URI

POST /v2.1/{project_id}/cloudvolumes

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	The user token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.
X-Client-Token	No	String	The idempotence identifier of a request. This parameter value is generated by the client and must be unique among requests. The value is a 36-digit character string in the UUID format and is valid for 8 hours. If multiple requests carry the same idempotent identifier, the requests are considered as an idempotent request and the same response body is returned.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
bssParam	No	BssParamForCreateVolume object	The extended parameter of pay-per-use and yearly/monthly billing.
volume	Yes	CreateVolumeOption object	The information of the disk to be created.
server_id	No	String	The server to attach the disk. The billing mode of the created disk is the same as that of the server. Only ECSs are supported currently. BMSs are not supported.
OS-SCH-HNT:scheduler_hints	No	CreateVolumeSchedulerHints object	The disk scheduling parameter, which can be used to create the disk in a dedicated storage pool.

**Table 4** BssParamForCreateVolume
Parameter	Mandatory	Type	Description
chargingMode	No	String	The billing mode. The default value is postPaid. Values: prePaid: yearly/monthly postPaid: pay-per-use Default: postPaid Enumeration values: postPaid prePaid
isAutoPay	No	String	Whether to pay immediately. This parameter is valid only when chargingMode is set to prePaid. The default value is false. Values: true: An order is immediately paid from the account balance. false: An order is not paid immediately after being created. Default: false Enumeration values: true false
isAutoRenew	No	String	Whether to automatically renew the subscription. This parameter is valid only when chargingMode is set to prePaid. The default value is false. Values: true: automatically renews the subscription. The renewal term is the same as the subscription term. false: does not automatically renew the subscription. Default: false Enumeration values: true false
periodNum	No	Integer	The subscription term. This parameter is valid and mandatory only when chargingMode is set to prePaid. Values: If periodType is set to month, the parameter value ranges from 1 to 9. If periodType is set to year, the parameter value is 1.
periodType	No	String	The unit of the subscription term. This parameter is valid and mandatory only when chargingMode is set to prePaid. Values: month year Enumeration values: month year
cloudServiceConsoleURL	No	String	The URL used to switch to the cloud service console to view information after the subscription is complete.

**Table 5** CreateVolumeOption
Parameter	Mandatory	Type	Description
availability_zone	Yes	String	The AZ where you want to create the disk.
backup_id	No	String	The backup ID. This parameter is mandatory when you create the disk from a backup.
count	No	Integer	The number of disks to be created in a batch. If this parameter is not specified, only one disk will be created. You can create a maximum of 100 disks in a batch. If the disk is created from a backup, batch creation is not possible, and this parameter must be set to 1. If the specified value is a decimal number, the number part will be used by default.
description	No	String	The disk description. You can enter up to 85 characters.
enterprise_project_id	No	String	The enterprise project ID. This ID is associated with the disk during the disk creation.
imageRef	No	String	The image ID. If this parameter is specified, the disk is created from an image.
metadata	No	Map<String,String>	The disk metadata information. The value can be as follows: __system__cmkid: The encryption CMK ID in metadata. This parameter is used together with __system__encrypted for encryption. The length of cmkid is fixed at 36 bytes. NOTE: For details about how to obtain the key ID, see Querying the Key List. __system__encrypted: The encryption field in metadata. The value can be 0 (does not encrypt) or 1 (encrypts). If this parameter is not specified, the encryption attribute of the disk is the same as that of the data source. If the disk is not created from a data source, the disk is not encrypted by default. [full_clone] If the disk is created from a snapshot and linked cloning needs to be used, set this parameter to 0. [hw:passthrough] If this parameter value is true, the disk device type is SCSI, which allows ECS OSs to directly access the underlying storage media and supports SCSI reservation commands. If this parameter value is false, the disk device type is VBD, which supports only simple SCSI read/write commands. If this parameter is not specified, the disk device type is VBD.
multiattach	No	Boolean	Whether the disk is shareable. The value can be true (shareable) or false (non-shareable).
name	No	String	The disk name. If you create one disk, the name value is the disk name. You can enter up to 64 characters. If you create multiple disks (the count value greater than 1), the system automatically adds a hyphen followed by a four-digit incremental number, such as -0000, to the end of each disk name. For example, the disk names can be volume-0001 and volume-0002.
size	Yes	Integer	The disk size, in GiB. The restrictions are as follows: System disk: 1 GiB to 1,024 GiB Data disk: 10 GiB to 32,768 GiB This parameter is mandatory when you create an empty disk or use an image or a snapshot to create a disk. If you use an image or a snapshot to create a disk, the disk size cannot be smaller than the image or snapshot size. This parameter is optional if you create the disk from a backup. If not specified, the disk size is the same as the backup size.
snapshot_id	No	String	The snapshot ID. If this parameter is specified, the disk is created from a snapshot.
volume_type	Yes	String	The disk type. The value can be SATA, SAS, GPSSD, SSD, ESSD, GPSSD2, or ESSD2. SATA: the common I/O type (sold out) SAS: the high I/O type GPSSD: the general purpose SSD type SSD: the ultra-high I/O type ESSD: the extreme SSD type GPSSD2: the general purpose SSD V2 type ESSD2: the extreme SSD V2 type If the specified disk type is not available in the AZ, the disk will fail to be created. NOTE: When you create a disk from a snapshot, ensure that the disk type of the new disk is consistent with that of the snapshot's source disk. For details about disk types, see Disk Types and Performance. Enumeration values: SATA SAS GPSSD SSD ESSD GPSSD2 ESSD2
tags	No	Map<String,String>	The disk tag information.
sys_tags	No	Map<String,String>	The disk system tag information.
iops	No	Integer	The configured IOPS. This parameter is mandatory only when a general purpose SSD V2 or an extreme SSD V2 disk is created. NOTE: To learn the IOPS ranges of the general purpose SSD V2 and extreme SSD V2 disks, see [ [the table of EVS performance data in Disk Types and Performance. Only pay-per-use billing is supported.
throughput	No	Integer	The configured throughput, in the unit of MiB/s. This parameter is mandatory only when a general purpose SSD V2 disk is created. NOTE: To learn the throughput range of the general purpose SSD V2 disks, see [ [the table of EVS performance data in Disk Types and Performance. Only pay-per-use billing is supported.

**Table 6** CreateVolumeSchedulerHints
Parameter	Mandatory	Type	Description
dedicated_storage_id	No	String	The dedicated storage pool ID. If this parameter is specified, the disks will be created in the specified storage pool.

Response Parameters

Status code: 202

**Table 7** Response body parameters
Parameter	Type	Description
job_id	String	The task ID. This parameter is returned when the disk is billed on a pay-per-use basis. For details about how to query the task status, see Querying Task Status..
order_id	String	The order ID. This parameter is returned when the disk is billed on a yearly/monthly basis. If you add a disk to a yearly/monthly server, the system automatically attaches the disk to the server. In this case, this parameter is also returned. If you need to pay for the order, see Paying Yearly/Monthly Product Orders.
volume_ids	Array of strings	The IDs of the disks to be created. If 404 is returned when you query the details of a disk by disk ID, the disk is being created or has failed to be created. You can query whether the disk creation task is complete by task ID. For details, see Querying Task Status.

Status code: 400
