How to find the WWID of your HBAs in Linux Redhat

# systool -vc fc_host
Example output below… what you are looking for is the “port name.” In this case, I have 2 HBAs, considered host5 and host6.

Class = “fc_host”

Class Device = “host5”
Class Device path = “/sys/class/fc_host/host5”
fabric_name = “0x20000024ff27cb78”
issue_lip =
node_name = “0x20000024ff27cb78”
port_id = “0x000000”
port_name = “0x21000024ff27cb78”
port_state = “Online”
port_type = “Unknown”
speed = “unknown”
supported_classes = “Class 3”
supported_speeds = “1 Gbit, 2 Gbit, 4 Gbit”
symbolic_name = “QLE2462 FW:v5.03.02 DVR:v8.03.01.05.05.06-k”
system_hostname = “”
tgtid_bind_type = “wwpn (World Wide Port Name)”
uevent =

Device = “host5”
Device path = “/sys/devices/pci0000:00/0000:00:07.0/0000:1f:00.0/host5”
ct =
els =
fw_dump =
nvram = “ISP ”
optrom_ctl =
optrom =
reset =
sfp = “”
uevent =
vpd = “\ufffd2”

Class Device = “host6”
Class Device path = “/sys/class/fc_host/host6”
fabric_name = “0x100000051e35ad55”
issue_lip =
node_name = “0x20000024ff27cb79”
port_id = “0x011000”
port_name = “0x21000024ff27cb79”
port_state = “Online”
port_type = “NPort (fabric via point-to-point)”
speed = “4 Gbit”
supported_classes = “Class 3”
supported_speeds = “1 Gbit, 2 Gbit, 4 Gbit”
symbolic_name = “QLE2462 FW:v5.03.02 DVR:v8.03.01.05.05.06-k”
system_hostname = “”
tgtid_bind_type = “wwpn (World Wide Port Name)”
uevent =

Device = “host6”
Device path = “/sys/devices/pci0000:00/0000:00:07.0/0000:1f:00.1/host6”
ct =
els =
fw_dump =
nvram = “ISP ”
optrom_ctl =
optrom =
reset =
sfp = “”
uevent =
vpd = “\ufffd2”

    I really tend to agree with every little thing that
    is put into writing throughout “How to find the WWID of your HBAs in Linux Redhat Tech Notes
    Diaries”. Thanks a lot for all the details.
    Thank you-Shantell
