下面是相关详细内容
l 如何检查AIX HA 子系统的状态方法
# lssrc -s clstrmgrES
Subsystem Group PID Status
clstrmgrES cluster 4326122 active
# set -o vi
# lssrc -ls clstrmgrES
Current state: ST_STABLE
sccsid = "@(#)36 1.135.5.2 src/43haes/usr/sbin/cluster/hacmprd/main.C, hacmp.pe, 53haes_r550, 0934B_hacmp550 8/8/09 14:48:23"
i_local_nodeid 0, i_local_siteid -1, my_handle 1
ml_idx[1]=0
There are 0 events on the Ibcast queue
There are 0 events on the RM Ibcast queue
CLversion: 10
local node vrmf is 5506
cluster fix level is "0"
The following timer(s) are currently active:
Current DNP values
DNP Values for NodeId - 0 NodeName - sc1prrhas01
PgSpFree = 0 PvPctBusy = 0 PctTotalTimeIdle = 0.000000
DNP Values for NodeId - 0 NodeName - sc1prrhas02
PgSpFree = 0 PvPctBusy = 0 PctTotalTimeIdle = 0.000000
Current state: ST_STABLE 表明CLUSTER 已经正常
Current state: ST_BARRIER 表明 正在启动操作中
Current state: ST_INIT 两边cluster都停止的时候，虽然subsystem启动但是状态是这个
l 启动HACMP方法
smit clstart 启动 HA
l 关闭HACMP方法，smitty clstop 停止Cluster 操作（要逐台操作，比如P1,P2两台AIX做cluster要确认等P1的HACMP关闭之后才能，去关闭P2的HACMP）
l hacmp的log文件位置
# pwd
/var/hacmp/log
# ls hacmp.out
hacmp.out
该目录下如下是系统自动备份的文件
hacmp.out.1
hacmp.out.2
hacmp.out.3
hacmp.out.4
hacmp.out.5
hacmp.out.6
hacmp.out.7
l 操作两台做HA 的AIX操作建议：推荐开4个窗口 2个用tail –f 命令查看hacmp log 另外2个窗口执行命令
l 查看hacmp 状态方法 运行smit hacmp选择

P1,P2上3个 res ，如果只切换其中一个res 可以在上面按res查看 那个节点该res状态 是online还是offline
l HA的验证smit hacmp

运行smit hacmp选菜单：
System Management (C-SPOC)
HACMP Resource Group and Application Management
Move a Resource Group to Another Node / Site
Move Resource Groups to Another Node
再选中res进行操作
上面move res操作不限制，在任何cluter上的节点上都能操作（需要team人沟通同时只有一个人进行该操作，避免互相干扰）

下面选择一个其中res ，选择之后按执行如下 会让选择Select a Destination Node由于公司P1,P2 HA 就两个节点，当下选择另外一个服务节点名sc1prrhas02没有其他选项，后面画面，显示res名和节点名，再按确认才开始运行
Move a Resource Group to Another Node / Site
Move cursor to desired item and press Enter.

运行完成之后如下显示，按翻页键会log里显示这个cluster里所有res的当前在服务器上状态

l Bring a Resource Group Online， Bring a Resource Group Offline和Move a Resource Group to Another Node / Site区别：
move res总在ha的一个node里online 而Bring 一个res offline吧res 在所有节点上offline，比如res是vg的话，bring res offline后res里指定vg在所有ha中服务器节点都varryoff不可用
