Configuring an active/passive chained replication
To configure an active/passive chained replication topology:
Procedure
When you create the replication link from A to B, select the tenants, namespaces, and directories you want to replicate. In this link, A is the primary system and B is the replica.
When you create the replication link from B to C, select the link from A to B to be included in that link. This causes the HCP tenants, namespaces, and directories replicated on the link from A to B to be replicated again from B to C.
In this link, B is the primary system and C is the replica.The link from B to C can also include tenants, namespaces, and directories that were originally created on B.You cannot individually select the replicated tenants, namespaces, and directories on B for inclusion in the link from B to C.In an active/passive chained replication topology with the configuration , B is the replica for the link from A to B. Therefore, in B, the tenants and directories that were replicated from A are read-only, even though B is also the primary system for the link from B to C.HCP supports replication chains that consist of three HCP systems. Longer chains are not supported.Note- You can also create a chained replication topology in which the first link is active/active and the second link is active/passive. You cannot, however, create a chained replication topology in which the first link is active/passive and the second link is active/active or in which both links are active/active.
- In a replication chain , in which the objects in a namespace on system B are supposed to be metadata-only, HCP does not remove data from those objects until that data has been replicated to system C.
