-.Sh NAME
-.Nm blkdev
-.Nd generic block device driver
-.Sh DESCRIPTION
-The
-.Nm
-driver supports generic block-oriented devices, such as non-volatile
-memory storage devices.
-It provides a hardware independent layer for such storage devices, allowing them
-to concentrate on the hardware-specific details, while
-.Nm
-takes care of all the other details, such as
-.Xr dkio 7I .
-.Lp
-The
-.Nm
-driver only supports block-oriented, random-access devices.
-It does not support traditional rotational media and does not support
-SCSI commands.
-.Lp
-The most typical use case for
-.Nm
-devices is to be used to host a file system, such as
-.Xr pcfs 7FS
-or
-.Xr zfs 7FS .

-.It Va cn
-A controller number, typically one for each instance of
-each underlying hardware dependent device driver (there can be multiple
-such drivers in the system.) Controller numbers are dynamically assigned
-by the system.
-.It Va dn
-Generally, each instance of the underlying hardware will have a
-logical unit number as well.
-.It Va sn
-This is the
-.Em slice
-number, representing a subset of the disk.
