问题描述

节点关闭、无法启动、并显示以下事件：

Running full memory initialization. DIMM: XX mapped out. BIOS MRC mapped out DIMM. Major Code 0xED Minor Code 0x09 ERROR: [55] Memory not installed ERROR: DXE IPL not found

BIOS 升级失败，系统正在使用 BIOS 备份映像启动，除了“BIOS MRC mapped out DIMM “
（例如：升级前BIOS版本为18.7，升级后应该是18.13，但启动时却是18.5。）

如果在ONTAP升级期间遇到此问题描述、则ANDU可能会暂停、因为节点无法启动。
