Configuring Automatic Server Restart

You can configure automatic server restart (ASR) to restart a server automatically after a lockup. LOM has a watchdog process that, by default, expects to be patted every 10,000 milliseconds. If it does not receive a pat after 40,000 milliseconds (default), then LOM switches on the front and back fault LEDs and generates a LOM event report. However, it does not automatically restart the system unless you have configured it to do so.

▼To Configure the LOM ASR

●Add the -Roption to the priocntl command in the script file called /etc/ rc2.d/S25lom.

This is the script that runs the LOM watchdog process:

#priocntl -e -c RT lom -W on,40000,10000 -R on

When you have done this, LOM will restart the server whenever the watchdog times out.
