To understand the local options on the “Unit boot from” menu, you need to understand how the OnBoard handles software upgrades:
• The first time a new software version is downloaded and installed from Cyclades, the new image is stored as “Image2” in the flash memory and the configuration is changed so the OnBoard boots from “image 2.”
• The second time a new software version is downloaded and installed, the latest image is stored as “Image 1,” and the OnBoard configuration is changed to boot from “Image1.”
• Subsequent downloads are stored following the same pattern, alternating “Image1” with “Image2.”In the “Unit boot from” pull-down menu, the entry for the current boot image is selected by default.
•
• Image1:image_filename
• Image2:image_filenameThe word “image” is followed by the number, followed by a colon (:), followed by the name of the file, including the version number. The menu item has the following format:image1:zvmppconb.v version_numberimage1:zvmppconb.v100After one or more software upgrades have been performed, a second image also appears in the menu, for example:image1:zvmppconb.v100image2:zvmppconb.v101If you want to boot from another image than the one currently selected, you can select that image from the “Unit boot from” menu.
