创建云硬盘

功能介绍

创建按需或包周期云硬盘。

在创建包周期云硬盘的场景下：

如果您需要查看订单可用的优惠券，请参考"查询订单可用优惠券"。
如果您需要支付订单，请参考"支付包周期产品订单"。
如果您需要退订该包周期资源，请参考“退订包周期资源”。

调用方法

请参见如何调用API。

URI

POST /v2.1/{project_id}/cloudvolumes

表1 路径参数
参数	是否必选	参数类型	描述
project_id	是	String	项目ID。获取方法请参见"获取项目ID"。

请求参数

表2 请求Header参数
参数	是否必选	参数类型	描述
X-Auth-Token	是	String	用户Token。通过调用IAM服务获取用户Token接口获取（响应消息头中X-Subject-Token的值）。
X-Client-Token	否	String	请求的幂等标识。该参数的值由客户端生成，需要确保不同请求的参数值唯一，取值为36位的UUID格式字符串，有效期为8小时。携带相同幂等标识的多个请求，会认为多个请求为同一个幂等请求，会返回相同的响应体。

表3 请求Body参数
参数	是否必选	参数类型	描述
bssParam	否	BssParamForCreateVolume object	按需和包周期的扩展参数
volume	是	CreateVolumeOption object	待创建的云硬盘信息
server_id	否	String	创建云硬盘并挂载到目标虚拟机。创建的云硬盘的计费模式会与虚拟机的计费模式保持一致。目前只支持ECS服务的虚拟机，暂不支持BMS的裸金属服务器。
OS-SCH-HNT:scheduler_hints	否	CreateVolumeSchedulerHints object	云硬盘调度参数，可用于指定云硬盘创建到某个专属存储池中

表4 BssParamForCreateVolume
参数	是否必选	参数类型	描述
chargingMode	否	String	功能说明：计费模式。默认值为postPaid。取值范围： prePaid：包年包月 postPaid：按需
isAutoPay	否	String	功能说明：是否立即支付。chargingMode为PrePaid时该参数会生效。默认值为false。取值范围： true：立即支付，从账户余额中自动扣费 false：不立即支付，创建订单暂不支付
isAutoRenew	否	String	功能说明：是否自动续订。chargingMode为prePaid时该参数会生效。默认值为false。取值范围： true：自动续订，自动续订周期与订购周期相同 false：不自动续订
periodNum	否	Integer	功能说明：订购周期数，chargingMode为prePaid时该参数会生效，并且该参数为为必选。取值范围： periodType为month时，为[1-9] periodType为year时，为[1-1]
periodType	否	String	功能说明：订购周期单位。chargingMode为prePaid时该参数会生效，并且该参数为必选。取值范围： month：月 year：年

表5 CreateVolumeOption
参数	是否必选	参数类型	描述
availability_zone	是	String	指定要创建云硬盘的可用区。
backup_id	否	String	备份ID，从备份创建云硬盘时为必选。
count	否	Integer	批量创云硬盘的个数。如果无该参数，表明只创建1个云硬盘，目前最多支持批量创建100个。从备份创建云硬盘时，不支持批量创建，数量只能为“1”。如果发送请求时，将参数值设置为小数，则默认取小数点前的整数。
description	否	String	云硬盘的描述。最大支持85个字符。
enterprise_project_id	否	String	企业项目ID。创建云硬盘时，给云硬盘绑定企业项目ID。
imageRef	否	String	镜像ID，指定该参数表示创建云硬盘方式为从镜像创建云硬盘。
metadata	否	Map<String,String>	创建云硬盘的metadata信息可选参数如下:[__system__cmkid] metadata中的加密cmkid字段，与__system__encrypted配合表示需要加密，cmkid长度固定为36个字节。说明：请求获取密钥ID的方法请参考："查询密钥列表"。 [__system__encrypted] metadata中的表示加密功能的字段,0代表不加密,1代表加密。不指定该字段时,云硬盘的加密属性与数据源保持一致,如果不是从数据源创建的场景,则默认不加密。 [full_clone] 从快照创建云硬盘时，如需使用link克隆方式，请指定该字段的值为0。 [hw:passthrough] true表示云硬盘的设备类型为SCSI类型，即允许ECS操作系统直接访问底层存储介质。支持SCSI锁命令。 false表示云硬盘的设备类型为VBD (虚拟块存储设备 , Virtual Block Device)类型，即为默认类型，VBD只能支持简单的SCSI读写命令。该字段不存在时，云硬盘默认为VBD类型。
multiattach	否	Boolean	是否为共享云硬盘。true为共享盘，false为普通云硬盘。
name	否	String	云硬盘名称。如果为创建单个云硬盘，name为云硬盘名称。最大支持64个字符。创建的云硬盘数量（count字段对应的值）大于1时，为区分不同云硬盘，创建过程中系统会自动在名称后加“-0000”的类似标记。例如：volume-0001、volume-0002。
size	是	Integer	云硬盘大小，单位为GiB，其限制如下： -系统盘：1GiB-1024GiB -数据盘：10GiB-32768GiB -创建空白云硬盘和从镜像/快照创建云硬盘时，size为必选，且云硬盘大小不能小于镜像/快照大小。 -从备份创建云硬盘时，size为可选，不指定size时，云硬盘大小和备份大小一致。
snapshot_id	否	String	快照ID，指定该参数表示创建云硬盘方式为从快照创建云硬盘。
volume_type	是	String	云硬盘类型。目前支持"SATA"，"SAS"，"GPSSD"，"SSD"，"ESSD"，"GPSSD2"，"ESSD2"七种。 "SATA"为普通IO云硬盘(已售罄) "SAS"为高IO云硬盘 "GPSSD"为通用型SSD云硬盘 "SSD"为超高IO云硬盘 "ESSD"为极速IO云硬盘 "GPSSD2"为通用型SSD V2云硬盘 "ESSD2"为极速型SSD V2云硬盘当指定的云硬盘类型在availability_zone内不存在时，则创建云硬盘失败。说明：从快照创建云硬盘时，volume_type字段必须和快照源云硬盘保持一致。了解不同云硬盘类型的详细信息，请参见云硬盘类型及性能介绍。
tags	否	Map<String,String>	云硬盘标签信息。
iops	否	Integer	给云硬盘配置iops，购买GPSSD2、ESSD2类型的云硬盘时必填，其他类型不能设置。说明：了解GPSSD2、ESSD2类型的iops大小范围，请参见云硬盘类型及性能介绍里面的云硬盘性能数据表。只支持按需计费。
throughput	否	Integer	给云硬盘配置吞吐量，单位是MiB/s，购买GPSSD2类型云盘时必填，其他类型不能设置。说明：了解GPSSD2类型的吞吐量大小范围，请参见云硬盘类型及性能介绍里面的云硬盘性能数据表。只支持按需计费。

表6 CreateVolumeSchedulerHints
参数	是否必选	参数类型	描述
dedicated_storage_id	否	String	指定专属存储池ID，表示将云硬盘创建在该ID对应的存储池中。

响应参数

状态码： 202

表7 响应Body参数
参数	参数类型	描述
job_id	String	任务ID，云硬盘为按需计费时返回该参数。如果需要查询job的状态，请参考："查询job的状态"。
order_id	String	订单ID，云硬盘为包周期计费时返回该参数。直接在包周期云服务器上新增云硬盘，系统会自动将云硬盘挂载到包周期云服务器上。该情形下也会返回该参数。如果您需要支付订单，请参考："支付包周期产品订单"。
volume_ids	Array of strings	待创建的云硬盘ID列表。通过云硬盘ID查询云硬盘详情，若返回404 可能云硬盘正在创建中或者已经创建失败。通过JobId查询云硬盘创建任务是否完成查询job的状态。

状态码： 400
