one another.

Learn more about network port show in the ONTAP command reference.

To recover from a cluster LIF configured on a port that is not reachable to the other ports configured with cluster LIFs, perform the following steps:

Steps

  1. Reset the home port of the cluster LIF to the correct port:

    network port modify -home-port

    Learn more about network port modify in the ONTAP command reference.

  2. Remove the ports that do not have cluster LIFs configured on them from the cluster broadcast domain:

    network port broadcast-domain remove-ports

    Learn more about network port broadcast-domain remove-ports in the ONTAP command reference.

  3. Create the cluster:

    cluster create
Result

When you complete the cluster creation, the system detects the correct configuration and places the ports into the correct broadcast domains.
