Terminology

x86 - This term is used to reference the Intel hypervisors (KVM, VMWare, Xen) on which Virtual HMC can be installed. Note: HMC V11 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). Note: HMC V11 release for ppc64le is not supported on 7063-CR1 hardware appliance.

General fix

Fixed an issue that can cause a blank screen to appear when the GUI performance dashboard or environmental dashboard is launched. This issue occurs when only dedicated processor partitions exist and there are no available processors on the managed system.

Known Issues and Limitations

Dates, times, and numbers on the GUI Performance dashboard are shown in the format based on the HMC language instead of the browser language.
Occasionally a Kerberos user login may fail even when the credentials are valid. As a workaround, try logging in again with the same credentials after a short delay of 15 to 30 seconds.
Using the search function on the Partitions table on the new GUI takes several seconds to update the table when the HMC is managing many partitions.
The Update system, VIOS, adapter levels task shows in the Task log with a status of Completed but the progress bar on the task’s GUI page may still show it is applying updates. Refer to this document https://www.ibm.com/support/pages/node/7240073 for more information.
Several dconf related warning messages are displayed when running the asmmenu command. Those messages can be ignored.
For the optimal video resolution configuration for HMCs connected to the "IBM Rack-Mounted Flat-Panel Console Kit with Keyboard (ETF6)" see the article - https://www.ibm.com/support/pages/node/7239295
Create Serviceable Event fails with REST0192 Invalid argument class when entering a description that is not a simple one line sentence (i.e. if it contains a CR/LF, the action will fail). Refer to this document https://www.ibm.com/support/pages/node/7243098 for more information/remediation.

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.

Call home - It is recommended to enable call home on the HMC to allow error reporting for faster problem resolution, inventory collection, and sending other periodic data. For more information review the IBM Call Home brochure and how to enable Call Home on V10.

MF71732/MF71733
08/21/25

Fixed an issue where saving new settings on the HMC settings GUI page causes network bond interfaces to be deleted.
Extended the amount of time the Test Call Home function will wait for the ticket to be received before returning the following failure sequence even though the ticket was successfully created and returned
Symptoms included:
- REST0370 Creating test problem
- REST0371 Test problem created:xxx
- REST0372 Submitting problem for callhome
- REST0374 Test failed
- REST0358 No PMH is received, please check console log for more details.
Fixed an issue that prevented an HMC user with a custom resource role from being able to launch the Create partition or Create VIOS task on the GUI for a Power11 system.
Fixed an issue that prevents a user from collecting the HMC diagnostics file (pedbg) when selecting a system and then Service > Create serviceable event.
Changed the time zone used on the Power mode GUI page when setting a schedule for power mode changes for a managed system to match the HMC time zone.
Fixed an issue that caused the speed 1000Mbps Full Duplex to be missing from the list of Media speeds on the HMC management > Network settings > Edit LAN adapter page. If the media speed for the LAN adapter was already set to 1000Mbps Full Duplex, previously it was incorrectly shown as 1000Mbps Half Duplex on that page.
Fixed an issue that prevented the hscpe user from collecting the HMC diagnostics file (pedbg) when creating a serviceable event via the HMC GUI.
Fixed an issue that causes the PCM dashboard to show no data when the HMC timezone is set to "GMT+<x>" or "GMT-<x>".
Fixed glib2 vulnerabilities: CVE-2024-52533, CVE-2025-4373
Fixed sudo vulnerability: CVE-2025-32462
