1. API Description

Domain name for API request: cbs.tencentcloudapi.com.

This API (DetachDisks) is used to unmount cloud disks.

  • Batch operations are supported. Multiple cloud disks mounted to the same CVM can be unmounted in batch. If there is a cloud disk that does not allow this operation, the operation is not performed and a specific error code is returned.
  • This API is an asynchronous API. When the request successfully returns results, the cloud disk is not unmounted from the CVM immediately. You can use the API DescribeDisks to query the cloud disk status. If the status changes from "ATTACHED" to "UNATTACHED", the cloud disk is unmounted.

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: cbs.ap-shanghai-fsi.tencentcloudapi.com
