If the data set was non-SMS-managed when it was backed up and is
assigned a storage class with GUARANTEED SPACE during recover, it
is assigned to a volume in a storage group that contains GUARANTEED
SPACE data sets.
If the data set was SMS-managed when it was migrated but did not
have GUARANTEED SPACE, the volumes from which it was backed up might
not be in a storage group that receives GUARANTEED SPACE requests.
To avoid errors, you must do one of the following before the recover:
- Change the target storage class with GUARANTEED SPACE to map to
a storage group that contains the original volumes.
- Add the original volumes to a storage group mapped to by the target
storage class with GUARANTEED SPACE.
