Maintaining storage class definitions

A new storage class might be needed to define the performance requirements of a new application. In addition, you need to add or modify management class definitions and the ACS routines to manage objects that use the new storage class.

Storage class definitions might be changed to accomplish the following functions:

Add storage classes.
Alter the INITIAL ACCESS RESPONSE SECONDS to store data on removable media (optical or tape volumes depending on the Sustained Data Rate) instead of disk space.
Alter the OAM sublevel to store objects in tape sublevel 2 volumes or disk sublevel 2 (file system).
