IBMPowerAIX61+Ha71配置方法
1.说明
1.1.文档说明
本文的环境是在AIX6.1操作系统下安装配置hacmp7.1.1.1的步骤，其它版本的系统安装配置基本类似，不同之处，请参考IBM的官方文档。
1.2.注意事项
配置hacmp的一些注意事项：
1.2.1.安装的版本要符合数据中心的版本策略要求
1.2.2.安装前要做好规划，了解应用要实现什么样的高可靠性需求
1.2.3.HA可以实现排除单点故障，但不是冗余，因此关键部件还要有冗余配置，如电源模块、双HBA卡、rootvg镜像等
1.2.4.配置为HA的主、备节点不能是同一台物理服务器上的两个逻辑分区
1.2.5.存储厂商在HA环境下有定制的磁盘解锁脚本，EMC、HDS存储，在HA的addcustomdiskmethods中增加厂商自定义脚本。
1.2.6.编写的应用启停脚本要事先手工执行测试，并且确保停止脚本在系统异常时可以停止应用，以释放资源。
1.2.7.HA配置完成后，不要将HA的服务设置为自启动模式，即HA服务的启动，要手工启动
1.2.8.HA配置完成后，要模拟各种故障场景，充分测试接管功能是否正常。
