### NAME

uk - SCSI user-level driver

### SYNOPSIS

uk* at scsibus? target ? lun ?

### 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.

### KERNEL CONFIGURATION

If a count is given, that number of uk devices will be configured into the NetBSD kernel.

### 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]`
  unknown SCSI devices.

### DIAGNOSTICS

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

### SEE ALSO

ioctl(2), cd(4), ch(4), scsi(4), sd(4), ss(4), st(4)

### HISTORY

The uk driver appeared in 386BSD 0.1.
