For SMS support of the tape
library, an SCDS of the proper level
must be activated. This SCDS must contain appropriate library definitions
and tape storage group definitions. Information that the storage administrator
must provide specifically for an Automated Tape Library Dataserver
(ATLDS) or manual tape library (MTL) is listed below. See z/OS DFSMS Implementing System-Managed Storage for
more information about MTL and ATLDS.
- Data compaction, media type and recording technology information
can be included in data classes that are used in allocation of devices
in a tape library.
- New storage groups of type TAPE must be
defined. The storage groups
are involved in the allocation of new data sets to volumes within
a tape library.
- A tape library must be defined in the SCDS.
- Default data class defined to the library.
- ACS routines
must specify a storage class and the storage group
selected must be associated with a tape library.
