问题原因

asm盘绑盘时设定为grid:asmadmin,但是在创建oracle用户时没给asmadmin组。

解决办法

root用户更改属组
chgrp asmadmin /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

grid执行setasmgidwrap
setasmgidwrap o=/u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

ls -l /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
-rwxr-s--x. 1 oracle asmadmin 239626689 Jan 11 13:45 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle

在主库重新执行rman连接备库
顺利duplicate
