一、环境描述
（1）Oracle 11.2.0.3 RAC ON Oracle Linux 6 x86_64，只有一个ASM外部冗余磁盘组——DATA；
（2）OCR，VOTEDISK，DATAFILE，CONTROLFILE，SPFILE全部位于这个磁盘组上；
二、故障描述
（1）存储故障导致ASM磁盘丢失。
（2）CRS因为OCR和VOTEDISK的丢失，除了OHAS还联机外，CLUSTERWARE服务都已经停止。
三、备份情况
（1）RMAN备份：包括controlfile，database，spfile，archivelog，
（2）OCR备份：没有进行过人工备份，在$CRS_HOME/cdata目录下有CRS自动备份文件。
四、操作步骤
说明：准使用CRS自动备份的文件恢复OCR，使用RMAN备份来恢复数据库；准备恢复数据的同时，调整ASM磁盘组，将OCR，VOTEDISK同数据库文件分开存放。
4.1 恢复OCR和VOTEDISK
(1) 在所有RAC节点上停止CRS服务

(2) 在一个节点上以NOCRS方式启动CRS，此操作会启动ASM实例。

(3) 新添加了三块磁盘，已经使用UDEV进行了绑定，查看磁盘状态。

(5) 准备恢复OCR和VOTEDISK，/etc/oracle/ocr.loc中记录了OCR路径，修改ocrconfig_loc的值，以便将OCR恢复到新的磁盘组中。
[[email protected] ~]# more /etc/oracle/ocr.loc
ocrconfig_loc=+DATA

[[email protected] ~]# vi /etc/oracle/ocr.loc

(6) 恢复OCR

(2) 更改CRS配置文件中数据库的磁盘组为DATADG和ARCLOGDG
[[email protected] ~]# srvctl modify database -d csdb -a "DATADG,ARCLOGDG"
(3) 禁用并删除原来的磁盘组DATA

(4) 在OCR注册表中修改Oracle数据库参数文件的位置
[[email protected] ~]# srvctl modify database -d csdb -p +DATADG/csdb/spfilecsdb.ora
4.3 恢复数据库
(1) 查看备份文件路径和名称
[[email protected] ~]# su - oracle

[[email protected] ~]$ cd /u01/app/oracle/backup
[[email protected] backup]$ ll

(2) 创建一个基本的启动参数文件，以便启动数据库到nomout状态恢复spfile
[[email protected] ~]$ touch /u01/app/oracle/backup/init.ora
[[email protected] ~]$ vi /u01/app/oracle/backup/init.ora
.db_name=‘csdb‘
.remote_login_passwordfile=‘exclusive‘
(3) 使用刚创建的参数文件将数据库启动到nomount状态

4.4 完成恢复操作
(1) 在其他RAC节点上更改OCR路径
[[email protected] ~]# vi /etc/oracle/ocr.loc
ocrconfig_loc=+SYSTEMDG
local_only=FALSE
(2) 在恢复节点上重启CRS
[[email protected] ~]# crsctl stop crs
[[email protected] ~]# crsctl start has
(3) 在其他节点上启动CRS
[[email protected] ~]# crsctl start crs
