规划：
主备模式，安装ORACLE应用
ORACLE安装在共享非并发卷组datavg上
使用磁盘心跳heartvg
1.1 AIX 6.1
2. 硬件环境
2个AIX分区，配2块网卡
存储一台
先安装AIX系统，并安装以下文件集：
bos.clvm.enh
bos.data
rsct.basic
(rsct.basic.hacmp rsct.basic.sp rsct.basic.rte )
rsct.compat.basic
(rsct.compat.basic.hacmp rsct.compat.basic.rte rsct.compat.basic.sp)
rsct.compat.clients
(rsct.compat.clients.hacmp rsct.compat.clients.rte rsct.compat.clients.sp)
bos.perf.tools
perfagent.tools //加粗的这些默认已安装
bos.adt.syscalls
bos.adt.libm
扩展/usr文件系统，安装ML
3.3 安装POWERHA 6.1
3. 系统环境（2台都要配置）
127.0.0.1 loopback localhost
192.168.0.100 node1_boot （第1块物理网卡IP en0 hostname）
192.168.0.200 node2_boot
192.168.1.100 node1_stdby （第2块物理网卡IP）
192.168.1.200 node2_stdby
192.168.2.100 svc
server ip用来与程序的客户端通信用，主机宕机后，该IP就会从主机飘逸到另外一台备用机器上
该server ip可以是一个，也可以是两个（主备是1个，互备是2个）
3.2 修改/usr/es/sbin/cluster/etc/rhosts文件:（/.rhosts文件为被替代）
node1_boot
node2_boot
node1_stdby
node2_stdby
svc
修改该文件权限为600
Chmod 600 xxx

HACMP软件安装
#smitty install(除cluster.hativoli和cluster.haview不装外，其他全部安装)
以上两台机器都要配置
配置共享卷组
在共享存储上划分LUN给这两条机器，hdisk2。配成非并发卷组datavg
node1:
#smit mkvg
卷组名取datavg
Hdisk2是共享存储
此处需注意卷组的主编号在从机上也未使用，可在/dev/里使用ls -l查看主编号
备机上执行：
node2:
chdev -l hdisk2 -a pv=yes
#importvg -y'datavg' -V'49' hdisk2
增强并发卷组（磁盘心跳）
主节点执行：创建立并发卷组heartvg。该步骤可以在执行4.1.2后操作，否则不出现节点名称
#smitty hacmp -> System Management (C-SPOC)-> Storage-> Volume Groups->
Create a Volume Group?->选中节点，再选择hdisk1，创建磁盘心跳
# lspv
hdisk0 00f74b0737faad79 rootvg active
hdisk1 00f74b073ff9e4d4 heartvg
hdisk2 00f74b073ff3d4b1 datavg active
在第一个节点和第二个节点的/etc/environment的PATH最后加入:/usr/sbin/rsct/bin。
测试磁盘心跳：
重新使用root登录第一节点和第二节点，执行如下命令。出现以下类似情况说明磁盘心跳测试通过。
[dbsvr1]#dhb_read -p hdisk8 -r
DHB CLASSIC MODE
First node byte offset: 61440
Second node byte offset: 62976
Handshaking byte offset: 65024

[dbsvr2]#dhb_read -p hdisk8 -t

查看群集通信守护进程
分别查看2个机器上的/etc/inittab文件的最后几行是否包含以下部分：
clcomdES:2:once:startsrc -s clcomdES >/dev/console 2>&1
主要用于启动Cluster Communications Daemon (clcomd)，这也是在配置HACMP时，运行自动发现过程所需要的。（不一定有，不用管）
…
ctrmc:2:once:/usr/bin/startsrc -s ctrmc > /dev/console 2>&1
ha_star:h2:once:/etc/rc.ha_star >/dev/console 2>&1
hacmp:2:once:/usr/es/sbin/cluster/etc/rc.init >/dev/console 2>&1
自动写的
4. 配置HACMP 以下操作只需在一个节点上操作即可

* Enable IP Address Takeover via IP Aliases [Yes] +
IP Address Offset for Heartbeating over IP Aliases []
* Enable IP Address Takeover via IP Aliases [Yes] 此选项决定了HACMP的IP切换方式，但值得一提的是只有“boot”、“standby”、“service”三个IP分别为三个不同网段时必须选用IP Aliases方式。如果“boot”、“standby”其中一个与“service”为同一个网段时必须选用IP Replace，则此选项应选“NO”。
4.1.3.3 创建磁盘心跳网络
# smitty hacmp
Extended Configuration
Extended Topology Configuration
Configure HACMP Networks
Add a Network to the HACMP Cluster，类型选diskhb
* Network Name [net_diskhb_01]

Extended Resource Configuration
HACMP Extended Resources Configuration
Configure HACMP Applications Servers
Add an Application Server
* Server Name [appserver]
* Start Script [/hascript/clstart.sh]
* Stop Script [/hascript/clstop.sh]
需要先手动在两个节点上建立“/hascript/clstart.sh”、“/hascript/clstop.sh”并保证其有执行权限。如果是双机互备的话需要建立两个App Server。方法相同。

5. 校验并同步HACMP配置
# smitty hacmp
Extended Configuration
Extended Verification and Synchronization
* Verify, Synchronize or Both [Both] +
* Automatically correct errors found during [Interactively] +
verification?
* Force synchronization if verification fails? [No] +
* Verify changes only? [No] +
* Logging [Standard] +
看HA拓扑：
Show Cluster Topology
6. 启动/停止HACMP
6.1 启动HACMP（快速路径：#smitty clstart）
# smitty hacmp
System Management (C-SPOC)
Manage HACMP Services
Start Cluster Services
* Start now, on system restart or both now
Start Cluster Services on these nodes [NodeA NodeB]
* Manage Resource Groups Automatically
BROADCAST message at startup? true
Startup Cluster Information Daemon? false
Ignore verification errors? false
Automatically correct errors found during Interactively
cluster start?
启动完成后，登陆主节点查看资源
# lsvg -o
datavg
rootvg
# l***c -g cluster
Subsystem Group PID Status
clstrmgrES cluster 78092 active
备节点没挂上datavg和启用service ip
6.2 停止HACMP（快速路径：#smitty clstop）
# smitty hacmp
System Management (C-SPOC)
Manage HACMP Services
Stop Cluster Services
* Stop now, on system restart or both now+
Stop Cluster Services on these nodes [NodeA NodeB] +
BROADCAST cluster shutdown? true+
*Select an Action on Resource Groups Move Resource Groups+
7. 测试HACMP（这里仅为模拟测试）
7.1、模拟资源从主切到备
#smitty clstop //主上操作，主的cluster被关闭
再登陆备机，datavg资源起来了，主节点现在看不到
如果要切换回主，使用smit clstart启动主的cluster，这时备上的资源切换回主
7.2、拔网线测试
ifconfig en2 down //模拟主网卡即服务IP所在网卡故障
将主上的主网卡网线拔出，过段时间，服务IP切到主节点的备网卡上
接回网线不切换回来，要手动切
7.3、模拟主机宕机
主节点执行halt模拟宕机，资源切到备上
主节点起来后，手动起ha,资源自动切回来
