Remarks
This method is disruptive. You must reboot the
entire device to complete the upgrade.
Use this method when the device cannot start up
correctly.
IMPORTANT:
Upgrade an IRF fabric from the CLI rather than the
BooWare menus.
The BootWare menu method increases the service
downtime, because it requires that you upgrade
the member devices one by one.
