我们经常让服务器中的DIMM因syslog中的以下错误而变坏：
May 7 09:15:31 nolcgi303 kernel: EDAC k8 MC0: general bus error: participating processor(local node response),time-out(no timeout) memory transaction type(generic read),mem or i/o(mem access),cache level(generic) May 7 09:15:31 nolcgi303 kernel: MC0: CE page 0xa0,offset 0x40,grain 8,syndrome 0xb50d,row 2,channel 0,label "": k8_edac May 7 09:15:31 nolcgi303 kernel: MC0: CE - no information available: k8_edac Error Overflow set May 7 09:15:31 nolcgi303 kernel: EDAC k8 MC0: extended error code: ECC chipkill x4 error
我们可以使用HP SmartStart CD来确定哪个DIMM有错误,但这需要使服务器停止生产.是否有一种巧妙的方法可以解决服务器运行时哪个DIMM出现故障？我们所有的服务器都是运行RHEL 5的HP硬件.
解决方法
除了使用EDAC代码之外,您还可以使用仅CLI的HP实用程序在机器联机时确定这一点. cli版本比基于Web的版本更轻量级,并且不需要您打开端口或让守护程序不断运行.
hpasmcli将为您提供故障模块的盒式磁带和模块.比分析EDAC快一点.
例：
hpasmcli -s "show dimm" DIMM Configuration ------------------ Cartridge #: 0 Module #: 1 Present: Yes Form Factor: 9h Memory Type: 13h Size: 1024 MB Speed: 667 MHz Status: Ok Cartridge #: 0 Module #: 2 Present: Yes Form Factor: 9h Memory Type: 13h Size: 1024 MB Speed: 667 MHz Status: Ok Cartridge #: 0 Module #: 3 Present: Yes Form Factor: 9h Memory Type: 13h Size: 1024 MB Speed: 667 MHz Status: Ok Cartridge #: 0 Module #: 4 Present: Yes Form Factor: 9h Memory Type: 13h Size: 1024 MB Speed: 667 MHz Status: Ok
失败的模块的状态将更改.
