Once you do the "echo "scsi add-single-device 0 0 4 0" > /proc/scsi/scsi", try
# cat /proc/scsi/scsi
You should get a list of entries for all of your attached, recognized scsi
devices. They will look like this.
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: MATSHITA Model: CD-ROM CR-508 Rev: XS03
Type: CD-ROM ANSI SCSI revision: 02
This is of course for my cdrom drive, at id 3. You info will differ,
what's important is that there exists an entry for your drive.
If it doesn't exits try...
# cat /proc/devices
You should see an entry under Block devices, "11 sr". If you don't, then
the scsi cd support isn't compiled in, and/or the module isn't loaded.
If this exist, then do..
# ls -al /dev/scd*
You should get...
brw-rw---- 1 root disk 11, 0 /dev/scd0
brw-rw---- 1 root disk 11, 1 /dev/scd1
... on up until
brw-rw---- 1 root disk 11, 7 /dev/scd7
for a total of eight scsi cdroms. If these don't exist, make them with
# /dev/MAKEDEV scd*
and if this doesn't work, you can make the nodes directly with mknod
# mknod /dev/scd0 b 11 0
# mknod /dev/scd1 b 11 1
so on and so forth until you have made all of them...
# mknod /dev/scd7 b 11 7
Now try your mount again. If that doesn't work, then I don't really know
what your problem is.
# mount -t iso9660 /dev/scd0 /cdrom
