You can install bashdb (the Bash Debugger), and run the script: bashdb /sbin/zfcpconf.sh
Bashdb is way better than bash -x or set +x. You can run the script step by step, print the variables, change them onfly, restart the script, and so on. I use Ubuntu, and it's on apt-get repository, so I guess it will be on RedHat repository as well.
