UNIT_TYPE
The UNIT_TYPE keyword specifies the type of unit on which a data set is allocated.
Syntax
UNIT_TYPE=(OTHER|3390|3380|9345|3420|3480|3490| 3590|ANY)
Notes:
- For non-SMS data sets, the volume serial number must be specified in the JCL or IDCAMS DEFINE to determine the unit type for functions in the ACS and ALLOCATION environments. A non-match occurs if UNIT_TYPE is specified under such circumstances.
- For SMS VSAM and non-VSAM data sets, because the volume serial number is not yet chosen by the system in the ACS and ALLOCATION environments, the unit type is not known, therefore if UNIT_TYPE is specified in the selection criteria, the rule definition statement is considered not to match.
- For new SMS data set allocations that do not have a UNIT and VOLSER specification in the JCL or dynamic allocation request, UNIT_TYPE cannot be determined. If UNIT_TYPE is not known, any UNIT_TYPE selection criterion that is specified in a rule definition is considered a non-match and the rule definition is not selected. Therefore, do not use UNIT_TYPE as a sole selection criterion in environments where new SMS data sets are allocated without a UNIT and VOLSER specification.
