Terminology

x86 -  This term is used to reference the Intel hypervisors (KVM, VMWare, Xen) on which Virtual HMC can be installed. Note: HMC V10R3 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 a timing issue that can cause a 500 error to be returned to a Get ManagementConsole REST API call when another HMC session is logged out just after the Get call is made.  The 500 error returned has a reason code of "Unknown internal error." and a message of "Cannot invoke "com.ibm.hwmca.fw.servlet.util.HMCSession.getUserContext()" because "session" is null".
  
• Fixed an issue when performing a partition migration validation operation on the GUI that caused edited vNIC or SR-IOV mappings to disappear from the GUI when submitted for validation again.
  
• Fixed an issue that caused the name of a shared processor pool on an Enterprise BMC-based managed system to be reset to the default name after the maximum or reserved processing units for the pool was changed.
  
• Fixed a rare issue that can cause a managed system to go into Recovery state and also prevent the managed system from being recovered with rstprofdata or mkprofdata.
  
• Fixed an issue that caused the PCM REST API get of processed or aggregated metrics to fail with the 500 error "An I/O error occurred sending to backend" and caused the PCM GUI to fail to load any data.
  
• Fixed an issue causing the sed command to fail when a command argument contains a dash.
  
• Fixed an issue that can cause Transmit Service Information operations to fail after upgrading the HMC to a new release.
  
• Fixed an intermittent issue that causes SRC E3550037 to be called home when the reference code history of a partition is displayed on the GUI.
  
• Fixed an issue causing an SMTP server to fail to receive email notifications when the IP address specified for the SMTP server has a trailing space.
  
• Fixed an issue that caused the following error to occur when using the GUI to upgrade the HMC: "An error occurred while downloading the upgrade file.Files not obtained from server. Check to see if the hostname, user id, password and directory entered are valid."  This error occurs when no directory is specified for the download location.
  
• Fixed a timing issue that causes nothing to happen and no error to be displayed when the USB option is selected on the Update VIOS GUI page.
  
• Secure SMTP has been enhanced to use all available transport protocols of HMC instead of only TLS 1.3.
  
• Fixed an issue where the Last Reported Time on the GUI Manage Serviceable Events page displays the current time instead of the last reported time. This issue only occurs when the language is Korean.
  
• Fixed the description shown on the Serviceable Events page for SRC B158BA2A.
  
  

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.
