How to identify/get QLogic WWN on SuSE Enterprise Linux

1.       First identify your installed or recognized

lspci | grep -i fibre



2.       On SuSE Enterprise Linux 10/11, it is on /sys/class/fc_host/hostX/port_name where X is your device.

ls /sys/class/fc_host



3.       To get the WWN, run:

more /sys/class/fc_host/host3/port_name





4.       Sample with multiple QLogic HBAs:

cat /sys/class/fc_host/host[3-4]/port_name

    Even though this is not the best way, I was still proud of myself for coming up with this one liner (execute from /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

    Sample output:

    [root@centos63node01 scsi_host]# for i in 0 1 2 3 4 5; do cat host$i/device/fc_host/host$i/port_name; done
    cat: host0/device/fc_host/host0/port_name: No such file or directory
    cat: host1/device/fc_host/host1/port_name: No such file or directory
    cat: host2/device/fc_host/host2/port_name: No such file or directory
    cat: host3/device/fc_host/host3/port_name: No such file or directory
