Burn the USM Appliance ISO Image to a USB Drive

Applies to Product: USM Appliance™ LevelBlue OSSIM®

This procedure is a prerequisite to updating USM Appliance offline or restoring the software on a hardware appliance to its factory settings. For details, see Update USM Appliance Offline or Restore Software on a USM Appliance Hardware.

Important: This process deletes all files stored on the USB device.

Prerequisite

You must have already downloaded the ISO image from LevelBlue. For instructions, see Download a USM Appliance ISO Image.

The procedure is different based on the operating system you use. Follow the steps accordingly.

To burn the ISO image from a Linux machine

  1. Insert the USB drive into the USB port on your computer.

  2. To copy the ISO image, open a terminal and run the following command

    sudo dd if=<USM_image.iso> of=<USB_device> bs=4M

    Replace <USM_image.iso> with the full path of the downloaded ISO image file, and <USM_device> with the USB device location.

    For example, if you save the image file in /home/user/temp/image.iso and the USB device location is /dev/sdb, the command would be

    sudo dd if=/home/user/temp/image.iso of=/dev/sdb bs=4M

  3. Eject the USB device.

To burn the image from a Mac OS X machine

  1. Insert the USB drive into the USB port on your computer.

  2. To list the devices connected to your computer, open a terminal and run the following command

    diskutil list

  3. To identify the USB device, look for DOS_FAT_32 as the disk type.

    The location of the USB device in the following illustration is /dev/disk1.

    Output from running "diskutil list"

  4. Before burning the image, unmount your USB device

    diskutil unmountDisk <USB_device_location>

    Following the example in above, the command would look like this

    diskutil unmountDisk /dev/disk1

  5. Copy the image

    sudo dd if=<USM_image.iso> of=<USB_device> bs=1m

    Where

    • <USM_image.iso> is the full path of the ISO image file.
    • <USM_device> is the USB device location.

    For example, if you save the image file in /home/user/temp/image.iso and the USB device location is /dev/disk1, the command would be:

    sudo dd if=/home/user/temp/image.iso of=/dev/disk1 bs=1m

  6. Eject the USB device

    diskutil eject <USB_device>

To burn the image from a Windows machine

  1. Insert the USB drive.

  2. If you haven't already, download Win32 Disk Imager from SourceForge and install it on your computer.

    Win32 Disk Imager is a tool for writing images to USB drives.

  3. Launch Win32DiskImager and select the image file.

    Win32 Disk Imager populates the Device field with the USB drive automatically.

    Win32 Disk Imager, select image file

  4. To verify that the ISO image is the correct one, select MD5 Hash.

    Win32 Disk Imager checks the image file and displays its MD5 checksum. Confirm that it matches the one received from Support.

  5. Click Write.

    Confirm while prompted.

  6. Exit Win32 Disk Imager after the progress completes.
  7. Eject the USB drive.
