IBM Power Ideas Portal

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Start by posting ideas and requests to this portal to enhance a Power product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas and add comments to ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The Power teams will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

power supplies status check

We need a way to determine power supplies status for IBM Power Systems Server deployed with PowerVM and HMC in a remote data-centre.

Just like HP iLO or old IBM's IMM (Integrated Managemnt Module for x86 server) displays a red or green icon per power supply.

This is a basic RAS requirement.

This functionality could be provided in ASMI or even be displayed in the HMC.

(also see Case TS001784409 )

    I've determined that the legacy (Pegasus) CIMOM works with the ASMI to report CEC and Power Supply usage (apparently in watts). No up/down status is available but a down PS should read as 0 watts. I'm updating this RFE for any other viewers.

    An example and output is documented in the IBM EnergyScale for POWE9 Processor-Based Systems doc on page 22 & 23. Pdf copy here:

    Collection is done via wbemcli
    Nigel G. did a video on this client:

    I used a wbemcli rpm for Centos on RHEL7 ppc64le. Found here:, sblim-wbemcli-1.6.2-11.el7.ppc64le.rpm
    There are newer versions at rpmfind but they appear to requires RHEL8. There are also supposed to be Windows versions but I did not look for them.

    Your fsp/asmi must be accessible from an lpar/client as you can't put his on an HMC.

    I can't speak to the support for CIMOM on Power, but given xCAT also uses this provider for Power (in fact, it does support this same collection) it may be still well used by HPC staff and IBM SSRs and hard to deprecate. I'm not an xCAT user so unable to verify but you can google on those power metrics and xCAT and the code is current.

    Also will note that when HMC 8.6 came out with Performance Capacity Monitor metrics and REST API, the IBM docs say that Aggregated metrics would include power/energy information at a later date. There does not appear to be any way to turn this on from the HMC and I've checked new PCM collections and there are no power metrics. I suspect the REST API works but you would have to write that and turn it on. Details here:

    I think I found the pcm properties file location on the HMC and I presume power/energy enablement switch in there but the file is not viewable/editable (ccfw user and I can't change that).
