以上 ORA-15032、ORA-15075 ASM DISK PATH Problem就是由于LUN配置不当，导致LUN并非在RAC的多个节点上可见所导致的。

 

对于此类问题 首先确认已经合理设置了设备文件权限。

接着做如下操作来进一步确认：

 

 

 echo "======================" > fakedata.txt
date >> fakedata.txt
echo "======================" >> fakedata.txt

dd if=/home/oracle/test/fakedata.txt of=你要检验的设备名 bs=4096 count=1 conv=notrunc

之后使用od命令在多个节点上查看该设备上的内容即可确认在集群环境中该设备是否指向同一个LUN

 od -c 你要检验的设备名 | more
