Performing A Fast Software Upgrade - Cisco 6500 Series Software Configuration Manual

Chapter 5 Configuring RPR and RPR+ Supervisor Engine Redundancy

Performing a Fast Software Upgrade

The fast software upgrade (FSU) procedure supported by RPR allows you to upgrade the Cisco IOS
image on the supervisor engines without reloading the system.
If you are performing a first-time upgrade to RPR from EHSA, you must reload both supervisor engines.
Note
FSU from EHSA is not supported.
To perform an FSU, perform this task:
Command
Step 1
Router# copy source_device:source_filename {disk0
| disk1}:target_filename
Or:
Router# copy source_device:source_filename
sup-bootflash:target_filename
Or:
Router# copy source_device:source_filename
{slavedisk0 | slavedisk1}:target_filename
Or:
Router# copy source_device:source_filename
slavesup-bootflash:target_filename
Step 2
Router# config terminal
Router(config)# config-register 0x2102
Router(config)# boot system flash
device:file_name
Step 3
Router# copy running-config start-config
Step 4
Router# hw-module {module num} reset
Step 5
Router# redundancy force-switchover

Purpose
Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the active supervisor engine.
Copies the new Cisco IOS image to the bootflash:
device on the active supervisor engine.
Copies the new Cisco IOS image to the disk0: device or
the disk1: device on the redundant supervisor engine.
Copies the new Cisco IOS image to the bootflash:
device on the redundant supervisor engine.
Configures the supervisor engines to boot the new image.
Saves the configuration.
Reloads the redundant supervisor engine and brings it
back online (running the new version of the Cisco IOS
software).
Note
Conducts a manual switchover to the redundant
supervisor engine. The redundant supervisor engine
becomes the new active supervisor engine running the
new Cisco IOS image. The modules are reloaded and the
module software is downloaded from the new active
supervisor engine.
The old active supervisor engine reboots with the new
image and becomes the redundant supervisor engine.

Performing a Fast Software Upgrade
Before reloading the redundant supervisor
engine, make sure you wait long enough to ensure
that all configuration synchronization changes
have completed.
To perform an EHSA to RPR FSU, use the reload
command in Step 5.
