# cat /sys/class/fc_host/host*/port_name
# 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"
SAS adapter list WWN, address
# cat /sys/class/sas_device/end_device*/sas_address # cat /sys/class/sas_phy/phy-*/sas_address | sort -u
| 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:
# lsscsi --hosts --transport 3 [3] qla2xxx fc:0x50060b00741cc28e,0x0b1900
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:
# lsscsi -H -t --list 3 [3] qla2xxx fc:0x50060b00741cc28e,0x0b1900 transport=fc node_name=0x50060b00741cc28f port_name=0x50060b00741cc28e port_id=0x0b1900 port_type=NPort (fabric via point-to-point) speed=2 Gbit supported_classes=Class 3 tgtid_bind_type=wwpn (World Wide Port Name)
