注意当操作系统和存储之间出现IO错误时可能导致ORACLE ASM自动存储管理无法读取关键的ASM metadata,在下面的例子中 由于

ORA-27091: unable to queue I/O
ORA-27072: File I/O error
IBM AIX RISC System/6000 Error: 5: I/O error

IBM AIX 小机出现无法读取/dev/rhdiskdata4 裸设备上的数据块,导致ASM实例无法读取关键性的ASM FILE 1 文件指针信息,此时将无法读取其他asm源数据,虽然可能ASM diskgroup可以mount,但却无法读取任何diskgroup 中的文件,启动数据库也会报错。
