Specify the name, 1 to 8 characters, of the management class (MGMTCLAS) for a new data set. If you do not specify management class, the wizard uses the default your storage administrator provides through the ACS routines.
After the data set is allocated, attributes in the management class control the following: (1) Migrating the data set, which includes migration from primary storage to Data Facility Hierarchical Storage Manager (DFHSM) owned storage to archival storage; and (2) Backing up the data set, which includes frequency of backup, number of versions, and retention criteria for backup versions.
