Detaching a Replication Pair from a Protected Instance

Function

This API is used to detach a specified replication pair from a specified protected instance.

Constraints and Limitations

  • status of the protection group must be available, protected, failed-over, error-starting, error-stopping, error-reversing, or error-failing-over.

  • status of the protected instance must be available, protected, failed-over, error-starting, error-stopping, error-reversing, error-failing-over, error-deleting, error-reprotecting, error-resizing, invalid, or fault.

  • status of the replication pair must be available, protected, failed-over, error-attaching, error-detaching, error-starting, error-stopping, error-reversing, error-failing-over, error-deleting, error-reprotecting, error-extending, invalid, or fault.

  • The replication pair has been attached to a protected instance.

Note

  • A system disk (attached to /dev/sda or /dev/vda) can be detached only when the server is in the Stopped state. Therefore, stop the server before detaching the system disk.

  • Data disks can be detached online or offline, which means that the server containing the disks can either be in the Running or Stopped state.

    For details about how to detach a disk online, see Storage > Detaching an EVS Disk from a Running ECS in the Elastic Cloud Server User Guide.

    None

  • Example request

    DELETE http://{Endpoint}/v1/{project_id}/protected-instances/00000000632302f501632305f63c000e/detachreplication/6568f7c4-0510-4f39-929d-8ffccbd4fd47

Response

  • Parameter description

    Parameter

    Type

    Description

    job_id

    String

    Specifies the job ID.

    This is a returned parameter when the asynchronous API command is issued successfully. For details about the task execution result, see the description in Querying the Job Status.

  • Example response

    {
       "job_id": "0000000062db92d70162db921dgf00bb"
     }
    

    Or

    {
         "error": {

             "code": "XXX"
         }
     }
    

    In this example, error represents a general error, including badrequest (shown below) and itemNotFound.

    {
         "badrequest": {
             "message": "XXXX",
             "code": "XXX"
         }
