That daemon in the .tar.gz should do what you want, but you'll have to 
have 1 daemon per disk in it's current state - I can see no code in it 
to check for multiple instances of it being run, so you'll need to run 
the daemon with the scsi device's device node /dev/sdx for each of the 
/dev/sdx's that you have in the system.

Either that, or you have the source, modify it to probe for all SCSI 
disks in the system and do them all automatically :)
