The mirror management console is provided only for the individual mirror resources managed by MCCS.
The mirror management console operates independently from the engine logic of MCCS, so during operation, it can collide with MCCS.
The mirror management console informs users of the mirror volume status and the capacity of the mirror in use. You can change the bandwidth and the mirror network addresses in it.
