# changeLoadBalancedServerInstances

## 概要

ロードバランサにバインドされたサーバインスタンス変更

## 説明

ロードバランサにバインドされたサーバインスタンスを変更します。 既存バインドされた情報を無視して、新しくバインドする機能です。バインド/UNバインドするサーバインスタンスが多い場合、使います。

## リクエストパラメータ

| パラメータ名 | 必須 | タイプ | 制約事項 | 説明 |
| --- | --- | --- | --- | --- |
| loadBalancerInstanceNo | Yes | String |  | 変更するロードバランサインスタンス番号 |
| serverInstanceNoList | Yes | List | 重複不可 | ロードバランサにバインドするサーバインスタンス番号リスト |

## レスポンスデータタイプ

- LoadBalancerInstanceListタイプ

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

| LoadBalancerInstance |

| private String loadBalancerInstanceNo; |
| private String virtualIp; |
| private String loadBalancerName; |
| private CommonCode loadBalancerAlgorithmType; |
| private String loadBalancerDescription; |
| private Date createDate; |
| private String domainName; |
| private String loadBalancerInstanceStatusName; |
| private CommonCode loadBalancerInstanceStatus; |
