New features and functions: 

- DEFERRED:  Support for F/C 5802 (19" I/O drawer) and 5803 (24" I/O drawer).

Attention:  After this level of firmware is installed, the platform must be powered off, then powered on, before the 5802 or 5803 I/O drawer is added to the system. 

- DEFERRED:  Support for POWER VM Active Memory Sharing.

Attention:  After this level of firmware is installed, the platform must be powered off, then powered on to activate the POWER VM Active Memory Sharing function 

Attention:  If EM340_075 has been installed, and the new POWER VM Active Memory Sharing function has been activated, and you want to back-level the system firmware, the active memory sharing pool must be deactivated and deleted prior to back-leveling the system firmware.  IBM does not recommend back-leveling the system firmware.

System firmware changes that affect all systems:

• DEFERRED:  A problem was fixed that caused the advanced system management interface (ASMI) menus to become unresponsive, and the system to appear to hang, when a GX adapter slot reservation was attempted when the system was at service processor standby.
• A problem was fixed that caused the service processor diagnostics to report a "TOD (time-of-day) overflow" error, instead of an uncorrectable memory error, when failures occurred on memory DIMMs.
• A problem was fixed that prevented the system from powering on after the "reset service processor settings" or "reset all settings" option was selected in the advanced system management interface (ASMI) menus.
• The firmware was enhanced to improve the service processor's capability to recover from bad bits in the flash memory.  A predictive error, or an unrecoverable error, will be logged against the card that contains the system firmware if the number of correctable or uncorrectable errors exceeds the threshold.
• The callouts for SRC B181E6ED, which is logged when a system is booted with service processor redundancy disabled, were improved to indicate that redundancy was disabled rather than calling out a firmware failure.
• A problem was fixed that caused hardware to be deconfigured when the system encountered network errors, even though the SRCs were being logged as informational.
• 6A problem was fixed that caused the detailed data at the end of an "early power off warning type 5" AIX error log entry to be filled with invalid data instead of zeros.

• On systems with external drawers or towers, a problem was fixed that caused SRC xxxx6981, xxxx6982, or xxxx6985 to be logged.  When this problem occurred, some I/O slots might also be missing from the resource lists.
• On systems using on/off (temporary) memory capacity on demand (COD), the firmware was enhanced to improve memory COD's interaction with other tools (such as Inventory Scout in AIX), and to make the billing process easier.
• On systems with two hardware management consoles (HMCs), the firmware was enhanced so that the system will not restart and generate a service processor dump when the two HMCs are in the same subnet.  (This is an invalid configuration.)

• DEFERRED:  On systems running system firmware release EM340, a problem was fixed that caused the system to checkstop during the "hot add" of a GX I/O adapter card.

• A problem was fixed that caused a hot node repair operation to fail if 16GB huge pages were configured on the system.
• A problem was fixed that caused a concurrent node add or repair operation to fail if the operation immediately followed an upgrade of system firmware from EM330_xxx to EM340_039, then a concurrent installation of EH340_061.
• A problem was fixed that caused a partition reboot to hang at AIX progress code 0581, after the concurrent replacement of the I/O backplane in a model MMA drawer, when the partition owned resources in the drawer that was repaired.
• A problem was fixed that caused SRC B150D15E to be erroneously logged during a concurrent node addition or concurrent memory upgrade.

05/04/09

System firmware changes that affect all systems:

• DEFERRED:  The firmware was enhanced so that the system recovers gracefully from an I/O load time-out, rather than issuing a machine check, which crashes the system.
• A problem was fixed that caused the service processor diagnostics to report a "TOD (time-of-day) overflow" error, instead of an uncorrectable memory error, when failures occurred on memory DIMMs.
• 675457/FW210571 (picked up under feature 690994):  A problem was fixed that, in certain configurations, caused the removal of a host Ethernet adapter (HEA) port to fail when using a dynamic LPAR (DLPAR) operation.
• A problem was fixed that, under certain circumstances, prevented the operating system from recovering a PCI-E adapter on which a temporary enhanced error handling (EEH) error occurred.

• The firmware was enhanced so that a call home will be made if the hypervisor issues a "terminate immediate" interrupt. 
• A problem was fixed that prevented service processor and hypervisor error log entries from being reported to the operating system after a successful partition migration.  This problem only affected the partition that was migrated.

• A problem was fixed that prevented the system from powering on after the "reset to factory settings" option was selected in the advanced system management interface (ASMI) menus.
• A problem was fixed that caused the migration of an AIX or Linux partition to fail when firmware-assisted dump was enabled.  When this problem occurs, the partition becomes unresponsive on the target system, and the target system may have to be rebooted to recover.
• A problem was fixed that prevented the service processor from automatically booting from the permanent (or P side) if the temporary (or T side) of the firmware flash was corrupted.  When the problem occurred, the service processor stopped instead of booting from the P side.
• A problem was fixed that caused SRC B1818601 to be logged, and a service processor dump to be generated, at runtime.
• The firmware was enhanced to include processor card #1 in the list of field replaceable units (FRUs) that are called out if an I2C bus error occurs when accessing the processor backplane's vital product data (VPD).

• A problem was fixed that, under certain rarely occurring circumstances, might have caused dynamic LPAR (DLPAR) operations on memory to fail.
• A problem was fixed that prevented I/O hardware operations from completing before dynamic LPAR (DLPAR) operations were performed on memory.  This caused PCI bus errors, and multiple instances of SRC B7006971 to be logged.
• A problem was fixed in the hypervisor that, under certain rarely occurring circumstances, caused a system-level activation to fail.
• A problem was fixed that caused SRC B7006971 to be generated because the firmware was  incorrectly performing operations on PCI-Express I/O adapters during dynamic LPAR (DLPAR) operations on memory.
• A problem was fixed that might have caused a processor checkstop after a node repair or node add operation.
• A problem was fixed that caused the message "BA330000malloc error!" to be displayed on the operating system console after a partition migration, even though SRC BA330000 had not been logged.  When this problem occurred, the partition migration appeared to be successful.  However, a process within the partition was either hung or had failed, and in most cased the partition had to be rebooted to fully recover.
• The firmware was enhanced to improve the description and service actions that are logged with SRC BA210012.
• A problem was fixed that, under certain rare circumstances, prevented a partition migration from completing successfully if processors were removed from the partition being migrated prior to the migration using dynamic LPAR (DLPAR) operations.

06/09/08

System firmware changes that affect all systems:

• DEFERRED and HIPER: The processor initialization settings were changed to reduce the likelihood of a processor going into an error state and causing a checkstop or system crash.
• HIPER: A problem was fixed in the hypervisor that might cause a partition migration to fail.
• HIPER: A problem was fixed that caused large numbers of enhanced error handling (EEH) errors to be logged against the 4-port gigabit Ethernet adapter, F/C 5740, under certain circumstances.
• HIPER:  A problem was fixed that caused the firmware to erroneously log VPD errors against the processors. This prevented drawers from powering on.
• HIPER:  On system with a redundant service processor installed and enabled, a problem was fixed that caused a communications hang between the two service processors.  When this occurred, it triggered a reset/reload of the primary service processor, and the resulting fail-over to the secondary service processor failed in such a way that the system crashed and logged SRC B1813410.  Service processor dumps were also taken.
• HIPER:  On systems with redundant service processors installed and enabled, the firmware was enhanced so that if a failure occurs during a service processor failover, the firmware will attempt to reset/reload one of the service processors.  This may allow the system to recover and stay up instead of crashing.
• HIPER:  On systems with redundant service processors installed and enabled, a problem was fixed that caused the system to crash if a service processor failover occurred when the VPD files were being synchronized.
• The firmware was enhanced to improve the system memory error recovery.
• A problem was fixed that caused the /tmp directory on the service processor  to fill up, which results in an out-of-memory condition.  When this problem occurred, the service processor usually performed a reset/reload.  This is one possible cause of SRC B1817201 being logged.
• A problem was fixed that caused panel function 02 to fail when trying to set the "next IPL speed" or "next IPL side". 
• The firmware was enhanced so that serial port S1 is not automatically designated the local console, even if the console is not selected within 60 seconds of the system is first booted.  This enhancement allows the console to be selected again, if no selection was made on the previous boot, instead of defaulting to the S1 port.

05/06/08

New features and functions:

•  Support for the concurrent addition of a node (drawer) was added.
• Support for the "cold" repair of a node (repair with power off while other nodes are running) was added. 
• Support for IPv6 was added. For more information, see Section 2.1 Cautions, paragraph Concurrent Maintenance.
• Support for logical volumes bigger than 2 TB was added.
• Virtual switch support for virtual Ethernet devices was added.  This requires HMC V7 R3.3.0.0 with efix MH01102 to be running on the HMC. 

•  HIPER:  A problem was fixed that caused capacity-on-demand (COD) data to be retrieved in an unreadable format from the Anchor (VPD) card.
• HIPER:  A problem was fixed that caused enhanced error handling (EEH) to fail on certain I/O adapters.
• HIPER:  A problem was fixed that might cause the system to terminate while IPLing partitions soon after a system boot.  This problem might also have been seen if the partitions were set to "autostart".  This failure is typically seen on systems with a large amount of memory; SRC B181D138 is usually logged when this error occurs.
• DEFERRED:  A problem was fixed that caused the system to appear to hang with C10090B8 in the control (operator) panel during a slow mode boot.
• A problem was fixed that prevented the processor clock from being deconfigured with the fabric bus after a hardware error.
• A problem was fixed that caused the L2 deconfiguration option to be displayed advanced system management interface (ASMI) menus on systems on which it is not supported.
• A problem was fixed that caused the GX adapter slot reservation option to be displayed on the advanced system management interface (ASMI) menus on systems on which it is not supported.
• Fixes problem where wrong slot location was provided in message when no slot reservations were available for adding next Feature Code 1800 or 1802 adapter.
• A problem was fixed that caused the location code reported with enhanced error handling (EEH) errors on certain imbedded slots have a -Cx suffix instead of the correct -T# suffix for the underlying adapter.  This also impacted the HMC's System Planning tool.
• A problem was fixed that caused the Linux boot loader to lose its command line parameters (and fail to boot a Linux partition) during a reconfiguration reboot.
• A problem was fixed that caused the "iSCSI" and "network1" aliases to be created incorrectly in the SMS menus; this might have prevented the system or partition from booting from that device.
• A problem was fixed that caused this informational message to be erroneously sent to the operating system console: 

• A problem was fixed that caused the AIX command lsvpd to hang if it was executed during a partition migration.
• A problem was fixed that caused the system or partition to hang at the "Welcome to AIX" banner, following an iSCSI boot, during the installation of AIX.
• A problem was fixed that caused an iSCSI login to fail under certain circumstances.  When this failure occurred, the message sent to the console looked something like this:

• A problem was fixed that caused the location codes of devices attached to the integrated USB ports to have a duplicate port suffix.  For example, when this problem occurred, the location code of the device was shown as:

          instead of the correct location code, which is 

                              /usb-scsi@1  U787D.001.DQDGARW-P1-T2-L1
 

• Two translation issues were fixed.  The first one caused the string "No alias" to always be displayed on the iSCSI menus in SMS in English even though it should have been translated into the other languages that the SMS menus support.  The second one caused the NIC (network interface card) parameters such as the client IP address in the SMS ping menu to be displayed with message strings in English; these should have been translated as well.
• A problem was fixed that caused the SMS menus to drop into the open firmware prompt with the message "DEFAULT CATCH!" when the ping test failed.
• A problem was fixed that prevented the operating system from setting the boot device list in NVRAM.
• A problem was fixed that caused approximately 20-25 occurrences of informational SRC B7005300 to be logged during every IPL, which was filling up the error logs.
• A problem was fixed that prevented the "100 Mbps/full duplex" setting for the HEA 1 Gbps ports from being implemented from the HMC.  When this occurred, there was no error message on the HMC, but the setting never took effect.
• A problem was fixed that caused the MAC addresses displayed on the HMC, in the HEA logical port information for the second port group, to show invalid addresses.
• A problem was fixed that caused a service processor dump to be generated with SRC B181EF88 when the advanced system management interface (ASMI) client was closed abruptly, or a network failure disconnected the client and the ASMI.
• Enhancements were made to improve  the field replaceable unit (FRU) isolation for phase-locked loop (PLL) clock failures on multi-CEC drawer system.  SRCs B114F6D2, B114F6C1, B113F6C1, B157F12E, B18187EF, and B158E500 were typically seen with this type of failure.
• Enhancements were made to the error analysis firmware to provide better FRU callouts for certain types of processor fabric bus failures.  SRCs B114E504, B114B2DF, and B181B10B were typically seen with this type of failure.
• Enhancements were made to the firmware to improve the reliability of memory DIMMs.
• A change was made to the firmware such that predictive SRCs B18138B0, B1813862, or B1813882 are now logged as informational.

• On system using the EnergyScale^(TM) technology, enhancements were made to include status, log, and error information about the Power Save mode in the service processor error logs.
• On systems with redundant service processors enabled, a problem was fixed that caused the "restore factory configuration" function on the Advanced System Management Interface (ASMI) to fail.
• On systems with 7314-G30 drawers attached, a problem was fixed that caused the InfiniBand I/O device to drop packets, which resulted in an unrecoverable error.
• On systems with 7314-G30 drawers attached, a problem was fixed that caused the drawer to fail when performing concurrent maintenance on the associated InfiniBand loop.
• On systems with 7314-G30 drawers attached, a problem was fixed that caused the partition to become unresponsive when an InfiniBand cable in a redundantly-cabled loop was disconnected.

Fixes that affect all model MMA systems:

• HIPER:  A problem was fixed that caused a concurrent firmware installation to hang with SRC BA00E840 being logged.  This problem may also cause a partition migration to hang, under certain circumstances, with the same SRC, BA00E840, being logged.  This SRC will be logged when this level of firmware is installed and will generate a call home; it should be ignored.  It will not be logged during subsequent installations.
• HIPER:  On systems with redundant service processors installed and enabled, a problem was fixed that caused the system to crash if a service processor failover occurred when the VPD files were being synchronized.
• HIPER:  On systems with redundant service processors installed and enabled, the firmware was enhanced so that if a failure occurs during a service processor failover, the firmware will attempt to reset/reload one of the service processors.  This may allow the system to recover and stay up instead of crashing.
• HIPER:  A problem was fixed that caused the firmware to erroneously log VPD errors against the processors. This prevented drawers from powering on.

03/03/08

Fixes that affect all model MMA systems:

• DEFERRED:  A problem was fixed that caused a system crash (with SRC B131E504) by changing the initialization settings of the I/O control hardware.
• A problem was fixed that could cause the hypervisor to hang after a reset/reload of the service processor.
• A problem was fixed that, under certain circumstances, caused the InfiniBand adapter to stop responding to InfiniBand requests.
• A problem was fixed that caused SRC B1813014 to be logged after a successful system firmware installation.  This SRC will be logged when this level of firmware is installed and will generate a call home; it should be ignored.  It will not be logged during subsequent installations.
• The FRU list was changed so that clock card failures in a multi-drawer system will be easier to debug and require fewer parts to fix.
• A problem was fixed that caused the service processor to get stuck in a reset/reload loop, which prevented the system from booting to standby.

System firmware changes that affect certain model MMA systems:

• On systems with redundant service processors enabled, a problem was fixed that could cause a significant increase in system boot time.
• On systems with two service processors installed and with redundancy disabled, a problem was fixed that caused the secondary service processor to go into the dump state, and remain in the dump state, after a platform dump.
• On systems with redundant service processors, SRCs B1813833 and B1813834, which were being logged intermittently after a side-switch IPL, were changed to informational.
• On systems with a 1519-100 tower attached, a problem was fixed that caused the location code of a connector on the integrated virtual IOP to be displayed as Un-SE1-SE1-T1 instead of Un-SE1-T1.
• On systems with 7134-G30 I/O drawers attached in certain cabling configurations, a problem was fixed that prevented the I/O port labels from being displayed for the port location codes on the hardware topology screens.

System firmware changes that affect all systems:

• DEFERRED and HIPER:  The system initialization settings were changed to reduce the likelihood of a system crash under certain circumstances.
• HIPER:  A problem was fixed that caused a system to fail to reboot after a B1xxE504 SRC was logged, due to a processor interconnection bus failure.  The same SRC, B1xxE504, was logged when the reboot failed.
• A problem was fixed that, under certain rarely occurring circumstances, caused the system to crash if an L2 or L3 cache failure is not discovered and repaired when it initially occurs.
• The firmware was enhanced so that the contents of /tmp are included when a service processor dump is taken.
• A problem was fixed that, in certain configurations, caused the removal of a host Ethernet adapter (HEA) port using a dynamic LPAR (DLPAR) operation to fail.
• A problem was fixed that, under certain rare circumstances, caused the hypervisor to crash when it was booting with and SRC B6000103 being logged.
• A problem was fixed that, under certain circumstances, prevented the operating system from recovering a PIE adapter on which a temporary enhanced error handling (EEH) error occurred. 
• A problem was fixed that prevented service processor and hypervisor error log entries from being reported to the operating system after a successful partition migration.  This problem only affected the partition that was migrated.
• The firmware was enhanced so that a call home will be made if the hypervisor issues a "terminate immediate" interrupt.

•  In systems with clustered processors, various problems were fixed in the InfiniBand interconnection networks.
• On systems with a host Ethernet adapter (HEA) or host channel adapter (HCA) assigned to a Linux partition, a problem was fixed that prevented the partition from booting if 512 GB, 1 TB, or 1.5 TB of memory was assigned to the partition.  When this problem occurred, SRC B700F105 was logged.

System firmware changes that affect all systems:

• DEFERRED and HIPER: The processor initialization settings were changed to reduce the likelihood of a processor going into an error state and causing a checkstop or system crash.
• HIPER: A problem was fixed that caused large numbers of enhanced error handling (EEH) errors to be logged against the 4-port gigabit Ethernet adapter, F/C 5740, under certain circumstances.
• DEFERRED:  A problem was fixed that  caused informational SRCs B181B964 and B150D134 to be logged multiple times, and fill the service processor error log, during normal operation of the system.
• DEFERRED:  The firmware was enhanced so that if an L3 cache controller gets deconfigured at runtime, the associated processor cores will also be deconfigured.  This prevents the system from going into an error state and causing a checkstop or system crash.
• A problem was fixed that caused the /tmp directory on the service processor  to fill up, which results in an out-of-memory condition.  When this problem occurred, the service processor usually performed a reset/reload.  This is one possible cause of SRC B1817201 being logged.
• Enhancements were made to improve  the field replaceable unit (FRU) isolation for phase-locked loop (PLL) clock failures on multi-CEC drawer system.  SRCs B114F6D2, B114F6C1, B113F6C1, B157F12E, B18187EF, and B158E500 were typically seen with this type of failure.
• A problem was fixed that caused SRC B1813014 to be erroneously generated when a new level of system firmware was installed on the managed system.
• A problem was fixed that caused SRC B7006971 to be erroneously generated during dynamic LPAR (DLPAR) operations on memory.
• A problem was fixed that caused an "HTML viewer error", followed by the message "Cannot complete service action for reference code 'xxxxyyyy' "  to occur in Service Focal Point on the HMC when trying to perform the service actions for certain SRCs.
• A problem was fixed in partition firmware that could cause a partition running AIX to crash under certain circumstances.

• On a partition running Linux, a problem was fixed that might cause the hypervisor to erroneously deconfigure a processor core.
• On partitions with a large number of hard disks attached to fibre channel adapters, a problem was fixed that might cause SRC BA210003 to be erroneously generated when the partition is booting.  The partition might or might not boot when this error occurs.
• On systems with 7314-G30 drawers attached, a problem was fixed that caused the port labels to be missing on the hardware topology screens with certain cable configurations.
• On systems with 7314-G30 drawers attached, a problem was fixed that caused the partition to become unresponsive when an InfiniBand cable in a redundantly-cabled loop was disconnected.
• On systems with 7314-G30 drawers attached, a problem was fixed that might have caused some I/O slots in the drawers not to be configured when the system was booted.

02/11/2008

Fixes that affect all model MMA systems:

• HIPER:  A problem was fixed that caused some functions that perform hardware operations during runtime to generate temporary extended error handling (EEH) errors.
• DEFERRED:  A problem was fixed that caused a system crash (with SRC B131E504) by changing the initialization settings of the I/O control hardware.  Note: This fix is not in the EM320_031_031 level listed above;  it is included in the EM320_040_031 level.
• A problem was fixed that prevented a system from recovering after SRC B1xxB9xx was logged.
• A problem was fixed that caused a firmware installation to fail with SRC B1813028.
• A problem was fixed that caused SRC B1818A10 to be erroneously logged during a disruptive firmware installation.
• A problem was fixed that, under certain circumstances, caused the buttons on the control (operator) panel to be inoperative.
• A problem was fixed that prevented the system planning tool from deploying a sysplan with certain HEA MCS values.
• A problem was fixed that caused SRC B1813108 to be erroneously logged during system boot. 
• A problem was fixed that, under certain circumstances, caused the InfiniBand adapter to stop responding to InfiniBand requests.
• A problem was fixed that caused the error "MSGVIOSE0300E002-0154 There is insufficient memory available for firmware" to be logged on the HMC.

•  On model MMA systems with multiple drawers, a problem was fixed that prevented the pin-hole reset switch on the control (operator) panel from resetting the system.
• On model MMA system with an uninterruptible power supply (UPS) attached, a problem was fixed the prevented the UPS from notifying the operating system that a utility failure or low battery condition had occurred. 
• On systems with at least 3 or more licensed processors and 2 or more unlicensed processors, a problem was fixed that caused the system boot to be slower than normal, or to hang with SRC C700406E.
• On model MMA system with 7314-G30 I/O expansion drawers attached, problems were fixed that caused the wrong FRUs to be called out with SRC B70069ED, and caused the hypervisor to loop if certain invalid cabling configurations are encountered.
• On model MMA systems with a large number of I/O towers attached, a problem was fixed that caused the HMC to go to the incomplete state when an additional tower was added to a loop.

11/19/07

• HIPER:  A problem was fixed that caused a time-out in a hardware device driver.  This time-out must include both SRCs B181B920 and B181D147.  Other SRCs may be present including, but not limited to, B1xxB9xx, B1xxE504, and B150D141.  Occasionally the system crashes.  If B181B920 and B181D147 SRCs are logged, check for any resources that were deconfigured at the time of these errors and reconfigure them using the ASMI menus.  No hardware should be replaced.  To recover from this error condition, the service processor must be reset by removing,  then reapplying, the managed system's power.
• DEFERRED:  On multi-drawer model MMA systems, a problem found in testing was fixed which when the L3 cache was disabled,  under very unique (and rare) circumstances may result in data being overwritten in the cache and the system to crash.  Although the exposure to this issue is very low, and there have been no reported problems from the field, the system impact if this occurred would be high.  Product Engineering recommends that you schedule time to install this deferred fix at you earliest convenience.

9/14/07

Additional features and functions:

• Added support for 9406-MMA.

• HIPER:  A problem was fixed that caused the system to crash with SRC B170E450.
• HIPER:  A problem was fixed that, in rare circumstances, could cause the system to hang due to the improper handling of certain exceptions.
• HIPER:  A problem was fixed that prevented the operating system from being notified of certain EPOW conditions that could lead to the system or partition being shut down, with the possible loss of data.  These EPOW conditions included the ambient temperature being too high, the loss of utility power (with or without UPS backup), and a user-initiated power off using the white power button or the HMC.
• A problem was fixed that could cause a firmware installation from the HMC to fail with SRC E302F85C on the HMC, and SRC B1813088, B1818A0F, or B1813011 logged in the service processor error log.
• A change was made so that if a failure occurs during a memory-preserving reboot, the system continues to reboot rather than remaining in the termination (powered off) state.
• A problem was fixed that caused EEH (enhanced error handling) errors to be erroneously logged against certain I/O adapters.
• A problem was fixed that prevented "linked" resources that had been guarded out from being reconfigured during the next reboot after a service action on one of the guarded parts.
• A problem was fixed that, after the backplane was replaced in a 7314-G30 I/O drawer, prevented the partition that owned the drawer from seeing those resources. 
• A problem was fixed that caused the serial connection to a partition to be lost.  When this occurred, SRCs B181D307, B200E0AA, and/or B200813A were generated by the service processor and the hypervisor.
• A problem was fixed in partition firmware that, in some circumstances, prevented a CD-ROM or tape device from being in the default service mode boot list, even if one was present in the system.
• A problem was fixed that caused the HMC to go to the incomplete state, and SRC B182953C to be logged in the service processor error log every five minutes or so, when the managed system was booted.
• A problem was fixed that caused the system to intermittently fail to configure devices attached to the integrated USB port when booting.
• A problem was fixed that might have caused erroneous callouts if a problem was found with certain levels of memory controller chips.
• A problem was fixed that caused the system to call home and reboot instead of allowing the failing part (a memory controller or DIMM) to be deconfigured by PRD (processor runtime diagnostics). 

In addition to the fixes described above, this service pack also contains a fix for a low probability problem and content intended for newly-manufactured systems, or enhancements to system internal interfaces, which is not required for systems already in production use.   This content will not be activated on systems that install this service pack concurrently.  Even though this content is not required for systems which are already installed and in use, a disruptive installation of this service pack or a re-IPL after installing it will cause this content to become active.  It is not necessary to plan a window for re-IPL the system the activate this content.
