Power8 System Firmware

Applies to:   9119-MHE and 9119-MME.

This document provides information about the installation of Licensed Machine or Licensed Internal Code, which is sometimes referred to generically as microcode or firmware.


Contents


1.0 Systems Affected

This package provides firmware for Power System E880 (9119-MHE ) and Power System E870 (9119-MME) servers only.

The firmware level in this package is:

1.1 Minimum HMC Code Level

This section is intended to describe the "Minimum HMC Code Level" required by the System Firmware to complete the firmware installation process. When installing the System Firmware, the HMC level must be equal to or higher than the "Minimum HMC Code Level" before starting the system firmware update.  If the HMC managing the server targeted for the System Firmware update is running a code level lower than the "Minimum HMC Code Level" the firmware update will not proceed.

The Minimum HMC Code level for this firmware is:  HMC V8 R8.4.0 (PTF MH01559) with Mandatory ifix (PTF MH01560).

Although the Minimum HMC Code level for this firmware is listed above,  HMC V8 R8.4.0 Service Pack 1 (PTF MH01576) with iFix (PTF MH01639) or higher is recommended.

For information concerning HMC releases and the latest PTFs,  go to the following URL to access Fix Central:
http://www-933.ibm.com/support/fixcentral/

For specific fix level information on key components of IBM Power Systems running the AIX, IBM i and Linux operating systems, we suggest using the Fix Level Recommendation Tool (FLRT):
http://www14.software.ibm.com/webapp/set2/flrt/home

NOTES:
                -You must be logged in as hscroot in order for the firmware installation to complete correctly.
                - Systems Director Management Console (SDMC) does not support this System Firmware level.

1.2 AIX iFix Required

For IBM Power System servers with the PCIe 2-port Async EIA-232 Adapter installed on AIX partitions, an AIX fix resolving the async port interrupt handling (APAR IV77596) must be installed before updating to the SC840_056 (FW840.00) or later level of firmware.  The ports on the adapter (feature code EN27/EN28, CCIN 57D4) may become un-usable with the installation of that firmware level due to an issue with how interrupts are handled.  Many JAS_RTS error log entries are written to the error log due to this issue.

Prior to this APAR shipping in a future Service Pack, AIX intends to publish ifixes for the latest Service Packs on all active Technology Levels on our ftp server, in ftp://aix.software.ibm.com/aix/ifixes/iv77596/ on or before Oct 13, 2015.  If you need an ifix other than the ones on this server, contact IBM support to request one for your specific situation.

The procedure is intended to be performed by the customer.  In the event that the customer has questions or concerns with the procedure, you should contact IBM Support.  Please contact IBM Support:

2.0 Important Information

Downgrading firmware from any given release level to an earlier release level is not recommended.

If you feel that it is necessary to downgrade the firmware on your system to an earlier release level, please contact your next level of support.

2.1 IPv6 Support and Limitations

IPv6 (Internet Protocol version 6) is supported in the System Management Services (SMS) in this level of system firmware. There are several limitations that should be considered.

When configuring a network interface card (NIC) for remote IPL, only the most recently configured protocol (IPv4 or IPv6) is retained. For example, if the network interface card was previously configured with IPv4 information and is now being configured with IPv6 information, the IPv4 configuration information is discarded.

A single network interface card may only be chosen once for the boot device list. In other words, the interface cannot be configured for the IPv6 protocol and for the IPv4 protocol at the same time.

2.2 Concurrent Firmware Updates

Concurrent system firmware update is only supported on HMC Managed Systems only.

2.3 DPSS Updates

The DPSS updates occur if there is a DPSS image change  between the current firmware level and the new firmware level. 
If there is a change and the code update is concurrent, the DPSS update is delayed to the next IPL of the CEC and it will cause an additional 18 to 20 minutes to be added on to the IPL for the power on step.  On the HMC, DPSS code update progress codes will be displayed but they are often overwritten by the HMC connecting state with  "No Connection" status message.
If there is a change and the code update is disruptive, the DPSS update occurs during the code update when it does a reset/reload of the service processor to activate the new code level.  When the service processor is resetting to service processor stand-by state, it will code update the DPSS and add 18 to 20 minutes to this transition.  On the HMC, DPSS code update progress codes will be displayed but tehy are often overwritten by the HMC  connecting state with "No Connection" status message.

New DPSS code update progress codes:

C100C300 = The FSP firmware has started the DPSS download application.
C100C301 = The DPSS download application is waiting for appropriate interface devices to be configured and ready.
C100C302 = The DPSS download application is reading the DPSS image information for system type and revision checks.
C100C303 = The DPSS download application has determined that this system type has a single DPSS.
C100C304 = The DPSS download application has determined that this system type has multiple DPSS devices.
C100C310 = The DPSS download application has started checking if a DPSS device will require an image download.
C100C311 = The DPSS download application is reading the revision information from a DPSS device.
C100C312 = The DPSS download application is checking the system power state (on or off).
C100C313 =  The DPSS download application is resetting the DPSS download lockout line to allow an image to be written.
C100C314 =  The DPSS download application is configuring the interfaces used to write the DPSS image.
C100C315 =  The DPSS download application is locking out other FSP applications from DPSS IIC communications.
C100C320 =  The DPSS download application is writing the DPSS image on a single DPSS system type.
C100C321 =  The DPSS download application has successfully written the DPSS image on a single DPSS system type.
C100C330 =  The DPSS download application is writing the DPSS image via SPI interface (one of multiple DPSS devices).
C100C331 =  The DPSS download application has successfully written a DPSS image via the SPI interface.
C100C340 =  The DPSS download application is unlocking the DPSS IIC interface to allow other FSP applications to communicate with the DPSS.
C100C350 =  The DPSS download application is verifying that the new DPSS image is written correctly and functioning.
C100C360 =  The DPSS download application is updating the FSP registry information to indicate current DPSS revision(s) and type(s).
C100C3FA = The DPSS download application has encountered a failure in communicating with a DPSS or updating a DPSS image.
C100C3FF = The DPSS download application has finished and is exiting normally.

2.4 Memory Considerations for Firmware Upgrades

Firmware Release Level upgrades and Service Pack updates may consume additional system memory.
Server firmware requires memory to support the logical partitions on the server. The amount of memory required by the server firmware varies according to several factors.
Factors influencing server firmware memory requirements include the following:
Generally, you can estimate the amount of memory required by server firmware to be approximately 8% of the system installed memory. The actual amount required will generally be less than 8%. However, there are some server models that require an absolute minimum amount of memory for server firmware, regardless of the previously mentioned considerations.

3.0 Firmware Information

Use the following examples as a reference to determine whether your installation will be concurrent or disruptive.

For systems that are not managed by an HMC, the installation of system firmware is always disruptive.

Note: The concurrent levels of system firmware may, on occasion, contain fixes that are known as Deferred and/or Partition-Deferred. Deferred fixes can be installed concurrently, but will not be activated until the next IPL. Partition-Deferred fixes can be installed concurrently, but will not be activated until a partition reactivate is performed. Deferred and/or Partition-Deferred fixes, if any, will be identified in the "Firmware Update Descriptions" table of this document. For these types of fixes (Deferred and/or Partition-Deferred) within a service pack, only the fixes in the service pack which cannot be concurrently activated are deferred.

Note: The file names and service pack levels used in the following examples are for clarification only, and are not necessarily levels that have been, or will be released.

System firmware file naming convention:

01SCxxx_yyy_zzz

NOTE: Values of service pack and last disruptive service pack level (yyy and zzz) are only unique within a release level (xxx). For example, 01SC830_040_040 and 01SC840_040_045 are different service packs.

An installation is disruptive if:

            Example: Currently installed release is 01SC840_040_040, new release is 01SC850_050_050.

            Example: SC830_040_040 is disruptive, no matter what level of SC830 is currently installed on the system.

            Example: Currently installed service pack is SC830_040_040 and new service pack is SC830_050_045.

An installation is concurrent if:

The release level (xxx) is the same, and
The service pack level (yyy) currently installed on the system is the same or higher than the last disruptive service pack level (zzz) of the service pack to be installed.

Example: Currently installed service pack is SC830_040_040, new service pack is SC830_071_040.

SC840_113_056 / FW840.22

07/06/16
Impact:  Availability      Severity:  ATT

New features and functions

  • Support was added to Live Partition Mobility to allow migrations between partitions at firmware level FW760 and FW840.22 or later.  Previously, migration operations were not allowed between FW760 and FW840 partitions.

System firmware changes that affect all systems

  • Support was added for additional First Failure Data Capture (FFDC) data for processor clock failover errors provided by creating daily clock status reports with SRC B150CCDA informational error logs.  This clock status SRC log is written into the Hardware Management Console (HMC) iqyylog.log as a platform error log (PEL) event.  The PEL event contains a dump of the clock registers.  If a processor clock fails over with SRC B158CC62 posted to the serviceable events log, the iqyylog.log file on the HMC should be collected to help debug the clock problem using the B150CCDA data.  This support had been dropped in FW840.21 because of a IPL initialization conflict that has been resolved and the support is now re-instated.

System firmware changes that affect certain systems

  • On systems using PowerVM firmware, a problem was fixed for a sequence of two or more Live Partition Mobility migrations that caused a partition to crash with a SRC BA330000 logged (Memory allocation error in partition firmware).  The sequence of LPM migrations that can trigger the partition crash are as follows:
    The original source partition level can be any FW760.xx, FW763.xx, FW770.xx, FW773.xx, FW780.xx, or FW783.xx P7 level or any FW810.xx, FW820.xx, FW830.xx, or FW840.xx P8 level.  It is migrated first to a system running one of the following levels:
    1) FW730.70 or later 730 firmware or
    2) FW740.60 or later 740 firmware
    And then a second migration is needed to a system running one of the following levels:
    1) FW760.00 - FW760.20 or
    2) FW770.00 - FW770.10
    The twice-migrated system partition is now susceptible to the BA330000 partition crash during normal operations until the partition is rebooted.  If an additional LPM migration is done to any firmware level, the thrice-migrated partition is also susceptible to the partition crash until it is rebooted.
    With the fix applied, the susceptible partitions may still log multiple BA330000 errors but there will be no partition crash.  A reboot of the partition will stop the logging of the BA330000 SRC.
SC840_111_056 / FW840.21

06/24/16
Impact:  Availability      Severity:  SPE

NOTE:

Critical firmware update for FW840.20 (SC840_104) level systems

System IPLed with FW840.20:  A critical firmware update is required for all 9119-MME and 9119-MHE that have been IPLed with FW840.20 (SC840_104). The FW840.20 level can cause a failed IPL or a potential unplanned outage. If the server is already in production, then customer should plan an outage at a convenient time to apply FW 840.21 (SC840_111) or higher and IPL.

System had FW840.20 concurrently applied:  If firmware level FW840.20 was concurrently installed (i.e. system was NOT IPL'ed after installing the level) customers are not impacted by this issue provided they apply FW840.21 (SC840_111) or higher prior to next planned system reboot. NOTE: FW 840.21 can be applied concurrently.

System IPLed with any other version of Firmware:  If the current firmware level of the system is not FW840.20, the system is not exposed to this issue. Customers can install this level or later at the next scheduled update window.

To verify the firmware level installed on the server, select “Updates” from the left side of the HMC and place a check mark on the server of interest. Then select “View system information” from the bottom view, select “None - Display current values”. The Platform IPL Level will indicate the last level the system was booted on.

System firmware changes that affect all systems

  • A problem was fixed for an intermittent failure in Hostboot during the system IPL resulting in SRCs BC70090F and BC8A1701 logged with a hardware procedure return code of "RC_PROC_BUILD_SMP_ADU_STATUS_MISMATCH".  The system terminates with a Terminate Immediate (TI) condition.  The system must be re-IPLed to recover.  The failure is very infrequent and was caused by a race condition introduced as part of clock card failure data collection procedure which has now been removed (see below).
  • Support was removed for additional First Failure Data Capture (FFDC) data for processor clock failover errors added in FW840.20.   The FFDC was provided by creating daily clock status reports with SRC B150CCDA informational error logs.  This change was removed because it could trigger intermittent IPL & initialization failures.
SC840_104_056 / FW840.20

05/31/16
Impact:  Availability      Severity:  SPE

New features and functions

  • Support for a system control unit (SCU) with three fans instead of four on the E870 (9119-MME) and E880 (9119-MHE) system models.  The SCU fan has CCIN 6B44 with part number 00FV798.
  • Support was added for the Stevens6+ option of the internal tray loading DVD-ROM drive with F/C #EU13.  This is an 8X/24X(max) Slimline SATA DVD-ROM Drive.  The Stevens6+ option is a FRU hardware replacement for the Stevens3+.  MTM 7226-1U3 (Oliver)  FC 5757/5762/5763 attaches to IBM Power Systems and lists Stevens6+ as optional for Stevens3+.  If the Stevens6+  DVD drive is installed on the system without the required firmware support, the boot of an AIX partition will fail when the DVD is used as the load source.  Also, an IBM i partition cannot consistently boot from the DVD drive using D-mode IPL.  A SRC C2004130 may be logged for the load source not found error.
  • Support for the IBM PCIe3 12GB cache RAID plus SAS dual 4-port 6Gb x8 adapter with feature code #EJ14 and CCIN 57B1.  This adapter is very similar to the #EJ0L SAS adapter, but it uses a second chip in the card to provide more IOPS capacity (significant performance improvement) and can attach more SSD.  This adapter uses integrated flash memory to provide protection of the write cache, without need for batteries, in case of power failure.
  • Support for PowerVM vNIC extended to Linux OS Ubuntu 16.04 LE with up to ten vNIC client adapters for each partition.  PowerVM vNIC combines many of the best features of SR-IOV and PowerVM SEA to provide a network solution with options for advanced functions such as Live Partition Mobility along with better performance and I/O efficiency when compared to PowerVM SEA.  In addition PowerVM vNIC provides users with bandwidth control (QoS) capability by leveraging SR-IOV logical ports as the physical interface to the network.
  • PowerVM CoD was enhanced to eliminate the yearly Utility CoD renewal on systems using Utility COD.  The Utility CoD usage is already monitoring to make sure systems are running within the prescribed threshold limit of unreported usage, so a yearly customer renewal is not needed to manage the Utility CoD processor usage,
  • Support was added to the DHCP client on the service processor for non-random backoff mode needed for Data Center Manageability Interface (DCMI) V1.5  compliance.  By default, the DHCP client does random backoff delays for retries during DHCP discovery.  For DCMI V1.5, non-random backoff delays were introduced as an option.  Disabling the random back-off mode is not required for normal operations, but if wanted, the system administrator can override the default and disable the random back-off mode by sending the “SET DCMI Configuration Parameters” for the random back-off property of the Discovery Configuration parameter.  A value of "0" for the bit means "Disabled".  Or, the DHCP configuration file can be modified to add "random-backoff off", causing the non-random mode for the retry delays to be used during DHCP discovery.
  • Support was added for enhanced diagnostics for PowerVM Simplified Remote Restart (SRR) partitions.   This service pack level is recommended when using SRR partitions.  You can learn more about SSR partitions at the IBM Knowledge Center: " http://www.ibm.com/support/knowledgecenter/HW4P4/p8hat/p8hat_createremotereslpar.htm".
  • Support was added for auto-correction in the Advanced System Manager Interface (ASMI) for the "Feature Code/Sequence Number" field of the "System Configuration/Program Vital Product Data/System Enclosures" menu selection.  Lower case letters are invalid in the "Feature Code/Sequence Number" field so these are now changed to upper case letters to help form a valid entry.  For example, if  "78c9-001" was entered, it would be changed to "78C9-001".
  • Support was added for HTTP Strict Transport Security (HSTS) compliance for The Advanced System Management Interface (ASMI) web connection.  Even without this feature, any attempt to access ASMI with the HTTP protocol was rejected because the service processor firewall blocks port 80 (HTTP).  But enabling HSTS for ASMI prevents HSTS security warnings for the service processor during network scans by security scanner programs such as IBM AppScan.

System firmware changes that affect all systems

  • DEFERRED:  A problem was fixed in the dynamic ram (DRAM) initialization to update the VREF on the dimms to the optimal settings and to add an additional margin check test to improve the reliability of the DRAM by screening out more marginal dimms before they can result in a run-time memory fault.
  • A problem was fixed for a degraded PCI link causing a processor core to be guarded if a non-cacheable unit (NCU) store time-out occurred with SRC B113E540 and PRD signature  "(NCUFIR[9]) STORE_TIMEOUT: Store timed out on PB".  With the fix, the processor core is not guarded because of the NCU error.  If this problem occurs and a core is deconfigured. clear the guard record and re-IPL to regain the processor core.  The solution for degraded PCI links is different from the fix for this problem, but a re-IPL of the CEC or a reset of the PCI adapters could help to recover the PCI links from their degraded mode.
  • A problem was fixed for an incorrect reduction in FRU callouts for Processor Run-time Diagnostic (PRD) errors after a reference oscillator clock (OSCC) error has been logged.  Hardware resources are not called out and guarded as expected.  Some of the missing PRD data can be found in the secondary SRC of B181BAF5 logged by hardware services.  The callouts that PRD would have made are in the user data of that error log.
  • A problem was fixed for a Qualys network scan for security vulnerabilities causing a core dump in the Intelligent Platform Management Interface (IPMI)  process on the service processor with SRC B181EF88.  The error occurs anytime the Qualys scan is run because it sends an invalid IPMI session id that should have been handled and discarded without a core dump.
  • A security problem was fixed in OpenSSL for a possible service processor reset on a null pointer de-reference during RSA PPS signature verification. The Common Vulnerabilities and Exposures issue number is CVE-2015-3194.
  • A security problem was fixed in the lighttpd server on the service processor, where a remote attacker, while attempting authentication, could insert strings into the lighttpd server log file.  Under normal operations on the service processor, this does not impact anything because the log is disabled by default.  The Common Vulnerabilities and Exposures issue number is CVE-2015-3200.
  • Support for cable validation option in the Advanced System Management Interface (ASMI).  A new panel option called "Cable Validation" has been added to the "System Service Aids" menu.  The cable validation can be performed on the FSP, Clock, UPIC, and SMP cables.
  • A problem was fixed for a missing error log when a clock card fails over to the backup clock card.  This problem causes loss of redundancy on the clock cards without a callout notification that there is a problem with the FRU.  If the fix is applied to a system that had a failed clock, that condition will not be known until the system is IPLed again when a errorlog and callout of the clock card will occur if it is in a persisted failed state.
  • A problem was fixed for the Hardware Management Console (HMC) "chpwrmgmt" command not providing a meaningful error message when used to try enable an invalid power saver mode of "dynamic_favor_power" on the 9119-MME or 9119-MHE models.  This power saver mode is not available on these models but the error message issued was "HSCL1400 An error has occurred during the operation to the managed system. Try the task again."  The following is the corrected error message:  "HSCL1402 This operation failed due to the following reasons: HSCL02F3 The managed system does not support the specified power saver mode."
  • A problem was fixed for a secondary clock card (CCIN 6B49 ) failure on the system control unit (SCU) being called out as a local clock card (CCIN 6B2D) failure on the node with SRC B158E504.  For this failure to occur, the primary clock card on the SCU must have been previously failed and guarded.
  • Support was added for additional First Failure Data Capture (FFDC) data for processor clock failover errors provided by creating daily clock status reports with SRC B150CCDA informational error logs.  This clock status SRC log is written into the Hardware Management Console (HMC) iqyylog.log as a platform error log (PEL) event.  The PEL event contains a dump of the clock registers.  If a processor clock fail over with SRC B158CC62 occurs on the service processor, the iqyylog.log file on the HMC should be collected to help debug the clock problem using the B150CCDA data.
  • A problem was fixed for the service processor going to the reset state instead of the termination state when the anchor card is missing or broken.  At the termination state, the Advanced System Manager Interface (ASMI) can be used to collect failure data and debug the problem with the anchor card.
  • A problem was fixed for error log entries created by Hostboot not getting written to the error log in some situations.  This can cause hardware detected as failed by Hostboot to not get reported or have a call-home generated.  This problem will occur whenever Hostboot commits a recovered or informational error as its last error log in the current IPL.  In the next IPL,  one or more error logs from Hostboot will be lost.
  • A problem was fixed for a service processor failure during a system power off that causes a reset of the service processor.  The service processor is in the correct state for a normal system power on after the error.  The frequency for this error should be low as it is caused by a very rare race condition in the power off process.
  • A problem was fixed so that service processor NVRAM bit flips are now detected and reported as predictive errors after a certain threshold of failures have occurred.  The SRCs reported are B151F109 (threshold of NVRAM errors was reached) or B151F10A (a NVRAM address has failed multiple times).  Previously, these normal wear errors in the NVRAM were ignored.  The bit flip is self-corrected and does not cause a problem but a high occurrence of these could mean that a service processor card FRU or system backplane FRU, as called out in the SRC, is in need of service. 
  • A security problem was fixed in OpenSSL for a possible service processor reset on a null pointer de-reference during SSL certificate management. The Common Vulnerabilities and Exposures issue number is CVE-2016-0797.

System firmware changes that affect certain systems

  • DEFERRED:  On systems using PowerVM firmware, a performance improvement was made by disabling the Hot/Cold Affinity (HCA) hardware feature, which gathers memory usage statistics for consumption by partition operating system memory management algorithms.  The statistics gathering can, in rare cases, cause performance to degrade.  The workloads that may experience issues are memory-intensive workloads that have little locality of reference and thus cannot take advantage of hardware memory cache.  As a consequence, the problem occurs very infrequently or not at all except for very specific workloads in a HPC environment.  This performance fix requires an IPL of the system to activate it after it is applied.
  • DEFERRED:  On systems using 256GB DDR4 dimms, a problem was fixed in the 3DS packaging that could result in a recoverable memory error.  This fix requires an IPL of the system to take effect.  Any system with DDR4 dimms should be re-IPLed at the next opportunity to do so after applying this service pack to provide the best running conditions for the DDR4 dimms for reliable operation.
  • On systems with DDR4 memory DIMMs install, a fix was made for the longer IPL times needed to initialize DDR4 memory.  The time needed for the IPL has been reduced to be comparable to systems using other DIMM types such as DDR3.
  • On systems with a PowerVM Active Memory Sharing (AMS) partition with AIX  Level 7.2.0.0 or later with Firmware Assisted Dump enabled, a problem was fixed for a Restart Dump operation failing into KDB mode.  If "q" is entered to exit from KDB mode, the partition fails to start.  The AIX partition must be powered off and back on to recover.  The problem can be circumvented by disabling Firmware Assisted Dump (default is enabled in AIX 7.2).
  • On a PowerVM system, a problem was fixed for an incorrect date in partitions created with a Simplified Remote Restart-Capable (SRR) attribute where the date is created as Epoch 01/01/1970 (MM/DD/YYYY).  Without the fix, the user must change the partition time of day when starting the partition for the first time to make it correct.  This problem only occurs with SRR partitions.
  • On a PowerVM system with licensed Power Integrated Facility for Linux (IFL) processors, a problem was fixed for a system hang that could occur if the system contains both 1) dedicated processor partitions configured to share processors while active and  2) shared processor partitions.  This problem is more likely to occur on a system with a low number of non-IFL processors.
  • On systems using PowerVM firmware with dedicated processor partitions,  a problem was fixed for the dedicated processor partition becoming intermittently unresponsive. The problem can be circumvented by changing the partition to use shared processors.  This is a follow-on to the fix provided in 840.11 for a different issue for delays in dedicated processor partitions that were caused by low I/O utilization.
  • A problem was fixed for transmit time-outs on a Virtual Function (VF) during stressful network traffic, on systems using PCIe adapters in Single Root I/O Virtualization (SR-IOV) shared-mode.  This fix updates adapter firmware to 10.2.252.1918, for the following Feature Codes: EN15, EN16, EN17, EN18, EN0H, EN0J, EL38, EN0M, EN0N, EN0K, EN0L, and EL3C.
    The SR-IOV adapter firmware level update for the shared-mode adapters happens under user control to prevent unexpected temporary outages on the adapters.  A system reboot will update all SR-IOV shared-mode adapters with the new firmware level.  In addition, when an adapter is first set to SR-IOV shared mode, the adapter firmware is updated to the latest level available with the system firmware (and it is also updated automatically during maintenance operations, such as when the adapter is stopped or replaced).  And lastly, selective manual updates of the SR-IOV adapters can be performed using the Hardware Management Console (HMC).  To selectively update the adapter firmware, follow the steps given at the IBM Knowledge Center for using HMC to make the updates:   https://www.ibm.com/support/knowledgecenter/HW4M4/p8efd/p8efd_updating_sriov_firmware.htm.
    Note:  Adapters that are capable of running in SR-IOV mode, but are currently running in dedicated mode and assigned to a partition, can only be updated concurrently by the OS that owns the adapter.
  • On PowerVM systems using Elastic Capacity on Demand (CoD) (also known as On/Off CoD), a problem was fixed for losing entitlement amounts when upgrading from FW820 or FW830.  If you upgrade to a service pack level that does not have this fix and lose the entitlement, you can get another On/Off (Elastic) CoD Enablement code from IBM Support.  This problem only pertains to the E850 (8408-E8E), E870 (9119-MME), and E880 (9119-MHE) models.

  • The default setting for the "Enlarged I/O Memory Capacity" feature was disabled on newly manufactured E850, E870 & E880 models to reduce hypervisor memory usage.  Customers of the new systems using PCI adapters that leverage "Enlarged I/O Memory Capacity" will need to explicitly enable this feature for the supported PCI slots, using ASMI Menus while the system is powered off.  Existing systems will not see a change in their current setting.  For existing systems with only AIX and IBM i partitions that do not benefit from this feature, it can be disabled by using the Advanced System Management Interface (ASMI) for the "System Configuration-> I/O Adapter Enlarged Capacity" panel to uncheck the option for the "I/O Adapter Enlarged Adapter Capacity" feature.

System firmware changes that affect certain systems

  • On systems using PowerVM partitions, a problem was fixed for error recovery from failed Live Partition Mobility (LPM) migrations.  The recovery error is caused by a partition reset that leaves the partition in an unclean state with the following consequences:  1) A retry on the migration for the failed source partition may not not be allowed; and 2) With enough failed migration recovery errors, it is possible that any new migration attempts for any partition will be denied.  This error condition can be cleared by a re-IPL of the system. The partition recovery error after a failed migration  is much more likely to occur for partitions managed by NovaLink but it is still possible to occur for Hardware Management Console (HMC) managed partitions.

Impact:  Availability      Severity:  SPE

New features and functions

  • Support for a 256GB DDR4 memory DIMM.  Memory feature code #EM8Y provides a total of 1024GB of memory with 4 each 256GB CDIMMs (1600 MHz, 4GBIT DDR4).   Note that DDR4 and DDR3 DIMMs cannot be mixed in a drawer.
  • Support was added to block a full Hardware Management Console (HMC) connection to the service processor when the HMC is at a lower firmware major and minor release level than the service processor.  In the past, this check was done only for the major version of the firmware release but it now has been extended to the minor release version level as well.  The HMC at the lower firmware level can still make a limited connection to the higher firmware level service processor.  This will put the CEC in a "Version Mismatch" state.  Firmware updates are allowed with the CEC in the "Version Mismatch" state so that the condition can be corrected with either a HMC update or a firmware update of the CEC.
  • Support for PowerVM vNIC with more vNIC client adapters for each partition, up to 10 from a limit of 6 at the FW840.00 level.  PowerVM vNIC combines many of the best features of SR-IOV and PowerVM SEA to provide a network solution with options for advanced functions such as Live Partition Mobility along with better performance and I/O efficiency when compared to PowerVM SEA.  In addition PowerVM vNIC provides users with bandwidth control (QoS) capability by leveraging SR-IOV logical ports as the physical interface to the network.
  • Support for a 10-core 4.19 GHz Power8 processor with feature code #EPBS on the IBM Power System E880 (9119-MHE).  This feature provides a 40-core processor planar containing four ten-core processor SCMs.  Each processor core has 512KB of L2 cache and 8MB of L3 cache.
  • The default setting for the "Enlarged I/O Memory Capacity" feature was disabled on newly manufactured E850, E870 & E880 models to reduce hypervisor memory usage.  Customers using PCI adapters that leverage "Enlarged I/O Memory Capacity" will need to explicitly enable this feature for the supported PCI slots, using ASMI Menus while the system is powered off.

System firmware changes that affect all systems

  • On multi-node systems with a power fault, a problem was fix for On-Chip Controller errors caused by the power fault being reported as predictive errors for SRC B1602ACB.  These have been corrected to be informational error logs.  If running without the fix, the predictive and unrecoverable errors logged for the OCC on loss of power to the node can be ignored.
  • A problem was fixed for a system IPL hang at C100C1B0 with SRC 1100D001 when the power supplies have failed to supply the necessary 12-volt output for the system.   The 1100D001 SRC was calling out the planar when it should have called out the power supplies.  With the fix, the system will terminate as needed and call out the power supply for replacement.  One mode of power supply failure that could trigger the hang is sync-FET failures that disrupt the 12-volt output.
  • A problem was fixed for a PCIe3 I/O expansion drawer (#EMX0) not getting all error logs reported when its error log queue is full.  In the case where the error log queue is full with 16 entries, only one entry is returned to the hypervisor for reporting.  This error log truncation only occurs during periods of high error activity in the expansion drawer.
  • A problem was fixed for the callout of a VPD collection fault and system termination with SRC 11008402 to include the 1.2vcs VRM FRU.  The power good fault fault for the 1.2 volts would be a primary cause of this error.  Without the fix, the VRM is missing in the callout list and only has the VPDPART isolation procedure.
  • A problem was fixed for excessive logging of the SRC 11002610 on a power good (pgood) fault when detected by the Digital Power Subsystem Sweep (DPSS).  Multiple pgood interrupts are signaled by the DPSS in the interval between the first pgood failure and the node power down.  A threshold was added to limit the number of error logs for the condition.
  • A problem was fixed for redundant logging of the SRC B1504804 for a fan failure, once every five seconds.  With the fix, the failure is logged only at the initial time of failure in the IPL.
  • A problem was fixed to speed recovery for VPD collection time-out errors for PCIe resources in an I/O drawer logged with SRC 10009133 during concurrent firmware updates.  With the fix, the hypervisor is notified as soon as the VPD collection has finished so the PCIe resources can report as available .  Without the fix, there is a delay as long as two hours for the recovery to complete.
  • A problem was fixed to allow IPMI entity IDs to be used in ipmitool raw commands on the service processor to get the temperature reading.  Without the fix, the DCMI entity IDs have to be used in the raw command for the "Get temperature" function.
  • A problem was fixed for a false unrecoverable error (UE) logged for B1822713 when an invalid cooling zone is found during the adjustment of the system fan speeds.  This error can be ignored as it does not represent a problem with the fans.
  • A problem was fixed for a processor clock failover error with SRC B158CC62 calling out all processors instead of isolating to the suspect processor.  The callout priority correctly has a clock and a procedure callout as the highest priority, and these should be performed first to resolve the problem before moving on to the processors.
  • A problem was fixed for loss of back-level protection during firmware updates if an anchor card has been replaced.  The Power system manufacturing process sets the minimum code level a system is allowed to have for proper operation.  If a anchor card is replaced, it is possible that the replacement anchor card is one that has the Minimum MIF Level (MinMifLevel) given as "blank",  and this removes the system back-level protection. With the fix, blanks or nulls on the anchor card for this field are handled correctly to preserve the back-level protection.  Systems that have already lost the back-level protection due to anchor card replacement remain vulnerable to a accidental downgrade of code level by operator error, so code updates to a lower level for these systems should only be performed under guidance from IBM Support.  The following command can be run the Advanced Management Management Interface (ASMI) to determine if the system has lost the back-level protection with the presence of "blanks" or ASCII 20 values for MinMifLevel:
    "registry -l cupd/MinMifLevel" with output:
    "cupd/MinMifLevel:
    2020202020202020 2020202020202020 [ ]
    2020202020202020 2020202020202020 [ ]"
  • A problem was fixed for a code update error from FW830 to a FW840 level causes temperature sensors to be lost so that the ipmitool command to list the temperature sensors fails with a IPMI program core dump.  If the temperature sensors are already corrupted due to a preceding code update, this fix adds back in the temperature sensors to allow the ipmitool to work for listing the temperature sensors.
  • A problem was fixed for a system checkstop caused by a L2 cache least-recently used (LRU) error that should have been a recoverable error for the processor and the cache.  The cache error should not have caused a L2 HW CTL error checkstop.
  • A problem was fixed for a re-IPL with power on failure with B181A40F SRC logged for VPD not found for a DIMM FRU.  The DIMM had been moved to another slot or just removed.  In this situation, a IPL of the system from power off will work without errors, but a re-IPL with power on,  such as that done after processing a hardware dump, will fail with the B181A40F.  Power off the system and IPL to recover.  Until the fix is applied, the problem can be circumvented after a DIMM memory move by putting the PNOR flash memory in genesis mode by running the following commands in ASMI with the CEC powered off:
            1) hwsvPnorCmd -c
            2) hwsvPnorCmd -g
  • A problem was fixed for the service processor becoming inaccessible when having a dynamic IP address and being in DCMI "non-random" mode for DHCP discovery by customer configuration.  The problem can occur intermittently during a AC power on of the system.  If the service processor does not respond on the network, AC power cycle to recover.  Without the fix, the problem can be circumvented by using the DHCP client in the DCMI "random" mode for DHCP discovery, which is the default on the service processor.
  • A problem was fixed for priority callouts for system clock card errors with SRC B158CC62.  These errors had high priority callouts for the system clock card and medium callouts for FRUs in the clock path.  With the fix, all callouts are set to medium priority as the clock card is not the most probable FRU to have failed but is just a candidate among the many FRUs along the clock path.
  • A problem was fixed for a memory initialization error reported with SRC BC8A0506 that terminates the IPL.  This problem is unlikely to occur because it depends on a specific memory location being used by the code load. The system can be recovered from the error by doing another IPL.

System firmware changes that affect certain systems

  • On PowerVM systems a problem was fixed to address a performance degradation. The problem surfaces under the following conditions:
    1)    There is at least one VIOS or Linux partition that is running with dedicated processors AND
    2)    There is at least one VIOS or Linux partition running with shared processors AND
    3)    There is at least one AIX or IBMi partitions configured with shared processors. 
    If ALL the above conditions are met AND one of the following actions occur,
    1)    VIOS/Linux dedicated processor partition is configured to share processors while active OR
    2)    A dynamic platform optimization operation (HMC 'optmem' command) is performed OR
    3)    Processors are unlicensed via a capacity on demand operation
    there is an exposure for a loss in performance.
  • On systems using PowerVM firmware, a problem was fixed for PCIe switch recovery to prevent a partition switch failure during the IPL with error logs for SRC B7006A22 and B7006971  reported.  This problem can occur when doing recovery for an informational error on the switch.  If this problem occurs, the partition must be restarted to recover the affected I/O adapters.
  • On systems using PowerVM firmware, a problem was fixed for a concurrent FRU exchange of a CAPI  (Coherent Accelerator Processor Interface) adapter for a standard I/O adapter that results in a vary off failure.  If this failure occurs, the system needs to be re-IPLed to fix the adapter.  The trigger for this failure is a dual exchange where the CAPI adapter is exchanged first for a standard (non-like-typed) adapter.  Then an attempt is made to exchange the standard adapter for a CAPI adapter which fails.
  • On systems using PowerVM firmware, a problem was fixed for a CAPI  (Coherent Accelerator Processor Interface) device going to a "Defined" state instead of "Available" after a partition boot.  If the CAPI device is doing recovery and logging error data at the time of the partition boot, the error may occur.  To recover from the error, reboot the partition.  With the fix, the hypervisor will wait for the logging of error data from the CAPI device to finish before proceeding with the partition boot.
  • On systems using PowerVM firmware, a problem was fixed for a hypervisor adjunct partition failed with "SRC B2009008 LP=32770" for an unexpected SR-IOV adapter configuration.  Without the fix, the system must be re-IPLed to correct the adjunct error.  This error is infrequent and can only occur if an adapter port configuration is being changed at the same time that error recovery is occurring for the adapter.
  • On systems using PowerVM firmware and PCIe adapters in SR-IOV mode,  the following problem was addressed with a Broadcom Limited (formerly known as Avago Technologies and Emulex) adapter firmware update to 10.2.252.1913:  Transmit time-outs on a Virtual Function (VF) during stressful network traffic.
  • On systems using PowerVM firmware with an invalid P-side or T-side in the firmware, a problem was fixed in the partition firmware Real-Time Abstraction System (RTAS) so that system Vital Product Data (VPD) is returned at least from the valid side instead of returning no VPD data.   This allows AIX host commands such as lsmcode, lsvpd, and lsattr that rely on the VPD data to work to some extent even if there is one bad code side.  Without the fix,  all the VPD data is blocked from the OS until the invalid code side is recovered by either rejecting the firmware update or attempting to update the system firmware again.
  • On systems using PowerVM firmware without a HMC (and in Manufacturing Default Configuration (MDC) mode with a single host partition), a problem was fixed for missing dumps of type SYSDUMP. FSPDUMP. LOGDUMP, and RSCDUMP that were not off-loaded to the host OS.  This is an infrequent error caused by a timing error that causes the dump notification signal to the host OS to be lost.  The missing/pending dumps can be retrieved by rebooting the host OS partition.  The rebooted host OS will receive new notifications of the dumps that have to be off-loaded.
  • On systems using PowerVM firmware, a problem was fixed for truncation on the memory fields displayed in the Advanced System Management Interface on the COD panels.  ASMI shows three fields of memory called "Installed memory", Permanent memory", and "Inactive memory".  The largest value that can be displayed in the fields was "9999" GB.  This has been expanded to a maximum of "999999" GB for each of the ASMI fields.  The truncation was only in the displayed memory value, not in the actual memory size being used by the system which was correct.
  • On systems using PowerVM firmware and a partition using Active memory Sharing (AMS), a problem was fixed for a Live Partition Mobility (LPM) migration of the AMS partition that can hang the hypervisor on the target CEC.  When an AMS partition migrates to the target CEC, a hang condition can occur after processors are resumed on the target CEC, but before the migration operation completes.  The hang will prevent the migration from completing, and will likely require a CEC reboot to recover the hung processors.  For this problem to occur, there needs to be memory page-based activity (e.g. AMS dedup or Pool paging) that occurs exactly at the same time that the Dirty Page Manager's PSR data for that page is being sent to the target CEC.
  • On systems using PowerVM firmware and having a IBM i partition with more than 64 cores, a performance problem was fixed with the choice of processor cores assigned to the partition.
    This problem only applies to the E870 (9119-MME) and E880 (9119-MHE) models.
  • On systems using PowerVM firmware, a problem was fixed for PCIe adapter hangs and network traffic error recovery during Live Partition Mobility (LPM) and SR-IOV vNIC (virtual ethernet adapter)  operations.  An error in the PCI Host Bridge (PHB) hardware can persist in the L3 cache and fail all subsequent network traffic through the PHB.  The PHB  error recovery was enhanced to flush the PHB L3 cache to allow network traffic to resume.
  • On systems using PowerVM firmware with AIX or Linux partitions with greater than 8TB of memory, a problem was fixed for Dynamic DMA Window (DDW) enabled adapters IPLing into a "Defined" state,  instead of "Available", and unusable with a "0" size DMA window.  If a DDW enabled adapter is plugged into an HDDW (Huge Dynamic DMA Window) slot in a partition with the large memory size, the OS changes the default DMA window to "0" in size.  To prevent this problem, the Advanced System Management Interface (ASMI) in the service processor can be used to set "I/O Enlarged Capacity" to "0" (which is off), and all the DDW enabled adapters will work on the next IPL.
  • On a multi-node system,  a problem was fixed for a power fault with SRC 11002610 having incorrect FRU callouts.  The wrong second FRU callout is made on nodes 2, 3, and 4 of a multi-node system.  Instead of calling out the processor FRU, the enclosure FRU is called out.  The first FRU callout is correct.
  • On PowerVM systems with partitions running Linux, a problem was fixed for intermittent hangs following a Live Partition Mobility (LPM) migration of a Linux partition.  A partition migrating from a source system running FW840.00 to a system running any other supported firmware level may become unresponsive and unusable once it arrives on the target system.  The problem only affects Linux partitions and is intermittent.  Only partitions that have previously been migrated to a FW840.00 system are susceptible to a hang on subsequent migration to another system.  If a partition is hung following a LPM migration, it must be rebooted on the target system to resume operations.
  • On systems using OPAL firmware, a problem was fixed that prevented multiple NVIDIA Tesla K80 GPUs from being attached to one PCIe adapter.  This prevented using a PCIe attached GPU drawer.  This fix increases the PCIe MMIO (memory-mapped I/O) space to 1 TB from a previous maximum of 64 GB per PHB/PCIe slot.
  • On PowerVM systems with dedicated processor partitions with low I/O utilization, the dedicated processor partition may become intermittently unresponsive. The problem can be circumvented by changing the partition to use shared processors.
  • On systems using OPAL firmware, a problem was fixed in OPAL to identify the PCI Host Bridge (PHB) on CAPI adapter errors and not always assume PHB0.
  • On systems using OPAL firmware, a problem was fixed in the OPAL gard utility to remove gard records after guarded components have been replaced,  Without the fix, Hostboot and the gard utility could be in disagreement on the replaced components, causing some components to still display as guarded after a repair.
  • On systems using PowerVM firmware with partitions with very large number of PCIe adapters, a problem was fixed for partitions that would hang because the partition firmware ran out of memory for the OpenFirmware FCode device drivers for PCIe adapters.  With the fix, the hypervisor is able to dynamically increase the memory to accommodate the larger partition configurations of I/O slots and adapters.
  • On PowerVM systems with vNIC adapters, a problem was fixed for doing a network boot or install from the adapter using a VLAN tag.  Without the fix, the support is missing for doing a network boot from the VLAN tag from the SMS RIPL menu.
  • On systems using PowerVM firmware, a problem was fixed for a Live Partition Mobility (LPM) migration of a partition with large memory that had a migration abort when the partition took longer than five minutes to suspend.  This is a rare problem and is triggered by an abnormally slow response time from the migrating partition.  With the fix, the five minute time limit on the suspend operation has been removed.

New Features and Functions

NOTE:
  • POWER8 (and later) servers include an “update access key” that is checked when system firmware updates are applied to the system.  The initial update access keys include an expiration date which is tied to the product warranty. System firmware updates will not be processed if the GA date of the desired firmware level occurred after the update access key’s expiration date.  As these update access keys expire, they need to be replaced using either the Hardware Management Console (HMC) or the Advanced Management Interface (ASMI) on the service processor.  Update access keys can be obtained via the key management website: http://www.ibm.com/servers/eserver/ess/index.wss.
  • Support for allowing the PowerVM hypervisor to continue to run when communication between the service processor and platform firmware has been lost and cannot be re-established.  A SRC B1817212 may be logged and any active partitions will continue to run but they will not be able to be managed by the management console.  The partitions can be allowed to run until the next scheduled service window at which time the service processor can be recovered with an AC power cycle or a pin-hole reset from the operator panel.  This error condition would only be seen on a system that had been running with a single service processor (no redundancy for the service processor).
  • Support in the Advanced Systems Management Interface (ASMI) for managing certificates on the service processor with option "System Configuration/Security/Certificate Management".  Certificate management includes 1) Generation of Certificate Signing Request (CSR) 2) Download of CSR and 3) Upload of signed certificates.  For more information on managing certificates, go to the IBM KnowledgeCenter link for "Certificate Management"
    (https://www-01.ibm.com/support/knowledgecenter/P8ESS/p8hby/p8hby_securitycertificate.htm)
  • Support for concurrent add of the PCIe expansion drawer (F/C #EMX0) and concurrent add of PCIe optical cable adapters (F/C EJ07 and CCIN 6B52).  For concurrent add guidance, go to the IBM KnowledgeCenter links for "Connecting a PCIe Gen3 I/O expansion drawer to your system"(https://www-01.ibm.com/support/knowledgecenter/9119-MHE/p8egp/p8egp_connect_kickoff.htm?lang=en-us) and for  "PCIe adapters for the 9119-MHE and 9119-MME" (https://www-01.ibm.com/support/knowledgecenter/9119-MHE/p8hak/p8hak_87x_88x_kickoff.htm?lang=en-us).
  • Support for concurrent repair/exchange of the PCIe3 6-slot Fanout module for the PCIe3 Expansion Drawer,  PCIe Optical Cable adapters and PCIe3 Optical Cable.  For concurrent repair/exchange guidance for these parts, go to the IBM KnowledgeCenter link for "Removing and replacing parts in the PCIe Gen3 I/O expansion drawer"(https://www-01.ibm.com/support/knowledgecenter/9119-MHE/p8egr/p8egr_emx0_kickoff.htm?lang=en-us). Below are the feature codes for the affected parts:
    #EMX0 - PCIe3 Expansion Drawer
    #EMXF - PCIe3 6-Slot Fanout Module for PCIe3 Expansion Drawer (all server models)
    #EJ07 (CCIN 6B52) - PCIe3 Optical Cable Adapter for PCIe3 Expansion Drawer
    #ECC6 - 2M Optical Cable Pair for PCIe3 Expansion Drawer
    #ECC8 - 10M Optical Cable Pair for PCIe3 Expansion Drawer
    #ECC9 - 20M Optical Cable Pair for PCIe3 Expansion Drawer
  • PowerVM support for Support for Coherent Accelerator Processor Interface (CAPI) adapters.  The PCIe3 LP CAPI Accelerator Adapter with F/C #EJ16 is used on the S812L(8247-21L) and S822L (8247-22L)  models  The PCIe3 CAPI FlashSystem Acclerator Adapter with F/C #EJ17  is used on the S814(8286-41A) and S824(8286-42A) models.  The PCIe3 CAPI FlashSystem Accelerator Adapter with F/C #EJ18 is used on the S822(8284-22A), E870(9119-MME), and E880(9119-MHE) models.  This feature does not apply to the S824L (8247-42L) model.
  • Management console enhancements for support of concurrent maintenance of CAPI-enabled adapters.
  • Support for PCIe3 Expansion Drawer (#EMX0) lower cable failover, using lane reversal mode to bring up the expansion drawer from the top cable.  This eliminates a single point of failure by supporting lane reversal in case of problems with the lower cable.
  • Expanded support of Virtual Ethernet Large send from IPv4 to the IPv6 protocol in PowerVM.
  • Support for IBM i network install on a IEEE 802.1Q VLAN.  The OS supported levels are IBM i.7.2.TR3 or later.  This feature applies only to S814 (8286-41A), S824(8286-42A), E870 (9119-MME), and E880 (9119-MHE) models.
  • Support for PowerVM vNIC with up to six vNIC client adapters for each partition.  PowerVM vNIC combines many of the best features of SR-IOV and PowerVM SEA to provide a network solution with options for advanced functions such as Live Partition Mobility along with better performance and I/O efficiency when compared to PowerVM SEA.  In addition PowerVM vNIC provides users with bandwidth control (QoS) capability by leveraging SR-IOV logical ports as the physical interface to the network.
    Note:  If more than six vNIC client adapters are used in a partition, the partition will run, as there is no check to prevent the extra adapters, but certain operations such as Live Partition Mobility may fail.
  • Enhanced handling of errors to allow partial data in a Shared Storage Pool (SSP) cluster.  Under partial data error conditions, the management console "Manage PowerVM" gui will correctly show the working VIOS clusters along with information about the broken VIOS clusters, instead of showing no data.
  • Live Partition Mobility (LPM) was enhanced to allow the user to specify VIOS concurrency level overrides.
  • Support was added for PowerVM hard compliance enforcement of the Power Integrated Facility for Linux (IFL).  IFL is an optional lower cost per processor core activation for Linux-only workloads on IBM Power Systems.  Power IFL processor cores can be activated that are restricted to running Linux workloads.  In contrast, processor cores that are activated for general-purpose workloads can run any supported operating system.  PowerVM  will block partition activation, LPM and DLPAR requests on a system with IFL processors configured if the total entitlement of AIX and IBMi partitions exceeds the amount of licensed general-purpose processors.  For AIX and IBMi partitions configured with uncapped processors, the PowerVM hypervisor will limit the entitlement and uncapped resources consumed to the amount of expensive processors that are currently licensed.
  • Support was added to allow Power Enterprise Pools to convert permanently-licensed (static) processors to Pool Processors using a CPOD COD activation code provided by the management console.  Previously, only unlicensed processors were able to become Pool Processors.
  • The management console was enhanced to allow a Live Partition Mobility (LPM) if there is a failed VIOS in a redundant pair.  During LPM, if the VIOS is inactive, the management console will use stored configuration information to perform the LPM.
  • The firmware update process from the management console and from in-band OS (except for IBM i PTFs) has been enhanced to download new "Update access keys" as needed to prevent the access key from expiring.  This provides an automatic renewal process for the entitled customer.
  • Live Partition Mobility support was added to allow the user to specify a different virtual Ethernet switch on the target server.
  • PowerVM was enhanced to support an AIX Live Update where the AIX kernel is updated without rebooting the kernel.  The AIX OS level must be 7.2 or later.  Starting with AIX Version 7.2, the AIX operating system provides the AIX Live Update function which eliminates downtime associated with patching the AIX operating system. Previous releases of AIX
    required systems to be rebooted after an interim fix was applied to a running system. This new feature allows workloads to remain active during a Live Update operation and the operating system
    can use the interim fix immediately without needing to restart the entire system. In the first release of this feature, AIX Live Update will allow customers to install interim fixes (ifixes) only. For more information on AIX Live Update,  go to the IBM KnowledgeCenter link for "Live Update" 
    (https://www-01.ibm.com/support/knowledgecenter//ssw_aix_72/com.ibm.aix.install/live_update_install.htm).
  • The management console has been enhanced to use standard FTP in its firmware update process instead of a custom implementation.  This will provide a more consistent interface for the users.
  • Support for setting Power Management Tuning Parameters from the management console (Fixed Maximum Frequency (FMF), Idle Power Save, and DPS Tunables) without needing to use the Advanced System Management Interface (ASMI) on the service processor.  This allows FMF mode to be set by default without having to modify any tunable parameters using ASMI.
  • Support for a Corsa PCIe adapter with accelerator FPGA for low latency connection using CAPI (Coherent Accelerator Processor Interface) attached to a FlashSystem 900 using two 8Gb optical SR Fibre Channel (FC) connections.
    Supported IBM Power Systems for this feature are the following:
    1) E880 (9119-MHE) with CAPI Activation feature #EC19 and  Corsa adapter #EJ18 Low profile on AIX.
    2) E870 (9119-MME) with CAPI Activation feature #EC18 and Corsa adapter #EJ18.Low profile on AIX.
    3) S822 (8284-22A) with CAPI  Activation feature #EC2A and Corsa adapter #EJ18.Low profile on AIX.
    4) S814 (8286-41A) with CAPI Activation feature #EC2A and Corsa adapter #EJ17 Full height on AIX.
    5) S824 (8286-42A) with CAPI Activation feature #EC2A and Corsa adapter #EJ17 Full height on AIX.
    6) S812L (8247-21L) with CAPI Activation feature #EC2A and Corsa adapter #EJ16 Low profile on Linux.
    7) S822L (8247-22L)  with CAPI Activation feature #EC2A and Corsa adapter #EJ16 Low profile on Linux.
    OS levels that support this feature are PowerVM AIX 7.2 or later and OPAL bare-metal Linux Ubuntu 15.10.
    The IBM FlashSystem 900 storage system is model 9840-AE2 (one year warranty) or 9843-AE2 (three year warranty) at the 1.4.0.0 or later firmware level with features codes #AF23, #AF24, and #AF25 supported for 1.2 TB, 2.9 TB, 5.7 TB modules, respectively.
  • The Digital Power Subsystem Sweep (DPSS) FPGA, used to control P8 fan speeds and memory voltages, was enhanced to support the 840 GA level. This DPSS update is delayed to the next IPL of the CEC and adds 18 to 20 minutes to the IPL.  See the "Concurrent Firmware Updates" section above for details.
  • Support for Data Center Manageability Interface (DCMI) V1.5 and Energy Star compliance.  DCMI  features were added to the Intelligent Platform Management Interface (IPMI) 2.0 implementation on the service processor.  DCMI adds platform management capability for monitoring elements such as system temperatures, power supplies, and bus errors.  It also includes automatic and manually driven recovery capabilities such as local or remote system resets, power on/off operations, logging of abnormal or  "out-of-range‟ conditions for later examination.  And It allows querying for inventory information that can help identify a failed hardware unit along with power management options for getting and setting power limits.
    Note:  A deviation from the DCMI V1.5 specification exists for 840.00 for the DCMI Configuration Parameters for DHCP Discovery.  Random back-off mode is enabled by default instead of being disabled.  The random back-off puts a random variation delay in the DHCP retry interval so that the DHCP clients are not responding at the same time. Disabling the back-off time is not required for normal operations, but if wanted, the system administrator can override the default and disable the random back-off mode by sending the “SET DCMI Configuration Parameters” for the random back-off property of the Discovery Configuration parameter.  A value of "0" for the bit means "Disabled".

4.0 How to Determine The Currently Installed Firmware Level

You can view the server's current firmware level on the Advanced System Management Interface (ASMI) Welcome pane. It appears in the top right corner. Example: SC830_123.


5.0 Downloading the Firmware Package

Follow the instructions on Fix Central. You must read and agree to the license agreement to obtain the firmware packages.

Note: If your HMC is not internet-connected you will need to download the new firmware level to a USB flash memory device or ftp server.


6.0 Installing the Firmware

The method used to install new firmware will depend on the release level of firmware which is currently installed on your server. The release level can be determined by the prefix of the new firmware's filename.

Example: SCxxx_yyy_zzz

Where xxx = release level
