The IBM Support Portal
is a unified, centralized view of all technical support tools and information for all IBM systems, software, and services. You can tailor the portal pages to suit your requirements, focusing on the products you care about and organizing the pages to reflect the way you work. The goal is to simplify the online support experience, reduce the time it takes for you to solve problems, and alert you to information that helps you avoid problems.
