三、卸载后检查确认
1、检查每个节点上的输出日志，确认无误。
2、检查各个节点的/etc/inittab文件，ohasd的内容应该被删除了。
3、检查每个节点是否存在ora或d.bin的进程运行，有即kill掉。
4、检查/etc/oracle目录，确认这个目录下的.loc文件被命名为.orig.
5、删除$GRID_HOME和$ORACLE_HOME目录。

总结：卸载步骤
1、[root@node1 bin]# pwd
/u01/app/11.2.0/grid/bin
[root@node1 bin]# ./crsctl stop crs
2、[root@node2 bin]# pwd
/u01/app/11.2.0/grid/bin
[root@node2 bin]# ./crsctl stop crs
3、[grid@node1 grid]$ cd /u01/app/11.2.0/grid/deinstall/
[grid@node1 deinstall]$ ./deinstall
4、卸载后检查确认
1）检查每个节点上的输出日志，确认无误。
2）检查各个节点的/etc/inittab文件，ohasd的内容应该被删除了。
3）检查每个节点是否存在ora或d.bin的进程运行，有即kill掉。
4）检查/etc/oracle目录，确认这个目录下的.loc文件被命名为.orig.
5）删除$GRID_HOME和$ORACLE_HOME目录。
5、删除asm磁盘
