【iDRAC】突破错误信息壁垒，利用iDRAC提高效率

序

面对旧服务器上的黄色警示灯，工作人员往往陷入困惑。更糟糕的是，如果该服务器转手多次，缺少root用户密码和IP地址，那么要访问服务器iDRAC就更困难了。但是出现问题的硬件蕴含着重要信息，为了解开这个谜团，我们需要掌握iDRAC的知识，并学习升级iDRAC固件和使用RACADM自定义iDRAC基本设置的技巧。

升级iDRAC固件和自定义基本设置带来了显著的好处，其中包括解决潜在的安全漏洞和故障问题，提高服务器的稳定性和安全性。同时，定制化iDRAC的基本设置可以为我们提供远程访问服务器的便利性，无需前往机房或现场进行实际操作。最重要的是，可以准确地诊断和解决服务器上的问题，最大程度地提高工作效率和服务器的整体性能。

接下来我们将分享具体的步骤和技巧，让您了解如何升级iDRAC固件和安装RACADM并通过其来自定义iDRAC基本设置。这份指南将帮助您解密旧服务器的秘密，挖掘潜藏在其中的无限潜力！

Part A： 通过Linux命令行更新iDRAC版本

在Dell官网找到服务器的最新iDRAC固件并下载，然后上传到对应服务器中。

服务器型号：DELL PowerEdge R720xd
iDRAC版本号：v.2.65.65.65（下载地址）
服务系统信息：Debian 11

root@www:~# chmod +x iDRAC-with-Lifecycle-Controller_Firmware_0GHF4_LN_2.65.65.65_A00.BIN
root@www:~# ./iDRAC-with-Lifecycle-Controller_Firmware_0GHF4_LN_2.65.65.65_A00.BIN

Part B：安装iDrac - RACADM

1. 安装需要的软件

root@www:~# apt install gpg libssl-dev libargtable2-0 -y
1

2. 将存储库密钥添加到apt中

root@www:~# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys  1285491434D8786F
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
Executing: /tmp/apt-key-gpghome.bSkoZ9PFZ9/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 1285491434D8786F

gpg: Total number processed: 1
gpg:               imported: 1

3. 添加sources.list

root@www:~# echo 'deb http://linux.dell.com/repo/community/openmanage/932/bionic bionic main' | tee -a /etc/apt/sources.list.d/linux.dell.com.sources.list
deb http://linux.dell.com/repo/community/openmanage/932/bionic bionic main

4. 通过输入以下命令，让apt知道新的软件存储库：

root@www:~# apt update
1

5. 使用 apt 命令安装 iDrac RACADM 软件。

root@www:~# apt install srvadmin-idracadm7 -y

6. 为了方便起见，我们将在/usr/local/bin中创建一个racadm的别名，这样可以在任何用户下简单地通过racadm命令调用。

root@www:~# ln -s /opt/dell/srvadmin/bin/idracadm7 /usr/local/bin/racadm

7. 现在您可以在shell（Linux命令提示符）中直接输入racadm，并将会呈现racadm帮助页面：racadm。
