Chapter 9 Managing the Server From the Solaris Prompt 9-5
9.1.6 Checking the Status of the Fault LED and Alarms
(lom -l)
● To check whether the Fault LED and alarms are on or off, type:
Alarms 1, 2, and 3 are software flags. They are associated with no specific conditions
but are available to be set by your own processes or from the command line (see
Section 9.3.1, “Turning Alarms On and Off (lom -A)” on page 9-11).
9.1.7 Changing the LOM Automatic Server Restart
Configuration (lom -w)
For full information about enabling and using the LOM’s Automatic Server Restart
(ASR) facility, see Section 9.2, “Configuring Automatic Server Restart (ASR)” on
page 9-8.
● To find out how the LOM’s watchdog is currently configured, type:
The LOM’s watchdog is enabled by default when Solaris boots. This means that, by
default, if the watchdog does not receive a “pat” for 40,000 milliseconds, it will turn
on the Fault LED on the front and back panels of the system, generate a LOM event
report, and — if configured to do so — perform an automatic server restart.
However, although the watchdog is enabled by default when Solaris boots, the
Hardware reset option is not. This means that the LOM device does not, by
default, automatically restart the server after a lockup.
