The PERMANENT UNIT NAME field specifies the device type or unit name that is to be used for allocating data sets that are created during installation or migration.
| Acceptable values: | blank, valid device type, unit name |
|---|---|

| DSNZPxxx: | none |
- ICF catalog
- prefix.DBRMLIB.DATA.suffix
- prefix.RUNLIB.LOAD.suffix
- prefix.SRCLIB.DATA.suffix
- The two data sets that the DSNTINST CLIST generates:
- prefix.NEW.SDSNTEMP
- prefix.NEW.SDSNSAMP
The value of PERMANENT UNIT NAME identifies a direct access unit name for partitioned data sets and the ICF catalog. If you want to use different device types for different data sets, edit the installation or migration jobs after you complete the tailoring session. A common device type is 3390.
The value of PERMANENT UNIT NAME is sometimes used during IVP processing to place output (from COPY TABLESPACE, for example) on the device type that is specified for the PERMANENT UNIT NAME field.
A change to PERMANENT UNIT NAME during migration does not affect the ICF catalog, Db2 catalog, directory, or logs. The new value is used for data sets that are created during migration.
