HMC V9 R1 introduced support for managing POWER9 systems and V9 R1 M930 is the next update for Release 1. In this blog, let’s take a quick look at the enhancements in HMC V9 R9.1.930.

To get things started, V9 R1 M930 is a service pack for the V9 R1 release which means, you would update (Not Upgrade or fresh install) to 930 from V9 R1 M910 with or without additional Service Packs or PTF’s. Please note that you would have to update to M930 to get service fixes for V9 R1 going forward.

PowerVM:

  • Live Partition Mobility (LPM):
    • Allow a managed system to concurrently be both the source and target of multiple migration operations
      • Allow two migration operations, one from server A to server B, and one from server B to server A, to be launched concurrently, and complete without error.
      • Allow three migration operations, one from server A to server B, one from server B to server C, and one from server C to server A, to be launched concurrently, and complete without error.
    • HMC V9 R1 M930 aligns with the FW930 firmware, which brings secure accelerated LPM to all POWER9 servers, including scale-out models
  • Support to show available managed system’s stealable processor and memory values
  • Support to show remaining non-IFL processors for hosting AIX or IBM i partitions

Enhanced UI Improvements:

  • Enhanced Quick Create Partition to support multiple partition creation
  • Simplified adding virtual networks to load group by providing an option to directly add a network to a load group instead of going through Add Network Wizard
  • Added filter option to Physical Volume, Physical IO table views and other tables where there are a large number of entries.
  • Provided option for a user to choose Physical IO when deploying using templates, in case a match is not found on the system with the captured IO info (both system & partition templates)

  • Added Deferred/Activated firmware level as a selectable column in the dashboard view for systems
  • Added memory mode as a selectable column in the dashboard view of partition

  • Provided install option as part of partition template deploy and added a separate install menu option at partition level

  • Disabled “Bridge Internal Network” option for virtual networks corresponding to PVID of a load group

Performance Improvements:

  • Improved the launch time for Virtual NIC panel at partition level

HMC Management & Security Enhancements:

As a follow up support for managing IBM POWER9 AC/LC systems, the following enhancements have been added in V9 R1 M930

  • Establishing concept of primary management console to prevent duplication and provide redundancy
  • Enhancement to collect and display system metrics: power usage, temps and to show LED status.
