Kudos to verdepollo for giving you what you asked for. Here's what I think you need:
Code:
MODEL=$(hdparm -I /dev/sdc | <some code here>$)
scsiadd -p |  
awk '/^Host: scsi/ { scsiid=substr($2,5,1) " " $4 " " $6 " " $8 }
       /Model: '"$MODEL"/' { print scsiid; found=1; exit(0); }
       END { exit(1-found); }'

Zaxxon and I posted about the same time. We take the same general approach but vary in our actual tactics. The exit() condition in mine allows you to test the return code of the command to see if it worked, ie, to put in a script, pipeline or if statement and fail appropriately.
