AFF A400、A800、FAS8300、FAS8700：BIOS MRC 映射出 DIMM 消息
适用于
- AFF-A400、AFF-C400、ASA-A400、ASA-C400
- AFF-A800、AFF-C800、ASA-A800、ASA-C800
- FAS8300
- FAS8700
说明
- 在这些系统上，当遇到错误时，BIOS 可能会映射出内存 DIMM，例如：
DIMM: B0 mapped out. BIOS MRC mapped out DIMM. Major Code 0x30 Minor Code 0x13
- BIOS 消息使用两个字母的代码（
DIMM: B0）来标识出现错误的 DIMM。 - 会导致 DIMM 映射情况的 PANIC 消息示例：
PANIC: ECC error at DIMM-13: CE-04-1944-427DADF8,ADDR 0x15e4014780,(Node(1), Memory controller(0), CH(1), DIMM(0), Rank(0), Bank Group(0), Bank(0x0), Row(0x15c80), Col(0x318)) Uncorrectable Machine Check Error at CPU13. ...
