因为linux版本太多,我们就以主流的,为例,RedHat Linux AS4、RedHat Linux AS5、SuSe Linux 9和SuSe Linux 10为例介绍在Linux系统中如何查看FC HBA卡的信息。
在查看FC HBA卡前请确保FC HBA卡物理连接正常，指示灯正常。
1、RedHat Linux AS4 和 SuSE Linux 9
RedHat Linux AS4与SuSE Linux 9中查看FC HBA卡信息的方法基本一样，在此以RedHat AS4为例介绍如何查看FC HBA卡的信息。
在RedHat AS4或SuSE Linux 9系统的/proc/scsi/qla2xxx目录下一般存在两个文件：1、2或者3、4，这些文件包含FC HBA卡的配置信息。
[root@localhost qla2xxx]# pwd
/proc/scsi/qla2xxx
[root@localhost qla2xxx]# ls
3 4
[root@localhost qla2xxx]# cat 3

SCSI Device Information:
scsi-qla0-adapter-node=2000001882374738;
scsi-qla0-adapter-port=2100001882374738;
FC Port Information:
scsi-qla0-port-0=200000188237b206:210000188237b206:010a00:81;
SCSI LUN Information:
(Id:Lun) * - indicates lun is not registered with the OS.
其中，SCSI Device Information下面的scsi-qla0-adapter-port=2100001882374738便是主机光纤卡的WWN号。
2、RedHat Linux AS5和SuSE Linux 10
RedHat Linux AS5与SuSE Linux 10中查看FC HBA卡信息的方法基本一致，在此在RedHat Linux AS5为便介绍如何查看FC HBA卡信息。
RedHat AS5系统的 /sys/class/fc_host/host*/port_name 这个文件包含了所有已被系统发现的FC HBA卡的信息，使用查看命令查看该文件的内容即可看到FC HBA卡的信息。
查看WWPN：cat /sys/class/fc_host/host*/port_name
查看WWNN：cat /sys/class/fc_host/host*/node_name
四UNIX系统下查看FC HBA卡的信息
最后就是Unix了,在此介绍实际应用较为广泛的UNIX系统中如何查看FC HBA卡信息，包括IBM AIX、SUN SOLARIS、HP-UNIX。
1、IBM AIX
① 查看AIX主机连接的光纤设备
# lsdev -Cc adapter -S a | grep fcs
fcs0 Available 09-08 FC Adapter
fcs1 Available 09-09 FC Adapter
上面的输出显示有2块光纤卡：fcs0和fcs1。
② 查看光纤卡fcs0的WWN号
# lscfg -vpl fcs0
fcs0 U787B.001.DNWG664-P1-C1-T1 FC Adapter

Hardware Location Code......U787B.001.DNWG664-P1-C1-T1
上面命令的输出中，加粗红色的部分就是光纤卡的WWN号。
2、 SUN SOLARIS
① 查询现有存储设备和光纤设备，可以读到包括磁盘设备的WWN号
# luxadm probe
② 查看HBA的prot，可以得到HBA卡的port值以及属性
# luxadm -e port
/devices/pci@0,0/pci1022,7450@2/pci1077,101@1/fp@0,0:devctl NOT CONNECTED
/devices/pci@0,0/pci1022,7450@2/pci1077,101@1,1/fp@0,0:devctl CONNECTED
从中可以看到仅有一块光纤卡连接到存储设备。
③ 选择已经连接的HBA卡，查看其WWN号
# luxadm -e dump_map /devices/pci@0,0/pci1022,7450@2/pci1077,101@1/fp@0,0:devctl
Pos Port_ID Hard_Addr Port WWN Node WWN Type
0 0 0 210000e08b19827a 200000e08b19827a 0x1f (Unknown Type,Host Bus Adapter)
3、HP-UNIX
① 列出HP机上连接的光纤卡设备
# ioscan -fnC fc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/3/1/0 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)
/dev/fcd0
fc 1 0/3/1/1 fcd CLAIMED INTERFACE HP A6826-60001 2Gb Dual Port PCI/PCI-X Fibre Channel Adapter (FC Port 2)
/dev/fcd1
从上面命令的输出可以看 ,/dev/fcd0 和 /dev/fcd1两块光纤卡。
② 查看光纤卡的WWN号
# fcmsutil /dev/fcd0
Vendor ID is = 0x001077

PCI Mode = PCI-X 133 MHz
ISP Code version = 3.3.18
ISP Chip version = 3
Topology = PTTOPT_FABRIC
Link Speed = 2Gb
Local N_Port_id is = 0xa10500
Previous N_Port_id is = None
N_Port Node World Wide Name = 0x50060b00001db241
N_Port Port World Wide Name = 0x50060b00001db240
Switch Port World Wide Name = 0x205e000dec0e2e00
Switch Node World Wide Name = 0x2001000dec0e2e01
Driver state = ONLINE
Hardware Path is = 0/3/1/0
Maximum Frame Size = 2048
Driver-Firmware Dump Available = NO
Driver-Firmware Dump Timestamp = N/A
Driver Version = @(#) libfcd.a HP Fibre Channel ISP 23xx & 24xx Driver B.11.23.04 /ux/core/isu/FCD/kern/src/common/wsio/fcd_init.c:Oct 18 2005,08:21:11
其中红色加粗部分显示了HBA卡的WWNN和WWPN号，另外还能看到该HBA卡连接的光纤交换机端口的WWN号。
