I got:
a. modprobe scst
b. modprobe scst_disk
In order to run with *scst_disk* you need to patch and
rebuild the kernel. Please follow SCST readme to do this task
If you don't want to patch and rebuild the kernel, you can
run with *scst_vdisk* and get the same performance. I attach
here an example to setup *scst_vdisk*

FATAL: Error inserting scst_disk
(/lib/modules/2.6.16.21-0.8-smp/extra/dev_handlers/scst_disk.ko): No such device
c. cat /proc/scsi_tgt/scsi_tgt

Doesn't the Device handler need to be dev_disk?
