|
.Sh SYNOPSIS
|
|
.Cd "uk* at scsibus? target ? lun ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for a process to address devices on the
|
|
.Tn SCSI
|
|
bus for which there is no configured driver.
|
|
.Pp
|
|
A
|
|
.Tn SCSI
|
|
adapter must also be separately configured into the system before
|
|
this driver makes sense.
|
|
.Pp
|
|
.Sh KERNEL CONFIGURATION
|
|
If a
|
|
.Ar count
|
|
is given, that number of
|
|
.Nm
|
|
devices will be configured into the
|
|
.Nx
|
|
kernel.
|
|
.Pp
|
|
.Sh IOCTLS
|
|
The
|
|
.Nm
|
|
driver has no ioctls of its own but rather acts as a medium for the generic
|
|
.Xr scsi 4
|
|
ioctls.
|
|
These are described in
|
|
.Pa Aq sys/scsiio.h .
