迁移11g Rac中OCR和VOTEDISK

环境：OEL+oracle rac 11.2.0.3

迁移描述：将ocr和votedisk从+DATE上迁移到+OCR_VOTE上；

操作如下：

[root@ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     1469612
         Used space (kbytes)      :       3784
         Available space (kbytes) :     1465828
         ID                       :  1820175369
         Device/File Name         :      +DATA
                                    Device/File integrity check succeeded
                                    Device/File not configured
                                    Device/File not configured
         Cluster registry integrity check succeeded
         Logical corruption check bypassed due to non-privileged user

这里我们看到ocr放在+DATA中了

然后Add a new OCR device/file：

[root @ora2 ~]/u01/app/11.2.0/grid/bin/ocrconfig -add +OCR_VOTE
[root @ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheck
Status of Oracle Cluster Registry is as follows :
         Version                  :          3
         Total space (kbytes)     :     1469612
         Used space (kbytes)      :       3784
         Available space (kbytes) :     1465828
         ID                       :  1820175369
                                    Device/File integrity check succeeded
                                    +OCR_VOTE
                                    Device/File integrity check succeeded
                                    Device/File not configured
         Cluster registry integrity check succeeded
         Logical corruption check bypassed due to non-privileged user

（这时候ocr并不存在于+OCR_VOTE中）

迁移 ocr：
[root @ora2 ~]$/u01/app/11.2.0/grid/bin/ocrconfig -replace +DATA -replacement +OCR_VOTE

然后迁移votedisk：
[root @ora2 ~]$su - grid
[grid @ora2 ~]$crsctl replace votedisk +OCR_VOTE

查询一下votedisk的存放目录：
[grid @ora2 ~]$crsctl query css votedisk;

查询一下资源状态:
[grid @ora2 ~]$crsctl status resource -t

然后登录asm查看asmdisk的信息：

[sql] 
sqlplus / as sysasm  
SQL> select group_number,name,state,type from V$asm_diskgroup;  
SQL> select group_number,name,path from v$asm_disk;

使用show parameter spfile查看路径，如果存放在+DATA中，可以重建spfile：

如下操作：

[sql] 
SQL>create pfile='/u01/11.2.0/grid/dbs/asmpfile.ora' from spfile;  
SQL>create spfile='+OCR_VOTE' from pfile='/u01/11.2.0/grid/dbs/asmpfile.ora';

然后使用root用户重启crs即可

[root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl stop crs
[root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl start crs

然后再使用grid用户

[sql] 
su - grid  
SQL>alter diskgroup OCR_VOTE mount;

切换root用户

/u01/app/11.2.0/grid/bin/ocrconfig -delete +DATA

删除磁盘组+DATA：

[sql] 
SQL>alter diskgroup DATA dismount;  
SQL>drop diskgroup DATA including contents
