各位好：
我现在想在 RHEL5 OS环境下的 11.2.0.1.0 的双节点RAC环境到单实例(也是11.2.0.1.0，单实例备库也使用ASM磁盘组）的DataGuard，但在主库执行：
rman target / auxiliary sys@stdb
RMAN > duplicate target database for standby nofilenamecheck;
后，提示如下错误：
Recovery Manager: Release 11.2.0.1.0 - Production on Thu Dec 18 23:44:01 2014

ORA-17502: ksfdcre:5 Failed to create file +DATA/stdb/controlfile/control01.ctl
ORA-15081: failed to submit an I/O operation to a disk
并且在备库RMAN中执行 restore standby controlfile from '/backup/rman_bak/dg_bak/racdb_ctl_0apqgkc8_1_1_20141218';
也是提示和以上一样的错误。并且我预先在+DATA磁盘组中创建stdb/controlfile目录也不行。
但我在备库的init参数文件中定义contro_files='/backup/control01.ctl' (OS目录）恢复就可以，但为什么恢复到ASM磁盘组就报以上错误呢？
并且我单实例的所有磁盘组已经是online正常了的：
[grid@dg-st tmp]$ crs_stat -t -v

请问为什么恢复到磁盘组就有问题，恢复到OS目录就可以。。。
还望各位帮忙解决一下，万分感谢！ |
