1.0 Systems Affected

This package provides firmware for Power 775 (9125-F2C) Servers only.

The firmware level in this package is:


1.1 Minimum HMC Code Level

This section is intended to describe the "Minimum HMC Code Level" required by the System Firmware to complete the firmware installation process. When installing the System Firmware, the HMC level must be equal to or higher than the "Minimum HMC Code Level" before starting the system firmware update.  If the HMC managing the server targeted for the System Firmware update is lower than the "Minimum HMC Code Level" the firmware update will not proceed.

The Minimum HMC Code level for this firmware is:  HMC V7 R7.3.0 (PTF MH01255 or MH01256).

Although the Minimum HMC Code level for this firmware is listed above,  HMC level V7 R7.3.0 with PTF MH01279 (Service Pack 2), or higher is strongly suggested for this firmware level.

For information concerning HMC releases and the latest PTFs,  go to the following URL to access Fix Central.

For specific fix level information on key components of IBM Power Systems running the AIX, IBM i and Linux operating systems, we suggest using the Fix Level Recommendation Tool (FLRT):

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

2.0 Important Information

IPv6 Support and Limitations

IPv6 (Internet Protocol version 6) is supported in the System Management Services (SMS) in this level of system firmware. There are several limitations that should be considered.

When configuring a network interface card (NIC) for remote IPL, only the most recently configured protocol (IPv4 or IPv6) is retained. For example, if the network interface card was previously configured with IPv4 information and is now being configured with IPv6 information, the IPv4 configuration information is discarded.

A single network interface card may only be chosen once for the boot device list. In other words, the interface cannot be configured for the IPv6 protocol and for the IPv4 protocol at the same time.

Memory Considerations for Firmware Upgrades

Firmware Release Level upgrades and Service Pack updates may consume additional system memory.
Server firmware requires memory to support the logical partitions on the server. The amount of memory required by the server firmware varies according to several factors.
Factors influencing server firmware memory requirements include the following:
Generally, you can estimate the amount of memory required by server firmware to be approximately 8% of the system installed memory. The actual amount required will generally be less than 8%. However, there are some server models that require an absolute minimum amount of memory for server firmware, regardless of the previously mentioned considerations.

Downgrading firmware from any given release level to an earlier release level is not recommended.
If you feel that it is necessary to downgrade the firmware on your system to an earlier release level, please contact your next level of support.


3.0 Firmware Information and Description

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

Note: The concurrent levels of system firmware may, on occasion, contain fixes that are known as deferred. These deferred fixes can be installed concurrently, but will not be activated until the next IPL. Deferred fixes, if any, will be identified in the "Firmware Update Descriptions" table of this document. For deferred fixes within a service pack, only the fixes in the service pack which cannot be concurrently activated are deferred.

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.

System firmware file naming convention:

01ASXXX_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, 01AS330_067_045 and 01AS340_067_053 are different service packs.

An installation is disruptive if:

Example: Currently installed release is AS330, new release is AS340 Example: AS330_120_120 is disruptive, no matter what level of AS330 is currently
installed on the system Example: Currently installed service pack is AS330_120_120 and
new service pack is AS330_152_130

An installation is concurrent if:

Example: Currently installed service pack is AS330_126_120,
new service pack is AS330_143_120.

Note: The Checksum can be found by running the AIX sum command against the rpm file (only the first 5 digits are listed).
ie: sum 01AS730_066_066.rpm

System firmware changes that affect all systems

  • HIPER/Pervasive:  The initial value of the fault isolation register (FIR) for MULTICAST_TO_HFI_TIMEOUT was changed from recoverable attention to special attention to prevent multiple deconfigured Torrent modules across multiple CECs.
  • HIPER/Not pervasive:  A problem was fixed that caused a node to hang when booting, then terminate with SRC B1813450, B181C350, and B18187D9.
  • HIPER/Not pervasive:  On systems running the Advanced Energy Manager, a problem was fixed that caused the system to crash with SRC B114E504.
  • On systems using the Advanced Energy Manager (AEM) to run in Dynamic Power Save (DPS) mode, and with deconfigured processor cores, a problem was fixed that caused the processor voltages to be set incorrectly, which in turn caused the system to use more power than it should have been using.
  • A problem was fixed that caused the processor fabric bus to be guarded out when a time-of-day (TOD) clock failure occurred.  Only the TOD clock should be guarded out.
  • A problem was fixed that caused a node to be erroneously guarded out during power on.
  • The firmware was enhanced to increase the threshold for recoverable SRC B113E504 so that the processor core reporting the SRC is not guarded out.  This prevents unnecessary performance loss and the unnecessary replacement of processor modules.
  • On the System Management Services (SMS) remote IPL (RIPL) menus, a problem was caused the SMS menu to continue to show that an Ethernet device is configured for iSCSI, even though the user has changed it to BOOTP.
  • The firmware was enhanced to report an error to the operating system (OS) when a bad packet was sent from a host fabric interface (HFI) window.

System firmware changes that affect certain systems

  • On systems running host fabric interface (HFI) Ethernet, a problem was fixed that caused the TPC/IP boot parameters to be zeroed out, and the partition to fail to boot with HFI, when the partition was powered on.


4.0 How to Determine Currently Installed Firmware Level

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: AS730_123.

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: ASXXX_YYY_ZZZ

Where XXX = release level
