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
① 查看AIX主机连接的光纤设备
fcs0 Available 06-08 FC Adapter
fcs1 Available 0A-08 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
