HBA卡的WWN有两种：
Node WWN（WWNN）：每个HBA卡有其独有的Node WWN。
Port WWN（WWPN）：HBA卡上每个port有其独一无二的Port WWN。
通讯是通过port进行的，多数情况下需要使用WWPN而不是WWNN。
在AIX系统中HBA卡对应的设备是fcs。
先通过lsdev获取系统中识别有几块HBA卡；
# lsdev -C | grep fcs
fcs0 Available 00-08 FC Adapter
fcs1 Available 05-08 FC Adapter
即有两块HBA卡，对应的AIX系统中为fcs0，fcs1；
再使用lscfg命令获取各个HBA卡属性；
# lscfg -vl fcs0
fcs0 U787B.001.DNWGXVH-P1-C3-T1 FC Adapter
