diagnose debug enable
diagnose debug console timestamp enable
diagnose debug application hatalk -1 <----- HA formation issues
diagnose debug application hasync -1 <----- HA Sync issues.
diagnose debug disable <----- Command to disable the debug.
- Run the following on both Primary/Secondary units and collect the info:
get system performance status
get system status
get system ha status
diagnose sys ha status
diagnose sys ha history read
diagnose debug crashlog read
diagnose sys ha checksum show
execute ha synchro start
execute ha manage 0 or 1 <admin-user> <----- This command will switch from CLI of the Primary to Secondary.
diagnose sys ha dump 5
- Packet captures for seeing communication between HA ports:
diagnose hardware device nic <heart beats interface>
diagnose sniffer packet port_ha "" 4 <---port_ha should be the heart beats interface.
- Collect the FortiGate’s HA and System EVENT logs for both units downloaded from the GUI/FortiAnalyzer or syslog (remote) server.
