背景说明
工作中经常会遇到一次上几十台、几百台服务器的情况
每当到这个时候小伙伴们拿台笔记本和一根网线，一台服务器、一台服务器的去修改idrac IP
为了节约这个工作量，利用dell的racadm工具，写了下面这个脚本。只要运行起这个脚本，后面要做的就只是插拔网线的工作
安装racadm工具包
[root@localhost ~]# curl -s http://linux.dell.com/repo/hardware/dsu/bootstrap.cgi | bash [root@localhost ~]# yum -y install srvadmin-all
准备工作
在采购时dell会提供一份服务器的sn列表，会根据这个列表规划好每台服务器的idrac IP，我们可以将此转换成以逗号分隔的CSV文件如下：
[root@localhost ~]# cat idrac_ip_list AAAAAAA,10.10.10.2,255.255.255.0,10.10.10.1 BBBBBBB,10.10.10.3,255.255.255.0,10.10.10.1
脚本

运行
注：后面的idrac_ip是csv文件名
[root@localhost ~]# sh set_idrac_ip.sh idrac_ip Connecting ... Let's starting set sn ======> AAAAAAA Setting the new ip: 10.10.10.2 255.255.255.0 10.10.10.1 Static IP configuration enabled and modified successfully Now , Please change to a new server
