Automatic (zero-touch) installs of SmartFabric OS10 images are supported on Dell ONIE-enabled devices. Zero-touch allows you to install SmartFabric OS10 to several new switches simultaneously. After a device successfully boots to ONIE: Install OS, autodiscovery obtains the hostname, domain name, Management interface IP address, and the IP address of the DNS name servers on your network from the DHCP server and DHCP options. The ONIE autodiscovery process locates the stored software image, starts installation, and then reboots the device with the new software image.
If a USB drive is inserted during this time (using the process in section 2.2.1 above), autodiscovery searches the USB storage supporting FAT32 or EXT2 file systems. It also searches for SCP, FTP, or TFTP servers using the default DNS name, onie-server, for the server. DHCP options are not used to provide the IP address of any of these file servers. The auto discovery method repeats until a successful software image installation occurs and reboots the switch.
Steps for an HTTP zero touch installation are as follows:
- Install a Linux web server such as Apache, that a switch can access once it has obtained its IP address from a DHCP server.
- Copy the SmartFabric_OS10.bin installer file to the path shared by the web server, such as /var/www/html, and rename it onie-installer or another qualified filename as described in the ONIE User Guide.
- Create a DNS entry to resolve onie-server to the Linux web server address.
- Test web access to the SmartFabric OS10 installer file by entering http://onie-server/onie-installer into the web browser’s URL field on a system in the same IP subnet. The directory will open showing the installer file. Click the file to download a local copy. The test passes when the file successfully downloads.
- Perform the following with each switch to be installed with SmartFabric OS10:
- With ONIE installed on the switch (no operating system), connect the OOB port to the network containing the web server.
- Power up the switch. The switch automatically starts the autodiscovery and zero-touch installation.
- Once the switch installs SmartFabric OS10, the switch reboots to the OS10 login: prompt. The installation is complete.
