Terminology

x86 -  This term is used to reference the legacy HMC that runs on x86/Intel/AMD  hardware for both the 7042 Machine Type appliances and the Virtual HMC that can run on the Intel hypervisors (KVM, VMWare, Xen).

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

DNS - Domain Name Server

GUI - Graphical user interface

vHMC - Virtual HMC. The HMC appliance that runs in supported VM Hypervisors

• Support for updating ASMI admin password using chsyspwd command without specifying the current password on supported FW levels. 

List of fixes

General fixes

• Fix to prevent a deadlock in HMCSession.destroy resulting in call home SRCs E35A0034 and E35A0035 and data replication function delay
  
• Added new state information to the lscodpool --level pool command, the PowerEnterprisePool REST object, and to the Power Enterprise Pool GUI to indicate when the pool is in a needs update state due to a pool update or recover operation that failed to successfully enter the pool processor resource entitlement code or the pool memory resource entitlement code.
  
• Updated logic to display the proper hostname in the lsprimhmc command.
  
• POWER9 or POWER9_ADVANCED Processor compatibility modes are now supported in Templates.
  
• Fixed an issue where adding an HMC during the Create Power Enterprise Pool task failed when the HMC hostname was specified and the hostname was for an HMC Ethernet interface other than eth0.
  
• The predefined HMC task role hmcclientliveupdate, which is used for AIX Live Kernel Update (LKU) operations, has been updated to support Power Enterprise Pool related operations.
  
• Fix to display AIX, Linux, and VIOS partitions that have names containing "os400" in the vtmenu output
  
• Fixed PCM utilization data for SR-IOV adapters operating in dedicated mode that caused the following error to be displayed:
  "Error Code 3004 failed to fetch SRIOV adapter physical port statistics due to a technical error."
  
• Added checks to validate syntax and return an error when mkauthkeys is run without the SSH key as the last argument
  
•  Fixed an issue when the prefix length is provided for an IPV6 address while activating an lpar using the GUI resulting in error "The IPv6 address is not valid. Please specify IPv6 Address in <ip_address>/<prefix_length> format."
  
• Fix to display the promiscuous mode setting for logical ports in the Add VIOS wizard.
  
• Fixed an issue when sending gzipped files (FSPDUMP, SYSDUMP) weren't getting transferred with the .gz extension on transmission to IBM.
  
• Add new field of RAID rebuild status to the lshmc -h command
  
• Enabled auto population of the partition ID in templates to prevent the message "Error in Create Partition. Unable to retrieve an equivalent CHILD object after the requested operation."
  
• Fix for a DHCP lease file parsing issue which was causing the HMC to not auto-discover one or more systems which were DHCP clients.
  
• Fix to prevent garbage characters from displaying for Japanese locale in the status and title bar during Launch Guided Setup Wizard locally at the HMC console.
  
• Fixed an issue that would cause some offload to media operations to fail to copy service event files to USB media even though the offload returned success.
  
• Heuristic changes to panels for improved useability.
  
• Improved performance of closing serviceable events in Serviceable Events Manager.
  
• Fixed VSCSI Storage Attachment during Partition Template Deploy Operation to prevent the deployment from failing with the given disk name xxxx already exists.
  
• Fix to prevent the RPM command from hanging while collecting a HMC Critical Console Backup.
  
• Improved logic for how event duplicates are determined when being reported in the same incident pool timeframe.
• Fix for 'Backup Management Console data' which shows running on task panel indefinitely even after rebooting the console.
  
  

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.
