11gR2 OCR&VOTEDISK 從ASM向裸裝置遷移(EXPIMP方式)

ASM
ASM上的OCR是200多M的，而客戶劃的OCR是128M，直接replace會報告裝置太小，於是只好測試下最後一種辦法，EXP/IMP。發現完全可以，步驟如下

[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


記錄下遇到的問題

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]

新增的裝置檔案比原檔案小，一般建議OCR,VOTEDISK都不要小於280M可用空間
解決辦法用使用EXP/IMP遷移。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

檔案系統上，不允許OCR的副本在同一個目錄
新建一個目錄放就OK


3.CRS-4602 & Failure 27
替換OCR前，替換VOTEDISK報該錯誤
[root@database1 ~]# crsctl replace votedisk /dev/raw/raw1 /dev/raw/raw2 /dev/raw/raw3 /dev/raw/raw4 /dev/raw/raw5

CRS-4000: Command Replace failed, or completed with errors.

遷移完OCR後，在遷移VOTEDISK就沒有該問題

4.repair
OCR的位置在/etc/oracle/ocr.loc中指定
repair的作用是強制修改該配置檔案。該命令需要在-excl -nocrs的環境中使用
修改後可以在考慮restore/imp等動作
