Request Parameters

None

Response Parameters

Status code: 200

**Table 2** Response body parameters
Parameter	Type	Description
volume	CinderVolumeDetail object	Definition The returned disk. Range N/A

**Table 3** CinderVolumeDetail
Parameter	Type	Description
id	String	Definition The disk ID. Range N/A
links	Array of Link objects	Definition The disk URI. Range N/A
name	String	Definition The disk name. Range N/A
status	String	Definition The disk status. For details, see EVS Disk Status. Range N/A
attachments	Array of VolumeAttachment objects	Definition Whether the disk is attached. Range N/A
availability_zone	String	Definition The AZ to which the disk belongs. Range N/A
source_volid	String	Definition The source disk ID. This parameter has a value if the disk is created from a source disk. This field is currently not supported. Range N/A
snapshot_id	String	Definition The snapshot ID. This parameter has a value if the disk is created from a snapshot. Range N/A
description	String	Definition The disk description. Range N/A
bootable	String	Definition Whether the disk is bootable. Range true: The disk is bootable. false: The disk is not bootable.
created_at	String	Definition The time when the disk was created. Range Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
volume_type	String	Definition The disk type. Range The value can be SATA, SAS, GPSSD, SSD, ESSD, GPSSD2, or ESSD2. SATA: the common I/O type (end-of-sale) 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
metadata	VolumeMetadata object	Definition The disk metadata. If metadata does not contain the hw:passthrough field, the disk device type is VBD. If metadata does not contain the __system__encrypted field, the disk is unencrypted. Range N/A
size	Integer	Definition The disk capacity, in GiB. Range N/A
shareable	Boolean	Definition Whether the disk is shareable. Note: This field has been deprecated. Use multiattach. Range N/A
multiattach	Boolean	Definition Whether the disk is shareable. Range true: shared disk false: non-shared disk
os-vol-tenant-attr:tenant_id	String	Definition The ID of the project to which the disk belongs. Range N/A
volume_image_metadata	Object	Definition The metadata of the disk image. For details about the volume_image_metadata field, see Querying Image Details (Native OpenStack API V2, Deprecated). Range N/A
os-vol-host-attr:host	String	Definition The reserved field. Range N/A
os-volume-replication:extended_status	String	Definition The reserved field. Range N/A
consistencygroup_id	String	Definition The reserved field. Range N/A
iops	iops object	Definition The disk IOPS information. This parameter is returned only for a general purpose SSD V2 or an extreme SSD V2 disk. Range N/A
throughput	throughput object	Definition The disk throughput information. This parameter is returned only for a general purpose SSD V2 disk. Range N/A
updated_at	String	Definition The time when the disk was updated. Range N/A
replication_status	String	Definition The reserved field. Range N/A
user_id	String	Definition The reserved field. Range N/A
encrypted	Boolean	Definition The reserved field. Range N/A
snapshot_policy_id	String	Definition The ID of the snapshot policy applied to the disk. Range N/A

href	String	Definition The corresponding shortcut link. Range N/A
rel	String	Definition The shortcut link marker name. Range N/A

**Table 5** VolumeAttachment
Parameter	Type	Description
attached_at	String	Definition The time when the disk was attached. Range Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
attachment_id	String	Definition The attachment ID. Range N/A
device	String	Definition The device name. Range N/A
host_name	String	Definition The name of the physical host housing the cloud server to which the disk is attached. Range N/A
id	String	Definition The ID of the attached resource. Range N/A
server_id	String	Definition The ID of the server to which the disk is attached. Range N/A
volume_id	String	Definition The disk ID. Range N/A

**Table 6** VolumeMetadata
Parameter	Type	Description
__system__cmkid	String	Definition 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. Range Use an HTTPS request to obtain the key ID. For details, see Querying the Key List.
__system__encrypted	String	Definition The encryption field in metadata. If this parameter does not appear, the disk is unencrypted. Range 0: no encryption 1: encryption
hw:passthrough	String	Definition The parameter that describes the disk device type in metadata. If this parameter does not appear, the disk device type is VBD. Range If this parameter value is true, the disk device type is SCSI, which allows ECS OSs to directly access the underlying storage media. SCSI reservation commands are supported. If this parameter value is false, the disk device type is VBD (default device type), which supports only simple SCSI read/write commands.
