转://Oracle 11gR2 RAC ASM磁盘全部丢失后的恢复
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-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.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

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

Device/File integrity check succeeded

Logical corruption check succeeded
(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

再次创建VOTEDISK，成功。
[root@rac1 init]# crsctl replace votedisk +SYSTEMDG
Successful addition of voting disk 8ebb7a63accb4fa8bfa7ab65df7a8c8a.
Successfully replaced voting disk group with +SYSTEMDG.
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 2560 Jul 5 15:19 arc_819991158_11.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

Variable Size 180356160 bytes
Database Buffers 50331648 bytes
Redo Buffers 5120000 bytes
SQL>
(4) 使用RMAN恢复SPFILE到ASM磁盘组DATADG
[oracle@rac1 ~]$ rman target /
Recovery Manager: Release 11.2.0.3.0 - Production on Sat Jul 6 13:59:26 2013
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.

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';

Finished restore at 06-JUL-13
(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

4 +DATA/csdb/datafile/undotbs2.264.819979905
5 +DATA/csdb/datafile/users.265.819979913
(9) 使用RMAN恢复数据库
RMAN> run{

3> set newname for datafile 2 to '+DATADG/csdb/datafile/sysaux.261.819979871';

4.4 完成恢复操作
(1) 在其他RAC节点上更改OCR路径
[root@rac2 ~]# vi /etc/oracle/ocr.loc
ocrconfig_loc=+SYSTEMDG
local_only=FALSE
(2) 在恢复节点上重启CRS
[root@rac1 ~]# crsctl stop crs
[root@rac1 ~]# crsctl start has
(3) 在其他节点上启动CRS
[root@rac2 ~]# crsctl start crs
