1. API Description

Domain name for API request:

This API (ResizeDisk) is used to expand the capacity of the cloud disk.

  • Only elastic cloud disks can be expanded. The cloud disk type can be queried in the Portable field in the output parameters through the API DescribeDisks. For the cloud disk created along with the CVM, the capacity can only be expanded via the API ResizeInstanceDisks.
  • This API is an asynchronous API. The cloud disk is not immediately expanded to the specified size as the API successfully returns results. You can use the API DescribeDisks to query the cloud disk status. The cloud disk in the status of "EXPANDING" is in the process of capacity expansion. When the status changes to "UNATTACHED", the capacity expansion is completed.

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:
