Exploitation of DFSMS

The functional areas of CA Disk that support the SMS of DFP 3.x are shown below. Each function area contains an overview of the function, and where appropriate: the SMS fields supported, a construct indicator, the valid entries for that field, and a description of how CA Disk processes the entries. The construct indicators are as follows: MC, Management Class and SG, Storage Group. The storage class and data class need not be considered for this discussion because these classes have no data set management criteria. CA Disk understands 3 different media upon which data can reside (IBM storage states are shown is parentheses): primary (level 0), disk archive (level 1), and tape or other media (level 2).
