With an active/active link, the replication service runs on both HCP systems involved in the link. With an active/passive link, the replication service runs only on the primary system. The replication service starts on the applicable HCP systems or system the first time you add HCP tenants and/or default-namespace directories to a replication link that involves that system.
When you first add HCP tenants and namespaces to a replication link, the replication service immediately replicates the configuration of those items. The service then begins replicating objects in those namespaces and in the selected default-namespace directories. The service starts with the objects with the oldest metadata changes either across all namespaces or within each namespace, depending on the link configuration.
Whenever a new item is added to a replication link or a change is made to the configuration of an item already included in the link, the replication service immediately replicates the configuration of the new item or the configuration change. This ensures the correct behavior of objects on the receiving system.
