Description of Issue
Due to an incorrect partition of the flash storage device, the FortiGate 80C may fail to boot-up. The
flash disk capacity should be
7640MB
in size, devices that report a flash disk size of
7636MB
have a
hidden partition
(4MB)
which may prevent the FortiGate from booting up if it attempts to locate the
operating system image in this partition.
The FortiGate models that may be affected by this issue are as follows:
FG-80C (PN: P05403-05-xx or higher)
FG-80CM (PN: P05446-05-xx or higher)
FW-80CM (PN: P05405-06-xx or higher)
To identify the part number (PN) of a specific unit, either;
1) Check the label on the bottom of the unit
or
2) Use the “get system status” command from the CLI
The part number of a device can be identified using the following CLI command:
FGT80C3900000000 # get system status
*************
Serial-Number: FGT80C3900000000
*************
System Part-Number: P05403-05
If your FortiGate is within the affected part number range you can verify the flash disk size to know if
it is correct or if there is a hidden partition that may cause the device to fail to boot-up. Upon boot-
up the flash size may be reported
Boot up, boot device capacity: 4MB --- Incorrect, the device will not boot
Boot up, boot device capacity: 7636MB --- Incorrect
Boot up, boot device capacity: 7640MB --- Correct
