[getCloudMongoDbInstanceList](/docs/ja/cli-vmongodb-getcloudmongodbinstancelist)を参照 | | `--shardCount` | String | Required | 変更後の Cloud DB for MongoDBインスタンスのシャード数 - `3`~`5` - シャードは追加のみ可能で削除はできない | ### 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 Shard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 changeCloudMongoDbShardCount \ --cloudMongoDbInstanceNo 34567890 \ --shardCount 3 \ --regionCode KR \ --output json ``` ### 出力 出力の例は次の通りです。 ``` { "changeCloudMongoDbShardCountResponse": { "totalRows": 1, "cloudMongoDbInstanceList": [ { "cloudMongoDbInstanceNo": "34567890", "cloudMongoDbServiceName": "mongodb-01", "cloudMongoDbInstanceStatusName": "running", "cloudMongoDbInstanceStatus": { "code": "CREAT", "codeName": "CLOUD DATABASE(VPC) Created状態" }, "cloudMongoDbInstanceOperation": { "code": "NULL", "codeName": "CLOUD DATABASE(VPC) Null OP" }, "generationCode": "G2", "clusterType": { "code": "SHARDED_CLUSTER", "codeName": "Sharding Cluster Type -
