1.0 Systems Affected

This package provides firmware for IBM Power 775 (9125-F2C)  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 a minimum HMC level of:  HMC V7  R7.3.0 Service Pack 4 with PTF MH01313_0515.

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.


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:

     02APXXX_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, 02AP730_067_045 and 02AP731_067_045 are different
service packs.

An installation is disruptive if:

              Example:  Currently installed release is AP730, new release is AP731                Example:  AP730_061_061 is disruptive, no matter what level of AP730  is currently
                                   installed on the system                  Example:  Currently installed service pack is AP730_120_120 and
                                     new service pack is AP730_152_130

An installation is concurrent if:

              Example: Currently installed service pack  is AP730_061_061,
                                 new service pack is AP730_070_061.

  • General Availability Level


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:  AP730_042.

5.0 Downloading the Firmware Package

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

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
