In any of these circumstances, when the
lomlited
daemon is not running and an
event affecting the fans or power supply occurs, the LOM device takes control of the
Serial A/LOM port and sends an event report onto that port. When it has sent the
report, the LOM device relinquishes control of the serial port. Note that this can
interfere with communication on the Serial A/LOM port (see note below).
Note –
LOM reports that occur when the
lomlited
daemon is not running can
interfere with communication on the Serial A/LOM port. If you do not have the
lomlited
daemon installed and enabled then, to prevent the LOM from
interrupting serial communication, either use the Serial B port as your console port
or turn off LOM event reporting (see “Stopping the LOM from Sending Reports to
the Serial A Port When the Daemon is not Running” on page 78”).
Capturing LOM Event Reports Passively on the
Serial A/LOM Port
To monitor LOM events as they occur, keep a terminal connected to Serial Port A.
For information about setting up serial connections to the Netra t1, see Chapter 6.
For information about using LOM commands to interrogate the LOM device, see
“Interrogating the LOM and Using it to Power Up or Reset the System” on page 79.
Stopping the LOM from Sending Reports to the
Serial A Port When the Daemon is not Running
LOM reports that occur when the
lomlited
daemon is not running can interfere
with information you are attempting to send or receive on the Serial A/LOM port.
If you do not have the LOM software installed or you have disabled the
lomlited
daemon, you might want to stop the LOM device from sending reports to the Serial
A/LOM port.
To do this, use the
lomctl
utility stored in the
/usr/bin
directory.
To turn off reporting to the serial port, type:
# lomctl serialeventsoff
