使用Shell脚本查詢服務器硬件信息

23213

1、为了方便查询服务器的硬件信息，将需要查询的内容整理成Shell脚步，输出自己想要的格式。其实就是通过dmidecode命令输出，然后通过sed，awk，cut命令的处理。
2、此脚步适用于HP DL系列的服务器，Dell PowerEdge系列的会有少许内容不同，所以在抓取过程会有小小报错。
3、脚步内容如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75

4、这里只对服务器厂商，内存，CPU配置和网卡信息，对于硬盘信息可根据不同厂商的管理工具来获取。HP使用hp-health-*rpm，G9版本以上使用hpssacli-*.rpm，安装以后使用：hpacucli ctrl all show config 查看RAID信息。Dell安装Dell OpenManage Server Administrator工具查看，通过命令：omreport storage pdisk controller=0来查看。
5、查看RAID信息还可以使用MegaCli开源工具进行查看，这里不作介绍。
