ORA-15031: disk specification '/dev/oracleasm/disks/*' matches no disks

执行asmca创建磁盘组没有问题，但以sqlplus / as sysasm登陆创建却出现异常

SQL>create diskgroup DATA external redundancy disk '/dev/oracleasm/disks/*'

*
ERROR at line 1:
ORA-15018: diskgroup cannot be created

ORA-15031: disk specification '/dev/oracleasm/disks/*' matches no disks

解决方法

SQL> show parameter asm_diskstring;
