如何查看wwwn号
FC HBA，也即Fibre Channel Host Bus Adapter，光纤通道主机适配器，简称光纤适配器。
在FC网络环境中，主机需要和FC网络、FC存储设备（SAN磁盘阵列）连接时需要使用一种接口卡，就如同连接以太网需要以太网卡一样，这种接口卡就叫做FC HBA，简称FC HBA卡。
和以太网卡的MAC地址一样，HBA上也有独一无二的标识，：WWN（World Wide Name），FC HBA上的WWN有两种：
① Node WWN（WWNN）：每块HBA有其独有的Node WWN；
② Port WWN（WWPN）：每块HBA卡上每个port有其独一无二的Port WWN。
由于通信是通过port进行的，因此多数情况下需要使用WWPN而不是WWNN。 WWN的长度为8bytes，用16进制表示并用冒号分隔，例如：50:06:04:81:D6:F3:45:42
RedHatLinux as4和Linux as5下查看的地方不一样：
RedHatLinux as4下查看：
cat /proc/scsi/qla2xx/1
RedHatLinux as5下查看：
cd /sys/class/fc_host/hostx/1
[root@host1]# cat node_name
0x20000000c97084q4 --WWNN号
[root@host1]# cat port_name
0x10000000c97084q4 --WWPN号

查看HBA名和数量,有两个命令都可以查看得到：
prtconf和lsdev命令：
# prtconf|grep fc
+ fcs2 U7879.001.DQD629X-P1-C5-T1 FC Adapter
* fcnet2 U7879.001.DQD629X-P1-C5-T1 Fibre Channel Network Protocol

+ fcs0 U7879.001.DQD630D-P1-C2-T1 FC Adapter
* fcnet0 U7879.001.DQD630D-P1-C2-T1 Fibre Channel Network Protocol
Device
# lsdev -Cc adapter|grep fcs
fcs0 Available 0F-08 FC Adapter
fcs1 Available 0G-08 FC Adapter
fcs2 Available 0H-08 FC Adapter
查看HBA卡WWN号，这里也可以用两具命令：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：
