Cloud DB for MongoDB 인스턴스의 Secondary 서버 대수를 변경합니다. ## 구문 `changeCloudMongoDbSecondaryCount` 구문은 다음과 같습니다. ``` ./ncloud vmongodb changeCloudMongoDbSecondaryCount \ --cloudMongoDbInstanceNo \ --memberServerCount \ --arbiterServerCount \ [--arbiterProductCode ] \ [--regionCode ] \ [--output ] ``` ## 옵션 `changeCloudMongoDbSecondaryCount` 실행 시 지정할 수 있는 옵션을 설명합니다. ### 필수 옵션 `changeCloudMongoDbSecondaryCount`의 필수 옵션입니다. | 옵션 | 타입 | 필수 여부 | 설명 | | --- | --- | --- | --- | | `--cloudMongoDbInstanceNo` | String | Required | Cloud DB for MongoDB 인스턴스 번호 - [getCloudMongoDbInstanceList](/docs/cli-vmongodb-getcloudmongodbinstancelist) 참조 | | `--memberServerCount` | String | Required | 변경할 Cloud DB for MongoDB Member 서버 대수 - `2`~`7` - `memberServerCount`와 `arbiterServerCount`의 합은 `3`~`7`이어야 함 | | `--arbiterServerCount` | String | Required | 변경할 Cloud DB for MongoDB Arbiter 서버 대수 - `0`~`1` - `memberServerCount`와 `arbiterServerCount`의 합은 `3`~`7`이어야 함 | ### 선택 옵션 `changeCloudMongoDbSecondaryCount`의 선택 옵션입니다. 지정하지 않은 옵션에는 기본값이 적용됩니다. | 옵션 | 타입 | 필수 여부 | 설명 | | --- | --- | --- | --- | | `--arbiterProductCode` | String | Optional | Cloud DB for MongoDB Arbiter 서버 상품 코드 - 기본값: 최소 사양 (메모리, CPU 순) - [getCloudMongoDbProductList](/docs/cli-vmongodb-getcloudmongodbproductlist) 호출 시 `infraResourceDetailTypeCode`를 `ARBIT`로 설정하여 확인 | ### 공통 옵션 `vmongodb` 명령에서 공통으로 사용하는 옵션에 대한 정보는 [Cloud DB for MongoDB (VPC) 옵션](/docs/cli-vmongodb#%EC%98%B5%EC%85%98)을 참조해 주십시오. ## 예시 Secondary 서버 대수 변경 요청이 성공하면 Cloud DB for MongoDB 인스턴스의 구성 정보와 각 서버 인스턴스의 상세 정보가 반환됩니다. ### 명령 명령 예시는 다음과 같습니다. ``` ./ncloud vmongodb changeCloudMongoDbSecondaryCount \ --cloudMongoDbInstanceNo 34567890 \ --memberServerCount 3 \ --arbiterServerCount 0 \ --regionCode KR \ --output json ``` ### 출력 출력 예시는 다음과 같습니다. ``` { "changeCloudMongoDbSecondaryCountResponse": { "totalRows": 1, "cloudMongoDbInstanceList": [ { "cloudMongoDbInstanceNo": "34567890", "cloudMongoDbServiceName": "mongodb-01", "cloudMongoDbInstanceStatusName": "settingUp", "cloudMongoDbInstanceStatus": { "code": "CREAT", "codeName": "CLOUD DATABASE(VPC) Created 상태" }, "cloudMongoDbInstanceOperation": { "code": "SETUP", "codeName": "CLOUD DATABASE(VPC) Setup OP" }, "generationCode": "G2", "clusterType": { "code": "SHARDED_CLUSTER", "codeName": "Sharding Cluster Type -
