• On systems or partitions loading Red Hat Linux, a problem was fixed in the System Management Services (SMS) firmware that caused the TFTP transfer of a file with a name longer than 63 characters to fail.

This level was made available via the Supplemental Firmware website ONLY. 

• A problem was fixed that could cause an HMC VTERM, or System Port-attached ASCII terminal, to stop responding after an application output a large number of characters in a short period of time.
  

This level is a disruptive update from any SF240_xxx firmware level.   The system should be powered off before installing this level of system firmware.  If this level is installed when the system is running, the CECs will be rebooted, causing all partitions to be terminated, and a reboot will be required.

ATTENTION: Systems at Firmware Level SF240_371_201:

• A problem was fixed that caused an out-of-memory condition to occur on the service processor, and SRC B1551360 to be logged. 

• HIPER:  On model 575 and 595 systems, a problem was fixed that could cause the service processor in the system and the service processor in the bulk power controller (BPC) to have duplicate IP addresses.  This caused the HMC to lose communication with the service processor in the system, and the system to crash.

• The firmware was enhanced to improve the failure isolation and FRU callout when certain hardware failures that call out the clock card occurred.
• On model 575 and 595 systems, a problem was fixed that could cause the service processor in the system and the service processor in the bulk power controller (BPC) to have duplicate IP addresses.  This caused the HMC to lose communication with the service processor in the system, and the system to crash.
• On systems and partitions running Linux, a problem was fixed that prevented certain types of I/O adapter (IOA) errors from being detected.  When these errors were not detected, the appropriate enhanced error handling (EEH) errors were not generated.
• On i5 partitions using IOP-based I/O adapters which are configured to use i5 clustering (SAN), a problem was fixed that caused the failover of an I/O drawer or tower, to a system which previously owned the drawer or tower, to fail.

System firmware changes that affect all p5 and i5 systems:

•  HIPER:  A problem was fixed that, under some circumstances during DLPAR (dynamic LPAR) operations or partition boot of a PCI adapter, caused another PCI adapter that shared the same bus (but was not necessarily in the same partition) to enter the freeze state and adapters on the same bus would become Defined.  When this problem occurred, SRCs were logged that indicated a problem with an adapter or bus (BxxxA6D9, BA180008, BA180009, and/or BA180010 for example). 
• HIPER:  A problem was fixed that caused platform system dumps to be incomplete in firmware level SF240_332.

• HIPER:  A problem was fixed in open firmware that caused a Linux kernel fault because a list pointer was corrupted during boot.
• A problem was fixed that could cause the system to boot slowly, or hang, before the operating system got started.  If this occurred, the service processor might have rebooted or generated a dump.

• A problem was fixed that caused a partition to fail to boot with SRC B2001230 (with word 13 = 000000BF and word 14 = 00000002) after the DLPAR removal of a PCI I/O adapter from that partition.   If a partition has failed to boot with this SRC, the platform must be rebooted after this level of firmware is installed to clear the error condition and allow the partition to boot.
• The firmware was updated to add the system VPD card and service processor to the Advanced System Management Interface (ASMI) deconfiguration menu under the celogin. 
• On systems running system firmware SF240, a problem was fixed that caused the system to stop booting and log SRC B1xxB0BF.

• A message was added to the "Configure I/O Enclosure" menu on the ASMI (advanced system management interface) asking the user to wait for the operation to be completed, because submitting multiple requests can cause the service processor to crash.

• HIPER:  A problem was fixed that caused the service processor's /tmp filesystem to became full.  This caused failures with various symptoms, the most common one being system termination.   This problem also could cause a concurrent firmware installation to fail with SRCs B1818A03, B1818A0E, B1818A08 and B1818A05.
• HIPER:  On models 570, 590 and 595, the firmware was changed so that SRCs B150E678, B150E679, B150E67B, B150E67C, B150E67D, B150E67E and B150E67F have been made informational events; they no longer generate a call home.  In addition, the algorithm that is used to determine when to label SRCs B150E675, B150E676 and B150E67A "serviceable events" has been altered; the threshold is now more than 15 errors on a multiplexer card (also known as a "mux" card) have to be logged in less than 24 hours. 
• HIPER:  A problem was fixed that caused SRC B155B086 to be logged, and a call home to be made, when the service processor was reset when the CEC was powered on.

• B150E675:  Marked "informational" until the threshold is exceeded, then marked "predictive".
• B150E676:  Marked "predictive" if the mux in both node 0 (or drawer 0) and node 1 (or drawer 1) fails to ping; informational in all other cases.
• B150E67A:  Informational until the threshold is exceeded, then marked "predictive, degraded".
• B150E678, B150E679, B150E67B, B150E67C, B150E67D, B150E67E and  B150E67F:  Informational

• On models 590 and 595, the firmware was changed so that the JMUX is called out first in the FRU list for SRC B1xxF131. 
• A problem was fixed that prevented the HMC from reestablishing a connection to the managed system's service processor when the network between the two was fixed after a long outage.
• A problem was fixed that caused the HMC to be in the "incomplete" state after a service processor reset/reload.
• A problem was fixed that prevented the HMC from correctly opening a VTERM.
• A problem was fixed that caused the managed system to crash with SRC B181EF88 being logged, and a service processor dump being generated.
• On systems with a redundant service processor, a problem was fixed that added approximately 10 minutes to the time it took the system to reboot.
• On systems with a redundant service processor, a problem was fixed that caused an unrecoverable error with SRC B1818610 during a firmware installation by the HMC.  This also prevents the new level of firmware from being activated. 
•  On systems with a redundant service processor, a problem was fixed that caused the redundancy status panel on the HMC to be blank when the primary service processor had lost communication with the secondary, but the secondary service processor was still able to communicate with the primary.
• On systems with a redundant service processor, a problem was fixed that caused the system to crash (with SRC B18187E3 being logged) when an administrative failover to the secondary service processor was initiated and Ethernet port 0 on the service processors was not available.
• On systems with a redundant service processor, a problem was fixed that caused the system to crash (with SRC B1818600 being logged), followed by a service processor failover.
•  On systems with a redundant service processor, a problem was fixed that caused the ASMI hardware configuration/deconfiguration menus to display "Invalid" for the state of the secondary service processor. 

• On model 55A, 52A, and 285 systems with a graphics adapter, a problem was fixed that caused the system to hang (progress code D200B077 in the control panel) when it rebooted the first time after AIX was installed.

In addition to the fixes described above, this service pack also has 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 to re-IPL the system to activate this content.

03/07/07

 New features/functions: 

• On systems with a redundant service processor, a function was added so that a call home with SRC B181601E is made when the system is booted with failover disabled.  ATTENTION:  On systems with redundant service processors that are being upgraded from an SF235 release level to SF240_298 or higher, SRC B181601E will be posted during the firmware upgrade process.  In this case only, the SRC B181601E can be ignored. 

• HIPER:  On systems with a redundant service processor, a problem was fixed that caused service processor failover to be erroneously disabled after a CEC deconfiguration action.

• HIPER:  For systems in an Opticonnect cluster with firmware levels prior to SF240_284 installed, a problem was fixed that caused a system to terminate with SRC B182E500.  Unlike the fix provided for this problem in SF240_284, this fix can be concurrently activated. 
• A problem was fixed that caused SRC 10009118 to be posted erroneously on systems in an Opticonnect cluster.
• A problem was fixed that caused systems in an Opticonnect cluster to terminate with SRC B700F103 during the reset of an HSL connection.

System firmware changes that affect systems using HSL Opticonnect:

• A problem was fixed that caused a system in an Opticonnect cluster to crash with SRC B182E500 when partitions were activated.
• A problem was fixed that might have caused partitions running on systems in an Opticonnect loop to become unresponsive.
• A problem was fixed that might have caused HSL Opticonnect connections between partitions in a cluster (which has three platforms in a common HSL ring) to fail when one of the platforms is rebooted.
• A problem was fixed that prevented errors on PCI buses (connected by an HSL Opticonnect loop) from being handled properly; unpredictable results occurred in active partitions that were using the failing hardware. 
• A problem was fixed that caused the HSL loops to fail, when the loop had switchable towers, and one of the servers on the loop was booted. 
• A problem was fixed that prevented the hypervisor from correctly moving an IOP-less adapter if an I-ASP failover occurred.
• A problem was fixed that caused the ownership of the IOP to be out of sync after an I-ASP failover.
• A problem was fixed that caused the adapters that were not involved in an I-ASP failover to be missing, because they were not fully processed. The symptom depends on the adapters that were not fully processed.

• HIPER:  On model 575, 590, and 595 systems, a problem was fixed that caused a memory failure with SRC B123E500 after the concurrent repair of a CEC DCA. 
•  In a large cluster of systems, a problem was fixed that caused the clustered system manager to receive the same IP address for multiple managed systems - causing no connect or incomplete status to be displayed on the HMC for those managed systems.
• In a large cluster of systems, a problem was fixed that caused the AIX  DHCP server to assign a new IP address to a service processor, even though the service processor was already using its old (valid) IP address. When this problem occurs, the HMCs start seeing different frames and/or CECs in the list of managed systems from the ones they normally see.
• On model 590 and 595 systems, this firmware level fixes a problem that prevented capacity upgrade on demand (CUoD) DDR2 memory from being activated properly when it was installed in a system that had been running with non-CUoD DDR2 memory.  The problem is usually seen as having less memory activated than expected, possibly not enough to activate a partition.  To correct this problem if it currently exists on the system, after installing this firmware level the system must be rebooted (to recollect the memory configuration data) and new activation code for the CUoD memory have to be entered.  SF240_284 becomes the new minimum firmware level required for FCs 4500, 4501 and 4502 CUoD DDR2 memory cards. 
• On a partition booting i5/OS, a problem was fixed that prevented the partition from booting if the partition had a large amount of memory (greater than approximately 200 GB) allocated to it. 
• On systems that are partitioned, a problem was fixed that caused a partition with more than 128 MB of memory, and with a logical memory block (LMB) size of 16 MB, to fail to boot.
• A problem was fixed that prevented a partition with huge pages (with a page size of 16 GB) from completing the power-off process.
• A problem was fixed that prevented some partitions from being reactivated after a short power outage caused them to be deactivated.
• A problem was fixed that caused dynamic logical partitioning (DLPAR) operations to fail (with SRC HSCL025A:  "Service processor lock failed.") even though there appeared to be no other activity that would cause them to fail. 
• A problem was fixed that caused a switchable tower to fail to recover after a tower switch operation.
• A problem was fixed that caused the HMC to go to the incomplete state when utilization data was requested from the managed system.
• A problem was fixed that caused the HMC to erroneously go to the incomplete state with SRC B7000602. 
• A problem was fixed that was delaying the reporting of some platform errors to the partitions running on the system.
• A problem was fixed that caused an IOP-less i5/OS partition with a large amount of memory and a small logical memory block (LMB) size to fail to boot.
• A problem was fixed that prevented the enclosure LED from being turned on when the FRU identify LED on one of the components in the enclosure was turned on.
• On systems with a redundant service processor, a problem was fixed that caused SRC B181B013 to be erroneously generated when the system firmware was upgraded from SF235_xxx to SF240_xxx.
• On systems with a redundant service processor, a problem was fixed that caused a duplicate IP address to be assigned to the eth0 port of the service processors.  This problem is most likely seen at first install of the machine, with an "invalid readiness" connection status shown on the HMC and an SRC B1xx3598 posted n the error log.
• On systems with a redundant service processor, a problem was fixed that caused an entry in the service processor error log that erroneously indicated that the secondary service processor had been guarded out.
• On systems with a redundant service processor, a problem was fixed that caused the secondary service processor to reset/reload after several months of run time (with SRC B1817201), due to an out-of-memory condition.
• On systems with a redundant service processor, a problem was fixed that caused SRC B1815008 to be erroneously logged in the secondary service processor's error log.
• On systems with a redundant service processor, a problem was fixed that caused the wrong service processor to be called out in the error log entry for SRC B7006990.
• On systems with a redundant service processor, a problem was fixed that caused the connection state to toggle between "Incomplete", "No Connection" and "Already Connected".
• On systems with a redundant service processor, a problem was fixed that could have allowed the firmware to initiate a service processor failover, even though the secondary service processor was not ready for the failover.

• On model 520, 52A, 550 and 55A systems, a problem was fixed that caused the second power supply to be called out as defective if power was applied to it after the system had started to power on.  If this error condition is already present on the system, the power supply will have to be reseated to clear the error.
• A problem was fixed that would have caused the memory DIMMs to be replaced prematurely if correctable errors start to occur.  This applies to model 561 systems with processor features code 7295 or 7781 installed, and model 570 systems with processor feature code 7782 installed.
• A problem was fixed that might have caused the wrong memory DIMM to be called out if a memory failure occurs.  This applies to model 561 systems with processor features code 7295 or 7781 installed, and model 570 systems with processor feature code 7782 installed.

04/18/06

Fixes that were deferred in earlier levels but are concurrent in this level: 

In firmware levels SF235_180  and SF235_185, there were two fixes that were deferred: 

1.  A fix that affected all p5, i5, and OpenPower systems: 

HIPER:  An incorrect initialization setting in the shared memory interface  (SMI) may cause a system checkstop, which could result in a system or partition crash. This is also known as the "SMI parity error" issue. 

In SF235_206 and higher service packs, this fix is CONCURRENT. 

2.  A fix that affected all p5, i5, and OpenPower systems: 

HIPER:  The initialization settings of the memory buffers were changed to fix an incorrect timeout setting in the non-cacheable unit (NCU).  The current settings may cause a system checkstop, which could result in a system and partition crash.  This is known as the "EMQ hang" problem. 

In SF235_206 and higher service packs, this fix is CONCURRENT.  Also in this release of the fix, the recovery time for the EMQ hang was improved to benefit HACMP configurations. 

System firmware changes that affect all p5 and i5 systems:

• HIPER:  A problem was fixed that caused the system to interpret a machine condition as requiring special attention handling, where no such special attention existed.  This could result in a system checkstop.  This problem is also know as the "Master Attention Alone" condition.
• HIPER:   A problem was fixed that might prevent the system from completing memory bit steering on DDR1 DIMMs during runtime.  In this scenario, the system posts an SRC of B120E500, which informs the user to IPL the system to complete the memory bit steering operation.  This fix allows the system to complete the memory bit steering during runtime (with no SRC being posted), and no reboot is required.  (If memory runs out of spare bits to use for steering, the system will post SRC B123E500 as a predictive error, with word 8=xxxxxx8A.)
• DEFERRED and HIPER:  Additional hardware initialization settings were changed to prevent system hangs with B7xx406E reference code. 
• DEFERRED:  A problem was fixed that caused a dump to stop before completion after a hardware failure with error code B1xxF22A.
• DEFERRED:  A problem was fixed that caused the system to terminate with an error code of B182901D.
• A problem was fixed that caused the service processor to perform a reset/reload too frequently, which caused too many dump files to be generated.
• A problem was fixed that was causing SRC B1xxE500 (with SRC word 8 equal to DD02) when processor runtime diagnostics were called during a dump.
• A problem was fixed that caused a BA180010 error to be logged when a PCI-X DDR slot was empty.
• A problem was fixed that caused error codes 11001D60 and 11001D63 to be erroneously generated when powering down the system.
• A problem was fixed that kept an already-connected uninterruptible power supply (UPS) from being detected correctly after the service processor performed a reset/reload operation. 
• A problem was fixed that caused the system to fail to boot if the white power button was pressed within 10 seconds after reaching standby, but before C1802000 was posted on the control (operator) panel.
• A problem was fixed that caused error code B157F22A to be posted after a main store dump.
• A problem was fixed that prevented informational errors in the advanced system management (ASM) error logs from being seen by the admin user.
• The firmware was changed to insure that error log entries related to ambient temperature problems (error codes such as 11007201, 11007203, and 11007205, for example) are sent up to the operating system. 
• A problem was fixed that was preventing systems and partitions with multiple fiber channel adapters from booting.
• A problem was fixed that caused a reset/reload to fail with error code B181D13C  when a certain type of hardware attention was being handled.

• DEFERRED and HIPER:  A potential server checkstop issue exists in clusters using p5 models p575, p590, and p595, when these models are used to execute compute-intensive applications tuned with the November Power5 Fortran compiler.  Clusters executing applications that are compiled for optimal performance by utilizing the software pre-fetch function are exposed to a server checkstop (B1xxE500). Hardware initialization settings were changed to fix this problem and  the performance tools modified to take these new settings into account. 
• DEFERRED and HIPER:  An initialization problem was fixed that was causing the high-performance switch (HPS) network adapter to hit the adapter error threshold during run-time.
• HIPER:  A problem was fixed that caused model 575 nodes to fail to boot with SRC B1817201.
• HIPER:  On systems with a high performance switch (HPS) network adapter installed, a problem was fixed that caused a checkstop when memory was moved from a partition that did not own an HPS network adapter.
• HIPER:  A problem was fixed that was causing the power control code to time out when querying the vital product data (VPD) on large system configurations.
• HIPER:  In a system with a redundant service processor, a problem was fixed that caused erroneous registry errors with error code B1818A09 to be generated intermittently.
• HIPER:  In a system with a redundant service processor, a problem was fixed that caused runtime fail-over to the secondary service processor to fail.
• HIPER:  In a system with a redundant service processor, a problem was fixed that caused 11001Dxx error codes to be erroneously logged after a failover to the secondary service processor.
• HIPER:  In a system with a redundant service processor, a problem was fixed that caused the system to fail to boot, and one of the service processors to become deconfigured.
• HIPER:  In a system with a redundant service processor, a problem was fixed that caused the corruption of registry values on the primary service processor.  This registry corruption was evidenced by the fact that the hypervisor reported the amount of configurable memory incorrectly.
• In a system with a redundant service processor, a problem was fixed that caused a firmware installation to fail with multiple occurrences of error code B1818A0E.
• The firmware was enhanced so that control (operator) panel function 30 displays the secondary service processor's IP address as well as the primary service processor's IP address.
• In a system with a redundant service processor, a problem was fixed that was causing error code B17CE433 to be erroneously generated after an administrative fail-over.
• A problem was fixed that caused error code HSCL1400 to be generated when a redundant service processor was installed with firmware release SF230 or earlier.
• In a system with a redundant service processor, a problem was fixed that was causing the secondary service processor to fail after too many write operations into the flash memory.
• In a system with a redundant service processor, a problem was fixed that was causing the system to reboot continuously while the secondary service processor was attempting to mount a file system.
• On a system in which a redundant service processor is installed, a problem was fixed that was preventing the system from booting (with error code B155B06F) when one service processor encountered a problem collecting vital product data (VPD).
• A problem was fixed that caused a system with only a primary service processor installed to report the state of the secondary as "broken" instead of "not installed"; this prevented a firmware installation on the primary service processor.
• A problem was fixed that caused the error logs to be cleared on the secondary service processor when it was rebooted.
• In a system with a redundant service processor, a problem was fixed that prevented a service processor fail-over from completing if a hardware error occurred before the fail-over.
• In a system with a redundant service processor, a problem was fixed that was causing a 11005000 or 11005001 error code to be logged during an administrative failover.
• In a system with a redundant service processor, a problem was fixed that was causing a partition's time-of-day (TOD) clock to jump forward a large amount of time after a failover to the secondary service processor.  If this problem is encountered after this level of firmware is installed, the partition will have to be rebooted to correct the TOD clock.
• In a system with a redundant service processor, a problem was fixed that was causing an invalid error code (B181E436) to be generated during a concurrent firmware update.
• In a system with a redundant service processor, a problem was fixed that was preventing the system from being powered on or powered off after a surveillance failover during a power transition (with error code B181E664).
• A problem was fixed that was preventing a PCI adapter from configuring in a tower after concurrent maintenance on the slot.  If this problem is encountered, the system must be rebooted for the adapter to be correctly configured after the repair.  After this fix is concurrently activated, it will prevent the problem from reoccurring.
• A problem was fixed that caused some error log entries not to be seen on the HMC.
• A problem was fixed that caused multiple B176871C error codes to be generated.
• A problem was fixed that caused an error log entry with error code B1xxE661 to be erroneously generated after an HMC-initiated system firmware installation.
• A problem was fixed that caused some error codes not to be sent to the control (operator) panel when i5/OS failed; instead, D200C2FF is left in the control panel display.  The terminating SRC can be found in the ASMI error logs.  This problem is only seen on i5 systems in default mode without an HMC attached.
• A problem was fixed that may be encountered during a reset/reload of the service processor; the symptom is a system failure with a B7000103 error code.  If this problem is encountered, the system must be rebooted to recover.  When this fix is concurrently activated, it will prevent the problem from reoccurring.
• A problem was fixed that was seen on an HSL Opticonnect cluster when there were more than 10 partitions on either system in the Opticonnect cluster; the failure occurred during a partition boot. 
•  If you are currently affected by this problem, a server IPL must be performed  to   reactivate the low-level HSL Opticonnect connection between the  servers. 
• This problem can be avoided by manually starting the partitions individually instead of using "autostart" to start the partitions. 
• Concurrently activating this fix will prevent the problem from occurring again.
• A problem was fixed that occurred during server boot on a server with a redundant service processor installed; the server hangs at progress code C700406E. 
•  If the server is currently hung at C700406E, this level of firmware can be installed disruptively from the HMC, and the problem will be resolved when the system is automatically rebooted after the installation. 
• If the server is not hung, this level of firmware can be applied concurrently.

• On model 570 systems with more than one processor drawer, a problem was fixed that was preventing enclosure VPD keywords from being changed in the second, third, and fourth processor drawers using the ASMI menus.
• The firmware was enhanced so that the progress codes that indicate discovery of the secondary service processor are displayed on the control (operator) panel.

• On a system that is not managed by an HMC, progress codes were being displayed on the potential firmware consoles; this caused the console selection message to scroll off the screen.
• A problem was fixed that caused error code 11002600 SRC to be generated during the power-down sequence, and a failure of the subsequent power-on with error code B150F22A.

01/13/06 
 

System firmware changes that affect models 590 and 595, other HMC-controlled servers, and clustered systems:

• Fixed a problem that was causing error code B1xx100A to be logged when an HMC was disconnected from a managed system.  This problem is much more likely to occur on managed systems that have two or more HMCs attached, but it can also be seen on systems with only one HMC attached.
• Fixed a problem that caused commands involving LEDs to time out on large, heavily configured systems. 
• A new function was added to system firmware to allow power code downloads to towers to be enabled and disabled.  On eServer systems with a large number of towers, this allows customers to shorten the downtime after a system firmware installation by disabling the power code download to the towers, then enabling it at a convenient time. 

• Supports Double Data Rate (DDR) PCI adapters in DDR PCI slots in the following systems:  9111-520, 9131-52A, 9113-550,  9133-55A, 9111-285, 9405-520, and 9406-520.  Running a DDR PCI adapter in a DDR PCI slot in one of these models with a firmware level prior to this one may result in a potential data error.  IBM recommends that you install this level immediately if using a DDR PCI adapter.

In SF230_156, this fix is CONCURRENT. 

2.  In firmware level SF230_153 (which is also part of ECA 823), there was a deferred fix that affects model 59x systems: 

HIPER:  The hardware initialization settings were changed to fix an incorrect timeout setting in the non-cacheable unit (NCU). The current settings may cause a system checkstop, which could result in a system or partition crash.  This is also known as the  "EMQ hang" problem. 

In SF230_156, this fix is CONCURRENT.  Also, the recovery time for the EMQ hang was improved to benefit HACMP configurations. 
 

System firmware changes that affect all p5 and i5 systems:

• HIPER: An incorrect initialization setting in the shared memory interface  (SMI) may cause a system checkstop, which could result in a system or partition crash. This is also known as the "SMI parity error" issue. 
• HIPER:  Fixed a firmware problem that caused the system to interpret a machine condition as requiring special attention handling, where no special attention existed. This could result in a system checkstop (with error codes B181F647 and B110F139).  This problem is also known as the "master attention alone" issue.

• DEFERRED and HIPER:  A potential server checkstop issue exists in clusters using p5 models p575, p590, and p595, when these models are used to execute compute-intensive applications tuned with the November Power5 Fortran compiler.  Clusters executing applications that are compiled for optimal performance by utilizing the software pre-fetch function are exposed to a server checkstop (B1xxE500). Hardware initialization settings were changed to fix this problem and  the performance tools modified to take these new settings into account.
• HIPER  On systems with a high performance switch (HPS) network adapter installed, fixed a problem that caused a checkstop when memory was moved from a partition that did not own an HPS network adapter. problem was fixed that prevented I/O towers from being concurrently added to i5 systems.
• A problem was fixed that was preventing partitions with large amounts of memory from booting successfully.
• The firmware was changed so that the time it takes to remove a large amount of memory from a partition using a DLPAR (dynamic LPAR) operation is reduced.
• A problem was fixed that was causing enhanced error handling (EEH) error codes to be erroneously generated on 7040-61D I/O drawers when certain adapter card configurations were heavily stressed by the application code.

• On p5 systems that are not managed by an HMC, the timeout for firmware installations performed by the operating system ("in-band" installations) was increased.

Attention: An IPL is required to activate a deferred fix, the system must be powered off via the HMC, (i.e. HMC state=Power OFF) and then powered back on. 

• DEFERRED Changed the initialization settings of the memory buffers to eliminate spurious checkstops that were causing system and partition crashes.
• DEFERRED  On model 590 and 595 systems, fixed a problem that was causing DDR II memory cards in slots C10 and C12 to fail the memory test during a slow-mode boot.
