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 386BSD 0.1
