Complete the following steps:

2. Check the controller status by running Get-BrokerController. You will see secondary controller will be partially added to the site

3. Based on the exception in error details, Check the service status by running Get-AcctServiceStatus & will see output as 'OK' however all other services show as 'DBUnconfigured'.
