Description
This article describes that In some cases, it can be necessary to simulate a crash on the FortiGate to see how the environment would respond to this event or how the SNMP manager would log it.
Scope
FortiGate v7.2.4 and 7.0.11, only VM versions.
Solution
A new set of commands allow the super admin user to simulate a kernel crash.
As a result, the FortiGate-VM will safely reboot without any adverse impact on the system.
In the console, the kernel crash output will be shown.
Fortigate-ESX # diagnose debug kernel sysrq ?
enable <----- Enable magic SysRq.
disable <----- Disable magic SysRq.
status <----- Show the status of magic SysRq.
command Magic SysRq command.
Fortigate-ESX # diagnose debug kernel sysrq enable
Fortigate-ESX # diagnose debug kernel sysrq status
Magic SysRq is enabled (val=0x8)
Fortigate-ESX # diagnose debug kernel sysrq command ?
crash <----- Perform a system crash.
Fortigate-ESX # diagnose debug kernel sysrq command crash
This operation will generate a kernel crash and cause the firewall to reboot.
