for FCSX in `ssh $lpar_wwpn_number_list lscfg | grep fcs | awk '{ print $2 }'`
echo $lpar_wwpn_number_list${CSV}${FCSX}${CSV}`ssh $lpar_wwpn_number_list lscfg -vl ${FCSX} | grep "Network Address" | sed -e "s/^.*\.//" | sed 's/../&:/g;s/:$//'`${CSV}`ssh $lpar_wwpn_number_list lscfg -l ${FCSX} | awk '{ print $2 }'`
