This assumes that metadata is being stored in the backend device to recover the previous target configuration. Since this is not yet implemented, this check collides with some of the core initialization (e.g., sysblock initialization when a page is formed by several sectors). We take this check out and for now rely on that the right target will be created instead. When metadata is stored to recover a target, this check will come natural as part of the recovery strategy.
