6027-3958 [N] Connection from node in cluster cluster rejected
because IPv6 is used in the local cluster but not enabled in cluster
cluster.
Explanation
A connection request was received from a node in the cluster, which does not enable
IPv6, and at least one node in the local cluster is configured with an IPv6 address (not an
IPv4-mapped one) as its primary address. Since the connecting node may not be able to communicate
with the IPv6 node, it is not permitted to join the cluster.
User response
Enable IPv6 in the joining cluster or change all nodes using IPv6 as their primary
addresses to use IPv4 addresses in the local cluster.
