Using Lights Out Management and the System Controller From the Solaris OS
|
This chapter explains how to use the LOM-specific commands available in the Solaris OS for monitoring and managing a Sun Fire entry-level midrange system. To use these commands, you should install the Lights Out Management 2.0 packages (SUNWlomr, SUNWlomu and SUNWlomm) from the Solaris Supplemental CD. See Installing the Lights Out Management Packages for a description of how to install the LOM packages.
Note - The latest patches to these packages is available from SunSolve in patch 110208. It is strongly advised that the latest version of patch 110208 be obtained from SunSolve and be installed on the Sun Fire entry-level midrange system to make use of the latest LOM utility updates.

This chapter includes the following topics:
LOM Command Syntax
lom [-c] [-l] [-f] [-v] [-t] [-a] [-G] [-X]
lom -e <n>, [x]
lom -A on|off <n>
lom -E on|off
where:
-c displays LOM configuration.
-l displays the status of the Fault and Alarms LEDs.
-e displays the event log.
-f displays fan status. This information is also displayed in the output from the Solaris prtdiag -v command.
-v displays the status of the voltage sensors. This information is also displayed in the output from the Solaris prtdiag -v command.
-t displays temperature information. This information is also displayed in the output from the Solaris prtdiag -v command.
-a displays all component status data.
-A turns alarms on and off.
-X changes the escape sequence.
-E switches event logging to the console on and off.
-G upgrades the firmware.
Monitoring the System From the Solaris OS
There are two ways of interrogating the LOM device (SC) or of sending it commands to perform:
- By executing LOM commands from the lom> shell prompt (see Chapter 3).
- By executing LOM-specific Solaris commands from the UNIX # prompt as described in this chapter.
The Solaris commands described in this section, which are all available from the UNIX # prompt, run the /usr/sbin/lom utility.
Where appropriate, the command lines given in this section are accompanied by typical output from the commands.
Viewing Online LOM Documentation
To view the manual pages for the LOM utility, type:
Viewing the LOM Configuration (lom -c)
To view the current LOM configuration, type:
CODE EXAMPLE 5-1 Sample Output from the lom -c Command
# lom -c
LOM configuration settings:
serial escape sequence=#.
serial event reporting=default
Event reporting level=fatal, warning & information
firmware version=5.17.0, build 5.0
product ID=Netra T12
|
Checking the Status of the Fault LED and Alarms (lom -l)
To check whether the System Fault LED and alarms are on or off, type:
CODE EXAMPLE 5-2 Sample Output from the lom -l Command
# lom -l
LOM alarm states:
Alarm1=off
Alarm2=off
Alarm3=on
Fault LED=off
#
|
Alarms 1, and 2 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 Turning Alarms On and Off (lom -A)). For information about alarm 3 (the system alarm) and its relation to the watchdog timer, see Programming Alarm 3.
Viewing the Event Log (lom -e)
To see the event log, type:
where n is the number of reports (up to 128) that you want to see and x specifies the level of reports you are interested in. There are four levels of event:
1. Fatal events
2. Warning events
3. Information events
4. User events (not used on Sun Fire entry-level midrange systems systems)
If you specify a level, you will see reports for that level and above. For example, if you specify level 2, you will see reports of level 2 and level 1 events. If you specify level 3, you will see reports of level 3, level 2, and level 1 events.
If you do not specify a level, you will see reports of level 3, level 2, and level 1 events.
CODE EXAMPLE 5-3 shows a sample event log display.
CODE EXAMPLE 5-3 Sample LOM Event Log (Oldest Event Reported First)

To check status of the fans, type:
CODE EXAMPLE 5-4 Sample Output From the lom -f Command
# lom -f
Fans:
1 OK speed self-regulating
2 OK speed self-regulating
3 OK speed self-regulating
4 OK speed self-regulating

If you need to replace a fan, contact your local Sun sales representative and quote the part number of the component you need. For information, see the Sun Fire V1280/Netra 1280 Service Manual.
The information output from this command is also contained in the output from the Solaris prtdiag -v command.
Checking the Internal Voltage Sensors (lom -v)
The -v option displays the status of the Sun Fire entry-level midrange system internal voltage sensors.

Viewing all Component Status Data and the LOM Configuration Data (lom -a)
To view all LOM status and configuration data, type:
Other LOM Tasks Performed From Solaris
This section explains how to:
- Turn the alarm indicators on and off
- Change the LOM escape sequence
- Stop the LOM from sending reports to the console
- Upgrade the firmware
Turning Alarms On and Off (lom -A)
There are two alarms associated with the LOM. They are associated with no specific conditions but are software flags available to be set by your own processes or from the command line.
1. To turn an alarm on from the command line, type:
where n is the number of the alarm you want to set: 1 or 2.
2. To turn the alarm off, type:
where n is the number of the alarm you want to turn off: 1 or 2.
Changing the lom> Prompt Escape Sequence
(lom -X)
The character sequence #. (hash, dot) enables you to escape from the Solaris OS to the lom> prompt.
To change the default escape sequence, type:
where xy are the alpha-numeric characters you want to use.
Note - Quotes may be required for special characters to be interpreted by the shell.
|
If you are typing at the console and type the first character of the escape sequence, there is a one-second delay before the character appears on the screen. This is because the system waits to see if the next character in the escape sequence is about to be typed. If all the characters in the escape sequence are typed then the lom> prompt appears. If the next character to be typed is not the next character in the escape sequence, then the characters belonging to the escape sequence that were typed are output to the screen.
Stopping LOM From Sending Reports to the Console When at the LOM Prompt (lom -E off)
LOM event reports can interfere with information you are attempting to send or receive on the console.
To prevent LOM messages displaying when you are at the LOM prompt, turn off serial event reporting. This is equivalent to the seteventreporting command described in the Sun Fire Entry-Level Midrange System Controller Command Reference Manual.
1. To stop the LOM from sending reports to the console, type:
2. To turn serial event reporting on, type:
Upgrading the Firmware (lom -G filename)
