PowerVM 存储特性NPIV实例介绍：

PowerVM 存储特性NPIV实例介绍：

首先检查 SAN 光纤交换机是否支持 NPIV 特性，如果必要更新交换机微码，本例使用一台支持 NPIV 的 IBM 2498 B24 光纤交换机。
以下 portcfgshow 命令检查光纤交换机是否支持 NPIV 特性：

接着检查 Power6 机器的相关属性，确保该机器支持 NPIV 功能，
本例通过 HMC 来显示一台机器的属性，选项“Virtual Fibre Channel Capable”显示为”True”, 代表该机器符合硬件要求, 

 查看WWPN

在 VIOS 上执行 lsdev – dev vfchost* 命令查看虚拟光纤卡 , 列出所有的已定义的虚拟光纤卡

$ lsdev -dev vfchost* 

 name             status      description 

 vfchost0         Available   Virtual FC Server Adapter

接着执行 lsdev 命令查看所有的物理光纤卡 , 列出所有的物理虚拟光纤卡

 $ lsdev -dev fcs* 

 name   status            description 

 fcs0   Available       4Gb FC PCI Express Adapter (df1000fe) 

 fcs1   Available       4Gb FC PCI Express Adapter (df1000fe) 

 fcs2 Available     8Gb PCI Express Dual Port FC Adapter (df1000fl14108a03) 

 fcs3 Available     8Gb PCI Express Dual Port FC Adapter (df1000fl14108a03) 

执行 lsnports 命令查看所有可以适用于 NPIV 的端口

$ lsnports 

 name physloc                   fabric      tports aports swwpns awwpns 

 fcs3 U7830.001.DMDYKYM-P1-C6-T2      1        64         63      2048     2046 

最后执行 lsmap -npiv -all 命令查看映射的结果

 $ lsmap -npiv -all
