Creating a Disk (Discarded)

Function

This API is used to create a disk.

This API has been discarded. Use the EVS API "Creating EVS Disks (OpenStack Cinder API v2)".

URI

POST /v2/{project_id}/os-volumes

POST /v2.1/{project_id}/os-volumes

Table 1 describes the parameters in the URI.

Table 1 Parameter description

Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID.

Request

Table 2 describes the request parameters.

Table 2 Request parameters

Parameter	Mandatory	Type	Description
availability_zone	No	String	Specifies the AZ to which the volume to be created belongs. If the specified AZ does not exist, creating the volume failed, and the volume is in error state. The AZ to which the volume to be created belongs must be specified in the public cloud system.
display_description	No	String	Specifies the volume description.
snapshot_id	No	String	Specifies the snapshot ID. If this parameter is specified, the volume is to be created from a snapshot.
size	Yes (If the volume is created from a snapshot, this parameter is optional.)	Integer	Specifies the volume size. Unit: GB
display_name	No	String	Specifies the volume name.
volume_type	No	String	Specifies the volume type. Currently, the value can be SSD, SAS, SATA, co-p1, or uh-l1. SSD: specifies the ultra-I/O disk type. SAS: specifies the high I/O disk type. SATA: specifies the common I/O disk type. co-p1: specifies the high I/O (performance-optimized I) disk type. uh-l1: specifies the ultra-high I/O (latency-optimized) disk type. NOTE: EVS disks of the co-p1 and uh-l1 types are used exclusively for high performance computing (HPC) and SAP HANA ECSs.
metadata	No	Object	Specifies the volume metadata.

Response

Table 3 describes the response parameters.

Table 3 Response parameters

Parameter	Type	Description
id	String	Specifies the disk ID in UUID format.
displayName	String	Specifies the volume name.
status	String	Specifies the volume status.
attachments	Array of objects	Specifies the volume attachment information.
availabilityZone	String	Specifies the AZ to which the volume belongs.
createdAt	String	Specifies the time when the volume was created.
displayDescription	String	Specifies the volume description.
volumeType	String	Specifies the volume type.
snapshotId	String	Specifies the snapshot ID.
metadata	Object	Specifies the volume metadata.
size	Integer	Specifies the size of the volume.
