Raw is used to bind the Linux raw character device to the block device. Any block device can be used: the device driver does not even have to be accessible at binding time (it may later be loaded as a kernel module on demand).

Raw is used in two modes: it either sets raw device bindings or queries existing bindings. "when setting up raw devices, / dev/raw/raw is the device name of the existing raw device node in the file system." A block device bound to can be specified as the path name of an existing block device file by its primary and secondary device number or path name / dev/.
