Based on the record statement and the FILSZ specified, DFSORT estimated it would need 469577MB of disk work space. Your installation default for DYNALOC is probably the shipped default of SYSDA,4. This is going to cause DFSORT to allocate 4 work data sets. The work space allocation will be spread across three of those with one set aside to be used for recovery if the work space requirement is larger than expected. So with such a small number of work data sets, you need to have at least 3 volumes with 156526MB of free space. Since there were not any volumes available with that much free space, your sort failed. On your OPTION statement you might want to change DYNALLOC=SYSDA to DYNALLOC=(SYSDA,30). This would cause DFSORT to spread that 469577MB allocation across 29 work data sets (with 1 set aside). So now you need at least 29 volumes that have 16192MB available. If your storage group has mostly MOD 54s or MOD27s defined, that should be fine. If it has something like a bunch of MOD 9s defined, you'd have to increase DYNALLOC further to spread the work space allocation across more/smaller work data sets.
