<cli prompt='#'>
# cat /sys/class/fc_host/host*/port_name  
</cli>



# yum install sysfsutils

To check the available HBA ports :

# systool -c fc_host
Class = "fc_host"

  Class Device = "host2"
    Device = "host2"

  Class Device = "host3"
    Device = "host3"

To find the WWNs for the HBA ports :

# systool -c fc_host -v | grep port_name
    port_name           = "0x500143802426baf4"
    port_name           = "0x500143802426baf6"

To check the state of the HBA ports (online/offline) :

# systool -c fc_host -v | grep port_state
    port_state          = "Online"
    port_state          = "Online"

^long option format^short option format^description^
|	--brief	|	-b	|	reduces single line output to tuple plus primary device name. With --pdt option inserts the PDT (device type) in hex between tuple and primary device name.	|
|	--classic	|	-c	|	generate output similar to 'cat /proc/scsi/scsi'	|
|	--controllers	|	-C	|	lists NVMe controllers and SCSI hosts. This is a synonym for --hosts	|
|	--device	|	-d	|	show device node's major and minor numbers	|
|	--generic	|	-g	|	show scsi generic device node name	|
|	--help	|	-h	|	print usage message then exit	|
|	--hosts	|	-H	|	rather than list SCSI devices (logical units), list SCSI hosts instead	|
|	--kname	|	-k	|	show kernel name (as found in sysfs) instead of device node name (as found in the /dev directory)	|
|	--list	|	-L	|	show <attribute>=<value> pairs, one per line, indented by two or more spaces	|
|	--long	|	-l	|	show <attribute>=<value> pairs, several to a line. can be used multiple times for more output and different format.	|
|	--long-unit	|	-U	|	show the un-truncated logical unit name. This may cause the "single device per line" form of output to exceed 80 columns with UUID and EUI-128 logical unit names	|
|	--lunhex	|	-x	|	show the LUN part of the tuple as hex following T10 (SAM-5) conventions.	|
|	--no-nvme	|	-N	|	don't list NVMe devices (or controllers if --hosts is given)	|
|	--pdt	|	-D	|	displays Peripheral Device Type (PDT) is hexadecimal, prefixed by "0x"	|
|	--protection	|	-p	|	show protection information (T10-DIF).	|
|	--protmode	|	-P	|	show negotiated protection information mode	|
|	--scsi_id	|	-i	|	show udev derived information in /dev/disk/by-id/ directory	|
|	--size	|	-s	|	show disk size in human readable form.  |
|	--sysfsroot=PATH	|	-y PATH	|	Uses PATH as sysfs mount point (default sysfs mount point is '/sys')	|
|	--sz-lbs	|	-S	|	show disk size as number of logical blocks; when given twice adds a comma followed the logical block size in bytes (typically either 512 or 4096)	|
|	--transport	|	-t	|	show transport information. If '--hosts' not given then this will be for targets. If '--hosts' is given then this will be for initiators (i.e. hosts). More information shown when used with '--list'.	|
|	--unit	|	-u	|	show the LU name in the place of the manufacturer, model and revision. Needs lk >= 3.15	|
|	--verbose	|	-v	|	increase verbosity of output. May be used multiple times to further increase verbosity.	|
|	--version	|	-V	|	print out the version and the date of last code change then exits	|
|	--wwn	|	-w	|	show the WWN for disks in the place of the manufacturer, model and revision	|

When the '--hosts' option is used with '--transport' then transport information for the initiator (port) is output:

<cli prompt='#'>
# lsscsi --hosts --transport 3
[3]    qla2xxx       fc:0x50060b00741cc28e,0x0b1900
</cli>

This shows for host 3 the driver is called qla2xxx, the transport is FC, the initiator's port name is in NAA-5 format with the final (hex) number being the initiator's port identifier. Adding '--list' will again add "name=value" pairs:
<cli prompt='#'>
# lsscsi -H -t --list 3
