Applies to: 9119-FHB
This document provides information about the installation of
Licensed
Machine or Licensed Internal Code, which is sometimes referred to
generically
as microcode or firmware.
Contents
This package provides firmware for Power 795 (9119-FHB) Servers
only. Do not use on any other systems.
The firmware level in this package is:
HMC-Managed Systems
This firmware level requires HMC V7 R7.2.0.
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.
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:
02ABXXX_YYY_ZZZ
- XXX is the release level
- YYY is the service pack level
- ZZZ is the last disruptive service pack level
NOTE: Values of service pack and last disruptive service
pack level (YYY and ZZZ) are only unique
within a release level (XXX). For example, 02AB720_067_045 and
02AB730_067_053 are different
service packs.
An installation is disruptive if:
- The release levels (XXX) are different.
Example: Currently installed release is AB720, new release is
AB730
- The service pack level (YYY) and the last
disruptive service pack level (ZZZ) are equal.
Example: AB720_061_061 is disruptive, no matter what level of
AB720
is currently
installed on the system
- The service pack level (YYY) currently installed on the system
is lower than the last disruptive service pack level (ZZZ) of the
service pack to be installed.
Example: Currently installed service pack is AB720_120_120 and
new service pack is AB720_152_130
An installation is concurrent if:
- The service pack level (YYY) is higher than the service
pack level currently installed on your system.
Example: Currently installed service pack is AB720_061_061,
new service pack is AB720_070_061.

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: AB720_061.
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.
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: ABXXX_YYY_ZZZ
Where XXX = release level
- If the release level will stay the same (Example: Level
AB720_061_061 is currently installed and you are attempting to
install level AB720_081_061) this is considered an update.
- If the release level will change (Example: Level AB720_061_061
is currently installed and you are attempting to install level
AB730_096_096) this is considered an upgrade.
