The following set of tasks for using DFSMShsm to manage storage
has been defined:
- Setting overall DFSMShsm system parameters. This task consists
of defining those parameters that DFSMShsm uses, no matter which of
its functions it is to perform.
- Performing space management. This task consists of:
- Defining the parameters that DFSMShsm uses for automatic space
management
- Issuing commands that cause DFSMShsm to perform specific space
management functions
- Performing availability management. This task consists of:
- Defining the parameters that DFSMShsm uses for automatic availability
management
- Issuing commands that cause DFSMShsm to perform specific availability
management functions
- Maintaining the control data sets. This task consists of backing
up and maintaining correct contents for the data sets that DFSMShsm
uses to keep track of the data sets that it is managing.
- Managing DFSMShsm media. This task consists of eliminating not
valid data sets from DFSMShsm volumes and in using DFSMShsm to move
data sets when new kinds of volumes are introduced into your system.
- Determining what occurs in DFSMShsm. This task consists of using
commands that cause DFSMShsm to issue reports of what has occurred
under specific conditions and of reading and interpreting the reports.
- Running DFSMShsm in a simulation mode. This task consists of using
DFSMShsm as though you were managing storage, but having DFSMShsm
only issue a report instead of actually moving data sets. The purpose
of the task is to analyze the results that would be obtained by using
DFSMShsm commands in the way you planned to use them.
- Operating DFSMShsm. This task consists of directing the operations
that start, stop, and interrupt DFSMShsm.
