Elastic Compute Service:AddDiskReplicaPair

Last Updated:Mar 22, 2024

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.

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

ParameterTypeRequiredDescriptionExample
RegionIdstringYes

The region ID of the replication pair-consistent group.

cn-beijing
ReplicaGroupIdstringYes

The ID of the replication pair-consistent group.

pg-myreplica****
ReplicaPairIdstringYes

The ID of the replication pair. You can call the DescribeDiskReplicaPairs operation to query the IDs of existing replication pairs.

pair-cn-dsa****
ClientTokenstringNo

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.
