如何迁移OCR和votingdisk到其他asm磁盘组？针对这个问题，今天小编总结这篇有关OCR和votingdisk的文章，希望能帮助更多想解决这个问题的朋友找到更加简单易行的办法。

1.查看ocr和votedisk
[oracle:/home/oracle:RACTEST1] ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3104
Available space (kbytes) : 259016
ID : 44728649
Device/File Name : +OCR1
Device/File integrity check succeeded

                                Device/File not configured

                                Device/File not configured

                                Device/File not configured

                                Device/File not configured

     Cluster registry integrity check succeeded

     Logical corruption check bypassed due to non-privileged user

[oracle:/home/oracle:RACTEST1] crsctl query css votedisk
*## STATE File Universal Id File Name Disk group

ONLINE a5ef8885d1564f99bf0e0d77286c3b1f (/dev/oracleasm/disks/OCR11) [OCR1]
Located 1 voting disk(s).

SQL> select GROUP_NUMBER,NAME,SECTOR_SIZE,ALLOCATION_UNIT_SIZE,STATE,TYPE,VOTING_FILES from v$asm_diskgroup;

GROUP_NUMBER NAME SECTOR_SIZE ALLOCATION_UNIT_SIZE STATE TYPE VOT

       1 DATA               512              1048576 MOUNTED    EXTERN     N
       2 OCR1               512              1048576 MOUNTED    EXTERN     Y

2.创建新的ASM diskgroup（asmca图形界面创建）
create diskgroup OCR normal redundancy disk '/dev/oracleasm/disks/OCR01','/dev/oracleasm/disks/OCR02','/dev/oracleasm/disks/OCR03' attribute 'compatible.asm'='11.2';

SQL> select GROUP_NUMBER,NAME,SECTOR_SIZE,ALLOCATION_UNIT_SIZE,STATE,TYPE,VOTING_FILES from v$asm_diskgroup;

GROUP_NUMBER NAME SECTOR_SIZE ALLOCATION_UNIT_SIZE STATE TYPE VOT

       1 DATA               512              1048576 MOUNTED    EXTERN     N
       2 OCR1               512              1048576 MOUNTED    EXTERN     Y
       3 OCR                512              1048576 MOUNTED    NORMAL     N

3.votedisk从+OCR1 更改到 +OCR
[oracle:/home/oracle:RACTEST1] crsctl replace votedisk +OCR
Successful addition of voting disk 9b4ac868901f4f89bf191e59baa3442b.
Successful addition of voting disk 2c2eff1ca2ad4f7bbfcdf8fc913dcc45.
Successful addition of voting disk 652d503ff1154fd6bfdfe3273a12d529.
Successful deletion of voting disk a5ef8885d1564f99bf0e0d77286c3b1f.
Successfully replaced voting disk group with +OCR.
CRS-4266: Voting file(s) successfully replaced
[oracle:/home/oracle:RACTEST1] crsctl query css votedisk
*## STATE File Universal Id File Name Disk group

ONLINE 9b4ac868901f4f89bf191e59baa3442b (/dev/oracleasm/disks/OCR01) [OCR]
ONLINE 2c2eff1ca2ad4f7bbfcdf8fc913dcc45 (/dev/oracleasm/disks/OCR02) [OCR]
ONLINE 652d503ff1154fd6bfdfe3273a12d529 (/dev/oracleasm/disks/OCR03) [OCR]
Located 3 voting disk(s).

4.更改ocr
[root@ractest1 disks]# ocrconfig -add +OCR
[root@ractest1 disks]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3108
Available space (kbytes) : 259012
ID : 44728649
Device/File Name : +OCR1
Device/File integrity check succeeded
Device/File Name : +OCR
Device/File integrity check succeeded

                                Device/File not configured

                                Device/File not configured

                                Device/File not configured

     Cluster registry integrity check succeeded

     Logical corruption check succeeded

[root@ractest1 disks]# ocrconfig -delete +OCR1
[root@ractest1 disks]# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3108
Available space (kbytes) : 259012
ID : 44728649
Device/File Name : +OCR
Device/File integrity check succeeded

                                Device/File not configured

                                Device/File not configured

                                Device/File not configured

                                Device/File not configured

     Cluster registry integrity check succeeded

     Logical corruption check succeeded

5.查看asm参数文件存放的位置并修改到+OCR上
SQL> show parameter spfile

NAME TYPE VALUE

spfile string +OCR1/ractest-cluster/asmparam
eterfile/registry.253.10297677
13

SQL> create pfile='/oracle/app/product/grid/dbs/pfile_ASM1.ora' from spfile;

File created.

SQL> create spfile='+OCR' from pfile='/oracle/app/product/grid/dbs/pfile_ASM1.ora';

File created.

SQL> show parameter spfile

NAME TYPE VALUE

spfile string +OCR1/ractest-cluster/asmparam
eterfile/registry.253.10297677
13

6.一节点重启crs
[root@ractest1 disks]# crsctl stop crs
[root@ractest1 disks]# crsctl start crs
[root@ractest1 disks]# su - oracle
[oracle:/home/oracle:RACTEST1] srvctl start instance -d RACTEST -n ractest1

SQL> show parameter spfile

7.2节点重启crs
[root@ractest2 ~]# crsctl stop crs
[root@ractest2 ~]# crsctl start crs
[root@ractest2 ~]# su - oracle
[oracle:/home/oracle:RACTEST2] srvctl start instance -d RACTEST -n ractest2
SQL> show parameter spfile

8.删除 +OCR1

SQL> select GROUP_NUMBER,NAME,SECTOR_SIZE,ALLOCATION_UNIT_SIZE,STATE,TYPE,VOTING_FILES from v$asm_diskgroup;
GROUP_NUMBER NAME SECTOR_SIZE ALLOCATION_UNIT_SIZE STATE TYPE VOT

       1 DATA               512              1048576 MOUNTED                           EXTERN             N
       2 OCR1               512              1048576 MOUNTED                           EXTERN             N
       3 OCR                512              1048576 MOUNTED                           NORMAL             Y

SQL> drop diskgroup OCR1 including contents;
drop diskgroup OCR1 including contents
*
ERROR at line 1:

GROUP_NUMBER NAME SECTOR_SIZE ALLOCATION_UNIT_SIZE STATE TYPE VOT

       1 DATA               512              1048576 MOUNTED                           EXTERN             N

       3 OCR                512              1048576 MOUNTED                           NORMAL             Y

SQL> drop diskgroup OCR1 including contents;
drop diskgroup OCR1 including contents
*
ERROR at line 1:

SQL> alter diskgroup OCR1 mount;

Diskgroup altered.

SQL> drop diskgroup OCR1 including contents;

Diskgroup dropped.

SQL> select GROUP_NUMBER,NAME,SECTOR_SIZE,ALLOCATION_UNIT_SIZE,STATE,TYPE,VOTING_FILES from v$asm_diskgroup;

       1 DATA               512              1048576 MOUNTED                           EXTERN             N
       3 OCR                512              1048576 MOUNTED                           NORMAL             Y

2节点查看：
SQL> select GROUP_NUMBER,NAME,SECTOR_SIZE,ALLOCATION_UNIT_SIZE,STATE,TYPE,VOTING_FILES from v$asm_diskgroup;

GROUP_NUMBER NAME SECTOR_SIZE ALLOCATION_UNIT_SIZE STATE TYPE VOT

       1 DATA                                                                                               512              1048576 MOUNTED                           EXTERN             N
       3 OCR                                                                                                512              1048576 MOUNTED                           NORMAL             Y

9.最后在2个节点都查看一下
[oracle:/home/oracle:+ASM1] crsctl query css votedisk
