Detaching an EVS Disk from an ECS

This API is used to detach an EVS disk from an ECS.

This API is an asynchronous API. After the detachment request is successfully delivered, a job ID is returned. This does not mean the detachment is complete. You need to call the API by referring to Querying Job Execution Status to query the job status. The SUCCESS status indicates that the detachment is successful.
