OT: SCSI woes?
As some of you know, I've recently converted to a full scsi system. I compiled
a 2.4.0-test8 kernel with the following options:
SCSI support
SCSI disk support
SCSI CD-ROM support
SCSI generic support
SCSI low-level-drivers --->Adaptec AIC7xxx support
SCSI low-level-drivers --->Enable Tagged Command Queuing
Thats it. When I boot up things appear normal at first:
(scsi0) <Adaptec AIC-7892 Ultra 160/m SCSI host adapter> found at PCI 0/9/0
(scsi0) Wide Channel, SCSI ID=7, 32/255 SCBs
(scsi0) Downloading sequencer code... 392 instructions downloaded
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.2.1/5.2.0

scsi : 1 host.

sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.11
SCSI device sda: hdwr sector= 512 bytes. Sectors= 35843671 [17501 MB] [17.5 GB]
Partition check:
sda: sda1 sda2 sda3
If I'm reading this right, it found my host adapter, found the HD, and the
CD-ROM. The partition check shows sda1 sda2 sda3. All which appears right
to me. Then the follow appears further down the dmesg sequence:
SCSI device sdb: hdwr sector= 512 bytes. Sectors= 35843671 [17501 MB] [17.5 GB]
sdb: sdb1 sdb2 sdb3
Excuse me? sdb? I only have one HD in the system which is broken into three
partitions. Windoze, swap, linux. What does the second entry mean?
OK, finally onto the woes part. When I run cdparanoia -B (burn the entire cd
into individual files) I get the following interesting error:
Checking /dev/cdrom for cdrom...
Testing /dev/cdrom for cooked ioctl() interface
/dev/sr0 is not a cooked ioctl CDROM.
Testing /dev/cdrom for SCSI interface
No generic SCSI device found to match CDROM device /dev/sr0
Well, isn't that interesting? My user account belongs to the cdrom group so I
should have access to the following:
stimpy:~$ ls -l /dev/sr0
brw-rw---- 2 root cdrom 11, 0 Jul 5 12:44 /dev/sr0
stimpy:~$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Sep 22 07:11 /dev/cdrom -> sr0
So /dev/cdrom is pointing to the right place and I have access to sr0, dmesg
is showing that it recognizes the cdrom, I've included generic scsi support
in the kernel, why on earth isn't cdparanoia able to use it? I hope I'm
missing something terrible simple because I'd hate to have spent all that money
to convert to a scsi system and not be able to use it. :(
