The Integrated Dell Remote Access Controller (iDRAC) is a crucial component in managing Dell servers. It provides out-of-band management capabilities, allowing you to remotely monitor, manage, and update your server, even when the operating system is down. However, accessing the iDRAC requires a username and password. Forgetting or losing these credentials can be a significant hurdle. This guide provides a comprehensive exploration of methods to recover or reset your iDRAC credentials.
Understanding the Importance of iDRAC Credentials
The iDRAC acts as a gateway to your server’s core functions. Without the correct credentials, you’re locked out of vital management features. This includes remote power control, system health monitoring, firmware updates, and virtual media access. The iDRAC offers substantial control over your Dell server.
The significance of these credentials extends beyond basic functionality. In a data center environment, the iDRAC is essential for maintaining uptime, troubleshooting issues remotely, and performing essential maintenance tasks without physical access to the server.
Losing access can lead to significant downtime and increased operational costs, especially when remote management is essential. Therefore, it is crucial to either maintain a record of the credentials or to understand the recovery process.
Default iDRAC Credentials and Their Security Implications
By default, Dell iDRACs are shipped with a standard username and password. This is intended for initial setup. The default username is usually “root” and the default password is often “calvin”. However, it is crucial to understand that using these default credentials poses a significant security risk.
Leaving the default credentials unchanged exposes your server to potential unauthorized access. Malicious actors can easily exploit this vulnerability to gain control of your system, potentially leading to data breaches, system compromises, or denial-of-service attacks. Immediately changing the default iDRAC credentials after the initial setup is a critical security best practice.
If you suspect that your iDRAC is still using the default credentials, prioritize changing them immediately. Use strong, unique passwords. Utilize a combination of upper and lowercase letters, numbers, and symbols.
Methods for Recovering iDRAC Credentials
Several methods exist for recovering or resetting your iDRAC credentials. The appropriate method will depend on the specific iDRAC version, the configuration of your server, and your access to the physical server. We will explore the most common and effective techniques.
Method 1: Using RACADM (Remote Access Controller Admin)
RACADM is a command-line utility that allows you to manage iDRAC settings remotely or locally. It’s a powerful tool for both initial configuration and troubleshooting.
RACADM can be executed either locally on the server’s operating system (if accessible) or remotely via SSH if configured.
If you have access to the operating system, the local RACADM option is the easiest to use. Open a command prompt or terminal window. Execute RACADM commands to reset the iDRAC user password.
The exact commands may vary slightly depending on the iDRAC version. However, a common approach involves using the following RACADM command structure to reset the password for a specific user:
racadm set iDRAC.Users.[UserID].Password [NewPassword]
Replace [UserID] with the ID of the user you wish to reset the password for (usually 2 for the first user). Replace [NewPassword] with your desired new password.
For example, to reset the password for user ID 2 to “MyNewPassword123”, you would use the following command:
racadm set iDRAC.Users.2.Password MyNewPassword123
If you cannot access the operating system, you might be able to use remote RACADM via SSH. This requires that SSH access to the iDRAC has been previously enabled and configured. If you are not sure, this method will likely not work.
To connect to the iDRAC via SSH, use an SSH client like PuTTY. Enter the iDRAC’s IP address and port (usually port 22). Authenticate with the existing iDRAC credentials (if known).
After successfully connecting via SSH, you can use the same RACADM commands to reset the password as described for local RACADM.
Remember to apply the changes after executing the command. This is sometimes done automatically, but it can require a separate command depending on the iDRAC version. Check the iDRAC documentation for your specific model.
Method 2: Utilizing the iDRAC Web Interface
If you have access to the iDRAC web interface but have forgotten the password, you may be able to reset it through the interface, provided certain conditions are met.
This usually involves another administrator account that has the necessary privileges to modify user accounts. If you have another administrator account, log in using those credentials. Navigate to the user management section within the iDRAC web interface. This section typically allows you to modify or reset user passwords.
Locate the user account for which you want to reset the password. Select the option to reset the password. You will likely be prompted to enter a new password for the user. Choose a strong, unique password that meets your organization’s security requirements.
If there is no other available administrator account, this method will not work.
Method 3: Performing a Hardware Reset of the iDRAC
A hardware reset, also known as a cold reset, can sometimes restore the iDRAC to its factory default settings. This includes resetting the username and password to the default values. This is often a last resort as it also resets other iDRAC configurations.
Before performing a hardware reset, understand that you will lose all custom iDRAC configurations. This includes network settings, user accounts, and other customized settings. Document your existing configurations before proceeding.
The method for performing a hardware reset varies depending on the server model and iDRAC version. Consult the server’s documentation for the specific instructions. Often, this involves a small button on the server’s motherboard or back panel.
The button might be labeled “iDRAC Reset,” “System Identification Button,” or something similar. You might need a tool, such as a straightened paperclip, to press and hold the button.
Press and hold the button for the specified duration (usually around 15-30 seconds). Release the button and allow the iDRAC to reset. The iDRAC may take several minutes to reboot.
After the reset, try logging in with the default iDRAC credentials (“root” and “calvin”). If successful, immediately change the default password to a strong, unique password. Reconfigure your iDRAC network settings and other customizations.
Method 4: Using IPMI (Intelligent Platform Management Interface)
IPMI is a standardized hardware management interface that can be used to manage servers remotely. If IPMI is enabled on your server, you might be able to use it to reset the iDRAC password.
IPMItool is a command-line utility for managing IPMI-enabled devices. You can use IPMItool to reset the iDRAC password.
The exact commands will depend on your IPMItool version and the iDRAC implementation. However, a common approach involves using IPMItool to send a raw IPMI command to the iDRAC that resets the user password.
First, you need to identify the channel number for the iDRAC. This information is typically found in the server’s documentation or by using IPMItool to query the system. Then, use IPMItool to send a raw IPMI command to reset the user password on the identified channel. The syntax will resemble:
ipmitool raw [Channel Number] [Command Bytes]
The specifics of the Command Bytes will depend on the iDRAC version and the desired action. Consult the iDRAC documentation for the precise command sequence.
After executing the command, attempt to log into the iDRAC with the default credentials (or a previously known credential if the reset did not default to factory settings). Immediately change the password once logged in.
Method 5: Utilizing Dell EMC SupportAssist
Dell EMC SupportAssist is a suite of tools that can assist in managing and troubleshooting Dell servers. Depending on your SupportAssist configuration, it might offer features to help recover or reset iDRAC credentials.
Access the Dell EMC SupportAssist Enterprise console. Navigate to the server in question. Look for options related to remote management or iDRAC configuration.
SupportAssist might offer a password reset option that leverages its integration with the iDRAC. Follow the on-screen instructions to reset the password.
The functionality of SupportAssist depends on the subscription and configuration.
Best Practices for iDRAC Security and Password Management
To minimize the risk of losing access to your iDRAC and to enhance security, consider these best practices:
Change the default iDRAC credentials immediately after the initial setup. This is the most important step in securing your iDRAC.
Use strong, unique passwords for all iDRAC user accounts. A strong password should be at least 12 characters long and include a mix of upper and lowercase letters, numbers, and symbols.
Enable two-factor authentication (2FA) for iDRAC access. 2FA adds an extra layer of security by requiring a second verification factor, such as a code from a mobile app.
Regularly update the iDRAC firmware to the latest version. Firmware updates often include security patches that address known vulnerabilities.
Restrict iDRAC access to authorized personnel only. Limit the number of users who have access to the iDRAC and grant only the necessary privileges.
Implement network segmentation to isolate the iDRAC network from the rest of your network. This can help prevent unauthorized access to the iDRAC in the event of a network breach.
Monitor iDRAC logs for suspicious activity. Regularly review the iDRAC logs for any signs of unauthorized access attempts or other suspicious behavior.
Document your iDRAC credentials and store them in a secure location. If you need to recover your iDRAC credentials, having a record of them can save you time and effort. Consider using a password manager to securely store your credentials.
Consider using role-based access control (RBAC) to manage user permissions within the iDRAC. RBAC allows you to grant users specific privileges based on their roles, limiting their access to only the resources they need.
Disable unnecessary iDRAC services and features. Disabling unnecessary services can reduce the attack surface of the iDRAC.
Implement a password policy that requires users to change their iDRAC passwords regularly. This can help prevent compromised passwords from being used to gain unauthorized access.
Regularly audit your iDRAC security settings to ensure that they are configured correctly. This can help you identify and address any potential security vulnerabilities.
By following these best practices, you can significantly enhance the security of your iDRAC and protect your Dell servers from unauthorized access.

What is iDRAC and why is it important?
iDRAC, or Integrated Dell Remote Access Controller, is a management tool embedded within Dell PowerEdge servers. It provides out-of-band management capabilities, allowing administrators to remotely monitor, manage, and troubleshoot servers regardless of the operating system’s status or whether the server is even powered on. This includes tasks such as power cycling, system updates, and accessing the server’s console.
Its importance stems from its ability to drastically reduce downtime and improve operational efficiency. By enabling remote management, iDRAC allows for quicker problem resolution, reduces the need for physical server access, and streamlines server maintenance. This is particularly beneficial for organizations with geographically dispersed servers or limited on-site IT staff, as it ensures consistent and efficient server management from any location.
What are the common default iDRAC usernames and passwords?
Dell iDRAC units typically ship with a set of default credentials for initial access. While strongly discouraged for production environments, knowing these defaults is useful for first-time setup or troubleshooting a forgotten password. The most common default username is “root” and the default password is “calvin”. However, this can vary depending on the iDRAC version and server model.
Another frequently encountered default is username “root” with a blank password. It’s imperative to change these default credentials immediately after initial setup to secure your server. Leaving the default settings creates a significant security vulnerability, potentially allowing unauthorized access to your server and network. Refer to your server’s documentation for the specific default credentials if “root/calvin” doesn’t work.
How can I reset the iDRAC password using the Lifecycle Controller?
The Lifecycle Controller offers a method to reset the iDRAC password without needing the operating system to be functional. During the server’s boot process, you can access the Lifecycle Controller by pressing F10 when prompted. Navigate through the system setup options to find the iDRAC settings. Within those settings, there should be an option to reset the iDRAC password back to its default.
Keep in mind that resetting to the default password is a temporary measure and should be followed immediately by setting a strong, unique password. After resetting, access the iDRAC web interface or command-line interface to change the password to a secure one. Record the new password in a safe and accessible location for future reference. Ensuring physical access is required for Lifecycle Controller access is a security measure in itself.
What is the racadm command and how can I use it to reset the iDRAC password?
Racadm (Remote Access Controller Admin) is a command-line utility that allows administrators to manage Dell iDRAC remotely or locally from the operating system. It provides a wide range of functionalities, including the ability to reset the iDRAC password. To use racadm, you’ll need to have it installed on a system that can communicate with the iDRAC, either on the server itself or another networked machine.
The command to reset the password using racadm typically involves specifying the target iDRAC and providing the new password. A common command structure is `racadm -i rac -u
How do I reset the iDRAC to factory defaults if I’ve forgotten the username and password?
If you’ve completely lost both the username and password for your iDRAC, resetting it to factory defaults might be the only option. This will erase all custom configurations, including the network settings and user accounts, reverting the iDRAC to its original state. The method for performing a factory reset varies depending on the iDRAC version and server model but often involves a physical button press or a jumper setting on the server’s motherboard.
Consult your server’s hardware documentation for the specific instructions on how to perform a factory reset. Typically, the documentation will outline the location of the reset button or jumper and the procedure for activating it. Be extremely cautious during this process to avoid any accidental hardware damage. After the reset, you can access the iDRAC using the default credentials and then reconfigure it according to your needs, ensuring you create and securely store a new, strong password.
What are the security implications of using default iDRAC credentials?
Using the default iDRAC credentials poses a significant security risk to your server and network. Cybercriminals actively scan networks for devices using default credentials, making them easy targets for exploitation. Once an attacker gains access to the iDRAC, they can remotely control the server, install malware, steal sensitive data, or disrupt critical services.
The consequences can be severe, including data breaches, financial losses, and reputational damage. It is crucial to change the default iDRAC username and password immediately after the initial setup. Implement strong password policies, use unique passwords for each device, and regularly audit your iDRAC configurations to ensure ongoing security. Enable two-factor authentication, if available, for added protection.
What are some best practices for managing and securing iDRAC credentials?
To effectively manage and secure your iDRAC credentials, implement a robust password management strategy. This includes creating strong, unique passwords that meet complexity requirements (e.g., minimum length, mixed case, special characters). Avoid using easily guessable passwords or reusing passwords across multiple systems. Implement a system for securely storing and managing passwords, such as a password manager, for authorized personnel.
Regularly audit iDRAC user accounts and permissions to ensure only authorized individuals have access. Disable unnecessary accounts and review user activity logs for suspicious behavior. Consider implementing multi-factor authentication (MFA) for added security. Keep iDRAC firmware up to date to patch any known security vulnerabilities. Implement network segmentation to isolate the iDRAC network from the main production network to minimize the impact of a potential breach.
