DELL R710服务器内存故障排错

dmidecode - DMI table decoder

通过dmidecode可以得知，有点像windows下的资源管理器

man dmidecode 可以得到详细的介绍和使用方法，dmidecode - DMI table decoder，DMI (Desktop Management Interface, DMI)，其他不过多赘述。

可以在linux下获取有关硬件方面的信息输出的信息包括 BIOS、系统、主板、处理器、内存、缓存等，rhel5版本自动安装了这软件

今天查看内存突然发现内存大小少了8G(本来应该是8个8G的),要是以前我会找DELL工程师来检查时那根坏了，再更换之，DELL工程师一般是重启服务器再BIOS自检时找出那一条坏了。如今用dmidecode 同样可以找出

过程如下：

# free -g

# dmidecode -t memory

# dmidecode 2.7

SMBIOS 2.6 present.

从上面信息可以看到，服务器总共有A1-A9，B1-B9 18个通道，其中A1-A8上插了内存条，据我所知，服务器内存条是三通道，这种插发并不是DELL推荐插法，

这个后续我会提供DELL服务器内存插法图，其中A6上面看不到内存信息，而其他的有 Size: 8192 MB,Speed: 1333 MHz (0.8 ns),所以A6这个插槽上内存体

坏了。

R710内存插法: X-表示安装内存, NA表示不安装内存.
