    example image

Environment:

Intel Embedded Server RAID Technology 2 (ESRT2)

Red Hat Enterprise Linux (RHEL) 6.x

NoteThe RHEL OS version must also be supported by the Intel® Server Board or System.

How to fix it:

Follow the steps below to prepare and load the driver during RHEL installation:

  1. Download the latest Intel ESRT2 Linux driver to a Linux system and unzip the package.
  2. Open a terminal with root privilege and navigate to the DUD folder in the unzipped package.
  3. Enter the following commands to prepare the driver image:
    mkdir image
    gunzip megasr-18.02.2019.0603-l-rhel69-ga-x86_64.img.gz
    (replace the filename with the desired OS version)
    mount -oloop megasr-18.02.2019.0603-l-rhel69-ga-x86_64.img imag
  4. Copy the content in the image directory to the root of an USB drive and change the USB volume label to OEMDRV. The content of the USB should look like below:
    example image
  5. Insert the USB drive to the Intel ESRT2 system and start the RHEL installation.
  6. Navigate to Red Hat Enterprise Linux and press E.

    NoteFor Intel Server Board S2600WF/S2600ST, you will also need to add nomodeset xdriver=vesa brokenmodules=ast to the end of the line mentioned above.
  9. Press B to continue.
  10. If you have labeled the USB drive as OEMDRV, select Use it when you see below screen then select No when prompted Do you have a driver disk? and proceed to Step 14:

  11. If you did not label the USB drive as OEMDRV in Step 4, select Yes when prompted Do you have a driver disk?
  12. Select the USB device to install the driver. In this example, this is /dev/sda
    example image
  13. Select No when prompted Do you wish to load any more driver disks? and proceed with the installation.
  14. You should now see the Intel ESRT2 RAID volume and install RHEL on to this volume.
