Hardware Watchdog Mechanism

To detect and respond to system hang conditions, the Enterprise 250 server features a hardware watchdog mechanism--a hardware timer that is continually reset as long as the operating system is running. In the event of a system hang, the operating system is no longer able to reset the timer. The timer will then expire and cause an automatic system reset, eliminating the need for operator intervention.

The hardware watchdog mechanism is not activated until you enable it.

To enable this feature, you must edit the /etc/system file to include the following entry:

set watchdog_enable = 1

This change does not take effect until you reboot the system.
