Releases a Pay-As-You-Go data disk. You can release a basic disk, an ultra disk, or an SSD.


When you call this operation, note that:

  • This operation does not delete manual snapshots of your disk.
  • You can call ModifyDiskAttribute to configure whether automatic snapshots are retained or released together with the disk. We recommend that you delete unnecessary snapshots to ensure enough snapshot data storage for periodical automatic snapshot policies.
  • When you release a disk, the disk must be in the Available state.
  • If no disk with the specified ID exists, the request will be ignored.


You can use API Explorer to perform debugging. API Explorer allows you to perform various operations to simplify API usage. For example, you can retrieve APIs, call APIs, and dynamically generate SDK example code.
