asm如何更换ocr新磁盘组

测试如下，安装grid选择的四块100g的磁盘组命名为+DATA

创建了三块1g的用于ocr

 

创建磁盘组命令省略

切换root用户执行如下

[root@rac1 bin]# ./ocrconfig -add +OCR
PROT-30: The Oracle Cluster Registry location to be added is not usable
PROC-50: The Oracle Cluster Registry location to be added is inaccessible on nodes rac1.

root账户执行提示错误，asmcmd执行查看磁盘组没有mount ，于是进入slqplus 中对磁盘组进行上线处理

 

切换root继续执行

[root@rac1 bin]# ./ocrconfig -add +OCR
PROT-30: The Oracle Cluster Registry location to be added is not usable
PROC-8: Cannot perform cluster registry operation because one of the parameters is invalid.
ORA-15056: additional error message
ORA-17502: ksfdcre:4 Failed to create file +OCR.255.1
ORA-15221: ASM operation requires compatible.asm of 11.1.0.0.0 or higher
ORA-06512: at line 4

[root@rac1 bin]#

　　提示新的错误，DATA磁盘组时我安装grid时候创建的，OCR,ARCH 时安装后使用sql命令创建的

后来查资料时asm 兼容版本不一致，于是有下列操作步骤

 

[grid@rac1 ~]$ sqlplus / as sysasm
