System firmware changes that affect all systems

• HIPER: A problem was fixed that caused the system to crash with SRCs B700F103 and B181F0E7, if the server was running AIX and had a  F/C 5802 or 5877 drawer (in a 19" rack), or F/C 5803 or 5873 drawer (in a 24" rack), attached.
• DEFERRED:   This fix corrects the handling of a specific processor instruction sequence that has the potential to result in undetected data errors.  This specific instruction sequence has only been observed in a small number of highly tuned Floating Point intensive applications.  However, it is strongly recommended that this fix be applied to all POWER6 systems.  This fix has the potential to decrease system performance on applications that make extensive use of floating point divide, square root, or estimate instructions.
  
• A problem was fixed that prevented an SRC from being recorded in the service processor dump produced by a host-initiated reset.
• A problem was fixed that caused SRC 10009135, followed by 10009139, to be erroneously logged.  These SRCs indicate a system power control network (SPCN) loop is being broken, then re-established.
• A problem was fixed that, under certain rare circumstances, caused a partition to hang when being shut down.
• A problem was fixed that caused the system to hang with SRCs B182953C, B182954C and B17BE434 being logged.
• The firmware was enhanced to detect and handle 12X InfiniBand I/O drawer cabling errors better.
• A problem was fixed that, under certain rare circumstances, caused the system to become unresponsive and appear to hang  when page migration occurred on a PCIe slot.

• A problem was fixed that caused a virtual SCSI or virtual fibre channel adapter to be seen by the operating system as not bootable when it was added to a partition using a dynamic LPAR (DLPAR) operation.
• On systems running IBM i, a problem was fixed that caused booting the operating system from a fibre channel device to fail with SRC 576B8301.
• On systems with a F/C 5802 or 5877 drawer attached, a problem was fixed that could impact the performance of a 4-port Ethernet adapter F/C 5272, 5275, 5279, 5280, 5525, 5526, or 5527 installed in that drawer.
• In partitions running AIX or Linux, a problem was fixed that caused the addition of an I/O slot to a partition using a dynamic LPAR (DLPAR) add operation to fail.
• On systems with shared processors, a problem was fixed that caused the partitions to hang and become unresponsive for very short periods of time.
• A problem was fixed that prevented the IPv6 DHCP address from being displayed on the advanced system management interface (ASMI) network configuration screens when IPv6 and DHCP were enabled.  This only occurred on systems with virtual LAN (VLAN) addresses (such as eth0.30, eth0.31), and when IPv6 addresses were assigned to the eth0.xx interface.
• On systems running redundant VIOS partitions, a problem was fixed that prevented Ethernet traffic from being properly bridged between the two partitions.  This problem also prevented shared Ethernet adapter failover from working correctly.

Concurrent maintenance (CM) firmware fixes 
• A problem was fixed that prevented the concurrent repair of a redundant service processor.
• A problem was fixed that caused unpredictable system behavior if a capacity on demand (CoD) or a virtualization engine technology (VET) activation code was entered and accepted after a node 0 evacuation was done.  The unpredictable machine behavior might also have occurred, if a node 0 evacuation failed, a system dump was taken, and a memory-preserving IPL was then initiated.
• A problem was fixed that caused a concurrent maintenance operation after a node evacuation to fail.  When this problem occurred, the system erroneously states that a platform memory dump is pending.
• A problem was fixed that prevented a concurrent maintenance operation from completing successfully.

• The firmware was enhanced to handle system dumps (SYSDUMPs) larger than 4GB in size.
• On systems running system firmware release EM340, a problem was fixed that caused a dynamic LPAR (DLPAR) operation on memory to fail until the platform was rebooted.
• The firmware was enhanced to improve the performance of the F/C 5732, 5735 and 5769 PCI-E adapters.
• A problem was fixed that caused a repair and verify (R&V) operation on the HMC to fail with the message "Exception encountered while rendering panel as HTML".
• The firmware was enhanced such that SRCs B181F126, B181F127, and B181F129 are correctly logged, and no longer calls home unnecessarily for these SRCs.

• A problem was fixed that caused a system or partition running Linux to crash when the "serv_config -l" command was run.
• On systems running active memory sharing (AMS), the firmware was enhanced so that error messages indicating "out of compliance" issues with the memory (HMC SRC HSCL031F) will not be generated if the user allocates more memory than is installed in the system.  (Allocating more memory than is installed in the system is supported in active memory sharing.)
• A problem was fixed that caused the hypervisor to loop unnecessarily and consume too many processor cycles.  This impacted the performance of the system.

• The firmware was enhanced such that SRC B181F126 is correctly managed, and no longer calls home  unnecessarily for this problem.

08/20/09

System firmware changes that affect all systems

• DEFERRED:  This fix corrects the handling of a specific processor instruction sequence that was generated on a particular heavily-tuned High Performance Computing (HPC) application. This specific instruction sequence has the potential to produce an incorrect result. This instruction sequence has only been observed in a single HPC application.  However, it is strongly recommended that you apply this fix. 

• HIPER:  for systems with F/C 5802 or 5877 drawers attached:  A problem was fixed that prevented node concurrent maintenance operations on systems with F/C 5802 or 5877 drawers attached to them.
• On systems with F/C 5802 or 5877 drawers attached, a problem was fixed that prevented an I/O slot's power LED from accurately reflecting the state of the I/O slot in a 5802 or 5877 drawer, under certain circumstances.
• On systems running system firmware EM340_075 and Active Memory Sharing, a problem was fixed that might have caused a partition to fail to boot with SRC B700F103 if the partition had more than 24 virtual processors assigned to it.
• On systems running system firmware EM340_075 and Active Memory Sharing, a problem was fixed that might have caused a partition to lose I/O entitlement after the partition was moved from one system to another using PowerVM Mobility.

• On systems with external I/O towers attached, the firmware was enhanced so that the system will not crash when SRC B7006981 is logged for certain types of I/O hardware failures. 

• On model MMA systems, the firmware was enhanced such that an invalid enclosure serial number will not cause the node evacuation phase of a concurrent maintenance operation to fail.  A small number of model MMA enclosures may have an invalid serial number (such as "DQ1234 " or "DQ1234#) due to the I/O backplane having been replaced in a previous maintenance operation.
• A problem was fixed that might have caused the performance of an I/O loop (attached to a 12X I/O adapter) to be degraded if a B7006982, B7006984, B7006985, B70069F2, B70069F3, or B70069F4 SRC is logged after a concurrent maintenance operation on that loop.
• A problem was fixed that caused concurrent maintenance operations on memory DIMMs to fail if the replacement DIMMs were functionally equivalent to the original DIMMs, but did not have the same CCIN (customer card identification number).

• A problem was fixed that caused the system to crash during a hot node or GX adapter repair with certain hardware configurations.
• A problem was fixed that caused the system to crash during a hot node repair or upgrade.

05/26/09

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.

• The firmware was enhanced such that if an attempt is made to enable redundancy when the system is booting, the error log entry that is made will be informational instead of predictive.
• The firmware was enhanced so that a call home will be made if the hypervisor issues a "terminate immediate" interrupt.
• The firmware was enhanced so that the service processor only logs SRC B1A38B24 when a valid network setup error is found. The callouts for this SRC were also improved.
• The firmware was enhanced so that SRCs B181720D, B1818A13, and B1818A0F, and occasionally a service processor dump, will not be generated when the service processor's two Ethernet interfaces are on the same subnet. (This is an invalid configuration.)

• In systems using InfiniBand switches for processor clustering, a problem was fixed that caused packets to be dropped under certain circumstances.
• A problem was fixed that caused the migration of a partition with more than 900 virtual slots defined, from a system running firmware EM320 to a system running firmware EM340, to fail.
• On systems running firmware release EM340, a problem was fixed that caused data in the platform dump to be invalid.

• 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: A problem was fixed that caused SRC B150A422 to be erroneously logged, and the advanced system management interface (ASMI) to erroneously show deconfigured processor cores, if system firmware was installed while a node was deactivated due a concurrent maintenance operation.
• DEFERRED: A problem was fixed that caused SRC B181B171 to be logged, and the system to crash, during a concurrent node repair or concurrent GX adapter repair.
• A problem was fixed that might cause a concurrent node repair, a concurrent I/O expansion unit repair, a concurrent PCI slot repair, or a DLPAR removal or moving of I/O slots to fail if the I/O hardware involved is in a failed state. 
• 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 EM340_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.

04/20/09

• 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.
• The firmware was enhanced to improve the service processor's capability to recover from bad bits in the flash memory.

• A problem was fixed that caused a partition being migrated to become unresponsive on the target system when firmware-assisted dump was enabled.
• The firmware was enhanced so that SRC BA210012 will not generate a call home when logged.
• 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.
• A problem was fixed that prevented all of the necessary files from being synchronized between the primary and secondary service processors. One possible symptom of this problem was the time-of-day clocks being out of synch after a service processor failover.

• On systems with external I/O drawers, a problem was fixed that could cause the system to hang on checkpoint C700406E during a "warm" reboot (a reboot in which the processor drawer is power-cycled but the I/O drawers are not).
• On systems running system firmware release EM340 and IBM i partitions, a problem was fixed that caused message CPF9E7F, CPF9E2D or CPF9E5E (which indicates a licensing key problem) to be received by the IBM i partitions when the number of physical processors was greater than the number of IBM i licenses.
• On systems with virtual fiber channel disks, a problem was fixed that prevented the system management services (SMS) from displaying the virtual fiber channel disks if the virtual fiber channel server reported that any of them were reserved. 

• 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.

• DEFERRED:  This fix corrects the handling of a specific processor instruction sequence that was generated on a particular heavily-tuned High Performance Computing (HPC) application. This specific instruction sequence has the potential to produce an incorrect result. This instruction sequence has only been observed in a single HPC application.  However, it is strongly recommended that you apply this fix.

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.
• 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 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 prevented all of the necessary files from being synchronized between the primary and the secondary service processors. One possible symptom of this problem was the time-of-day clocks being out of synch after a service processor failover.

• 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.
• On systems with multiple host channel adapter (HCA) cards, a problem was fixed that logical ports on the HCA cards to be intermittently inactive.

• 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.

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.

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.

• 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.

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 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.

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

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.

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.
