▼ To Check Whether the Fault LED and Alarms
Are On or Off
● Type:
Alarms 1, 2, and 3 are software flags. They are not associated with any specific
conditions, but are available to be set by your own processes or from the command
line. For more information, see “To Turn the Alarms On and Off (lom -A)” on
page 76.
▼ To Change the LOM Automatic Server Restart
Configuration (
lom -w )
For full information about enabling and using LOM’s automatic server restart (ASR)
process, see “To Configure the LOM ASR” on page 73.
● To find out how the LOM watchdog is currently configured, type:
The LOM watchdog is enabled by default when the Solaris environment 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.
