# Creating a DR Drill

#### Function

This API is used to create a disaster recovery (DR) drill.

#### Constraints and Limitations

- status of the protection group must be available, protected, failed-over, error-starting, error-stopping, error-reversing, error-reprotecting, or error-failing-over.
- Do not perform a DR drill before the first time data synchronization completes. Otherwise, the drill server may not start properly.
- If drill_vpc_id is specified (the system uses an existing drill VPC), the drill VPC CIDR block must be consistent with that of the VPC for the protection group. If drill_vpc_id is not specified, the system automatically creates a drill VPC.
- When you use a created drill VPC to create a drill, the subnet ACL rule of the drill VPC will be different from that of the VPC of the protection group. You need to manually set them to be the same one if needed.
- When you create a DR drill, if the VPC of the protection group has a customized routing table and subnets configured, the corresponding routing table will not be automatically created for the drill VPC. You need to manually create it if needed.

  Table 1 disaster_recovery_drill field description
  Parameter | Mandatory | Type | Description
  --- | --- | --- | ---
  server_group_id | Yes | String | Specifies the ID of a protection group. For details, see Querying Protection Groups.
  drill_vpc_id | No | String | Specifies the drill VPC ID. If you do not specify this parameter, the system will automatically create a drill VPC.

- Example request
  POST https://{Endpoint}/v1/{project_id}/disaster-recovery-drills

      {
               "disaster_recovery_drill": {
                        "name": "dr_drill_test",
                        "server_group_id":"c2aee29a-2959-4d01-9755-01cc76a4d17d",
                        "drill_vpc_id":"87d505be-e984-455e-ad84-588c73fb258b"
          }
      }

#### 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": "0000000011db92d36662db9d20df32ch"
        }

  Or

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

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

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