1停所有節點crs

crsctl stop crs

2備份OCR（導出方式）root用戶執行

ocrconfig -export /tmp/ocr.exp

3啟動crs并破壞OCR內容

crsctl start crs

dd if=/dev/zero f=/dev/raw/raw1 bs=1024 count=102400

4檢查OCR(ocrcheck,cluvfy)，此時crs已經自動關閉

[root@rac1 cluvfy]# ocrcheck

PROT-601: Failed to initialize ocrcheck

[root@rac1 cluvfy]# ./runcluvfy.sh comp ocr

5恢復OCR（導入方式）root用戶執行

ocrconfig -import /tmp/ocr.exp

6再次檢查OCR(ocrcheck,cluvfy)

[root@rac1 tmp]# ocrcheck
