Firmware upgrades
In addition to introducing the basics of upgrading FortiGate-6000F firmware, this section describes how to:
l
Upgrade the firmware running on individual FPCs.
l
Upgrade the management board firmware from the BIOS and reset the configuration of all of the FPCs.
Firmware upgrade basics
The management board and the FPCs in your FortiGate-6000 system run the same firmware image. You upgrade the
firmware from the management board GUI or CLI just as you would any FortiGate product.
You can perform a graceful firmware upgrade of a FortiGate-6000 FGCP HA cluster by enabling
uninterruptible-
upgrade
and
session-pickup
. A graceful firmware upgrade only causes minimal traffic interruption. For more
information about graceful HA upgrades, see
.
Upgrading the firmware of a standalone FortiGate-6000, or FortiGate-6000 HA cluster with
uninterrupable-
upgrade
disabled interrupts traffic because the firmware running on the management board and all of the FPCs
upgrades in one step. These firmware upgrades should be done during a quiet time because traffic will be interrupted
during the upgrade process.
A firmware upgrade takes a few minutes, depending on the number of FPCs in your FortiGate-6000 system. Some
firmware upgrades may take longer depending on factors such as the size of the configuration and whether an upgrade
of the DP3 processor is included.
Before beginning a firmware upgrade, Fortinet recommends that you perform the following tasks:
l
Review the latest release notes for the firmware version that you are upgrading to.
l
Verify the recommended upgrade path, as documented in the release notes.
l
Back up your FortiGate-6000 configuration.
Fortinet recommends that you review the services provided by your FortiGate-6000 before a
firmware upgrade and then again after the upgrade to make sure that these services continue
to operate normally. For example, you might want to verify that you can successfully access
an important server used by your organization before the upgrade and make sure that you can
still reach the server after the upgrade and performance is comparable. You can also take a
snapshot of key performance indicators (for example, number of sessions, CPU usage, and
memory usage) before the upgrade and verify that you see comparable performance after the
upgrade.
Installing firmware on an individual FPC
You may want to install firmware on an individual FPC to resolve a software-related problem with the FPC or if the FPC
is not running the same firmware version as the management board. The following procedure describes how to transfer
