Unmounts cloud disks

Last updated: 2021-05-10 15:24:00

1. API Description

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

This API is used to unmount one or more cloud disks.

  • Batch operation is supported. You can unmount multiple cloud disks from the same CVM in a single request. If any of these cloud disks cannot be unmounted, the operation fails and a specific error code returns.
  • This is an async API. A successful request does not mean that the cloud disks have been unmounted successfully. You can call the DescribeDisks API to query the status of cloud disks. When the status changes from ATTACHED to UNATTACHED, the unmounting is successful.

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
