Tasks for automatic availability management

Now that the functions that the example system can accomplish have been described, the means to make the example system accomplish these functions are described. The tasks for controlling automatic availability management of SMS-managed storage require adding DFSMShsm commands to the ARCCMDxx member and specifying attributes in the SMS storage classes and management classes. It is assumed that the storage classes and management classes have already been defined. The attribute descriptions explain the attributes to be added to the previously defined storage groups and management classes. Similarly, the descriptions of DFSMShsm commands relate to commands to be added to the ARCCMDxx member of SYS1.PARMLIB.

Two groups of tasks are performed for availability management: dump tasks and backup tasks. Each of these groups of tasks is described separately.
