Let me guess. That storage group has data sets of widely differing sizes, causing it to become highly fragmented.the problem is probably compounded by a large number of data sets that are directed to it, perhaps of a transient nature. And I'll bet that is allowed to get far too full. Defrag is a poor solution to bad SMS design. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
