Thank you for the answer. I proceeded according to the last method and got partial success:

[dbadmin@mariadb-N1 ~]$ mysql -u root -p --execute="SHOW GLOBAL STATUS WHERE Variable_name IN ('wsrep_ready', 'wsrep_cluster_size', 'wsrep_cluster_status', 'wsrep_connected');"
Enter password:
+----------------------+--------------+
| Variable_name        | Value        |
+----------------------+--------------+
| wsrep_cluster_size   | 0            |
| wsrep_cluster_status | Disconnected |
| wsrep_connected      | OFF          |
| wsrep_ready          | OFF          |
+----------------------+--------------+
[dbadmin@mariadb-N1 ~]$ mysql -u root -p --execute="SET GLOBAL wsrep_cluster_address='gcomm://172.20.1.56,172.20.1.57,172.20.1.58';"
Enter password:
ERROR 2013 (HY000) at line 1: Lost connection to MySQL server during query

When I dig into the log I see this:
