scsiDirectLib

NAME

scsiDirectLib - SCSI library for direct access devices (SCSI-2)

ROUTINES

scsiStartStopUnit( ) - issue a START_STOP_UNIT command to a SCSI device
scsiReserve( ) - issue a RESERVE command to a SCSI device
scsiRelease( ) - issue a RELEASE command to a SCSI device

DESCRIPTION

This library contains commands common to all direct-access SCSI devices. These routines are separated from scsi2Lib in order to create an additional layer for better support of all SCSI direct-access devices.

Commands in this library include:

Command	Op Code
FORMAT UNIT	(0x04)
READ (6)	(0x08)
READ (10)	(0x28)
READ CAPACITY	(0x25)
RELEASE	(0x17)
RESERVE	(0x16)
MODE SELECT (6)	(0x15)
MODE SELECT (10)	(0x55)
MODE SENSE (6)	(0x1a)
MODE SENSE (10)	(0x5a)
START STOP UNIT	(0x1b)
WRITE (6)	(0x0a)
WRITE (10)	(0x2a)

INCLUDE FILES

scsiLib.h, scsi2Lib.h
