Querying Details About All EVS Disks

Function

This API is used to query details about all EVS disks. It does not support enterprise project authorization.

URI

• URI format

  GET /v2/{project_id}/volumes/detail

• Parameter description

  Parameter	Mandatory	Description
  project_id	Yes	The 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

  iops	Object	The disk IOPS information. This parameter is only returned for a general purpose SSD V2 disk.
  throughput	Object	The disk throughput information. This parameter is only returned for a general purpose SSD V2 disk.

• Parameters in the links field

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

• Parameters in the attachments field

  Parameter	Type	Description
  server_id	String	The ID of the server to which the disk is attached.
  attachment_id	String	The ID of the attachment information.
  attached_at	String	The time when the disk was attached. Time format: UTC YYYY-MM-DDTHH:MM:SS.XXXXXX
