Using LOMlite

LOMlite is supplied on a card as part of the system and provides lights out

management or remote management of the system over a serial connection. While the

system is running, LOMlite also provides event reporting via the Solaris operating

environment.

LOMlite Functionality

The alarms card implementing the LOMlite functionality can report errorconditions

in a number of ways:

■ The fault LED on the front panel will flash if any fan or PSU fails.

■ On the Netra t 1400, the current state of the supply A and supply B is indicated by

LEDs on the front panel.

■ Any fan failure or change of PSU state is reported on the LOMlite console and is

entered into the LOMlite’s event log. The first fatal error is preserved as a possible

root cause of subsequent failures.

The event log may be displayed using either the LOMlite console show command,

or the Solaris utility lominfo events utility. Once a fault has been cleared, the

event log can be cleared using the Solaris lomctl clearevents utility.

■ As events are entered into the LOMlite’s event log, they are also recorded by the

Solaris daemon, lomlited, in the system log files, according to the configuration

of syslogd. Typically, such messages are reported to the console.

■ The LOMlite console environment commands can be used to show the current

state of the fans and PSUs in the system.

■ The Solaris lominfo utility can be used to display the current state of the fans

and PSUs in the system.
