SLDIAG对与随机地址内存测试所替换的DIMM不同的DIMM返回错误状态

适用场景

支持SLDIAG的AFF和FAS型号

问题描述

• 在 更换DIMM期间、 对内存子系统执行操作步骤诊断：

*> sldiag device run -dev mem

• 完成SLDIAG测试时、"随机 地址内存测试"可能会显示错误状态：

*> sldiag device status

To see details use: sldiag device status -long
Device     TestName      StartDate       EndDate        Status    LOOP

There are still test(s) being processed.

• 进一步调查后、在与更换的DIMM不同的DIMM上发现可更正错误(CECC)：

*> sldiag device status -dev mem -long -state failed
