You will get lots of stuff, including a line like:

Host: scsi0 Channel: 00 Id: 00 Lun: 00

immediately before your CDROM is mentioned.

Taking the first 3 numbers, calling them X, Y and Z (OP puts his numbers
in of course), do this:

echo "scsi add-single-device X Y Z 1" > /proc/scsi/scsi
echo "scsi add-single-device X Y Z 2" > /proc/scsi/scsi
echo "scsi add-single-device X Y Z 3" > /proc/scsi/scsi
etc

That will cause each of the LUNs to be probed.

Sheesh! I've used that for hot-swapping SCSI devices in the past, but
it never occurred to me to try it for multiple-LUN support. I always
assumed I needed the kernel option turned on for multi-LUN support.

I'll be sure to remember that tip for the next time I need multi-LUN
support on a kernel that doesn't have it! (Multi-slot USB memory card
readers are a common example of a device using multiple LUNs.)

Hi

Are you recalling the "probe all LUNs" kernel option? IIRC the kernel always
has support for LUNs>0 but just does not bother scanning for them (to save
time as mentioned) - so it should do what you wish.

Cheers
