  device	String	The device name.
  id	String	The ID of the attached disk.

• Parameters in the metadata field

  Parameter	Type	Description
  __system__encrypted	String	The encryption field in metadata. 0: indicates a non-encrypted disk. 1: indicates an encrypted disk. If this parameter does not appear, the disk is not encrypted.
  __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.
  hw:passthrough	String	The parameter that describes the disk device type in metadata. The value can be true or false. true indicates the SCSI device type, which allows ECS OSs to directly access the underlying storage media. SCSI reservation commands are supported. false indicates the VBD device type (the default type), which supports only simple SCSI read/write commands. If this parameter does not appear, the disk device type is VBD.
  full_clone	String	The clone method. If the disk is created from a snapshot, value 0 indicates the linked cloning method.
