Technical Tip: HA not synced after 'config firewall schedule onetime' when 'set cfg-save manual'

HA will not sync automatically in the steps below:

• Setup cfg-save manual:

config system global
    set cfg-save manual
end

• Edit 'onetime' schedule object for firewall policy:

config firewall schedule onetime
    edit "test"
        set start 15:13 2025/06/04
        set end 16:13 2025/06/17
    next
end

config firewall policy
    edit 2
        set name "1111"
        set srcintf "port10"
        set dstintf "port11"
        set action accept
        set srcaddr "all"
        set dstaddr "all"
        set schedule "test"
        set service "ALL"
        set logtraffic disable
        set nat enable
    next
end

• HA will not automatically sync after selecting 'Save staged changed' from GUI. 

Workaround:

• Run the below CLI command in HA master:

diagnose sys ha checksum recalculate
