原因：udev绑定问题

解决方法：

修改asm参数：asm_diskstring
sqlplus / as sysasm
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
asm_diskstring                       string      /dev/asm*, AFD:*

alter system set asm_diskstring = '/dev/asmdisk/*';
