# changeLoadBalancedServerInstances 

## 개요

로드밸런서에 바인드 된 서버 인스턴스 변경

## 설명

로드밸런서에 바인드 된 서버 인스턴스를 변경합니다. 기존 바인드 된 정보를 무시하고 새로 바인드 하는 기능입니다. 바인드/UN 바인드 할 서버 인스턴스가 많을 경우 사용합니다.

## 요청 파라미터

| 파라미터 명 | 필수 여부 | 타입 | 제약사항 | 설명 |
| --- | --- | --- | --- | --- |
| loadBalancerInstanceNo | Yes | String |  | 변경할 로드밸런서 인스턴스 번호 |
| serverInstanceNoList | Yes | List | 중복불가 | 로드밸런서에 바인드 할 서버 인스턴스 번호 리스트 |

## 응답 데이터 타입

- LoadBalancerInstanceList 타입

| LoadBalancerInstanceList extends CommonResponse |
| --- |
| private Integer totalRows; |
| private List<loadbalancerinstance data-tomark-pass=""> loadBalancerInstanceList = new ArrayList<loadbalancerinstance data-tomark-pass="">();</loadbalancerinstance></loadbalancerinstance> |
