For SMS-managed level 0 volumes, the attributes specified in the
storage groups and the management classes govern how DFSMShsm performs
automatic space management and incremental backup. You can override
many of the attributes in the storage groups and management classes
when the functions are performed by issuing specific commands. See
Figure 1 when reading the following descriptions.
Note: If you have converted a non-SMS-managed L0 volume to an
SMS-managed volume, you should:
- Add the volume to a storage group having the desired SMS attributes.
- DELVOL the volume to remove non-SMS attributes. Unexpected failures,
for instance in autobackup processing, might occur if the volume is
not DELVOLed.
