    1. API Description

    Domain name for API request:

    This API is used to expand the capacity of a cloud disk.

    • This API supports only the expansion of elastic cloud disks. To query the type of a cloud disk, you can call the DescribeDisks API and check the Portable field in the response. To expand non-elastic cloud disks, you can call the ResizeInstanceDisks API.
    • This is an async API. A successful return of this API does not mean that the cloud disk has been expanded successfully. You can call the DescribeDisks API to query the status of a cloud disk. EXPANDING indicates that the expansion is in process.

    A maximum of 20 requests can be initiated per second for this API.

    Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example:

    We recommend you to use API Explorer
