Sun SPARC Enterprise T5120 - ILOM Introduction

 

Sun SPARC Enterprise T5120 - ILOM Introduction

Abstract

UNIX Systems Manufacturers originated their markets as workstations, during a time when they used 32 bit systems and the rest of the PC market was concentrating on 8 and 16 bit systems, and some CPU vendors like Intel use segmentation to keep their 16 bit software alive while struggling to move to 32 bit architectures. Some of the original servers were stacked workstations on a rack in a cabinet. The former high-powered video cards were merely ignored, as remote management needed command line interfaces. Engineering quickly determined that console access needed to be built into a new class of systems: rack mounted servers. These early servers offered traditional ALOM compatibility shell as well as newer ILOM shell. The ALOM compatibility shell is quite functional.

Sun Enterprise T5120 LOM

The Sun Enterprise T5120 is a server with a second generation OpenSPARC processor. It comes with a Lights Out Management (LOM) capability referred to as Integrated Lights Out Management (ILOM.) The Advanced Lights Out Management (ALOM) shell may be it's default. Most remote systems management work can be done from the LOM. Oracle has an ILOM 3.0 manual. There are also manuals formerly published by Sun Microsystems for OpenBoot 3.x and OpenBoot 4.x manuals.

ILOM: Logging In

A 9600 Baud Serial Cable can be added to the Console port, to provide immediate access.

ILOM: Help Screen

The Console port, provides help screen, less reasonable from the ALOM:

-> help
The help command is used to view information about commands and targets

Usage: help [-o|-output terse|verbose] [<command>|legal|targets|<target>|<target> <property>]

Special characters used in the help command are
[]   encloses optional keywords or options
<>   encloses a description of the keyword
     (If <> is not present, an actual keyword is indicated)
|    indicates a choice of keywords or options

help <target>              displays description if this target and its properties
help <target> <property>   displays description of this property of this target
help targets               displays a list of targets
help legal                 displays the product legal notice

Commands are:
cd
create
delete
dump
exit
help
load
reset
set
show
start
stop
version

->

Note: ALOM functions & objects are flat; ILOM functions are consistent with hierarchical objects

ILOM: Setting the Date

The LOM Serial Port provides access to set the date, as it is likely not correct.:

-> show /SP/clock

 /SP/clock
    Targets:

    Properties:
        datetime = Mon May 10 14:36:06 2021
        timezone = EDT (America/New_York)
        uptime = 7 days, 03:28:24
        usentpserver = disabled

    Commands:
        cd
        set
        show

-> set /SP/clock datetime="051014402021"
Set 'datetime' to '051014402021'

-> show /SP/clock datetime

  /SP/clock
    Properties:
        datetime = Mon May 10 14:40:08 2021

->

ILOM: Show System Controller Network

The LOM can be enabled to perform DHCP, so access can be made over an ethernet cable.

-> show /SP/network

 /SP/network
    Targets:
        test

    Properties:
        commitpending = (Cannot show property)
        dhcp_server_ip = 192.168.1.254
        ipaddress = 192.168.1.110
        ipdiscovery = dhcp
        ipgateway = 192.168.1.254
        ipnetmask = 255.255.255.0
        macaddress = 00:14:4F:AC:0B:E7
        pendingipaddress = 192.168.1.110
        pendingipdiscovery = dhcp
        pendingipgateway = 192.168.1.254
        pendingipnetmask = 255.255.255.0
        state = enabled

    Commands:
        cd
        set
        show

ILOM: Access via TCP/IP

The LOM can be accessed over TCP/IP, over an ethernet cable, via a terminal package like PuTTY.

Conclusions

OpenSPARC Systems are very viable platforms, offering tremendous Lights Out Management capabilities. The most recent SPARC Systems have been the fastest platforms in the world for nearly 4 years, so there is a tremendous growth potential for migrating from these older Open Source SPARC platforms. Being based upon Open Hardware, Open Firmware, and Open Hardware - new hardware vendors can also create their own newer generation platforms, to meet their own requirements if the Light Out Management capabilities are not a requirement.
