Querying Details About All Disks

Function

This API is used to query details about all disks.

URI

• URI format

  GET /v2/{project_id}/volumes/detail

• Parameter description

  Parameter	Mandatory	Description
  project_id	Yes	The project ID. For details about how to obtain the project ID, see Obtaining a Project ID.

• Request filter parameters

  Parameter	Type	Mandatory	Description
  marker	String	No	The ID of the resource from which the pagination query starts. It is the ID of the last resource on the previous page.
  name	String	No	The disk name. The value can contain a maximum of 255 bytes.
  limit	Integer	No	The maximum number of query results that can be returned. The value ranges from 1 to 1000, and the default value is 1000. The returned value cannot exceed this limit. If the tenant has more than 50 disks in total, you are advised to use this parameter and set its value to 50 to improve the query efficiency. Examples are provided as follows: GET /v2/xxx/volumes/detail?limit=50: Queries the 1–50 disks. GET /v2/xxx/volumes/detail?offset=50&limit=50: Queries the 51–100 disks.
  sort_key	String	No	The keyword based on which the returned results are sorted. The value can be id, status, size, or created_at, and the default value is created_at.
  sort_dir	String	No	The result sorting order. The default value is desc. desc: the descending order asc: the ascending order
  offset	Integer	No	The query offset. All disks after this offset will be queried. The value must be an integer greater than 0 but less than the number of disks.
  status	String	No	The disk status. For details, see EVS Disk Status.
  metadata	String	No	The disk metadata.
  availability_zone	String	No	The AZ information.

Request

The following example shows how to query details of the disks in the available state.

• Example request

  GET https://{endpoint}/v2/{project_id}/volumes/detail?status=available

Response

  multiattach	Boolean	Whether the disk is shareable. true: indicates a shared disk. false: indicates a non-shared disk.
  volume_image_metadata	Object	The metadata of the disk image. This field has a value if the disk is created from an image. Or, it will be left empty. NOTE: For details about volume_image_metadata, see Querying Image Details (Native OpenStack API).

• Parameters in the links field

  Parameter	Type	Description
  href	String	Specifies the corresponding shortcut link.
  rel	String	Specifies the shortcut link marker name.

• Parameters in the attachments field

  Parameter	Type	Description
  server_id	String	Specifies the ID of the server to which the disk is attached.
  attachment_id	String	Specifies the ID of the attachment information.
  attached_at	String	Specifies the time when the disk was attached. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
  host_name	String	Specifies the name of the physical host accommodating the server to which the disk is attached.
  volume_id	String	Specifies the disk ID.
  device	String	Specifies the device name.
  id	String	Specifies the ID of the attached resource.

• Parameters in the metadata field

  Parameter	Type	Description
  __system__encrypted	String	Specifies the parameter that describes the encryption function in metadata. The value can be 0 or 1. 0: indicates the disk is not encrypted. 1: indicates the disk is encrypted. If this parameter does not appear, the disk is not encrypted by default.

  hw:passthrough	String	Specifies the parameter that describes the disk device type in metadata. The value can be true or false. If this parameter is set to 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 (the default type), that is, Virtual Block Device (VBD), which supports only simple SCSI read/write commands. If this parameter does not appear, the disk device type is VBD.
  full_clone	String	Specifies the clone method. When the disk is created from a snapshot, the parameter value is 0, indicating the linked cloning method.
  orderID	String	Specifies the parameter that describes the disk billing mode in metadata.
