This is the public portal for all IBM Z Hardware and Operating System related offerings. 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.

Resiliency in a z/OS UNIX shared file system sysplex enivronment needs to be improved related to the critical mutually exclusive serialized functions (e.g. UNMOUNT, MOVE, MOUNT RESYNC, FILE SYSTEM INITIALIZATION, FILE SYSTEM TAKEOVER, etc.). If one of these serialized functions hangs (e.g. UNMOUNT), it essentially blocks other serialized activity on all systems in the shared file system sysplex. z/OS UNIX should automtically detect when a serialized function is hung (e.g. Eventual Action Message), and if possible, perform auto-fix processing to collect debug doc and self-heal.
