Installing PICOS on Bare Metal Switches
- Tracy Yang
Introduction
When using ONIE installer to install PICOS, the installer reinstalls the software, rebuilds all the PICOS file system. This can erase the configuration files and system logs from the previous installation.
After a successful ONIE installation of PICOS 4.x, the system generates multiple system partitions including PicOS (partition size: 2G), PicOS2 (partition size: 2G) and User-Data partitions. Among them, PicOS and PicOS2 are two independent system boot partitions. One of them is the active partition on which the running system resides, and the other is the inactive partition. The two-system-boot-partition feature allows the system to revert to a previous version of the installed software package when the it fails to upgrade PICOS by using upgrade2 command.
The ONIE installer removes all partitions to rebuild a brand new OS only when there is no User-Data partition. However, if there exists a User-Data partition (for example, install a new version 4.0.1 from the old one 4.0.0), the ONIE installer only rewrites the "PicOS" partition, installs the new installation package to this partition and sets the system on "PicOS" partition as the default and sole boot system.
User-Data partition is a reserved partition which is not affected by ONIE installer and upgrade unless user manually removes it. User-Data partition uses all the available space left on the disk. Users can use this partition to store files and data.
This document describes how to install PICOS 4.x software using ONIE installer.
Installation Notes and Tools
The installation methods used to install a new PICOS are traditional installation and nos-boot-mode installation. You can choose a suitable installation method that is convenient and appropriate for your installation environment.
- If you want to install PICOS through a console port, refer to sections Traditional Installation or Nos-boot-mode Installation.
- If you want to install the PICOS through a non-console port (through the management port), refer to section Nos-boot-mode Installation.
• You need to log in through the console port of the switch and perform the ONIE installation.
• Other NOSes including user data will be removed when install PICOS under ONIE environment.
• When the ONIE installer is used to downgrade the PICOS version from version 4.x to PICOS 3.x or lower versions, we first need to use ONIE to uninstall the higher version PICOS before proceeding with installing PICOS 3.x or a lower version. On the ARM platform, execute the onie_uninstaller command at the ONIE prompt to uninstall the current version PICOS. On the x86 platform, select the "ONIE: Uninstall OS" option in the GRUB menu to uninstall the current version PICOS.
• If you enter GRUB rescue mode and the switch has GPT format partition, you can use the following commands to reset the GRUB boot variable to enter ONIE GRUB and then install PICOS.
grub rescue> set prefix=(hd0,gpt2)/grub
grub rescue> set root=(hd0,gpt2)
grub rescue> insmod normal
grub rescue> normal
• Do not plug in the USB disk during onie-nos-installer process until ONIE starts up. If you have plugged in the USB disk before the installation operation, ONIE will find the installer on the USB disk when beginning the installation. On AS4610 series switches, when installation is complete, the installer will display: Please take out the usb disc, then remove the USB disk within 10 seconds after installation successful, and before machine restarts.
• All X86 platforms share one installation and upgrade package with the name fixed as: onie-installer-picos-VERSION-x86.bin, where VERSION is the release version. X86 platform are listed below:

What is ONIE
ONIE (Open Network Install Environment) is an open source project of OCP (Open Compute Project). ONIE provides the environment to install any network operating system on a bare metal network switch. ONIE liberates users from captive pre-installed network operating systems, like the Cisco IOS, and provides them with a choice.
ONIE is a small Linux operating system that comes pre-installed as firmware on bare metal network switches. ONIE acts as an enhanced boot loader, extending the features provided by U-Boot. ONIE is used to install Pica8 PICOS on compatible switches. The bare metal switches listed in the PICOS Hardware Compatibility List must be pre-loaded with ONIE prior to installing PICOS.
Traditional Installation

Manual Installation Process
The following example describes the installation of PICOS via manual installation method.
Step1
Make sure that the installation package of .bin file has been load to the server (server could be HTTP, TFTP, or an FTP server or the switch local directory depending on the actual installation environment).
Step2 Enter ONIE installation environment. The process is different on the following two types of platforms:
- ARM Platforms (AS4610 Series Switches)
a)
Verify that the switch is pre-loaded with ONIE, which will be used to load PICOS on the switch. Power on the switch and interrupt the boot sequence by pressing any key when the following line is shown:
Hit any key to stop autoboot:
b)
User will then reach the U-Boot command prompt indicated by ->. Run the printenv command at the U-Boot prompt. If the information displayed contains keywords like onie_initargs and onie_machine, the switch is pre-loaded with ONIE.

On x86 platform, it uses GRUB menu to install OS via ONIE.
a) Reboot the system, and enter ONIE installation environment from the GRUB menu:
+----------------------------------------------------------------------------+
| PicOS |
|*ONIE |
| |
| |
| |
| |
| |
| |

+----------------------------------------------------------------------------+
Use the ^ and v keys to select which entry is highlighted.
Press enter to boot the selected OS, `e' to edit the commands
before booting or `c' for a command-line.
b) From GRUB prompt, choose ONIE: Rescue to Install OS, boot ONIE in rescue mode.

Step3 Run onie-nos-install command as follows to manually install PICOS.
- Install via TFTP
ONIE# onie-nos-install tftp://<path to image>/PICOS.bin
- Install via FTP
When installing via FTP, you need to type username and password of the FTP server on which the image file is loaded.
ONIE# onie-nos-install ftp://username:password@<path to image>/PICOS.bin
- Install via HTTP
ONIE# onie-nos-install http://<path to image>/PICOS.bin
- Install from Local Directory
a) In ONIE rescue mode, copy the image file to the current directory.
ONIE# scp username@<path to image>/PICOS.bin .
b) Run onie-nos-install command to start installation.
ONIE# onie-nos-install PICOS.bin
For example,
ONIE:/ # onie-nos-install onie-installer-picos-4.0.0-8b1219e112-x86.bin discover: Rescue mode detected. No discover stopped. ONIE: Executing installer: onie-installer-picos-4.0.0-8b1219e112-x86.bin Verifying image checksum ... OK. Preparing image archive ... OK. [1] PICOS L2/L3 (default) [2] PICOS Open vSwitch/OpenFlow Enter your choice (1,2):1 PICOS L2/L3 is selected. ONIE installation will overwrite the configuration file of existing system. It is recommended to follow the upgrade procedure to upgrade the system. Press any key to stop the installation... 10 9 8 7 6 5 4 3 2 1 ...
The installer runs automatically, before start installation, it will prompt to choose the option to make PICOS to boot into L2/L3 or OVS mode. If not selected, then PICOS boots into L2/L3.
After finishing installation, the device reboots automatically, the system then comes up running the new network operating system.
NOTE：
|
Automatic Installation Process
The automatic installation process uses the DHCP message exchange process to download and install software packages.
Step1 Make sure the switch is connected to DHCP and HTTP servers and the PICOS installation software package is downloaded to the HTTP server.
a) DHCP server configuration: define the path of the installation package and then start DHCP server service:
host pica8-3922 {
hardware ethernet 70:72:cf:12:34:56;
fixed-address 192.168.2.50;
option default-url = "http://192.168.2.42/onie-installer-picos-4.0.0-8b1219e112-x86.bin";
}
b) Check if the .bin installation file is loaded onto the HTTP server:
root@dev:/var/www# ls index.html onie-installer-powerpc.bin
Step2 Install PICOS via ONIE. The process is different on the following two types of platforms:
- ARM Platforms (AS4610 Series Switches)
a)
Verify that the switch is pre-loaded with ONIE, which will be used to load PICOS on the switch. Power on the switch and interrupt the boot sequence by pressing any key when the following line is shown:
Hit any key to stop autoboot:
b)
User will then reach the U-Boot command prompt indicated by ->. Run the printenv command at the U-Boot prompt. If the information displayed contains keywords like onie_initargs and onie_machine, the switch is pre-loaded with ONIE.

The installation methods described in Traditional Installation must be performed through the console port. If you want to install the system through a non-console port, you can use the nos-boot-mode command described in this section.
Usage of nos-boot-mode command: admin@Xorplus$sudo nos-boot-mode USAGE install or uninstall NOS(es) SYNOPSIS nos-boot-mode [install|uninstall] DESCRIPTION install- Install NOS uninstall- Remove all NOS(es) including PICOS When nos-boot-mode install command is executed, PICOS will switch to ONIE install mode automatically, and the user should go on to complete the subsequent ONIE installation process, the detail steps are described below. When nos-boot-mode unsinstall command is executed, the system will remove all NOS(es) including PICOS from the device. Therefore, it is suggested to use the nos-boot-mode unsinstall command with caution. |
NOTE:
In PICOS 4.4.4.3, nos-boot-mode cancel is added. The usage of nos-boot-mode command is changed like below:
admin@Xorplus$sudo nos-boot-mode
USAGE
install or uninstall NOS(es)
SYNOPSIS
nos-boot-mode [install|uninstall|cancel]
DESCRIPTION
install- Install NOS
uninstall- Remove all NOS(es)
When nos-boot-mode install command is executed, users need to do reboot operation manually to enter the ONIE install process, then to complete the subsequent ONIE installation process.
When nos-boot-mode unsinstall command is executed, users need to do reboot operation manually to enter the ONIE uninstall process. This operation will result in all NOS(es) including PICOS being removed from the device. Therefore, it is suggested to use the nos-boot-mode unsinstall command with caution.
The command nos-boot-mode cancel is supported to cancel the nos-boot-mode install or nos-boot-mode uninstall operation before performing a manual reboot. It is important to execute the nos-boot-mode cancel command before committing to a manual reboot. Here is an example
admin@PICOS:~$ sudo nos-boot-mode cancel All pending operations are canceled.
- In PICOS 4.4.4.3, users need to do reboot operation manually to enter the ONIE install/uninstall process after execute the nos-boot-mode install or nos-boot-mode uninstall commands, which is different from other PICOS versions.
- After choosing nos-boot-mode as the install or uninstall mode but not executing a reboot, if you change your mind and decide to upgrade PICOS using upgrade, upgrade2, or nos-rollback, please execute nos-boot-mode cancel first.
- After choosing nos-boot-mode as the install (or uninstall) mode but not executing a reboot, if you change your mind and decide to do nos-boot-mode uninstall (or install), please execute nos-boot-mode cancel first.
Manual Installation Process
Step1 Make sure that the installation package of .bin file has been loaded to the server (server could be HTTP, TFTP, or an FTP server or the switch local directory depending on the actual installation environment).
Step2 Execute the nos-boot-mode install command to enter ONIE installation environment.
admin@Xorplus:~$ sudo nos-boot-mode install
Step3 Type “yes” when the below prompt is shown, which will take the system will to ONIE install mode.
Type 'yes' to install NOS! Type 'no' to exit [no]/yes:
Step4 Run onie-nos-install command as follows to manually install PICOS.
- Install via TFTP
ONIE# onie-nos-install tftp://<path to image>/PICOS.bin
- Install via FTP
When installing via FTP, you need to type in the username and password for the FTP server on which the image file is loaded.
ONIE# onie-nos-install ftp://username:password@<path to image>/PICOS.bin
- Install via HTTP
ONIE# onie-nos-install http://<path to image>/PICOS.bin
- Install from Local Directory
a) In ONIE rescue mode, copy the image file to the current directory.
ONIE# scp username@<path to image>/PICOS.bin .
b) Run onie-nos-install command to start installation.
ONIE# onie-nos-install PICOS.bin
For example,
ONIE:/ # onie-nos-install onie-installer-picos-4.0.0-8b1219e112-x86.bin discover: Rescue mode detected. No discover stopped. ONIE: Executing installer: onie-installer-picos-4.0.0-8b1219e112-x86.bin Verifying image checksum ... OK. Preparing image archive ... OK. [1] PICOS L2/L3 (default) [2] PICOS Open vSwitch/OpenFlow Enter your choice (1,2):1 PICOS L2/L3 is selected. ONIE installation will overwrite the configuration file of existing system. It is recommended to follow the upgrade procedure to upgrade the system. Press any key to stop the installation... 10 9 8 7 6 5 4 3 2 1 ...
The installer runs automatically, before start installation, it will prompt to choose the option to make PICOS to boot into L2/L3 or OVS mode. If not selected, then PICOS boots into L2/L3.
After finishing installation, the device reboots automatically, the system then comes up running the new network operating system.

Automated Installation Process
The automatic installation process uses the DHCP message exchange process to download and install software packages.
Step1 Make sure the switch is connected to DHCP and HTTP servers, and the PICOS installation software package is downloaded to the HTTP server.
a) DHCP server configuration: define the path of the installation package and then start DHCP server service:
host pica8-3922 {
hardware ethernet 70:72:cf:12:34:56;
fixed-address 192.168.2.50;
option default-url = "http://192.168.2.42/onie-installer-picos-4.0.0-8b1219e112-x86.bin";
}
b) Check if the .bin installation file is loaded onto the HTTP server:
root@dev:/var/www# ls index.html onie-installer-powerpc.bin
Step2 Execute the nos-boot-mode install command to enter ONIE installation environment.
admin@Xorplus$ sudo nos-boot-mode install
Step3 Type “yes” when the below prompt is shown, and the system will automatically complete the installation.
Type 'yes' to install NOS! Type 'no' to exit [no]/yes:
The installer runs automatically and will reboot the system after installation is completed.

Appendix: Troubleshooting Installation/Upgrade Failure on AS7326-56X
Installation or upgrade failure (for example, the switches cannot boot up after install) may occur on the old AS7326-56X hardware models (revision is R01F and before). When booting PICOS on AS7326-56X and detect hardware rev R01F, the system will log a warning message to prompt the hardware revision R01F is a pre-production hardware reversion: "This hardware revision R01F is a pre-production hardware rev, PICOS has applied a work around to work with PICOS. Support will be provided on a best effort basis".
To work around the issue, first we need to check the “Label Revision”. If it is an old hardware model (revision is R01F or before), then, we can perform the following provided solution after installation/upgrade to solve the problem.
Check Label Revision
Under ONIE prompt, run “onie_syseeprom” to get the “Label Revision”.
