System firmware changes that affect all systems

• A problem was fixed that caused a card (and its children) that was removed after the system was booted to continue to be listed in the guard menus in the Advanced System Management Interface (ASMI).
• A problem was fixed that prevented predictive guard errors from being deleted on the secondary service processor.  This caused hardware to be erroneously guarded out if a service processor failover occurred, then the system was rebooted.
• A problem was fixed that caused SRC B1813221, which indicates a failure of the battery on the service processor, to be erroneously logged after a service processor reset or power cycle.
• A problem was fixed that caused various SRCs to be erroneously logged at boot time including B181E6C7 and B1818A14.
• A problem was fixed that caused a code update operation to fail with a time-out error, creating a call-home with SRC B1818A0F .  This problem is more likely to occur on HMC-managed systems experiencing a high level of management activity during a code update.
• A problem was fixed that caused system fans to be erroneously called out as failing with one or more of the following SRC's: 11007610,11007620,11007630,11007640, or 11007650.
• A problem was fixed that caused the service processor (or system controller) to crash when it boots from the new level during a concurrent firmware installation.
• A problem was fixed that caused SRC B7006A72 to be erroneously logged.
• A problem was fixed that caused the system power to be throttled, resulting in decreased performance.  This problem typically occurs after a PCI adapter is plugged into a node (CEC drawer), and can also happen when a dedicated I/O partition is powered on or off.
• The Power Hypervisor was enhanced to insure better synchronization of vSCSI and NPIV I/O interrupts to partitions.
• A problem was fixed that caused SRC B15A3303 ("CEC Hardware: Time-Of-Day Hardware Predictive Error") to be erroneously logged, and the time-of-day to be set to Jan 1, 1970.
• A problem was fixed that was caused by an attempt to modify a virtual adapter from the management console command line when the command specifies it is an Ethernet adapter, but the virtual ID specified is for an adapter type other than Ethernet.  The managed system has to be rebooted to restore communications with the management console when this problem occurs; SRC B7000602 is also logged.

• On systems with an I/O tower attached, a problem was fixed that caused SRCs 10009135 and 10009139 to be erroneously logged.
• A problem was fixed that caused various parts to be erroneously guarded out in some cases, and the clock card being called out as defective in other cases, when both ac cords providing power to a drawer were unplugged when the system was powered on.
• On systems running Selective Memory Mirroring (SMM), a problem was fixed that caused the hypervisor to hang or crash when an uncorrectable hardware error occurred in a memory DIMM.
• On systems with redundant service processors, a problem was fixed that caused the sibling service processor state to show up as "unknown" in the service processor error log if a code synchronization problem was detected after a service processor was replaced.
• On systems with an I/O tower attached, a problem was fixed that caused multiple service processor reset/reloads if the tower was continuously sending invalid System Power Control Network (SPCN) status data.
• A problem was fixed that caused the HMC to display incorrect data for a virtual Ethernet adapter's transactions statistics.
• A problem was fixed that caused a hibernation resume operation to hang if the connection to the paging space is lost near the end of the resume processing.  This is more likely on a partition that supports remote restart.
• A problem was fixed that caused the system to terminate with a bad address checkstop during mirroring defragmentation.
• A problem was fixed that prevented the HMC command "lshwres" from showing any I/O adapters if any adapter name contained the ampersand character in the VPD.
• On a system running a Live Partition Mobility (LPM) operation, a problem was fixed that caused the partition to successfully appear on the target system, but hang with a 2005 SRC.
• On a partition with a large number of potentially bootable devices, a problem was fixed that caused the partition to fail to boot with a default catch, and SRC BA210000 may also be logged.
• On systems running Active Memory Sharing (AMS) partitions, a problem was fixed that may arise due to the incorrect handling of a return code in an error path during the logical partition migration (LPM) of an AMS partition.
• On systems running Active Memory Sharing (AMS) partitions, a timing problem was fixed that may occur if the system is undergoing AMS pool size changes.
  

• A problem was fixed that caused SRC B15738B0 to be erroneously logged after a successful concurrent hot add/repair maintenance operation.
• A problem was fixed that caused a concurrent hot add/repair maintenance (CHARM) operation to fail after this sequence of events occurred:
  
                      1.  A user-initiated platform system dump is requested (from the ASMI or management console).
                      2.  A service processor reset/reload takes place while dump collection is in progress.
                      3.  A concurrent hot add/repair maintenance operation is attempted.

• On systems in which there are no processors in the shared processor pool, a problem was fixed that caused the Hypervisor to become unresponsive (the service processor starts logging time-out errors against the Hypervisor, and the HMC can no longer talk to the Hypervisor) during a concurrent hot add/repair maintenance operation.
  
• A problem was fixed that caused a hypervisor memory leak during a concurrent hot add/repair maintenance operation.
• A problem was fixed that caused a concurrent node repair or upgrade to fail during the system deactivation step with a hypervisor error code of 0x300.
  
• A problem was fixed that caused a the system to terminate with a bad address checkstop during a concurrent hot add/repair maintenance operation.
• A problem was fixed that caused the system to hang if memory relocation is performed during a concurrent hot add/repair maintenance operation.
• A problem was fixed that caused partition activations to fail during or after a node repair operation.
• A problem was fixed that caused synchronization problems in an application using the Barrier Synchronization Register (BSR) facility during the memory relocation that occurs in a concurrent hot add/repair maintenance operation.
• A problem was fixed that prevented the I/O slot information from being presented on the management console after a concurrent node repair.
• On systems running multiple IBM i partitions that are configured to communicate with each other via virtual Opticonnect, concurrent hot add/repair maintenance operations may time-out.  When this problem occurs, a platform reboot may be required to recover.
  

System firmware changes that affect all systems

• HIPER/Non-Pervasive: DEFERRED:  A problem was fixed that caused a system crash with SRC B170E540.
• HIPER/Non-Pervasive:  A related problem was also fixed that could cause a live lock on the power bus resulting in a system crash.
• To address poor placement of partitions following a reboot of a server with unlicensed cores, the firmware was enhanced to run the affinity manager when the initialize configuration operation is done from the HMC.  A problem was also fixed that caused the hypervisor to be left in an inconsistent state after a partition create operation failed.

New Features and Functions

• The firmware was enhanced to fix a potential performance degradation on systems utilizing the stride-N stream prefetch instructions dcbt (with TH=1011) or dcbtst (with TH=1011).  Typical applications executing these algorithms include High Performance Computing, data intensive applications exploiting streaming instruction prefetchs, and applications utilizing the Engineering and Scientific Subroutine Library (ESSL) 5.1.
• On systems on which Internet Explorer (IE) is used to access the Advanced System Management Interface (ASMI) on the Hardware Management Console (HMC), a problem was fixed that caused IE to hang for about 10 minutes after saving changes to network parameters on the ASMI.
• A problem was fixed that caused informational SRC A70047FF, which may indicate that the Anchor (VPD) card should be replaced, to be erroneously logged again after the Anchor card was replaced.

• A problem was fixed that prevented the user from changing the boot mode or keylock setting after a remote restart-capable partition is created, even after the partition's paging device is on-line.

• The firmware resolves undetected N-mode stability problems and improves error reporting on the feature code (F/C) 5802 and 5877 I/O drawer power subsystem.
  

System firmware changes that affect all systems

• The firmware was enhanced to properly display a memory controller that has been guarded out manually on the "Deconfiguration Records" menu option (under "System Service Aids") on the Advanced System Management Interface (ASMI).
  
• A problem was fixed that caused multiple service processor dumps to be unnecessarily taken during a concurrent firmware update.  SRC B181EF9A, which indicates that the dump space on the service processor is full, was logged as a result.
• The firmware was enhanced to increase the threshold for recoverable SRC B113E504 so that the processor core reporting the SRC is not guarded out.  This prevents unnecessary performance loss and the unnecessary replacement of processor modules.
• A problem was fixed that caused SRC B7000602 to be erroneously logged at power on.
• The firmware was enhanced to recognize new USB-attached devices so that they will be listed as boot devices in the System Management Services (SMS) menus.
• A problem was fixed that caused booting or installing a partition or system from a USB device to fail with error code BA210012.  This usually occurs when an operating system (OS) other than the OS that is already on the partition or system is booted or installed.
• On the System Management Services (SMS) remote IPL (RIPL) menus, a problem was fixed that caused the SMS menu to continue to show that an Ethernet device is configured for iSCSI, even though the user has changed it to BOOTP.
  
• The firmware was enhanced to log SRCs BA180030 and BA180031 as informational instead of predictive.
• The firmware was enhanced to increase the threshold of soft NVRAM errors on the service processor to 32 before SRC B15xF109 is logged.  (Replacement of the service processor is recommended if more than one B15xF109 is logged per week.)
  
• A problem was fixed that caused a system to crash when the system was in low power (or safe) mode, and the system attempted to switch over to nominal mode.
  
• On a multi-drawer system, a problem was fixed that prevented the system attention LED from correctly reflecting the status of the DASD fault LEDs in drawers 2, 3, and 4.
• A problem was fixed that caused the system to fail to boot with SRC B1xxB507.
• A problem was fixed that prevented a node from being deconfigured manually using the  Advanced System Management Interface (ASMI).
• A problem was fixed the caused system fans to be erroneously called out as failing.
  

• A problem was fixed that caused the hypervisor to hang during a concurrent operation on a F/C 5802, 5803, 5873 or 5877 I/O drawer.  Recovering from the hypervisor hang required a platform reboot.
  
• A problem was fixed that impacted performance if profiling was enabled in one or more partitions.  Performance profiling is enabled:
  - In an AIX or VIOS partition using the tprof (-a, -b, -B, -E option) command or pmctl (-a, -E option) command.
  - In an IBM i partition when the PEX *TRACE profile (TPROF) collections or PEX *PROFILE collections are active.
  - In a Linux partition using the perf command, which is available in RHEL6 and SLES11; profiling with oprofile does not cause the problem.
• A problem was fixed that prevented the operating system from being notified that a F/C 5802 or 5877 I/O drawer had recovered from an input power fault (SRC 10001512 or 10001522).
  
• On a system that is being upgraded from Ax720 system firmware to Ax730 system firmware, the firmware was enhanced to log B1818A0F as informational instead of predictive if it occurs during the firmware upgrade.
• On systems running Active Memory Sharing (AMS), the allocation of the memory was enhanced to improve performance.
• A problem was fixed that caused the suspension of a logical partition running Active Memory Sharing (AMS) to fail because the disk headers had not been erased.
• On systems with an iSCSI network, when booting a logical partition using that iSCSI network, a problem was fixed that caused the iSCSI gateway parameter displayed on the screen to be incorrect.  It did not impact iSCSI boot functionality.
• On systems running Active Memory Sharing (AMS) and Active Memory Mirrorring (AMM), a problem was fixed that caused memory allocation to fail.  This in turn caused a partition to fail to boot with SRC A2009030.
• On systems using affinity groups, a problem was fixed that prevented one of the partitions from being placed correctly.
• On 9117-MMB and 9179-MHB systems without an optional GX adapter, a problem was fixed that caused the system fans to ramp up to their maximum speed.
  

• A problem was fixed that caused a checkstop to occur during a node repair operation.
• A problem was  fixed that caused the system to hang during a CHARM operation.
• A problem was fixed that caused multiple types of failures (CHARM node  operations and Advanced Energy Manager (AEM) state changes, among others), after a CHARM hot node operation on the first (top) drawer was followed by a concurrent firmware installation.
• On systems with more than one node, a problem was fixed that caused a CHARM operation on node B to fail with a Repair and Verify (R&V) panel that indicated a "Deactivate power domain for the FruType.CEC_ENCLOSURE at U78C0.001.xxxxxx" failure due to a "0x0007 COMMAND_TIMEOUT".
  

System firmware changes that affect certain systems

• HIPER/Pervasive on systems with a Virtual Input/Output (VIO) client running AIX, and with a F/C 5802 or 5877 I/O drawer attached:  A problem was fixed that caused the system to crash with SRC B700F103.

System firmware changes that affect all systems 

• HIPER/Pervasive:  On systems running firmware level AM730_049 or AM730_058, a problem was fixed that caused the target server to hang, or go to the incomplete state on the management console, after a Live Partition Mobility (LPM) operation.  This problem can also occur when a partition hibernation operation is done.
