Making Unmovable Data Sets Eligible for System Management

Once you have identified the ineligible data, you can do the following:

Convert ISAM data sets to VSAM key-sequenced data sets (KSDS). Programs that access the converted ISAM data sets can then do so in VSAM format using the VSAM/ISAM Interface Program (IIP).

Identify unmovable data sets that can be converted to movable data sets. Move these data sets to system-managed volumes. Pool the remaining non-system-managed volumes containing the unmovable data sets.
