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.

Write correct device name in SAVLIB output file when using media definition with multiple devices

We use SAVLIB *ALLUSR DEV(*MEDDFN) MEDDFN(xxx) OUTPUT(*OUTFILE) in our weekly backup, where the media definition xxx contains two devices with 3 tapes each and specify a save format of *SERIAL, i.e. each library is saved to only one device.

This works fine - no problem here.

But the output file from the SAVLIB operation contains an incorrect value in the column SRODEV (save/restore devices)! All rows in the output file has the same value, which is the first device specified in the media definition - even though the library and object is saved to a tape in the second device.

The volume name in column SROVOL in the output file is correct - even when spanning multiple volumes - but the device value is wrong...

The problem has been verified on both IBM i 7.3 and 7.4.


Use Case:

If corrected, the value of SRODEV would show which device were used for writing the lib/object to tape in a parallel backup - currently it can not be trusted.

    IBM will use this request as input to planning but no commitment is made or implied. This request will be updated in the future if IBM implements it. IBM will use votes and comments from others in the community to help prioritize this request.

    The CEAC has reviewed this requirement and recommends that IBM view this as a MEDIUM priority requirement that should be addressed.

    Background: The COMMON Europe Advisory Council (CEAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.

    To find out how CEAC help to shape the future of IBM i, see CEAC @ ibm.biz/BdYSYj and the article "The Five Hottest IBM i RFEs Of The Quarter" at ibm.biz/BdYSZT

    I've added my vote to this based on IBM's solution, it sounds like a good way forward to me.

    IBM needs more information to further assess your Request for Enhancement.

    IBM i Development reviewed this request and found the SRODEV field can contain up to 4 devices which is less than the maximum number of devices which can be used in a parallel save or restore operation. Development doesn't see any benefit in having a partial device list in the field (which is basically the behavior now). A comprehensive solution is to create a new expanded device field to support the maximum amount of devices possible. An outfile change has release boundary restrictions, and there are several higher priority needs ahead of this request, so it would likely be at least a few years before this proposed comprehensive solution could be delivered.

    IBM would like to know if this request is still desirable given this timeframe?
