检查OCR盘信息： [root@s2-11g grid]# ocrcheck -config Oracle Cluster Registry configuration is : Device/File Name : +OCRVOT [root@s2-11g grid]# more /etc/oracle/ocr.loc ocrconfig_loc=+OCRVOT local_only=FALSE 新添加替换的OCR磁盘组： [root@s2-11g grid]# ocrconfig -add +NOCRVOTE
检查添加的磁盘组： [root@s2-11g grid]# ocrcheck -config Oracle Cluster Registry configuration is : Device/File Name : +OCRVOT Device/File Name : +NOCRVOTE [root@s2-11g grid]# [root@s2-11g grid]# [root@s2-11g grid]# more /etc/oracle/ocr.loc #Device/file getting replaced by device +NOCRVOTE ocrconfig_loc=+OCRVOT ocrmirrorconfig_loc=+NOCRVOTE local_only=false
删除原先磁盘组： [root@s2-11g grid]# ocrconfig -delete +OCRVOT [root@s2-11g grid]# more /etc/oracle/ocr.loc #Device/file +OCRVOT getting replaced by device +NOCRVOTE ocrconfig_loc=+NOCRVOTE local_only=false [root@s2-11g grid]# crs_stat -t Name Type Target State Host ———————————————————— ora.DATA.dg ora….up.type ONLINE ONLINE s1-11g ora….ER.lsnr ora….er.type ONLINE ONLINE s1-11g ora….N1.lsnr ora….er.type ONLINE ONLINE s2-11g ora….VOTE.dg ora….up.type ONLINE ONLINE s1-11g ora.OCRVOT.dg ora….up.type ONLINE ONLINE s1-11g ora.RECOVER.dg ora….up.type ONLINE ONLINE s1-11g ora.asm ora.asm.type ONLINE ONLINE s1-11g ora.cvu ora.cvu.type ONLINE ONLINE s2-11g ora.gsd ora.gsd.type OFFLINE OFFLINE ora.hzmc.db ora….se.type ONLINE ONLINE s1-11g ora….network ora….rk.type ONLINE ONLINE s1-11g ora.oc4j ora.oc4j.type ONLINE ONLINE s2-11g ora.ons ora.ons.type ONLINE ONLINE s1-11g ora….SM1.asm application ONLINE ONLINE s1-11g ora….1G.lsnr application ONLINE ONLINE s1-11g ora.s1-11g.gsd application OFFLINE OFFLINE ora.s1-11g.ons application ONLINE ONLINE s1-11g ora.s1-11g.vip ora….t1.type ONLINE ONLINE s1-11g ora….SM2.asm application ONLINE ONLINE s2-11g ora….1G.lsnr application ONLINE ONLINE s2-11g ora.s2-11g.gsd application OFFLINE OFFLINE ora.s2-11g.ons application ONLINE ONLINE s2-11g ora.s2-11g.vip ora….t1.type ONLINE ONLINE s2-11g ora.scan1.vip ora….ip.type ONLINE ONLINE s2-11g
至此，OCR磁盘组替换完毕
注：以上转载 http://blog.mchz.com.cn/?p=7981
以下自己添加...但测试通过
以下是votedisk位置改变：
GRID:>crsctl replace votedisk +OCR_VOTE2
以上修改完毕后还在再修改asm spfile的存储位置：
创建pfile :
create pfile='/u01/app/orace/initasm.ora' from spfile;
关闭asm
srvctl stop asm -o force -f
以pfile启动asm实例
startup pfile='/u01/app/orace/initasm.ora' ;
创建spfile到新磁盘组
create spfile='+OCR_VOTE2' FROM PFILE;
最后再停止asm实例并以默认spfile启动 看能否成功，注意每个节点都要启动。
