The disk/pack option controls the location of the data set. In the absence of any specification, the data sets are assigned to disk. When DISKPACK or PACK is stipulated but no family name appears, the data set is assigned to the system resource pack. When a family name follows DISKPACK or PACK, the data set is placed on the named pack family. The data sets can also be assigned to a named pack by using the PACKNAME or FAMILYNAME option with KIND = DISKPACK or KIND = PACK. The PACKNAME and FAMILYNAME options are synonymous.

The value for the <disk/pack> attribute can also be changed by performing a DMCONTROL operation.

If you decide to change the family name by way of a DASDL update after you have changed the name by using a DMCONTROL operation, you must perform a control file override. The Override enables the system to recognize that the family name in the DASDL update takes precedence over the name you specified in the DMCONTROL operation.

For additional information about the DMCONTROL operation and its OVERRIDE FAMILY option, refer to the Enterprise Database Server Utilities Operations Guide.
