This operation deregisters backup node from PowerVC. This API takes the backup node ID in the URI as input and takes uninstall and force as optional parameters. The API does not take any request body.

Response codes

Normal Response Code: No Content (204)

Example for deregister backup node API

/v3/{project-id}/backup-nodes/{id}?<uninstall=true&force=false>
