AttachDisks

Last updated: 2020-10-16 18:49:02

1. API Description

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

This API (AttachDisks) is used to mount cloud disks.

  • Batch operations are supported. Multiple cloud disks can be mounted to a CVM. 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. If the request for mounting the cloud disk successfully returns results, the operation of mounting cloud disk has been initiated at the background. You can use the API DescribeDisks to query the cloud disk status. If the status changes from "ATTACHING" to "ATTACHED", the cloud disk is mounted.

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
