Re-Imaging the System from a USB Flash
Drive
These instructions describe how to re-image the system from a USB flash drive. For
information about how to restore the system remotely, see “Remotely Reimaging the System”.
Before re-imaging the system from a USB flash drive, ensure that you have a bootable USB
flash drive that contains the current DGX A100 software image.
1.
Plug the USB flash drive containing the OS image into the DGX A100 system.
2.
Connect a monitor and keyboard directly to the DGX A100 system.
3.
Boot the system and press F11 when the NVIDIA logo appears to get to the boot menu.
4.
Select the USB volume name that corresponds to the inserted USB flash drive and boot
the system from it.
5.
When the system boots up, select one of the following options from the GRUB menu:
•
Install DGX OS <version>: Install DGX OS and reformat data RAID
•
Install DGX OS <version> Without Reformatting Data RAID
•
Advanced Installation Options: Select if you want to install with an encrypted root
filesystem, then select one of the following options.
>
Install DGX OS <version> With Encrypted Root
>
Install DGX OS <version> With Encrypted Root and Without Reformatting Data RAID
If you are an advanced user who is not using the RAID disks as cache and want to keep
data on the RAID disks, select one of the Without Reformatting Data RAID options. See
“Retaining the RAID Partition While Installing the OS” for more information.
6.
Press Enter.
The DGX A100 system will reboot and proceed to install the image. This can take more than 15
minutes.
Note
: The Mellanox InfiniBand driver installation may take approximately 30 minutes, depending
on how may cards undergo a firmware update.
After the installation is completed, the system then reboots into the OS.
Refer to “First Boot Setup” for the steps to take when booting up the DGX A100 system for the
first time after a fresh installation.
