9.2 Configuring Automatic Server Restart
(ASR)
You can configure the LOM device to restart the server automatically after a lockup.
The LOM device 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), the
LOM device turns the front and back fault LEDs on and generates a LOM event
report. However, it does not automatically restart the system unless you have
configured it to do so.
9.2.1 Configuring the LOM Watchdog to Restart the
System After a Lockup
● 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, the LOM device will restart the server whenever the
watchdog times out.
You can turn the option on and off from the Solaris command prompt. For more
information, see Section 9.2.3, “Setting the Hardware Reset Option From a Script or
Command (lom -R on)” on page 9-10.
However, as long as you have the -R on option set in /etc/rc2.d/S25lom, the
Hardware Reset option will always be enabled when you start the system.
