1.0 Systems Affected

This package provides firmware for Power 575 (9125-F2A)  Servers only.  Do not use on any other systems.
 

The firmware level in this package is:

2.0 Important Information

HMC-Managed Systems

This firmware level requires  HMC V7  R3.3.0  with MH01119 and MH01130.

Go to the following URL to access the HMC code packages:

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


WARNING: This Power Subsystem Firmware Update (EP330_054) MAY be Disruptive!

NOTE: If the Power Subsystem is being updated from EP330_049 then this update is concurrent, otherwise this update is DISRUPTIVE!

To install the Power Subsystem Firmware and System Firmware follow the instructions below:
  1. Power off all of the 9125-F2A Managed Systems
  2. Update the Managed Frame firmware ONLY (during this step the Managed Systems will transition from "Power Off" to "No Connection" and then back to "Power Off")
  3. Wait for all 9125-F2A Managed Systems to return to the "Power Off" state
  4. Cycle the Managed Frame's UEPO switch (Turn the Red Switch Off ; wait one minute ; Turn the Red Switch back On)
  5. Wait for the Managed Frame to return to the "Standby/Standby" state
  6. Update the firmware for each Managed System (Managed Systems should still be in "Power Off" state during firmware update)
  7. Power on the Managed Systems

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 following examples are for clarification only, and are not
             necessarily levels that have been, or will be released.

Power Subsystem firmware file naming convention:

     02EPXXX_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, 02EP330_067_045 and 02EP340_067_053 are different
service packs.

An installation is disruptive if:

              Example:  Currently installed release is EP330, new release is EP340                Example:  EP330_120_120 is disruptive, no matter what level of EP330  is currently
                                   installed on the system                  Example:  Currently installed service pack is EP330_120_120 and
                                     new service pack is EP330_152_130

An installation is concurrent if:

              Example: Currently installed service pack  is EP330_126_120,
                                 new service pack is EP330_143_120.

4.0 How to Determine Currently Installed Power Subsystem Firmware Levels

You can view the frame's current firmware level on the Advanced System Management Interface (ASMI) Welcome pane.  It appears in the top right corner.   Example:  EP330_029.

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 individual .rpm and .xml files for Power Subsystem firmware from this location to your server, an ftp server, or a CD-ROM (both files are required).  Make sure the file names have the format 02EP3xx_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 file 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: EPXXX_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 Managed Systems Updates.

See Chapter 9. Updates, section Mangaged Systems Updates.
