linux内存条排查

已发现2个内存错误，应用名称（kernel:）,日志内容(hangzhou-jishuan-DDS0248 kernel: sbridge: HANDLING MCE MEMORY ERROR hangzhou-jishuan-DDS0248 kernel: EDAC MC0: CE row 5, channel 0, label CPU_SrcID#0_Channel#3_DIMM#1:1 Unknown error(s): memory scrubbing on FATAL area : cpu=0 Err=0008:00c1 (ch=1), addr = 0x1c9bea000 = socket=0, Channel=3(mask=8), rank=5)

如何判断是第几条内存？

获取服务器内存信息（此信息可以在报修的时候提供给硬件厂商工程师，记得告诉他们仅供参考）。

shell命令：dmidecode | grep -A 9 -B 6 DIMM | grep Bank

Bank Locator: BRANCH 0 CHANNEL 1 DIMM 0

Bank Locator: BRANCH 0 CHANNEL 1 DIMM 1

Bank Locator: BRANCH 0 CHANNEL 2 DIMM 0

Bank Locator: BRANCH 0 CHANNEL 2 DIMM 1

Bank Locator: BRANCH 0 CHANNEL 3 DIMM 0

Bank Locator: BRANCH 0 CHANNEL 3 DIMM 1

Bank Locator: BRANCH 1 CHANNEL 1 DIMM 0

Bank Locator: BRANCH 1 CHANNEL 1 DIMM 1

Bank Locator: BRANCH 1 CHANNEL 2 DIMM 0

Bank Locator: BRANCH 1 CHANNEL 2 DIMM 1

Bank Locator: BRANCH 1 CHANNEL 3 DIMM 0

Bank Locator: BRANCH 1 CHANNEL 3 DIMM 1

内存顺序是从上向下1-12.根据报错信息CPU_SrcID#0_Channel#3_DIMM#1 : 得到CPU_SrcID 0，CHANNEL 3，DIMM 1。

可以判断为第六条条内存故障，也可以说第一颗cpu控制内存区域，CHANNEL为3，内存id为1。
