RAC如何在共享磁盘中创建文件夹

RAC11gR2设置控制文件RMAN备份，备份到asm管理的data磁盘的ctrlbak/下，结果报错

ORA-01580: error creating control backup file +DATA/<span><span>ctrlbak</span></span>/snapcf_orcl.fORA-17502: ksfdcre:4 Failed to create file +DATA/<span><span>ctrlbak</span></span>/snapcf_orcl.fORA-15173: entry '<span><span>ctrlbak</span></span>' does not exist in directory '/'

当时有点蒙，共享磁盘不自己常见路径的么？这咋搞？后来想起来asm磁盘管理工具asmcmd了

[grid@lmrac1 ~]$ asmcmdASMCMD> lsDATA/FRA/OCR/ASMCMD> cd DATAASMCMD> lsORCL/ASMCMD> mkdir ctrlbakASMCMD> lsORCL/ctrlbak/ASMCMD> 

搞定！
