To upgrade RiOS software

4.
Reboot the appliance.
The software image is quite large; uploading the image takes a few minutes. On model 3020, 3520, 5520
6020, and 6120 appliances the software can take up to 4 minutes to boot when upgrading for the first time
to RiOS v5.5.x. This is normal behavior as the software is configuring the recovery flash device. Do not press
Ctrl-C, unplug, or otherwise shut down the system during this first boot. There is no indication displayed
during the system boot that the recovery flash device is being configured.
After the upload is complete, you are reminded to reboot the system to switch to the new version of the
software. After reboot, the software version is displayed on the Home page of the Management Console.
Downgrading the Software
If you are downgrading to a previous version of the Steelhead appliance software, you must downgrade to
a version of the software that has previously run on your machine. For example, you cannot upgrade from
v1.2.3 to v2.0 or v2.1 and downgrade to v1.2.8—you must downgrade to v1.2.3 and then upgrade to v1.2.8.
If you do not follow this step, the system discards your configuration and you cannot recover it.
If you inadvertently downgrade to a software version that is not running on your system, either go back to
a previously installed revision, or save the text results of a show running-configuration command before
downgrading, and apply it after the downgrade. For detailed information, see the Riverbed Command-Line
Interface Reference Manual.
