FIGURE 6-1 Sample LOM Device Event Log (Oldest Event Reported First)
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 -R option to the priocntl command in the script file called /etc/
rc2.d/S25lom.
This is the script that runs the LOM watchdog process:
When you have done this, LOM will restart the server whenever the watchdog times
out.
