Raw devices are indicated by an
``r''
preceding the device name.
The driver can be opened with either rewind on close
(/dev/rst*
)
or no rewind on close
(/dev/nrst*
)
options.
The tape format is specified by adding 8 or 16 to the device number.
For example, for the wt0 device's raw rewind on close device nodes,
/dev/rwt0
is the 150 MByte density device,
/dev/rwt8
is the 120 MByte density device, and
/dev/rwt16
is the 60 MByte device.
