Device defaults

When the device type, or the number of devices for dynamic allocation, is not explicitly specified, DFSORT obtains the missing information from the DYNALOC installation option information supplied by your system programmer.

Note: In rare cases where DFSORT is unable to dynamically allocate the required space using the value supplied by d, allocation may be attempted with a more generic unit name (such as 3390) in an effort to allocate the required space on volumes from a different storage group. Refer to "System Managed Storage" in z/OS DFSORT Tuning Guide for recommendations on controlling data set allocation.
