system flash
Use this command to change the currently active firmware partition or to display partition information stored on the flash drive.
FortiWeb appliances have 2 partitions that each contain a firmware image: one is the primary and one is the backup. If the FortiWeb appliance is unable to successfully boot using the primary firmware partition, it may boot using the alternative firmware partition. The second partition can contain another version of the firmware.
To use this command, your administrator account’s access control profile must have either w or rw permission to the mntgrp area. For details, see Permissions.
