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
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

IBM agrees with the request and a solution appears to be desirable and feasible. IBM intends to provide a solution. However, IBM's plans may change and no commitment is made that a solution will be provided.
IBM's plan is to include the size of data processed in the status message, but will not include a percentage of the total. It is not feasible to save the total number and size of the objects prior to saving the object data.
The CAAC has reviewed this requirement and recommends that IBM view this as a high priority requirement that is important to be addressed. The information needs to be saved at Save time, similar to how a save of *NONSYS or *IBM is stored in the QFILE on the tape. This is really important to plan for proper restore timings.
Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key 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.

Submitter and/or Voters: Please respond to the question in the Comment from IBM below, namely: "Would it satisfy the request if RST adds the amount of data (GB) that has been restored to the existing RST status message? RST cannot provide % processed/remaining because the total number of objects and amount of data is not known until the RST is complete."
This would be extremely useful in migrations and restores, and is a high priority.
The COMMON Europe Advisory Council (CEAC) has reviewed this requirement and recommends that IBM view this as a “nice to have” low priority feature.

IBM needs more information to further assess your Request for Enhancement.
Would it satisfy the request if RST adds the amount of data (GB) that has been restored to the existing RST status message?
RST cannot provide % processed/remaining because the total number of objects and amount of data is not known until the RST is complete.
IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.
RST cannot provide % processed/remaining because this is not known. RST might be able to provide status for size of data processed in addition to number of objects processed.
In both cited cases (native and IFS restore) the system just tells you where it is currently at and leaves it up to you to be familiar enough with your data to know how many remaining objects (and their size) are yet to be done and be able to figure out how long that would take. Because folks are usually less familiar with their IFS objects and sizes than their native libraries the tracking information currently provided by the restore is less useful for IFS restores. The requested functionality, if added, should be added to both the IFS and native environments. If a % complete is to be provided, would that be based on total bytes or # of objects ? If # of objects, then that information is available to the restore program from the save media. Then it becomes a question of what information is available in the media header. If the number and size of the objects are not there it would require the restore to completely read the save media prior to the restore to collect this information. In the case of tape media, this would significantly extend the time of the restore. If # of bytes, I am not sure that that information is even contained on the save media at all so that might not even be an option. Even if it is, it would entail the same overhead that the number of objects would. Unless the information needed is available within the media header I think the execution cost of this information is not worth what would be gained by it.
