下面是相关详细内容
<!--[if !supportLists]--> <!--[endif]-->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
<!--[if !supportLists]--> <!--[endif]-->启动 HACMP 方法
smit clstart 启动 HA
<!--[if !supportLists]--> <!--[endif]-->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）
<!--[if !supportLists]--> <!--[endif]-->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
<!--[if !supportLists]--> <!--[endif]-->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
<!--[if !supportLists]--> <!--[endif]-->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
<!--[if !supportLists]--> <!--[endif]-->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 cursor to desired item and press Enter.

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
