# NAME

`uk` — SCSI user-level driver

# SYNOPSIS

`uk* at scsibus?`

# DESCRIPTION

The `uk` driver provides support for a process to address devices on the SCSI bus for which there is no configured driver.

A SCSI adapter must also be separately configured into the system before this driver makes sense.

# IOCTLS

The `uk` driver has no ioctls of its own but rather acts as a medium for the generic scsi(4) ioctls. These are described in `<sys/scsiio.h>`.

# FILES

/dev/uk[0-255]
  uk{x} is the 'xth' unknown device found.

# DIAGNOSTICS

All scsi(4) debug ioctls work on `uk` devices.

# SEE ALSO

cd(4), ch(4), scsi(4), sd(4), st(4)

# HISTORY

The `uk` driver appeared in NetBSD 1.0.
