No Reboot Required: Configuring Dell iDRAC via RACADM

Posted on October 16, 2015 Updated on March 21, 2026

Configuring the Integrated Dell Remote Access Controller (iDRAC) is usually a “Day 1” task performed in the BIOS. But what if you’ve already deployed the server and realized the NIC isn’t configured, or the IP needs to change?

By using the Dell RACADM (Remote Access Controller Admin) utility, you can modify network settings, reset credentials, and pull system health logs directly from the command line without a single second of downtime.

Getting the Tools

To start, download the Dell EMC OpenManage DRAC Tools. This package includes the RACADM executable. You can install this on the local server or on your management workstation to manage servers over the network.

1. Remote RACADM (From your Workstation)

If you have the current credentials but need to change settings remotely, use the -r (remote), -u (user), and -p (password) flags.

Example: Get System Information

Bash

racadm -r 10.1.1.1 -u root -p calvin getsysinfo

Note: If you get an SSL certificate error, the command will still run. To force the command to stop on certificate errors for security, add the -S flag.

2. Local RACADM (From the Server OS)

If you are logged into the Windows or Linux OS on the Dell server itself, you don’t need credentials. The tool communicates directly with the hardware via the IPMI driver.

Example: Quick Network Setup

Bash

# Check current config
racadm getniccfg
# Set a new Static IP, Subnet, and Gateway
racadm setniccfg -s 192.168.1.50 255.255.255.0 192.168.1.1

3. Deep Configuration (The Config Group Method)

For more granular control (like setting DNS servers or the DRAC name), you can target specific configuration groups.

The “Lazy Admin” DNS Setup Script:

Bash

racadm config -g cfgLanNetworking -o cfgNicIpAddress 172.17.2.124
racadm config -g cfgLanNetworking -o cfgNicNetmask 255.255.252.0
racadm config -g cfgLanNetworking -o cfgDNSServer1 172.17.0.6
racadm config -g cfgLanNetworking -o cfgDNSRacName MyServer-iDRAC
racadm config -g cfgLanNetworking -o cfgDNSDomainName corp.company.com

4. SSH / Serial RACADM

If you are already connected to the iDRAC via SSH, you don’t need to repeat the racadm command prefix. Simply type racadm and hit enter to enter the RACADM shell:

Bash

admin@idrac-web-01: racadm
racadm>> getsysinfo
racadm>> serveraction powercycle

Why this is a “Lazy Admin” Win

Instead of walking to the cold aisle with a crash cart or waiting for a 20-minute reboot cycle, you can script the iDRAC configuration of an entire rack in seconds.
