Dell Server Deploy OS by IDRAC

Deploying an operating system (OS) using Dell iDRAC is a process that involves using iDRAC’s remote management capabilities, which can help you install the OS on a Dell server without physical access to the machine. This can be particularly useful in data centers or remote locations.

Here’s a step-by-step guide to deploy an OS using Dell iDRAC:

Prerequisites:

  1. Dell Server with iDRAC: Ensure that the server has a functional iDRAC (preferably iDRAC Enterprise for more advanced features).
  2. OS Installation Media: Have the OS installation media (ISO file or bootable USB) available.
  3. Network Connectivity: Ensure that iDRAC is accessible over the network and is configured with the proper IP address.
  4. iDRAC License: iDRAC Enterprise license is required for advanced features like virtual media.

Steps to Deploy OS Using iDRAC:

1. Access iDRAC Web Interface:

  • Open a web browser and enter the iDRAC IP address.
  • Log in with your username and password. The default username is usually root, and the default password is calvin unless it was changed during server setup.

2. Launch Virtual Console:

  • Once logged into iDRAC, go to the “Remote Control” section in the menu.
  • Click on “Launch Virtual Console”. This opens a new window that gives you access to the server’s console, just like being physically in front of the machine.

3. Mount OS Installation Media:

To install the OS, you need to mount the OS installation media (ISO file or bootable USB) to the server using iDRAC.

  • For ISO Installation:

    • In the Virtual Console window, click on the “Virtual Media” tab.
    • Choose “Connect Virtual Media” to open the Virtual Media menu.
    • Under the “Mapped Devices” section, click “Add Image” and browse to the ISO file of the operating system you want to install. Select the ISO file and click “Open”.
    • The ISO image will now be mounted to the server as a virtual CD/DVD drive.

  • For USB Installation:

    • If you are using a physical USB drive, ensure that the server is configured to boot from the USB drive (you may need to modify the boot order in the BIOS).
    • You can also mount USB devices through iDRAC using the “Virtual Media” section.

4. Reboot the Server and Enter BIOS/Boot Menu:

  • In the Virtual Console window, reboot the server by either selecting the “Power” option and choosing “Reboot” or by using the Ctrl+Alt+Del command within the console.
  • As the server restarts, press the appropriate key to enter the BIOS or Boot Menu (usually F2 for BIOS or F11 for Boot Menu, depending on your server model).
  • If you’re using an ISO, make sure the server is set to boot from the virtual CD/DVD drive (the mounted ISO) or USB device.

5. Select the Boot Device:

  • In the Boot Menu, select the Virtual CD/DVD (for ISO) or the USB device (for physical USB media) as the first boot option.
  • Press Enter to proceed.

6. Install the Operating System:

  • The server will now boot from the selected OS installation media.
  • Follow the standard installation procedure for the OS you’re deploying (e.g., Windows Server, Linux, etc.).
  • The installation process will guide you through partitioning the disk, configuring settings, and installing drivers.

7. Complete OS Installation:

  • Once the OS installation is complete, the server may automatically reboot.
  • Remove the virtual media (ISO or USB) from the virtual media settings in iDRAC to avoid booting from it again.
  • The server will now boot from the newly installed OS.

8. Post-Installation Configuration:

  • After the OS installation is finished, you may need to configure the server (e.g., setting up network settings, users, and domain settings).
  • You may also need to install additional drivers, which can be done using Dell’s OpenManage software or directly from the Dell support website.

Using iDRAC for Remote OS Installation:

The key feature of iDRAC that makes OS deployment easier is the Virtual Console and Virtual Media options. With these tools, even without physical access to the server, you can install or reinstall the operating system, manage BIOS settings, and troubleshoot hardware without leaving your office or data center.

Advantages of Deploying an OS via iDRAC:

  • No Physical Access Required: You can deploy an OS remotely without needing to be near the server.
  • Automated OS Deployment: iDRAC allows for automated OS installation, especially when combined with tools like Dell OpenManage or automated scripting.
