1.0 Firmware Change History

Code Level	Description
BP235_157	GA6 Service Pack 1 (for use with 9118-575 ONLY): Fixes for problems related to concurrent and non-concurrent I/O drawer adds
BP230_155	GA5 Service Pack 4: A new System Reference Code will now be reported if the firmware level on each pair of BPCs is mismatched for a time period of more than 1 hour. The purpose is to alert the user of this situation in cases where the firmware update process did not complete on both BPCs or where a BPC has been replaced but the firmware update of the new BPC was not performed.
BP235_156	GA6: General Availability Support for the 9119-590/595 and 9406-595 redundant Service Processors with dynamic failover
BP230_145	GA5 Service Pack 3: Increased the error log maximum size to prevent data from being truncated
BP230_143	GA5 Service Pack 2: Fix for false 11008720 & 1100821 errors during run time Fix for intermittent unowned I/O drawer condition after frame initialization Fix for false 14001302 error during boot up Fix for problem causing error message "no redundant hardware available" Fix for BPC dump during Power code load operation, causing HMC to display error ACT01724 Fix for BPC hanging with return code 7 sent to HMC. Power code load operation fails
BP230_131	GA5 Service Pack 1
BP230_125	GA5: pSeries High Performance Switch General Availability

2.0 General Information

This package provides updated Power Subsystem Firmware for use on the following systems only:

pSeries 9118-575

Do not use on any other systems. The package contains downloadable Firmware for some or all of the following power subsystem components: BPC (Bulk Power Controller), BPR (Bulk Power Regulator), DCA (Distributed Converter Assembly and MDA (Motor Drive Assembly).

2.0.0 Where to Obtain the Firmware

This firmware can be found at the following locations:

From the IBM Microcode downloads Website as individual files (http://www14.software.ibm.com/webapp/set2/firmware/gjsn
),
- Select one of the following from the Download microcode by machine type and model drop-down menu:
From the IBM Microcode update files on CD-ROM Website as a CD-ROM image ( http://www14.software.ibm.com/webapp/set2/firmware/gjsn?mode=10&page=cdrom.html ) :
Use this image file in conjunction with a computer that is capable of creating CD-ROMs.
NOTE: This CD-ROM image also contains System Firmware

2.0.1 How to Load the Firmware

IMPORTANT NOTE:
Before attempting to load this firmware please ensure that your HMC (Hardware Management Console) software has been upgraded to the appropriate version. HMC version information can be found at: https://www14.software.ibm.com/webapp/set2/sas/f/hmc/power5/tips/matrix.html

The instructions regarding how to query, obtain, install and remove firmware levels can be found on the following IBM Infocenter Page: Getting server firmware and power subsystem firmware fixes and upgrades

2.1 Cautions and Important Notes

Never Turn Off the UEPO switch (red switch) During the Power Subsystem Firmware Update Process -- the update will fail, and the process must be repeated. Also, the power component being loaded could be permanently disabled.
Never Log Off of the HMC During the Power Subsystem Firmware Update Process -- the update will fail, and the process must be repeated.
Service any existing problems with the Power Subsystem prior to attempting to load Power Subsystem Firmware from the HMC. Outstanding problems can cause the Power Subsystem to be in an N-mode power state (which means there has been a loss of redundancy) and can prevent the HMC from being able to load the Power Subsystem Firmware.
