This document helps you to identify, describe, report, and resolve DFSMSdfp failures. It also you gather detailed DFSMSdfp failure-related data. You typically gather this data after identifying a failure and determining that an APAR record does not exist for it in the IBM software support database. It is not intended to enable you to do in-depth problem diagnosis. When the diagnosis procedures in this book or the IBM® Support Center directs you to this document, you should use the reference information in this book to gather and interpret failure-related data that supplements any data obtained from the initial failure.
