This portal is to open public enhancement requests against IBM System Storage products. 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).
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:
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 an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

Due to processing by IBM, this request was reassigned to have the following updated attributes:

For recording keeping, the previous attributes were:
Brand - Tivoli
Product family - Storage

Thank you for submitting this request. While we understand the use case and the desirability of a solution, the MAXSIZE parameter is really intended for non-sequential data. The best practice is that the storage pools should have the same attributes all the way through especially when using simultaneous write. At this time there are no plans to implement a solution for the described use cases as this is not in good alignment with strategic directions. If after the next release of the product you would like to have this enhancement request reconsidered, please resubmit your request.
