Oracle Rac 11.2.0.3迁移OCR和VOTEDISK

环境:AIX7.1+Oracle Rac 11.2.0.3
迁移描述:今天在装Oracle Rac的时候,错误的将500G的数据盘用作OCRDG了,遂后续比较麻烦,只能讲ocr和votedisk迁移到新建的OCRDG上,并把DATADG删除并格式化该盘。(OCRDG为normal 冗余)
 
操作如下:

grid@rac1:/home/grid>/oraapp/grid/gridhome/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         :      +DATADG
                                    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
 
添加ocr信息到+OCRDG中:
root@rac1:./root>/oraapp/grid/gridhome/bin/ocrconfig -add +OCRDG

删除+DATADG中ocr:
root@rac1:./root>/oraapp/grid/gridhome/bin/ocrconfig -delete +DATADG

然后迁移votedisk:
grid@rac1:/home/grid>crsctl replace votedisk +OCRDG
 
查看votedisk的信息:
grid@rac1:/home/grid>crsctl query css votedisk;
 

查看diskgroup的信息:

sqlplus / as sysasm  
SQL> select group_number,name,state,type from V$asm_diskgroup;  

 
此时spfile存放在+DATADG中,需要重建spfile:

SQL>create pfile=‘/tmp/asmpfile.ora‘ from spfile;  
SQL>create spfile=‘+OCRDG‘ from pfile=‘/tmp/asmpfile.ora‘;
 

 
然后使用root用户重启crs即可(两边顺序重启)

root@rac1:./root>/oraapp/grid/gridhome/bin/crsctl stop crs
root@rac1:./root>/oraapp/grid/gridhome/bin/crsctl start crs

删除磁盘组+DATADG:

SQL>alter diskgroup DATADG dismount;  
SQL>drop diskgroup DATADG including contents;
