Linux系统下查看FC HBA卡的信息
本章节将以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

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
UNIX系统下查看FC HBA卡的信息
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

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
