Linux Enterprise Server and CentOS/Redhat

/sys/class/scsi_host/hostN/device/fc_host/hostN/port_name

Where “N” is the number of device for your fiber HBAs.

Here’s my shortcut bash command if you don’t want to look around. This command is executed in the /sys/class/scsi_host directory.
#cd /sys/class/scsi_host
#for i in 0,1,2,3,4,5;do cat host$i/device/fc_host/host$i/port_name;done

Or

To view details about transporting HBA card
#systool -c fc_transport -v

WWPN – World Wide Port Name
WWNN – World Wide Node Name
OUI – Organizationally Unique Identifier

To view HBA card details and WWN details

systool -c fc_host –v

# systool -c fc_host -v | grep “port_name”
port_name = “0x5001438001347fdc”
port_name = “0x5001438001347fde”
port_name = “0x50014380013471f0″
port_name = “0x50014380013471f2″

#Useful command to find to list the FC Adapter
Get wwn for qlogic
lspci | grep -i Fibre
====================
To find WWN on linux with Emulex:
If you find difficult to find WWN on linux with Emulex HBA use below hbacmd to list the HBAs. This only available if hbanyware installed.

cd /usr/sbin/hbanyware
[root@tilak_phy01 hbanyware]# ./hbacmd ListHBAs

Manageable HBA List
Port WWN : 11:00:00:00:d9:58:bf:92
Node WWN : 10:00:00:00:b9:58:ba:92
Fabric Name: 20:3f:01:04:51:a1:71:00
Flags : 1100a980
Host Name : tilak_phy01
Mfg : Emulex Corporation
===================
On Redhat 4 and below (including OEL and CentOS), the /proc/scsi/{adapter-type}/{n} file contains the HBA WWN information as shown below.

{adapter-type} can be either qlaxxxx for QLogic adapters (or) lpfc for Emulex adapters.
Please substitude n with either 0, 1, or 2 according to your system.

The example belows shows the WWN number of the qlogic 2300 adapter on RedHat 3.

Ex:-

cat /proc/scsi/qla2300/1
QLogic PCI to Fibre Channel Host Adapter for QLA2460:
Firmware version: 4.00.23, Driver version 7.07.05
Entry address = f888d060

OR

cat /proc/scsi/qla2xxx/1
<snip>
SCSI Device Information:
scsi-qla0-adapter-node=200000xxxxxxxxxx;
scsi-qla0-adapter-port=210000xxxxxxxxx;
<snip>

Check state

cat /sys/class/fc_host/host[0-9]/port_state

ls -l /sys/block/sd[c-h]/device displays

Using the command scsi_id for each /block/a-h (for example, for /dev/sda we type scsi_id -g -s /block/sda) generates the output:
SATA WD2502ABYS-23B7 WD-WCAT1H504691
SATA HUA721075KLA330 GTA260P8H8893E
3600a0b8000753b49000006244dca89ae
3600a0b8000754bad000006144dca8a1f
3600a0b8000753b49000006274dca89ef
3600a0b8000754bad000006164dca8ad3
3600a0b8000753b490000062a4dca8aa5
3600a0b8000754bad000006194dca8b10
The two initial Scsi ids represent the local disks (/dev/sda and /dev/sdb). The remaining six represent the Scsi ids of the fibre channel attached LUNs

To determine the mapping between SCSI HBTL addresses & disks

Code:
sg_map -x
/dev/sg0 1 0 0 0 5 /dev/scd0
/dev/sg1 2 0 0 0 0 /dev/sda
/dev/sg2 2 0 1 0 0 /dev/sdb
/dev/sg3 2 0 2 0 0 /dev/sdc
/dev/sg4 2 0 3 0 0 /dev/sdd
/dev/sg5 3 0 1 0 0 /dev/sde

To Scan Luns:-

/usr/bin/rescan-scsi-bus.sh

Using prtconf

root@ sunserver:/root# prtconf -vp | grep -i wwn

Using luxadm

Run the following command to obtain the physical path to the HBA Ports

root@ sunserver:/root$ luxadm -e port
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl CONNECTED
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0,1/fp@0,0:devctl NOT CONNECTED

With the physical path obtained from the above command, we can trace the WWN numbers as follows. here I use the physical path to the one that is connected:

root@ sunserver:/root$ luxadm -e dump_map /devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl

For Solaris 8 and 9:

Run the following script to determine the WWNs of the HBAs that are currently being utilized:

#!/bin/sh for i in `cfgadm |grep fc-fabric|awk ‘{print $1}’`;

do

dev=”`cfgadm -lv $i|grep devices |awk ‘{print $NF}’`” wwn= \

“`luxadm -e dump_map $dev |grep ‘Host Bus’|awk ‘{print $4}’`”

echo “$i: $wwn” done

bash-2.03# luxadm -e port
