检查OCR盘信息：

[root@s2-11g grid]# ocrcheck -config

Oracle Cluster Registry configuration is :

Device/File Name : +OCRVOT

[root@s2-11g grid]# more /etc/oracle/ocr.loc

ocrconfig_loc=+OCRVOT

local_only=FALSE

新添加替换的OCR磁盘组：

[root@s2-11g grid]# ocrconfig -add +NOCRVOTE

检查添加的磁盘组：

[root@s2-11g grid]# ocrcheck -config

[root@s2-11g grid]# [root@s2-11g grid]# [root@s2-11g grid]# more /etc/oracle/ocr.loc

#Device/file getting replaced by device

+NOCRVOTE ocrconfig_loc=+OCRVOT

ocrmirrorconfig_loc=+NOCRVOTE

删除原先磁盘组：

[root@s2-11g grid]# ocrconfig -delete +OCRVOT

[root@s2-11g grid]# more /etc/oracle/ocr.loc

至此，OCR磁盘组替换完毕

以下自己添加...但测试通过

以下是votedisk位置改变：

GRID:>crsctl replace votedisk +OCR_VOTE2

以上修改完毕后还在再修改asm spfile的存储位置：

创建pfile :

create pfile='/u01/app/orace/initasm.ora' from spfile;

关闭asm

srvctl stop asm -o force -f

以pfile启动asm实例

startup pfile='/u01/app/orace/initasm.ora' ;

创建spfile到新磁盘组

create spfile='+OCR_VOTE2' FROM PFILE;

最后再停止asm实例并以默认spfile启动 看能否成功，注意每个节点都要启动。
