I beleive you mean ha-broker-url option. I set it on both brokers to:

ha-brokers-url=amqp:tcp:qpid1:5672,tcp:qpid2:5672


But still the backup broker stays in joining state:
[radek@qpid1 ~]$  qpid-ha status --all
qpid1:5672 active
qpid2:5672 joining



I don't know if this matters but the master broker show this: 

2014-05-27 13:49:03 [HA] info Primary: New backup connection: 3bc70754(joining)
2014-05-27 13:49:03 [HA] info Membership: 6732b428@tcp:qpid1:5672(active) 3bc70754(catchup)

2014-05-27 13:49:03 [HA] info Membership: 6732b428@tcp:qpid1:5672(active) 3bc70754(ready)

2014-05-27 13:49:03 [HA] info Primary: New backup is ready: 3bc70754(ready)
2014-05-27 13:49:03 [HA] info Primary: Disconnect from backup 3bc70754(joining)
2014-05-27 13:49:03 [HA] info Membership: 6732b428@tcp:qpid1:5672(active) 
2014-05-27 13:49:03 [HA] info Primary: Disconnect from unknown backup 3bc70754(joining)


And the last line indicates that master broker still doesn't know the backup broker for some
reason?

Cheers,
Radek.
