AIX 光纤卡相关

光纤卡可以用来干嘛？
  连接光纤交换机，然后与同样连在交换机上的storage或者是备份的带库相连，并直接使用storage上划出的lun或者是使用LAN free直接通过TSM带库来备份数据库或者文件系统；
  当然另外一种就是主机上的光纤卡直接连接到storage的光纤口，这多用在高端存储中，这样可以获得更好的数据传输性能，并且可以减少故障点以保证高可用性。

怎么查看主机上是否有光纤卡？
AIX下面可以使用以下命令来获得插在主机上光纤卡的信息
#lscfg |grep fcs
+ fcs1             U7879.001.DQD2L9P-P1-C1-T1                    FC Adapter
+ fcs0             U7879.001.DQD2L9P-P1-C3-T1                    FC Adapter
+ fcs2             U7879.001.DQD2L9P-P1-C6-T1                    FC Adapter

#lsdev -Cc adapter
fcs0      Available 06-08 FC Adapter
fcs1      Available 0C-08 FC Adapter
fcs2      Available 09-08 FC Adapter

可以看到在上面这台主机上有三块光纤卡，现在来看这些光纤卡插在那个PCI插槽上的
#lsslot -c pci
U7879.001.DQD2L9P-P1-C1  PCI-X capable, 64 bit, 133MHz slot  fcs1
U7879.001.DQD2L9P-P1-C2  PCI-X capable, 64 bit, 133MHz slot  sisscsia1
U7879.001.DQD2L9P-P1-C3  PCI-X capable, 64 bit, 133MHz slot  fcs0
U7879.001.DQD2L9P-P1-C4  PCI-X capable, 64 bit, 133MHz slot  sa0
U7879.001.DQD2L9P-P1-C5  PCI-X capable, 64 bit, 133MHz slot  ent2
U7879.001.DQD2L9P-P1-C6  PCI-X capable, 64 bit, 133MHz slot  fcs2
可以看到fcs0, fcs1, fcs2分别插在P1-C3, P1-C1, P1-C6这些槽位上

再来查看光纤卡的Network Address即它的WWN号
#lscfg -vpl fcs0

当我们查询某个hdisk的属性的时候，如果它是storage上面的，那么我们可以看到接storage的光纤卡是哪一块，如以下例子
#lscfg -vpl hdisk70
  hdisk70          U7879.001.DQD2L9P-P1-C3-T1-W50060E8005B0CC10-L10000000000000  Hitachi Disk Array (Fibre)
