I have a new RDS deployment.
We have made the Broker HA.
Attempting to add the second Connection Broker, the role was installed but it reported that it failed, not much else of any use just failure.
As it turns out the Broker role was installed, but not as part of the HA configuration, and it now shows as part of RDS as a connection broker.
Attempting to remove the roles from the RDS deployment (Server Manager) fails responding that it is not part of the deployment.
Question is now how can I force the remove of the server from the deployment scenario sand start again?
I found this, https://support.microsoft.com/en-us/help/2925854/cannot-remove-an-rd-host-from-an-rds-deploymentwhich is of no help as MS want you to call them and I can't exactly do that..
so to sum up: I have an RDS deployment with two brokers, one is in HA mode talking to SQL, adding the second failed but still installed the role but not in HA mode. RDS will not allow me to remove the failed (2nd) server.
