NAME
       scsi - device driver supporting access to a SCSI device

SYNOPSIS
       /dev/scsi/scsi (adapname@devicecode (adapaddr[,adapid]),
               deviceid[, d])

DESCRIPTION
       The scsi device driver accesses any Small Computer System Interfaces
       device.  It allows user space applications to issue commands to a
       device that has been configured in the system with this driver.

       The scsi device driver accesses devices via special file nodes in
       /dev, as described below:

       scsi      indicates that this device was configured with the scsi
                 device driver.
       adapname is the name of the SCSI adapter; currently supported
                 adapters include cisc, insc, ncsc, and dgsc
       @devicecode
                 is the adapter's hexadecimal device code, preceded by the @
                 character
       adapaddr is the adapter's hexadecimal address
       adapid   is the adapter's SCSI ID (range 0-7, recommended 7 or 6).
                 Omit to accept the default id 7.
       deviceid is the disk drive's SCSI ID (range 0-7)
       d         is the disk drive's logical unit number (range 0-7).  Omit
                 to accept the default unit number 0.

       The scsi interface supports open, ioctl, and close system calls to
       the device.

EXAMPLE
       The following statement accesses a generic SCSI disk:

       /dev/scsi/scsi(ncsc@7(FFFB0000,7),3,0)

       The device uses the SCSI adapter ncsc; the adapter's device code is
       7; the adapter's address is FFFB0000; the adapter's SCSI ID is 7; the
       device's SCSI ID is 3, and the logical unit number is 0.

FILES
       /dev/scsi/*
       /usr/include/sys/intdguserscsiioctl.h
