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.

Retype (migrate) volume between mirrored storage templates (different pools, same storage provider)

Problem:

If you have a mirrored volume in PowerVC (Storage-Template-A) and you have to retype (migrate) this to also mirroed Storage-Template-B for any reason, this didn't work/isn't supported.

Most customers, which do have a SVC, are using mirroring between pools to have high availibility. Therefore they also use the often the streched cluster feature of SVC. So they do have 50% of SVC in datacenter room 1 and the the other 50% in datacenter room 2. In each room they do have also a storage box "behind" the SVC, lets say pool-1 and pool-2. And PowerVC do support such a scenario. But if the pools are full, or the storage boxes have to be replaced, how should hundreds of volumes being moved form pool1/pool2 to the new pool3/pool4 ?

The log way is to migrate the volume outside from PowerVC (with SVC commnds), and then fix the information in PowerVC for the volume ...
# powervc-config storage set-template ...


Not the best solution, if you have a management tool like PowerVC ...

Plese provide this feature in PowerVC with the retype function.

And don't forget to update the REST API ;-)
