----查询OCR状态:
# /oracle/product/10g/crs/bin/ocrcheck            
PROT-601: Failed to initialize ocrcheck

 
---------替换原OCR磁盘,出错:
# /oracle/product/10g/crs/bin/ocrconfig -replace ocr '/dev/rdsk/c5t600A0B80005AD8BC0000020000000000d0s7'
/oracle/product/10g/crs/bin/ocrconfig -replace ocrmirror '/dev/rdsk/c5t600A0B80005AD8BC0000020000000001d0s7'
PROT-1: Failed to initialize ocrconfig


---------用repair选项替换原OCR磁盘:
# /oracle/product/10g/crs/bin/ocrconfig -repair ocr '/dev/rdsk/c5t600A0B80005AD8BC0000020000000000d0s7'
# /oracle/product/10g/crs/bin/ocrconfig -repair ocrmirror '/dev/rdsk/c5t600A0B80005AD8BC0000020000000001d0s7'

 
---------使用自动备份的ocr文件来恢复到新的OCR磁盘:
# /oracle/product/10g/crs/bin/ocrconfig -restore '/oracle/product/10g/crs/cdata/crs/backup00.ocr'


此处需注意新的磁盘容量要比原来的磁盘大,否则在恢复是会遇到错误PROT-22: Storage too small,这是
Oracle的一个Bug
