Steps for defining an SMS-managed tape library

Perform the following steps to implement an SMS-managed tape library:

Determine which tape functions that you want to process in a tape library.
Set up a global scratch pool.
Define or update a storage class to enable a storage group.
Define or update a data class to compact tape library data.
Define or update a storage group to associate tape devices with the library.
Set up or update ACS routines to filter data sets to the library.
Define or update the DFSMShsm tape environment in the ARCCMDxx PARMLIB member.

Requirement: For DFSMShsm processing to complete successfully in a tape library environment, the OAM address space must have at least been started since the last IPL. This requirement exists at initial IPL, as well as after each subsequent IPL.
