Installing FAS2240 as single-node cDOT requires private cluster network ports

Hi,

I am setting up a FAS2240 as a single node Clustered ONTAP system. Since this is a single node system, I am assuming that there is no need for dedicated cluster network ports (eg. I am gathering this from this document https://library.netapp.com/ecm/ecm_download_file/ECMP1139842 page 8 and this document https://library.netapp.com/ecm/ecm_download_file/ECMP1157167pages 2 and 3 where the doc mentions you should be providing cluster network ports if you're transitioning from a single node to a 2-node setup (so I am assuming they are not required for a single node setup)).

However, when I run the cluster setup wizard, it keeps asking me to provide cluster network ports:

(cluster setup)

Welcome to the cluster setup wizard.

You can enter the following commands at any time:

"help" or "?" - if you want to have a question clarified,

"back" - if you want to change previously answered questions, and

"exit" or "quit" - if you want to quit the cluster setup wizard.

Any changes you made before quitting will be saved.

You can return to cluster setup at any time by typing "cluster setup".

To accept a default or omit a question, do not enter a value.

Do you want to create a new cluster or join an existing cluster? {create, join}:

create

Step 1 of 5: Create a Cluster

You can type "back", "exit", or "help" at any question.

List the private cluster network ports:

At least one cluster port must be specified.

The cluster network ports are the physical ports on the controller that connect

it to the private cluster network. The controller routes cluster network

traffic over these ports by using associated cluster logical interfaces (LIFS).

Examples of cluster network ports in Data ONTAP are "e0a" and "e0b".

You can type "back", "exit", or "help" at any question.

List the private cluster network ports: e1a

e1a is not a valid port.

etc (there's no mezzanine card in this controller).

I already booten into maintenance mode to change this (since it's not a HA pair):

*> ha-config show

Chassis HA configuration: ha

Controller HA configuration: ha

*> ha-config modify controller non-ha

Controller configuration will change from ha to non-ha.

Warning: Incorrect configuration may lead to data loss. Do you want to continue?? [no] yes

Controller FRU PROM successfully modified to non-ha

*> ha-config modify chassis non-ha

Chassis configuration will change from ha to non-ha.

Warning: Incorrect configuration may lead to data loss. Do you want to continue?? [no] yes

Chassis FRU PROM successfully modified to non-ha

*> ha-config show

Chassis HA configuration: non-ha

Controller HA configuration: non-ha

but to no avail.

How do I go through the setup wizard for a single-controller Clustered ONTAP setup ?

Thanks in advance,

Filip

As it turns out, this node boots into 8.1.2 Clustered ONTAP, so that explains it ... Sorry for the noise.
