CMM ILOM Document Overview

This document is a supplement that contains information on ILOM updates specific to the Sun Blade 6000 and Sun Blade 6048 modular system CMM ILOM 3.x. This document also provides information on SNMP traps, PET traps, and ILOM sensors.

For information on CMM ILOM administration, see Oracle Lights Out Manager (ILOM) CMM Administration Guide.

For more detailed information on setting up and using the ILOM 3.x, refer to the documentation in the ILOM 3.0 Documentation Collection at:

http://docs.sun.com/app/docs/coll/ilom3.0

Note - The term blade module is used to refer to a module that could be either a server module or a storage module.

Key Updates for the CMM ILOM 3.x

Most updates for ILOM 3.x are described in the Sun Integrated Lights Out Manager (ILOM) 3.0 Feature Updates and Release Notes.

The following table lists additional key updates that are specific to the CMM ILOM 3.x:

Link to Update Information	Introduced in ILOM 3.x Version
Changes in Power Allocated to the Blade Modules	3.0.3
System Fan Speed Control Improvements	3.0.3
Force Power Supply Fans to Low Speed	3.0.6.11
Light Load Efficiency Mode (LLEM)	3.0.6.11
Power Management Disable Feature Available	3.0.6.11.c
Changing the Blade SP CLI Prompt	3.0.10
Component Firmware Update	3.0.10
Sun Blade Zone Manager	3.0.10

Changes in Power Allocated to the Blade Modules

There is a big change in ILOM 3.0 power allocation to the blade modules. In ILOM 2.0, a blade module determines if there is enough Permitted Power for all blade modules to power on; if there is not enough power, the blade module does not power on. For a rack with many high-powered blade modules, this results in no blade modules powering on.

In ILOM 3.0 (with ILOM 3.0 on both the CMM and on the blade modules), the blade module is allocated 0 Watts when it is powered off. When a blade module wants to power on, it contacts the CMM and requests some amount of power to be allocated to the slot. The CMM then allocates power to the slot and allows the blade module to power on. When a blade module powers off, it releases the power back to the CMM.

As a result, even if you have a rack full of high-powered blade modules, you can still power on some subset of blade modules. Once all permitted power is used up, you cannot power on any more blade modules until a running blade module is powered off. But once you power off one blade module, you’ll be able to power on another blade module.

System Fan Speed Control Improvements

There are some fan speed control improvements in ILOM 3.0 for CMM, when ILOM 3.0 is running on both the CMM and blade modules. In ILOM 2.0, the CMM sets the fan speed based on ambient temperature. In ILOM 3.0, the CMM uses feedback from the blade modules to determine the lowest fan speed that will maintain appropriate temperature for the blade modules.

This new fan speed control feature is only available if the CMM and all blade modules in the chassis are running ILOM 3.0.

Force Power Supply Fans to Low Speed

A new feature in ILOM 3.0.6.11 (SW 3.1) allows you to adjust of power supply fans to low speed.

Refer to the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for information.

Light Load Efficiency Mode (LLEM)

The Light Load Efficiency Mode (LLEM) is a new feature of CMM ILOM 3.0.6.11 that allows you to turn off individual power supply sides.

Refer to the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for information.

Power Management Disable Feature Available

A new power management option has been added to ILOM 3.0.6.11.c (Software Version 3.1.3), which enables the user to disable power management so that blades in the chassis attempts to power on even if power allocation has been exceeded.

This procedure must only be performed under the supervision of Oracle service personnel.

Refer to the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for information on this procedure.

Changing the Blade SP CLI Prompt

ILOM 3.0.10 (Software Version 3.2), includes an option for changing the blade SP CLI prompt through the CMM.

Refer to the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for information on this procedure.

Component Firmware Update

In ILOM 3.0.10 (Software Version 3.2), a component firmware updated option is available through the CMM. This provides a centralized user interface for viewing the firmware version installed and initiating firmware updates on blades and NEMs installed in the chassis.

Refer to the Oracle Integrated Lights Out Manager (ILOM) CMM Administration Guide for information on this procedure.

Sun Blade Zone Manager

In ILOM 3.0.10 (Software Version 3.2), the Sun Blade Zone Manager feature is available.

The Sun Blade Zone Manager enables you to assign storage devices in SAS-2 storage modules to SAS-2 enabled server blades. This feature is available only when SAS-2 server blades, storage blades, and NEMs are installed in the chassis. If the SAS-2 hardware environment is not available, the system displays the following error message:

The minimum set of SAS-2 hardware is not present or ready to support this operation.
