Use EDGBKUP to reorganize the control data set. The DFSMSrmm subsystem must be stopped or
quiesced when you reorganize the active control data set. DFSMSrmm reorganizes the control
data set by first backing up the control data set and optionally the journal. Then DFSMSrmm
restores the control data set from the backup control data set. Refer to the DFSMSrmm
Implementation and Customization Guide for details on CDS space planning, allocation,
reallocation, backup & reorganization.
