Querying Details About an EVS Disk

Function

This API is used to query details about an EVS disk.

Calling Method

For details, see Calling APIs.

URI

GET /v2/{project_id}/volumes/{volume_id}

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	The project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
volume_id	Yes	String	The disk ID.

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.

Response Parameters

Status code: 200

**Table 3** Response body parameters
Parameter	Type	Description
volume	CinderVolumeDetail object	The returned disk.

**Table 4** CinderVolumeDetail
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 VolumeAttachment objects	Whether the disk is attached.
availability_zone	String	The AZ to which the disk belongs.
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.
bootable	String	Whether the disk is bootable. true: The disk is bootable. false: The disk is not bootable.
created_at	String	The time when the disk was created. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
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
metadata	VolumeMetadata object	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 not encrypted.
size	Integer	The disk size, in GiB.
shareable	Boolean	Whether the disk is shareable. Note: This field has been deprecated. Use multiattach.
multiattach	Boolean	Whether the disk is shareable.
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	Object	The metadata of the disk image. For details about the volume_image_metadata field, see Querying Image Details (Native OpenStack API).
os-vol-host-attr:host	String	The reserved field.
os-volume-replication:extended_status	String	The reserved field.
consistencygroup_id	String	The reserved field.
iops	iops object	The disk IOPS information. This parameter is returned only for a general purpose SSD V2 or an extreme SSD V2 disk.
throughput	throughput object	The disk throughput information. This parameter is returned only for a general purpose SSD V2 disk.
updated_at	String	The time when the disk was updated.
replication_status	String	The reserved field.
user_id	String	The reserved field.
encrypted	Boolean	The reserved field.

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

**Table 6** VolumeAttachment
Parameter	Type	Description
attached_at	String	The time when the disk was attached. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
attachment_id	String	The attachment ID.
device	String	The device name.
host_name	String	The name of the physical host housing the cloud server to which the disk is attached.
id	String	The ID of the attached disk.
server_id	String	The ID of the server to which the disk is attached.
volume_id	String	The disk ID.

**Table 7** VolumeMetadata
Parameter	Type	Description
__system__cmkid	String	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: Use an HTTPS request to obtain the key ID. For details, see Querying the Key List.
__system__encrypted	String	The encryption field in metadata. The value can be 0 (no encryption) or 1 (encryption). If this parameter does not appear, the disk is not encrypted.
full_clone	String	If the disk is created from a snapshot and linked cloning needs to be used, set this parameter to 0.
hw:passthrough	String	If this parameter is set to 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 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 available, the disk device type is VBD.

**Table 8** iops
Parameter	Type	Description
frozened	Boolean	The frozen tag. Default: false
id	String	The ID of the disk IOPS.
total_val	Integer	The IOPS.
volume_id	String	The disk ID.

**Table 9** throughput
Parameter	Type	Description
frozened	Boolean	The frozen tag. Default: false
id	String	The throughput ID.
total_val	Integer	The throughput.
volume_id	String	The disk ID.

Status code: 400

**Table 10** Response body parameters
Parameter	Type	Description
error	Error object	The error message returned if an error occurs.

**Table 11** Error
Parameter	Type	Description
code	String	The error code returned if an error occurs. For details about error codes and their meanings, see Error Codes.
message	String	The error message returned if an error occurs.
