  description	String	Specifies the description of a replication pair.
  replication_model	String	Specifies the replication mode of a replication pair. The default value is hypermetro, indicating synchronous replication.
  status	String	Specifies the status of a replication pair. For details, see Replication Pair Status.
  progress	Integer	Specifies the synchronization progress of a replication pair. Unit: %
  replication_status	String	Specifies the data synchronization status. active: Data has been synchronized. inactive: Data is not synchronized. copying: Data is being synchronized. active-stopped: Data synchronization is stopped.
  attachment	Array of objects	Specifies the device name. For details, see Table 3.
  volume_ids	String	Specifies the ID of the disk used to create a replication pair.
  server_group_id	String	Specifies the ID of a protection group.
  priority_station	String	Specifies the current production site AZ of the protection group containing the replication pair. source: indicates that the current production site AZ is the source_availability_zone value. target: indicates that the current production site AZ is the target_availability_zone value.
  fault_level	String	Specifies the fault level of a replication pair. 0: No fault occurs. 2: The disk of the current production site does not have read/write permissions. In this case, you are advised to perform a failover. 5: The replication link is disconnected. In this case, a failover is not allowed. Contact customer service.
  created_at	String	Specifies the time when a replication pair was created. The default format is as follows: ""yyyy-MM-ddTHH:mm:ss.SSSSSS", for example, 2019-04-01T12:00:00.000000.
  updated_at	String	Specifies the time when a replication pair was updated. The default format is as follows: "yyyy-MM-ddTHH:mm:ss.SSSSSS", for example, 2019-04-01T12:00:00.000000.
  record_metadata	Object	Specifies the SDR data of a replication pair. For details, see Table 4.
  failure_detail	String	Specifies the error code returned only when status of a replication pair is error. For details, see the returned value in Error Codes.

  Table 3 attachment field description

  Parameter	Type	Description
  protected_instance	String	Specifies the ID of the protected instance to which the replication pair is attached.
  device	String	Specifies the device name.

  Table 4 record_metadata field description

  Parameter	Type	Description
  multiattach	Boolean	Specifies whether the disk in a replication pair is a shared disk.
  bootable	Boolean	Specifies whether the disk in a replication pair is a system disk.
  volume_size	Integer	Specifies the size of the disk in a replication pair. Unit: GB
  volume_type	String	Specifies the type of the disk in a replication pair. The value can be SSD, GPSSD, or SAS. SSD: the ultra-high I/O type GPSSD: the general purpose SSD type SAS: the high I/O type
