General fixes

• Fix for migration vNIC Manual mappings selecting the incorrect VIOS Partitions when user specified only VIOS Partition names information.
• Automatically clean up core files present under /usr/lib64/power9/ directory that can cause SRC E35F0020 to report.
  
• Fixed the event reporting functionality to provide appropriate details of the failure of call home in generating PMH/Salesforce tickets.
  
• Fixed a UI windows sizing issue with the Install Corrective Service window that would shrink down with a long scroll bar after clicking next to progress to the "Select Service Package" panel when run on the local console session.
  
• Fixed an intermittent issue causing the selected LPAR Partition menu to not list any actions on the HMC GUI and requiring an HMC reboot to recover.
  
• Convert E2FF4600 to informational SRC.
  
• Fix an intermittent issue where the local console session boots to the "Initialization in Progress" page and does not present the login screen until a user closes the window.
  
• Fixed an issue that caused the reporting of SRC E35A0063 repeatedly during the VIOS installation.
  
• Fixed an issue that caused SRC E35A0074 and E35A0075 to report.
  
• Fixed an issue where callhome may fail on the first HMC boot up after an upgrade.  A restart of the HMC resolves the issue.
  
• Fixed an issue that causes callhome of SRC E23D040C due to core dump of the actzzmon process.
  
• Removed extraneous message "job returned error: No updates available" after performing a successful firmwre upgrade operation to a new release from the GUI.
  
• Fixed an incorrect report of heap threshold exceeded resulting in reporting of SRC E35A0043.
  
• Fixed an issue where the lslic output text would be missing from Call Home data.
  
• Changed screen saver to a blank screen for 7063-CR2 HMCs to prevent locking the KVM function in BMC.
• Fixed a rare issue that caused call home SRC E3321032 to be reported when many service events come into the HMC at the same time.
  
  

Security fix

•  Fixed an issue that allowed root access by an HMC user profile.
  

Known issues and limitations

• Kerberos server requires to be reconfigured using below CLI after update from 950 SP1 and PTFs. After update/upgrade from 950 to any newer HMC, if below scenarios via hscroot login are observed, reconfigure kerberos on HMC.
  
  
  • ls /etc/krb5.conf
    ls: cannot access '/etc/krb5.conf': No such file or directory
  • grep "kerberos.example.com" /etc/krb5.conf
    #   kdc = kerberos.example.com
    #   admin_server = kerberos.example.com
  
  Recommended CLI commands to reconfigure kerberos :
  chhmc -c kerberos -s remove –realm <kerberos_hostname> -a <kerberos_ip>
  chhmc -c kerberos -s add --realm <kerberos_hostname> -a <kerberos_ip>
