 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:  On systems with a redundant service processor, a problem was fixed that caused the system to terminate with SRC B1xx951C after a failover to the secondary service processor.  This problem can also cause the system to terminate with SRC B1xx9523 after a reset/reload of the primary service processor.
•  A problem was fixed that was causing multiple service processor reset/reload operations with SRC B1817201. 
• On a partitioned system running i5/OS, a problem was fixed that caused error CPF9E75 ("i5/OS usage limit exceeded - operator action required") to be posted about once an hour, even though the system had a valid number of processor licenses. 
• The firmware was changed so that HMC surveillance errors with SRC B1xxE433 are logged as informational (without hardware callouts) instead of predictive. 
• On systems with a redundant service processor, a problem was fixed that caused a service processor failover to fail with SRC B181E911.
• On systems with a redundant service processor, a problem was fixed that caused platform dump data files to be unavailable from the new primary service processor after a service processor failover.
• On systems with a redundant service processor, a problem was fixed that caused SRC B1818A0E to be logged when the system was rebooted after a dump was captured.
• A problem was fixed that caused the managed system to appear to be hung when viewed from the HMC. 
• On model 590 and 595 systems,SF240_298 is the minimum firmware level required for FC 4503 CUoD DDR2 memory cards.

• 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.
• On model 561 systems, a problem was fixed that caused B181B08E to be erroneously posted during the cold repair of a service processor.  This problem may occur in systems with processor feature code 7295 or 7781 installed.
• A problem was fixed that might prevent the system from booting to runtime with power SRCs 11008456 and 110015x4, even though the power subsystem was functioning within specifications. 

• HIPER:  A problem was fixed that caused the system to crash with SRC B150D133. A system dump is generated as a result of the problem (SRC B181F03B).
• HIPER:  A problem was fixed that caused the system or partition to crash when corruption was detected in low memory.
• HIPER: A problem was fixed that caused I/O paths to be deconfigured after certain types of failures, indicated by SRC B170100A, until no I/O paths were left.  The firmware has been changed so that the I/O paths are no longer deconfigured under these circumstances.
• DEFERRED:  A change was made to improve the reliability of system memory.  This change reduces the likelihood of SRC B123E500 occurring, and also reduces the likelihood of a system crash with SRC B1xxF667.
• A problem was fixed that caused the "ping" command in the system management services (SMS) to fail during a NIM installation.
• A problem was fixed that caused a large number of B181C00A SRCs to be erroneously posted in the service processor's error log.
• A problem was fixed that caused the service processor to run out of memory with SRC B1817201 and generate a service processor dump. 
• A problem was fixed that prevented the service processor's serial ports from being configured to run at 50 baud and 2400 baud.
• A problem was fixed that prevented the protocol menu in the system management services (SMS) menu for virtual LAN adapters from being displayed. 
• A problem was fixed that caused AIX to incorrectly report errors that occurred during booting and were then passed to the AIX error log.
• A problem was fixed that prevented a beep or bell sound from being heard when an error occurred in an X window.
• A problem was fixed that erroneously caused a service processor dump when a power-off request was issued before a reboot that was in progress was complete.
• The firmware was changed so that SRC B1xx3008 will not be reported to the error logs during and after a concurrent firmware update.
• The firmware was changed so that SRCs B1xxE676, B1xxE678, and B1xxE67A will not be reported during and after a concurrent firmware update unless a threshold is reached.

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 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.

• 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.

• 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.

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.

04/03/06

Two fixes that were deferred in earlier levels are concurrent in this level:

1.  In firmware level SF230_150, there was a deferred fix that affects all p5 and i5 systems: 

HIPER:  The initialization settings of the memory buffers were changed to eliminate spurious checkstops that were causing system and partition crashes. 

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.
