General fixes

• Added a reason for the Version Mismatch system state to the State detail field.
  
• Added missing information to the About HMC V10 GUI page so that the same information available in the old dashboard is now available in the new dashboard on the About page.
  
• Changed a partition migration warning message for the case when one of the source VIOS’s hosting one of the partition's virtual Fibre Channel (FC) adapters supports FC port labels but the destination VIOS does not.  The previous message was misleading "HSCLC3C8 There was a Fibre Channel (FC) port label mismatch for the partition's virtual FC client adapter " to now the correct message of "VIOS does not support FC port labels".
  
• Fixed an issue so that any TLS 1.3 ciphers removed from the HMC Web user interface via the chhmcencr command prior to an HMC update or upgrade remain removed after the update or upgrade.
  
• Corrected the Allocated processors value shown on the GUI in the VIOS table for Virtual I/O servers configured with a processor mode of shared uncapped.
  
• Disabled editing of the Jumbo Frame checkbox on the Modify Virtual Network Bridge GUI page since the jumbo frame setting cannot be changed dynamically.
  
• Fixed a rare timing issue that can cause SRC E3550046 to be reported if a CoD console message is being displayed on the GUI at the same time a user logs into the GUI.
  
• Fixed an issue causing an attempt to activate deferred firmware updates on an Enterprise BMC based managed system to always fail with the following error message:  Error. Cannot invoke "com.ibm.sfp.updates.openbmc.UpdaterEBmc.getUpdateImage()" because "updater" is null.
  
• Fixed an issue causing Firefox on the local HMC console to make background connection calls to Amazon and Google Cloud.
  
• Fixed an issue causing HMC ethernet interfaces configured as DHCP clients to go down after updating the HMC network settings.
  
• Fixed an issue causing SRC E35F0010 to be reported multiple times after upgrading the HMC to V10R1M1010.  This problem occurs on HMCs with custom scheduling for Serviceability -> Service Management -> Transmit Service Information for Disk Health that was created when the HMCs were at a level earlier than V10R1M1010.
  
• Fixed an issue causing the following harmless events to be logged every 3-10 minutes in /var/log/messages:
      systemd[1]: dev-disk-by\x2dlabel-EFI.device: Job dev-disk-by\x2dlabel-EFI.device/start timed out.
      systemd[1]: Timed out waiting for device dev-disk-by\x2dlabel-EFI.device.
      systemd[1]: Dependency failed for /boot/efi.
      systemd[1]: boot-efi.mount: Job boot-efi.mount/start failed with result 'dependency'.
      systemd[1]: dev-disk-by\x2dlabel-EFI.device: Job dev-disk-by\x2dlabel-EFI.device/start failed with result 'timeout'.
  
• Fixed an issue causing the system firmware level of an Enterprise BMC based managed system to be missing in the system inventory VPD.xml file.
  
• Fixed an issue preventing SRC B303000E from being reported for an Enterprise BMC based managed system and the system from transitioning into No Connection state when the Enterprise BMC becomes unreachable on the network.
  
• Fixed an issue that caused "-" to be shown for all the usage values on the Usage page of the Partitions table in the new GUI dashboard.
  
• Fixed an issue that caused PCM aggregated metrics to no longer be generated after the HMC time was moved forward or when Daylight Saving Time starts.
  
• Fixed an issue that caused SRC E320F817 to be reported and called home after a successful firmware update on a single-FSP system.
  
• Fixed an issue that caused SRC E35A0033 to be generated and called home repeatedly.  This issue only occurs on 7063-CR1 HMCs that have a large number of BMC events.
  
• Fixed an issue that caused the Autoconfigure IP Addresses setting for IPv6 be shown incorrectly for an HMC Ethernet interface after a clean install of the HMC was performed when there was no cable connected to that ethernet interface.
  
• Fixed an issue that caused the event notification email notification setting of "All scheduled operations" to be lost after an HMC update or upgrade, causing notification emails for scheduled operations to stop.  This issue only occurs when the HMC version prior to the update or upgrade is V10R1M101x and the version after the update or upgrade is V10R1M1020 or greater.
  
• Fixed an issue that caused the lslic -t sriov command to fail with the error:   "HSCF0004E An error occurred trying to survey the target mmmm-ttt*sssssss. Please verify the connection to the managed system." even though the managed system was connected and in Operating state.  This error can occur when there is a stale connection to the managed system, or  the redundant service processor in the managed system is in No Connection state.
  
• Fixed an issue that caused the updlic command to fail when the "-l latest" option was specified when upgrading the firmware on an Enterprise BMC-based managed system to a new release.
  
• Fixed an issue that causes a successful system firmware update operation that takes more than 3 hours to complete to return the following error on the GUI: "COMPLETED_WITH_ERROR: java.lang.interruptedException: Timed out waiting for the process to exit."
  
• Fixed an issue that causes in-band BMC communication on a Power HMC to fail after restoring HMC upgrade data that was migrated with network configuration data from a CR9 HMC.
  
• Fixed an issue  running the scheduled operation for hardware VPD  from a system with a large number of partitions collecting inventory that caused SRC E212E136 to be generated and called home.
  
• Fixed an issue where changing server settings on a new server that is powered off may disable memory mirroring.
  
• Fixed an issue that caused the following warning message to be displayed when updating the HMC:  "Installing Packages...warning: /dump/hsc_install.images/images/install.d/java/ibm-java-sdk-17.0.5.0-x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 9bce9629: NOKEY"
  
• In the update system firmware wizard, when the highest level in the selected system firmware repository is already installed, the default "Target Level" was changed to "Do Not Update".
  
• Re-enabled the "Use virtual OptiConnect" setting in the Edit Profile GUI.
  
• Updated the rrstartlpar man page and error message to clearly indicate that the --usecurrdata command option must be used to restart the partition when its remote restart data is stale.
  
• Fixed an issue that causes one of two HMCs trying to connect to an Enterprise BMC-based managed system to fail to connect to the VMI due to choosing the wrong VMI IP address to connect.  This issue occurs when the HMCs are configured with DHCP on separate private networks.
• Fixed an issue that may cause /var to fill and SRC E212E134 to be reported due to excessive taskcontroller ssl log entries.
• Fixed an issue that resulted in call home SRC E302F817 at the successful completion of a code update.

• Fixed an issue that caused SRC E35F0013 to erroneously be generated and called home sometimes immediately after updating or a subsequent reboot later.

Best Practices

• User sessions - The following best practices helps avoid performance degradations gradually over a period of time due to increased login sessions as well as security vulnerabilities such as unauthorized access to the active HMC sessions.
• It is a best practice to logoff from HMC UI and then close the browser tab instead of directly closing the tab
• Set Idle session timeout for all the users and not leave the timeout as '0' which leaves it as no timeout.
• Profile recommendations - The maximum number of partition profiles suggested per partition is 10.
