Managing SteelHeads : Upgrading Your Software
  
Upgrading Your Software
You can upgrade or revert to a backup version of the software in the Administration > Maintenance: Software Upgrade page.
The bottom of the page displays the software version history of the SteelHead, which includes the version number and the software installation date.
To find allowed upgrades between RiOS versions and recommended upgrade paths, use the Software Upgrade tool on the Riverbed Support Site at. The tool includes all of the recommended intermediate RiOS versions.
You can upgrade software on the ESX SteelHead-c and the SteelHead (virtual edition) appliance using this procedure. To upgrade the software on the AWS SteelHead-c, use the Riverbed Cloud Portal. For details, see the SteelHead Cloud Services User’s Guide.
To revert the RiOS version
1. Choose Administration > Maintenance: Software Upgrade to display the Software Upgrade page.
2. Under Software Upgrade, complete the configuration as described in this table.
Control
Description
Switch to Backup Version
Switches to the backup version on the next reboot.
Cancel
Cancels the software version switch on the next reboot.
To upgrade the RiOS version
1. Download the software image from the Riverbed Support site to a location such as your desktop. Optionally, in RiOS 8.5 and later, you can download a delta image directly from the Riverbed Support site to the SteelHead. The downloaded image includes only the incremental changes. The smaller file size means a faster download and less load on the network. To download a delta image, skip to Step 2.
2. Choose Administration > Maintenance: Software Upgrade to display the Software Upgrade page.
3. Under Install Upgrade, complete the configuration as described in this table.
Control
Description
From URL
Select this option and specify the URL.
Use one of the following formats:
http://host/path/to/file
https://host/path/to/file
ftp://user:password@host/path/to/file
scp://user:password@host/path/to/file
From Riverbed Support Site
Select this option and select the target release number from the drop-down list. The system uploads and installs the new image immediately after you click Install. To upload and install the image later, schedule another date or time before you click Install.
From Local File
Select this option and specify the path, or click Browse to go to the local file directory.
If you specify a file to upload in the Local File text box, the image is uploaded immediately; however, the image is installed and the system is rebooted at the time you specify.
Schedule Upgrade for Later
Schedules the upgrade process. Specify the date and time to run the upgrade: YYYY/MM/DD, HH:MM:SS.
Install
Click to install the software upgrade on your system, unless you schedule it for later.
The software image can be quite large; uploading the image to the appliance and installing it can take a few minutes. Downloading a delta image directly from the Riverbed Support site is faster because the downloaded image includes only the incremental changes.
As the upgrade progresses, status messages appear.
After the installation is complete, the system reminds you to reboot the appliance to switch to the new version of the software.
Cancel
Cancels your changes.
4. Choose Administration > Maintenance: Reboot/Shutdown and click Reboot.
The appliance can take a few minutes to reboot. This behavior is normal because 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 reboot, the Dashboard, Software Upgrade, and Help pages of the Management Console display the RiOS version upgrade.
