oracle 10g RAC [恢复OCR]

----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
