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
CSV文件
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：
|
1 2 3 |
[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 |

注：后面的idrac_ip是csv文件名

我看不懂脚本，请问服务器原来的iDRAC有IP地址吗？？？你这个脚本是跑在服务器的操作系统下面的？还是笔记本的操作系统下，然后用笔记本一台台的接iDRAC的接口？
Dell 服务器管理口默认的地址是192.168.0.120，可以在笔记本上安装个CentOS的虚拟机网卡桥接，然后运行这个脚本，根据提示一台台的接到服务器的IDRAC口上就行了
