Terminology

x86 -  This term is used to reference the Intel hypervisors (KVM, VMWare, Xen) on which Virtual HMC can be installed. Note: HMC V10R2 release for x86 is not supported on bare metal (7042 hardware appliances).

ppc64 or ppc64le - describes the Linux code that is compiled to run on Power-based servers or LPARS (Logical Partitions)

General fixes

• Fixed an issue that caused the HMC to fail to fully power on and stop at the emergency shell when it was restarted following an HMC update that was performed after HMC critical console data was restored.
  
• Fixed an issue that sometimes causes PCM energy metric values to be associated with the wrong metrics on Enterprise BMC based managed systems.
  
• Fixed an issue that caused VIOS scheduled operations to be deleted when the HMC is restarted.
  
• Added the Remove action back to the GUI Shared Storage Pool Volumes page.
  
• Fixed an issue where Energy Metrics collection was not automatically enabled for Power9 and Power10 high end systems when updated to firmware levels which support Energy Metrics if Performance and Capacity Monitoring was already enabled for those systems.
  
• Closed serviceable events are no longer shown in the serviceable events slide in window on the HMC GUI dashboard.
  
• Fixed a rare timing issue that causes the Electronic Service Agent service to terminate when the HMC is booting.  When this occurs, call home and most transmit service information functions will not work.
  
• Fixed an issue that caused a delete partition operation to fail with the error "HSCL8016 An unknown error occurred while trying to perform this command.  Retry the command.  If the error persists, contact your software support representative."  This can occur on a subsequent attempt to delete a partition with vNIC adapters after the first attempt fails.
  
• Fixed an issue on the Modify Virtual Ethernet Adapter Settings GUI page for an IBMi partition that prevents a user from adding 802.1Q VLAN IDs to a trunk adapter.
  
• Fixed a timing issue that can cause an Enterprise BMC-based system to be in the No Connection state and the VMI connection to show as unavailable even though the VMI is connected to the HMC.  This can occur when multiple Enterprise BMC-based systems are concurrently being connected to the HMC after an HMC restart.
  
• Fixed a Performance and Capacity Monitoring (PCM) issue that can cause the HMC to become slow over time.
  
• Added a workaround for the issue where a keyboard configured with a non-US layout always changes to a US layout after it is disconnected and reconnected to the HMC.  The workaround to reset the keyboard layout to its original non-US configuration is to log in as user hscpe with role hmcpe and execute "runsig -s 710".  Restarting the HMC will also reset the keyboard layout to its original non-US configuration.
  
• Fixed an issue causing the hmcshutdown command to not work after HMC critical console data backed up on V10R2M1031 or later is restored on V10R2M1030.
  
• Changed call home SRC E2FF4406 to informational, there is no impact or action required from the client, this SRC is caused by a harmless issue with the HMC logging framework.
  
• Fixed a log rotation issue for the ssl_access* and ssl_request* logs in /var/log/httpd which can cause the /var file system to fill up resulting in call home SRC E212E134.
  
• Removed the System Level Deactivate operation from the list of operations for hot plug FRU operations and removed both the System Level Activate and System Level Deactivate operations from the Power On/Off Unit Advanced Functions. The proper path and flow for these actions are through the exchange fru procedures.
  
• Changed the name of the button on the Firmware Import Updates Wizard Summary page from Install to Import.
  
• Fixed another issue that prevented call home from working successfully. Symptoms include test call home displaying attempts at trying additional legacy IP addresses and fix repositories
  
• Allow users with the hmcservicerep task role to perform R&V operations.
  
• Fixed an issue that caused the following harmless messages to be logged in /var/log/messages on every HMC restart:
  kernel: alg: drbg: Failed to reset rng
  kernel: alg: drbg: Test 0 failed for drbg_nopr_hmac_sha512
  kernel: secvar-sysfs: secvar: failed to retrieve secvar operations.
  
• Fixed another issue where the browser window on the local console stayed on the "Initialization is in progress" screen after restarting the HMC.
• Fixed issue where serviceable events slide in window on the new GUI dashboard is showing more than open events
  
  

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.
