Firmware upgrades
You can also verify synchronization status from the primary FIM Configuration Sync Monitor.
To re-synchronize the FortiGate-7081F, which has the effect of resetting the other FIM and the FPMs, re-install firmware
on the primary FIM.
1. Log into the primary FIM GUI.
2. Install a firmware build on the primary FIM from the GUI or CLI. The firmware build you install on the primary FIM
can either be the same firmware build or a different one.
Installing firmware synchronizes the firmware build and configuration from the primary FIM to the other FIM and the
FPMs.
3. Check the synchronization status from the Configuration Sync Monitor or using the diagnose sys confsync
status | grep in_sy command.
FortiGate-7081F 7.0.5 System Guide
You can also manually install firmware on each individual FIM and FPM from the BIOS after a
reboot. This manual process is just as effective as installing the firmware for a second time on
the primary FIM to trigger synchronization to the FIM and the FPMs, but takes much longer.
