CRS常用OCR和Votedisk的操作命令总结

查看votedisk的存储信息
crsctl query css votedisk
[oracle@inth-rac01 ~]$ /opt/crs/product/10.2.0.1/crs_1/bin/crsctl query css votedisk
0. 0 /dev/raw/raw1
备份votedisk: dd if=/dev/raw/votediskcopied of=/dev/raw/raw1
恢复votedisk: dd if=/dev/raw/raw1 of=/dev/raw/votediskcopied

ocrcheck

导出导入
可以用raw的命令来备份和恢复，不过ocrconfig提供了专门的命令来导出和导入还提供了镜像的方法

OCR手动导出:ocrconfig -export /tmp/ocr_bak
OCR手动导入:ocrconfig -import /tmp/ocr_bak
恢复OCR ocrconfig -restore /opt/product/10.2.0.1/crs/cdata/crs/backup01.ocr
添加OCR镜像盘:

创建用于镜像OCR的RAW设备,比如为:/dev/raw/ocrcopied
用ocrconfig –export 导出OCR的信息
编辑/etc/oracle/ocr.loc文件,添加ocrmirrorconfig_loc行
$ cat ocr.loc
ocrconfig_loc=/dev/raw/raw2
ocrmirrorconfig_loc=/dev/raw/ocrcopied
local_only=FALSE
用ocrconfig –import 导入OCR的信息
检查ocr设置信息
$ ocrcheck
