I've written one.  Try it!

Easy way:

rpm -ivh http://people.redhat.com/coldwell/coldwell-release-0-1.noarch.rpm
yum install -y scsitool
scsitool --wwid --hbtl --devname

Alternately, you can download source/binaries:

http://people.redhat.com/coldwell/repo/RHEL/5/src/scsitool-0-4.src.rpm
http://people.redhat.com/coldwell/repo/RHEL/5/x86_64/scsitool-0-4.x86_64.rpm

etc.
