在配置Oracle ASM时可能会遇到错误，如ORA-15031、ORA-15025和ORA-27041。这些错误通常与磁盘指定不匹配、操作系统(I/O错误)或存储设备兼容性有关。在Solaris和AIX系统上，针对EMC存储的故障排查可能涉及到ASM_DISKSTRING设置、磁盘发现问题以及存储设备的bug。解决方案包括检查ASM配置、系统日志以及与硬件供应商联系获取支持。

ORA-15031 disk specification '/dev/rlvdisk1' matches no disks

有可能是ASM_DISKzSTRING没设

2.在Solaris上有可能是磁盘问题。

Asm Is not Discovering Disks On Solaris: ORA-15025 ORA-27041 SVR4 Error: 5: I/O error. (Doc ID 1300393.1)

SQL> create diskgroup testdg external redundancy disk '/dev/rdsk/c4t60060480000190103592533031453837d0s2';

3.在AIX上EMC存储可能有bug

SQL> show parameter asm_disk

NAME TYPE VALUE
------------------------------------ -----------
------------------------------
asm_diskgroups string
asm_diskstring string /dev/rhdiskpower10

SQL> select * from v$asm_disk;

no rows selected

SQL> create diskgroup test external redundancy disk '/dev/rhdiskpower10';
create diskgroup test external redundancy disk '/dev/rhdiskpower10'
