HACMP软件的配置
北京地税大楼S70系统ＨＡＣＭＰ配置图如下，其中en0,en2为双网卡。S70a主机为业务主机，S70b主机为业务备机，另有7133磁盘阵列。
首先进行HACMP配置的准备工作：

5.3 HACMP软件的测试
1.HACMP测试步骤
(1)节点接管测试
1)启动Node1及Node2的HACMP软件
2)在Node1:
- 用指令"netstat -i"检查IP address,确认主网卡使用service IP adress,
备用网卡使用standby IP address.
- 用指令"lsvg -o"检查vary on 的VG.
- 用指令"df"检查mount的文件系统.
- 确认属于Node1的online应用正常.

3)在Node2:

备用网卡使用standby IP address.
- 用指令"lsvg -o"检查vary on 的VG.
- 用指令"df"检查mount的文件系统.
- 确认属于Node2的online应用正常(如果存在).

4)在Node1:
- 用指令"smit clstop",选择Takeover方式停止node1的HACMP并使node2接管.(另一种方式是直接按node1的reset键使其reboot.)

5)在Node2:
- 等待接管过程完全结束.
- 用指令"netstat -i"检查IP address,确认node1 的service IP adress已被备用网卡接管.

5.4 HACMP软件的简明使用指南
1.启动HACMP之前
- 运行指令"netstat -i"检查IP address,确认主网卡使用boot IP adress,
备用网卡使用standby IP address.
- 运行指令"lsvg -o"检查vary on 的VG,确认共享VG为varyoff状态.
- 确认无其他节点正在启动HACMP.

2.启动HACMP
- 运行指令"smit clstart"回车. 等待命令执行OK,退出smit.
- 等待HACMP完全启动,可用指令"tail -f /tmp/hacmp.out"观察HACMP启动
状况.
- 用指令"netstat -i"检查IP address,确认主网卡使用service IP adress,
备用网卡使用standby IP address.
- 用指令"lsvg -o"检查vary on 的VG,确认共享VG变为varyon状态.
- 用指令"df"检查mount的文件系统.
- 确认属于Node1的online应用正常.

3.停止HACMP
- 运行指令"smit clstop"回车.在shutdown mode项选择graceful并回车, 等待命令执行OK,退出smit.
- 等待HACMP完全停止,可用指令"tail -f /tmp/hacmp.out"观察HACMP停止状况.
- 用指令"netstat -i"检查IP address,确认主网卡变为boot IP adress,
备用网卡使用standby IP address.
- 用指令"lsvg -o"检查vary on 的VG,确认共享VG变为varyoff状态.

4.人为接管HACMP
在某些维护情况下,需将某节点的HACMP及应用切换至另一节点.
- 运行指令"smit clstop"回车.在shutdown mode项选择takeover并回车, 等待命令执行OK,退出smit.
- 等待HACMP完全停止,可用指令"tail -f /tmp/hacmp.out"观察HACMP停止状况.
- 用指令"netstat -i"检查IP address,确认主网卡变为boot IP adress,
备用网卡使用standby IP address.
- 用指令"lsvg -o"检查vary on 的VG,确认共享VG变为varyoff状态.
- 在另一节点运行相同命令,确认网卡,VG及应用接管成功
