Capture in a file the following. chmod +x. Run. It should show you your FC HBAs, if they're online, speed, HBA WWID and the Switch Port each is connected to (if connected):

#!/bin/ksh
#
# Display available FC Ports and their WWIDS
echo "show_hbas.ksh"
echo "v.0.1 Alzhy MegaCruel (CopyLeft 02/2010)"
echo " "
for hba in `ls -d /sys/class/fc_host/host*`;do
FC_HOST=`basename $hba`
PortID=`cat $hba/port_id`
wwid=`cat $hba/port_name`
state=`cat $hba/port_state`
speed=`cat $hba/speed`
hba=`cat $hba/symbolic_name`
cat <FC-Host: $FC_HOST ($hba)
---------------------------------------------------------------------------
HBA WWID : $wwid PortId: $PortID
HBA State: $state Speed : $speed

EOB
done

Cheers!
