The redundancy type for output streams in Session Control operating mode. - hotWarm indicates only 1 input stream, primary or secondary, is open at any one time. For multicast streams, primary will be joined initially. The secondary is joined after a failover (the primary will be dropped prior to joining the secondary). - hotHot indicates both the primary and secondary streams are opened at the same time. For multicast streams, both streams are joined immediately. Changes to the redundancy type cannot be made while there are active routes or sessions. All routes and sessions must be deleted prior to changing the redundancy type. Once written, a save must be performed via the apexSaveConfig parameter. @Config(config=yes, reboot=no) @Save(apexSaveConfig, value=2) @File(sdv.ini, type='ini')
