Ⅰ 紅旗Linux SP3如何用命令查看光纖卡的信息，謝謝！
系統的/proc/scsi/qla2xxx目錄下一般存在兩個文件：1、2或者3、4，這些文件包含FC HBA卡的配置信息。
[root@localhost qla2xxx]# cat 3
QLogic PCI to FibreChannel Host Adapter for QLA2342:
Firmware version 3.03.18IPX, Driver version 8.01.02-d4
ISP:ISP2312, Serial# P21735
RequestQueue = 0x11f580000,Response Queue = 0x11f4d0000
Request Queue count =4096, Response Queue count = 512
Total number of activecommands = 0
Total number ofinterrupts = 3354
Device queue depth = 0x10
Number of freerequest entries = 4094
Number of mailboxtimeouts = 0
Number of ISP aborts= 0
Number of loopresyncs = 0
Number of retries forempty slots = 0
Number of reqs inpending_q= 0, retry_q= 0, done_q= 0, scsi_retry_q= 0
Host adapter:loopstate = <READY>, flags = 0x1a03
Dpc flags = 0x4000000

SCSI DeviceInformation:
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 theOS.
其中，SCSI Device Information下面的scsi-qla0-adapter-port=2100001882374738便是主機光纖卡的WWN號。
RedHat AS5系統的/sys/class/fc_host/host*/port_name 這個文件包含了所有已被系統發現的FC HBA卡的信息，使用查看命令查看該文件的內容即可看到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
