红色部分为需要增加的部分

3、安装powerpath ODM补丁

# zcat EMC.AIX.5.2.0.3.tar.Z| tar -xvf -

x ./README.5203, 21598 bytes, 43 media blocks.

x ./EMC.AIX.5.2.0.3, 15360000 bytes, 30000 media blocks.

#smit install_latest

选择安装软件列表或者是全部（假定本目录下只有该补丁）

    > EMC                                                                ALL
       5.2.0.3  EMC CLARiiON Fibre Channel Support Software
       5.2.0.3  EMC CLARiiON HA Concurrent Support
       5.2.0.3  EMC Symmetrix AIX Support Software
       5.2.0.3  EMC Symmetrix Fibre Channel MPIO Support Software
       5.2.0.3  EMC Symmetrix Fibre Channel Support Software
       5.2.0.3  EMC Symmetrix HA Concurrent Support  

如果在Symmetrix或者是CLARiiON不足的环境，可能会包安装错误，根据实际环境决定这个错误是否有影响，如有Symmetrix，CLARiiON的安装则会报错，反之一样。

如果在非ha的环境下，EMC.Symmetrix.ha.rte与EMC.CLARiiON.ha.rte也可能会出现安装错误，如果是非ha就没有关系的了。

如一般在单机情况下使用Clariion存储，如cx700,cx3-80等等，只需要安装第一个文件集即可。

4、安装powerpath

#gunzip EMCpower.AIX.4.5.1.tar.gz

# tar xvf EMCpower.AIX.4.5.1.tar

x EMCpower_install, 9830400 bytes, 19200 media blocks.

#smit install_latest

安装目录选择本目录

软件列表选择Powerpath或者是全部（本目录下只有powerpath）

    >EMCpower                                                           ALL
       4.5.1.0  PowerPath Base Driver and Utilities
       4.5.1.0  PowerPath Consistency Group Extension and Utilities
       4.5.1.0  PowerPath HighRoad Extension and Utilities
       4.5.1.0  PowerPath Multi_Pathing Extension and Utilities
       4.5.1.0  PowerPath Multi_Pathing Extension for Active Active
       4.5.1.0  PowerPath Multi_Pathing Extension for Active Passive
       4.5.1.0  PowerPath Multi_Pathing Extension for Clariion 

回车，接受协议，开始安装。

安装完成后，在/etc/inittab中，会增加一行

rcemcpower:2:wait:/etc/rc.emcpower set_ipldevice > /dev/console 2>&1

安装之后，需要输入序列号

#emcpreg -install 输入powerpath序列号

以下是powerpath的管理命令

# powercf -q

#powermt config 产生Emcpower设备

#powermt display dev=all 查看所有Emcpower设备及状态

IXDBA.NET技术社区

#powermt display paths 查看光纤卡到EMC的路径

注意：先安装odm补丁，再安装powerpath，安装完成后需要重新启动一下。

安装过的补丁与powerpath可以通过如下命令查看

# lslpp -l EMC*
