vcs应用启停挂载目录数据的收获
注意在执行后台命令的时候。在监控IO的时候不能确认是否有小IO读写，不要中断屏幕；否则会导致命令执行无效：
Host02# cp -r -p /orahome /host02backup &
21201
extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t%w%b device

^C+ 终止 cp -r -p /orahome /mnt/host02
建议实时用短时间监控一下。不要用长时间监控IO。
一：停止vcs上的应用的正常操作如下：
Host01# hagrp -offline weblogic -sys Host01
Host01# hastatus -sum
-- SYSTEM STATE
-- System State Frozen
AHost01 RUNNING 0
AHost02 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
Boracle9i Host01 Y N OFFLINE
Boracle9i Host02 Y N ONLINE
Bweblogic Host01 Y N ONLINE|STOPPING
Bweblogic Host02 Y N OFFLINE
-- RESOURCES OFFLINING
-- Group Type Resource System IState
Fweblogic VProWebLogic weblogic Host01 W_OFFLINE_PROPAGATE
最终状态:
Host02# hastatus -sum
-- SYSTEM STATE
-- System State Frozen
AHost01 RUNNING 0
AHost02 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
Boracle9i Host01 Y N OFFLINE
Boracle9i Host02 Y N OFFLINE
Bweblogic Host01 Y N OFFLINE
Bweblogic Host02 Y N OFFLINE
二：如果要copy vcs控制的挂载点上的数据正确的操作是冻结节点的资源在拷贝数据
当我手动挂载磁盘资源的时候；在vcs状态中会报如下的错误：
Host01# mount -F vxfs /dev/dsk/c4t200400A0B80F7111d4s6 /beahome
Host01# df -k

正确操作：
冻结资源：将oracle9i资源冻结在主机Host02上；不让它切换。
Host02#haconf -makerw[如果在该系统上已经执行了该命令；会出现如下的报错]
