今天一大早朋友找到我说他们一个客户数据库更换存储后无法启动，发了一个报错给我。这个错误其实我也是第一次遇到，所以
这里简单记录一下。

分析响应的trace，可以看到响应的call stack信息：

从分析看是元数据方面同步出现了问题，后面从mos发现了一篇文档有简单描述：
SYMPTOMS
While mounting the ASM diskgroup with compatible.asm set to 12.1 or above .It was failing with below ORA-600,
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [7], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [1], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [3], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [4], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [1], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [3], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kfcInitPba15], [3], [4], [], [], [], [], [], [], [], [], []
With compatible.asm set to 12.1 or above , phys_meta_replicated attribute get enabled by default.
And copy complete allocation unit 0 of each asm disk within a diskgroup to allocation unit 11.
CAUSE
This issue most of the time observed due to IO completion failure allocation unit 11.
SOLUTION
Please open a SR and engage Oracle Support to review your issue and assist you.
该文档没有做过多描述。从分析来看Oracle 12c开始，对于盘头的数据备份在AU 11上，因此可能是au 0到au 11的镜像有问题。
我猜测可能是之前在实施replace 磁盘更换时有些问题。最后建议他们盘头前面数据dd清掉，然后重跑root.sh即解决了问题。
