Creating an EVS Replication Pair (Deprecated)

Function

This API is used to create an EVS replication pair using a specified production disk and a disaster recovery (DR) disk. The production disk is in the primary AZ, and the DR disk is in the secondary AZ.

This API has been deprecated. For details about how to use this function, see the Storage Disaster Recovery Service API Reference.

Constraints

• Two EVS disks used to create the EVS replication pair have been created and belong to different AZs.
• The types and capacities of the two EVS disks must be consistent.
• If the DR disk has been attached to a server, the server must be stopped.

URI

• URI format

  POST /v2/{project_id}/os-vendor-replications

• Parameter description

  Parameter	Mandatory	Description
  project_id	Yes	Specifies the project ID.

Request

• Parameter description

  Parameter	Mandatory	Type	Description
  replication	Yes	Object	Specifies the replication pair creation marker. For details, see Parameters in the replication field.

• Parameters in the replication field

  Parameter	Mandatory	Type	Description
  name	No	String	Specifies the name of the EVS replication pair. The name can contain a maximum of 255 bytes.
  description	No	String	Specifies the description of the EVS replication pair. The description can contain a maximum of 255 bytes.
  volume_ids	Yes	list	Specifies the IDs of the EVS disks used to create the EVS replication pair.
  priority_station	Yes	String	Specifies the primary AZ of the EVS replication pair, that is, the AZ where the production disk belongs.
  replication_model	Yes	String	Specifies the type of the EVS replication pair. Currently, only type hypermetro is supported.
