Using Lights Out Management and the System Controller from Solaris

This chapter explains how to use the LOM-specific commands available in Solaris for monitoring and managing a Sun Fire entry-level midrange systems system. To use these commands you should install the Lights Out Management 2.0 packages (SUNWlomr, SUNWlomu and SUNWlomm) from the Solaris Supplemental CD. Refer to To Install 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 is obtained from SunSolve and is installed on the Sun Fire entry-level midrange systems to make use of the latest LOM utility updates.

The chapter contains the following sections:

• Monitoring the System From Solaris
• Other LOM Tasks Performed From Solaris

LOM Command Syntax

lom [-c] [-l] [-f] [-v] [-t] [-a] [-G] [-X]
lom -e , [x] lom -A on|off  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 Solaris

There are two ways of interrogating the LOM device (System Controller) or of sending it commands to perform:

• By executing LOM commands from the lom> shell prompt

For information about how to do this, see Chapter 3.

• By executing LOM-specific Solaris commands from the UNIX # prompt

These commands are 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:

# man lom

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)). Alarm 3 is UNIX Running and is not user-configurable.

Viewing the Event Log (lom -e)

To see the event log, type:

# lom -e n,[x]

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)

# lom -e 11 LOMlite Event Log: Fri Jul 19 15:16:00 commando-sc lom: Boot: ScApp 5.13.0007, RTOS 23 Fri Jul 19 15:16:06 commando-sc lom: Caching ID information Fri Jul 19 15:16:08 commando-sc lom: Clock Source: 75MHz Fri Jul 19 15:16:10 commando-sc lom: /N0/PS0: Status is OK Fri Jul 19 15:16:11 commando-sc lom: /N0/PS1: Status is OK Fri Jul 19 15:16:11 commando-sc lom: Chassis is in single partition mode.

Checking the Fans (lom -f)

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 5 OK speed self-regulating 6 OK speed self-regulating 7 OK speed self-regulating 8 OK speed self-regulating 9 OK speed 100 % 10 OK speed 100 % #

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 E2900 System Service Manual or Sun Fire V1280/Netra 1280 Service Manual , as appropriate.

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 systems system internal voltage sensors.

To check the status of the supply rails and internal voltage sensors, type:

CODE EXAMPLE 5-5 Sample Output from the lom -v Command

# lom -v Supply voltages: 1 SSC1 v_1.5vdc0 status=ok 2 SSC1 v_3.3vdc0 status=ok 3 SSC1 v_5vdc0 status=ok 4 RP0 v_1.5vdc0 status=ok 5 RP0 v_3.3vdc0 status=ok 6 RP2 v_1.5vdc0 status=ok 7 RP2 v_3.3vdc0 status=ok 8 SB0 v_1.5vdc0 status=ok 9 SB0 v_3.3vdc0 status=ok 10 SB0/P0 v_cheetah0 status=ok 11 SB0/P1 v_cheetah1 status=ok 12 SB0/P2 v_cheetah2 status=ok 13 SB0/P3 v_cheetah3 status=ok 14 SB2 v_1.5vdc0 status=ok 15 SB2 v_3.3vdc0 status=ok 16 SB2/P0 v_cheetah0 status=ok 17 SB2/P1 v_cheetah1 status=ok 18 SB2/P2 v_cheetah2 status=ok 19 SB2/P3 v_cheetah3 status=ok 20 IB6 v_1.5vdc0 status=ok 21 IB6 v_3.3vdc0 status=ok 22 IB6 v_5vdc0 status=ok 23 IB6 v_12vdc0 status=ok 24 IB6 v_3.3vdc1 status=ok 25 IB6 v_3.3vdc2 status=ok 26 IB6 v_1.8vdc0 status=ok 27 IB6 v_2.4vdc0 status=ok System status flags: 1 PS0 status=okay 2 PS1 status=okay 3 FT0 status=okay 4 FT0/FAN0 status=okay 5 FT0/FAN1 status=okay 6 FT0/FAN2 status=okay 7 FT0/FAN3 status=okay 8 FT0/FAN4 status=okay 9 FT0/FAN5 status=okay 10 FT0/FAN6 status=okay 11 FT0/FAN7 status=okay 12 RP0 status=okay 13 RP2 status=okay 14 SB0 status=ok 15 SB0/P0 status=online 16 SB0/P0/B0/D0 status=okay 17 SB0/P0/B0/D1 status=okay 18 SB0/P0/B0/D2 status=okay 19 SB0/P0/B0/D3 status=okay 20 SB0/P1 status=online 21 SB0/P1/B0/D0 status=okay 22 SB0/P1/B0/D1 status=okay 23 SB0/P1/B0/D2 status=okay 24 SB0/P1/B0/D3 status=okay 25 SB0/P2 status=online 26 SB0/P2/B0/D0 status=okay 27 SB0/P2/B0/D1 status=okay 28 SB0/P2/B0/D2 status=okay 29 SB0/P2/B0/D3 status=okay 30 SB0/P3 status=online 31 SB0/P3/B0/D0 status=okay 32 SB0/P3/B0/D1 status=okay 33 SB0/P3/B0/D2 status=okay 34 SB0/P3/B0/D3 status=okay 35 SB2 status=ok 36 SB2/P0 status=online 37 SB2/P0/B0/D0 status=okay 38 SB2/P0/B0/D1 status=okay 39 SB2/P0/B0/D2 status=okay 40 SB2/P0/B0/D3 status=okay 41 SB2/P1 status=online 42 SB2/P1/B0/D0 status=okay 43 SB2/P1/B0/D1 status=okay 44 SB2/P1/B0/D2 status=okay 45 SB2/P1/B0/D3 status=okay 46 SB2/P2 status=online 47 SB2/P2/B0/D0 status=okay 48 SB2/P2/B0/D1 status=okay 49 SB2/P2/B0/D2 status=okay 50 SB2/P2/B0/D3 status=okay 51 SB2/P3 status=online 52 SB2/P3/B0/D0 status=okay 53 SB2/P3/B0/D1 status=okay 54 SB2/P3/B0/D2 status=okay 55 SB2/P3/B0/D3 status=okay 56 IB6 status=ok 57 IB6/FAN0 status=okay 58 IB6/FAN1 status=okay #

The information output from this command is also contained in the output from the Solaris prtdiag -v command.

Checking the Internal Temperature (lom -t)

To check the internal temperature of the system and also the system's warning and shutdown threshold temperatures, type:

CODE EXAMPLE 5-6 Sample Output from the lom -t Command

# lom -t System Temperature Sensors: 1 SSC1 t_sbbc0 36 degC : warning 102 degC : shutdown 107 degC 2 SSC1 t_cbh0 45 degC : warning 102 degC : shutdown 107 degC 3 SSC1 t_ambient0 23 degC : warning 82 degC : shutdown 87 degC 4 SSC1 t_ambient1 21 degC : warning 82 degC : shutdown 87 degC 5 SSC1 t_ambient2 28 degC : warning 82 degC : shutdown 87 degC 6 RP0 t_ambient0 22 degC : warning 82 degC : shutdown 87 degC 7 RP0 t_ambient1 22 degC : warning 53 degC : shutdown 63 degC 8 RP0 t_sdc0 62 degC : warning 102 degC : shutdown 107 degC 9 RP0 t_ar0 47 degC : warning 102 degC : shutdown 107 degC 10 RP0 t_dx0 62 degC : warning 102 degC : shutdown 107 degC 11 RP0 t_dx1 65 degC : warning 102 degC : shutdown 107 degC 12 RP2 t_ambient0 23 degC : warning 82 degC : shutdown 87 degC 13 RP2 t_ambient1 22 degC : warning 53 degC : shutdown 63 degC 14 RP2 t_sdc0 57 degC : warning 102 degC : shutdown 107 degC 15 RP2 t_ar0 42 degC : warning 102 degC : shutdown 107 degC 16 RP2 t_dx0 53 degC : warning 102 degC : shutdown 107 degC 17 RP2 t_dx1 56 degC : warning 102 degC : shutdown 107 degC 18 SB0 t_sdc0 48 degC : warning 102 degC : shutdown 107 degC 19 SB0 t_ar0 39 degC : warning 102 degC : shutdown 107 degC 20 SB0 t_dx0 49 degC : warning 102 degC : shutdown 107 degC 21 SB0 t_dx1 54 degC : warning 102 degC : shutdown 107 degC 22 SB0 t_dx2 57 degC : warning 102 degC : shutdown 107 degC 23 SB0 t_dx3 53 degC : warning 102 degC : shutdown 107 degC 24 SB0 t_sbbc0 53 degC : warning 102 degC : shutdown 107 degC 25 SB0 t_sbbc1 40 degC : warning 102 degC : shutdown 107 degC 26 SB0/P0 Ambient 29 degC : warning 82 degC : shutdown 87 degC 27 SB0/P0 Die 57 degC : warning 92 degC : shutdown 97 degC 28 SB0/P1 Ambient 27 degC : warning 82 degC : shutdown 87 degC 29 SB0/P1 Die 51 degC : warning 92 degC : shutdown 97 degC 30 SB0/P2 Ambient 27 degC : warning 82 degC : shutdown 87 degC 31 SB0/P2 Die 53 degC : warning 92 degC : shutdown 97 degC 32 SB0/P3 Ambient 29 degC : warning 82 degC : shutdown 87 degC 33 SB0/P3 Die 50 degC : warning 92 degC : shutdown 97 degC 34 SB2 t_sdc0 51 degC : warning 102 degC : shutdown 107 degC 35 SB2 t_ar0 40 degC : warning 102 degC : shutdown 107 degC 36 SB2 t_dx0 52 degC : warning 102 degC : shutdown 107 degC 37 SB2 t_dx1 54 degC : warning 102 degC : shutdown 107 degC 38 SB2 t_dx2 61 degC : warning 102 degC : shutdown 107 degC 39 SB2 t_dx3 53 degC : warning 102 degC : shutdown 107 degC 40 SB2 t_sbbc0 52 degC : warning 102 degC : shutdown 107 degC 41 SB2 t_sbbc1 42 degC : warning 102 degC : shutdown 107 degC 42 SB2/P0 Ambient 27 degC : warning 82 degC : shutdown 87 degC 43 SB2/P0 Die 54 degC : warning 92 degC : shutdown 97 degC 44 SB2/P1 Ambient 26 degC : warning 82 degC : shutdown 87 degC 45 SB2/P1 Die 53 degC : warning 92 degC : shutdown 97 degC 46 SB2/P2 Ambient 27 degC : warning 82 degC : shutdown 87 degC 47 SB2/P2 Die 51 degC : warning 92 degC : shutdown 97 degC 48 SB2/P3 Ambient 27 degC : warning 82 degC : shutdown 87 degC 49 SB2/P3 Die 51 degC : warning 92 degC : shutdown 97 degC 50 IB6 t_ambient0 29 degC : warning 82 degC : shutdown 87 degC 51 IB6 t_ambient1 29 degC : warning 82 degC : shutdown 87 degC 52 IB6 t_sdc0 68 degC : warning 102 degC : shutdown 107 degC 53 IB6 t_ar0 77 degC : warning 102 degC : shutdown 107 degC 54 IB6 t_dx0 76 degC : warning 102 degC : shutdown 107 degC 55 IB6 t_dx1 78 degC : warning 102 degC : shutdown 107 degC 56 IB6 t_sbbc0 51 degC : warning 102 degC : shutdown 107 degC 57 IB6 t_schizo0 48 degC : warning 102 degC : shutdown 107 degC 58 IB6 t_schizo1 53 degC : warning 102 degC : shutdown 107 degC

Viewing All Component Status Data and the LOM Configuration Data (lom -a)

To view all LOM status and configuration data, type:

# lom -a

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.

To turn an alarm on from the command line, type:

# lom -A on,n

where n is the number of the alarm you want to set: 1 or 2.

To turn the alarm off again, type:

# lom -A off,n

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 Solaris to the lom> prompt.

To change the default escape sequence, type:

# lom -X xy

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.

---

---

Note - 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 stop the LOM from sending reports to the console, type:

# lom -E off

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.

To turn serial event reporting on again, type:

# lom -E on

Upgrading the Firmware (lom -G filename)

For a full description, refer to Chapter 9.
