I don't have any experience with Linux and SCSI drives and was wondering if someone could give me some basic-level/newbie pointers on SCSI setup.
The computer has an AdvanSys card in it and I've recompiled the kernel with advansys, generic SCSI, and SCSI CD-ROM support. This seems okay as dmesg reports: scsi0 : AdvanSys SCSI 3.1E: PCI Ultra-Wide: BIOS C8000/7FFF, IO E800/3F, IRQ 10 scsi : 1 host. Vendor: YAMAHA Model: CRW4416S Rev: 1.0f Type: CD-ROM ANSI SCSI revision: 02 Detected scsi CD-ROM sr0 at scsi0, channel 0, id 2, lun 0 Vendor: IBM Model: DDRS-39130D Rev: DC1B Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 6, lun 0 scsi : detected 1 SCSI cdrom 1 SCSI disk total. sr0: scsi3-mmc drive: 16x/16x writer cd/rw xa/form2 cdda tray Uniform CDROM driver Revision: 2.54 SCSI device sda: hdwr sector= 512 bytes. Sectors= 17850000 [8715 MB] [8.7 GB] Similarly, a cat of /proc/scsi/scsi reports: Attached devices: Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: YAMAHA Model: CRW4416S Rev: 1.0f Type: CD-ROM ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 06 Lun: 00 Vendor: IBM Model: DDRS-39130D Rev: DC1B Type: Direct-Access ANSI SCSI revision: 02 An output of "cat /proc/devices" reveals: Block devices: 2 fd 3 ide0 8 sd 11 sr 22 ide1 That all looks okay (I guess) but I cannot access the devices. I did a /dev/MAKEDEV update and I have these devices in /dev: brw-rw---- 1 root disk 8, 0 May 18 22:59 sda brw-rw---- 1 root disk 11, 0 May 18 22:59 scd0 If I try to do an "fdisk /dev/sda" I get a message of "Unable to read /dev/sda" along with: May 19 06:13:21 spartacus kernel: SCSI disk error : host 0 channel 0 id 6 lun 0 return code = 25040000 May 19 06:13:21 spartacus kernel: scsidisk I/O error: dev 08:00, sector 0 Similarly, a command of "mount /dev/scd0 /mnt" gives this info in /var/log/messages: May 19 06:13:21 spartacus kernel: SCSI disk error : host 0 channel 0 id 6 lun 0 return code = 25040000 May 19 06:13:21 spartacus kernel: scsidisk I/O error: dev 08:00, sector 0 May 19 06:15:35 spartacus kernel: sr00:00: old sense key None May 19 06:15:49 spartacus kernel: Non-extended sense class 0 code 0x0 <3>sr0: CDROM (ioctl) error, command: Start/Stop Unit 00 00 00 03 00 May 19 06:15:49 spartacus kernel: sr00:00: old sense key None May 19 06:15:49 spartacus kernel: Non-extended sense class 0 code 0x0 <6>cdrom: open failed.

I'm guessing I don't have the devices set up properly, but perusing docs and howtos didn't turn up anything.
