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,

CHKPPRC enhancements

1) CHKPPRC should have a 3rd completion code: Successful but with errors or warnings.

Currently there are only 2 completion codes, successful or failed. But automation tools may miss errors or warnings.

2) In a symmetrical GMIR environment, where Consistency Groups are specified as Extent Space Efficient Volumes for Preferred Source and Preferred Target, CHKPPRC should check for the existence of a current source side ESE Flash Copy. If the copy exist, post a warning on the completion.


Use Case:

1) For CHKPPRC - Automation Tools may only look for completion messages. Currently there are only 2 completion messages.
IAS0070 40 A PPRC check for the IASP CRG &1 has failed.
IAS0071 20 A PPRC check for IASP CRG &1 completed successfully

Automation software will miss Successfull CHKPPRC but with errors or warnings.

2) The existence of a stranded ESE Flash Copy could cause the Source Flash copy volumes to fill up and go write inhibited, causing an outage on the IBM I. This is an additional safety check to ensure no ESE Flash Copy relationships remain inadvertently.

    Thank you for submitting your request. However, this is not a request for the IBM i or PowerHA products. Rather, CHKPRC is part of an IBM Lab Services tool. Therefore, your request is being Declined. Normally, we would ask that you contact IBM Lab Services to pursue enhancements to their tools, however, in this case, we were informed that they had already handled this particular request.
