oralce11gracocr和votedisk遷移
1、新建一個(gè)磁盤(pán)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(gè)節(jié)點(diǎn)停止集群并修改配置文件（更改里面的磁盤(pán)組名字為新建的磁盤(pán)組）
./crsctl stop crs
vi /etc/oracle/ocr.loc
3、啟動(dòng)一個(gè)節(jié)點(diǎn)到獨(dú)占模式并確認(rèn)磁盤(pán)組+NEW是否mount，如沒(méi)有，手動(dòng)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(fù)OCR到新的磁盤(pán)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(fù)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(jié)果未變化
crsctl query css votedisk
[root@rac02 bin]# ./ocrcheck

6、刪除掉原來(lái)
./ocrconfig -delete +DATA
然后重啟集群
