2.以root用户身份，运行smitty remove命令，删除所有“cluster.”文件集。
（注意：如果是在非SP节点的AIX4.3.3的操作系统上，则也可以删除所有“rsct.”文件集。）

6.如果系统中设置了网络文件系统，那么以root用户身份，运行smitty nfs命令，设置定义的网络文件系统在系统启动时被共享出去或者是被mount上。

5.以root用户身份，运行smitty chfs命令，设置每个节点所拥有的文件系统在系统启动时自动被mount上。
下面是卸装HACMP软件的具体步骤：
1.在每个HACMP节点上以graceful方式停止掉HACMP服务：
a.以root用户身份，运行smitty clstop命令，在两个HACMP节点上以graceful方式停止掉HACMP服务。
# smitty clstop
Stop Cluster Services
9.在每个HACMP节点上，如果.rhosts文件不再被需要，删除该文件。

怎样卸载HACMP软件
本文介绍了在AIX操作系统上如何卸装已安装配置好的HACMP软件。
在使用后面的步骤卸装HACMP软件之前，收集所有下面命令执行后的输出，以确定HACMP软件中定义了哪些资源。
（1）# usrsbinclusterutilitiescllsif 或者 # usressbinclusterutilitiescllsif
Esc+9=Shell Esc+0=Exit Enter=Do
b.确认在HACMP中定义的所有资源，如IP标识、文件系统、卷组、应用服务等都已被停止。
c.以root用户身份，运行lssrc -g cluster命令检查HACMP软件服务进程已被停止。
# lssrc -g cluster

4.以root用户身份，运行smitty chvg命令，设置每个节点所拥有的卷组在系统启动时自动被激活。
# smitty chvg

（4）# usrsbinclusterutilitiescllscustom 或者 # usressbinclusterutilitiescllscustom
如果在usrsbincluster或者usressbincluster目录中有定制的事件，应用服务的启动停止脚本或者是HA群集的快照文件，那么建议将这些文件移至另外一个目录，以保证在卸装HACMP软件时不会删除掉这些文件。
Esc+5=Reset Esc+6=Command Esc+7=Edit Esc+8=Image
Esc+9=Shell Esc+0=Exit
7.配置应用服务在系统启机时被启动，例如，可以在文件etcinittab中增加有应用服务启动脚本的一行。
8.在每个HACMP节点上，清除etchosts文件中不再使用的有关boot地址标识的内容。
Esc+9=Shell Esc+0=Exit Enter=Do
3.以root用户身份，运行smitty chinet命令，设置每个节点以service IP地址引导。
# smitty chinet
