Using the SCC upgrade and downgrade appliance wizard
SCC includes a wizard to upgrade and downgrade SteelHead RiOS images. To ensure authenticity and security, Riverbed software images are signed. See the SCC Best Practices chapter in the SteelCentral Controller for SteelHead User Guide for more information.
Several tasks are involved to upgrade and downgrade:
1. Specify the image library.
2. Configure upgrade or downgrade job.
3. Configure the reboot job parameter, which enables that image to run on the specific appliance.
Each specific task has its own dashboard as shown in.
Use the following methods to identify the image libraries available for use:
• Host the images stored locally - Local image storage is a process in which you can upload various RiOS images to the local storage of the SCC. You either browse a directory to the image or use a URL to the image and upload it to the SCC. When you use this method, the SCC holds the various images and makes them available for distribution to various other appliances according to the upgrade job parameters.
• Customer-defined URL links - Instead of locally storing the images on the SCC itself, you can provide a URL where various images are located. This method doesn’t upload the images to the SCC locally but serves as a trusted pointer to an available remote resource.
• Integrate available images directly from Support - The SCC validates (according to the software entitlement program) available images for use with any of the managed devices in its inventory. This method provides all the images available that the SteelHead can access from the Support portal. You can download the chosen image directly to the SteelHead; however, you can’t store the image locally on the SCC.
Use the Jobs Wizard to guide you through the process. Consider the outcome you want to achieve prior to starting the wizard: for example, upgrading a certain set of appliances to a certain code version. To open the Jobs Wizard, choose Manage > Upgrades: Upgrade Appliances (or Downgrade Appliances) > Launch new upgrade job....
The Jobs Wizard guides you to:
1. choose the product to upgrade: for example, SteelHead, SteelHead EX, or SteelHead Interceptor.
2. target the product version (this information is provided from the image library result of the previous task).
3. select the appliances (the Jobs Wizard displays available licenses compatible with choices selected).
4. choose the upgrade settings: for example, notes about the upgrade job, upgrade time, reboot options, and so on.
5. view the summary page to review your selections.
6. initiate the upgrade or downgrade job.
The downgrade image must exist locally on the SCC or referenced as a customer-defined URL. You can’t point to referenced images on the Support site for downgrade jobs.
