怎么样在AIX上安装/卸载Powerpath(for EMC Storage)

1、检查所需要的文件集

Powerpath4.3以上要求devices.pci.df1000f7.com 5.1.0.58以上，devices.fcp.disk.rte 5.2.0.17以上

检查文件集

# lslpp -l devices.pci.df1000f7.com devices.fcp.disk.rte

   Fileset                      Level  State      Description
   ----------------------------------------------------------------------------
   Path: /usr/lib/objrepos
    devices.fcp.disk.rte      5.2.0.60  APPLIED    FC SCSI CD-ROM, Disk,
                                                   Read/Write Optical Device
                                                   Software
    devices.pci.df1000f7.com  5.2.0.60  APPLIED    Common PCI FC Adapter Device
                                                   Software
   Path: /etc/objrepos
    devices.fcp.disk.rte      5.2.0.60  APPLIED    FC SCSI CD-ROM, Disk,
                                                   Read/Write Optical Device
                                                   Software
    devices.pci.df1000f7.com  5.2.0.60  APPLIED    Common PCI FC Adapter Device
                                                   Software

对应的补丁要求（仅仅针对5.2版本）

2、安装agent，先解压agent软件

注意：Agent的软件要求版本最好与存储本身的软件版本一致。

#unzip AIX_NAVIAGNTCLI_619.zip

进去到解压后的目录

# cd AIX_NAVIAGNTCLI_619

IXDBA.NET社区论坛

运行

#smit install_latest

软件列表选择需要安装的naviagent，或者是默认全部（因为本目录下只有agent）

    > NAVIAGENT                                                          ALL
     + 6.19.0.4  Navisphere Disk Array Management Tool (AGENT)           

    > NAVICLI                                                            ALL
     + 6.19.0.4  Navisphere Disk Array Management Tool (CLI)

选择接受许可协议

ACCEPT new license agreements? Yes

回车安装

如果安装成功，将会自动在/etc/inittab中增加

naviagent:2:wait:/etc/rc.agent > /dev/console 2>&1

安装完成后，在启动之前，还需要配置agent

#vi /etc/Navisphere/agent.config

在如下部分增加：
