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

[root@rac1 ~]# crsctl stop has -f

CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac1'

CRS-2673: Attempting to stop 'ora.mdnsd' on 'rac1'

CRS-2677: Stop of 'ora.gipcd' on 'rac2' succeeded

CRS-2673: Attempting to stop 'ora.gpnpd' on 'rac2'

CRS-2677: Stop of 'ora.gpnpd' on 'rac2' succeeded

CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'rac2' has completed

CRS-4133: Oracle High Availability Services has been stopped.

(2) 在一个节点上以NOCRS方式启动CRS，此操作会启动ASM实例。

[root@rac1 ~]# crsctl start crs -excl -nocrs

CRS-4123: Oracle High Availability Services has been started.

CRS-2672: Attempting to start 'ora.mdnsd' on 'rac1'

CRS-2676: Start of 'ora.mdnsd' on 'rac1' succeeded

CRS-2672: Attempting to start 'ora.gpnpd' on 'rac1'

CRS-2676: Start of 'ora.gpnpd' on 'rac1' succeeded

CRS-2672: Attempting to start 'ora.cssdmonitor' on 'rac1'

CRS-2672: Attempting to start 'ora.gipcd' on 'rac1'

CRS-2676: Start of 'ora.cssdmonitor' on 'rac1' succeeded

CRS-2676: Start of 'ora.gipcd' on 'rac1' succeeded

CRS-2672: Attempting to start 'ora.cssd' on 'rac1'

CRS-2672: Attempting to start 'ora.diskmon' on 'rac1'

CRS-2676: Start of 'ora.diskmon' on 'rac1' succeeded

CRS-2676: Start of 'ora.cssd' on 'rac1' succeeded

CRS-2679: Attempting to clean 'ora.cluster_interconnect.haip' on 'rac1'

CRS-2672: Attempting to start 'ora.ctssd' on 'rac1'

CRS-2681: Clean of 'ora.cluster_interconnect.haip' on 'rac1' succeeded

CRS-2672: Attempting to start 'ora.cluster_interconnect.haip' on 'rac1'

CRS-2676: Start of 'ora.ctssd' on 'rac1' succeeded

CRS-2676: Start of 'ora.cluster_interconnect.haip' on 'rac1' succeeded

CRS-2672: Attempting to start 'ora.asm' on 'rac1'

CRS-2676: Start of 'ora.asm' on 'rac1' succeeded

(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。

[root@rac1 ~]# su - grid

[grid@rac1 ~]$ sqlplus / as sysasm

SQL> select group_number group#, disk_number disk#, OS_MB, state, path, header_status from v$asm_disk order by 1,2;

GROUP#      DISK#      OS_MB STATE      PATH                 HEADER_STATUS


     0          0       1024 NORMAL     /dev/asm-diskc       CANDIDATE

     0          1       5120 NORMAL     /dev/asm-diskd       CANDIDATE

     0          2      20480 NORMAL     /dev/asm-diskb       CANDIDATE

(4) 创建三个磁盘组，SYSTEMDG给CRS使用，用于存放OCR，VOTEDISK和ASM实例的SPFILE。其余两个给ORACLE使用，DATADG用于存放datafile，controlfile，redolog，spfile；ARCLOGDG存放archivelog。

SQL> create diskgroup SYSTEMDG external redundancy

2 disk '/dev/asm-diskc'

3 ATTRIBUTE 'compatible.rdbms' = '11.2','compatible.asm' = '11.2';

SQL> create diskgroup DATADG external redundancy

2 disk '/dev/asm-diskb'

3 ATTRIBUTE 'compatible.rdbms' = '11.2','compatible.asm' = '11.2';

SQL> create diskgroup ARCLOGDG external redundancy

2 disk '/dev/asm-diskd'

3 ATTRIBUTE 'compatible.rdbms' = '11.2','compatible.asm' = '11.2';

(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。

[root@rac1 ~]# more /etc/oracle/ocr.loc

ocrconfig_loc=+DATA

local_only=FALSE

[root@rac1 ~]# vi /etc/oracle/ocr.loc

ocrconfig_loc=+SYSTEMDG

local_only=FALSE

(6) 恢复OCR

[root@rac1 ~]# ocrconfig -showbackup

PROT-26: Oracle Cluster Registry backup locations were retrieved from a local copy

rac1 2013/07/05 12:30:00 /u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr

rac1 2013/07/05 00:29:59 /u01/app/11.2.0/grid/cdata/rac-cluster/week.ocr

PROT-25: Manual backups for the Oracle Cluster Registry are not available

[root@rac1 ~]# ocrconfig -restore /u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr

[root@rac1 ~]# ocrcheck

Status of Oracle Cluster Registry is as follows :

(7) 创建VOTEDISK

[root@rac1 ~]# crsctl replace votedisk +SYSTEMDG

CRS-4602: Failed 27 to add voting file afb0ca0f35684f1abfd43d5ec2dc1123.

Failed to replace voting disk group with +SYSTEMDG.

CRS-4000: Command Replace failed, or completed with errors.

以上报错是因为使用UDEV绑定ASM磁盘时需要更改默认磁盘搜索路径为/dev/asm*，修改ASM磁盘搜索路径

[root@rac1 ~]# su - grid

[grid@rac1 ~]$ sqlplus / as sysasm

SQL> show parameter asm_diskstring

NAME TYPE VALUE

SQL> alter system set asm_diskstring = '/dev/asm*';

再次创建VOTEDISK，成功。

[root@rac1 init]# crsctl replace votedisk +SYSTEMDG

Successful addition of voting disk 8ebb7a63accb4fa8bfa7ab65df7a8c8a.

CRS-4266: Voting file(s) successfully replaced

(8) OCR和VOTEDISK都恢复完成后，重启CRS到正常模式。

[root@rac1 ~]#

4.2 修改CRS注册表中相关配置信息

(1) 挂载新的ASM磁盘组

[grid@rac1 ~]$ sqlplus / as sysasm

SQL> select name,state from v$asm_diskgroup;

NAME STATE

SYSTEMDG MOUNTED

ARCLOGDG DISMOUNTED

DATADG DISMOUNTED

SQL> alter diskgroup ARCLOGDG,DATADG mount;

(2) 更改CRS配置文件中数据库的磁盘组为DATADG和ARCLOGDG

[root@rac1 ~]# srvctl modify database -d csdb -a "DATADG,ARCLOGDG"

(3) 禁用并删除原来的磁盘组DATA

[root@rac1 ~]# srvctl disable diskgroup -g DATA

[root@rac1 ~]# srvctl remove diskgroup -g DATA

[root@rac1 rac-cluster]# crs_stat -t -v

(4) 在OCR注册表中修改Oracle数据库参数文件的位置

[root@rac1 ~]# 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

[root@rac1 ~]# su - oracle

[oracle@rac1 ~]$

[oracle@rac1 ~]$ cd /u01/app/oracle/backup

[oracle@rac1 backup]$ ll

total 221796

-rw-r----- 1 oracle asmadmin 5357568 Jul 5 15:19 arc_819991156_9.bk

-rw-r----- 1 oracle asmadmin 98304 Jul 5 15:19 spfile_0doe04js_1_1_20130705

[oracle@rac1 backup]$

(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

[oracle@rac1 ~]$ touch /u01/app/oracle/backup/init.ora

[oracle@rac1 ~]$ 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

[oracle@rac1 ~]$ sqlplus / as sysdba

SQL> startup nomount pfile='/u01/app/oracle/backup/init.ora';

ORACLE instance started.

Total System Global Area 238034944 bytes

(4) 使用RMAN恢复SPFILE到ASM磁盘组DATADG

[oracle@rac1 ~]$ rman target /

Finished restore at 06-JUL-13

(5) 使用恢复后spfile启动数据库，并修改control_files，db_recovery_file_dest，log_archive_dest等存在旧路径的参数值。

[oracle@rac1 ~]$ vi $ORACLE_HOME/dbs/initcsdb1.ora

SPFILE='+DATADG/csdb/spfilecsdb.ora'

Redo Buffers 7118848 bytes

(6) 查看数据库的DBID

[oracle@rac1 ~]$ strings /u01/app/oracle/backup/CSDB_819991120_5.bk | grep MAXVALUE,

返回的值类似下面的例子，其中那一窜数字即为DBID。

...

MAXVALUE, MAXVALUE!

3042905279, MAXVALUE,

3042905279, MAXVALUE,

...

(7) 恢复控制文件到新的ASM磁盘组DATADG

[oracle@rac1 ~]$ rman target /

RMAN> set dbid=3042905279

executing command: SET DBID

RMAN> restore controlfile from '/u01/app/oracle/backup/ctl_file_0coe04jq_1_1_20130705.ctl';

(8) 进入SQLPLUS，查看旧数据文件信息

[oracle@rac1 ~]$ sqlplus / as sysdba

SQL> alter database mount;

SQL> col name format a50

SQL> select file#,name from v$datafile;

FILE# NAME

     5 +DATA/csdb/datafile/users.265.819979913

(9) 使用RMAN恢复数据库

RMAN> run{
