Scenario
You can mount an EVS disk to elastic bare metal. Different EVS processing means are available when you unsubscribe from/delete the elastic bare metal. If Release with Instance is enabled for the EVS, the EVS will be released automatically when the elastic bare metal is released. If Release with Instance is not enabled, unbind the mounted data disk from the elastic bare metal first and retain the data disk.
l The EVS (system disk or data disk mounted when you create the elastic bare metal) purchased in the same order as the elastic bare metal is released with the instance by default and the setting cannot be modified.
l The EVS (data disk mounted after the elastic bare metal is created) purchased in a different order from the elastic bare metal will not be released with the instance by default. Release with Instance can be enabled for the EVS as needed.
