Hello,
By design it will continue running if the partnership is connected. Replication can continue during maintenance on the links, although the throughput may degrade, and the system is designed to handle this. You can also apply different replication policies with different RPOs to the volume groups and if the link bandwidth is insufficient then the system will automatically prioritise the volume groups with lower RPOs.
If you want to completely stop replication for a volume group you can make the recovery copy independent (equivalent to stop-with-access for Global Mirror).
