Hi!
After you install the UI, the first time to add a host, the system will update to include any configured DSA's on that system. After that, you will need to use the UI to make updates if you want to keep the host and the UI in sync. Subsequent changes to the file configuration after the initial add, will not reflect back in the UI. We have an enhancement request to support bi-directional sync of config and it's currently still under review in our backlog.
thanks,
Rob
