oralce 11g rac ocr和votedisk遷移

1、新建一個磁盤組+NEW
Create diskgroup CRS NORMAL REDUNDANCY
FAILGROUP CRS_0000 disk '/dev/asm-orctest1'
FAILGROUP CRS_0001 disk '/dev/asm-orctest2'
FAILGROUP CRS_0002 disk '/dev/asm-orctest3'
ATTRIBUTE 'compatible.asm' = '11.2';

2、查看ocr備份
[root@rac02 bin]# ./ocrconfig -manualbackup

ocrconfig -showbackup
[root@rac02 bin]# ./ocrconfig -showbackup manual
rac01     2017/08/03 06:47:10     /u01/11.2.0/grid/cdata/rac-cluster/backup_20170803_064710.ocr
rac02     2017/08/01 02:32:01     /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

2、2個節點停止集群并修改配置文件（更改里面的磁盤組名字為新建的磁盤組）
./crsctl stop crs

vi /etc/oracle/ocr.loc

3、啟動一個節點到獨占模式并確認磁盤組+NEW是否mount，如沒有，手動mount。

crsctl start crs -excl -nocrs

SQL> select  GROUP_NUMBER, NAME,STATE from  v$asm_diskgroup;

GROUP_NUMBER NAME                           STATE
------------ ------------------------------ -----------
           1 ASM_DATA1                      MOUNTED
           2 ASM_FL                         MOUNTED
           3 CRS                            MOUNTED
           4 DATA                           MOUNTED

4、使用OCR備份恢復OCR到新的磁盤組（注意提前更改ocr.loc）
#./ocrconfig -restore  /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

[root@rac02 bin]# ./ocrconfig -manualbackup
rac01     2017/08/03 06:47:10     /u01/11.2.0/grid/cdata/rac-cluster/backup_20170803_064710.ocr
rac02     2017/08/01 02:32:01     /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr

5、恢復votedisk
[root@rac02 bin]# ./crsctl replace votedisk  +CRS
[root@rac02 bin]# ./ocrconfig -restore  /u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr
[root@rac02 bin]# ./crsctl replace votedisk  +CRS
Successful addition of voting disk 99fc4fb627ab4ffabfa4819288ef362d.
Successful addition of voting disk 69c39aef708f4f0abf39c97b4c55dcea.
Successful addition of voting disk 6bef23769bae4f5fbfb594f99707b160.
Successful deletion of voting disk 264b8b526ac54fe9bf80c5eee1350526.
Successfully replaced voting disk group with +CRS.
CRS-4266: Voting file(s) successfully replaced

檢查
ocrcheck---------------------------------------------檢查結果未變化
crsctl query css votedisk
[root@rac02 bin]# ./ocrcheck

Located 3 voting disk(s).

6、刪除掉原來
./ocrconfig -delete  +DATA

然后重啟集群
