JDBC URL specify failover server

Hi there!, we have a web application connecting to teradata using JDBC url. To handle, automatic failover I would like to specify failover server in JDBC URL. But I couldn't find any information on what attribute I can use to achieve this. Any help is greatly appreciated.
 
Current URL: jdbc:teradata://primaryserver.xyz.com/database=DB1,TMODE=TERA
 
I am looking for something like below
 
jdbc:teradata://primaryserver.xyz.com/database=DB1,TMODE=TERA secondaryserver.xyz.com/database=DB1,TMODE=TERA
