---------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"

---------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
