Pre-allocated dump data sets are direct access data sets with names of the form SYS1.DUMPxx, where xx can be any decimal number from 00-99. You can allocate SYS1.DUMPxx data sets with both primary and secondary extents. When you allocate a dump data set, specify enough secondary extents to hold the entire dump. Also, specify RECFM=FB, LRECL=4160 and BLKSIZE=4160.
When automatic allocation is active, the dump is written to SMS-managed storage or to DASD volumes. The system allocates dump data sets of the correct size at the time a dump is requested. No pre-allocation is required for them.
