8-4: Fast Software Upgrade (FSU) and Enhanced Fast
Software Upgrade (eFSU)
The Fast Software Upgrade (FSU) procedure supported by RPR enables you to upgrade
the Cisco IOS image on the Supervisor engines without reloading the system. To perform
an FSU complete the following steps:
Copy the IOS image to the active supervisor:
1.
(exec) copy source_device:source_filename {disk0 | disk1 | sup-
bootflash}:target_filename
Copies the new Cisco IOS image to the disk0: device or the disk1: or the bootflash:
device on the active Supervisor engine.
OR
Copy the IOS image to the redundant supervisor:
(exec) copy source_device:source_filename {slave-disk0 | slave-disk1 |
slavesup-bootflash}:target_filename
Copies the new Cisco IOS image to the disk0: device or the disk1: or the bootflash:
device on the redundant Supervisor engine.
After you copy the file to the appropriate location, make sure that it has synchro-
nized to both supervisors before moving to the next step by showing the appropriate
device or slave device.
Configure the system to boot from the new image:
2.
(global) boot system flash device:file_name
Command
(exec) show standby brief
