7.设置用户的环境变量：
grid用户：

# vim ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
?

?PATH=$PATH:$HOME/bin
?

?export PATH
?

?export ORACLE_BASE=/oracle/app/grid
?export ORACLE_HOME=/oracle/app/11.2.0/grid
?export ORACLE_SID=+ASM2
?export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
?export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
?export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch
?export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
?export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin
?export ORACLE_TERM=xterm
?export LD_LIBRARY_PATH=$ORACLE_HOME/lib
?export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
?export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
?export CLASSPATH=$ORACLE_HOME/JRE
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
?export THREADS_FLAG=native
?export TEMP=/tmp
?export TMPDIR=/tmp
?umask 022
?export TMOUT=0

oracle用户：

#vim ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
?

?PATH=$PATH:$HOME/bin
?

?export PATH
?

?export ORACLE_BASE=/oracle/app/oracle
?export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
?export ORACLE_SID=test
?export LANG=en_US.UTF-8

?export NLS_LANG=american_america.ZHS16GBK
?export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
?export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch
?export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
?export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin:/home/oracle/run
?export ORACLE_TERM=xterm
?export LD_LIBRARY_PATH=$ORACLE_HOME/lib
?export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
?export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
?export CLASSPATH=$ORACLE_HOME/JRE
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
?export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
?export THREADS_FLAG=native
?export TEMP=/tmp
?export TMPDIR=/tmp
?export GI_HOME=/oracle/app/11.2.0/grid
?export PATH=${PATH}:$GI_HOME/bin
?export ORA_NLS10=$GI_HOME/nls/data
?umask 022
?export TMOUT=0
?
8.配置UDEV：

以下操作需要2个节点都执行：

# cd /etc/udev/rules.d
# vim 99-oracle-asmdevices.rules
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="364862761000560eb82f364f700000014", NAME="asmdisk001", OWNER="grid", GROUP="asmadmin", MODE="0660"
其中RESULT的值为磁盘的UUID
获取磁盘UUID的命令如下：
# scsi_id --whitelisted --replace-whitespace --device=/dev/sdb
建议使用脚本将所有磁盘的UUID输出到x.log，然后使用列编辑搞定所有asm磁盘
?./test.sh > x.log
?
执行并核对完99-oracle-asmdevices.rules后，便可以执行命令启动udev了：

# ./sbin/start_udev
# ls -al /dev/asm*
brw-rw---- 1 grid asmadmin 8, 16 Aug 7 14:57 /dev/asmdisk001

9.安装cvudisk包

# cd $INSTALL_MEDIA/grid/rpm/
## CVUQDISK_GRP=oinstall;export CVUQDISK_GRP? --可以在此处自定义安装用户组
