Power11 System Firmware Fix History - Release levels OF11xx

Impact: Availability     Severity: SPE

A problem was fixed for concurrent firmware activation updates from FW1110.02/FW1110.03 to FW1110.10 and future Service Packs. 

Systems which have booted on FW1110.10 will operate normally. The resolution to this issue is that activating the FW1110.11 Service Pack will be a disruptive activation. 

The FW1110.11 Service Pack has the same functional content as FW1110.10. You may choose to move to FW1110.11 or a future FW1110 Service Pack during a disruptive service window, so future FW1110 Service Packs may be concurrently applied.

Firmware version FW1110.10 contains a defect that can cause concurrent
firmware updates from this release to fail for eBMC based systems.

Status:

FW1110.10 for Fix Central has been archived.

A new firmware release (FW1110.11) will address this issue and planned
availability in early January. This system firmware level will be
disruptive to apply.

Impact:

eBMC systems that booted with FW1110.10 will operate normally.

Action Required:

No immediate action is required.

• Support was added for PCIe x16 dual monitor graphics adapter (FC EC90).
• Support was enhanced for Link Layer Discovery Protocol (LLDP) capability when an adapter is in SR-IOV shared mode, allowing collection of network topology information via network switches.
• Support was added for Link Layer Discovery Protocol (LLDP) on IBM Power System E1180 (9080-HEU).
• Support was added for “inband” HMC to OS communication (RMC Connection). This eliminates external network dependencies for RMC for OS versions that are enabled for in-band RMC.
• Support was added for The Linux Integrity Measurement Architecture (IMA). IMA verifies signatures against critical BMC software components, measuring and logging these measurements in the TPM and allowing attestation of these results at runtime.
• Support was added to auto provision vTPM during partition creation, provisioning a signed endorsement key certificate during instantiation to provide that proof of authenticity.

• A change was made to suppress logging TPM failures with SRC B7009009 during TPM health checks.
• A problem has been fixed where a combination of communication fails to the power IC devices on a DDIMM could result in an IPL crash, with no log indicating which parts caused the fail. This fix will properly call out and deconfigure the failing DDIMM.
• A problem has been fixed to improve the firmware selection of processor cores added to an active dedicated processor partition.
• A problem was fixed for a multi-port adapter failing to configure or encountering performance impacts. The problem only pertains to multi-port adapters in an ENZ0 PCIe4 expansion drawer. The problem does not pertain to adapters running in SR-IOV shared mode. After installing the firmware service pack containing this fix, the partition(s) owning the impacted adapter(s) will need to be rebooted or the adapter(s) will need to be dynamically removed and added back to the partition(s) for the fix to activate for the impacted adapter(s).
• A problem was fixed for a possible system termination with SRC B700F105 after changing the I/O configuration or deleting a partition that is in the failed state with the SRC B2001230.
• A problem was fixed for a possible system termination with SRC B700F105 when running KVM in a PowerVM LPAR.
• A problem was fixed for a system state of incomplete on the management console which is not recoverable with a "Recover system" option of the managed system. The problem occurs when a new partition is created on the system, but the internal representation of the partition is not completed. The fix allows for the system firmware to validate partition creation is complete and will synchronize inconsistencies in the partition representation.
• A problem was fixed for network adapters with Feature Codes EC24/EC26 where traffic loss for SR-IOV logical ports configured on the adapter may occur and SRC B400FF02 platform event log will be created. This problem may intermittently occur when the adapter is configured in shared mode and a manually initiated resource dump is initiated from the HMC or ASMI targeting the adapter.
• A problem was fixed in firmware that prevented the external stand-alone USB DVD (Feature EUA5) from being selected as a boot device via the SMS menu and the SMS macros.
• A problem was fixed in the Power Hypervisor code where resources assigned to Virtual Functions may be deallocated even when there are configured VF resources for partitions. This could happen during hardware repair or replacement (FRU Repair or Exchange) if the VF resources weren’t removed from the operating system before starting the procedure.
• A problem was fixed where a concurrent firmware update would fail and the system would go to Incomplete state on the HMC.
• A problem was fixed that prevented the HMC from displaying daily notifications on the GUI and sending daily email notifications for a system in a Power Enterprise Pool 2.0 (PEP 2.0) whose PEP 2.0 Capacity on Demand code was within 7 days of expiration.
• A problem was fixed to continue to configure all the PCIe Switch slots under a PCIe Switch when one of the slot initialization operations fails under the PCIe Switch. The problem occurs only when there is an issue with one or more slots in IPL under PCIe Switch. This fix is applicable for all PCIe Switches in System Units and in IO Expansion Units.
• A problem was fixed where a B2006002 SRC may be seen when re-IPLing a system with 2 or more SR-IOV adapters in shared mode, even though no adapters were replaced. The failed SR-IOV adapter can be powered on again and it should boot correctly.
• A problem was fixed where a serviceable event for a processor issue was logged with an incorrect call out.
• A problem was fixed where AIX Update Access Key (UAK) expiration HMC notifications are logged along with A7004763 and A7004764 SRCs on IBMi partitions on systems with no AIX LP installed. With the fix, these notices will be suppressed if no AIX partition exists on the system.
• A problem was fixed where booting to the SMS menu and executing a specific SMS key sequence could cause undefined behavior. The problem may occur if a user executes the following key sequence upon boot to the SMS menu: 5 (Select Boot Options) ->1 (Select/Install boot device) ->5 (List all Devices).
• A problem was fixed where firmware might get out of sync after a runtime code update followed by a memory-preserving IPL. The fix addresses the issue and ensures proper security checks pass with the new code.
• A problem was fixed where if all TPM (trusted platform module) hardware has been marked as failed in the hypervisor, the hypervisor will block live partition migrations with the system key and capacity on demand activation codes from being applied.
• A problem was fixed where long running CoD based firmware operations, such as the processing of applied entitlements, may time-out. This results in the server state being set to incomplete on the HMC, which will require a rebuild of the server.
• A problem was fixed where Power Enterprise Pool 2.0 (PEP 2.0) and virtual serial number activation codes applied on the HMC may time-out.
• A problem was fixed where the hypervisor could allow memory to be over-configured on the system, leading to inconsistent memory values and errors on the management console.
• A problem was fixed where the hypervisor was reserving too much memory for SR-IOV adapters that are configured in shared mode. Activating this service pack will automatically resolve the issue and free up memory on the system.
• A problem was fixed where the SMS boot position (index) may not populate properly. SMS options: 5 (Select Boot Options) -> 1 (Select/Install boot device) ->5 (List all Devices). Workaround: SMS options: 5 (Select Boot Options) -> 2 (Configure Boot Device Order) -> [ESC] -> 5 (Select Boot Options) -> 1 (Select/Install boot device) -> 5 (List all Devices).
• A problem was fixed where unnecessary SBE Updates were being performed on Cold IPLs (ie, the system is powered off before IPLing/booting). The solution better determines if a SBE Update is really necessary on a Cold IPL and saves IPL time by bypassing any unnecessary SBE Updates.
• A problem was fixed where preventative errors were being flagged incorrectly and unnecessarily during testing. This fix reconfigures the flags that are set for watching for these preventative errors.
• Add a recovery mechanism to work around hardware erratum on certain PMIC components on certain 4U DDIMMs which would otherwise cause them to reset voltage settings leading the DIMM to run in N-mode until the system reboots.

• A problem was fixed in firmware that prevented the external stand-alone USB DVD (Feature EUA5) from being selected as a boot device via the SMS menu and the SMS macros.
