Server Administrator Services 45
• View and configure asset information for the system being monitored.
• View and set the Automatic System Recovery (OS watchdog timer) actions
for the system being monitored.
NOTE: Automatic System Recovery options may not be available because the
operating system watchdog timer is enabled in BIOS. To configure the auto
recovery options, the operating system watchdog timer must be disabled.
NOTE: Automatic System Recovery actions may not execute exactly per the
time-out period (n seconds) when the watchdog identifies a system that has
stopped responding. The action execution time ranges from n-h+1 to n+1
seconds, where n is the time-out period and h is the heart beat interval.
The value of the heart beat interval is 7 seconds when n <= 30 and 15 seconds
when n > 30.
NOTE: The functionality of the watchdog timer feature cannot be guaranteed
when an uncorrectable memory event occurs in the system DRAM Bank_1.
If an uncorrectable memory event occurs in this location, the BIOS code
resident in this space may become corrupted. Because the watchdog feature
uses a call to BIOS to effect the shutdown or reboot behavior, the feature may
not work properly. If this occurs, you must manually reboot the system.
Shutdown
Subtabs: Remote Shutdown | Thermal Shutdown | Web Server Shutdown
The Web Server Shutdown tab can be accessed only when you are logged in
to the Server Administrator Web Server. See "Managing Server Administrator
Web Server" for details.
Under the Shutdown tab, you can:
• Configure the operating system shutdown and remote shutdown options.
• Set the thermal shutdown severity level to shut down your system in the
event that a temperature sensor returns a warning or failure value.
NOTE: A thermal shutdown occurs only when the temperature reported by
the sensor goes above the temperature threshold. A thermal shutdown does
not occur when the temperature reported by the sensor goes below the
temperature threshold.
• Shut down the DSM SA Connection Service (Web server).
NOTE: The DSM SA Connection Service starts automatically after a reboot,
so you must shut down the DSM SA Connection Service every time a system
starts up.
