Enable the system watchdog. The system contains a standard hardware watchdog circuit that constantly monitors the CPU. If the CPU fails to show signs of life, the watchdog can independently trigger a system reboot. This command enables that function.
When the watchdog is enabled (sysconf appliance watchdog enable), look for the following syslog message:
kernel: iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0)
When it is disabled (sysconf appliance watchdog disable), look for this log entry
kernel: iTCO_wdt: Watchdog Module Unloaded.
The absence of these messages on a sysconf appliance watchdog enable and sysconf appliance watchdog disable suggests that the watchdog timer device driver did not load successfully at power up.
sysconf appliance watchdog enable
lunash:>sysconf appliance watchdog enable
