Enables the reverse replication feature for a replication pair. After reverse replication is enabled for the replication pair, data is replicated from the original secondary disk back to the original primary disk.
Usage notes
- For information about the regions in which async replication is available, see Overview.
- The replication pair for which you want to enable reverse replication must be in the Failovered (
failovered
) state. You can call the FailoverDiskReplicaPair operation to enable failover. - The primary disk must be detached from its associated Elastic Compute Service (ECS) instance and is in the Unattached state. You can call the DetachDisk operation to detach the disk.
- After you enable reverse replication, you must call the StartDiskReplicaPair operation again to activate the replication pair before data can be replicated from the original secondary disk to the original primary disk.
- You can set the ReverseReplicate parameter to false to cancel the Failovered (
failovered
) state and restore the original replication direction.

Type |
Required |
Example |
Description |
Action | String | Yes | ReprotectDiskReplicaPair | The operation that you want to perform. Set the value to ReprotectDiskReplicaPair. |
RegionId | String | Yes | cn-shanghai | The region ID of the secondary disk in the replication pair. You can call the DescribeDiskReplicaPairs operation to query region IDs of secondary disks in replication pairs. Note The reverse replication sub-feature must be enabled from the region where the secondary disk is located. |
ReplicaPairId | String | Yes | pair-cn-dsa**** | The ID of the replication pair. |
ClientToken | String | No | 123e4567-e89b-12d3-a456-42665544**** | 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. |
ReverseReplicate | Boolean | No | true | Specifies whether the reverse replication sub-feature is enabled. Valid values: true and false. Default value: true. |

Description |
403 | OperationDenied | The operation is not allowed. | You cannot perform this operation. |
403 | OperationDenied.InvalidStatus | The operation is not allowed in current status. | You cannot perform this operation on the resource in the current state. |
403 | OperationDenied.NoPairInGroup | The operation is not allowed because no pair in the group. | The operation is not supported because no replication pairs belong to the specified replication pair-consistent group. |
403 | OperationDenied.PairGroupAZoneConflict | The operation is not allowed due to pair and group having different RegionId or ZoneId. | The operation is not supported because the replication pair-consistent group and the replication pair do not belong to the same region and zone. |
403 | OperationDenied.PairGroupStatusConflict | The operation is not allowed due to pair and group status are not consistent. | The operation is not supported because the state of the replication pair is not the same as that of the replication pair-consistent group. |
403 | OperationDenied.PairNotInGroup | The operation is not allowed because pair is not in any group. | The operation is not supported because the specified replication pair has not been added to any replication pair-consistent group. |
403 | OperationDenied.OperateNotAllowedForPrimary | Operation is not allowed on the primary site. | You cannot perform this operation on the primary site. |
403 | OperationDenied.OperateNotAllowedForStandby | Operation is not allowed on the secondary site. | You cannot perform this operation on the secondary site. |
