2.0 Important Information

 Support for EnergyScaletm and Active Energy Managertm

For more information on the energy management features now available, please see the  EnergyScaletm white paper.

Note 1:  The lowest power cap that Active Energy Managertm  will allow the user to set is below the power value that can be  guaranteed. To avoid error conditions, set the power cap above the power used by the system at maximum load.  See the EnergyScaletm white paper at the link above for more information on how to set the power cap.

Note 2: The Exhaust Heat Index (EHI), as shown on Active Energy Managertm, may read up to 21 degrees lower than the actual exhaust air temperature.

Signal Cable in an InfiniBand loop, and InfiniBand I/0 drawer power on/off

Recently, internal IBM testing has discovered a reliability issue when concurrently plugging signal cables in an InfiniBand loop, or when an InfiniBand I/O drawer in the loop is powered off, during system operation.  Until a new level of system firmware is released that fixes this issue, IBM recommends that you do not follow any procedures, either from service publications, or from the HMC, that indicate this can be done concurrently.  To avoid potential problems, ensure that all partitions that utilize the resources in the affected InfiniBand loop are shut down prior to taking any actions with the cabling, or powering down the InfiniBand I/O drawer.  In the rare event that an InfiniBand cable is accidentally unplugged, do not attempt to replug the cable without quiescing all partitions that are utilizing resources in any of the InfiniBand I/O drawers in the loop.

The exposure exists on a 8204-E8A system if you have external InfiniBand I/O drawers connected to a feature code/CCIN 5616, which is the Dual Port 12X InfiniBand/GX+ Card.
   In an AIX partition  on an 8204-E8A system, check for feature code/CCIN 5616 by running bothe of the following AIX commands:
      lscfg -vp | grep -p P1-C7
      lscfg -vp | grep -p P1-C8

If you have difficulty identifying the presence of these adapters in any system, contact support for assistance.

If an InfiniBand/GX+ adapter is found in any of the locations above, you should not concurrently plug InfiniBand signal cables or power off an I/O drawer on that InfiniBand loop.

When system firmware is released that includes a fix for this problem, it will be clearly documented in the firmware description section of the description document.

Memory Considerations for Firmware Upgrades

The increase in memory used by the firmware is due to the additional functionality in later firmware releases.

HMC-Managed Systems

For information concerning HMC releases and to access the HMC code packages, go to the following URL:  http://www14.software.ibm.com/webapp/set2/sas/f/hmc/home.html

NOTE:   You must be logged in as hscroot in order for the firmware installation to complete correctly.


3.0 Firmware Information and Description

Use the following example as a reference to determine whether your installation will be concurrent or disruptive.

Note:  The file names and service pack levels used in the examples are for clarification only, and are not
             necessarily levels that have been, or will be released.

An installation is disruptive if:

              Example:  Currently installed release is EL320, new release is EL330                Example:  EL320_120_120 is disruptive, no matter what level of EL320 is currently
                                   installed on the system                  Example:  Currently installed service pack is EL320_120_120 and
                                     new service pack is EL320_152_130

An installation is concurrent if:

              Example: Currently installed service pack  is EL320_126_120,
                                 new service pack is EL320_143_120.
 

System firmware file naming convention:

     01ELXXX_YYY_ZZZ

NOTE:  Values of service pack and last disruptive service pack  level (YYY and ZZZ) are only unique within a release level (XXX).  For example, 01EL320_067_045 and 01EL330_067_053 are different service packs.

Impact:  New                 Severity: New

Features and Functions:

  • Support for the creation of multiple virtual shared processor pools (VSPPs) within the one physical pool. (In order for AIX performance tools to report the correct information on systems configured with multiple shared processor pools, a minimum of AIX 5.3 TL07 or AIX 6.1 must be running.)
  • Support for the "hyperboot" boot speed option in the power on/off menu on the Advanced System Management interface (ASMI).
  • Support for the capability to move a running AIX or Linux partition from one system to another compatible system with a minimum of disruption. 
  • Support for the collection of extended I/O device information (independent of the presence of an operating system) when a system is first connected to an HMC and is still in the manufacturing default state. 
  • Support for EnergyScaletm and Active Energy Managertm.  For more information on the energy management features now available, please see the EnergyScaletm white paper
Note 1:  The lowest power cap that Active Energy Managertm  will allow the user to set is below the power value that can be  guaranteed. To avoid error conditions, set the power cap above the power used by the system at maximum load.  See the EnergyScaletm white paper at the link above for more information on how to set the power cap.

Note 2: The Exhaust Heat Index (EHI), as shown on Active Energy Managertm, may read up to 21 degrees lower than the actual exhaust air temperature.


4.0 How to Determine Currently Installed Firmware Levels

You can view the server's current firmware level on the Advanced System Management Interface (ASMI) Welcome pane.  It appears in the top right corner.   Example:  EL320_031.


5.0 Downloading the Firmware Package

The firmware is located at the web site:

       http://www14.software.ibm.com/webapp/set2/firmware/gjsn

Follow the instructions on this web page. You must read and agree to the license agreement to obtain the firmware packages.

In the drop-down box, choose the entry for your specific machine type and model.

You may download the rpm file for system firmware from this location to your server, an ftp server, or a CD-ROM. If your system is HMC-managed, you will also need to download the xml file located on the final download page.  Make sure the file names have the format 01EL3xx_yyy_zzz, with an extension of .rpm and .xml, before copying them to your server, an ftp server or CD-ROM.  If using a CD-ROM, copy the .rpm and .xml files to the CD-ROM using a local CD-ROM burner utility.

Another method is to download the ISO image and create a CD-ROM to use with your HMC.

Note: If your HMC is not internet-connected you will need to download the new firmware level to a CD-ROM or ftp server.


6.0 Installing the Firmware

The method used to install new firmware will depend on the release level of firmware which is currently installed on your server. The release level can be determined by the prefix of the new firmware's filename.

Example: ELXXX_YYY_ZZZ

Where XXX =  release level

Instructions for installing firmware updates and upgrades can be found in the Operations Guide for the Hardware Management Console and Managed Systems, see Chapter 9. Updates, section Mangaged Systems Updates.
