To find the WWPN and Other information of Qlogic HBAs without restarting the host, you can use any of the following methods.
for i in `seq 0 4` ;
do echo #####Host $i ######;
cat /sys/class/fc_host/host$i/port_name;
cat /sys/class/fc_host/host$i/port_state;
cat /sys/class/fc_host/host$i/port_type;
cat /sys/class/fc_host/host$i/speed;
cat /sys/class/fc_host/host$i/supported_speeds;
done
Your output may be the following,
