To Boot from an Alternate Image Using CLIIf, for any reason, you want to change to another image from the current one, if you have access to the Web Manager, you can use the Config Æ Boot Configuration screen to select the other image, and then use the “Restart” button on the Mgmt Æ Restart screen to boot the OnSite from the new location.
• Use the CLI utility
1. Connect to the OnSite from a terminal connected to the console port or create a telnet or ssh connection, and log in as root.
2. Enter the CLI command.
# CLIThe cli> prompt appears.
3. Enter config administration bootconfig.
cli> config administration bootconfigThe bootconfig> prompt appears.
4. Enter the bootunit keyword followed by the Tab key to see the list of possible boot values
If you type a unique string of characters from the image name and then press the Tab key, it autocompletes the name for you. For example, typing bootunit image2 and pressing Tab causes the full file name image2:zvmppcons.v101 to be filled in, as shown in the following screen example.
bootconfig> bootunit image2:zvmppcons.v101The currentimage environment variable is changed to boot from the specified image.
