DIAG OS installation or update

Load or update the DIAG-OS—the diag installer image—using the onie-nos-install command. 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, remove it before using the onie-nos-install command.

NOTE: Before you begin, go to www.dell.com/support and download the diagnostic 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.

3 Upgrade the DIAG Installer.

Again, boot to ONIE Rescue mode and install the onie diag installer.

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.
