While the multiple LUNs thingy is annoying, it can be dealt with without
recompiling the kernel if you want. If your kernel has multiple LUNs
compiled in, the first ide-scsi device will consume the first eight
device files, both the /dev/sg* files used for cd burner operation, and
the /dev/sr* and /dev/scd* files (they are the same thing) used for
mounting of CDROMs. If you only have eight of those device files, then
there are none for a second ide-scsi device to use. The really easy fix
is to just create an additional device file for the second ide-scsi
device.
For example, if you only have /dev/sga - sgh, then create an additional
device file like this:
# cd /dev
# mknod sgi c 21 8
Similarly for /dev/scd8:
# cd /dev
# mknod scd8 b 11 8
Check the permissions to make sure they match the other similar device
files. Reboot and things should be working.
