Multiple-extent load libraries have been discouraged since the days of OS/360; and, since real, spinning DASD is now a rarity of interest chiefly to archeologists, there is no longer any excuse for them for them.
In the old days IBM's [DASD] storage estimates were often low, so that secondary extents were created during SYSGENs; but such problems are long behind us. Make your libraries single-extent before your next IPL, and consider making those that can be PDSEs instead of PDSs. The storage required to do so can be calculated in an obvious way from the multiple-extent storage they now occupy with some provision for growth.
