Chapter 6  Fabric Switch Maintenance

This chapter includes basic information about the OpenArchitect switch environment including 
an overview of the file system structure, modifying and updating switch files, upgrading the 
switch driver and kernel, and implementing a system recovery.

Overview of the OpenArchitect switch boot process

The OpenArchitect switch is equipped with a Random Access Memory (RAM) disk and three 
Read-Only Memory (ROM) devices, including, a boot ROM and two application flash devices.

Figure 6.1: ROM Devices in Open Architect

The boot ROM is located on device 0 and contains the OpenArchitect 

zmon

 application that 

operates as a boot loader and includes a device bootstring. Device 1 contains the application 
flash 1 image of the Linux operating system and the OpenArchitect overlay file system. 
Application flash 1 is the primary working image for the switch. Device 2 contains the 
application flash 2 that is an exact copy of application flash 1. You would only boot from this 
device if application flash 1 is corrupted and you need to restore the switch to the factory-shipped 
configuration.
