located 1 votedisk(s).

查询asm盘符位置

引用

PATH          NAME
------------  --------------------
/dev/raw/raw2
/dev/raw/raw3 DATADG_0000
/dev/raw/raw4 DATADG_0001

双节点关闭crs

双节点执行以下脚本

引用

rm /etc/oracle/*
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
rm -rf /etc/oratab

双节点杀以下进程

引用

ps -ef | grep crs
kill
ps -ef | grep evm
kill
ps -ef | grep css
kill

双节点删除以下目录，如果存在的话                              

引用

rm -f /var/tmp/.oracle/*                        
rm -f /tmp/.oracle/*
rm -f /etc/oracle/ocr.loc

单节点清空ocr，vot，asm盘
