在Oracl RAC 10.2.0.4 两个节点，操作系统为Linux 的环境中，一节点服务器的本地硬盘突然全部损坏，停止运行。剩下的一个节点还能正常工作，继续提供对外数据库服务。
问题很清楚，硬盘损坏的服务器在操作系统重做后，如何添加到RAC 集群中去？
在Google 以及METALINK 上查了一下，倒是有完全一样的问题，但没有想要的答案。

I appreciate any help, and I'm greatful for your time.
（老外有点比较好，最后都是感谢的话。）
有人给出这样的解决方法:
[root@webrac1 crs_1]# more root.sh
#!/bin/sh

/u01/app/oracle/product/10.2.0/crs_1/install/rootconfig
[root@webrac1 crs_1]# ./root.sh

第六步，修改配置文件/etc/oratab
这个文件从幸存节点拷贝过来，修改一下属性和内容。
[root@webrac2 archivelog]# scp /etc/oratab webrac1:/etc/
root@webrac1's password:
oratab
100% 766 0.8KB/s 00:00
[root@webrac2 archivelog]#
[root@webrac1 etc]# chown -R oracle:root oratab
[root@webrac1 etc]# ls -ltr oratab
-rw-r--r-- 1 oracle root 766 05-08 17:12 oratab
[root@webrac1 etc]# vi oratab
#
+ASM1:/u01/app/oracle/product/10.2.0/db_1:N
webdb:/u01/app/oracle/product/10.2.0/db_1:N
~
第七步，执行RDBMS 下的root.sh
[root@webrac1 db_1]# ./root.sh
Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/10.2.0/db_1
Enter the full pathname of the local bin directory: [/usr/local/bin]:
Copying dbhome to /usr/local/bin ...
Copying oraenv to /usr/local/bin ...
Copying coraenv to /usr/local/bin ...
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
第八步，修改配置文件$ORACLE_HOME/network/admin
