IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


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:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

vFC Mappings and Live Partition Mobility

You can do multiple vFC mappings on one physical FC port for IBM i, that is supported.

But if you want to do LPM, that is not possible.This is of course very bad, one customer got stuck with it.
We are currently rebuilding, and that is only possible because we have so many ports there, otherwise you would have to delete connections, and that is not possible at all.

Use Case:

All systems using LPM and having a virtualized environment

    IBM i supports mapping the same physical Fibre Channel port to multiple virtual Fibre Channel adapters in the same IBM i client. All LUNs (disk or tape) that are associated to that physical Fibre Channel adapter must be unique so that there are no multi-path created within the same physical port. In order to use Live Partition Mobility (LPM) or remote restart capability, you can only map the physical port twice to the same IBM i logical partition. The VIOS must be at the version 3.1.2.0, or later and the HMC must be at a version 9.2.950, or later are required for the LPM and restart the logical partition with double mapped ports support.
