批量自动化配置Dell服务器idrac管理口IP

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。只要运行起这个，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  | 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

[root@localhost ~]# cat set_idrac_ip.sh

#!/usr/bin/env bash

if [ ! -f "${idrac_ip_list_file}" ]; then

    echo "idrac_ip_list_file is not found!!!!"

    echo "$0 [idrac_ip_list_file]"

    exit 127
