**Table 3** Response body parameters
Parameter	Type	Description
volume	VolumeDetail object	The disk details.

**Table 4** VolumeDetail
Parameter	Type	Description
id	String	The disk ID.
links	Array of Link objects	The disk URI.
name	String	The disk name.
status	String	The disk status. For details, see EVS Disk Status.
attachments	Array of Attachment objects	The disk attachment information.
availability_zone	String	The AZ to which the disk belongs.
os-vol-host-attr:host	String	The reserved field.
source_volid	String	The source disk ID. This parameter has a value if the disk is created from a source disk. This field is currently not supported.
snapshot_id	String	The snapshot ID. This parameter has a value if the disk is created from a snapshot.
description	String	The disk description.
created_at	String	The time when the disk was created. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
os-vol-tenant-attr:tenant_id	String	The ID of the tenant to which the disk belongs. The tenant ID is the same as the project ID.
volume_image_metadata	Map<String,Object>	The metadata of the disk image. NOTE: For details about the volume_image_metadata field, see Querying Image Details (Native OpenStack API).
volume_type	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
size	Integer	The disk size, in GiB.
consistencygroup_id	String	The reserved field.
bootable	String	Whether the disk is bootable. true: The disk is bootable. false: The disk is not bootable.
metadata	Map<String,Object>	The disk metadata. __system__cmkid: The encryption CMK ID in metadata. This parameter is used together with __system__encrypted for encryption. The length of the CMK ID is fixed at 36 bytes. 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 (no encryption) or 1 (encryption). 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 The creation method when the disk is created from a snapshot. 0: linked clone 1: full clone 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 is set to false, the disk device type is VBD, which is also the default type. VBD supports only simple SCSI read/write commands. If this parameter is not specified, the disk device type is VBD. orderID The parameter that describes the disk billing mode in metadata. If this parameter has a value, the disk is billed on a yearly/monthly basis. If this parameter is not specified, the disk is billed on a pay-per-use basis.
updated_at	String	The time when the disk was updated. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
encrypted	Boolean	This field is currently not supported.
replication_status	String	The reserved field.
os-volume-replication:extended_status	String	The reserved field.
os-vol-mig-status-attr:migstat	String	The reserved field.
os-vol-mig-status-attr:name_id	String	The reserved field.
shareable	String	Whether the disk is shareable. The value can be true (shareable) or false (non-shareable). This field has been deprecated. Use multiattach.
user_id	String	The reserved field.
service_type	String	The service type. Supported services are EVS, DSS, and DESS.
multiattach	Boolean	Whether the disk is shareable.
dedicated_storage_id	String	The ID of the dedicated storage pool housing the disk.
dedicated_storage_name	String	The name of the dedicated storage pool housing the disk.
tags	Map<String,String>	The disk tags. This field has values if the disk has tags. Or, it is left empty.
wwn	String	The unique identifier used when attaching the disk.
enterprise_project_id	String	The ID of the enterprise project that the disk has been added to. For details about how to obtain enterprise project IDs and enterprise project features, see Overview.
serial_number	String	The disk serial number. This field is returned only for non-HyperMetro SCSI disks and is used for disk mapping in the VM.
iops	iops object	The disk IOPS information. This parameter appears only for a general purpose SSD V2 or an extreme SSD V2 disk.
throughput	throughput object	The disk throughput information. This parameter appears only for a general purpose SSD V2 disk.
root_resource_type	String	The root resource type.
root_resource_id	String	The root resource ID.
parent_resource_type	String	The parent resource type.
parent_resource_id	String	The parent resource ID.

**Table 5** Link
Parameter	Type	Description
href	String	The corresponding shortcut link.
rel	String	The shortcut link marker name.
