Deletes a replication pair.


  • The async replication feature is supported in the China (Shanghai), China (Beijing), China (Heyuan), and China (Chengdu) regions.
  • Only replication pairs in the Stopped (stopped), Invalid (invalid), or Recover (recover) state can be deleted. This operation deletes only replication pairs. Primary and secondary disks are retained.
  • To delete a replication pair, you must call this operation in the region where the primary disk is located. After the replication pair is deleted, the functionality limits are lifted from the primary and secondary disks. For example, you can attach the secondary disk, resize the disk, or read data from or write data to the disk.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
