3.Enable the server timeouts that correspond to the events that you want the Remote Supervisor Adapter II to respond to automatically.

POST watchdog

Use the POST watchdog field to specify the number of minutes that the Remote Supervisor Adapter II will wait for the server to complete a power-on self-test (POST). If the server that is being monitored fails to complete a POST within the specified time, the Remote Supervisor Adapter II generates a POST timeout alert and automatically restarts the server. The POST watchdog is then automatically disabled until the operating system is shut down and the server is power cycled (or until the operating system starts and the software is successfully loaded).

Note: Power cycling means that the server is turned off and then immediately turned on.

To set the POST timeout value, select a number from the menu. To turn off this option, select Disabled.

Note: If the POST Time-outcheck box is selected in the Remote Alerts area of the Remote Alerts page, the Remote Supervisor Adapter

IIattempts to forward the alert to all configured remote alert recipients. Also, the POST watchdog requires a specially constructed POST routine that is available only on specific IBM servers. If this routine does not exist on your server, all settings in this field are ignored.

For more information about POST routines, see the documentation that comes with your server.

O/S watchdog

Use the O/S watchdog field to specify the number of minutes between checks of the operating system by the Remote Supervisor Adapter II. If the operating system fails to respond to one of these checks, the Remote Supervisor Adapter II generates an O/S timeout alert and restarts the server. After the server is restarted, the O/S watchdog is disabled until the operating system is shut down and the server is power cycled.

To set the O/S watchdog value, select a time interval from the menu. To turn off this watchdog, select Disabled. To capture operating-system-failure screens, you must enable the watchdog in the O/S watchdog field and select the O/S Time-outcheck box in the Remote Alerts area of the Alerts page.

Notes:

a.The O/S watchdog feature requires that the Remote Supervisor Adapter II software be installed on the server. For information about installing this software, see the Remote Supervisor Adapter II Installation Guide.

b.If the O/S Time-outcheck box is selected in the Remote Alerts area of the Alerts page, the Remote Supervisor Adapter II will attempt to send an alert to all configured remote alert recipients.
