Interacting with the ELOM/ILOM

ELOM is the older version of the service processor's firmware while ILOM is the name of the current versions.

ILOM

The following is valid for version

SP firmware 2.0.2.6
SP firmware build number: 35128
SP firmware date: Mon Jul 28 10:17:35 PDT 2008
SP filesystem version: 0.1.16

Show the status of the running system

This will also print whether the system is on or off.

show /SYS

Starting/stopping system

start /SYS
stop /SYS
stop -force /SYS
reset /SYS

Viewing the SP logs

Many important things in respect to HW are recorded in the Service Processor logs

show /SP/logs/event/info

Preparing to remove a component (e.g. removing a blade from enclosure)

The prepare_to_remove_action of the component should show a ready status. This is also reflected by a blue LED lighting up on the blade server.

For taking out a blade from a blade center, after shutting down the OS, log in to the blade's ILOM and execute

set /SYS prepare_to_remove_action=true
 

Rebooting the SP

reset /SP

Reading out temperature sensors with ILOM

show /SYS/MB/T_AMB0
...
show /SYS/MB/T_AMB3
show /SYS/T_AMB
show /SYS/PS0/T_AMB
show /SYS/PS1/T_AMB

starting the console redirection

start /SP/console

Rebooting the SP

reset /SP

show SP network settings

show /SP/network

Show SP serial connection settings

Accessing the SP's embedded Linux

The ILOM is run by a custom Linux on the service processor. It is possible to access it by logging using the sunservice account:

ssh sunservice@mangm-interface

Note that SUN has placed the following warning as login message:

WARNING: The "sunservice" account is provided solely to allow
Sun Services to perform diagnosis and recovery tasks. Customer use of
the "sunservice" account may interfere with the correct operation of
ILOM and is not supported other than to perform recovery procedures as
documented by Sun Microsystems. Normal ILOM operations should always be
performed using the root account. Further usage of the "sunservice"
account implies your agreement with these terms.

Blade Center Chassis

ILOM network configuration

MAC addresses of the blade enclosures were given in the delivery notes coming with the hardware. Configure the dhcp server to assign an IP to this address. Then log into the chassis ILOM.

The chassis network information can be listed through

show /CH/CMM/NET0

Finding each blade servers' MAC address (here for blade server 0):

show /CH/BL0/SP/network
