问题描述

"BootDimmDisableAlert"报告了来自 system health alert show 的多个 DIMM

Node: node-01 Alert ID: BootDimmDisableAlert Resource: DIMM-10 Severity: Major Indication Time: XXX XXX XX XX:XX:XX XXXX Suppress: false Acknowledge: false Probable Cause: "DIMM-10" has been disabled to preserve memory interleaving. The system has booted with less memory. Possible Effect: System memory has been reduced, which can impact performance of the node. Corrective Actions: Repair failed or mapped-out DIMMs in the system. Then, reset the system to re-enable disabled DIMMs.

ECC 错误，其他 POST 内存错误和platform.reducedMemory事件可以在串行控制台日志中找到。
