    1. API Description

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

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

    • Batch operation is supported. You can mount multiple cloud disks to one CVM in a single request. If any of these cloud disks cannot be mounted, the operation fails and a specific error code returns.
    • This is an async API. A successful request indicates that the mounting is initiated. You can call the DescribeDisks API to query the status of cloud disks. If the status changes from ATTACHING to ATTACHED, the mounting is successful.

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

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
