The following describes the Dell diagnostics. These instructions apply to systems for which the ONIE diagnostics are not

available.

Topics:

• Downloading the Diagnostic Package

• Viewing the Dell DIAGs Versions

• Restoring the Factory Defaults

Downloading the Diagnostic Package

To download the diagnostic package on your system, follow these steps.

You must load or update the DIAG-OS (diag installer image) using the onie-nos-install command in ONIE Install or ONIE-

Rescue mode. The DIAG-OS installer runs in two modes: Update mode or Install mode. In Update mode, the DIAG-OS updates

the existing DIAG-OS and boots back to ONIE. In Install mode, the DIAG-OS erases the existing DIAG-OS and loads the new

DIAG-OS.

NOTE: If you have a recovery USB plugged into your system, you must remove it prior to installing the DIAG-OS using the

onie-nos-install command.

NOTE: Before you begin, go to http://www.dell.com/support and download the diagnostic package. You will need your

Dell support access account to download the package.

1 Enter the onie-discovery-stop command to stop ONIE Discovery mode.

2 Assign an ip address to the management interface and verify the network connectivity.

ONIE:/ # ifconfig eth0 10.10.10.10/8

ONIE:/ # ifconfig eth0

3 Upgrade the DIAG Installer. Again, boot to ONIE Rescue mode and install the onie diag installer.

Example of Removing the Existing DIAG OS and Installing a New Version

NOTE: In Install mode, the DIAG-OS installation removes any existing NOS and DIAG-OS partition. If you do not create

file /tmp/diag_os_install_mode, the DIAG-OS installs in Upgrade mode. In this case, the installation process

does NOT touch any existing NOS.
