  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 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.
  __system__cmkid	String	Specifies 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.
  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.

• Parameters in the error field

  Parameter	Type	Description
  message	String	The error message returned if an error occurs.
  code	String	The error code returned if an error occurs. For details about the error code, see Error Codes.
