恢复过程中的问题：
1、首先，在root运行rootdelete.sh的脚本时，2个节点运行时间很长大概有半个小时；
2、在为rac数据库划分新LUN时，名称及逻辑rhdiskn对应关系要与故障前保持一致；如果是IBM AIX小型机，在划分LUN后根据存储类型需要在2个节点设置生效参数reserve_policy=no_reserve；否则，在2个节点的RAC的第二个节点运行root.sh时会报如下异常错误：
cp: /dev/rhdiskn: The requested resource is busy.
3、在2个节点的RAC的第二个节点执行完毕root.sh后还需要注册vip、asm（如果RAC采用的是asm存储管理）、database、instance到OCR；在注册vip时需要服务器桌面支持，登录时必须使用oracle用户，否则以root 登录服务器su到oracle，在执行vipca时无法启动图形桌面。

记得要使用RMAN进行全库备份，避免仲裁盘恢复失败数据丢失，用以RAC重建恢复。
故障模拟
[oracle@rac10gnode1 ~]$ dd if=/dev/zero of=/dev/raw/raw2 bs=8k count=4k
Connection closed by foreign host.
可以看到当仲裁盘被破坏后，2台RAC集群服务器同时自动重启
重启后可以查看RAC集群的状态，已经看不到crs和votedisk了
[oracle@rac10gnode1 bdump]$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
接下来是votedisk重建过程
首先删除原有的CRS和votedisk的配置
[root@rac10gnode1 ~]# cd /oracle/app/oracle/product/10.2.0.1/crs/install
[root@rac10gnode1 install]# ./rootdelete.sh

检查是否还有ocr、crs、evm进程存在
[root@rac10gnode1 install]# ps -e | grep -i 'ocs[s]d'
[root@rac10gnode1 install]# ps -e | grep -i 'cr[s]d.bin'
[root@rac10gnode1 install]# ps -e | grep -i 'ev[m]d.bin'
接下来是重建votedisk和ocr的过程，这里使用原先的ocr和votedisk裸设备，生产中可能需要重新划分votedisk和ocrLUN，需要注意reserve_policy参数的设置；另外，需要使用root用户到两个节点crs目录执行root.sh
[root@rac10gnode1 crs]# ./root.sh

这里有报错，是因为vip网口没有配置，接下来配置vip
[root@rac10gnode1 crs]# su - oracle
[oracle@rac10gnode1 ~]$ oifcfg setif -global eth1/192.168.56.0:public
[oracle@rac10gnode1 ~]$ oifcfg setif -global eth0/10.10.10.0:cluster_interconnect
[oracle@rac10gnode1 ~]$ oifcfg iflist
eth0 10.10.10.0
eth1 192.168.56.0
[oracle@rac10gnode1 ~]$ oifcfg getif
eth1 192.168.56.0 global public
eth0 10.10.10.0 global cluster_interconnect
然后使用root用户到/oracle/app/oracle/product/10.2.0.1/crs/bin目录下运行vipca
配置VIP
vip配置完成后就可以查看RAC集群的状态了
[root@rac10gnode1 bin]# su - oracle
[oracle@rac10gnode1 ~]$ crs_stat -t
