A storage class definition contains both descriptive and
access-related
information. To identify and refer to storage classes, you assign
each one a unique name that contains from one to eight alphanumeric
characters. Each storage class definition maintains an owner ID that
identifies the storage administrator who originally created or last
modified the storage class. Also, each storage class contains an optional
120 character description field for describing its contents.
