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.

provide command to reset (IPL) CMBxx adapter

Please provide command to reset hardware adapter from command line rather than need to sign on to SST, go to hardware service manager, search for correct adapter and IPL I/O processor.

Use Case:

As we see more and more LPARs being virtualized (NPIV) we have the need more often to IPL IOPs to rescan FC network for new, changed or removed devices.
Mostly we see this for tape handling issues. As a lot of tape drives are capable of being attached through multipath we not only have to reset one but at least two CMBxx adapters.
Depending on setup - if you have a second tape library on a second location - we might have to reset 2 more adapters.
And this for multiple LPARs!

    The request does not match any similar commands that the QSMGSSTD API provides. The potential command could cause unwanted system behavior because it wouldn't be able to determine if it is safe to perform the IPL of the IOP bus adapter

    It is recommended that tape devices are not mixed with DASD devices on an adapter. The recommended and correct way to IPL the IOP, if there is no DASD devices attached to the IOP, is to vary off all the devices attached to the IOP and then vary on one of them on with reset. There are already APIs and commands that a user can use to write a tool that could automate the varying off of all the tape devices and vary on one of the tape devices, for each IOP, with RESET(*YES).

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.
