REORGADON
is a tool for reorganizing IBM's Hierarchical Storage Manager (DFSMShsm) control data sets (CDS). HSM uses three different control data sets - the Backup Control Data Set (BCDS), the Migration Control Data Set (MCDS), and the Offline Control Data Set (OCDS). The control data sets may be used by HSM in a multi-host environment on single or multiple systems. REORGadon provides HSM control data set reorganization while the files are active and online to HSM, and without having to shutdown and restart HSM.
