About Reimaging the Appliance Software with a Disk Tool
The software on a Secure Web Gateway appliance can be reimaged using the mwg-edisk tool, which writes a software image to an embedded hardware device. This might be needed to recover an appliance after a disruption has happened.
The reimaging can be performed for the model E and F appliances, which are equipped with suitable devices.
You can use the tool if the version of the the Secure Web Gateway appliance software you are running is 8.2.8 or higher.
For more information, see Reimage the Appliance Software with the mwg-disk Tool and mwg-edisk Tool Commands.
