本文介绍如何在Aix下查看HBA卡的WWN号信息，什么是HBA卡？这个前边讲过了，这里说说什么是WWN号，WWN即World Wide Name的简写，是用来标识网络上的一个连接或连接集合,主要用于FC和SAS设备上。就像网卡的MAC地址一样,WWN是用在光纤网络的，所以，简言之，WWN就似乎HBA卡的MAC地址。
在AIX下，查看HBA名和数量,有两个命令prtconf和lsdev命令都可以查看得到：
# prtconf|grep fc
+ fcs2 U7879.001.DQD629X-P1-C5-T1 FC Adapter
* fcnet2 U7879.001.DQD629X-P1-C5-T1 Fibre Channel Network Protocol
Device
+ fcs1 U7879.001.DQDZZCR-P1-C5-T1 FC Adapter
* fcnet1 U7879.001.DQDZZCR-P1-C5-T1 Fibre Channel Network Protocol
Device
+ fcs0 U7879.001.DQD630D-P1-C2-T1 FC Adapter
* fcnet0 U7879.001.DQD630D-P1-C2-T1 Fibre Channel Network Protocol
Device
可以看到，这是3块HBA卡，
# lsdev -Cc adapter|grep fcs
fcs0 Available 0F-08 FC Adapter
fcs1 Available 0G-08 FC Adapter
fcs2 Available 0H-08 FC Adapter
AIX下查看HBA卡WWN号，这里也可以用两个命令：lscfg和fcstat,fcstat命令看到的信息更为详细，能查看到当前运行的状态：
# lscfg -vpl fcs0

看到了吧，其实在AIX系统下查看wwn的命令和方法很简单的。
