AttachVscToFilesystems - Cloud Parallel File Storage - Alibaba Cloud Documentation Center

Associates the VSC device with the file system.

Operation description

Only CPFS for Lingjun supports this operation.
Batch execution is supported. In batch execution, only one VscId can be associated with multiple FileSystemIDs, meaning the VscId in the ResourceIds must be the same.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
