Dell SmartFabric OS10 User Guide Release 10.5.3

You can automatically install an OS10 image on a Dell ONIE-enabled device. This process is known as zero-touch install. After the device boots to ONIE: Install OS, ONIE auto-discovery follows these steps to locate the installer file and uses the first successful method:

1. Use a statically configured path that is passed from the boot loader.
2. Search file systems on locally attached devices, such as USB.
3. Search the exact URLs from a DHCPv4 server.
4. Search the inexact URLs based on the DHCP responses.
5. Search IPv6 neighbors.
6. Start a TFTP waterfall.

The ONIE automatic discovery process locates the stored software image, downloads and installs it, and reboots the device with the new image. Auto-discovery repeats until a successful software image installation occurs and reboots the switch.

ONIE discovery — Usage information

• All ONIE auto-discovery methods download and run only supported default file names, such as onie-installer. The required file names and search order are described on the Open Network Install Environment website at Image Discovery and Execution. For more information, see the Open Networking Hardware Diagnostic Guide on the Dell Technologies Support site.
• If you use a DHCPv4 server, ONIE auto-discovery obtains the hostname, domain name, Management interface IP address, and the IP address of the domain name server (DNS) from the DHCP server and DHCP options. It also searches SCP, FTP, or TFTP servers with the default DNS of the ONIE server. DHCP options are not used to provide the server IP.
• If you use a USB storage device, ONIE searches only FAT or EXT2 file systems for an OS10 image.

Example: OS10 automatic installation

1. On the TFTP server, rename the OS10 image to a supported installer file name, such as onie-installer, using the mv image-name default-filename command.

   mv PKGS_OS10-Base-10.3.1B.144-installer-x86_64.bin onie-installer

2. Boot up the switch in ONIE: Install mode to install an OS10 image.
