Using a GDT-6550 as a 5 Channel SCSI-Adapter
#include hallo.h I just got $subject (5 Channel-FAST-SCSI Raid-Controller) I wanted to use it as a SCSI-Adapter with 5 Channels, to save some PCI-Slots. I have 4 Teac-CD-R58S (8x CD-R) and connected each one to a different channel. -- cat /proc/scsi/scsi -- Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: IBM Model: DDYS-T18350N Rev: S93E Type: Direct-AccessANSI SCSI revision: 03 Host: scsi1 Channel: 00 Id: 04 Lun: 00 Vendor: PIONEER Model: DVD-ROM DVD-303 Rev: 1.10 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 00 Id: 02 Lun: 00 Vendor: PIONEER Model: DVD-ROM DVD-304 Rev: 1.03 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 00 Id: 03 Lun: 00 Vendor: PIONEER Model: DVD-ROM DVD-304 Rev: 1.03 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 01 Id: 00 Lun: 00 Vendor: TEAC Model: CD-R58S Rev: 1.0H Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 02 Id: 01 Lun: 00 Vendor: TEAC Model: CD-R58S Rev: 1.0N Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 03 Id: 06 Lun: 00 Vendor: TEAC Model: CD-R58S Rev: 1.0P Type: CD-ROM ANSI SCSI revision: 02 Host: scsi3 Channel: 04 Id: 04 Lun: 00 Vendor: TEAC Model: CD-R58S Rev: 1.0K Type: CD-ROM ANSI SCSI revision: 02 -- end -- -- cdrecord -scanbus -- Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling Linux sg driver version: 3.1.17 cdrecord: Warning Linux Bus mapping botch. cdrecord: Warning Linux Bus mapping botch. cdrecord: Warning Linux Bus mapping botch. cdrecord: Warning Linux Bus mapping botch.
