Adds a replication pair to a replication pair-consistent group.
Operation description
Usage notes
- For information about the regions in which the replication pair-consistent group feature is available, see Overview .
- A replication pair and a replication pair-consistent group replicate in the same direction if they have the same primary region (production region), primary zone (production zone), secondary region (disaster recovery region), and secondary zone (disaster recovery zone). A replication pair can be added only to a replication pair-consistent group that replicates in the same direction as the replication pair.
- Before you can add a replication pair to a replication pair-consistent group, make sure that the pair and the group are in the Created (
created) or Stopped (stopped) state. - Up to 17 replication pairs can be added to a single replication pair-consistent group.
- After replication pairs are added to a replication pair-consistent group, the recovery point objective (RPO) of the group takes effect on the pairs in place of their original RPOs.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| RegionId | string | Yes | The region ID of the replication pair-consistent group. | cn-beijing |
| ReplicaGroupId | string | Yes | The ID of the replication pair-consistent group. | pg-myreplica**** |
| ReplicaPairId | string | Yes | The ID of the replication pair. You can call the DescribeDiskReplicaPairs operation to query the IDs of existing replication pairs. | pair-cn-dsa**** |
| ClientToken | string | No | The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. | 123e4567-e89b-12d3-a456-42665544**** |
