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 #

[root@localhost ~]# cat set_idrac_ip.sh
    
    #!/usr/bin/env bash
    
    # @Author         : Eric Winn

    # @File           : set_idrac_ip
    
    # @Software       : PyCharm
    
    # the file of idrac
    
    idrac_ip_list_file=${1}
    
    if [ ! -f "${idrac_ip_list_file}" ]; then
    
        echo "idrac_ip_list_file is not found!!!!"
    
        echo "$0 [idrac_ip_list_file]"
    
        exit 127
    
    fi
    
    # idrac Default infomation
    
    idrac_default_ip=${2:-192.168.0.120}
