1.0 Systems Affected

This package provides firmware for Power Systems L922 (9008-22L), Power System S922 (9009-22A), Power System S914 (9009-41A), Power System S924 (9009-42A), Power System H922 (9223-22H) Power System H924 (9223-42H), Power Systems S922 (9009-22G), Power Systems S914 (9009-41G), Power Systems S924 (9009-42G), IBM Power System H922 for SAP HANA  (9223-22S), IBM Power System H924 for SAP HANA  (9223-42S), and IBM ESS (5105-22E) 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 levels for this firmware for HMC x86,  ppc64 or ppc64le are listed below.


x86 -  This term is used to reference the legacy HMC that runs on x86/Intel/AMD hardware for the Virtual HMC that can run on the Intel hypervisors (KVM, XEN, VMWare ESXi).
ppc64 or ppc64le - describes the Linux code that is compiled to run on Power-based servers or LPARS (Logical Partitions)
The Minimum HMC level supports the following HMC models:
x86 - KVM, XEN, VMWare ESXi (6.0/6.5)
ppc64le - 7063-CR1,vHMC on PowerVM (POWER8 and POWER9 systems

2.0 Important Information

NovaLink issue with remote start and inactive partition migration operations

There is a known issue with remote restart and inactive partition migration operations initiated from NovaLink when the source system is running this firmware level. Remote restart and inactive partition migration functionality initiated from an HMC is not impacted by this issue.   When attempting these operations with PowerVC on a NovaLink managed environment, a PVME01040100-0004 with Internal error PVME01038003 may be encountered on the target system.  This issue is planned to be addressed in a future FW950.00 Service Pack.  Systems running with a previous firmware level should remain at that level until a FW950 Service Pack is released which addresses the issue with remote restart and inactive partition migration operations initiated from Novalink. If you have systems shipped with FW950.00 and require more immediate support for remote restart or inactive partition migration operations initiated from NovaLink, please contact IBM support.

Boot adapter microcode requirement

Update all adapters which are boot adapters, or which may be used as boot adapters in the future, to the latest microcode from IBM Fix Central.  The latest microcode will ensure the adapters support the new Firmware Secure Boot feature of Power Systems. This requirement applies when updating system firmware from a level prior to FW940 to levels FW940 and later.
The latest adapter microcode levels include signed boot driver code. If a boot-capable PCI adapter is not installed with the latest level of adapter microcode, the partition which owns the adapter will boot, but error logs with SRCs BA5400A5 or BA5400A6 will be posted.  Once the adapter(s) are updated, the error logs will no longer be posted.

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

Firmware downgrade warnings:
1) Adapter feature codes (#EC2R/#EC2S/#EC2T/#EC2U and #EC3L/#EC3M and #EC66/EC67) when configured in SR-IOV shared mode in FW930 or later, even if originally configured in shared mode in a pre-FW930 release, may not function properly if the system is downgraded to a pre-FW930 release. The adapter should be configured in dedicated mode first (i.e. take the adapter out of SR-IOV shared mode) before downgrading to a pre-FW930 release.
2) If partitions have been run in POWER9 compatibility mode in FW940, a downgrade to an earlier release (pre-FW940) may cause a problem with the partitions starting.  To prevent this problem, the "server firmware" settings must be reset by rebooting partitions in "Power9_base" before doing the downgrade.

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.

Upgrade from FW941.00 to FW950 will change the QPRCFEAT QMODEL code for the 9009-22G, 9009-41G, and 9009-42G models.

If updating from FW941.00 to FW950 for IBM i, there is a fix for incorrect QPRCFEAT QMODEL values for the 9009-xxG models.  If 3rd party software licenses were installed based on the old incorrect QPRCFEAT QMODEL value, new licenses will be needed to work with the updated value:  The QPRCFEAT QMODEL IBM System Value was showing the 9009-xxG models as 9009-xxA models.  For example, the 9009-22G reported as "EP11" instead of "EP51".  This mismatch can prevent 3rd party software licenses from working.

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 supported on HMC Managed Systems only.

Ensure that there are no RMC connections issues for any system partitions prior to applying the firmware update.  If there is a RMC connection failure to a partition during the firmware update, the RMC connection will need to be restored and additional recovery actions for that partition will be required to complete partition firmware updates.

2.3 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.

Additional information can be found at:
https://www.ibm.com/support/knowledgecenter/9009-22A/p9hat/p9hat_lparmemory.htm

2.4 SBE Updates

Power 9 servers contain SBEs (Self Boot Engines) and are used to boot the system.  SBE is internal to each of the Power 9 chips and used to "self boot" the chip.  The SBE image is persistent and is only reloaded if there is a system firmware update that contains a SBE change.  If there is a SBE change and system firmware update is concurrent, then the SBE update is delayed to the next IPL of the CEC which will cause an additional 3-5 minutes per processor chip in the system to be added on to the IPL.  If there is a SBE change and the system firmware update is disruptive, then SBE update will cause an additional 3-5 minutes per processor chip in the system to be added on to the IPL.  During the SBE update process, the HMC or op-panel will display service processor code C1C3C213 for each of the SBEs being updated.  This is a normal progress code and system boot should be not be terminated by the user. Additional time estimate can be between 6-10 minutes.

The SBE image is updated with this service pack.

2.5 NVDIMM Updates

Power 9 ESS 5010-22E servers contain NVDIMMs that may be updated with a service pack. Updating NVDIMM firmware takes approximately 8 minutes per NVDIMM on ESS I/O servers 5105-22E. If an NVDIMM firmware update is required, then this would be incurred only on the initial system boot when updating system firmware or replacing an NVDIMM. There are 4 NVDIMMs per server, so up to an additional 32 minutes might be needed to complete the system boot in these cases.

The NVDIMM firmware is updated with this service pack.

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:

01VLxxx_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, 01VL900_040_040 and 01VL910_040_045 are different service packs.

An installation is disruptive if:

            Example: Currently installed release is 01VL900_040_040, new release is 01VL910_050_050.

            Example: VL910_040_040 is disruptive, no matter what level of VL910 is currently installed on the system.

            Example: Currently installed service pack is VL910_040_040 and new service pack is VL910_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 VL910_040_040, new service pack is VL910_041_040.

  • Support for new PCIe 4.0 x8 dual-port 32 Gb optical Fibre Channel (FC) short form adapter based on the Marvell QLE2772 PCIe host bus adapter (6.6 inches x 2.731 inches). The adapter provides two ports of 32 Gb FC capability using SR optics. Each port can provide up to 6,400 MBps bandwidth. This adapter has feature codes #EN1J/#EN1K with CCIN 579C. Firmware level FW950.10 or later is required for this adapter.
  • Support for new PCIe 3.0 16 Gb quad-port optical Fibre Channel (FC)l x8 short form adapter based on the Marvell QLE2694L PCIe host bus adapter (6.6 inches x 2.371 inches). The adapter provides four ports of 16 Gb FC capability using SR optics. Each port can provide up to 3,200 MBps bandwidth. This adapter has feature codes #EN1E/#EN1F with CCIN 579A. Firmware level FW950.10 or later is required for this adapter.
  • Support for Enterprise 800 GB PCIe4 NVMe SFF U.2 15mm SSD for IBM i. The SSD can be used in any U.2 15mm NVMe slot in the system. This drive has feature code #ES1K and CCIN 5947. Firmware level FW950.10 or later is required for this drive.
  • Added support in ASMI for a new panel to do Self -Boot Engine (SBE) SEEPROM validation.  This validation can only be run at the service processor standby state.  
    If the validation detects a problem, IBM recommends the system not be used and that IBM service be called.
System firmware changes that affect all systems
  • HIPER/Pervasive: A problem was fixed for a system IPL failure when DIMMs (RDIMMs or NVDIMMs) have mixed configurations with dual populated memory channels and single populated memory channels.  This problem occurs If there are dually populated memory channels that precede a single DIMM memory channel for a processor.  This causes the IPL to fail with B150BA40 and BC8A090F logged with HwpReturnCode "RC_MSS_CALC_POWER_CURVE_NEGATIVE_OR_ZERO_SLOPE " and HWP Error description "Power curve slope equals 0 or is negative".  A workaround for this problem is to reconfigure the memory to have the single DIMM memory channels be in front of memory channels that have both DIMM slots occupied.
  • A problem was fixed for certain SR-IOV adapters that have a rare, intermittent error with B400FF02 and B400FF04 logged, causing a reboot of the VF.  The error is handled and recovered without any user intervention needed.  The SR-IOV adapters affected have the following Feature Codes and CCINs: #EC2R/#EC2S with CCIN 58FA; #EC2T/#EC2U with CCIN 58FB; #EC3L/#EC3M with CCIN 2CE; and #EC66/#EC67 with CCIN 2CF3.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for initiating a Remote Restart from a PowerVC/NovaLink source system to a remote target. This happens whenever the source system is running FW950.00. The error would look like this from PowerVC (system name, release level would be specific to the environment):
    "Virtual machine RR-5 could not be remote restarted to Ubu_AX_9.114.255.10. Error message: PowerVM API failed to complete for instance=RR-5-71f5c2cf-0000004e.HTTP error 500 for method PUT on path /rest/api/uom/ManagedSystem/598c1be4-cb4c-3957-917d-327b764d8ac1/LogicalPartition: Internal Server Error -- [PVME01040100-0004] Internal error PVME01038003 occurred while trying to perform this command.".
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for a B1502616 SRC logged after a system is powered off.  This rare error, "A critical error occurred on the thermal/power management device (TPMD); it is being disabled. " is not a real problem but occurred because the Power Management (PM) complex was being reset during the power off.  No recovery is needed as the next IPL of the system is successful.
  • A problem was fixed for the error handling of a system with an unsupported memory configuration that exceeds available memory power. Without the fix, the IPL of the system is attempted and fails with a segmentation fault with SRCs B1818611 and B181460B logged that do not call out the incorrect DIMMs.
  • A problem was fixed for an error in the HMC GUI (Error launching task) when clicking on "Hardware Virtualized IO". This error is infrequent and is triggered by an optical cable to a PCIe3 #EMX0 expansion drawer that is failed or unplugged.  With the fix, the HMC can show the working I/O adapters.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for performance degradation of a partition due to task dispatching delays. This may happen when a processor chip has all of its shared processors removed and converted to dedicated processors. This could be driven by DLPAR remove of processors or Dynamic Platform Optimization (DPO).
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for an unrecoverable UE SRC B181BE12 being logged if a service processor message acknowledgment is sent to a Hostboot instance that has already shutdown.  This is a harmless error log and it should have been marked as an informational log.
  • A problem was fixed for Time of Day (TOD) being lost for the real-time clock (RTC) with an SRC B15A3303 logged when the service processor boots or resets.  This is a very rare problem that involves a timing problem in the service processor kernel.  If the server is running when the error occurs, there will be an SRC B15A3303 logged, and the time of day on the service processor will be incorrect for up to six hours until the hypervisor synchronizes its (valid) time with the service processor.  If the server is not running when the error occurs, there will be an SRC B15A3303 logged, and If the server is subsequently IPLed without setting the date and time in ASMI to fix it, the IPL will abort with an SRC B7881201 which indicates to the system operator that the date and time are invalid.
  • A problem was fixed for the Systems Management Services ( SMS) menu "Device IO Information" option being incorrect when displaying the capacity for an NVMe or Fibre Channel (FC) NVMe disk.  This problem occurs every time the data is displayed.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for intermittent failures for a reset of a Virtual Function (VF) for SR-IOV adapters during Enhanced Error Handling (EEH) error recovery. This is triggered by EEH events at a VF level only, not at the adapter level. The error recovery fails if a data packet is received by the VF while the EEH recovery is in progress. A VF that has failed can be recovered by a partition reboot or a DLPAR remove and add of the VF.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for a logical partition activation error that can occur when trying to activate a partition when the adapter hardware for an SR-IOV logical port has been physically removed or is unavailable due to a hardware issue. This message is reported on the HMC for the activation failure:  "Error:  HSCL12B5 The operation to remove SR-IOV logical port <number> failed because of the following error: HSCL1552 The firmware operation failed with extended error" where the logical port number will vary.  This is an infrequent problem that is only an issue if the adapter hardware has been removed or another problem makes it unavailable.  The workaround for this problem is to physically add the hardware back in or correct the hardware issue.  If that cannot be done, create an alternate profile for the logical partition without the SR-IOV logical port and use that until the hardware issue is resolved.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for incomplete periodic data gathered by IBM Service for #EMXO PCIe expansion drawer predictive error analysis.  The service data is missing the PLX (PCIe switch) data that is needed for the debug of certain errors.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for a partition hang in shutdown with SRC B200F00F logged.  The trigger for the problem is an asynchronous NX accelerator job (such as gzip or NX842 compression) in the partition that fails to clean up successfully.  This is intermittent and does not cause a problem until a shutdown of the partition is attempted.  The hung partition can be recovered by performing an LPAR dump on the hung partition.  When the dump has been completed, the partition will be properly shut down and can then be restarted without any errors.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for a rare failure for an SPCN I2C command sent to a PCIe I/O expansion drawer that can occur when service data is manually collected with hypervisor macros "xmsvc -dumpCCData and xmsvc -logCCErrBuffer".   If the hypervisor macro "xmsvc "is run to gather service data and a CMC Alert occurs at the same time that requires an SPCN command to clear the alert, then the I2C commands may be improperly serialized, resulting in an SPCN I2C command failure.  To prevent this problem,  avoid using xmsvc -dumpCCData and xmsvc -logCCErrBuffer to collect service data until this fix is applied.
    This problem does not pertain to model ESS 5105-22E.
  • The following problems were fixed for certain SR-IOV adapters:
    1) An error was fixed that occurs during a VNIC failover where the VNIC backing device has a physical port down or read port errors with an SRC B400FF02 logged.
    2) A problem was fixed for adding a new logical port that has a PVID assigned that is causing traffic on that VLAN to be dropped by other interfaces on the same physical port which uses OS VLAN tagging for that same VLAN ID.  This problem occurs each time a logical port with a non-zero PVID that is the same as an existing VLAN is dynamically added to a partition or is activated as part of a partition activation, the traffic flow stops for other partitions with OS configured VLAN devices with the same VLAN ID.  This problem can be recovered by configuring an IP address on the logical port with the non-zero PVID and initiating traffic flow on this logical port.  This problem can be avoided by not configuring logical ports with a PVID if other logical ports on the same physical port are configured with OS VLAN devices.
    This fix updates the adapter firmware to 11.4.415.37 for the following Feature Codes and CCINs:  #EN15/#EN16 with CCIN 2CE3, #EN17/#EN18 with CCIN 2CE4, #EN0H/#EN0J with CCIN 2B93, #EN0M/#EN0N with CCIN 2CC0, #EN0K/#EN0L with CCIN 2CC1, #EL56/#EL38 with CCIN 2B93, and #EL57/#EL3C with CCIN 2CC1.
    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/en/POWER9/p9efd/p9efd_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 be updated concurrently either by the OS that owns the adapter or the managing HMC (if OS is AIX or VIOS and RMC is running).
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for certain PCIe adapters and NVMe U.2 devices to lower fan speeds where additional cooling is not needed. The following feature codes are affected in the  9009-22G, 9009-41G, 9009-42G, and 5105-22E servers:  #EC5J with CCIN 59B4;  #EC5X with CCIN 59B7; and #ES1E/#ES1F with CCIN 59B8.
  • A problem was fixed for a system hang or terminate with SRC B700F105 logged during a Dynamic Platform Optimization (DPO) that is running with a partition in a failed state but that is not shut down.  If DPO attempts to relocate a dedicated processor from the failed partition, the problem may occur.  This problem can be avoided by doing a shutdown of any failed partitions before initiating DPO.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for a system crash with HMC message HSCL025D and SRC B700F103 logged on a Live Partition Mobility (LPM) inactive migration attempt that fails. The trigger for this problem is inactive migration that fails a compatibility check between the source and target systems.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for certain SR-IOV adapters not being able to create the maximum number of VLANs that are supported for a physical port. There were insufficient memory pages allocated for the physical functions for this adapter type. The SR-IOV adapters affected have the following Feature Codes and CCINs:  #EC66/#EC67 with CCIN 2CF3.
    This problem does not pertain to model ESS 5105-22E.
  • A problem was fixed for certain SR-IOV adapters that can have B400FF02 SRCs logged with LPA dumps during a vNIC remove operation.  The adapters can have issues with a deadlock in managing memory pages.  In most cases, the operations should recover and complete.  This fix updates the adapter firmware to XX.29.2003 for the following Feature Codes and CCINs: #EC2R/EC2S with CCIN 58FA; #EC2T/EC2U with CCIN 58FB; #EC3L/EC3M with CCIN 2CE; and #EC66/EC67 with CCIN 2CF3.

System firmware changes that affect all systems
  • HIPER/Pervasive: A problem was fixed for a very small timing window which may prevent the saving of volatile write cache in the NVDIMM in the event of a surprised/unscheduled power down of the system or power down with the SBE in an error state. This may result in data loss for the storage system.
    The update of the NVDIMM firmware takes approximately 8 minutes per NVDIMM. This is incurred only on the initial system boot after updating system firmware or replacing an NVDIMM. There are 4 NVDIMMs per server so up to an additional 32 minutes could be needed to complete the system boot in these cases. Please refer to section 2.5 of the readme for more information on updates to NVDIMMs. 
    This problem pertains to model ESS 5105-22E only.
  • HIPER/Pervasive: On systems with OPAL firmware, a problem was fixed for intermittent B150DAA0 and/or B181DA93 errors during power off.  On the subsequent IPL, the system will terminate with an SRC BC23352C pointing to an NVDIMM.  An NVDIMM factory reset is then required to clear that condition. Because of this error, the SBE was unable to save NVDIMM data, resulting in a loss of data.
    This problem pertains to model ESS 5105-22E only.
  • HIPER/Pervasive: On systems with OPAL firmware, a problem was fixed for a processor core checkstop with SRC BC70E540 logged with Signature Description " ex(n0p1c4) (NCUFIR[11]) NCU no response to snooped TLBIE".  This problem is intermittent and random but occurs with relatively high frequency for certain workloads.  The trigger for the failure is one core of a fused core pair going into a stopped state while the other core of the pair continues running.
    This problem pertains to model ESS 5105-22E only.
  • On systems with OPAL firmware, a problem was fixed for sporadic error messages in the OPAL log for xscom read/write calls.  These calls are handled internally and are not in the error log, so these informational messages should not be printed in the OPAL log.  
    This problem pertains to model ESS 5105-22E only.
  • On systems with OPAL firmware, a problem was fixed for a Linux OS hang on reboot that can occur if there is an error during fast reboot.  With the fix, if a fast reboot cannot be supported, a normal reboot is done instead.  
    This problem pertains to model ESS 5105-22E only.
  • A problem was fixed for a fast automatic recovery for an NVDIMM slot 0 error with SRC BC23550 logged. This is a recovery fix that changes recovery from many minutes (approximately 10 minutes per NVDIMM) with a re-IPL going through NVDIMM firmware reload, to less than 10 seconds with no re-lPL required.
    This problem pertains to model ESS 5105-22E only.
  • A problem was fixed for a missing SRC and callout for when an NVDIMM does not have enough energy is save the NVDIMM image on a loss of power for the system. Although the NVDIMM data loss is recognized by the storage system, the lack of an SRC makes it difficult to isolate the failing hardware for repair or replacement.
    This problem pertains to model ESS 5105-22E only.
  • On systems with an IBM i partition, a problem was fixed for physical I/O property data not being able to be collected for an inactive partition booted in "IOR" mode with SRC B200A101 logged. This can happen when making a system plan (sysplan) for an IBM i partition using the HMC and the IBM i partition is inactive.  The sysplan data collection for the active IBM i partitions is successful.
    This problem does not pertain to model ESS 5105-22E.
VL950_045_045 / FW950.00

11/23/20		 Impact:  New      Severity:  New

GA Level with key features included listed below
  • All features and fixes from the FW930.30, FW940.20, and FW941.03 service packs (and below) are included in this release.
New Features and Functions
  • Host firmware support for anti-rollback protection.  This feature implements firmware anti-rollback protection as described in NIST SP 800-147B "BIOS Protection Guidelines for Servers".  Firmware is signed with a "secure version".  Support added for a new menu in ASMI called "Host firmware security policy" to update this secure version level at the processor hardware.  Using this menu, the system administrator can enable the "Host firmware secure version lock-in" policy, which will cause the host firmware to update the "minimum secure version" to match the currently running firmware. Use the "Firmware Update Policy" menu in ASMI to show the current "minimum secure version" in the processor hardware along with the "Minimum code level supported" information. The secure boot verification process will block installing any firmware secure version that is less than the "minimum secure version" maintained in the processor hardware.
    Prior to enabling the "lock-in" policy, it is recommended to accept the current firmware level.
    WARNING: Once lock-in is enabled and the system is booted, the "minimum secure version" is updated and there is no way to roll it back to allow installing firmware releases with a lesser secure version.
    Note:  If upgrading from FW930.30 or FW940.20, this feature is already applied.
  • Support added for IBM Power System H922 for SAP HANA ((9223-22S) and IBM Power System H924 for SAP HANA ((9223-22S).  These models have integrated PCIe Gen4 switches.
  • OPAL is supported with skiboot level v6.6.4 and petitboot level v1.12.  This pertains to model ESS 5105-22E only.
  • This server firmware level includes the SR-IOV adapter firmware level 11.4.415.33 for the following Feature Codes and CCINs: #EN15/EN16 with CCIN 2CE3, #EN17/EN18 with CCIN 2CE4, #EN0H/EN0J with CCIN 2B93, #EN0M/EN0N with CCIN 2CC0, #EN0K/EN0L with CCIN 2CC1, #EL56/EL38 with CCIN 2B93, and #EL57/EL3C with CCIN 2CC1.
  • This server firmware includes the SR-IOV adapter firmware level 1x.25.6100 for the following Feature Codes and CCINs: #EC2R/EC2S with CCIN 58FA; #EC2T/EC2U with CCIN 58FB; #EC3L/EC3M with CCIN 2CEC; and #EC66/EC67 with CCIN 2CF3.
  • Support added for a 110V/900W power supply on the 9009-22G model.
  • Support added for IBM i 7.1 (Tech Refresh 11 + PTFs) for restricted I/O only on the S922 (9009-22A) model.
  • Support for PCIe4 x8 1.6/3.2/6.4 TB NVMe Adapters that are Peripheral Component Interconnect Express (PCIe) Generation 4 (Gen4) x8 adapters with the following feature codes and CCINs:
    #EC7A/#EC7B with CCIN 594A ; #EC7C/#EC7D with CCIN 594B; and #EC7E/#EC7F with CCIN 594C for AIX/Linux.
    #EC7J/#EC7K with CCIN 594A ; #EC7L/#EC7M with CCIN 594B; and #EC7N/#EC7P with CCIN 594C for IBM i.
  • PowerVM boot support for AIX for NVMe over Fabrics (NVMf) for 32Gb Fibre Channel.  Natively attached adapters are supported with the following feature codes and CCINs: #EN1A/#EN1B with CCIN 578F.
  • Support added for a PCIe2 2-Port USB 3.0 adapter with the following feature codes and CCIN: #EC6J/#EC6K with CCIN 590F.
  • Support added for dedicated processor partitions in IBM Power Enterprise Pools (PEP) 2.0.  Previously, systems added to PEP 2.0 needed to have all partitions as shared processor partitions.
  • Support added for SR-IOV Hybrid Network Virtualization (HNV) for Linux.   This capability allows a Linux partition to take advantage of the efficiency and performance benefits of SR-IOV logical ports and participate in mobility operations such as active and inactive Live Partition Mobility (LPM) and Simplified Remote Restart (SRR).  HNV is enabled by selecting a new Migratable option when an SR-IOV logical port is configured. The Migratable option is used to create a backup virtual device.  The backup virtual device must be a Virtual Ethernet adapter (virtual Network Interface Controller (vNIC) adapter not supported as a backup device). In addition to this firmware, HNV support in a production environment requires HMC 9.1.941.0 or later, RHEL 8., SLES 15, and VIOS 3.1.1.20 or later.
  • Enhanced  Dynamic DMA Window (DDW) for I/O adapter slots to enable the OS to use 64KB TCEs.   The OS supported is Linux RHEL 8.3 LE.
  • PowerVM support for the Platform KeyStore (PKS) for partitions.  PowerVM has added new h-call interfaces allowing the partition to interact with the Platform KeyStore that is maintained by PowerVM.  This keystore can be used by the partition to store items requiring confidentiality or integrity like encryption keys or certificates.
    Note:  The total amount of PKS for the system is limited to 1 MB across all the partitions for FW950.00.
  • Support for 64 GB 16Gbit DDR4 system memory running at 2666 Mhz with feature code #EM7B and part number 78P6815.
  • Support for 128 GB 16Gbit DDR4 system memory running at 2666 Mhz with feature code #EM7C and part number 78P6925.
System firmware changes that affect all systems
  • HIPER/Pervasive:  A problem was fixed to be able to detect a failed PFET sensing circuit in a core at runtime, and prevent a system fail with an incomplete state when a core fails to wake up.  The failed core is detected on the subsequent IPL.  With the fix. a core is called out with the PFET failure with SRC BC13090F and hardware description "CME detected malfunctioning of PFET headers." to isolate the error better with a correct callout.
  • A problem was fixed in ASMI for the Update Access Key (UAK) displaying as "0000-00-00" on the OPAL systems.  With the fix, the UAK displays as "NA" since it is not used for this type of system during the firmware update.  This problem pertains only to the 5105-22E model.
  • A problem was fixed for a VIOS, AIX, or Linux partition hang during an activation at SRC CA000040.  This will occur on a system that has been running more than 814 days when the boot of the partition is attempted if the partitions are in POWER9_base or POWER9 processor compatibility mode.
    A workaround to this problem is to re-IPL the system or to change the failing partition to POWER8 compatibility mode.
    Note:  If upgrading from FW930.30, this fix is already applied.
  • A problem was fixed for certain PCIe adapters and NVMe U.2 devices. The following feature codes are affected and the presence of these features in the 9009-41G and 9009-41A  servers can result in higher fan speeds and therefore higher acoustic levels after upgrading the firmware (the other models are also affected but to a lesser extent).  Refer to the acoustic levels published in the IBM Knowledge Center currently located at ===> https://www.ibm.com/support/knowledgecenter/9009-41A/p9had/p9had_90x.htm:
    #EC5J witn CCIN 59B4;  #EC5K with CCIN 59B5; #EC5L with CCIN 59B6; #EC5X with CCIN 59B7; #EC7A/#EC7B with CCIN  594A; #EC7C/#EC7D with CCIN 594B; #EC7E/#EC7F with CCIN 594C; #EC7J/#EC7K  with CCIN  594A; #EC7L/#EC7M  with CCIN 594B; #EC7N/#EC7P with CCIN 594C; #ES1E/#ES1F with CCIN 59B8; #ES1G/#ES1H with CCIN 59B9;  #EC5V/#EC5W with CCIN 59BA; #EC5G/#EC5B and #EC6U/#EC6V with CCIN 58FC;  #EC5W/#EC5D and #EC6W/#EC6X with CCIN 58FD; and #EC5G/#EC5B and #EC6Y/#EC6Z with CCIN 58FE.
    Note:  A version of this fix in earlier service pack FW941.03 did not add cooling for the 9009-22A and 9009-22G models for the following adapters: #EC5G/#EC5B and #EC6U/#EC6V with CCIN 58FC;  #EC5W/#EC5D and #EC6W/#EC6X with CCIN 58FD; and #EC5G/#EC5B and #EC6Y/#EC6Z with CCIN 58FE.
  • A problem was fixed for a security vulnerability for the Self Boot Engine (SBE). The SBE can be compromised from the service processor to allow injection of malicious code. An attacker that gains root access to the service processor could compromise the integrity of the host firmware and bypass the host firmware signature verification process. This compromised state can not be detected through TPM attestation.  This is Common Vulnerabilities and Exposures issue number CVE-2021-20487.
System firmware changes that affect all systems
  • On systems with an IBM i partition, a problem was fixed for the QPRCFEAT QMODEL IBM System Value showing the 9009-xxG models as 9009-xxA models.  For example, the 9009-22G reports as "EP11" instead of "EP51".  This mismatch can prevent 3rd party software licenses from working.
    The system has to be re-IPLed for the fix to take effect.  This pertains to 9009-xxG models only that are being upgraded from FW941.00.
    Note: If 3rd party software licenses were installed based on the old incorrect QPRCFEAT QMODEL value, new licenses will be needed to work with the updated value.

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: VL910_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.
