Linux get the list of FC HBA’s and WWPN

This simple script gives you the list of FC HBA detected in system. It query the sysfs filesystem to get the available fibre channel HBA. Script works for most of the Linux flavors, as specially any of Redhat, SUSE, Fedora and Centos distributions.

This script will not alter any of system configuration rather it just query the sysfs filesystem. Copy the script to server and execute it. Output collected under file “/tmp/hba_list.txt”.

Note

This script will not list the HBA if there is any hardware or driver issue. In such case refer “dmesg“ to troubleshoot further.

 

#!/bin/bash
#
# Display available FC Ports and their WWPN
echo "--------------------------------------------------"
echo -e "\tCollecting the available HBA details. \n\tOutput stored as /tmp/hba_list.txt"
echo "--------------------------------------------------"

for hba in `ls -d /sys/class/fc_host/host*`;do
FC_HOST=`basename $hba`
PortID=`cat $hba/port_id`
wwpn=`cat $hba/port_name`
state=`cat $hba/port_state`
speed=`cat $hba/speed`
hba=`cat $hba/symbolic_name`
cat << EOB >> /tmp/hba_list.txt

FC-Host: $FC_HOST

HBA WWPN : $wwpn PortId: $PortID
HBA State: $state Speed : $speed
EOB
