I think you may have missed some steps when installing the subscriber. If CUCN-01 is the publisher, it would need to list (you will need to have added) the CUCN-02 to the server list prior to installing CUCN-02. This is just like in CUCM where before you install the subscriber you need to tell the CUCM publisher that a subscriber is coming by adding it to the server list in the publisher. I don't see CUCM-02 in the server list on CUCM-01, so I assume that you didn't do this.
This means that when you installed CUCN-02, you installed it as a publisher.
So, yes, you will need to reinstall CUCN-02. Here is a link to installing a Unity Connection Cluster, and the link is to installing the subscriber. Look at the section just above the Installing the Subscriber Server part, which is the very last step in installing the Publisher:
