SmartWare Software Configuration Guide

5 • System image handling

 

 

Introduction

This chapter describes how to load, maintain, and update the various software images in the SmartNode. The SmartWare system software consists of the application image and the driver images. The images are stored in persistent (non-volatile) memory. The application image is the software which actually operates the SmartNode. Driver images are used to operate the various optional PMC interface cards.

This chapter includes the following sections:

Memory regions in Smartware

System image handling task list (see page 68)

Boot procedure and bootloader (see page 74)

Note Section “System image handling task list” on page 68 describes the standard way to upgrade the SmartWare. If you encounter problems that won’t let you upgrade using the standard method, refer to section “Factory configuration” on page 75.

Note Refer to appendix F, “Notes for upgrading from R3.10 to R3.20” on page 618 for information on converting from SmartWare release R3.10 to R3.20

Factory configuration (see page 75)

Patton SmartNode devices are shipped with default system software which is stored in persistent memory. Along with the default system software (application image and driver images), a factory configuration, factory- config, has been loaded into the SmartNode at the factory. This configuration file sets the initial basic operating parameters of the SmartNode, such as enabling the Ethernet ports, setting the default IP addresses and the DHCP server.

Other configuration files may be stored in the SmartNode persistent memory. A configuration file is an ordered list of commands. Some of the various configuration files are

factory-config (read-only)

startup-config

running-config

user-config1, user-config2, etc. (these are specific application configurations created by the user)

Backups of the configuration files can be stored on a remote trivial file transfer protocol (TFTP) server. The remote tftp server must be accessible via one of the SmartNode IP interfaces. Tftp cannot be used from the console interface.

The following sections focus on SmartWare memory regions, as well as the software components you can copy into the memory or move between a TFTP server and the memory of the SmartNode. As SmartWare uses a specific vocabulary in naming those software components, refer to appendix A, “Terms and definitions” on 644 to ensure that you understand the concepts.
