ASM上的OCR是200多M的，而客户划的OCR是128M，直接replace会报告设备太小，于是只好测试下最后一种办法，EXP/IMP。发现完全可以，步骤如下

[root@database1 ~]# ocrconfig -export /tmp/ocr.dmp
[root@database1 ~]# crsctl stop crs -f
[root@database2 ~]# crsctl stop crs -f
[root@database1 ~]# crsctl start crs -excl -nocrs
[root@database1 ~]# ocrconfig -repair -replace +CRSDG -replacement /dev/raw/raw1
[root@database1 ~]# ocrconfig -import /tmp/ocr.dmp
[root@database1 ~]# ocrcheck
[root@database1 ~]# crsctl stat res -t -init
[root@database1 ~]# crsctl stop crs -f
[root@database1 ~]# crsctl start crs
[root@database1 ~]# ocrconfig -add /dev/raw/raw2
[root@database1 ~]# ocrconfig -add /dev/raw/raw3
[root@database1 ~]# ocrcheck
[root@database1 ~]# crsctl replace votedisk /dev/raw/raw4
[root@database1 ~]# crsctl add css votedisk /dev/raw/raw5 /dev/raw/raw6
[root@database2 ~]# vi /etc/oracle/ocr.loc
ocrconfig_loc=/dev/raw/raw1
ocrmirrorconfig_loc=/dev/raw/raw2
ocrconfig_loc3=/dev/raw/raw3
[root@database2 ~]# crsctl start crs

记录下遇到的问题

1:Storage too small
root@abmdb01#[/]/oracle/app/11.2/grid/bin/ocrconfig -add /dev/vx/rdsk/ocrvote/lv_ocr_128m_02
PROT-22: Storage too small
PROC-31: Storage device for the cluster registry is too small Operating System error [No such device or address] [6]

添加的设备文件比原文件小，一般建议OCR,VOTEDISK都不要小于280M可用空间
解决办法用使用EXP/IMP迁移。ADD/DELETE/REPLACE均不行

2.PROT-36
root@abmdb01#[/]/oracle/app/11.2/grid/bin/ocrconfig -add /test/ocr2
PROT-36: Duplicate or previously used Oracle Cluster Registry location /test/ocr2 cannot be added

文件系统上，不允许OCR的副本在同一个目录
新建一个目录放就OK

3.CRS-4602 & Failure 27
替换OCR前，替换VOTEDISK报该错误
[root@database1 ~]# crsctl replace votedisk /dev/raw/raw1 /dev/raw/raw2 /dev/raw/raw3 /dev/raw/raw4 /dev/raw/raw5

迁移完OCR后，在迁移VOTEDISK就没有该问题

4.repair
OCR的位置在/etc/oracle/ocr.loc中指定
repair的作用是强制修改该配置文件。该命令需要在-excl -nocrs的环境中使用
修改后可以在考虑restore/imp等动作
