Function

This API is used to query EVS disks.

URI

• URI format

  GET /v2/{project_id}/volumes

• Parameter description

  Parameter	Mandatory	Description
  project_id	Yes	Specifies 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	Specifies the ID of the last record on the previous page. The returned value is the value of the item after this one.
  name	String	No	Specifies the disk name. The value can contain a maximum of 255 bytes.
  limit	Integer	No	Specifies 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?limit=50: Queries the 1–50 disks. GET /v2/xxx/volumes?offset=50&limit=50: Queries the 51–100 disks.
  sort_key	String	No	Specifies 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	Specifies the result sorting order. The default value is desc. desc: indicates the descending order. asc: indicates the ascending order.
  offset	Integer	No	Specifies the 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	Specifies the disk status. For details, see EVS Disk Status.
  metadata	String	No	Specifies the disk metadata.
  availability_zone	String	No	Specifies the AZ.
