[getCloudMongoDbInstanceList](/docs/ja/cli-vmongodb-getcloudmongodbinstancelist)を参照 | | `--memberServerCount` | String | Required | 変更後の Cloud DB for MongoDB Memberサーバ台数 - `2`~`7` - `memberServerCount`と`arbiterServerCount`の合計は`3`~`7`でなければならない | | `--arbiterServerCount` | String | Required | 変更後の Cloud DB for MongoDB Arbiterサーバ台数 - `0`~`1` - `memberServerCount`と`arbiterServerCount`の合計は`3`~`7`でなければならない | ### 任意オプション `changeCloudMongoDbSecondaryCount`の任意オプションです。指定しない場合、オプションにはデフォルト値が適用されます。 | オプション | タイプ | 必須の有無 | 説明 | | --- | --- | --- | --- | | `--arbiterProductCode` | String | Optional | Cloud DB for MongoDB Arbiterサーバ商品コード - デフォルト: 最小スペック (メモリ、CPUの順) - [getCloudMongoDbProductList](/docs/ja/cli-vmongodb-getcloudmongodbproductlist)の呼び出し時、`infraResourceDetailTypeCode`を`ARBIT`に設定して確認 | ### 共通オプション `vmongodb`コマンドで共通して使用するオプションについては、[Cloud DB for MongoDB (VPC)のオプション](/docs/ja/cli-vmongodb#%EC%98%B5%EC%85%98)を参照してください ## 例 Secondaryサーバ台数の変更リクエストが成功すると、Cloud DB for MongoDBインスタンスの構成情報と、各サーバインスタンスの詳細情報が返されます。 ### コマンド コマンドの例は次の通りです。 ``` ./ncloud vmongodb changeCloudMongoDbSecondaryCount \ --cloudMongoDbInstanceNo 34567890 \ --memberServerCount 3 \ --arbiterServerCount 0 \ --regionCode KR \ --output json ``` ### 出力 出力の例は次の通りです。 ``` { "changeCloudMongoDbSecondaryCountResponse": { "totalRows": 1, "cloudMongoDbInstanceList": [ { "cloudMongoDbInstanceNo": "34567890", "cloudMongoDbServiceName": "mongodb-01", "cloudMongoDbInstanceStatusName": "settingUp", "cloudMongoDbInstanceStatus": { "code": "CREAT", "codeName": "CLOUD DATABASE(VPC) Created状態" }, "cloudMongoDbInstanceOperation": { "code": "SETUP", "codeName": "CLOUD DATABASE(VPC) Setup OP" }, "generationCode": "G2", "clusterType": { "code": "SHARDED_CLUSTER", "codeName": "Sharding Cluster Type -
