9.2.3.1. Creating a Bootable USB Flash Drive by Using the
dd Command
On a Linux system, you can use the dd (http://manpages.ubuntu.com/manpages/bionic/en/
man1/dd.1.html) command to create a bootable USB flash drive that contains the DGX OS
software image.
Note: To ensure that the resulting flash drive is bootable, use the dd command to perform a
device bit copy of the image. If you use other commands to perform a simple file copy of the
image, the resulting flash drive may not be bootable.
Ensure that the following prerequisites are met:
‣
The correct DGX OS software image is saved to your local disk.
For more information, see Obtaining the Software ISO Image and Checksum File.
‣
The USB flash drive meets the following requirement:
‣
The USB flash drive has a capacity of at least 16 GB.
‣
This requirement applies only to DGX A100: The partition scheme on the USD flash
drive is a CPT partition scheme for UEFI.
1. Plug the USB flash drive into one of the USB ports of your Linux system.
2. Obtain the device name of the USB flash drive by running the lsblk (http://
manpages.ubuntu.com/manpages/bionic/man8/lsblk.8.html) command.
lsblk
You can identify the USB flash drive from its size, which is much smaller than the size of
the SSDs in the DGX software, and from the mount points of any partitions on the drive,
which are under /media.
In the following example, the device name of the USB flash drive is sde.
~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1.8T 0 disk
|_sda1 8:1 0 121M 0 part /boot/efi
|_sda2 8:2 0 1.8T 0 part /
sdb 8:16 0 1.8T 0 disk
|_sdb1 8:17 0 1.8T 0 part
sdc 8:32 0 1.8T 0 disk
sdd 8:48 0 1.8T 0 disk
sde 8:64 1 7.6G 0 disk
|_sde1 8:65 1 7.6G 0 part /media/deeplearner/DGXSTATION
~$
3. As root, convert and copy the image to the USB flash drive.
$ sudo dd if=path-to-software-image bs=2048 of=usb-drive-device-name
CAUTION: The dd command erases all data on the device that you specify in the of option
of the command. To avoid losing data, ensure that you specify the correct path to the USB
flash drive.
