DFSMShsm manages non-SMS-managed storage on a system basis. That
is, all the data sets on volumes are managed by a system specification,
whether for number of days between backups or number of retained versions.
Primary differences in processing for SMS-managed storage and non-SMS-managed
storage occur in the following processes:
- Uncataloged data sets can be backed up and recovered.
- Users can specify the volume to which a data set is to be recovered.
- Volumes to be dumped or backed up are individually identified
to DFSMShsm.
Unlike space management, availability management of non-SMS-managed
storage has no major differences in the processing techniques from
those that are used for management of SMS-managed storage. However,
there are some additional tasks that must be accounted for when dealing
with the availability management of non-SMS-managed storage.
References to the example system in this topic reflect input needed
to support the tasks for non-SMS-managed storage.
