是采用crs online的状态来替换ocr主文件的，这篇我们写的是在crs offline的状态下如何替换ocr主文件

命令如下：

./ocrconfig -repair ocr /dev/rhdisk8

./ocrconfig -overwrite

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     130852

Used space (kbytes)      :       4636

Available space (kbytes) :     126216

ID                       : 1542042236

Device/File Name         : /dev/rhdisk11

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

原来是hdisk11,替换成hdisk8

1.赋予hdisk8 相关 权限(假设hdisk8已经从存储上划分lun出来)

chown root:oinstall /dev/rhdisk8

chmod 640 /dev/rhdisk8

2.两边节点停止crs

crs stop crs

3.用ocrconfig -repair ocr命令来替换

[root@p520:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -repair ocr /dev/rhdisk8

[root@p520:/crs/app/oracle/product/crs_1/bin]#./ocrcheck

PROT-601: Failed to initialize ocrcheck

[root@p520:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -overwrite

PROT-1: Failed to initialize ocrconfig

报PROT-1: Failed to initialize ocrconfig错误,这时我们还需要对ocr盘做个restore

./ocrconfig -showbackup

[root@p650:/crs/app/oracle/product/crs_1/cdata/crs]#ls -ltr

total 54424

-rw-r--r--    1 root     system      3477504 May 26 13:59 week.ocr

-rw-r--r--    1 root     system      4861952 May 27 14:09 backup02.ocr

-rw-r--r--    1 root     system      4878336 May 28 14:48 backup01.ocr

-rw-r--r--    1 root     system      4882432 Jun 02 17:15 backup00.ocr

-rw-r--r--    1 root     system      4882432 Jun 02 17:15 day.ocr

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrconfig -restore /crs/app/oracle/product/crs_1/cdata/crs/week_.ocr

[root@p650:/crs/app/oracle/product/crs_1/bin]#./ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     130852

Used space (kbytes)      :       4636

Available space (kbytes) :     126216

ID                       : 1542042236

Device/File Name         : /dev/rhdisk8

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

已经替换过来,这时我们查

[root@p650:/crs/app/oracle/product/crs_1/log/p650/client]#more  ocrconfig_827524.log

日志记录有Exiting [status=success]... 的记录

4.启动crs

crsctl start crs

crs能正常启动,替换成功。
